SLI BIOS & SP difference

post #1 of 7
Thread Starter 
hi guys! i've just recently realised slight difference in my SLI set up. i have few questions that my tickle your brains a bit.

i have two ASUS 8800GTS 640MB cards. one i bought as soon as 8800 series came out, and another one about 4 months later.


in GPU-Z the differences:

Slot 1:
BIOS: 60.80.0A.00.11
Shaders: 96

Slot 2:
BIOS: 60.80.20.00.01
Shader: 112

the rest is the same...

Questions:
1) is that some sort of glitch or the newer card has more Shader Processors?
2) will i gain any performance if i put newer card in Slot 1?
3) should i flash the 60.80.0A.00.11 card to newer 60.80.20.00.01 BIOS?
4) should i flash both cards to newest BIOS and will it make any difference?

thank you in advance!

it seems like a big pile of confusion came out from nVidia. they like to stick to model numbers aven though the parts are slightly different...

If the clocks are the same, it makes no difference

i've tested with 3d mark 06 both cards... results:

- so there is difference! its very interesting that the score is higher when the older card is master.

also i've tried flashing bios on older card to 60.80.20.00.01 version usin NVFLASH (5.67). but had no luck... the error is "ERROR: BOARD ID MISATCH". tried overriding the settings using -5 & -6 but no chances... looking for solutin now.

could anyone give me some advise to how i override BOARD ID MISMATCH error please!

I too have noticed that there is a bios difference between my two cards. Weird, though, cause they were bought at the same time. o.O

have you tried benching them in different slots?

there were 112 sp and 96 sp GTS's made
all I can say is, use the 112 sp card on top? seems to work better.

and my GTS512's have different BIOS'es, different manufacturers and different clocks, so yes, NV is a little confusing lol
