Maxed 6800gs AGP - Page 5

post #41 of 44
pbasil1, how are your temps running that high clock before and after the Zalman cooler. I'm waiting till friday for the VF900 to come out so I can get my temps lower. Mine idles at about 54 and load (OC'd to 420/1200) is about 78 and that is with some AS5 under there.

Hi there buddies!!!

I'm from Brasil, and I have an eVGA 6800GS modified via bios to Ultra. I've made a guide that you can check here:

GUIDE HOW TO MOD YOUR 6800GS TO ULTRA EXTREME

But I've seen here that many folks can't reach 450 MHz, even with 1.4V setted up with NiBiTor. I ask: have you tried to set 1.4 to 3D and 2D? This could help, maybe...

I can't pass to much 450 MHz at all, even with a Thermaltake Volcano 10+ Slim adaptted on him. And I was thinking in elevate Vcore with "physical voltmod". But, after read some posts here, I found this image:



But I have a doubt: under "Voltage Table Editor", what "Entry" should I change? And about "VID"? What it means? Should change too?

Thx to all!!!

Hey welcome, and nice guide.

I've been trying the pencil mod for the VGPU and VDDR, from VR-Zone, but whenever I make the lightest possible stroke to the resistor, the voltage skyrockets from 1.33Vgpu to 1.68Vgpu or 2.03VDDR to 2.58VDDR and the my screen loads with lots of crazy boxes and "artifacts", which is described as a safety measure on the 6800 series cards.

So eventually I just settled on the .1V (resultant VGPU = 1.43V, checked with multimeter) increase in vgpu by using nibitor and flashing bios. Before the .1V increase I had 385mhz on the core, after I was able to get 420mhz but I lowered it down to 410mhz because the card artifacted once the temps reached 75-80C.

How did you manage 450mhz on the core?
Did the Thermaltake Volcano 10+ Slim help that much? I think it might be a better investment than the NV Silencer 5, VF700, or VF900 VGA coolers if you have reached that core frequency with stability and no artifacts.

Thanks.

First, I've tried to adapt only a fan:



But that way, I only reached 430 MHz. So, I bought a TT Volcano 10+ Slim and put 1.4V on 3D and 2D under NiBiTor and these did the trick to reach 450 MHz. Here you can check some pics:









Now, I can run at 450/1185 MHz without artifacts and with ~44°C idle and ~55-60°C at extreme full load. It's very nice temps, don't u guys think? And consider that I live in Brasil, a very hot country almost all year!

BUT, I can't pass 450 MHz easily without artifacts. In facts, 455 MHz...Can someone tell me how can I high the Vcore under "Voltage Table Editor" in NiBiTor safetly? What options should I change? I mean, what "Entry" should I change? And about VID? What is this? Should change too??
