how did you pull that one off, going balls to the wall?
post #112 of 1336
probing with the GPU under load.. + too much coffee = shaky hands and bridged connection


..blew one of the mem chips..card is a paper weight now. I cant even salvage the caps off it..as they are all surface mount. Happy Thanksgiving

That sucks. There went some good PPD.

how many PPD do you think a 8800gt at 900/2250/1200 would get? that sounds about on par with a 9800 GTX+

sucks to hear CL3 but there is one thing wrong with your account of the matter...

There is no such thing as too much coffee.

GT = 112 SP's
GTX = 128 SP's ..thats a difference of roughly 3x shader straps..or 54mhz *3

...You could probably pull ~6.3k on the 353 WU's.. ~5.2k on the 787's..

This is what I did to a month old gtx295 co-op. Checking the voltage when a big noise made me jump, screen became a big jumble of weird colors just as the smoke came out of the card... Not sure what I touched.

Well i happen to have an gf6200tc and this is my first time trying to mod a card COMPLETELY myself without anyone having done this before in this card so here i am to ask a couple of questions:
AFTER MODING the FB i get 1,38 volts.Stock was i think 1,1ish volts...The pc wont boot with the card so i figured it might be OCP since this happened with my 5770 too and after lowering volts it booted fine.

So for the vMEM MOD i think like this:
In the first page of this datasheet:http://www.semtech.com/images/datasheet/sc2621.pdf
U ll see the 2,5vOUT.This is the vMEM of course...I am asking:should i measure the resistance between LDFB and ground?

For the OCP MOD should i solder on the OCS leg a resistor?

Thanks a lot!!!

post a picture of the PCB and the datasheet for the GPu controller we could be able ot help you with the OCP, I'd start a little lower on the core voltage.. maybe like 1.25??

for vmem you want FB to ground - pin 5 to 9, that's nearly the same mem ic as my 8800gt just a letter off
post #120 of 1336
@ Theo- FB is pin #5..measure from there to ground for vMEM
OCP is pin #4..measure from there to ground...raise resistance to raise OCP.
