RX 580 crossfire problem

[sami.rysa92]

Example, in tests what I have read in internet this crossfire setup is capable of doing 100fps average on total war warhammer, but I am only getting about 40fps and I cannot sync leds within these cards.

cards are RX 580 sapphire nitro +
cpu ryzen 1600
ram 24gb

What make/model PSU are you using? Have you confirmed in AMD Radeon Settings or with an app like GPU-Z that CF is actually enabled?

 

[sami.rysa92]

Psu is Seasonic focus 80 plus platinum 850w and gpu-z says amd crossfire: enabled 2 gpus

What are your idle and loaded operating temperatures?

 

[sami.rysa92]

50 celsius and 34 celsius idle 68 cesius load and 41 load.

ps. sorry slow answer, had to do something. 😛

Exact motherboard model?

 

[sami.rysa92]

MSI X370 GAMING PRO

Are both displays connected to one GPU or does each GPU have a display attached to it?

I have one display and it is connected with one display port to my main gpu.

Ahh...I thought you were referring to multiple LED displays (monitors). Thank you for the clarification.

The second GPU does not seem to be heating up (meaning it is not doing a lot of processing).

Run the Superposition benchmark to see how well your system performs. See this thread for comparison.

I got score of 2576 and single RX 480 got 2406 ...so something is wrong 😀

 

[COLGeek]

Agreed. Only one GPU is doing anything and is what I suspected.

What motherboard slots do you have the RX580s installed in? The two reinforced slots?

Also, what types of storage devices?

umm... first and second slots... ^^'

Have you looked through the kb article at AMD?

Yep done that. Enabled crossfire and that logo also. I got that logo once when I was trying to benchmark total war warhammer and got that 40fps still.

You just using the default CF mode?

If you swapped the GPUs in their slots, does the performance change? Have you tested each individually?

I have not tested switching slots with them. Default crossfire mode?

 

[COLGeek]

Yes, there appear to be 6 CF modes. I assume you are using the "default". See the kb link we discussed earlier.

I got better results in warhammer (60-70fps) but not in superpostition benchmark when I changed CF modes.

 

[COLGeek]

You really need to try the swapping of slots to isolate where the issue might be. I would also recommend testing each card alone.

Ok I will test that and post results here.

 

[sami.rysa92]

Ok. So i tested slots and GPUs and results is... warhammer fps dropped to 30-40 fps with one card, but with CF warhammer gived 60-70 fps and superpostion gave same results (2576) with crossfire and with single card.

 

[sami.rysa92]

and both cards performs equally.

 

[sami.rysa92]

Okey... so can someone give me other gpu test program? because I think it is working with games like that total war.
