i75820k Crashing On Overclock

[Ahad Beg]

So i Have a I7 5820K 3.3 GHz i am able to get it to 4.5 GHz

I set voltage to 1.3 and DDR4 ram to 2400 mhz

pc boots up and is fine but when i run stress test from intel it freezes up.. and i have to force reboot.. i even set voltage to 1.300 and it lasted about a minute longer then before crashing..

what can i do or what do i do? Anyone can help via discord? why isn't it working? I have my cpu at at 4.2 ghz atm with 1.250 voltage

Instead of jumping up to 1.3, work your cpu and ram one by one up until it crashes and pull it down a notch after it does.
Sadly, oc-ing varies from one processor to the other due to the "silicon lottery". There may be a I7 5820k that oc to 1000 mhz higher while another i7 5820k can just have 200-300 mhz oc.

well i was able to get it stable at 1.290 cpu volt.. at 4.3 ghz... but then i got thermal throttling intel system test said... so i put it back to 4.2 ghz and 1.240 v or 1.230 v... and its fine and running good enough.. i have a 120 MM liquid cooler.. is that too smalll? do i need 240 mm?

What motherboard do you have?

i7-5820k should be a good overclocker. I got mine to 4.6Gz @1.25V stable, but for 24/7 rendering I run it at 4.2Gz 1.15V.

The peripheral voltages such as vccsa/vtt and vccio have a tendency to overvolt if left on auto so you need to dial them down.

I think most crashes during stress test is due to vdroop.

Yea definitely 120mm aio won’t be enough. Get a thick 240mm or big air cooler like silver arrow ibe or d15. i7-5820k is a hot chip.

Delidding should help too

well, since you have reached the stable oc, try upgrading your fans and maybe try re-appling your thermal paste. For fans I recommend Noctua since they are pretty good as per my experience.
