HD 7950 OC'd 2013 benchmarks?

Hi all,

Just stumbled across this thread whilst researching overclocking my HIS HD 7950 iceQ Boost. I'm currently @ GPU Clock: 1100 and Memory Clock: 1500 with power control @ 20% using Catalyst.

When the GPU comes under load I get a very high pitched whine that seems to come from the card. I get no tearing or inclusions etc whilst benching the card and apart from this sound all seems well? It's not a loud noise, barely audible really just wanted a bit of advice from you guys :-)

Max temps so far seem to never exceed mid 60's. And I've got stacks of airflow in the case. I'm wondering if it might be the fan? It's not constant either, it varies in pitch wildly but is really quiet?

Anyhow, what do you think of the OC and power levels? Am I about to cook something lol I'm very new to this overclocking!

Cheers Guys.

It's coil whine from the capacitors. Pretty common and I wouldn't worry unless it's really annoying.
It may even die down a little with use.
Could try leaving it running Heaven benchmark on a loop for a while/overnight. That's helped a few people here.

Temps and clocks are fine. You've got room to take it further if the card's up for it :)

Thanks for the help buddy. I'll leave heaven running for a while and see if it quietens the caps down.

I think I've dipped in with the card, from what I can see it seems to be nicely clockable. Can any lasting damage be done OC'ing via Catalyst?
 
I've eeked a little more out of it now and temps are stable at 73'c :-)

In real world terms I've seen around a 400 point rise on Heaven and roughly 20fps on Arma3. When benchmarking in Arma2 (the most poorly optimised game in the world!) I've seen around 15-25fps increase. I'm chuffed to bits with this card!
 
BTW coil whine is from the coil not caps :)
Sounds like a very nice overclock there, its nice to get a good increase :)
 
Your allowed one every 3000 posts :)
Oh what clocks and drivers are you running and which 7970 do you have?
 
:D

MSI 7970 OC.
24/7, I run 1150-1250 (up to 1900 vram) depending on the game and if I can be bothered to change it :) I'll bench at up to 1340 at a stretch, more often 1300 tops. Depends on what the bench is.
Gone back to 13.6 as I was having a few issues, but I'm not sure if they were down to drivers. Gonna go back to 13.8 and see what happens at some point.

Very nice overclocker there then :)
I did hear someone else saying they had to back there overclock off with 13.8 so they went back as well. Unless it was one of your posts lol, not sure what I'm going to install when mine arrives yet.
 
It does help having it watercooled.
Even with a fairly insane aircooling setup, I could only manage up to about 1220-1250 for benching despite temps being good.

Matt had the same card, but his could do silly clocks with just an accelero, and there's another guy here with who can smash 1300+ with the bloody reference cooler :eek:
 
Well I'd be happy if I manage to achieve over 1200, it boosts to 1050, so I hope it will.
Someone always gets a great overclocker hey :)
 
No worries :)

Btw, I retract the 1340 claim after looking at the Valley thread which says 1325... Could've sworn I did though.

I had the pc outside the back door when it was -2c at least and valley only got the core temp up to 20c or so :D
