Big thanks for Hanksemenec and Mikulaish, this project could never finalized whithout them helping and supporting. Mikulaish provided the extra 32 Mb RAM chips and the BIOS-hacking; Hanksemenec provided tech-info's; I just provided the Voodoo 4 4500 AGP and soldered the memory. After flashing to hacked BIOS I got myself to be the proud owner of this long waited 64Mb RAM single chip VSA 100 video card!
The card is perfect working; all 64Mb RAM are being used. I will post more details as soon as I can spare some free time (I am at work right now...).

congratulations! really good work  ;D

please post some benchmarks with 32 and 64MB RAM...

I would just like to add that changing the strapping resistor configuration didn't help recognising the extra memory. The only modification needed is in the bios (stricly my opinion for now, don't shoot me if i'm wrong). There is a bit that defines the no. of memory chipsets. It has to be changed from 0 to 1, meaning 2 chipsets instead of 1.

will you release the bios or will you keep it a secret like denisf?

I just posted the necessary changes, and i have just modified it for Osckhar. I'm not that selfish. I don't even own a v4   :). But to be certain of the bios, yours, TM30, would really help. Could you dump and send it to me, please?

@mikulaish
I will try it this afternoon.

Thank you,
Oscar

hmm amazing that the boot screen shows 64MB of ram, now I wonder how it will do in games :) it should do fine since that the bios does show the True Total Memory Capacity properly :)

Nice work lads. 8)

;)

I would like to see full details and bios image.
I have all means and equipment to do it myself this very moment.

If I were you, I'd politely ask.  ::) Demanding is really offensive, and unproductive.

st4r4m4m4 do you have a "solder-station" ?
cause i think with a generic soldering iron this is impossible ;)

@mikulaish: would you send me the bios and tell the hex-address? i will send you my email-address...

Here is a package of two moded bioses:http://bandi.uv.ro/3dfx/v4_64mbyte.zip One for the standard v4 and one for the DVI version. Enjoy!

@TM30
I don't have an ordinary soldering iron, I mean I have a soldering iron too, but I got some more proper soldering gear for the task.
As you said about the ordinary soldering iron.. it would be suicide hehe

@mikulaish
Ordinary web client (Firefox) returns some wierd error message  ???
wget works thow :)

i was the nvidiot, and you are not being nice...  >:(

Wow :o

This is great ;D


Good team work 8)

So when does production begin and how much are you asking for one of these jewels

I've rehosted the file for mikulaish for anyone that has probs getting it

I hope everyone remarked Komponent, the starter of this topic. He disserves all the credit for this achievement. Without his work this would not have happened. He was helped from here and there, but in my opinion he should be considered "The papa of homemade v4 4800"  8) RESPECT!

Hello again!
As I promissed, I'm back with some benchmarcking with Voodoos:
For starter, let me say that all the testing was done using 1024x768 resolution with 32 bits colour compressed textures.
The platform for all the tests was:
MB Syntax Via KT 266A ("crap") + CPU AMD Duron 1100 Mhz + 256 Mb RAM Sycron DDR @ 200 Mhz ...
... plus some great toys: enter the Voodoos: Voodoo 4 AGP 64 Mb (recently moded from 32 Mb), Voodoo 4 AGP  32Mb, Voodoo 4 PCI 32 Mb and Voodoo 5 5500 AGP 64 Mb.
No overclocking was used; sorry for the small scores; I'm seeking for a better CPU but I'm preety low on money now...
I was runing MS Windows 98 SE + UnOfficial SP 2.1A and for benchmarcking I used 3DMark 2001 SE 330.
I tested the performance of the 3DFX cards with and without FSAA. The driver used was Raziel64 Evolution 1.01.16 for Voodoo 4/5 and Windows 9x/Me. The DirectX verssion was DirectX 8.2 .
The Voodoo 5 AGP was runing in AGP 1x mode; for Voodoo 4 AGP I used AGP 4x mode and, of course, Voodoo 4 PCI was runing in PCI 33 Mhz mode.
There are the results:

Voodoo 4 AGP 64 Mb AGP4x :
No FSAA : 1576 3D marks

Feel free to comment on the results I got!

