I think he was referring to a max 24/7 overclock for gaming. LN2 numbers are "neat" but have no real world use and are rather pointless.

Not to imply that you are, Balsagna.
Anyway, I personally couldn't push my card past 1070 MHz core no matter the voltage.

I run OCCT for a minute or so to test for errors and stability. If it can pass that I've never seen a game crash. Rather pointless to run OCCT for long periods of time like some people do. It puts far more unrealistic stress on the GPU than any game would at max usage. So there is no point in lowering your clock further and further just to meet long-term OCCT stability if you are going to be gaming.

Gaming? Perhaps.
GPGPU? Not so much.

I run DC programs like Milkyway@home and it's really heavy on GPU resources.
Having even the "slightest" error will lose me points. wink.gif

Thanks for that.

The good card that I can get to 1200/1600 easily is 74.9%. The card I can't do crap with is 84%.........

Well my clocks usually happen like this in OCCT -- 1200 with any voltage, it'll freezeup and lock the computer for a hard reset in a matter of seconds. Dropped clock down to 1175 with same voltage, same thing. I needed a hard reset. I dropped voltage a tick, it lasted longer, dropped voltage down some more, it lasted longer. I don't mind a couple errors if it lasts for 30minutes without that many, it's most likely stable.

In my case, I got 10,000+ errors and it was just a matter of a couple of seconds before my computer locked up. I think I'll back my clocks down to the 1125/1600 so I don't need very much voltage and it's rock stable (I think) I just lose about 4fps and that's about it.

Dude you need at least 10-15 minutes of OCCT for stability. Just cause a game doesn't crash doesn't mean ur stable.

The only way around that would be to disable PowerPlay.
Which leaves me kind of curious... Does anyone else suffer from the black screen of death when overclocking high and stress testing?

That is a feature; AMD intentionally throttle OCCT thru the drivers so you can't kill the card.
post #3319 of 38701
ok i dont understand the acic stuff mine says ASIC quality 66.9%...so now the big question *** IS THAT ???good bad regular ...?? what i can do with that ??? what clock will be my max on air ..idk....
post #3320 of 38701
Ignore it. There's no pattern been determined for correlation between ASIC quality and max oc.
