Interestingly, I'm not getting acceptable FPS with Cryss 3 on Ultra running a 1080p display, so I had to drop it back to Very High setting. I was hoping to jack up the OC a little more to see if I can reach Ultra. Crysis 3 will saturate both cards.

Can you please share your volts and freqs to get that 75C limit?

Thanks.

I run 1200/1450@1.2v playing tomb raider maxed out and I get up to 77 when my ambient is high. Usually 90F+ outside.

But I have also used 120mm x 25mm fans, with zip-ties, threading them through the fins of the cooler over the back of the card.
There wasn't any sagging problem.

But, my air-cooling will soon be history, as I'm finishing a custom water loop for the 7950s: Warning: Spoiler! (Click to show)

Seriously, you should consider some better cooling for those cards. If you must stick with air cooling, look at the AC Accelero coolers, they work well, although the vrm sinks tend to be rather flakey for them. If you really want to do something about it, give water cooling some consideration. I put it off for years, then finally took the plunge. A couple good blocks like these:

you'll be hitting load temps. in the 40's. I'll have mine finished this week.

Think about it!smile.gif
i only hit 40s when i am at 1.4v though bios otherwise mine at load are like 37c biggrin.gif

loops looks great too btw

On my gigabyte WF3 7950 I have fans set at a max of 50%.  Right now the card is loaded mining, running at 69c max.  GPU:1050  Volts:1.150 Mem:1500

 

Oh and the ambient is 70f

My 7970 wf3 runs at 63c, fans at 50% and case fans at 50% too...pretty quiet all in all. Mining scrypt coins too.
Ambient temp is 24c, or 75.2F biggrin.gif

I'd love it if the new 8970 wf3 comes unlocked and without boost clocks biggrin.gif, and sporting the gorgeous 770 wf3 cooler.
post #27096 of 38668
okay, well it looks like I'm in the ballpark at least.

Thanks.
post #27097 of 38668
I just put in a EVGA 750w Gold psu and I notice that the input voltage to my 7950 is jumping from 12.06 - 12.13vdc under load. This is causing the VDDC to jump around and the AMP draw to jump anywhere from 40-100a. Is this common?

Attached GPU-Z showing all the spiking and jumping.

loops looks great too btw
Thanks. I hope to be doing the initial leak testing this week.
I wasn't meaning to push water cooling on Bradley, but I sure think he would enjoy the results, with his cards hitting 80C! And that's with good case airflow.

You've got an awesome build!thumb.gif The Komodos are great blocks, and I like the fact that they include the backplates. I had to hunt around for one of the EK backplates, with the extra shipping and duty, it really bumps up the cost. Main reason I went with them was the visible coolant in their acrylic top, as I have an IATX layout. But it seems that the Swifty blocks are damn good performers.

Your temps. are incredible. I figure it's pretty good to be in the 40's at load, but you're normally in the 30's! That certainly gives you a lot of headroom for kicking up the voltage. 1.4v. is a lot higher than I'll be venturing, but it's good to see that you can do it for benching.

It seems I am only able to get 1.225V @ 1100/1450 eh-smiley.gif

At least my temps are ok, usually high 30's, low 40's idle. Max under load is around the lower 60's.