If you like I can try the bios on my 4800 card and post the results.

@Komponent: Great job! It seems like the extra memory is really being used! Congrats!
@Gary: Personally, I would really like you to try it out...  ;D The moded bios worked for osckhar so it should work for you as well.

thanks alot for the bios...but i have a question!

but first of all the point of editing the mem-chipsets! i compared your bios with the original Voodoo4 4500 AGP 1.15 bios...
http://img115.imageshack.us/img115/1750/tdfx18pa.th.jpg

here the details of the bios (4800-4500)
http://img115.imageshack.us/img115/7629/tdfx22rf.th.jpg
you changed:
tBWL BKWR to Pre from 1 to 0
tRL to PRE from 0 to 1
Number of Sgram/Sdram chipsets from 0 to 1

why did you changed the first two values? are they neccessary to gain the extra ram?

wrote on 21.04.06 at 17:20:17:

If I were you, I'd politely ask.  ::) Demanding is really offensive, and unproductive.

Yaaayyy ::)

@ Komponent

Rather amazing those 3D Mark scores :) FSAA x2 on a Voodoo4 4500 with 64MB does more with MAX FSAA that a Voodoo5 with max FSAA, that may be because of the faster ram timings.

Very interesting results  8)

About the first two values: they do not need to be changed. This is my bad. Tdfx bios editor chages stuff by itself sometimes when something is edited. I changed those values back to default and uploaded again. In the DVI version this was corrected in the original package as well.

maybe you can post a benchmark with these two values changed and not changed...maybe they don't change anything...maybe they change something....

that would bring the real performance of +32mb...without any  changed timings etc...

First of all I don't own a V4. Komponent owns the homemade V4 4800. As i said before, the DVI bios had the default timings in the original package. Osckhar did his benchmarking using the correct timings in the bios, and as you can see, there is a difference between 32 and 64 mbyte.  Still Hank's opinion would be wellcome and very much appreciated, but it seems to me that the extra memory is being used.

Congrats to both of ya. Great work.

The BIOS that I used for testing on my moded Voodoo 4 with 64 Mb had a few changes oposed to the standard 3DFX 1.15 original BIOS, other than the necesary change of the bit that controles the number of memory banks. Those differences occured not intentionaly and they were fixed into the latest "relese" of the 4800's BIOS. This last one, publicaly available by the courthesy of Mikulaish, has only one change made to the original 1.15 BIOS, as described above. The rest is identical, including RAM timings. Today I flashed my homemade Voodoo 4 4800 64Mb with this release and I have done the exact same testing work as previous, to be able to compare the results with those I got yesterday.
Here are the numbers:

Home-made Voodoo 4 4800 64 Mb @ AGP 4x :
No FSAA : 1578 3D marks
http://img126.imageshack.us/img126/1083/v4800agpnoaa1mk.jpg
2x FSAA : 804 3D marks
http://img47.imageshack.us/img47/6787/v4800agp2xaa0wo.jpg

I'm loading up a test machine now, I should have some numbers later tonight.

It is working- While testing at 800 x 600 x 32 bit color (the highest my current test LCD will go) there is a 200 point spread when the extra ram is activated.

32 mb = 2300
64 mb = 2500

<numbers averaged>

Test system is KT-266 with 1800+ 256 mb and Win98

http://www.3dfx.ch/gallery/d/12987-1/4800_2.jpg

http://www.3dfx.ch/gallery/d/12989-1/4800_3.jpg

After comparing the new BIOS and the old one with a hex editor the only change is the bit for number of SDRAM chipsets.

I wonder why the card was flashed so?

It was noticed while running 2001SE there was some  minor texture flashing the was no longer present with the extra ram activated.

Functionally, is there any difference between a "true" 4800 and a "modded" 4500 with 64MB and the BIOS flash?

I would not think so but only Hank could answer that I think.

