Ask one of the Senior Moderators if they have any contacts at Sapphire. It's not what you know...

Im bit confused now about voltage of my 7950 as all programs seems to give different readings. Powertune is setted to +20 so it shouldnt throtthle or anything.

Afterburner says stock voltage is 1.031v and reads same under gaming/burning at sensors

GPU-Z sensor tab gives anything beetween 0.990v and 1.021v at load.

HWinfo64: says 1.020v

Then when i lauch furmark it says 1.090v

confused.gif

If you haven't unlocked Unofficial Overclocking in AB then try 1125/1500 but change voltage to 1.150-1.175v and see if that helps

AB reads 1.112v when I hit the reset button, so that should give me headroom up to 1.237. I'm not too worried that I can handle 1125 on the core, more that BF3 doesn't crash on Ultra. I will run some tests on 1125 core and voltage up to 1,22 with Ultra settings enabled.

Would it be possible to cool a 7970 with a Corsair H80? Would the waterblock outlets fit the H80 tubes?

 

Thanks.

Dumb question:

I'm going to reapply the thermal paste on one of the cards, if not both since one of them runs 5-10c hotter than the other. With the hotter card on top, the gap is 15-20c from the bottom card with a higher max temp. With the cooler card on top, the gap is 5-10c with a lower max temp, so I want to check the thermal paste on the hotter card.

Is it as simple as taking off the screws and using isopropyl alcohol to remove like a CPU cooler?
Is the GPU chip the only thing that needs thermal paste?
Can I use regular CPU thermal paste like a tube of Noctua NT-H1 thermal paste?
How difficult is it to change? Easier than replacing CPU cooler?

I've never taken apart my GPU so I don't want to mess things up trying to take it off and putting it back on.

Do not, I repeat DO NOT take apart the card unless you are water cooling it.

The default paste they use isn't some zinc crap, it's a phase change material designed to work with the cooler. You can't buy it in the shops, and people have reported shocking rises in temp from changing the thermal material to AS5 or similar.

You know that when you have cards in CF/SLI the primary one runs hotter right?

Anyways, you could still re-apply the paste if you want (they usually pour it on).

Look up some disassembly guides/videos of other cards. Its pretty identical.
The VRMs and RAM need thermal pads usually (they come with them, be careful not to tear/lose/ruin them).
Maybe, but I haven't investigated that.
Lots of screws, stupid retention brackets, but nothing outrageously difficult. Its more difficult than a CPU cooler though.

Watch lots of videos if you really want to do it.

He sounds like he's done more research on this. I wouldn't do it simply because its too much work for not enough benefit. I don't know if this holds true past the 6000 series, but graphics cards can handle 100C+.

Hooray! I found my issue! My 7950 was broken! biggrin.gif oh wait... frown.gif

Yeah, I swapped in the other one and it works perfectly. BF3 ran first try (beautifully).

Dammit all to hell, now I gotta send this other one back. At least I didn't put the block on it yet rolleyes.gif

Sadly... You can't really give it the voltage it needs (I think) without having OCP kick in at those clock speeds.

Found the way to set higher voltage and Furmark and OCCT doesnt turn off the card with OCP... set Powertune to 15% and no more blackouts!
Watched throttling while these test were running
In OCCT Powertune throttles clock only at begginning of test the rest of test throttling doesnt occur
In Furmark throttling occurs all the time

BUT CARD DOESN'T POWERDOWN

Anyway, I hate this fan and its sound... leaving voltage at 1.175V
