QUICK 880m Bricking question?

Okay so i flashed the vbios on the 880m months ago and did some good benchmarks. I had a lot of driver crashes in playing some games if i pushed the limits. but I read that some peoples cards were being crippled after several driver crashes. i stopped overclocking when i saw that problem. now that a few months have gone by, has nvidia fixed the issue? can i go back to overclocking or will the card after a few more driver crashes be broken and perform worse than an intel igpu?

 

Nobody knows. Its possible that it wasn't even a driver flag and rather a hardware failure of some sort.

I wouldn't push it just to be on the safe side. Besides, these cards are impossible to keep in reasonable temperatures when running 993MHz 24/7, let alone when overclocking.

 

i just did a safe overclock and scored a p9400 on 3dmark 11 performance with the temps only maxing at 83. had a few driver issues though while messing with settings. just scared of not being able to game or brick it

 

Overclock is only safe because you're just benchmarking. I don't believe there is a stock machine out there that can dissipate the heat of an overclocked 880M over the course of an hour or two gaming session.

I would stop messing with it unless you want to be the guinea pig on whether or not the flag still exists. I got my old pair to 1153 core @ 1.1v but I won't be pushing these new ones at all.

When you start overvolting the power consumption goes up quadratically. Even if you can dissipate the heat from the core, your VRMs are now going to be sweating their (BGA) balls off trying to pull 170+W instead of the usual 110 or 125W. That's some seriously bad juju for the power circuitry if you run them like that for extended periods.

 

Impossible is a strong term

someone said sager has heatsinks over the vrms too to help cool them? im at 87.5mv in inspector and maxing at 83c. i have a 240w power supply giant brick. i want to push the card more but i dont know when to stop

 

You've likely reached the limit for that adapter. My 330W actually trips overload protection with anything over 1.087v with 3dmark 11 and turbo turned off on my processor, processor then undervolted by 85mv. I have an SLI machine but yeah, you are definitely going to be limited by your PSU at this point.

83C doesn't surprise me for a quick bench but if you ran Catzilla it would probably throttle. If it doesn't you have the best cooling system of any current Clevo because even the P570WM can't cool 880M when they have a hefty overclock and overvolt like that.
