Msi 7970 Oc bad overclocker

[fluidz]

Received this morning.. Bought it in the Ocuk £299 sale. I've just run it through furmark , default burn in benchmark, and the temps are hitting 82c! My windforce only ever topped 73c allthough i had to rma it due to a faulty bearing on the fan. Tried pushing 1125/1375 and it's artifacting in furmark, i can see black spots appear, temps are hitting 87c! Gpu-z asic reads 63.1%.. Landed with a crap card methinks Default volts in afterburner reads 1174v.

Also overclocking doesn't work with afterburner, just doesn't stick after reboot. So using Trixx. Drivers 12.11. Any suggestions?

That's about right, the default fan profile is silent but lazy. Furmark also heats up the card to unrealistic levels so you will see higher temps running it. Use Unigine Heaven benchmark instead.

If you don't keep temps under control when overclocking a 7970 then you will see artifacts.

Depending how well your card resorts to heat, try to keep it under 80c for mild overclocks using a more aggressive default fan profile.

For extreme overclocks 1200+ core keep it under 75c.

I think its a bit early to call it a bad clocker, you need to learn how to keep it cool first.

Cheers for the reply, i'll try setting a manual fan curve using afterburner and report back. 100% = pc begins to levitate.

Hehe yes i know at 100% its loud.

I have the same card as you, i drew up some various fan profiles for fellow 7970 reference users, try using one of these and see how you get on.

Pick one depending on how much noise vs cooling performance you want.

If you need any help, just shout.

Fluidz, what's the max overclock you've been able to achieve and what did you set voltage at?

Applied your medium overclock fan profile and it's keeping temps in the lower 70's, thanks. Allthough, at 1125/1375 i'm still seeing black spots in furmark. I don't see them at stock 1010/1375 .. Do you advise I up the voltage to even achieve 1125?

I'd advise increasing the voltages slightly. But would first advise not to use Furmark.

Stop using furmark, its not an accurate way to find stable clocks.

Use Unigine Heaven to test for overclock stability. If it crashes or you get a driver reset, up the voltage one notch until its stable.

Then bump the clocks again, rinse and repeat.

Once youre happy with this then start testing by playing games. If you get a crash or a driver reset, knock the voltage up another notch.

Good games to test stability, Crysis, Sleeping Dogs, battlefield 3 etc.

Don't forget to put the power slider at +20%.

I'll take your advise. Will run it through heaven from now on. What preset should I use in Heaven for a realistic simulation of high end gaming, such as playing bf3 max'd out?

furmark should be banned imo,far to stressfull for a gpu

As said, never, ever use furmark. That software is spawn of the devil.
I just run Heaven at default settings to test my cards, worked a treat so far.

I edited my post a bit, report back sir.

We'll get you a good overclock out of that card yet.

High temps on the 7970 can causes crashes, at this stage more voltage will not help. All you need is to keep the card cooler.

The only reason I used furmark is because with my previous 7970, if overclocked too high, it would artifact in bf3 when max'd out, but for some reason would always pass heaven. The artifacts were replicated in furmark.

Default, as in tessellation disabled? There's so many people using different settings in heaven it's difficult to know which one to choose. I suppose default is best.

Use these settings to give your card a nice all round workout.

 

[humbug]

Please don't use Furmark / MSI Kombustor <- Same Thing, they are potential card killers.

This seems to imply you're running at 1125/1375 at stock voltage. My Gigabyte can't even do 1060 on the core at stock voltage, so I think you've jumped the gun a bit in saying you've got a bad overclocker.

Passed on 1125/1550

I'm going for 1200/1600.

I have haven't I.. What have you managed to push out of your card?
