Upgrading memory

[RodWms]

I simply need to know which memory and how much to buy for an upgrade on the HP Slimline 270 a011 and the specs page are no help because there's nothing that comes up in searches using this info:

• Single channel (2 DIMMs per channel) memory architecture
• Two DDR4 UDIMM (240-pin) sockets
• Supports up to PC4-19200 (DRR4-2400)

  NOTE: 

  Might be limited further by the processor.

• Supports 2 GB, 4 GB, and 8 GB DDR4 UDIMMs
• Supports up to 4 GB on 32-bit systems

  NOTE: 

  32-bit systems cannot address a full 4.0 GB of memory.

• Supports up to 8 GB on 64-bit computers

The bios in my unit is very basic.  Actually there is no settings so the memory would either work or not and you cannot really adjust anything.  I put in 3200MHz CL16 memory into the 4700G system and it did not like it.  So I replaced it with a Crucial CL22 timing that was similar to the OEM and that runs fine.  You can look at the memory that is in the system and reverse lookup to find memory that is compatible perhaps.  Passmark / HWINFO should read out the model number.

If you launch a Power shell session.  (Start->type power shell->click on the Windows Powershell App)

PS C:\Users\larry> Get-WmiObject Win32_PhysicalMemory | Format-List *

It will list out 

Name : Physical Memory

Google the partnumber should get you close.
