Title: half-broken 200SBi-what could be the cause?
Post by ps47 on 30.09.07 at 01:33:54

the card installs fine and runs stable,but shows artifacts when running 3dgames (other hardware/software/drivers are not the issue,same system runs a fully working SBi without problems):

incubation (glide2x,2d menus/sidebars are displayed correctly):

hitman1 (glide3x,everything looks bad):

I'm wondering,what could be the source of the trouble? memory,FBIs,TMUs? if I could track it down I may just be able to fix (or let someone fix,to be precise) the card (plenty of spare chips lying around)..

If 2d runs fine, then i guess its the memory....tmu, or texture unites usually either freeze or show selective artifacts on textures.

maybe a driver problem ?

these artifacts are typical for broken memory :-/

nope.as I said,the same system runs another 200Sbi without problems.

I'll try inspecting the board closely,maybe I'll find some broken ram pins or something..

because all the artifacts are rasterized, i guess its the RAM where the ouput picture for the RAMDAC is prepared :-/ hope you can find something visible on your card :)

nope.the broken card looks in better shape than the working one.this will be tough :-/

I don't know which 200SBi you have (green or black) but perhaps you could find some donor Voodoo 2 cards and use their RAM and a GENDAC chip to replace the ones on your 200SBi?

got a v2 with a damaged text. unite (hopefully framebuffer's and 2nd's tu's mem modules are ok) if you want (had a giveaway thread but no one wanted it).

methinks I'll be better selling it off the way it is-I dont like the idea of resoldering of 48 memory chips myself ::)

its a green one btw..

So... If you decide to sell it I would be interested into buying the card as it is (if I could cover the price).

gone already..one more info-after disabling SLI the artifacts were gone,and that probably means the bad memory is somewhere on the slave v2 chipset.we'll see if the guy from CZ manages to fix it..
