Question "WHEA_UNCORRECTABLE_ERROR" BSOD when running 4 cores ?

[Rockya]

Motherboard: Asus Prime Z270-A
CPU: Intel i7-7700K

Running the i7700k with BIOS set to ALL cores boots fine but causes BSOD WHEA_UNCORRECTABLE_ERROR, after a few minutes of normal browsing, file open etc.

If I select 3 cores in the BIOS it runs great very stable, and fast. Never any BSODs.

All other settings in the BIOS are defaults, no over clocking, no tweaking at all.

Running the Intel Processor Diagnostic when 3 or 4 cores active says CPU 1 passes. Max temp when running is 78 degrees on CPU and 79 degrees on package and cores. Data from CPUID HWQ Monitor.

I have tower air cooler.

Any suggestions on how to get all 4 cores running and stable? I want to run DAW music software and plugins which are demanding.

Many thanks
Rocky A

This utility might give you a bit more detailed info about cores, voltages etc.

Have you tried slightly undervolting cpu to see if all 4 work?

Not tried undervolting that but makes some sense. I have to set non turbo on boot to allow PC to boot up on 4 cores. So I think it could be something to do with voltage.

Also, at start up, the PC often switches on , then immediately off and then back on again.

I have just downloaded the intel extreme tuning utility. I will restart now and report back.

Thank you.

Hi KingLoki

I tried to cut an paste in the extreme tuning page but it wont paste.

In compact view there is a "power and current limits Optimized" banner. If I hover over that it says "Active and default values for power and current are already at or above the optimized limits set by this tool.

The bench mark is 1391 using 3 cores. Not tried 4 cores yet as it usually just hangs after 5 mins.

In advance view the screen is blank. No tuning controls appear.

That's strange, you should be able to manage core voltages etc easily.

Make sure your chipset driver and Intel Management Engine (IME) driver are the latest versions.Visit the motherboard manufacturer's official website to download and install the latest drivers.

It is very odd.

1 Asus Z270-A running on latest bios, namely 1302
2. Uses Intel® Z270 chipset
3. All drivers downloaded and up to date on Intel driver and support site
4 Windows all updated via Windows Update
5 Uninstalled utility and re-installed. About to restart!

Same issue. Extreme Utility shows power and current limits optomized. Nothing showing in advance view.

Try running it as Administrator.

 

[KingLoki]

Try msconfig to not load startup items.

Type "msconfig" (no quotes)
Click "Selective Startup"
Untick "Load Startup Items"
Click "Apply" then "OK"
Then restart the computer and run the utility as administrator

 

[KingLoki]

If the msconfig suggestion doesn't work then go back in and re-tick it and Apply>Ok, then restart to get back to normal config.

Tried the above. Still no options in compact or advance view.

I downloaded the Intel Management Engine and ran setup. Does it just load drivers? There is no Intel Management Engine utility to run. Is that correct?
