For core I aim for under 80c. Also, have you ever run VRM's over 90c 24/7 to find out?
post #24362 of 38668
Yep. And that's why my sig says RIP Sapphire 7970.

95-105c 24/7 and 115-120c in benches cost me the card in under 3 months.

HOW JUST HOW Do you get it that hot?!?!

I have a Sapphire 7950 VaporX and a ASUS 7970 Matrix and none of them get that hot.

I don't think over 90c as an absolute max is too bad. Obviously 120c is hot though, that's like a 20/25c difference! That's massive. Poor card. Did you not want to step the card down a bit? Kind of asking for trouble.

Buy an accelero and you know why the VRM's get that hot wink.gif
Reminder again, we are NOT talking about core temps.

And no, cause I was under the same impression, thanks to a lot of people here, that they are ''rated for 120c''. Which is obviously nonsense.

People, our cards can operate up to +90º core/110º VRM...but then again, why would you let your card achieve those temps? +90º core means either two things:your cooling has gone to the cooling heaven/your cooling is crappy as hell OR you've cranked up core/memory mhz and voltage so much that your cooling can't keep with all the heat...also, your VRM are about to explode biggrin.gif

Which is a brainless achievement if you ask me. Between 70º-80ºC core it's were you hit GCN temp wall, and OCing headroom goes out of the window, as stability does.

Most cards have roughly the same vdroop. Custom designs like the ASUS Matrix might have less due to more VRM's but k.

When I refer to 1.300v for my card to do 1315Mhz core it's actual voltage is between 1.212-1.224v in-game.

So, if you want 1.200v actual, get a setpoint of around 1.280v.
Sapphire TriXX however, allows some cards (with a TriXX of 4.4.0 Beta or OLDER) to be overvolted to 1.381v setpoint which does correspond to roughly 1.300v loaded.
This voltage is not quite safe to run 24/7 though. The 1.300v setpoint is pretty much max you'd wanna run under air IF the temps of the VRM's hold up to it.

Oh, and here's some photo's of my ghetto Accelero biggrin.gif

Thanks. I'm just trying to operate within safe voltages. If 1.3 volts for most people is actually effectively 1.22 or so then I feel like I should tread carefully as far as aiming for a true 1.3 volts. The last thing I want to do is ruin my card trying to squeeze an extra 25 mhz on the core. When determining what voltages I can safely run at, shoud I be looking at anything else other than core / VRM temps? I assume nothing would be wrong with maxing out the voltage on my card as long as my temps are safe and my OC is stable.

Could my MB cause my card to not receive the proper vcore?
Just trying to eliminate causes before I return the card