Regarding the bios this question could be answered IF TM30 would send me or post his bios from his original 4800. I don't really see that happening...

Really :-/

I thought TM30 dumped his BIOS for Chosen_One.

Just ask him politely and maybe he will answer ::) LoL ;D

Ach ja nicht aller menschen haben die selbste karakter lol.

P.S. And I believe I was not the only one...

Come on guys, were all friends here. Do we have to use aliases :P

I'm getting confused on who's who ::)

I agree Gamma LoL haha oh well some things are rather obvious than they really are or should be ::)

Rather funny to be honest  ;D ;D ;D

First off CONGRATS to all those involved in this...uhm... :-/

!!!UBERMOD!!! 8) 8)

(yeah that's about right!) ;D

@Hanksemenec - Props ;)
@Mikulaish - Big Props :D
@Komponent - Props with jingly bits on them! ;D

Secondly...NO STUPID ALIASES / SPAM TACTICS! >:(

Let's keep the thread focussed people! ::)

Third - how about some 32MB / 64MB screenshots comparison. ;)

(a good test would be UT2004 due to it's large textures) :D

I might use funny nicknames, but i think i make it clear that it is me.  ;) If not, than I state that I am the one posting under different aliases. And again bios-wise TM30 could clear this up, and hardware-wise if TM30 an osckhar could compare their copper bords to see if anything is different. Anyway 3 different people (Adrian aka. Komponent, Gary and Oscar) have tested their V4 4800, and all 3 had results that show a performance increase since the extra memory is activated.

... and what a pain in the "back" was that info that a hardware mod was supposed to be required rather than a simple BIOS hack! I had to strugle with different resistors configurations on the PCB, some sugested even by Hanksemenec, some of my own ideeas with no luck. Good thing that when I became tired of changing resistors, Mikulaish thought: "Let's try with this BIOS-mod too..." (nothing to loose, right?); there are out-there a few prototypes with full out-of-the-factory 64MB RAM soldered (I know about Gdonovan, Oskhar and TM30's cards) but mine being a regular Voodoo 4 4500 designed for 32Mb might just not had the hardware capacity and compatibility to accept additional memory... (cool thing it prouved to finaly be something like a easy task).

Mikulaish is just being too modest. It was realy team work; everyone of us contributed; I consider a nonsense to call someone the mastermind behind this project or who desserves better credits for the succes; I just happened to end up as the proud owner of that jewel that is this first confirmed and prouven beyond doubt home-made Voodoo 4 4800 (realy, maybe we shouldn't even call it this way; it's only the average Voodoo 4500 that we modded...).
So, RESPECT! back at you Mikulaish, RESPECT! to this great 3DFX community!

can you bench the modded bios with changed timings and the modded bios without changed timings?

1x (changed timings)
tBWL BKWR to Pre at 0
tRL to PRE at 1
Number of Sgram/Sdram chipsets from 0 to 1

1x (timings are original)
tBWL BKWR to Pre at 1
tRL to PREat 0
Number of Sgram/Sdram chipsets from 0 to 1

i want to see the difference if there is one...

How were you able to solder the memory on?

Wouldn't it be nice to get 64MB of some faster SDram for the next one? Think of the OCablilty :o

Would anyone realy be interested? I didn't thought about realising this mod again, for other people; we did it just to prouve it can be done.

My dayly Job is as a computer service technician and I used one hot air gun a.k.a. heat gun to solder the RAM chips. About the other issue: faster RAM is hard to find...

I was thinking that maybe the some faster ram off of a (dare I say) nVid card could be salvaged for the project.

hehe good idea, those Geforce2 MX400's and GeForce4 MX420's have good 128Bit SDRAM :)

_{to be very honest I rather see a NV card get dismantled than a precious 3dfx or ATi card ;D}

Yep ;D That's the ticket ;)

I do own 4.5ns EliteMt memory chips (222Mhz), but the problem is that the GPU is limiting in OC for VSA100 cards. There are two types of sillicon for the VSA100: the 220 and the 320. The 220 has a bug and is not able to reach 183Mhz (exceptions might occur). The later 320 (my 3700A has it) can be overclocked to as high as 200Mhz with 6ns Hyundai ram.

you can do a voltmod on this card, so it easily can go over 200Mhz...

