Because 2620 V3 supports DDR4 up to only 1866MHz.

Hi guys!
A question for the most experienced ones:
After many successful attempts with E5 v3 xeons, I'm currently struggling with a quad E7 V3 QS system.
Microcodes removed from BIOS.
I can compile freecableguy's efi latest driver with the 306F3 microcode and it runs at bootup just fine.
Sets...
I am simply using the uefi program on my z10pa-d8 like on all the other boards.
Delete the ucode, and add the uefi driver from uefi shell with the bcfg command.
You can remove the microcode like from all the other BIOSes.
For programming you're going to need a hardware programmer. CH341 did not work for me with these 128Mbit chips, but TL866 did.
Try to use AFU or FPT. There are many tutorials. But it's not 100% that they will work.
The best method is using an external programmer like TL866 or CH341. Clamps do not work for me, I always solder out the eeprom. It's not that hard.
You must have disabled the CPU power management in BIOS that results in static base clock on all cores, which is 2000MHz for your CPU.
Or the turbo boost is disabled in bios.
There are some combinations of the powermanagement settings that can cause this.
I suggest resetting the bios to defaults.
Hmm.. OK, I'm going to try that.
But what do you mean "when iddle the CPU spread to 107mhz" ?
You mean the BCLK only goes up to 107 when the load is low on the CPU?
Is that because of TDP limit, or something else.
Can you set 107MHz BCLK under all core 100% load?
