Hello,
I have a new Gigabyte Z390-m Board and 9900k which 've ben dialling in my overclock.
On the very last session before settling on my settings I had a crash/reboot and I'm sure something is wonky with my board now.

If i try to use windows 'Winsat' to test performance it says "Error: Cannot Measure Time Stamp Counter (TSC) Frequency" and does not proceed.
I suspect this may be because of a corrupted MEI?

I have powerd down, taking battery out of board - I have downgraded BIOS - then reflashed newest BIOS with no improvement to situation.
If i try to flash the newest MEI it says:

Error 63: Unknown or unsupported hardware platform.

This is using FWUpdLcl64.exe version 12.0.35.1427 to flash the 12.0.35.1427.bin

I was hoping the experts of WinRaid may be able to help please.

Thanks

Thanks Plutomaniac.
Ok so I downloaded tools package release R17.
MEinfoWin64 diplays the following:

FW Status Register1: 0x90000255
FW Status Register2: 0x06F10506
FW Status Register3: 0x00000020
FW Status Register4: 0x00004004
FW Status Register5: 0x00000000
FW Status Register6: 0x00400000
CurrentState: Normal
ManufacturingMode: Enabled
FlashPartition: Valid
OperationalState: CM0 with UMA
InitComplete: Complete
BUPLoadState: Success
ErrorCode: No Error

SPI Flash Log: Present
Phase: ROM/Preboot
ME File System Corrupted: No

FPF and ME Config Status: Not committed

Looks like no corruption, but I cant seem to get the TSC frequency/clock to work?


Thank you for help

Set bios default and stress test with prime. if that pass then overclock is the culprit....

Hi XGen,
I've tried resetting to defaults, pulled board battery, reflashed BIOS - no matter what the TSC clock seems to have disappeared.

The system still seems to function ok, albeit perhaps not as smoothly as before. . .

So for anyone who is reading this that has had the same problem with the TSC clock disappearing.
The problem was definitely the Gigabyte board I am using. GByte bios is a bit more flaky than Asus from my experience.

Despite clearing Cmos, removing battery, re-flashing bios the problem persisted.
I tried another overclock setting, pushing the OC a bit higher and the OC failed with a hard crash.

Upon rebooting the board didnt just say OC failed, but had done its own recovery saying it had cleared Cmos and then, lo and behold, the TSC clock was back.
You would think a manual power down and cmos clear would have done the same thing, but the GByte bios is a bit flaky if you have some crashes whilst finding your stable OC - it seems.

Many thanks to PlutoManiac for his efforts in his excellent Management Engine Guide - which enabled me to update the IME on my board.