True, but above 2.82V (default on my 5500) the heat will kill the chip. I'm not talking 2.9V, because that does not help too much. Maybe for one crazy experiment it would be interesting, but it doesn't really worth the effort. I know for a fact that EliteMT 4.5ns memory is supposed to reach 222Mhz, but it only reaches 220 with normal timings. I beieve that Hyundai 6ns might reach this speed as well. It could be tried on a GF wich has this memory by margining only the memory clock speed. If anyone has the resources, parts, time and patience to do it, i wish him luck!

do you have a link to a 4500 vmod? i wanna mod one of my cards and see what i can get...

@Chosen_One: I mean 355-0026-220
@TM30: I don't have a volt-mod scheme, but i might find a way to do it. I still need to buy a V4. It might be a little difficult from pictures. ::)

@Komponent - ooh! A got air gun! :o

Do you know where I can get one of those? ???

Do you have a picture? ???

I've been wanting to get my mitts on one for a while and wondered how much it would set me back... ;D

When I got the job at the computer-service, the hot air gun was allready there; actualy my boss has it but he granted access to it for this mod. I will ask him about the price and I'll try to take a picture soon if this will help you.

Hrm, okay - at least I know what they look like... ::)

Good work there on the card, but it appears you have flux all over the card on some of the components, get that washed off ASAP  ;D

Will there be any exact detail on how was the job done?
Info about needed modifications, by that I mosly mean details... like resistor placing, values, any other eventual element to be added/removed, any warning etc...
I'd guess I'm not the only member/visitor interested on getting the job done for own use, so I'd be glad seeing it posted here.

As stated before: resistor change is not needed. You only need to solder the extra ram and flash the moded bios, or mod it yourself.

Guess I haven't catched any explicit statement, Thanks anyway for the clarification, I'll do my best to try it out myself as soon as possible (after exam period) ;D

I still have my system setup if anyone wants 32 vs 64 mb benchmarks.

yeah why not!

Actually, i was thinking more along the line of Screenshots... ;)

Comparing the 32MB screenies to 64MB versions for texture heavy games such as U.T. 2003 / U.T. 2004 ;D

Just a thought! :P

Today another V4 4800 was born  ::). This is a hybrid, using Hyundai and Toshiba memories, which are getting along in perfect harmony.

Cool 8)

Like to see some pics :)

Yeah! Very good work! Much cleaner than mine... It looks very professional. A job well done Mikulaish! Anything new to come?

anybody try this with a 5500 yet?

A new 64MB-mod is done:
http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_01.png

I've used the memory from a 3D-Prophet 4500.
That are 5ns Samung chips. look here: http://www.xbitlabs.com/articles/video/display/kyro2.html

I tested the card only on a p3 850 PC -> no performance increase with 3DMark2001SE  ???

But it's possible to overclock the card up to 193MHz. Perhaps with better cooling more can be reached.

hmm I suggest that you flash the card with a Voodoo 4 4800 AGP 64MB Bios, that bios should take advantage of the extra installed ram.

Umm...but I guess he already did... ;)

@gtxe's screenshots show 64MB in windows... ;D

@ gtxe

How did you do the soldering ? Which tools did you use ?

well I reckon he didn't because if he did use the 4800 AGP 64MB Bios why does the DirectX program see it as a 4500 AGP with 64MB instead of a 4800 AGP with 64MB like all other people have done?

Yes, i flashed the bios: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_02.png
I've only changed the bit for "Number of Sgram/Sdram chipsets".

If you don't flash, only 32MB are shown.

what pahhen when you flash bot dont add the 2nd chipset?

A new 64MB-mod is done: I've used the memory from a 3D-Prophet 4500. That are 5ns Samung chips.

