Random Shut Downs (some tests already completed)

[Saguiro]

Hello everyone,

Here goes my problem,

When running AIDA Stress tests isolated i figured that my computer instantly shut down when i press start for the FPU Stress test, while all other components are okay, i tried those tests because my computer randomly shuts down and i could not figure out why(i run mem test for more then 8 hours without any error). My processor is an AMD 9370(bios 2501, which i updated because i had the same issue without the update) not overclocked, with 1866 dual kit 16GB Kingston Hyperx Fury (i configured the latency's as written in the official kingston website as the better configuration, did not overclocked it) in a sabertooth fx990 r2.0 in a NZXT phantom 820 with a corsair h100i closed water cooler (while doing the 100% stress tests my temperatures never exceed 80 C) with a corsair TX 850 (it have no problem with this since i used it with my AMD FX 6300 before buying the new one).

My GPU is a RADEON Sapphire 7950 (never overclocked too) and i use a 128GB Kingston HyperX 3K SSD, my peripherals are a Corsair mouse m95, corsair headset 1500 and razer keyboard blackwidow ultimate.

How should i proceed to try to solve my problem of random shut down?

Thank you for the attention,

Jean.

PS: i have never tried to overclock any of my hardware, they are at stock configurations.

Some help please?

How are your voltages?

Check the max voltages reached with fx HWmonitor or other software. Compare to the Voltage set in bios for your CPU.

Some times a stress test causes voltage spikes which can cause these crashes.

80C sounds pretty hot, even for that CPU. (220W TDP, right?).

 

Set your H100 to full speed and see how that works with your temps. Also check the temp limit set in the bios.

I Turned the voltage down and it apparently solved the problem, going to test right now.

Thank you

How do i check my temp limits in the bios? it is a H100i and it is full speed, so as all other coolers in the case

I've read the manual but after more than 10 hours of work on a Saturday my brain just gives out 'bla bla bla'.

 

But take a look here:

 

http://www.overclockersclub.com/reviews/asus_sabertooth990fx_r2_review/3.htm

 

That should explain where to find the settings.

 

 

An FX CPU shouldn't run above 72°C.

 

Also did you plug in the H100i pump into the CPU Fan connector on your mobo? You should do that and turn off any CPU Fan quiet mode. The pump should always run on max. The fan depends on the temperature you're getting. But if you want it cool it should also run on high, which you've probably set from what I've read.

Ok, i set a setting of the cpu to 2200 instead of auto and turned down something to 1.4 instead of 1.5 and it is working almost perfectly, with one exception, sometimes, usually when playing videos the monitor freezes for a sec, do a strange noise and come back to normal very quickly, is there a way to solve this? but just to make clear, if to solve this i will need to be unstable again i prefer to just let it the way it is.

 

Thank you all for the attention.

Take a look at your bios again and make sure that 'APM Master Mode' (Application Power Management) is set to ON and that HPC Mode (High Performance Computing) is set to OFF.

 

Short explanation:

APM: APM ensures that your CPU stays in it's thermal design specifications. Eg if the CPU runs above it's thermal max rates it throttles down.

 

HPC: Unlocks the thermal design specifications. Poor amount of more Hz for a freaking amount of power usage and heat. You don't need that.

If you're having problems after that, try to disable APM Master Mode too and watch if it's getting better. (That'll limit the Boost clock of your CPU too)

 

BTW: What OS are you running? Bc there've been fixes for Windows 7 for the FX CPUs. If you give me a head up I can look if I still have the links if needed.

It did not help me

Actually i figure out something, but still do not know how to solve,

Disabling the vertical sync fo the games makes it do not happen, but i really would like to play with it
