Both ROG Strix Z370-F (RM875) and AORUS Z370 Gaming 5 (RM932) have almost identical VRM configurations (8 power phases), good looking RGB illumination, but the Strix doesn't have Debug LED for error troubleshooting and lacks one M.2 sockets compared to the Gaming 5 (triple M.2 PCIe 3.0 x4).

Or if you don't mind an inferior RGB, take a look at the ASRock Fatal1ty Z370 Gaming K6 (RM830) that has a stronger VRM (12 power phases) and comes with Debug LED.

I couldnt find the asus board at your price. I only manage to get it at RM950.
Or should i step up to Gigabyte Aorus Z370 gaming 7 ? Seriously difficult to pick.
No. Im not taking Asrock. I had a bad experience with warranty claims previously.

Gaming 7 is good, same tier as the ROG Apex. Previously it had VRM overheat issue but I heard it has been fixed in the new batch.

ASRock has two authorized distributors in Malaysia, SunCycle is good, AMT is bad.

This board rocks. I like it very much, affordable and comes with the Debug LED + ON / RESET button.

Welcome to the 5.0GHz OC club biggrin.gif
What's the exact model of your NZXT AIO cooler?
How do your CPU temperatures look like?

Kraken X52.

Temperature is awesome. I actually do mining with the CPU too so it's on full load. I get around 63C. Sometimes it peaked at 76C I think. GPU I throttle at 80C.

last week I update to latest bios for my mobo

I didn't realize it wiped my 5GHz (8700k) settings (my bad I didn't save it). I only realize it when I see my pc didn't run at 5GHz on load.

so I just play around again and include all values that I remembered. I'm not a extreme overclocker where by I can remember everything laugh.gif (learning from utube only... blush.gif )

after I key in everything and let my pc run. do some stress test, I found out my cpu speed wont go down to stock when on idle. what did I went wrong yea?

my cpu now stays at 5GHz all the time. but the temp around 40-45c on idle. on load it will go up to ~57c. speed remain.

Your CPU is running at 5GHz constantly even on idle because power saving features have been disabled in the OS and BIOS settings.

In OS, go to Power Options, select Power Saver power plan.

In BIOS, go to CPU Configurations, look for power management settings, enable Enhanced Intel Speedstep Technology (EIST) and C1E.

all are enable. this is what makes me wonder though...

and, is it normal for the temp to go up to 100c when doing Small FFTs test? I stop the test.

on Blend test, the temp seems normal for me.

edit:

OK, now I understand what u mean by OS Power Plan.

I change from High Performance to Balanced now.

Previously I changed to HP from Bal.

the speed now are at stock or lower on idle.

It's normal that Small FFTs being hotter than Blend test.
Small FFTs demand less memory than the Blend test, so the CPU spends more time processing data and less time waiting for data.

I think this can be explained here: https://superuser.com/questions/981466/in-p...0-for-al/981477

In most situations you will find Small FFT can easily pass the test but fails almost quickly in Blend.
I'd use custom Blend 1344K min/1344K max FFT with 90%+ RAM capacity stressed.

ok, prior to ur reply i did some googling and the results said about the AVX which are enabled in newer version of PRIME. Version 26.x seems no AVX, so that the temp tested using this version will produce lower temp reading. Im on v29 btw.

Regarding the test, on the current settings i manage to get stable on Blend with 1.25v. But when on Small FTTs, immediate BSOD..

I increase the v to 1.27, run small FTTs, no BSOD after several minutes BUT the temp went high 😅...

Whats ur advice regarding the test. Im just normal user with gaming, surfing net n doing some minor work on PC.

I believe you did not run Blend correctly like I suggested earlier, which is 1344K/1344K FFT (min/max) and with 90%+ RAM tortured.

Small FFT won't stress the IMC like the Blend does.

ok, I'm running the custom test now.

suggested time to test, 3 hours plus OR 10 minutes?

At least 3 hours, up to 8 hours.
10 minutes is seriously too short to find errors.

alright I've done my observation for several hours

I re-do all my settings and I start from 0

previously I'm using 5GHz preset by asrock but I edit few things;

max core ratio 50
cpu cache ratio 43
BCLK freq 100
AVX ratio offset Auto

Core voltage 1.25-1.30 (fixed)
Load Line Calibration Level 1

------------------

then I cleared everything but only edit these ^^ 6 settings, instead of using preset+self edit

--------

when running Prime95 - Custom 1344 Min/Max 90% RAM ;

on 1.25v, BSOD

on 1.27v, System Freeze

on 1.28v, I get worker stopped windows only 7/12 cores working

on 1.285v, only 11/12 workers working after 1 minute

on 1.29v, only 11/12 workers working after several minutes

on 1.30v, all workers working fine on 10 minutes test <-- this I need to test overnight because I do short test to see the workers failing or not upon increasing the V.

++ in CPU-z it shows 1.296v-1.312v during stress test and during idle.

owikh84, let say only one worker failed or stopped during the prime test, what should I do?

increase RAM voltage?

I read, some said increase the ram voltage

problem is, my ram is 2400MHz and 1.2v

I'm using crucial ballistix sport lt 8gb and single

--edit

right now I'm running at 1.3v 5GHz on normal usage.
