Use fixed voltage mode, set CPU Loadline Calibration (LLC) level 1 to reduce the vDroop (load vCore lower than BIOS set).
LLC is already at Level 1 since i started.

Load Vcore lower than bios i cant find this.

Mana cari?

Core voltage stood at 1.344 idle and load.

Ran aida64 stress test all the way the vcore is the same.

Hi all,

Does anyone here got his hand on 8086K? How does it overclock?

I think it's time to retire my 8700K and buy a 8086K if it is really good. I think I got a lemon 8700K.

My chip
Default VID (Default BIOS) - 1.056V
Motherboard - Asus ROG Maximus X Hero

OC @4.8GHz, 0 AVX offset
-Manual voltage - 1.27V
-LLC - LVL6
-Prime95 version 29.4 Small FFT test - No error (1 hour)
-Prime95 version 29.4 Custom 1344K >95% Memory - No error (3 hour)

OC @5.0GHz, 0 AVX offset
-Manual voltage - 1.34V (Lower voltage will BSoD Prime95 Small FFT test)
-LLC - LVL6
-Prime95 version 29.4 Small FFT test - Error in less than 3 minutes
-Prime95 version 29.4 Custom 1344K >95% Memory - No error (3 hour)

I have tried everything to get it stable @5GHz Prime95 Small FFT test but to no avail. Based on what I've read here, anything over 1.35V for 5GHz is a lemon. Should I try my luck on 8086K? I really want to know how good does it OC. Any help would be appreciated. Thank you.

Yes, the temp is around 90C when running Prime95 small FFT @5GHz and my chip is delidded with Thermal Grizzly Condactonaut. The temp is around 85C @4.8GHz. I am currently using Cryorig A80 which I think should be around the same performance as NZXT or Corsair AIO. Should I change to custom loop for my chip to be considered an average chip and not a lemon😭😭? I saw a lot of members here just getting to 5.0GHz with normal 240mm/280mm AIO. I still wonder how is delidded 8086k perform😂😂😂

A screenshot of 3 hours custom blend test @5GHz? I have already dialed down my OC to 4.8GHz. I can give you a screenshot of 1.35v @5GHz though since it fails so fast. I am going into BIOS now.

Oh, that would take some time lol. Would you think this CPU is a lemon though? 1.36v load and still fails small FFT. This is a screenshot of stock VID. What you meant by stock VID is the voltage shown on BIOS default settings right?

Can you suggest a good 360mm AIO? Plan on doing a front push pull setup. Will be doing a 3 hours custom blend test 1344K again tonight and will take a screenshot, with this test my temp is around 60C only though. I am currently using BIOS 1401, I don’t know if it is good enough, waiting for your test result😀👌🏻

Edit: My stock vid @BIOS default is 1.056v but when i disable MCE it goes up to 1.088-1.104v

I don't know because I delidded my CPU when I first got it . So, based on your calculation, 1.104v should be the realistic stock VID before delid. A lemon as expected lol. Would be nice if you can do a review of 8086K.

Adoi baru nak mimpi 8086k kalau macam ni cancel lah heehe

hi, wanna ask how about corsair "H100i V2" or "Fractal Design Celsius S24". reviews and comments some say corsair full load works very loud and pump fail very common, fractal very quiet but falls behind corsair in terms of cooling but quality very good.... so confusing.
been browsing these 2 coolers 240mm, as my case not enough to fit in top 280mm.
any recommendation for 240mm AIO?

Sifus, I'm planning to get a new board for my 8700K (Quite lemon chip i think).
May I know any good board that is good for OC and the only constraint is the CPU itself?

TQVM

Budget 1.5K

PS. normal size board

Hi owikh84

Cant hit stable 5 GHz on 1.37 but stable with 2 AVX at 1.31
Haha. Can say lemon but also can say not that lemon?

Rip my chip xD

Will get new mobo and try it out haha
But I think I will get the almost same result

Is AVX important these days?

Hi!
Came out of retirement (stop OC'ing since socket 1151) and got myself 8700K + MSI Gaming M5 

Woah so many new features since last gone into the bios years ago lol, pretty cool really, with LLC can now be tuned specifically for example.

Managed to stabilize 4.8ghz @1.220v (in bios). A little bump in voltage in CPU-Z because LLC @ Mode 3.
[attachmentid=9965970]

Anyway about this AVX thing, it's not really necessary for stress test is it? Specifically Prime95, where you can disable it in local.txt.
And what's the point to offset it where in real application 0 AVX machines won't do extreme load like with all the stress test? Perhaps for Benchmarking purpose?
My system requires 3D rendering and heavy Photoshop usage, prefer to keep the clock fully optimize.

Temp is okay, maxed 75~ish Celsius with prime95 Small FTT with AVX disable, over 2 hours. Can do better when I get some liquid metal TIMs like Thermal Grizzly. Using 240 AIO cooling.
With AVX enable straight gone into 95C 

Hi all sifu,
Idk if im doing the right thing or not . My first time using prime95  
just assemble 8700k with maximus hero.

First i OC to 4.8 with 1.2V, run cinebench and prime95. all looks good. Then i tried 5.0 @ 1.2V --> BSOD
and finally i try 5.0 GHz  @ 1.25V and run for few hours still no bsod. but the temp quite hight

Is this the right way to test the cpu?

Here my core voltage after clear cmos.

Hi.
Got stock i7 8700k with scythe ashura (perform like 212 from cm).

Wonder if: 70-75 gaming 80-82 cinebench is ok for room temp w/o aircond.
And one more thing is that with side panel off: everything drop by 4-5 degree cel. Is this cause by inadaquete airflow? Im running 2 front in 2 top out 1 back out. Might swap out front intake FNv2 120mm to corsair ML140 @@ will this help with the temp?
And if i plan to undevolt (until i can afford better cpu cooler): should i use fixed or offset? read on net that offset means it’ll undervolt as well at idle. Harder to get stability while fixed runs at that voltage all the time, am I correct?

managed to get offset to work, with trial and error using LLC haha.
which aircooler would u recommend?
need ram clearance for vengeance pro and preferably not too hard to install haha..
dark rock pro 3 looks really nice, but heard its hard to install and block 4 ram slots lol
