Working on a 5820k OC

[Tír na nÓg]

Working on my 5820k 24/7 stable OC for the last couple of days.

Decided to lower the clock to 4.8GHz/4.3 cache.

I noticed that if temps stay below 80c, stability increaes,. So added a few fan for push/pull (running a H240X+280+140, with a 780 ti in the loop).

Ruuning p95 now, and after 45 minutes, that's what I got (will leave it running overnight):

Nice chip!

Thanks E_D!

And the build that go with it... Sorry, not so neat...

 

[Joe88]

J batch chip?

What in the hell am I doing wrong to be at 4.7 and 1.4v, I don't think I have ever seen a 5820K stable at 4.8/1.33v...

Will it pass realbench stress testing at those settings?

It passes [email protected]/1.32v. [email protected] (realbench after 20min and P95 after a bit more than 3 hours). Will try RealBench/[email protected] tonight. I am pretty sure p95 will pass (Passed [email protected], 6hours). Don't know about RealBench.

Nice chip My better 5820K could make 4.7GHz ~1.35V when I was testing it last time and it was one of the best on hwbot ( on ss/dice it was beating others on LN2 ).

I got 1992pt on XTU@4920MHz, but I hit a wall above 4940MHz. I believe it's heat related: 93c and XTU freezes.

I will certainly give a try tonight, when the fresh summer Irish breeze blows gently! I'd like to pass the 2K barrier

That is a sweet overclock for 5820k.

 

[Brando]

whats the best you can get around 1.2V? wanna trade?

 

[Tír na nÓg]

^I just tried yesterday: I run 4.6/1.215v (P95 and Realbench stable). Thought 1.15 was OK for 4.5GHz (Prime95 OK), but RB crashed after 30 mins. Need 1.17 for 4.5GHz.

No no no, I keeep it!

I just found older result on my 5820K



I wonder what bandwidth would be on new memory kits.

 

[Tír na nÓg]

^Oooooo... That's good!

Is it on dice?

 

[Woomack]

Yes, it was on dice. I was using early Ripjaws 4 kits. I guess that now results would be better on new Samsungs but I doubt I will test it again on dice or ln2 anytime soon.

Ran 4 hours of RB last [email protected]/1.26v and 4200/1.2v cache. Ambient 24c:

I'll keep it like this except for benching: don't want it to get degraded for a 100MHz when IPU intensive bench/[email protected]/1.43v):

Dam sweet clocks on that 5820! Going to send stereo555 a pm with this link to see if it'll help him out. He's got a 5820K and an ASRock X99 OC Formula Extended board and has been having issues since day one with it. Can't even get 4.1Ghz stable He's pretty flustered with the setup.

 

[Tír na nÓg]

Sure Nebulous. Will help if I can.

 

[stereo555]

Sure Nebulous. Will help if I can.

Gonna hit ya up in the very near future about some settings I maybe missing on my 5930k and Asrock OC Formula 3.1 .... coming from an old x58 system I feel like a super noob again . Thx too to Neb for pointing this thread out .


Congratz on a super overclock !!!

Thanks Stereo555.

PM me anytime!
