Hi everyone. I'm having trouble getting this CPU stable. At first I thought it was an overclocking issue, because when I overclocked to 5.0Ghz, the system locked up shortly afterwards, and I wasn't able to boot into Windows again without getting a frozen screen immediately upon logging in. I was able to revert the clock back to 4.7Ghz in safe mode, but was still having the frozen screen problem outside of safe mode. Since then I have been tinkering with different things in BIOS to try to get this system stable. My current setup is this:

CPU Frequency Multiplier: x22.0 4400Mhz

CPU Voltage: 1.4375V

NB Frequency Multiplier: x11.0 2200Mhz

CPU NB Voltage: 1.1375V

HT Bus Speed: 2600Hmz

 

With my setup like this, I am stable at idle, and with basic web-browsing, checking e-mail, etc. Trying to do anything more complex like installing a program, or stress-testing with OCCT results in a lockup 5-20 seconds after starting the process.

 

System specs:

ASROCK Fatal1ty 990FX Professional, 2.0 BIOS

FX-9590 processor underclocked to 4.4Ghz

Corsair H80 liquid cooling, 44C at idle, typing up this post it has gone up to 52C max

16GB ram

Corsair AX1200 power supply

 

Thank you for your help.

Return everything back to stock speed (reset sys bios) and see if the problem goes away - if not, congrats, you kicked your mobo.

Alright, it's back to stock, which is interesting, because I thought I tried that earlier and it didn't work. Oh well, can't be upset that it's working. Ran OCCT again, and it lasted 2 minutes 30 seconds before locking up, temps had gone up to 62C by that time. What should I try next? I'm perfectly happy keeping the processor at factory specs now that I'm aware of the hassle that comes with tweaking this processor, so now I just want full stability under load. Thanks for your help.

"Corsair H80 liquid cooling, 44C at idle, typing up this post it has gone up to 52C max"

"it lasted 2 minutes 30 seconds before locking up, temps had gone up to 62C by that time."

 

Are those core/package or socket temps?  If core you are reaching the recommended maximum temp.  Ether way they are much higher than I would exspect with the 80i

 

Are you using the LINK software?  What is the 80i temp reported?

I would remount the 80i block/pump with new TIM to start with.  How's the air flow in the case, you need good flow on the mosfet/vrm's.  Many add a small fan to the backside at the MB cutout.

 

The 80i should give you 30-35C idle temps at stock clocks with the FX83xx-95xx cpu.

 

Core temp is displayed by a algorithm that is not accurate untill it reaches 35-40C, below that temp it display is much lower than acual temp and it changes rapidly. 

The socket temp generaly runs about 10C higher than core temp.

 

Recommended max core is 62C and socket is 72C, these allow for a large safetynet.  TJmax is 90C.

These are the temps reported by OCCT for the CPU. I'm pretty new to this particular software so I'm not sure which it's actually reporting. I don't have the H80i unfortunately, just the H80, so no LINK support. I'll reseat the block and see how that works. I was also expecting lower temps since my old 6100 processor was running right around your estimate of 30-35C idle.

 

Fans are setup with two 120mm fans on each side of the radiator to blow air out of the case, and one 120mm mounted on top pulling air in.

your fan configuration is wrong.  The CLC should be getting cool air from outside the case so those two fans will be intake, while your top should be exhausting the heat.  What is your case?  Maybe there are more fan mounts that you can make use of.

Those temps are still way high even if his fans for the H80i aren't configured right.  

I'm with madcratebuilder on this one.  Betcha that block is not seated right or the thermal paste isn't applied right or both.

Reseat that block, make sure you have the right amount and properly applied thermal paste.  There's an infinite amount of videos on the net for this.  I have often seen issues described like yours due to incorrectly installed heatsinks/TIM

I have an H80i and it works awesome.  With one hand I push down on the block so that it doesn't move and with the other I switch back and forth tightening the mounting screws so that it's even.  It should be tight and then one more half turn as the block shouldn't move at all after it's in place

You guys were right on the money. Poor thermal paste (too much), and bad fan setup. It was also getting a little dusty so I took care of that while I had everything taken apart. Idles at 36C now, and for a 220W processor I'd say that's pretty good. Here's the temperature results of a 10 minute OCCT stress test (it finished! Last time it crashed after 2 1/2 minutes!) Temps got up to 55.5C, again, much much better than last time. I'm going to run a one hour test later today, but unless something bad happens during that, I'd say this case is closed. Thank you for all your help.
