I happen to have an ASROCK X99 Extreme 4 that has an i7-6800k and the exact same memory configuration (128GB) using the exact same DIMMs as the other system.

I tried the new XEON in this system as well, and got the same result.

I'm gonna return the CPU. :(

Note that it was brand new in the box so cleaning shouldn't have been necessary.

Thank you.

Double check your socket and the contact pads on the CPU. Missing memory channels
99% of the time are caused by improper contact between the CPU and the socket pins.
Carefully clean the underside of the CPU with a cotton swab and isopropyl alcohol.
If that doesn't resolve the issue then the only other potential cause is a dead
IMC on the CPU itself, it's rare but accounts for the remaining 1%.]]> Wed, 07 Jul 2021 13:47:43 +0000 https://forum.asrock.com/forum_posts.asp?TID=19214&PID=89180&title=x99-extreme6-3-1-xeon-upgrade-failed#89180 https://forum.asrock.com/forum_posts.asp?TID=19214&PID=89173&title=x99-extreme6-3-1-xeon-upgrade-failed#89173 Author: docdrow

Hi All,

I have an X99 Extreme 6/3.1 with an E5-2630v3 and 128GB of non-ECC DDR4 working fine.

I attempted to replace the CPU with a newer E5-2683v4, but it only recognized half of my memory (64-gig).

When using the E5-2630v3 it shows "quad-memory channel" on the CPU info screen, but only "dual" when using the newer CPU.

Anyone have any ideas? I'm on the latest 3.5 BIOS.
