7950 OCing worth it?

post #1 of 10
Thread Starter 
Is OCing to 1100/1400 @ 1.175 V, from my normal 800/1250 @ 0.925V, worth the performance boost, but at the cost of higher power consumption and temperatures?

My temps with my HIS 7950 IceQ (Blower style btw)

Maxes out at 800/1250 @0.925V at 67 degrees with 40% fan speed (Which is basically a 5% fan speed difference from idle, and almost silent), while the higher OC maxes out at 80 degrees with 60% fan speed, which is significantly louder and noticeable. Is the performance bump really worth it?

Cheers,

Totally. Unless you play games which peg your CPU to 100% per core they use.

^^Yep.

It makes an immense noticeable difference for me when I up the core to 1150Mhz.

i played most of my games maxed (BF3, C2 . . .) with the 7950 stock (900/1250) but my i7 was/is oc'ed to 4.5. C3 at High and 4MSAA. now, i use the same settings with a 7970 and can't see a difference.

By going from 800 MHz to 1150 MHz is like owning a new card.
You will notice between 35-40% performance increase.

Cheers! I'll keep it pegged at 1100. I can hit 1200 at 1.275 V, but thats way too much for the Stock IceQ cooler (And to think the stock voltage is 1.25V on these, I had to change the bios to a 7970 one just to voltage change), and I was hitting 85-90 degrees at stock volts when I first got it. Ultra Pro brought it down 10 degrees, which was nice.

What do you guys think is a safe operating temperature for a 7950? Assuming I game around 1-2 hours a day. I'm happy to let it run up to 85-90 degrees, provided its safe. By configuring my fan setup, if I make it hit 60% at 50 degrees, it'll bottom out at a temp of around 72 degrees, while if I let it max out at 60% at 80 degrees, it'll stay at 80 degrees. So right now its maxing out at around 70-72 degrees in Crysis 3.

I would keep gaming loads sub 80c.

Keep VRM temps low as well. Core temps should probably stay below 80 or 90, but you have to keep VRM temps low as well. For me that means my core temp shouldn't go much over 70.

My cooler has a very nice VRM plate, according to GPU-Z, it doesn't surpass 60 degrees, and its blower, so that works too.
