So I upgrade to this card from a pair of EVGA GTX 680 superclocked editions (2gig) in SLI, partially because I knew I would need more than 2 gig of vram for an eventual 4k upgrade. I was also "wowed" and taken by vairious benchmark analysis and reviews showing the 295x2 beating 780ti's SLI's in performance. Even the reviwes saying at load thier temps didnt even reach 70c.

 I have the XFX 295x2 and have the cooling mounted to the top of my case in pull config exhausting out. 

Wether its Crysis 3 or BF4, HWmonitor shows max temps always at 74c. This means the card is throttling. As well MSI afterburner shows clocks drop almost 200 mhz when this happens. ( I do not have the card OC'd in any way).

 I have a Thermaltake armor revo case with 5 intake fans and two exhaust. Case temps are not the problem.

 Here are my rig specs: AMD 8350 @ 4.7, Corsair H80i cpu cooler, Radeon R9-295x2 8gig, Asus M5a99x evo R2.0 motherboard, 32 gig Corsair Dominator ram @ 1866, Corsair HX 1050w psu, Samsung 840 pro 512 gig, windows 8.1 (64bit).

BF4 runs about as well as my 680 SLI setup, Crysis run 15-20 frames slower, same for Star Citizen Alpha.

Heaven bench and Firestrike extreme score higher than my previous SLI setup.

Anyone esle have similar issues? Solutions?

Make sure you have the power control in the CCC set to +20. Make sure you have your computer set for high performance and in the advanced power settings minimum processor speed set to 100%.

Turning up Power Limit rarely solves throttling, it may add to the heating up of the card which would make it worse not better. You should try reversing the flow on the radiator so its pulling cool air in. Your case may have great airflow but it's still warmer than the air outside.  Try that and see if it helps.

He said heat wasn't the issue. Setting the power slider to +20 disables the throttleing. It's real simple...put it to disabled and see if it helps....it is adjustable for a reason. You want to play games or surf the forums...adjust it accordingly. Being new to the AMD settings can be trying at times, as most of the default settings have to be changed. Here is a article on the power tune settings and why it should be disabled (+20) when playing games or overclocking.

Yes, power limit must be set to +20%, but isn't there a target temperature slider for that card to be configured as well ?

Are we reading the same post by him? Pretty sure he said its throttling at 74C which means heat IS part of the problem. Also these cards go up to +50%, and turning the power limit up CAN add to heat levels, I know that from experience on the HD 7970s and R9 290Xs specificially.

If I'm wrong and he meant is not heat then I'm misreading his post. This card throttles lower than any other R9 card (74-75C temp limit) and thats according to reviews not just me, that's as high as its temp limit goes.  Similar to how my R9 290X from Gigabyte has an 85C throttle temp in CCC.

His airflow may be great, but so is mine, and as a similar example, idle/load temps on my CPU which is H110 cooled did drop a bit when I switched it from taking air from inside the case to intaking from outside the case. It will probably have a more profound effect in this instance because it's a single fan radiator being put to the limit by two hot GPUs.

You should try reversing the flow on the radiator so its pulling cool air in

 

I would go with that.

Or, in any case, try to feed that radiator as much cooler air as possible.

There is a possibility, however, that the liquid cooler setup is wrongly seated and/ or has a malfunction.

In which case it should be returned.

What about the VRM temps? They are cooled by a standard design, and if they overheat, it would cause throttling.

Thanks for the replies gentlemen( or ladies I guess).

 I believe AMD recomends this card to be set as exhaust.

 No joke, at load this card exhausts hot air from the top of my case not unlike my wifes hair dryer on medium. That hot air isnt case heat, it's GPU heat. There is no way I'm setting the fan as intake, depite what ever cooler air it might take IN its still going to dump an ovens worth of heat right INTO my case.

I also dont think the blocks are malfunctioning as Idle temps would also be ridiculous. My idle temps are between 38-42c.