Hell-yes! "The best of both worlds": more and faster RAM too. This should be the ideal combination, 64Mb 5ns memory per VSA100. I would love to see some pictures with the modded Voodoo4!
If tested with FSAA 2x the Voodoo4 with 64Mb RAM should show a important performance gain over the regular 32Mb one; that is anyway the clear result that I got with the Voodoo4 that I modded myself.

Indeed, screenies and benchmarks would be very nice! 8)

I have to borrow a digicam from my brother... then I will make some photos (next week).
Benchmarks: I will test the card in an other computer (MobileBarton@2083MHz).

did u change all memory modules ?
and replace them with 5 ns ram from Kyro card ?
or only the 4 module ?

And can you test some games that require 64MB VRAM like NfS: Something ?
Would be cool to see the voodoo with such a game.

or a 20MB Voodoo2

with 8MB per TMU

I tried Codename Panzers: Phase 2 with a Voodoo4.
The game requires 64MB, it does not run on a 32MB V4 but runs fine with a V4 modded to 64MB.

all 8 chips from the kyro2 are now on the voodoo  8)

I'll try "Codename: PANZERS - Phase Two"-Demo. But i must download it first.

Edit:
SFFT41-Driver was necessary for the Multiplayer-Demo:
with 64MB BIOS: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_03.jpg
with 32MB BIOS: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_04.jpg
so I think the momory is working correct.

Edit2:
here the benchmark-results...
Voodoo4 32MB 166MHz: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/3dmark2001se_v45k_32mb.png
Voodoo4 64MB 166MHz: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/3dmark2001se_v45k_64mb.png
Voodoo4 64MB 193MHz: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/3dmark2001se_v45k_64mb_193mhz.png

Systemspecs:
MobileBarton@~2,1GHz
Epox 8k5a3+
1GB Memory
Win2kSP2
SFFT41-Driver

With P3 850MHz there were no differences in the bench-results.

The link in page2 of me mirroring the bios image for mik is broken due to domain expiration... so heres the new one, if anyone needs it =)

(so busy lately to hang around here @_@, never forget tho ;) still keeping my cards as a treasure)

Nice job gtxe !

anyway, did you try to change the orignial cooling ?
by using a god thermal paste ( like AS5 ), you sould be able to overclock the card up to 200 MHz.
It's only the VSA now witch  don't go further ...

Question: The evilking voodoo4 models are very bad for overclocking. Mines show already artifacts at 170MHz. Any hint ?

Br.
Radu.

hm... it's not so easy to mod the cooling...
because of the nonstandard mounting holes.
So I need some tools I don't have :(
Cooling the board on either side would be nice  8)

Any screenshots? ???

A modded Sockel A Cooler is now cooling the VSA100.
200MHz are no problem now  :D

Screenshots will follow...

Hels gtxe haha Crikey!what about core/mem 220Mhz maybe possible?

no way... there are artifacts already at 205MHz.
But 200MHz is stable for long time, even at 2xAA (no crashes, no artifacts).

hmm FSAA x2 tests in games like UT GOTYE 1999 & Dark ForcesII: Jedi Knight & Descent3 @ 1024 x 768 x 16 in Glide would be interesting :)

Screenshots of Unreal @ 1024x768x16bit 2xAA:

heh looks nice gtxe :) hmm Descent3 is a good idea for my Voodoo 5 5000 AGP, I'll see hwo it will handle it :)

thx for the great screenies  8) was the gameplay fluid with FSAA x2 at those reso's?

What program did you use to make the screenshots as lighted as the are ingame?

There is a driverbuildin screen-capture-hotkey (Amigamerlin 3.1-R11):
http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshots/screen_capture_hotkey.png

The sceenies look the same as in the game (brightness and colors).

