R9 290X Owners Thread

Just ordered 2x 290Xs :) so I guess this means I'm back on the red team. Group hug? Do you have cookies?

I couldn't see how Crossfire 290Xs wasn't a great deal. It would have been wasting money not to buy them ;) heh.

Whoopsy. I've just ordered a 290X Vapor-X (peasant 4GB :p ) to Crossfire with my Windforce bought one year ago. My finger slipped multiple times and Mastercard let it happen.

I just wanted to share my excitemen... erm... news of this tragedy :D

Just praying my Corsair AX760i will be sufficient (with overclocked 4770K)?

Any news or benchmarks.:)

Yes, you've added my score already in the Firestrike Extreme thread. First thing I did once it was fitted!

I still feel guilty about a purchase that wasn't strictly necessary... but thankfully my satisfaction outweighs the guilt :)

Sorry I forgot about that one.:)

One 290X is good two is even better.:D:)

My PC decided to switch itself off after approximately two hours of playing Sniper Elite III. It refused to boot back up until I had disconnected one of my 290Xs. I had thought I was cutting it fine to Crossfire with 760W but I think I just confirmed it... new PSU required?

Computer boots up as normal with one card disconnected.

Does that sound like a correct diagnosis?

It could be as SEV3 uses a lot of power and produces a lot of heat on the cards.

Having said that check to see that your case is not getting too hot.

Isn't Crossfire borked in Sniper Elite III with Mantle, it only using one card?

So possibly when you switched to DirectX both cards were in use and the power drain became to much.

Just downloading SEV3 to test out Mantle CF but I think it is still broke.

We will have to pester the Red Baron (AMDMatt) next time he posts to get on the case.:D

It's not up to AMD to provide Crossfire support in Mantle titles unfortunately, that's not how the low level API works. All performance optimisations must come from the developer - and this includes adding support for multiple graphics cards. I'm afraid i don't know when it will be added and given the time of year, i would not expect anything in the near future.

What i can say is using DirectX works very well in Crossfire in this title, the scaling is immense. Currently playing it in Quad Crossfire at 4K maximum settings and it looks fabulous with x4 Supersampling enabled too.

If you use 3-4 graphics cards i recommend ditching the stock Crossfire profile and using 1x1 Optimize instead. Using this profile at 4K maximum settings will put you a long, long way ahead of any other graphics card multi gpu combination from any vendor.

The annoying thing about Mantle is AMD give the game devs something that will give them an edge and then the devs don't make the best of it.

I am not blaming AMD for this and actually feel sorry for them doing the hard work to see the game devs waste it.

Unfortunately this is why DX12 will be a run away success as the game devs will have to do the work writing for it or go out of business.

My 2600K bottlenecked my 290X's at 3440x1440 so I think a 2500K definitely would at 4K.

4K can actually make things easier for a 2500k

I just run this for a bit of fun using 4 x 290Xs @stock on Firestrike ultra 4K. This is an extreme example as you would never try this with 4 cards on a 2500k system.

In the first run I used my 4930k CPU as it is normally -

6/12 Cores/threads
H/T on
Ram @2400mhz
PCI-E 3.0 used


In the second run I turned things off to get the CPU to run as close to a 2500k as possible -

4/4 Cores/threads
H/T off
Ram @1600mhz
PCI-E 2.0 used




This is what I got (remember we are comparing graphics scores not the overall score).


4930k @4.0ghz as it's self

Graphics Score 10128

4930k @4.0ghz configured as a 2500k

Graphics Score 10056