 Firstrike extreme maxes at about 68c (so no throttling). Heaven benchmark, Crysis 3 and BF4 all max out a 74c.

 I think the fan is too weak. The stock fan for this pushes about 50CFM. 

 There are other fans that push between 80 and 100 CFM....however this card uses a 3 pin connector which is controlled by the cards board.

 I'm worried that using a more powerful fan might cause a problem for the card.

 Thoughts?

Well. the fan speed can be increased..... but that will help only with the vrms.

Throttle means, your gpus are used 99% at a high temp like 80-90° C, then suddently the gpu utilization falls to everything from 99% to 0%, voltage status will decrease and the temp falls too.

That is the exact throttling behaviour of a gpu.

That is why power limit must be at max, and target temperature must be raised too ( i don't have that option in CCC so i could be wrong).

 

Disable ULPS as well.

Regarding the fan, I was not talking about the onboard fan cooling the vrm but the stock 120mm fan for the Radiator.

 The target max temp for this card is 75c and cannot go any higher. For this card, AMD has disabled any fan controls in CCC. The donly thing I can adjust is target power an voltage. I didnt touch the voltage but did set the power target to both +20 and +50. I also disabled ULPS and set the PC to performance mode.

 No change in heaven benchmark. HWMonitor still shows max temp at 74c.

 Could new drivers possibly fix a heat issue or is this purley a harware issue?

Drivers have indeed caused this issue in the past for certain cards. It wouldn't hurt to try a previous driver to see. be sure to uninstall the current driver before installing the new.

About the fan, yes. Long hours in front of computer can have that effect for me.

Sorry.

You should compare the cooling efficiency of your card with other owners on the internet.

It feel strange that it can easily achieve a temp of 74° C with a closed-loop liquid cooling.

If you see other owners of that card getting lower temps, then that means something is wrong with the pumps, the blocks, the thermal paste or whatever.

Or the chips have issues.

It means that you would have to return it.

 

edit:  it is actually a pretty good idea to test some drivers first, as stumped suggested, or even reinstall windows to be more certain for a software or hardware issue.

Man.......this is a Newegg purchase which means a 3 week or so RMA...(sigh).

Tried to install current beta driver (14.6 ) but my screen goes black and after reboot I'm still 14.4.

 Ill have to make another thread just asking 295x2 owners to post thier HWtemps.

 Thanks for all your help.....I really hope I dont have a gimped card.

You have to uninstall the 14.4 before installing 14.6. Try the 13.9. Uninstall current driver before installing the new. Installing new drivers

How about putting another fan on the radiator so its in a push/pull config?  May not help much but ya never know.  I think if you put the weaker stock fan as exhaust and the new stronger fan as intake it might help some though. 

From what I've heard, your temps are a bit high but not that abnormal. I would try the extra fan before RMA.

Good suggestion, but the fact remains that you buy a dual-gpu card for absolute performance and instead it gets easily throttled.

If it is indeed a case airflow problem, changes and additions have to be made to improve things.

You can try TheOnlyDoor to leave the case open and test for heat problems again.

If the ambient room temp is normal, and your case airflow is good, then it must be the card having a flaw, since your PSU is quite up to the task.

Isn't it ?

I am going to try that (opening up the caseon both sides) and seeing what temps it hits.

 My psu is a gold rated Corsair HX 1050w. I've measured the wattage from the wall, with this card in, with a Kill A Watt meter both on prime 95, heaven bench, firestike extreme and BF4 on a full 64 player server for over an hour.

The highest it ever hit was 820 watts and that only for a moment. It averaged about 700-780 watts at load. That should be pleanty of head room.

Yeah I opened up both side panels and ran the same tests. Still throttling at 74c.

 My thermostate sais my downstairs is at 76F (whatever that is celsius). It's summer time. That shouldn't matter though as far as QA for this card is concerned.

 I researched the model number of the Rad fan that came with the card at it pushes about 50 CFM.

 I ordered a 120mm fan from newegg that pushes 103 CFM...so we'll see if that makes a difference.
