Need to unlock max gpu temp R9 295x2

[OracIe]

Forgive me for asking but are you sure the second fan you installed is blowing the right way?

 

[RavenLunatic]

Is the fan moving on the radiator and the gpu?

Err as it happens, nope the pull fan isn't pluged in.

Luckily it is the right way round. few.


Doh, it appears I was wrong and the pull fan was not working since it somehow became disconnected from the MB probably when I replaced the PSU. So rage over, although the Max temp for GPU2 is now 72C in Heaven which does not leave much room for overclocking.

Thank you to everyone for helping me get to the bottom of the problem and I will look out for that new BIOS.

72c is still quiet high, maybe you have bad airflow in the case, or ambiant air temp high in your room, but you can always add a 2nd fan to the radiator, 1 front and 1 on the back, maybe buy couple corsair or bequiet fans

I'm having a lot of issues with this card, random blue screens and crashes ranging from kernel security errors to Irql errors (win 8.1)

I tried the 14.4 drivers and wolfenstien and watch dogs crash reinstalled the 14.6 and the PC crashes during install of the drivers

I did a clean install on the machine this morning so I dunno what the issue is no OC on the card and I took off the OC on the CPU

Any ideas

Sounds like a stability issue with your pc mate rather than an issue with the card. Increase cpu and dram vcore if you want to keep you overclock going.

 

[Marine-RX179]

Your score looks pretty close to what it should be.

Here is two 290Xs @1018/1250

CPU @4.4 no hyperthreading.

Spoiler

Agree. It looks more like the i5 can't push the minimum frame rate to any higher than 94fps, thus bottlenecks the card.

Thanks the PC is at stock clocks on everything
Reinstalling windows again I think it's a dodgy driver issue

Kernel and IRQL sounds like unstable ram or a cpu, but we'll see.

What's the best way to check the ram?

What's the best way to check the ram?

I use 20 runs ofg intel burn test 'very high' to check stability, but no doubt there are better and less demanding ways to check it. If you do use it make sure you keep an eye on temps. I'm told by scotty that haswell gets quite hot when using IBT.

The Physics test in 3dmark11 on a loop for a couple of minutes will give the RAM a good stressing.

 

[andrewohare]

Ok I've swapped out the memory completely and see if that makes a difference

 

[andrewohare]

i have a 295x2, can i run another 290x and make tri-fire and is my EVGA 1000w PSU beefy enough ?

 

[JamesM]

No 1000W would be too low imo, especially when overclocking.

1200 minimum for me.

KERNAL error would point towards a CPU clocking issue not GPU

 

[andrewohare]

Thanks is it a massive boost and do i need an Xfire bridge?

on the kernel Error i had no OC on Cpu Or GPU, after reinstalling windows for the 4th time it all seems to be ok so far although bench on firestrike was low at 15.5k!

 

[Kaapstad]

No bridge is needed.

Make sure you can keep the cards cool enough with good air flow.

If you want to know what Hawaii trifire runs like let me know which benches you are interested in (out of the ones we use at OCUK) and I will run 2 and 3 way comparisons for you at the same clocks as a 295X2.

I tend to run Heaven and Firestrike .. ordered an MSI 290x Gaming today and a 1300w Superflower PSU

What speed do you run your CPU at ?

 

[andrewohare]

because of the errors i had currently its at 3.5 stock, but for the past year i have had it at 4.5 stable on water, have had it at 4.7 and will run ok but some games blue screen with the WHEA Uncorrectable error

4.5 seems to be the sweet Spot

I will do some runs on 2 and 3 GPUs using Heaven 4 and Firestrike @1018/1250 using 4 cores on my 4930k @4.5 (similar performance to a 4770k).
