Crossfire 6950

Masterdeadly · 2 Sep 2011 at 07:43

Last question now before the purchase I currently only have 2 6 pin connectors coming from my tx 650w corsair power supply but I do have 4 molex connectors and I wanted clarification that these are molex connectors: http://www.mediafire.com/?9q49855rumud4ar if so should I purchase two of these http://www.overclockers.co.uk/showproduct.php?prodid=CB-018-AK to power the second 6950?

did you need to create a new thread to ask this? think you've already mentioned this in one of the other 3 threads you have going on the same subject.

you shouldn't need to buy the molex to pci-e connector as it should come with the graphics card(so 1 in the old one you have plus 1 in the new). as for is it safe to do I'll leave that to someone else to answer.

But the picture I have linked they are Molex ? and the adapters will work?

tommybhoy · 2 Sep 2011 at 09:31

Yes and yes.

As fowler002 said, check your original box as you will already have 1 molex to pcie adapter somewhere that came with the 6950, and you will get another 1 supplied with the new card.

Really no need to go to more expense if you already have them.

You will get more help if you keep all your questions in the 1 thread, I imagine folks will lose interest as they will have to jump from thread to thread.

I have just installed 2 6950 in cross fire and I have the same PSU. I did not need to order any more cables as the cards come with all the adapters you will need to supply power to your cards. You don't need to order any more cables.

Good luck.

Did you use the Molex to 6 pin connectors? So you used two 6 pins already from the power supply then used the 4 molex to convert them to 2 6 pin connectors?

Just seen another 1 of your threads:

1680 X 1050

Imo, you would be better off buying a new 1920x1080 monitor than xfire at 1680x1050. Doubt there's much use for xfire at your resolution.

There is only a few of games really: crysis, metro and possibly BF3 that you will notice a difference at 1680.

Fair enough the big numbers in the reviews look cool, but are you going to notice the difference?

Not right now probably not but I play Wow which is a hard game to run with 16AA etc but I always like to above 60FPS sounds pathetic but I hate seeing a game under 60 fps. There's definetly something wrong with me XD but I think i'm going to get a bigger monitor for christmas aswell

Masterdeadly · 2 Sep 2011 at 10:18

I'm going with a XFX 2GB and HIS 1GB ;D Will I connect both cards to my monitor or just one and I'm going to reformat my computer when Installing both 6950's will I have to run both driver discs through?

tommybhoy · 2 Sep 2011 at 10:43

Just the top card needs connected in xfire, get the latest Amd driver instead of the one on the disc as it will be an old one and you will need the CAP profiles too:

I would just plug in the new gpu then let the legacy driver install, reboot, install the new driver reboot again, install caps, reboot then you should be good to go.

Personally I wouldn't be doing a new OS install unless I really had to.

I dont know how to wipe my old drivers tho

Legacy driver install?

You don't need to, the Amd driver will do that for you, you just select install.

That's the MS driver that the OS automatically installs, before you install the AMD driver.

Masterdeadly · 2 Sep 2011 at 11:05

I see, looks like im all set, have the 650w power supply hopefully the molex 4-6 pin adapters reach

then boom 2 6950's

Witcher1979 · 2 Sep 2011 at 11:06

wow you will be set for a long time with those babies. Nice one

Masterdeadly · 2 Sep 2011 at 11:08

Do i have to enable crossfire at all in the AMD control centre?

tommybhoy · 2 Sep 2011 at 11:12

Yes. There is a check box for it.

Masterdeadly · 2 Sep 2011 at 11:14

Finally all my questions are answered

Ordering another 6950 monday, will I have to monitor temps on my CPU and GPU's now ?

Probably handy to see if your setup copes well enough with the extra heat.

Enjoy your new setup when it comes.

You know where to send the Deus Ex code if you already have it don't you?

Masterdeadly · 2 Sep 2011 at 11:30

By all means you can have it, the game doesn't interest me but I would like your steam or something so when I'm putting the cards in etc I can ask for some advise

Cool, one piece of advice would be to put the new card in the top slot as it's 2 GB. If you get a game that doesn't like xfire/sli then the extra vram may help with the extra eyecandy if you switch off xfire.