I have done some more benches:

Descent 3 @ 200MHz, 2xAA (I did the bench like described in 3dcenter.org): 51.71 fps

All benches are done on a Pentium III 850MHz, Win2k, 512MB RAM, 1024x768x16bit

omg @ 200Mhz the 4500 is very impressive with max FSAA :o :o :o
nice one there mate. hmm that screen capture key in't supported with the 3dfx tools for 98SE, the one I'm using now is from AmigaMerlin 2.9 for 98SE combined with  3dfx Voodoo4/5 V1.04.00 aka the latest Official 3dfx WHQL driver.

I used the AmigaMerlin 3dfx tools because it has much more usable settings for the 5000 AGP to make use of :) still no Screen Capture key within it, that would be a nice fix for a newer 3dfx Tools control panel for 98SE people.

@st4r4m4m4: where did you get the bios? are they from the real 4800 with & without dvi or did you modify them by yourself?
inside the bios i read two different stings...the first says "Voodoo4 4500 BIOS - Version 1.15" & "Voodoo4 4800 with TV and LCD support BIOS - Version 1.11" in hex....in the string you can read in the postscreen the bios says "Voodoo4 4800 BIOS - Version 1.15" and "Voodoo4 4800 with TV and LCD support BIOS - Version 1.11"

so are they real or modded?

very impressive the performance improvement.
Can u post pics with the moded card ? I'm interessted to see the cooling solution.  ;D
It's a cooper cooler ?
210 MHz solud work with the 5 ns memory and cooper cooler.

Radu.

If I get the camera again, I will post new photos.
It's an aluminum cooler. The backside is cooled too. It looks gigantic.
2 PCI-Slots (under the AGP-Slot) can't be used anymore  :o
Even at 200MHz the card is cool. I think with a cooper cooler it will not be better.

tried a vmod already?

I don't want to continue the v4-64MB-200MHz-mod. It was just for testing.
v5-128MB-200MHz-mod would be interesting now. But it's difficult (almost impossible) to get the right memory chips. Look at this topic: Regarding faster memory

so to do this it is only need to get 4 same type of ram then solder them on it and load new bios?
my V4 got toshibas F54044 mem
whoah I might do that for my V4, but it's my only one  :-/ so I doub could i risk it
does anybody know how to vmod V4?? Iwas thinking to do full scale modding for it ram, vmod, new cooling (if I only find suitable heatpipecooler ;) ) what else??
and V4 supports agp1.5v 4x speed so Ican use my asrock 775dual-vsta to build 3dfx gaming rig

Guys,

I have a KyroII with 5ns ram, does that mean that theoretically I could fit my voodoo 5 with this ram and have 64MB of 200Mhz ram on there??

If it has 8 chips and your VSA-100 chips can run at those speeds, then yes.

well,

I checked and it has 8 chips with the following print:

SAMSUNG        118
K4S643232E-TC50

and I did already have my 5500 clocked at 183Mhz before, so ......one can only hope.

Have to check with someone if they can do the soldering for me, as I have neither the equipment not the experience to undertake such a thing.

Would be interesting to run benchmarks that with 32MB would drag down the card (e.g. Aquamark 1 @ 24MB Textures with 2x FSAA).

The difference between 32 and 64MB should be dramatic there.

actually,there are some test results available (v4 with 32mb vs v4 with 64mb),in case someone is interested.in certain situation,the speed boost is as high as 285% ;D

one of the cz guys has both v4 with 32mb and v4 with 64mb..

What other video cards have same type memory that V4 use, someone said that he took memory from Kyro.
so would like GF 2MX has V4 compatible memory

Some Geforce2MX cards have compatible memory, for example a special V7100Pro from Asus.
The card has to look like this :
http://cgi.ebay.de/ASUS-V7100-Pro-GeForce-2-MX400-zwei-Video-OUT-4x-AGP_W0QQitemZ330271032770QQcmdZViewItem?hash=item330271032770&_trkparms=72%3A1123%7C39%3A1%7C66%3A2%7C65%3A12%7C240%3A1318&_trksid=p3286.c0.m14

A new 64Mb Voodoo4 AGP has been created for G1nX/RaverX. Perfect function as allways, ofcourse.

Would it also be possible for you to resurrect and dragonize cards with dead ram?
