Question BSOD: CLOCK_WATCHDOG_TIMEOUT problem

Hello guys. Since yesterday I'm facing an annoying problem. When i'm playing any game that requires a bit more power i got this BSOD after 20-40 minutes of playing. First the game starts to slowing down, i hear weird noises. My mouse hardly response to any movement. And then this bsod occures.
I've tried to run OCCT test, but small packages after 5 seconds got me 50000+ errors, big packages 1 second and the pc is gone.
Now i'm running Prime 95 (26.6) test since 20 minutes and everything seems to be fine.
So far - temps are around 70 degrees and after 20 minutes 0 errors, 0 warnings. (blend test).

In BIOS my cpu has 39 and mobo has 34 degrees.
And it's working the same way with OC turned off.
Temps after playing BFV ~52 degrees and this is quick shot of what's going on, when the sound is dying, my mouse hardly moves, my character runs on it's own and that's it.

My config:
MSI Z170a Tomahawk
Intel i5-6600k (4,5GHz OC)
Cooler: Fera 3
Corsair VS550w
Gigbyte GTX1060 6GB

After 20 minutes, 79 degrees no spikes etc.


Any ideas what's may cause the problems?

Shouldn't then prime95 crash my pc when OCed?
Not necessarily. Prime95 runs a constant, steady load throughout. Loads like these are easy for power supplies to handle. P95 has it's uses, but synthetic loads like these are not an accurate representation of real world or gaming loads.
Gaming loads, are riddled with highs and lows which are actually hard on psus. These hills are one of the reasons people are constantly told to get a good quality unit.
Some cheap junk psu will not hold out for long on that kind of load - they're better suited for an office PC which generally runs a steady load.
For a gaming oriented PC, a $30 500w psu will burn out faster(maybe even literally) than another 500w one that cost $80. The $80 model is just going to have better quality parts overall, and is not going to exhaust as fast than a cheaper unit.

I have Corsair CS550M, I'll borrow brand new one today and give it a try.

Corsair RMx 750W will be a good option then? (i'm planning to upgrade my pc soon)

Ok, so i borrwed the brand new Corsair VS450W just to test the pc out.

Problem in games seems to be gone. They working perfectly fine but there is stillsomething i can't understand, i'll point it out.

  1. OCCT with small packages - no problem. OCCT with big packages - after 20 seconds, ~100 errors per second,
  2. in Battlefield V on maxed out (everything ultra) i have 71 degrees on gpu, 76% usage, 53 degrees on CPU, 72% usage
  3. When i push Battlefield V to the limits with rendering 200% etc. i still can't reach 100% GPU usage (maybe because the PSU is 100 watts lower?) - 74 degrees on gpu, 86% usage, 53% degrees on CPU, 59% usage
  4. CPU is Overclocked back to 4.5GHz iddle about 27-32 degrees.
What is limiting the GPU? PSU? Lower wattage?

What should I upgrade first then, i5-6600k to i7-9600k or GTX 1060 to RTX 2070?
Will new PSU resolve all the issues? Is Corsair RMx 750W CP-9020179 a good option?

1)I'm not familiar with the workings of OCCT, but if I had to guess, then your cpu overclock isn't stable. Or it could be your ram, you never did mention the specs for that.

2)Sounds ok.

3)There are a number of possible causes for this. I need to know the specs of your ram, and you need to check the usage of EACH CORE in game. Because if one or 2 threads - the Primary Threads - are constantly pegged at 100%, then that's a single core cpu limitation.
The fix for that is a faster cpu. If this isn't happening, all you can do is blame the developers. They're the ones who have to code these games to make use of all the resources available to them.
When they don't, you end up with games like PUBG, Rust, or ARMA 3, where high end rigs don't perform a whole lot better than mid range setups.

4)Don't see any problems here.


5)6600K @ 4.5ghz(~120w) + GTX 1060(120w) + 50w headroom for everything else = 290w
Corsair VS 450 +12v rail = 432w. Shouldn't be too much for a brand new one anyways...
I'm not seeing a psu limitation here.

6)Cpu + motherboard upgrade, assuming your ram isn't giving you trouble. 4 cores really isn't ideal anymore, unless all you play are older games.

7)No, a new psu may not resolve all issues. I do not have enough information on your PC to make that conclusion... but it was the cause of your recent BSODs.
That is a good unit, but 750w is more than you need, and would be a waste in a system that likely won't use half that on a regular basis. Today's graphics cards are less power hungry than they used to be.
A 550w of the same model will cover most users.

My ram is g.skill ripjaws v 16gb

750 watt because i'm planning to upgrade to i7 and rtx 2070 or 2080 that's why i'm planning more power.

About OC, its this way since 2016. OCed and its been working fine until this bsod 2 days ago.

1)1 or 2 sticks of ram?

2)Still don't need 750w for that. Even a 9700K @ 5.0ghz + 2080 Super is:
200w + 250w + 100w headroom for everything else = 550w(Get a 600w or 650w psu.)

9900k @ 5.0ghz + 2080Ti:
250w + 280w + 100w E.E. = 630w(Get a 650w or 700w psu)

9900k @ 5.0ghz + RX Vega 64:
250w + 300w + 100w E.E. = 650w(Get 700w psu)

Your planned build doesn't justify getting a 750w.

3)The crashing in OCCT large packages signifies some kind of instability.
Is OCCT a variable test, or a static one?

2x 8 gigs.

No clue about OCCT. I'm just trying to say that im using this OC for years without any problems untill this faulty day. Instable OC would cause problems during this 3 years. Other tests arę not showing any problems. Just this OCCT. Bit i'm worried why tho.

Ok, I don't understand a thing. I just plugged in my old PSU and played ~1h without any problems. OCCT - same result as with the new PSU plugged in.

Just checked each single core, when the game is running smooth, cores are:
80%, 72%, 88%, 86%

When i see freezes and stuter and weird noises, all cores are 100%

Ok, I just installed the new 750W corsair PSU. Problems seems to be completly gone. Just played Battlefield V for 1,5h without any single stutter. I've pushed battlefield V to the limits, all ultra, rendering future frames, 200% render scale. No single stutter for 20 minutes (couldn't play that way longer, because my pc runs this at 30 FPS). I'll test this all through the weekend.
