Just register for this thread and to say thanks.
LtMatt bro really wanna thank you, the fps got and incredible boost.

im using the .850v bios, cos the "newone" does´nt work well for me, i just made 1 change (the 0.850v) and was the tdp, i took it to 220w , i can use 1200@1700 hitting 73 ºC max with 1281mv and power limit 10%, also i can take it to 1230@1700 with 1294mv +25% power limit and hit only 74 ºc, but dont really need this for 1080p

My 24/7 are 1180@1500 with stock voltages (1250mv +10% PL core -1600mv mems)
some bench´s with 1230@1700

So happy with this card, hope to get another one for crossfire, but first need to upgrade my processor :(

Great results. Looks like you have a good clocker. Glad it helped.
 
What's the airflow like in your case?

As a reference (and bear in mind this was only a short benching run) but I just ran a few benches of Sleeping Dogs (which apparently is notorious for drawing a ton of power and really heating up GPUs) at 1150/1700, 1.25V and +35 power. At 100% fan speed my top card was peaking at 74C. So with a decent airflow temperatures shouldn't be going anywhere near 80C with your settings.

If I'm playing BF4 at my everyday settings (1050/1400, 1.175V, +25) I see peak temperatures around the mid-high 60s during sustained gameplay sessions.

These cards really don't seem to like going above 75C so that's more than likely what's causing your crashes.

* should add I'm using one of the non-TDP adjusted BIOS from the first page of this thread
 
Are you running xfire.

I have a FD R4 case and Apache 120 front / Silverstone AP140 Front / 2 FD std 120s out the top / 1 TY 140 bottom and 1 side / 1 140 TY rear.

So plenty of air. the house is a hot house. Moving in a few weeks so should be cooler.

Its because hes running two cards right next to each other. You can improve things by removing any pci brackets around the gpus and having a positive pressure case. This forces extra heat out and is what i used to help keep temps down.

You can also use as many side intake fans as possible on the side of your case to give the gpu's more cool air.

I have all of them removed all ready. I have 3 x 140s and 1 x 120 fans intake. And 2 x 120s and 1x 140 fans exhaust.

I see you have sold your 7950s LtMatt.

Ah well not much more you can do then unless you decide to change the paste. I found it lowered temps a good few c as the paste jobs were terrible.

Yes my 7950's are sold and in transit. They will be missed but its time for something new to benchmark. :)
 
So decided to sit down and oc my system after resetting due to crappy mobo.
Have 2 7950 iceq in xfire have the latest bios flashed got the clock upto 1110 without upping the volts but every time i up the memory from stock the performance goes down?
 
Hi all, quick question, sorry if it's been asked before (the thread is getting quite long).
I'm planning to move my 7950 XFire from my main PC into my 2nd PC. The thought occurs to me that my 2nd PC only has a 750W PSU (Corsair TX750).
Is that enough to run crossfire 7950s?

I believe that each card can draw 225W, so that's 450W total leaving 300W for CPU and SSDs/HDDs, etc.
Now to me that seems like it should be enough but just thought I'd double check.

Thanks.
