Crossfirex 5850

12-26-2009, 01:56 PM

Hi!

I've been trying to make my 5850 crossfire work but it just doesn't. :/

The crossfire x option is enable on ATI Catalyst and everything is connected well...

Is there any other action I could take to test this?

You don't need to have Crossfire enabled with a single video card. That is for dual cards.

Yeah, Crossfire is for dual cards. You have one card in a PCI-E and another replica card on another PCI-E then you have a crossfire badge that will connect both cards, making it nearly two times as fast.

Just a reminder, if you connected a 5850 with a 4650, the slowest card will force other cards to scale down until it is at the same speed of the slowest card. Therefore 5850 will slow down to 4650 speeds which is considerably slower so I recommend you get two exact same cards for the best value and performance from crossfire

Crossfire doesn't downscale and hasn't done since the 4xxx series...
Alsol, is the OP trying to crossfire a 5850 to a 5850, or a 5850 to itself lol?

You all might have misunderstand OP's message, he might have two 5850's, he does say that the crossfire option is enable and all the connecters are "well".

If he ever comes back, maybe he can explain himself better.

If that's the case, I'd be glad to be of service....I have 2x HD5870 in CFX mode, no problemo.

Newegg is your friend.

I can find loads in the UK.
I personally have a Sapphire 5870 flashed and overclocked to 1050MHZ on the core and 1300MHZ on the memory.

Seeing as Newegg is out of the question for me as I am also in the UK would you mind telling me where you are able to get the 5850, sapphire preferably.
I have been looking for a while and all are out of stock. This GPU is the last component I need before I can get my first build running so any info will be very much appreciated!

Really that is too bad because at Newegg Saphhire 5850 are $299 but even better if you need a power supply or just want on for free get the combo and you get a 600W Thermaltake PSU just for asking for the combo!

http://www.newegg.com/Product/ComboD...t=Combo.310962

1.
Sapphire Tech 100282SR:
$299.99

2.
Thermaltake W0388RU:
$69.99

Combo Discount: -$70.00
Combo Price: $299.98

Shipping for me is $5.99.

If I had $300 I would be getting this.
