AMD FX 8350 Overclocking help

I recently overclocked my amd fx 8350 to 4.82GH/z and got it stable according to prime95 but whenever I play Watch Dogs it shuts off no matter what settings I use in Watch Dogs. Watch Dogs is the only game this happens in. Any help would be greatly appreciated. Thanks in advance.

My specs are as follows
Cooler Master Haf x Nvidia Edition
Amd FX 8350
Asus Crosshair V Formula-Z
H100i in push/pull config on the top of my case.
8GB of G-Skill Ripjaws X DDR3 1600MH/z
EVGA GTX 760 4GB with acx cooler
Apevia 680 psu
LG Blu-ray Burner
3 7200 RPM sata hard drives
Windows 10 Technical Preview

Then your CPU isnt stable. Just because one program says it is stable does not mean every load case is perfectly stable. Just back off the overclock some or add more voltage till you are stable. If you go the voltage route then make sure you are staying within heat limits and are within the recommended 24/7 voltage area.

But isn't prime95 the most trusted stress testing program for stress testing cpu's

For how long did you stress test with Prime95? Because Prime95 doesn't "tell you" anything. Only time does. Let me guess. 1 hour? 2 hours? Now click on my signature for the solution to the problem.

For quicker results, albeit with a small margin of error, you 're better off with IBT AVX Very High (or Maximum). Prime takes time. For me 8h Blend is the minimum one should run before claiming "Prime-stable".

Prime is only stable if you finish all the calculations.... roughly 24 hours.

IBT AVX high is good like undervolter has already stated.

-What voltages are you running with?

-What are your temps with a H100?

So I should run prime while I sleep or at work right?

my Vcore voltage day to day is 1.444 but when stress testing it gets to 1.467 but I have my Vcore voltage set in the bios to 1.488 & my normal day to day temps with the h100i are 45-55 degrees celcius but on full load like when stress testing I hit 79 to 87 degrees celcius

Btw how do you tell if an IBT stress test failed?

I 'd say that it would be a reasonable conclusion.

Simple. At the end of the end, you get a popup that informs you openly on whether you passed or failed. Just remember to run Very High or above (or at least High), as "Standard" is not very stressful. It should take about 20 minutes. You can find the test in the 1st page of the VIshera Owners thread.

I'm running IBT at maximum stress level

I'll run prime when I go to bed.

correct me if i'm wrong but 79C to 87C is a bit over the safe temps for an FX processor. To my knowledge its only safe aup to 62C.

That is way too hot for the FX, and that alone can and/or will, cause instability. AMD recommends that core temperatures do not exceed 62.5C. Nice VCore on that OC though.

Well I'm too poor to buy good quality thermal compound. I'm just lucky I was able to get this mobo, cpu & liquid cooling kit. My original mobo was an msi mobo not meant for overclocking the fx 8350. I only got this mobo cause I sold a laptop & the cpu I used my xmas money to get & I did chores around my parents house to get my original liquid cooling kit which was a refurbished h100 which I had a problem with so I sent it to corsair & they sent me a h100i because they don't make the h100 anymore.

I just thought is was weird that Watch Dogs was the only game I couldn't play without my pc shutting down

IBT just finished & said my cpu is stable & said I passed.

I mean ever since I installed my asus mobo I can't play Watch Dogs. I could play it just fine on my old msi mobo.

Have you tried running memtest to make sure your RAM isn't acting up? What about GPU temperature, since it's shutting down while playing a game?. Since a game wont get the FX nearly as hot as IBT AVX. Do note that IBT is not a very good indicator for long term system stability, Prime95 blend is better for that.

Do you have volt sensors, or better, a physical volt meter to measure the PSU with?

Random shutdowns can be a number of things.

Edit: Since it's an ASUS board, if you have bad case airflow (due to the fact that you are using a CLC), and the VRMs get too hot. It will throttle and/or shut off to protect itself. GPU heat may make it kick in faster. Just speculation there.

not on my asus mobo I haven't run memtest but on my old msi mobo I ran it. How do you measure the volts on a psu with a volt meter they didn't teach me that in my computer repair classes. Come to think of it they didn't teach me very much of anything about using a volt meter

& they are not random shutdowns it only shuts down while trying to play Watch Dogs otherwise it works perfectly. It's almost like Watch Dogs triggers it for some odd reason.

The shutdown doesn't even show up in the event viewer for some strange reason either.

If it's a single rail PSU, just stick the red probe on the nearest +12V line, and black probe to common ground. Multi rail is a bit more annoying; as far as measuring for GPUs with their own rails. Measurement units in VDC, though the range depends on the volt meter. Mine is VDC with the range selector of 10 to 100V.

If you have a spare fan, try standing it on the back of your graphics card (if its a plastic fan), and pointing it at the NB/VRM heatsink. That helped a lot with my Crosshair VZ, the NB does get quite hot sometimes.

Really trying to remember tricks for the crosshair VZ, but I didn't have this problem. Using latest BIOS and NVIDIA driver?

how many torture test should I run with the prime95 blend?

my psu is a single rail psu as far as I know

Really dont recommend running it with the FX getting that hot. In that range, it's bad for the chip. Especially overclocked.
The standard 8 threads, 8K minimum size, 4096K maximum size should do, but the test takes time to fully complete. Again, do not recommend with temps getting above 70C.

Edit: With about 75% of max ram (or more).

now that I've plugged in my fans directly into the mobo my temps are only getting to 81 degrees celcius when doing a stress test

What other games do you play? What's odd is that Watchdogs is the only game - if you play other demanding games it's not as clear cut as saying "a overclock is bad". Might simply be a software issue if that's the only problem you have. What kind of crash is it? Application crash, windows crash etc. Do you need to restart your computer or just shut Watchdogs off?

Having said that, those tempetures are high, I'd drop the overclock by a few hundred 100MHz just to bring it under manageable tempetures. It's not likely you will be able to tell the difference between a 4.6GHz and 4.8GHz FX 8350 anyways.

If you reduced your overclock to something like 4.6GHz or 4.5GHz, does Watchdogs still crash, would other games still be fine?

I play the mass effect series and the borderlands series and star wars the old republic and those games I can play just fine @ ultra settings. & I mean Watch Dogs just shuts off my computer just like if you get a power outage that kind of shut off but the only difference is I have to completely cut power to my psu & unplug my power cable then wait for everything to completely loose power then plug the power cable back in and restore power to the psu then I can turn my computer back on. Btw I ran prime95 last night and my computer froze sometime during the night while running prime95.

Which temperature is reading 81C? What program are you using to monitor?

If you're not already, try using HWinfo64 and report back.

Depending on what temperature you're reading @81C, I'd take it easy on the stressing until you figure out what you need to improve.

The program I use to measure my cpu temps is asus ai suite's sensor app. & it list the actual cpu and mobo temps as well as all my voltages

right now my cpu is running at 46C and my mobo at 31C
 
#23 ·
It would be beneficial if you were to download the HWinfo64, it gives a much more indepth look at your rig.
 
#24 ·
I ran IBT again while watching the temps in HWinfo64 and the temp only got up to 85C for the cpu. IBT still said my oc was stable.

"Only" 85c is gonna roast your chip in the socket.
