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

2x FSAA : 803 3D marks

Voodoo 4 AGP 32 Mb AGP 4x :
No FSAA : 1471 3D marks

2x FSAA : 661 3D marks

Voodoo 4 PCI 32 Mb PCI 33 :
No FSAA : 1358 3D marks

2x FSAA : 624 3D marks

Voodoo 5 AGP 64 Mb AGP 1x :
No FSAA : 1950 3D marks

2x FSAA : 1401 3D marks

4x FSAA : 602 3D marks

Feel free to comment on the results I got!

It seems like the extra memory is really being used! Congrats! @Gary: Personally, I would really like you to try it out... 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...

here the details of the bios (4800-4500)

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?

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)

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.

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.

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

2x FSAA : 804 3D marks
