Label decoder
The following should be used to understand key attributes about the type of memory that is loaded in a system. When looking at the DIMM label, you should see the following format:
gggGB pheRxf PC4v-wwwwaa-mccdt-bb
? ggg = Module total capacity, in gigabytes
? phe = Number of package ranks of memory installed and number of logical ranks per package rank.
? p = # of package ranks installed
? h = DRAM package type
? e = Logical ranks per package rank
? ff = Device organization (data bid width, e.g. x4, x8, x16)
? PC4v = Indicates that this is a DDR4 module and the supported component supply voltage
? PC4 = operates at 1.2V
? PC4L = operates at a lower voltage TBD
? wwww = Module Speed in MHz pin
? aa = SDRAM speed grade
? m = module type
? U = Unbufered
? E = ECC unbufered
? R = Registered
? L = LR DIMM
? cc = Reference design fle used in this design
? d = Revision number of the reference design used
? bb = JEDEC SPD Revision Encoding and additions level used on this DIMM
