AMD Radeon R9 295X2 Owners Thread

I added the fan I mentioned in my previous post to create a push pull and decided to just install the radiator at the back of my case after realising how much heat it outputs. Temps improved by 3C. After 15 minutes of crysis 3 gpu 1 was max 71c and gpu 2 was max 69c. From all the stuff I tried so far that game seems to heat up the 295x2 the most so far.

I noticed gpu 1 dropping from 1018mhz to 9xx at times. Is this the throttling? The 2nd gpu stays locked on 1018mhz.

What games or benchmarks do you guys use to test how hot the card gets? I am not too bother about the heat as it will be coming out the back of my case, but I would rather the gpu not throttle, as that may cause noticeable fluctuations while gaming.

Any tips are welcome :)
 
For me the hardest test I've found so far is Dragon Age Inquistion, running that at 1440p, most settings maxed, in Mantle with V-Sync off gets higher temps than anything else, even Furmark.

Normally seeing the core speed drop down a bit like that is indeed a sign of throttling but it should only happen when the temp goes over 74c I thought.
 
By the way, I was running crysis 3 at 4k with everything set on very high. Small set at 1x.

I am unsure if 4k would stress the card more and cause higher temps or not.

Yeah, I was thinking the same, if 71c then should stay on 1018 solid. I am on stock setting by the way, not attempted undervolting. I would rather leave everything on stock.

ok just had a little play

V -75
PL 0
Core 1018
Mem 1250

This is a single SP120 in push controlled by the GPU mounted at the front of my 240Air, all other fans in the PC are currently switched off

Graph is of a 3Dmark run Firestrike Extreme

How does this fair? is v-75 even a legit?
 
hi all

i used to put rad on the back of my case too rid all the heat it produced i had two sp120 fans the 0.25a ones not the lower ones at 0.9a split from the card never really got above 65 like that.

ive just chucked two 480 rads in a custom loop and temps are about 45-50 on load, if your heating up thats the way to go.
 
Well I bought the splitter and put it on the fans running off the GPU. Undervoled to a modest -40 at the moment. Need to play the witcher for some time to get a good idea, but it took much longer for valley to get the core to 74C. Interestingly the card doesn't spin the fans upto full - not in the same way as the motherboard does...shame really because they have much more potential. Will continue to have a play.

Can u use mobo fan pins and use software to control speeds for more fan speed

Looking into what gigabyte offer on my board.

Making progress though...7v cable with MB fan profiles set to maximum has brought my max temps down to 66C with my valley test...was hitting 74C when letting the GPU control them.

If I can control them via windows software then problem solved :)

Edit: yup, found some fan control software, set fans to 1700RPM which is an acceptable noise for me...temps seem good at the moment considering how warm my room is!

Edit 2: have put the fans upto 1800RPM, although probably not needed (can really feel the increased air flow out of the back of the case!). Heaven, Furmark, the Witcher 3 will not push temperatures anymore than 69C absolute maximum. Mostly hovering in 60s, and also dropping much more quickly once the load is taken off and also rising much more slowly when the load is back on. Not bad considering my room was 27C! Overall, very pleased (no more crazy temps and no more throttling!) :) - I should also add that the fans on the GPU itself don't go any louder than my two SP120s, so there really isn't anymore noise.

Good job captain. I might get those fans too, I like the way they look :)

No luck getting them to work properly with the splitter so the GPU controls the fans?

They look fantastic if you put in the red (AMD :)) plastic clip thing on the fan - I think it helps to direct the air. Mine came with blue attached.

The splitter runs the fans, but it doesn't spin them up enough to keep the card cool. With the splitter on I was hitting 74C quickly and based on the sound the fans weren't going above about 1300-1400RPM.

That cable won't do the job because the card itself has a 3 pin attachment with plastic surround, so the 4pin connection on that Akasa splitter doesn't fit (I learnt the hard way). There is another multicoloured one around that you can buy, but based on my experience I woulnd't bother.

I am tempted to get more of those fans for my case, but at the moment will save my pennies. Would probably get the quiet edition for my case. Performance edition is the way to go for the radiator.
 
My impression so far

Thanks for the info. Was considering just to get a better single fan and connect it to the GPU. Ideally need the fan to keep it below 70 so it does not throttle. That said when it throttled I did not notice anything when playing anyway.

Been playing some games single GPU mode and the games stay nice and cool between 45c-56c. I do not require more than 60fps so most games I will only need a single GPU anyway.

As for crossfire, played Crysis 3 with it and boy does it do a great job. Last time I tried playing that (on a 290) at 4k with settings on very high it was a slideshow. Now it is very playable and looks great :)

Tried witcher 3 with crossfire on with recommended settings, but the game plays better with crossfire off to be honest. Drivers are simply not ready yet.

Thus far I am happy with my purchase. Cost me less than a GTX 980, so even if crossfire did not work at all, it is good to have a water cooled 290x which stays cool and does not make noise. Crossfire is bonus when it works. Will be interesting to see if DX12 will help this card at all.

Overall great hardware, should have come with a 240/280 radiator to tame it and more work needs to be done on the drivers front to get the most out of it.
 
Well I have made the final big improvement tonight. Downloaded speed fan, linked both fans on the motherboard to the temperature on core 1 of the 295X2 (typically the hottest by a couple of degrees) and set a custom fan curve that tops out at 100% at 74C. What it means is when my card is idling happily at 38C (yes, my room is quite warm at 27C+ again), both fans are silent at 800RPM, and when under load, they adjust accordingly upto their maximum speed. Couldn't be more pleased...might need to adjust the curve to find a happy medium between heat and noise though :)
 
Anyone of you enthusiasts paired their 295X2 with an MSI 290X Lightning? Seen one on offer so considering picking it up for some extra kick when gaming at 4K. Not sure if its maybe a bit overkill for a secondary card or not as I can't actually find anyone to have done it online.

Also interested in how much power the setup would use as noticed the Lightning actually has more PCI-E power ports than the 295X2 lol, would not be overclocking it though, probably just overclock the 295X2 clock to keep up with it. Using a Corsair AX1200i.

Ah excellent, I was just about to post up asking if Speedfan could be used to control a motherboard connected fan based on gpu temperature. I think I've got a spare header I could use in the same way.

Im using an 290x lightning with an 295x2 and an 4790k with an rm1000.
Without any overclocking the power draw wont exceed 900 Watt from the wall.
In fact in most games stay within 700-800 Watt.
Games with great scaling such as tomb raider, bf4, crysis 3 Im using about 900 Watt

Thanks Oikopedofagos, does the Lightning still run at its full 1080 MHz clock speed paired with the 295X2? Or can they both be clocked independently? I've never tri fired anything with my 295X2 before so I'm not sure exactly how it all works yet.

I went ahead and ordered it anyway, theres another on offer (B Grade) for £200 in the clearance section on Overclockers UK if anyone else was thinking of doing the same thing.
