8700k, 5.0 All-Core at 1.285V, OK?

[SlayerOfHellWyrm]

So, this is pretty simple. I'm new to OC.

 

My build is in my signature, but I played with some OC today, and managed to get an all-core 5.0 GHz OC on my 8700K at 1.285V (I know 1.35V is the upper limit) and under any stress test, it tends to sit around 60-70C with spikes to around 80 but never sitting there.

Am I lucky at all, or if you have an 8700K what do you have? I feel like my voltage may be a tad high, but thermals seem to be fine, and if I drop the voltage it's either unstable, or doesn't even boot anymore.

For ref. if you don't want to look in the sig, 8700K, cooled by a Corsair 115i Platinum (280mm AIO) in a Corsair 500D SE.

sounds like a good OC to me. 1.285v is completely safe to run daily and pretty respectable. depending on the stress tests you ran, you should rarely (if ever) see those temps in daily use

Intel XTU for 5 hours, Cinebench R20 multi for 2 hours, Prime95 for 2 hours.
 

Went from 2880 to 3491 in R20 mult, and 512 single. I don't recall the pre-OC single, as I forgot to snap a pick of it, sadly.

Is that what you see in e.g. hwinfo64 when running prime95? Just curious, since I am seeing 1.345V on my 8700K when running prime95 -- seems to be quite a big discrepancy in what I set it to in BIOS and what it actually is when under load.

 

EDIT: Forgot to mention that I am running all-core boost, tho.

yeah, you're golden. nice OC, enjoy it!

I did not use hwinfo64 during it, I had XTU open and I think it peaked at at 1.31V, so not really that much higher. Though, I'm not sure how accurate it is, by comparison to HWINFO64.

5ghz @ 1.28v is golden sample imo

See, I mostly asked because there's no way my first personal build is this lucky. I've also got +192 on the core of my 2070 and it's completely stable. Mind you, I've yet to touch the memory, I'm not that confident on how to deal with that, and if it will make a difference.

1.31V is quite a bit lower than what I am getting away with. I'm hitting 100C with my 8700K, so I am definitely somewhat envious of you

5.0ghz @ 1.285V is impressive (without delid ?). You won the jackpot on the silicone lottery. You might consider trying a bit more OC 5.1-5.2ghz as you have a big head room on your voltage.

Anything below 1.4V is fine. I got a loosing ticket on the silicone lottery with my 8600k. I had to do a delid to get it stable at 5.0ghz on 1,37V (been running fine for almost a year now).

If you try to get 5.1 or 5.2 and are having temp/stability issues then I would definitely recommend a delid with some liquid metal. 

I know some ppl are a bit afraid doing a delid but it is really simple actually.

While both are fun to play with, there's a rather big difference in applications

I don't see the problem here. Win - Win situation regardless

Yeah, thats a good one. I lucked out too and run at 1.285v with no crashes during gaming, which is around 5 - 6 hours a day straight. Haven't  stressed tested it with prime 95 or similar but feel no need to since i can run all my games at max graphics settings at very high fps and rarely ever crash.  Encodes videos with adobe media encoder and never goes above 75C. AME is usually a stress test itself when encoding huge video files. I actually came across a site called siliconlottery.com that sells rated chips that have been stress tested and gauranteed to run at a specific frequency. Was curious and got a 9700K rated for 5.1GHz... man it runs cool at 5GHz at 1.285v also. Havent tried 5.1 yet but really see no need for now. its extremely fast.

Seems great if it’s really stable. Had a core falling or unstable when running too low. Didn’t crash anything I was running but could still be noticed in gameplay. Had to bump the voltage up. Think I sit at 1.35 for 5.0 now but sat around 1.28 for awhile before I figured that out. Can only see the fall during bench tests. 

[AkSo2504]

I only got 4.9Ghz at 1.33 stable :(. Think I´ve got a pretty bad sample but temps are fine with delid
