AMD Radeon R9 295X2 Owners Thread

I think it was man!! I did not increase the voltage to the cards no need. But one 2000w PSU did it easy.

I think you may know this.
is there any way how to put more volts to the card with MSI afterburner?
It only allows +100mV while Sapphire Trixx allows +300mV I believe.
Do u know something more(how to modify afterburner) mate ?

Anyone tried running 2 295X2's on an AX1200i PSU? I was thinking about getting an extra 290X for 4K gaming in trifire but am wondering if I can get away with an extra 295X2 in quadfire instead.

I run 295x2 + 290X and VRAM seems to be more of an issue than GPU grunt with these cards at 2160p. I never really see 100% load on all GPU's but often see the game wanting more graphics memory than can be delivered.
 
Are you still using the stock cooling Mrkambo and if so what temps are you seeing? I could bench at similar settings on mine but in some games, especially Dragon Age Inquisition, running at 1440p after a while I started to get throttling due to hitting 74 degrees

I'm using stock cooling, change the fan to a corsair sp120 quiet edition running at 7v instead of 12v and its set to pull air through the rad, and is mounted to the front of my 240 air, and tbh I've seen it hit 68/69. I'm also at 1440p but I tend to turn vsync on just to keep it controlled, the stock fan is rubbish that **** needs lobbing out!
 
2 times 295x2 (puny I know compared to above), Corsair sp120s mounted on the front of the radiators with stock fans left in place blowing through, sp120s pulling through, 3 pin y connector to connect both fans to the single graphics card so they run same speed, Crysis 3 maxed at 4k 100% on all 4 cores results in about 70 degrees, not overclocked.
 
I decided to rebuild The Red Baron, back to gaming in silence. :)

Matt, as you're back in dual 295x2 mode again I've got a few questions regarding my future upgrade plans.

I've currently just got the one 295x2 but now with my BenQ XL2730Z I'm already finding that running at 1440p in modern games at high settings I'm not going to reach the full 144Hz and benchmarks from the likes of GTA5 and Witcher 3 show I'm going to need more gpu power to keep the frame rates up. I really like the 295x2 as a card and given the money I've already spent I'd like to stick with it rather than upgrade to a new 390X so I think my best options are either another 290x for tri-fire or go the whole hog and get a second 295x2. For either route I'll wait for the 390 release and aim to pick up a cheaper second hand card.

In general for games with xfire profiles (sore topic at the moment I know) how is the scaling above 2 cards, is the jump from 3 to 4 still worth it?
For tri-fire I know a 1000w Superflower gold psu will be ok, for quad will a 1300w gold be ok assuming undervolting and no overclocking of the gpus with the rest of the system in my sig?
I'm still thinking of swapping out the fan on my 295x2 for 1 or 2 SP120s, with your setup running both as intakes how do you find it affects the rest of the system, cpu temps especially? It seem like a lot of very hot air is going to get pumped into the case?
If I went tri-fire I like the relative quiet of the 295x2 so I'd be loathe to go for a ref cooler 290x. Would a quiet 3rd party cooler (say a Tri-X) be ok with the 295x2 exhausting or would it likely raise the temps on the 295x2 a lot due to the hotter air inside. I'm guessing with a 3rd party cooler having the 295x2 set to intake would also be a bad idea for the same reason?

Thanks for any thoughts,

Ross
 
I stuck one of my bitfenix recon fan controllers temp probes to the bottom of the rad, seems to be the hottest area of it. Surprisingly it gets to 54c at the highest (so far)

And after some messing with fan configs, the one that comes with the card seems to be the best, running push pull with sp 120's seems to get into throttling territory. Even had push push pull with the front intake pushing onto a 120 and then the other 120 pulling air through, never made much of a difference. All ssd's now no mechanical hdd's :)

No clue what those odd looking marks are on the back panel, seems to be a flash artifact as they're not on it IRL.

Scaling with Xfire is usually pretty good to be honest. Two to three cards are definitely the sweet spot, though. At 4K scaling improves as you move away from the cpu bottleneck that you get at 1080P/1440P with 3/4 gpu's.

I used Quad with the 1300W SuperFlower Gold PSU so you should be fine with that. It will go up to around 1600W before it cuts out.

The Corsair Performance SP120's will run off the 295x2 fan header, which is handy. There are two different speeds, idle speed and 3d load speed.

I need more long term testing of my setup to see if it can handle all four gpu's at 99% load under extended gameplay. Because i use vsync (aside from online fps games) it's rare to see all gpu's maxed out at 99%. I'm playing GTA V at the moment maxed out but with all AA disabled and gpu's are sitting at 45-65% at 4K. Temps are around 65c max and the rig is completely silent.

I think a Tri-X would be a good shout as a match, but another 295x2 might be better. The 295x2's like to be undervolted, which can help keep noise and temps down much lower than air cooled cards.

What cpu have you got? You'll need a strong cpu for Tri/Quad.
