volt mod and performance for 8800 GT with aftermarket cooler

post #1 of 10
Thread Starter 
Could someone tell me wot voltage can my 8800 GT evga SC support atm i got it OC @ 700 core clock ,1670 shader clock , 1000 memory clock
Didnt get any artifacts at all in ati tool 0.26 even 1 single yellow dot i didnt get for 10 minutes
I changed my voltage to 1.1v btw
Temperatures i see in ati tool are 39 gpu temperature and 32 temperature of temp chip I tried to go higher with OC but @ 720 core clock i start seeing yellow dots
By the way could someone tell me how much temperature you win with HR-03 GT in comparison with accelero s1 rev 2
atm i got 2 coolers 92mm fans with aftermarket cooler accelero s1 rev.2

I forgot to tell those clocks I OC it with stock cooler

HR-03 GT is a great cooler if you get a good fan for it. Probably the best.

As for volts, I would say 1.3-1.4, but dont push it, start lower. THis is for a hardware voltmod btw. BIOS i dont think you can get above 1.1

Physical volt mod or BIOS volt mod?

As the BIOS one can only go to 1.1 if you lucky.

I would stay below 1.45, however the over-voltage protection kicks in at below that, and there is a special volt mod to overcome that too.

I hit around 800 on my 1.25 volts.

For a cooler, an HR-03 is great, but takes up a ton of room. I went with a Thermaltake Duorb, and it keeps my card under 55 load. Also it is only dual slot.

Duorb, or a VF1000, both are great coolers. My VF gives me 48 load at 846 on my GTS.

How much do you know about circuits? Do you have a DMM?

A volt mod is pretty dangerous, and should only be attempted if you at least some what know some basic electronics.

Read the solderless volt mod guide. a soldering guide is the exact same down to the electrical tape (keeps solder from dripping on anything important) you just solder it instead of taping it down.
