Crossfire two graphics cards - newbie help !

[H3R013]

Hi guys,

I'm thinking of crossfiring 2 AMD R9 290's I have. I was wondering apart from the actual graphics cards are there any other hardware items I'm gonna need.

My motherboard is Gigabyte G1 Sinper Z87 which I think is capable of crossfire and I have 8Gb of Ram.

Nope, install the 2nd card and crossfire bridge and hopefully the CCC will see the 2nd card load the drivers and enable crossfire.

 

[ShivP]

I thought crossfire does not require a bridge any more?

(What PSU do you have?)

 

[setter]

Your good to go providing you have a good quality psu, preferably 800w or above. No bridge needed with 200 series cards.

 

[RJC]

I thought you didn't but I mentioned it for good measure

You do not need the xfire bridge any more it is all done over the PCIE Slot.

750w Gold/Plat would be fine.

Yep, does look kinda weird when you see it and no bridge there. 750w gold/platinum should be ok as long as your not pushing heavy overclocks with increased voltages on the cards.

I am not the only one then , Some do look good, I think its the EVGA one looks good - not sure if its the SLI bridge!

Sorry to go extremely off topic here but seeing as you are a Forum Staff Member is there anyway for you to contact the admins? I sent two emails a week and a half ago with no reply. (was regarding a name change)

No probs, I will put a note in with a link to your post

Edit: done, but it might take a day or two

for psu I've got a silverstone 1200w gold - possibly overkill

So just to confirm I just stick in the second card with no bridge right ?

Also I have 8GB of ram is this good enough or is ram not a factor ?

 

[ShivP]

RAM won't matter, so yeah wack it in and go to CCC

The correct way to change your username is to make a thread in GD

I already tried that but the thread got locked because everyone starting flaming.

I have an OCZ 780W PSU with an 290 and when I tried crossfiring with another 290 the computer rebooted when I tried the Firestrike Benchmark due to lack of power. (Error came directly from POST) So I suggest an 800w minimum.

Also nothing in my computer is overclocked.

I got a 1200w gold silverstone although I would think a 780w should work with dual 290 but i guess it depends on power usage of the other parts too.

Not planning on doing any overclocking either m8 !

 

[H3R013]

also guys, what about the monitor. I have a 24inch dell ips and am currently using the display port connection with the 290 on the PCI-e 16 slot. Will this all stay the same or will I have to mess around with the second card's video output ?

Perhaps also slightly off topic, if you have two r9 290s, does the CPU not start to bottleneck things or does it actually improve gaming?

Depends on the cpu and what games tbh. There are a few, namely bf3/4, crysis 3 that benefit from an i7 chip with xfire/sli.

 

[Andygully]

An i7 would be preferable for xfire
