Hello;
I bought the X570D4U-2L2T last week with Kingston FURY Beast DDR4 (KF432C16BBK4/128) 128GB memory. I tried to configure this memory on the MOB but only 64GB is detected.
I tried putting only 2 memory stick at once (A1+B1) (A2+B2), and both worked normally. I double-checked the bios and BMC versions and they appear to be up to date with the information provided in he website.

BMC Firmware version : 1.20.00
Bios Firmware version: P1.40
PSP Firmware version: 0.14.0.2A
Microcode version: 0a201009


My Config:

MOB : X570D4U-2L2T
Ram: Kingston FURY Beast 128GB (4x32GB) 3200MHz DDR4 CL16 (KF432C16BBK4/128)
Processor: Ryzen 5900X

Do I miss something?


Thanks

the mem.channels are A & B. if A1 & B1 works, both channels are alive.
check one pair in A1/B1 then the other pair in A1/B1.
if both pairs give 64GB all DIMMs are OK.
reset cmos after changing memory size or memory type.

the kingston are double ranked, set memory frequency to 2400

without XMP the Kit needs 2400 setting, looks 2666 and 2933 don't work without XMP.
i had always problems with Kingston and the Plug&Play Jedec profiles.

FACTORY TIMING PARAMETERS
• Default (JEDEC): DDR4-2400 CL17-17-17 @ 1.2V
• XMP Profile #1: DDR4-3200 CL16-20-20 @ 1.35V
• XMP Profile #2: DDR4-3000 CL16-19-19 @ 1.35V

you have 64GB(2*32GB) installed ?
and the BIOS shows 64GB.
if you have 4*32GB installed, your Memory channel A is dead.

if you get the memory to run you should know the following fact:
this board can not deliver 1.35V to the memory, even if you can adjust that in the BIOS the DIMMs still are supplied with only 1.2V

Hello,

Thanks a lot.

The issue has been resolved.

For the moment, everything is great since I purchased the KSM32ED8/32ME.
