AMD Radeon R9 295X2 Owners Thread

my OCUK mini dp cable causes lines on the screen :( Going back to the adapter in the box with a normal dp cable which works fine. Shame it sticks so far out the back of the case though can't fit my case where it normally lives now!

Should be on by default iirc, if you have 2 in crossfire the idle card light will go out.

Only got the 1. Seems odd.

Also I've found that the card starts to drop frames big time when it heats up to about 68c in Unigine Valley. As in it goes from a happy 90 or so down to 30 - 40, stutters for a bit then goes back up. Anyone else experienced this? Happens in Battlefield 4 as well after the card has heated up.

There is also an empty 2 pin header behind the fan on the pcb, is this the same for everyone?

I'm not 100% sure but isnt the 2 pin header for the pump ? :eek:
 
The card shouldn't throttle until 75C

But my scores with the same sort of system as others are 200ish down. I turned ULPS off and changed power profile to 'High Performance' from 'balanced'.

Ran Unigine again and it was down from 2400 to 2250...Weird.

lol I hope not. Can someone check on their card for me if anything is plugged into it?

Was my card made on a Friday afternoon? :)

Possibly a monday morning :p

This is taken from a bit-tech review.

Elsewhere on the PCB we find the PLX chip as well as a standard 5+1 phase power arrangement for each GPU. All of the memory chips are on the front of the PCB, and as there are now eight rather than sixteen per GPU, this means AMD has switched from 2GB to 4GB chips, presumably to save on die space and thermal output. We also see the two 4-pin fan headers as well as a 2-pin one that powers the pumps.

Ugh oh explains a lot then I guess. Just took this picture.

You must be kidding me.

That is why the second GPU is so lazy?

I will check it when the download of the 14.4 finishes.

The GPU2 goes to sleep the moment it hits 68C throttling down to 600 mhz, while during valley even GPU1 never bothered to wake up and is working at 70-80% while at 70C-74C

Possible to plug it in or is the cable not easy to get to?

Cable is jammed under the heatsink.

I don't think I want this card anymore, who knows what damage has already been done to it, probably halved its life. Hopefully the new batch of cards will turn up shortly.

Yeah better off, that was a bit of a screwup from whoever assembled it. :eek:
 
Got my waterblock onto my card now. No pics atm, But the support for crossfire is terrible anyway lul.

Benchmarks showing worse FPS than my one 780TI card am pretty sure somethings up with it no doubt. :mad:
 
My connector is on it seems. At least the one that shows under the red fan.

I replaced the rad fan with 2 Piranhas that are working at 100% speed atm. (they are tad loud).

used the CCC overdrive, overclocked the graphic card to just 1110/1625.

Going to give it another run on Valley.....

EDIT

OK.

Card seems right at first glance. The overclock didn't throttle down, temps hold at 70C & 64C respectively with the two Piranhas and had no throttling.

See if all OK tomorrow and going to raise the CPU back to 5Ghz (lowered it just in case), and see how far I can push it before I got under "proper" water.

However I am sure there is something wrong with the pump. Where can we find out if the pump is working at 100% or is throttling depending the heat? (also where do we set the fan speed for the red fan it working at 22%)

The card on Valley doing 4470 at extreme 1110/1625! That is less than some 7970s, and some of the time the card was working at 80-85% only, for whole frame test. (no speed throttling and temps bellow 70C and 64C) Darket with similar overclock has 500 points more.

(Kaapstad or LtMatt around, might provide some help?)

EDIT 2. Did another run with 1130/1625 and had the GPUZ open. hmm 146C???????
