Hi,

I recently bought a second 7970 from powercolor, but found out my card doesn't have vrm heat sinks and not have reference pcb. Should i be worried? I also heard it would has crossfiring issues with cards with other brands. I also have my sapphire radeon hd 7970 100351SR, worried that it will not overclock well with my build, or will have crossfiring issues. Would really appreciate with some advice from our members.

I also dont mind if i have to install heat sinks or accelerator coolers on my cards, knowing that would be the best thing to do to insure my cards for top safety and overclock-ability.

( I have my powercolor hd 7970 on my friends computer,as a gift, will go put it in once home)

My specs:
msi z87 g41
core i5 4670k
seidon 120m
corsair tx 750w v2
sapphire radeon hd 7970
powercolor hd 7970 v3

Thanks, i was also looking at the accelero cooler for the powercolor card, is that good choice?

And any word for the problematic crossfire?

And thanks for replying this fast, you're awesome!

No problem. As for crossfire, they can be crossfired with other brands, I personally would use 2 of the same.

And yes, that is a really great cooler.

Be careful with overclocking.

First of all, it's a good idea to clock each card to the same frequency. So if one card was stock 900MHz and the other 960MHz if you decide to overclock maybe just bring the 900MHz up to 960MHz and leave the default 960MHz one alone.

Some card overclock well but some don't. Personally, I wouldn't overclock at all or very much and then just enough to get the same frequency as I mentioned.

*Don't forget Crossfire drivers have improved but DX9 games and some other scenarios still suffer from significant microstutter or often RUNT frames on the 2nd GPU that give a perceived 30FPS experience even though FRAPS reports 60FPS.

Thus you should DISABLE Crossfire for DX9 until support is available with improved drivers.
