Morning all, having a bad time of it at the moment – a friend has bought a new PC and we seem to be getting a number of freezes, cpu load testing will cause the system to freeze within 10-15 minutes of full load.

Asus Sabertooth 990FX
AMDFX9590 4.7GHz 8-core
MSI GeForce GTX 970
Corsair 750W
Kingston 16GB (2 x 8GB) HyperX Fury Black

All this is cooled by a corsair H100i GT running flat out to ensure that heat is not an issue during the test.

Day 1.
System was crashing near instantly on boot, cooler profile set to full pump and fan speed to illuminate any potential heat issues.
Running Furmark causes system to hang – suspected gfx card or overheating.
The Ram and the GPU were swapped out with other hardware - problem remains.

Day 2.
Fitted an AMDFX8320 8-Core that we had going spare in the office, installed, worked like a charm – furmark and intelburn running for hours without issue. Suspected CPU issue

Day 3. Replacement CPU arrives, fitted and the same fault occurs as day 1. System hangs under load though GPU and CPU are within reasonable temperatures.
All default options are running on the motherboard, and set to normal mode within the Bios, no jiggery-pokery has taken place.

Reading on the forums some people suggest disabling C1 and C6 CPU options and physically declaring the memory to run at 1600Mhz rather than the 1866Mhz that it is defaulting to. No change.


Am at a loose end now, gpu, ram and cpu have been changed, and the motherboard is running fine with a different cpu.

Anyone have any suggestions?
 
If I remember, only certain boards were compatible with the 9590 because of it's very high tdp. I don't think the sabertooth is one of them.

If you already have an 8320 and a H100, you could just clock that instead.

Is the board a R2.0?

If not thats the reason.

The 9590 is a bit of a joke CPU, 220w :eek:

it is indeed an R2.0, not an r1, or a r2g3 - TDP is insane though, i agree :/

only the r2.0 is supported, which this is. checked on their site. 8320 is work equipment. cheeky enough that i used it to test the mobo in the 1st place ;)



Annoyingly, the same pc was built about 3 weeks ago (this chap wanted the same spec as the last build) and that one is working without a hitch.

Thanks for feedback so far guys. kind of at a loose end here at the moment!
 
What happens if you up the volts a touch from stock?

Id be tempted to say the board is struggling to give it the juice it needs despite supporting it.
 
VRMs overheating? My Sabertooth behaved the same until I got some fans blowing air directly on them, I was using an 8120 watercooled and anything over 4.5Ghz at the time would cause locks ups and the VRM Heatsink was scorching hot.

Had a couple of the ASUS min radial fans mounted to them and problem went away.

That's exactly how I was able to push my FX. The AIO cooler fan now blasts towards the cpu, which splats it over the VRMs with exit fans pulling that air out.
Having everything in a line front to back flow just didn't get enough air on the VRMs, so I had to improvise
 
What Case are you in? The heatsinks to the left of the cpu can get really hot. If yours are, try making the rear exhaust an intake blowing over the mobo.
