That would be the Intel Management Engine (IME) software, that provides among other things communication between the board's firmware (UEFI/BIOS) and the OS. |
Seems there is support for IME in Linux
Whether it is in use by any application I don't know
I could find the device file /dev/mei0

DDR4 memory at 3600 will be really, really pushing it for an X99 system, and certainly 32GB will be extremely difficult to maintain at that speed. I really should say impossible. As you have already seen, at a memory speed of 2745, only two of the four DIMMs were detected. That indicates the memory speed and/or the latency settings and DRAM voltage are not optimally set. |
What I can do is run the 3600MHz DDR4 at lower speed and thus be able to set lower timings.
I am now running at 2400MHz with timings 15-15-15-32 CR2. Stock timings where 17-18-18-35
Though I was hoping to get the memory up to at least 2800MHz, hopefully 3000Mhz, and with all 4 modules.
There is a reason I choose X99, and that was 40 PCI lanes. I knew I wouldn't get as good memory speed as with Skylake. but I know of some people who have gotten an X99 running with 3200-3400MHz DDR4 (though on ASUS. They said ASUS where better than ASRock when it came to getting higher memory speed on X99).
