Bad performance/Usage spikes with R9 290 Tri-X CF.

What driver do you have installed? Do you use vsync? I have two 290x GPUs and run 1440p on 2x ultra settings vsync at 100Hz and get a pretty steady 100 fps with the 14.4 drivers.

No V-sync and first 14.4 then 14.7 same result.
 
Just my thinking. I was using 14.4 and today i installed 14.7 beta. Got the same result.
Hmmmm...

This is quite odd...

Might I ask what settings you have turned up on crysis 3?

It's really weird. I turned up all settings to max and 8xMSAA. But when i turn it down the framerate stays the same.

I am almost convinced something else is causing these issues because I cannot find places at least within the last couple of months stating issues like this as most reviews, forums, etc are reporting just fine and my system is performing well.

Just out of curiosity (Im just trying to eliminate things) have you checked the temps on your 2600k? I see your running a stock cooler and im just curious if something is amiss and your getting some throttling somewhere (Because spiking performance is indicative something is changing and holding the system back).

Re install latest whql from here or Amd's support page.
I have had absolutely terrible times with latest betas and rc's. Rolled back to 14.4 a week ago. Higher temps on average of 8 celsius on my card with anything past 14.4. Have you monitored both gpu temps while playing? Is your psu having trouble reliably running the cards? Hmmmmmmmm.
 
Does anybody believe THIS, might be the bottleneck?

Also, the 290's are not supported on the ASRock site...not sure it matters.

Probably not worth 2 cents...:p

First of all, i must thank you for helping me.

My temps are "fine". The hottest core is about 75C.

Together with my cards i bought a Sound Blaster Z. Do you think the sound card can cause this problems?

Pretty interesting, not really sure what this does though.

The hottest card is 75C maximum. I had the same problem with 14.4 as i have with the 14.7 beta. I have heard that the HX750 can push out 900W so i really think that the HX850 can power this card properly.

If im thinking of the right sound card it plugs into a PCI-E 1X slot. Your CPU only supports up to 16X PCI-E lanes (20 but 4 are used by the system) but I would not think that is a problem overall.

You might try removing it though and running off integrated to see what happens.

Do you think that there is a slight chance that it is the Sound Card that is causing these problems or are the chances of that almost non?

Well in all honesty I would say there is a decent chance because the way PCIE works would cause if you exceed the number the CPU can deliver it would drop down the slots to a lower size. So if your running at 8x 8x on the GPU's your not going to drop by one, its going to drop down to the next lower setting (4X) which maybe the cause of the reduced speeds because 4x on medium-high GPU's is well known to cause some bottlenecking.

However it will depend on the slot because the 1x slots are normally linked to the chipset where as the 16x slots are linked directly to the CPU (Because GPUs are OP and need the speed). Based on that I would guess if you have it in the top PCIE 1x port then you should not be having problems but its hard to tell as wierder things have happened.

I would say its worth a shot since you bought all at the same time. But I would not say its a definitive "Yes". But if nothing else it can help eliminate potential problems (Or rule things out) which can help lead to the answer. The problem is something is obviously holding the cards back from performing properly.

Is there an in game setting that ati is horrible at rendering? SSAO? Advanced physics? And the like. I know were talking 290x's here but those features in some games kill my 7870 and hard.
Are you using Mantle or Direct-X?

I will get back with results.

290 Tri-X, not 290X :P But i have tried both with no effect.

No difference at all without the Sound card :(. 28-30 fps on Crysis 3 and 38 at the exact same spot with CF

Dang well it was worth a shot...

Do you have GPU-Z and could you provide a screenshot of GPU-Z showing what configuration both 290's are running at.
 
Well everything seems to check out on the charts, AMD cards on idle show up at 1x on the PCI-E interface...

Well this is getting interesting...When I get home ill double check my 290X's are running properly on BF4 and Crysis 3 at 1080p (Ive been playing BF4 at 4k so I would be shocked if something changed in an update at 1080p).

Another thing is if you can give the same GPU-Z screenshots while the GPU's are stressed (Gaming or what not) so we can see if certain things are running at the correct frequencies and such.

Im trying to think of all possibilities that can cause this left.
 
Id say use DDU. Take out one of the cards. Install the latest AMD driver and test with only one card in the computer. See if you get better single card FPS.
+1

Yeah this is really wierd. I will give you the results when i get home from work.

Of nothing else work i'll try this.

I have looked at GPU-Z and it all look fine except for the spiky GPU usage on one of the GPUs.

Could you do another picture while the GPU's are being stressed of GPU-Z
