It's for cards with the CHIL chip. 'The way mentioned here, might work on all cards using the CHIL 8318 chip, which is ASUS TOP cards like 670 and 680, MSI Lightning 680, EVGA Classified etc., but my test is limited to the Gigabyte GTX 680SO (GV-N680SO-2GD).'
Well seeing as how my cards have reference 680 VRM's I'm not going to risk it they will do 1320 on firestike I'm happy with that. Good luck guys I will be checking back to see your results.
I've only seen that chil chip on non referenced PCB cards. If I'm not mistaken, the 670 FTW is on a reference 680 PCB. I could be wrong. Try it, the only thing you'll loose is a couple mins of your time if it doesn't work.
I may try it when I have time tomorrow I have plenty of thermal headroom but I don't think I'll go past say 1.25V as it is a reference 680 PCB.
My ex.(did not die) 6870 @ 1080 MHz with 1.4v air using the other msi hack that was banned. http://www.3dmark.com/3dm11/6308380
Using the full hack, and version 7.39 of art money. 1372 seems the sweet spot for 150% power, see my 1450mhz OC throttle as the power is maxed during another firestrike>>
Only way around that throttle is a hard mod. And unfortunately you cant do "old school" modding on the kepler cards like you could on previous cards. your going to need a whole different power board.
The first part of the trick (just editing the afterburner .cfg) raises the voltage to 1.3v so you could perhaps try it, if it's a good idea or not i dunno, 'CHIL voltage regulator hack' would have been a better thread title.
I guess this isn't really needed if you have hotwired the cards? any higher on the voltage my cards crap out and my display has massive artifacts lol
The first part of the trick sticks after a comp restart (the 1.3v), however the second part which unlocks the 1.4v doesn't stick and needs to be applied manually. anyways i'm gonna keep the 1.3v that can push 1372mhz and be happy. cheers folks.
I could of got the classys, did not due to the evbot being removed I did not get them, oh well, enjoy guys
