TsysMemorytypes & DDR4

[adrichap]

I want to find all machines on the network with DDR4 RAM in them, but TsysMemorytypes doesn't have an entry for DDR4, so consequently I have a lot of assets with a RAM type of other or unknown.
Is there something I can do to scan for this, or does it require a new version?
Version is 5324

According to DMTF, DDR4 is type 0x1A, decimal 26.

But you need :

a) A machine with SMBIOS version 3.0 to report it.

b) That Microsoft updates the Windows WMI class with that information.

I don't have a DDR4 machine yet to test it, my latest and newest machines are still on SMBIOS version 2.8, so I cannot help there...

What I can suggest is that you do a report with the mainboard model or machine model that you know for sure are DDR4. Unless you have a very heterogeneous shop (I have, so I can relate to that), it should not be very hard.

Then unfortunately we have to wait until Microsoft fixes this.

All machines with DDR4 report memorytype 0

Which number do you see in the "memorytype" field?
I see that the Microsoft documentation does not included DDR4 but it's probably already included in a number higher that 25.
