meg z390 ace OC help needed
« on: 20-January-20, 18:17:19 »

Hi, I'm a first time OCer,
 
 I have an i9 9900k, corsair 150i cooler, 64GB ram (4x16). I am trying to OC for the first time. I did the minimal bios changes:
 
 xmp, cpu ratio 50, cpu ratio mode dynamic, ring ratio 47, cpu core voltage 1.30v to 1.32V, Intel C-state disabled
 
 I have tested memory with memtest overnight in xmp mode with no cpu OC. Passed.
 
 I am using hwinfo64, prime95, and cinebench r20 to OC.
 
 Here are my results:
 
 Standard plus memory at XMP:
 Cinebench R20 : 4826, 4841, 4844 ~60deg
 Prime95 w/AVX2 10minutes : max 77deg
 
 5.0GHz, 1.30V plus memory at XMP:
 Cinebench R20 : 5192, 5165, 5187 ~86deg
 Prime95 w/AVX2 10minutes : FAILED (windows froze)
 
 5.0GHz, 1.31V plus memory at XMP:
 Cinebench R20 : 5171, 5159, 5180 ~90deg
 Prime95 w/AVX2 10minutes : FAILED (1 worker had rounding error after 7m) (saw thermal throttling at about same time)
 
 5.0GHz, 1.32V plus memory at XMP:
 Cinebench R20 : 5151, 5174, 5166 ~92deg
 Prime95 w/AVX2 10minutes : PASSED, (Ring/Core throttling after 7m, CPU package 100deg)
 
I'd like to know how to fully test stability from here and any other advice you can offer.
 
 Thanks!

There is no standard test for stability, it is up to you.

OK, but just looking for what some of the members of the forum do because I am pretty clueless.  First time doing this and worried about damaging the processor because of my ignorance.

Some run it hours with avx2, some without avx at all.
But today there are applications that use avx2, cinebench 20 probably does, just not so optimized like prime95.
I ran realbench, games run about the same temperatures/wattage and I don't get any bsods so I take it as stable.
Depends what are you going to use it for.

Would it be safe for me to run it for hours with AVX2?  It thermal throttles at 100C with my settings.

How long do you run realbench for and what settings?

I am using this for gaming mainly.

Thanks

I personally would not torture a CPU like that.

Set the "CPU Ratio Offset When Running AVX" to -2. It will allow the CPU to down clock and reduce core temperatures when running AVX work loads.

Set the H150i pump speed to maximum.

Are the radiator fans spinning at maximum when the CPU is under load?

Use these settings to run Prime95 without AVX:
Min and Max FFT: 1344
Select "Run FFT's in-place"
Disable both AVX2 AND AVX.

Extract the attached batch script to the root folder of Prime95. Use the script to start Prime95, the script will automatically detect WHEA errors while Prime95 is running. If WHEA errors are detected it will immediately close Prime95.

Basically it is always safe as thermal throttling protects the cpu from damage.
Personally I am not comfortable with temperatures higher than 85c.

Gaming like is maybe large fft with avx (not avx2) or no avx.

I only ran realbench stress test for 15 minutes, I stress tests with prime back in the days but I don't feel I need it now.

Thanks!  I will do this tonight.  I have not downloaded the corsair pump software.  I will do that too.  How will I know they are spinning maximum?  How long to run your test for?

Thanks again!

You can run the test for about one hour.

You can use Corsair LINK or HWiNFO64 to monitor the fan speeds.

Hi Krank.  Busy day at work.  Wanted to share what I got done tonight.  You have been so helpful!  When I ran prime previously, I never heard the fans rev
up.  After installing icue for the h150i and setting the modes, I could immediately tell when the fans were revving.  Here is what they look like in each mode:

CPU IDLE:






Running Prime with AVX (know you said not to do this, but wanted to see if it could keep the temps cooler now with fan running in balanced mode):


The CPU still hit 100deg, but only 2 cores throttled this time.  Killed it after 10minutes.  Looks like fans were running full speed.  Looks like the pump was
not running full speed.  Guess that needs to be set to extreme.  Should I run the fans in balanced and pump in extreme always?

I have a concern though.  Look at my 3 other case fans during the run of prime with AVX:



It looks like they never changed speed.  These are connected to the ace MB.  How do I set those up to rev up under load?

This is all I could get done tonight, but will continue tomorrow.  Thanks so much for your advice!

Below is a pic of my Setup. The case fans and the radiator fans are all connected to the motherboard fan headers and controlled by the customized BIOS fan profiles. I don't have Corsair LINK or iQUE installed. I only used Corsair LINK to set the pump speed to Extreme and set the pump LED's to the liquid temperature profile. I then saved the settings permanently to the pump's onboard memory and uninstalled Corsair LINK. The pump LED's are set to change according to the liquid temperature, it is only possible to do this with Corsair LINK. iQUE does not allow this and needs to be installed and kept running in the background to have the liquid temperature active.

