6800 Go Successful Bios Flash - Page 19

Wow this is some interesting BIOS hacking. Has anyone actually verified that the voltages of 6800 Go are controlled by the BIOS? That's about the only difference between the NV42 non Ultras and the Ultras.

If anyone ignites their laptop I want photos!

Ran at 487/1200 for over four hours in EQ2 last night. I'm going to try 500/1250 next I think.

3dmark05:
450/1060 = 5140(ish)
475/1200 = 5550
487/1200 = 5650 (88C in RivaTuner monitor log using ATITool)
500/1200 = 5752
500/1250 = 5850

I think the formula here is for every 50 MHz of memory of 12.5 MHz of CPU, you're going to get another 100 3DMarks in 3Dmark05.

question, can someone provide a link as to where I can buy the geforce 6800 go ultra gfx cooler? i'm interested in flashing my non-ultra too (after some of you brave people try it first of course)!

You cant buy it without the ultra card. The heatsink is a non serviceable part.

You know if the Sager and Dell bios are completely different in hex view its because they are different versions. Have any of you ever looked at a driver file between versions? Hardly any of the hex addresses match up so I'd assume the same is true for the two bios's. If someoen has the balls (I don't since this is my only pc atm) I'd be curious to see what happens when you force flash the sager bios.

Effect of overclocking and driver selection on real-world game performance (FarCry).

HDR severely limits these cards and isn't used in too many games. Disable it and run comparisons with AA/AF cranked up and see if it makes a difference - I'm betting the extra fillrate and bandwidth will definitely come in to play.

I'm still running @ 525/1250 with no issues for about 24 hours now.

Try running 3dmark03 and tell me what happens during the nature test.

I am updating real-world gaming results for FarCry with no HDR, will be edited in my previous post above.

Will Try

I will get my hands on a 130w AC adapter.
I AM willing to try, but lower clocked first, to see if it handles GDDR1!

Just need to get the cooler first...

Can you run 3dmark2005 at the different speeds... but with 1920x1200 for the resolution?

I'm curious if it makes a bigger difference at higher resolutions.
Stock XPS2 I just got 2927 at 1920x1200 with the 76.50 drivers

It crashes on nature for me too @ 525/1250.

I dont get it. It runs farcry, doom3 and hl2 fine at 530-1250 but crashes out of 3dm03 in the nature test at 500-1250

My new 450/1100 bios don't crash it... I don't know what would cause that....

UPDATE: real-world game performance in FarCry.

Well, I just set mine to 525c1250 and it crashes at the end of 3dmark05(not 03).

I am hoping to get this score as high as I can then when my new system gets here I wont have to worry about it.

Btw, I talked to Dell and they are sending me a new gen 2 due to some other issue I am having.

Post your 3DMark05 differences too...
