Pc reboot during load after overclock

Hi, I recently overclocked my i7-5820k to 4447.2 MHz, but when I try to increase the clock a little bit more the pc restart after I have saved the changes bringing it to the default settings. I've found a pretty good balance but I think I can push it more.

Any ideas why this happen?

I have a x99s xpower ac, 16gb ddr4 corsair dominator platinum ram and a 1000w 80plus gold psu.

Thanks!

You could be hitting a power limit or it's just not stable. Are you changing the clock in software or in the bios? And does it imminently shut off after clicking apply or when booting up?

The overclock is done in the bios.

For the last year I had a 650w power supply and it does the same thing at a little bit lower overclock so i don't think that the psu is the problem.

The pc first shut down after the changes to apply them, then a few seconds pass and it shut down, reboot and take me to the bios whit the default settings applied.

I've used this tutorial to do the overclock but rising a bit the values.

That's what happens when you put old geeks into new hardware, they overclock the reference clock (BCLK now, FSB in the past) instead of the multiplier even though the multiplier is unlocked and the motherboard allows multiplier overclocking.

 

I don't know how high Haswell-E's BCLK can reach but I do know your current core clock isn't the limit for Haswell-E yet. Try drop the BCLK back to 100MHz and increase the CPU ratio/multiplier instead.

 

Also watch your voltages, and not VID (VID is just the calculated voltage from an algorithm, not the actual voltage). Keep Vccin (CPU input voltage) below 2V, Vcore (CPU core voltage) below 1.35V, Vccsa (system agent voltage) and Vccio (I/O voltage) at 1.2V

Yes but high BCLK means high PCH and SA voltage, you won't be having much of your chipset and memory controller left if you do that for long.

Ok I've done some test: whit my settings I hit a Cinebench score of 1291, whit yours 1236.

I didn't know a lot of overclock, you think that your settings works better?

now you can try even higher CPU ratios to increase the frequency further. My settings are deliberately slower so you don't crash because of instability.

 

Also make sure you monitor the voltages with software like HWinfo in Windows when you do any testing.

I should change only the cpu ratio? 

What happen if the voltage go over 1.35?

if you are overclocking the CPU core, yes. BCLK affects the CPU core frequency, uncore (ring) frequency and memory frequency. On X99 all these can be tuned with ratios instead so there's no reason to touch BCLK.

 

Voltage past 1.4V could start ruining the CPU's lifespan rather quickly. I don't know your cooling so I said 1.35V, but that's only when you can keep temps below 80-85C

then 1.4V should be fine for you, but keep in mind that when it comes to voltage monitoring, software in your OS matters a lot more than the BIOS because voltages in BIOS almost always differ to what the board actually supplies.

so the CPU core voltage used now isn't enough. Just push more over there.

 

Also check for voltage changes between idle and load, I don't see loadline calibration settings in your screenshots so I don't know if you have problems there.

Ok im running a stress test right now whit 46 at core clock and 1.4V

Aaaand it bluescreen when i was writing this

Ok ill rise the core voltage more

The error is: CLOCK_WATCHDOG_TIMEOUT

ooi don't just endlessly go up the voltage, it has its limits. What is the actual voltage reported by HWinfo? Also you're at the point which your VCCIN isn't high enough, need 2V.

Whit 1.45V Aida say that the voltage is 1.456 with an 0.006V increase under full load

With this voltage the stress test seems go well whit 80-83C

so at least auto LLC is pretty spot on.

 

Still higher than what I would want it to run at. Seems like its 4.5GHz for you, the worst speeds for Haswell-E (4.5 to 4.8).

 

So the next thing to overclock is the uncore (ring). Raise the ring ratio one by one and stress it the same way

What di you mean with worse speed? It will be go better with 4.4?

worse speed = worse overclocks on Haswell-E. 4.4 will make it slower but is better for the CPU's health and temperatures.

Actually the cpu is at 4.6GHz