The USB driver is still needed to monitor the liquid temperature with HWiNFO64 so I saved the H150i USB driver by exporting it using Command prompt.
Code: [Select]
dism /online /export-driver /destination:C:\DriverBackup
The H150i USB driver can be manually installed with Device Manager. I make my own customized Windows 10 setup media so I slip-streamed the USB drive into the install.wim, after I've done a clean Windows install I can immediately see the liquid temperature with HWiNFO64 without installing LINK or iQUE.

The three radiator fans are connected with splitters to the same fan header. The three font intake fans are also connected with splitters to a fan header.



You need to manually set the fan profile settings in the BIOS, click and drag the blue dots:

Click on Hardware Monitor


These are screenshots of my preferred fan settings:

VRM Fan.


Radiator Pull fans.


Radiator Push Fans.


Case Rear Exhaust Fan.


GPU Rear Exhaust Fan.


Front Intake Fans.

Hi Krank,

Your PC looks AMAZING!  I have set the AVX offset to -2.  I have set the case fans smart curve in bios (they basically go full speed at 60C).
I re-ran prime with AVX, just to see what would happen.  Pretty much at the 7m-8m mark the temperatures jumped between 90-100 and I insta-killed it.
So, even with AVX offset at -2, it still gets too hot.  Is that OK/Normal?

Next I ran Prime using your batch script and settings.  CPU Package temp maxed at about 83C during the 1 hour I let it run.  No WHEA errors.

What should I do next?

What is the idle and load temperatures for the liquid? Please post a full screen screenshot of HWiNFO.

Is the radiator front or top mounted?

What is the make and model of your PC case?

Hi Krank,

Here is an idle screen shot of HWinfo:



My radiator is front mounted.  Here is idle temps:



Ok, I left that prime run running after it hit an hour.  Came back 2 hours later and my PC had shut down.  Not good.  Don't know what happened.

:(

Hi Krank, everything ok?  Keep checking this thread looking for guidance.
Does your test indicate the OC is stable?
Do my temps look ok?
Should the cpu still hit 90C+ with AVX offset at -2 when running prime w/AVX? 
Any thoughts on why the PC shutdown when running your prime recipe?  I noticed the screen saver shut the lcd off when prime was running.  Should that happen?  maybe it tried to goto sleep after 30m, but I would think that shouldnt happen?

Anyways, hope all is good with you and thanks so much for the help you’ve given me.

Hi,

Did you use my batch script to run Prime95?

The CPU core temperatures will always be much higher when running AVX tests. You can increase the AVX offset to -3 to see if it equalizes the temperatures with non-AVX load temperatures.

What is the room temperature where the PC is standing and what are the max CPU temperatures when gaming?


Have you tried to customize the active Windows power plan to extend the screen/sleep timeouts?

Yep, i used your script. No errors.  I checked the prime folder and there is a log there. The time the PC shut down while running your recipe, there were no errors detected.  Is it possible VrMs got too hot and made the pc shut down? My room is 22C.  I have not even gamed yet. Trying to get PC stable.  How long would you consider running your test for to be stable?

I can turn off LCD shut down and PC sleep and see if I can run your test over night?

You can use HWiNFO to log the Sensor readings. I personally don't run the tests longer than one hour.

So, since it ran for more than hour, would you consider it stable?

It is for you to decide if it is stable or not. Stability is never guaranteed when overclocking. 

If you want to you can run the Linpack Extreme benchmark to confirm if your system is stable or not.
https://www.techpowerup.com/download/linpack-xtreme/

Select 2. Stress Test
Select 5. 10GB
Enter number of times to run Linpack (1-10000): Press 5
Press Y to use all available threads.
Press N twice.
Then press any key to continue.
Press CTRL+BREAK anytime to abort.
Use HWiNFO to monitor for WHEA errors.

Going to try that. I wanted to see what would happen if I went back to default BIOS (no OC) and tried Prime w/AVX.

The temp's never got over 70C.  Maximum Vcore was 1.2V.  LCD Shut off after 10m and computer went to sleep after 30m.  Strange W10 goes to sleep when Prime is running.
Anyways, let Prime w/AVX run for 50m total.  No issues.  Computer resumed from sleep just fine and continued running prime.  All cores were running 4.7GHz.  Makes me wonder why I am bothering for 300MHz more.
Here's the screenshots:

I think I am starting to understand the reason I am over 90C 7m into Prime w/AVX (AVX offset -3 now).

Look at HWINFO in previous post and this one.  Core frequency is the same.  Voltage is less!  So, the only difference is Ring/LLC clock!  It's 400MHz more and seems to blow up the temps!

I must be seeing in reverse because I see 0.23v more.

Second you need to compare something measurable e.g. linpack and compare gflops, or cinebench.

Where do you see the .23V more?  I’m probably looking in the wrong place.

yea, i was looking at the wrong row.  I ran the Krank prime recipe and was able to reduce the Vcore to 1.230V and still pass.  I then ran realbench stress test and the temps were <80C the whole time.  Ran it for an hour.  Passed.
