[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 1578

post #15771 of 38701
I just received my 7970 on Monday and I noticed there is an extra option available in the CCC that wasn't there on my 6870.

What is power control and what does it do? Is it necessary for overclocking? I am able to max the OC limits in CCC no problem.

Max it, just max it. It is powertune and it controls the maximum TDP of the card. Essentially it limits the power draw. When would you be in a situation where you would hit the power draw limit? Overclocking, so raise it or you will hit the limiter spoiling all the fun.

Ok now that would have been a great feture on my 6870. Definately going to make use of this.

Thanks for the explination.

post your results in this thread with overclocking . Even with stock voltage overclocking you can hit 1.1 Ghz on most HD 7970. you might need to control temps by manually increasing fan speed or setting up a custom profile in sapphire trixx or msi afterburner. try to keep temps around 65 - 70c in games. do not bother with furmark or other power viruses. use heaven, bf3, crysis 2 for stability testing . thumb.gif

Really?!!?!?!?


I got a Sapphire 7970 coming in tomorrow or Friday. I'm hoping I can hit 1ghz on the stock voltage biggrin.gif

Picks up rock from wermad's back. Almost all 7970s will do 1ghz on stock voltage. You'd have to have a very unfortunate card not to hit that.

I'm been sick like a dog lately (lung issues frown.gif ), so I haven't researched the 7970s oc'ing potential tongue.gif

I've had four 7970's so far and they all did 1125MHz on stock voltage. One of these Sapphires will do 1175MHz on stock...

Just curious, all those cards that did 1125MHz on stock voltage, how much was the memory clocked at? I'm running 1050/1500, once I do 1100, artifacts starts to show.
