AMD Radeon R9 295X2 Owners Thread

Not looking good, first few game runs are a bit if a mess. Random stuttering, fps up & down like you wouldn't believe.
Temps are around 68c,so should be OK. Will do more tests later.
 
Disable ULPS and use unified gpu usage monitoring Rob. Although ULPS has never caused issues with me on Hawaii, it's more of a better safe than sorry think to try when you have stuttering on crossfire as that's not typically normal behaviour. Unified gpu usage monitoring displays more accurate (and less erratic) gpu usage reading in afterburners on screen display. Finally check the monitoring tab and make sure it's at 2000.

Thanks Matt, think I have most of those settings already, but I'll check everything later & report back.
First few mins everything seems OK, but but after that is when the problem start.

You have positioned the rad on the correct place yes?

It is on higher level than the card, with pipes down, and blowing COLD air to it.

Yep, rad is positioned above the GPU (Exhaust) & pipes down.



Temps are around 68c so don't think temps are a problem.

EDIT -
Unparked cores, & run a couple of loops of Heaven @ ultra 1440p & seemed to run ok. Average 75fps. Temps 69c GPU CPU 55-60c
Will try out a few games later to see how it is.

What fan you are using there? Because it doesn't look like the stock one, nor one with high static pressure
 
Corsair SP120 QE, I've used it on several rad installations with no problems.
As I said, temps are around 68c so shouldn't be a problem.

Since unparking the cores, thing seem much better, Couple of loops of Heaven & Firesrike both ran well & 3x loops of Grid Autosport benchmark gave me an average 128fps on 1440p ultra.

It is not good enough fan. Use the stock or get one with higher air flow and static pressure. 37 CFM is not enough.

Even 2 Enermax Magma are better, or one Apache
 
The advanced design of the SP120 provides the higher static pressure that radiators and heatsinks demand
Click to expand...

The wide body, low-pitch blades of the SP120 fans combined with the custom housing provides outstanding static pressure and airflow through heatsinks.

However I'd recommend the SP120 High Performance Edition, of which I use :)

But he says he doesn't have temp issues

Good to hear, seems to help a lot of people this one. No idea why as it's never made a difference for me personally but as always i guess YMMV.
 
I'd be putting 2x 1850RPM Gentle Typhoons on the rad of my 295x2, if i owned one. I'd use the Noctua Industrial 3,000 RPM fans (highest static pressure I've ever seen on fans ) but they don't play nice with fan controllers as they're four pin.

I used Piranhas, Apaches, and Enermax Magmas.

I had the best cooling - silence ratio with the Magmas, while working at 75% speed. At 1100 overclock it never gets more than 60C, while the system is silent.
 
I've got a couple of Noctura NF-P12 PWM fans, which I may try out.
The SP120 fans I've always been happy with, I ran them on my last 120 rad fitted to a 290 & gpu never went over 75c.

No? I've used a fair few 4pin fans on a fan controller and they generally work fine. About the only thing I've seen is maybe not reaching max rpm, though that may not be a problem with 3k fans :D

What issues did you see?
