just finished build

delided i7 8700k

 

My results:

5.3Ghz @ 1.4V, AVX offset 4, Cache 4.5Ghz - Rock Solid
i7 8700K, delidded, cooled by Noctua U12S

Gigabyte Z370 Gaming 7
16GB 3200Mhz CL Memory

congrats does your multiplier or volts stepdown

 

Nope, locked at that.

I do run it on 5.2Ghz though as there is a massive voltage difference. Only need 1.32v at that speed.

Even boots @ 5.4Ghz but most benches fail.

What about 5.2Ghz with no AVX offset?

The direct answer is - no, not at that voltage. To be honest have'nt played around with AVX that much as I just dont dont care about it.

Might be possible @ higher volts....

 

first try 5.0Ghz 2.6v

Its not a 8700K but maybe also ok for this thread

my daily setting on my 8600K



maximum prime95 non-AVX



and some benchmarks



all done with watercooling, cpu is delidded and original tim replaced by liquidmetal.

 

Great results on both chips!

 

My 9 series is running over 9000MHz

But that 8 series looks like people get worse results.

Awesome result. Almost 200W and only 66C, some great cooling too.

 

This is off topic but any 8700k owners here have 2 gtx 1080 TIs in sli? I really need to see 8700k sli supported gaming benchmarks at 4k resolution or above before I get one. Stock frequency benchmarks are fine as long as it's for actual games and not Timespy 3d Mark Firestrike etc. Thanks so much and sorry for the trouble

did you try benching or stress testing????? your pictures show you running prime 95 for less than 1 minute. did you also refresh the low/high ?? i'm confused

 

I'll contribute.

NOT STABLE bench conditions using intel extreme tuning utlility: (crashes at 4.8/4.9/5.0 at any voltage below 1.4)

my gaming profile (HASNT CRASHED YET):

delidded 8700k, 4.9ghz, 1.3 vcore, 80c highest temp. kraken x62 cooler on full fan/pump.

MCE OFF. sync all cores, xmp on ddr4 @ 3200 cl16, system voltages and agent are at 1.15. uncore is at 4.7ghz.

i'm using an asus 370 board.

 

delidded 8700k, 5.0ghz manual , 1..28 vcore, 65c highest temp. 2x 240 rad gpu in loop

MCE OFF. sync all cores, xmp on ddr4 @ 3200 cl14, system voltages and agent are at auto. uncore is at 4400ghz. not touched yet

i'm using an asus hero 370 board.

just tryed Adaptive Mode but not stable @ 1.31v temp 72 c Load-line Calibration 4
is it best to use manual or Adaptiv

 

Hello i got my 8700k recently and here are my results so far

Corsair 115i. Maximus x hero mobo.

8700k at 4.9ghz 1.28 voltage (manual). Load line calibration at level 6.
Cache untested.

2x8gb ram at 3733hz 16 17 17 39 2N
1.35v 1.225 vccio 1.2375 vccsa

I haven't run aida64 long enough to know if it is stable. But while playing bf1 for about 2 hours i haven't crashed yet.

Temps in aida64 is like 85 degress max.

Careful on auto settings for vccsa and vccio. Mine were were originally 1.37v on auto. Even setting it at a fixed 1.2375 vccsa my AI suite (asus) shows it actually running at 1.272v...

 

ok sorted overclock try for yourself
asus rog hero

my settings are for 5ghz oc voltage and speed step

x50 multi Sync all cores
Adaptive Mode voltage 1.315 Offset 0.05
Set IA AC Load Line to 0.01
Set IA DC Load Line to 0.01
LLC level 5
cpu c states enabled
xmp on ddr4 @ 3200 cl14
windows power plan balanced
prime 95 2 hour
bf1 3 hour
all good



just set cpu vccio to 1.2375
cpu syatem agent to1.15
so far so good




let me know if it works for anybody else

Does it contain the new microcode update that while solving a serious vulnerability, gimps the CPU's performance!?

Found a link but no changelog details.

Your VCCIO and VCCSA voltages are too high for a DDR4-3200 Kit.
Asus's XMP flags are overvolting your IO and SA too aggressively that default at 0.95 and ~1.05V respectively.

For a SR B die 3200 kit it should take you a 0% to under a 10% overvolt in these parameters that'll pass both memtest and gsat.
Intel's datasheet specifies a +-5% tolerance.

Dont expect to ever get it stable using AIDA64, try Realbench

 

Newbie to O/C - Getting a new 8700-K desktop for video editing. Planned config
Asus Prime Z370-A
32 GB DDR4 3200
Samsung 960 M.2 250GB (OS and Programs)
Corsair H115i water cooling

Would like to see all cores near 5Ghz
What are your impressions of Asus Prime m/boards?
All comments welcome
Thanks

 

what do u think i should set at 1.15
