Weird problem with the XFX 8800GT

post #1 of 3
Thread Starter 
Yesterday I did a voltmod on my XFX 8800GT (non-reference). Using a variable resistor of 1K Ohm, set on max resistance. When I booted my PC I read the vGPU had 0,800V. Way too low ofcourse so I didn't post. After that I adjusted my resistor, and when booted it was 2,2V !! So I immediately turned it off (I saw smoke ).
I removed the resistor and booted again. This is the weird part, the voltage was stuck on 0,750V while it should have been 1,1V. So there was no way to run my card. So after some calculating I discovered 0,495 Ohm would give me 1,1V and so it did. I was able too but up just fine, games run fine and stresstest with ATi tool for 45 minutes stable.
But every time I remove the resistor it drops back to the 0,750V.

What could have gone wrong? Some sort of protection on the card that enables this?

Thanks in advance.

BTW.. It runs on 1,25V now stable.
