How thick are the cards>

Sapphire Radeon HD7950 OC 950MHz Edition

Is it possible to run them in a multi gpu setup (3-4 cards), without fans hook into the card next door..

I use to have spacers between the cards..

are they 2 slot high + or - some??

Goin to place an order for some gpu's soon..

I'll measure mine when I get home (a few hours) if no one answers this more quickly. They're dual slot cards and I would think they would work fine right next to each other. You'll need good airflow though if you OC. I've got 2 and they can noticeably change the temperature in my living room.

Thanks for the fast reply..

Circulation is no prob..


Is it unlocked manual ram voltage control?

Some of the supposed dual slot cards, are dual slots, + some..

Thats why i am asking..

And the xtra +, cause probs in my setup..

Never owned Sapphire..

I'll vouch for Sapphire's build quality. I've put several dozen (probably over a hundred) of them into various desktops and workstations over the years. Never had a single DOA or failed card.

As for the 950mhz editions, like all non-reference cards that dump hot hair into the case, heat is an issue. I'm currently working it out, but my top card is getting too hot during overclocks under games like Metro and/or benches. For me it is because recirculated hot air is trapped between the cards. I suspect that this is due to the hard drive cage being so close to the end of the card. I'm hoping that removing the unused PCI plates, increasing my positive pressure, and taking a dremel to the HDD cage will help that. If you have good general airflow this shouldn't be an issue.

For the record, I use triple spacing (sabertooth mobo). For me it's clear that the issue is stagnant air because my CPU temps haven't changed at all and my lower card runs a good 10-20c cooler than the top card. Another thing to note is that these cards tend to have relatively high ASIC quality scores (89 and 87 for me), so they run at lower volts stock, and may not be the best cards for water cooling. It's on the "modified" 7970 reference PCB though so power delivery seems a tad overbuilt (and you'll need 1 six-pin and 1 eight-pin PCIe power connector for each card). I honestly haven't checked to see what the max volts Trixx will allow me is, as I've only really flirted with OCing them.

Thanks for the reply..

Yes, the top one, is warmer, But when really OC, and maxxed out.. Even the lower one gets very varm..

Will do a little research on these gpu's..

Or it will be the Twin Frozer III Again..
