Dell R620 Dimm dismatch Memory

Hello

You can view the memory population rules/guidelines in the system support manual. It is on the support page of the server. In general, you should populate larger and higher rank modules first.

If the available memory is showing correctly everywhere except the OS then the OS may be limited to 16GB. I suggest reviewing specifications for your OS to see if there is a memory limit.

Thanks

Hi Daniel,

I can see all the 48GB of memory ram from the OS, and I'm sure the O.S. cloud use it ( I have the same version on server with 500GB of ram and haven't had any problem).

The only difference is that this one has different Dimm:

four of them are 4GB Dual Rank, while the other four are 8G Single Rank.

Regards

No, those are just examples or sample configurations. There are supported configurations that are not listed in the manual.

If you are unable to find the reason that the memory is limited then I suggest posting details. If you want someone to review your configuration to find what might be limiting the available memory then you need to provide that information.

Hi Daniel,

What kind of details do you need?

Here are the specs of the Ram:

• 4 Dimm Dual Rank DDR3 4GB@1333MHz Manufacturer: Hynix Semiconductor (Original Speed: 1333)
• 4 Dimm Single Rank DDR3 8GB@1333MHz Manufacturer: Samsung (Original Speed: 1600)

The make and model of the memory modules, the make and model of the CPU, and the version of the OS. You will need to provide details about the OS version, if you just say it is something like server 2008 that is not very helpful. Provide information about the specific version you are running.

Hi Daniel,

Here are all the Specs:

• OS: Proxmox VE 5.2-5 - Based on Debian 9 (stretch) 64bit, Kernel: 4.15.17-3-pve
• Ram:
  • 4 Dimm "Samsung" SingleRank 8GB@1600
  • 4 Dimm "Hynix Semiconductor" DualRank 4GB@1333
• CPU: 2 x Intel Xeon E5-2620 0 @2.00GHz
