AMD FX-8350 Overheating; Blue Screens

Hex- · Feb 18, 2016

This is what I know, the blue screen errors are CLOCK_WATCHDOG_TIMEOUT and WHEA_UNCORRECTABLE_ERROR. Both are being caused by my CPU doing one of two things (according to hopefully reputable people). From what I understand, the CWT error is caused by thermal issues and WUE is caused by voltage sagging. I originally thought these issues were PSU related, so I replaced that and the issue persisted. Then I changed my board in hopes of fixing the sagging but that didn't work either. I have an H100i GTX cooler and my temps are actually pretty high based on what I've been told they should be. My CPU idles at around 40 degrees Celsius and reaches around 70 degrees under load. Usually I don't even get the chance to hit 70 degrees because the CPU will start sagging and will crash because of that. I've reapplied thermal paste and made sure that there were no air pockets so there's no way it's the cooler.

Something needs to be replaced, the last original parts I have are my CPU, my GPU, and my RAM. I've run memtest with no issues and I'm not overclocking. What needs to go?

Attached an image of a graph from OCCT to show the sagging. I have no temp pics.

What power supply did you get? Replacing a power supply with a bad quality one won't help fix things.

If those temperatures are accurate, that is bad, maybe there is an issue with the cooler or you don't have it pushed down properly. Maybe the CPU is also faulty.

As an aside, there is some neat info to read here http://www.tomshardware.com/answers/id-1722394/amd-8350-maximum-safe-temp.html especially towards the bottom where there is a system shown that was actually designed to generate heat rather than try to lower it.

I got a Corsair CX850M.

I did another little test. I underclocked my CPU to 3.4 GHz and ran Warframe (a game that always crashes my computer). My hope was that the CPU would be able to handle sagging since it wouldn't need as much voltage as 4.0 GHz. I had OCCT running in the back and when my screen started flickering I took a screenshot of the graphs. I'm not sure if that helps at all with diagnosing the issue. (The temp is going down because I took the screenshot after I closed the game.)

That power supply is iffy, but likely not the cause of the issues. Although there are several reviews about CX power supplies having less sturdy components that other models, almost every single build seems to use them. Or at least people that have issues with their computers and post here

Did that underclock keep things stable? The temps there at under 43 are OK, but is that idle or load?

I have the same problem with this processor the factory heat sink sucks. I would recommend a high quality power supply. I think you are already running a liquid cooler maybe try getting a bigger cooler if not dont stress to much i have the same one and i get the same temps

I just feel like it's probably not the PSU because replacing it once before didn't fix the issue. Sadly underclocking didn't keep things stable. The image of the OCCT graphs is from the underclock to 3.4 GHz

That's what that stop error means. The CPU is overheating / overclocked

Saying that your psu is new, even if its of iffy quality it probably isn't your problem (at least for now). I would focus on the H100i GTX. The H100i GTX is a good water cooler, but it is only as good as its installation and it could be having a pump issue. Water coolers can be tricky to get in the proper position to get the best cooling, if your fans aren't able to cool the water block then the cooler itself isn't going to work. I typically always try to mount the water block on the top of the (tower) case (hopefully your case has dual vents on the top) and have the fans pushing the air from the bottom of the water block right out the top of the case. If your setup is good and should be effectively cooling the water block then you should check to ensure your pump is running. If your pump is failing and not running properly then your temps are going to skyrocket. A properly working H100i GTX should never be overheating a FX 8350 at stock. I've seen guys pushing 5.2Ghz and 1.6V with a H100i GTX with temps lower than yours.

The H100i GTX also has software to set custom fan curves and control your cooling, make sure you have that software installed and that your fan curve is set up properly. If you continue to have these problems, saying you have replaced the motherboard and psu, I would get in contact with Corsair as I think you have a failing pump in your H100i GTX. That is exactly why I switched from the H100i GTX to the the NH-D15. With water cooling you always have the risk of a pump failing or a coolant leak which could be a gradual thing and cause higher than normal temperatures or quit all together and cause the CPU to shut down or even worse fry. With the NH-D15 there really isn't anything that can fail and it has the same cooling qualities as the H100i GTX. I would say your next best move is to contact Corsair and tell them you suspect that you have a pump issue with your H100i GTX.
