8800GTS 512Mb (G92) vMods

500ohm VR will make it a little less "jumpy" when adjusting over ~1.35V.

When you're using 1K VR you have to be more carefull turning the pot cause a little dial means more voltage than with a 500ohm over ~1.35V.

I did set my 1K VR to 500ohm before soldering so a 500ohm VR is even better than 1K actually.

How much core clock do you get with ~1.35v ? At what point do I need OVP mod ? Im about to search for it but could you point me to the OVP mod ?

I think it depends on your cooling, anything over ~50ºC isn't stable for me, i'm waiting for my waterblock to arrive so i can get temps to decent levels, mine idles at 58-60ºC with the stock cooler, stock volts.

In a cold ambient with 1.35V you should see around 850 core i reckon.

Overvolt protection kicks in around 1.6V so unless you're planning to go xtreme there's no need to mod for that.

Cool !!

I wasnt planning to go that high as I dont really want to fry it up , but a little vmod fun wont hurt

I am planning a two stage mod with a small jump for 24/7 use and a large one for benching . I had this on my last GTX and it worked well . My G92 games fine at 800 core so far and benches up to 820 , so I hope I get more than 850 at 1.35v.

So here is 850 core 2100 shaders with 1.35V and stockcooler fan at 100%but becomes unstable over >50ºC:
