I have a question regarding my Sapphire R9 290 Tri X Crossfire. I Oc'ed it to 1150 / 1550 VDDC Offset 131.

I've ran Unigine Valley and it is stable but the score is lower than the stock speed. Is the top card throttling that's why the score is lower?

And also is this an acceptable temp?



I'm worried on my top card temp. VRM mas temp is 97c and GPU max temp is 91c.

Personally I wouldnt be comfortable with those temps. I know that they are technically safe (speaking about the gpu temp, maybe someone else can chime in with the VRM) and they are probably throttling. The tri-x's run pretty cool in crossfire if the case is well ventilated. I had mine OC'd, however I dont remember to what, but my temps weren't that high. Just back off the overclock, at the end of the day that heat/throttling isn't worth the maybe 1-3 higher fps.

My case is a NZXT Phantom full tower case. I have 2 240mm top exhaust, 1 140mm back exhaust, one 140mm front intake and 2 120mm side intake.

I don't know why my Tri X edition seems to run hot in crossfire. and the top card throttles with the heat.

Probably the best I could do is put my system underwater.

Playing ultra on BF4 and Titanfall Max gpu temp on first card is 81c and second card is 75c. This is on stock clocks 1000 / 1300.

To me that seems just slightly high for those cards, not necessarily high enough to think there is a problem though. The 290's just run that hot. Mine were overclocked and after a couple hours I would hit 85 in my old case, dropped a couple when I changed cases. So if you're hitting that at stock speeds its not a problem, just not very good. AMD claims that 95c is safe for the 290s, so you wont damage anything at 81. I dont think you have a bad card or anything it could just be restricted airflow, I saw your fan setup and it sounds fine, but you never know especially since these cards run so hot.

That's true but when I was just using only one card I never hit 80c. It is just the top card that gets really hot.

Exhausting all the heat from the second card to the top probably would be the cause because they are very close with each other.

I'm planning to swtich cases from NZXT Phantom to a NZXT H440 and watercool my whole system.

That would be your best bet, it's why I got rid of my tri x's, have 1 reference 290x right now, waiting for the second one, figured if I'm going to watercool them I may as well upgrade. Crazy thing is with my 290x, 100mhz overclock and a custom fan profile it has yet to go over 75c, sure it sounds like a jet engine, but still.

I've tweaked it again the temps are lower than the first post.



And I ran valley seems I got a 300+ increase on the score not by much.

Would you recommend if I watercool them go trade my Crossfire to 290x reference?

Those temps are better but the difference is pretty large. And yes, absolutely, reference boards ensure compatibility, also that way you're not wasting tri-x versions, you can OC them more, and the 290x is significantly better in my experience so far, and I loved my 290's. But not if you're only planning on getting 1 290x reference, it'll be disappointing coming from crossfire.

I'm planning to trade my tri x version to 290x reference cards. I would still crossfire them for sure. What reference brand is good for 290x sapphire?

Sapphire, its what I went with, I was told to stay away from gigabyte and..damn I cant remember, because they lock voltage so you cant OC as well. Just stick with sapphire, I have only ever had their AMD cards, never had a single issue.

Its not the only one, but it's the only one I remember, and can personally guarantee.

Would you consider a straight trade on my Sapphire R9 290 Tri X to a Sapphire r9 290X reference card?

Sorry but no, I literally just sold my tri x's in order to purchase my reference 290x's.
