Hi

Im heving problem with over voltage my gpu.It gows to 1.212 max, i have the unlocked bios and in 3dmark11 im getting 1350mhz but voltage stay the same:-/
Is there a simple answer??
post #5272 of 7827
I have some questions since i'm new to the 600 series OCing

1. Is it possible to hurt your card with +300% Power limit and +100mv.(which is the max of the unlocked Bios)?

2. Can excess Voltage wreck the card before heat does from that voltage? (i'm used to OC ing Fermi cards where heat becomes a issue really fast)

No it is safe just keep checkig the temp and You should be fine.Mine temp never go above 70C but not on the normal fan speed of course:-) im heving problem with over voltage my card it is showing the max of 1.212v. For some reason:-/ in msi kombustor

This s the most active thread with a lot of info among you guys. But no one with the knowledge to figure this one out? Kinda stuck right now mad.gif

If you have the unlocked BIOS and are using Afterburner 2.2.3, then you are increasing the voltage. Software doesn't read the voltage correctly, so if you have the right BIOS and AB 2.2.3, then you'll see temps rise, guarenteed wink.gif

These cards stay pretty damn cool for a very long while. I remember my 570...I would set it to 950mhz @ 1.1v and do a 3dMark11 run and the card was into the mid-to-high 80C's. Now with my Lightnings, I can run 1430mhz @ 1.36v through it for a game at 99% load for an hour and only hit 63C. So, temps are much easier to combat than on Fermi, but as for the voltage...we've been told by Nvidia that the chips are very sensitive to voltage increases over 1.175v, yet of all the people here running way more than 1.175v, we've had no one report that they've fried/killed one of these from stressing it too hard, and these have been out since late June (about 7 months).

So, it's really up to you how comfortable you feel overvolting it. But I say that if you don't need to, then don't. But if you have a demanding game, don't hold back either. The chip will more likely than not out-live the warranty anyways. I haven't been pushing mine because I usually use SLI at stock clocks. But when I need one card for a game, and push it, it's still as stable as the day I got it, and temps are just as amazing wink.gif


Sorry arnie, no clue what's going on with that. If I had that problem, I'd be doing the same thing you are sadsmiley.gif

Did you do the MSI afterburner Voltage hack so you can increase voltage to whatever you want explained somewhere on the 1st page. or just get 2.2.3 cause i don't think you need to mod that one. someone correct me if im wrong

Do you mean that if someone has a LN2 F7/8 bios and overrides it with the A3 bios, this problem occurs? Because i have had the F8 bios at the card before i flashed it to the A3 bios.

No heaps of people have done that and nothing goes wrong. I'm not sure what he's saying about flashing LN2 with normal BIOS. I've done that too and everything was fine.

Since you seem to have semi borked your card but 3A works, why do you want to go back to the DCT bios for? RMA would be unethical since you did this yourself, but couldn't you simply flash the cards with stock 3A or modify the 3A bios to give the clocks you want and call it a day?

I don't think anyone here can magically fix your card for you. You cross flashed another cards bios to your card, it now has issues going back to the stock bios. You are using the same prog we all use for flashing, the flashing process itself works fine, but now the card does not behave properly with the original bios flashed back on. It's actually a quite mild side effect from cross flashing a bios, it can leave cards completely ruined. At least yours still works.

I know exaclty what you mean. And i appreciate the words.
I could offcourse stay with the A3 bios, though that bios will not work in SLI with any other bios. Even not if i flash my other card to the A3 bios.
Just like you, my other card can be flashed to any other bios with no problems.
My only thoughts now goes out to the SLI bridge chip. I've red that flashing a SLI setup could mess up the sli chip and i remember forgetting to take of the sli bridge once before i flashed (though still flashing with index --index=xx)
