[AMD][Intel] Non-binary DDR5 #511
Description
DDR5 Query
-
To decode the 24GB or 48GB DIMM geometry, can anyone dump some registers ?
[AMD] Zen 4 or 5
- 7950X: DIMM 24-48 GB
- You will have to compile the zencli
# Compile the tool
cc zencli.c -o zencli- Run it as root on the first four channels to dump the memory controller configuration
# channel 0
./zencli smu 0x50100
# channel 1
./zencli smu 0x150100
# channel 2
./zencli smu 0x250100
# channel 3
./zencli smu 0x350100
- In the
DdrTypebits-field I expect to find some new DDR5 type values or something in theReservedpart
[Intel]
- I still have found no IMC register about non-binary DDR5
