Server RAM configuration
Hi All,
I have a ESXi host which I was looking to upgrade the memory on.
Is there a way to find out which ram type it requires as on the vSphere it just indicates chip type: DIMM
When I tried installing RAM, error received: Only 2 DIMMs can be installed on a channel with UDIMMs
Server: HP Proliant DL380p Gen8

@Ronnie-Wong Thanks for the reply.
Do you know how much RAM the server can have with only 1 processor?
I'm not sure what you mean. The CPU will be able to access the RAM that is available on the motherboard. So if a motherboard will support 768 GB of RAM and it has 2 CPUs, both CPUs will have access to 768 GB of RAM if that much is installed. If there is one CPU with 768 GB of RAM on the board, it will be able to access up to 768 GB of RAM.

@Ronnie-Wong I'm not sure if the server can handle the maximum RAM with only 1 processor which has 6 cores per socket?
Could this be because of the RAM configuration?
Please advise
@Waqkas-Ahmed I think it’s 768GB max so would be half that as with one processor you can only use half the DIMM slots obviously depends on size of DIMMS used and type
I think you will have to look up specification on your server to see how that works. Probably if you needd more direct help reach out to HP support directly and they can let you know.

So is there a minimum amount of ram for 2 CPUs or 1 CPU? I don't know. I recommend you reach out to HP support to ask them directly if you're not able to see all 768 GB of RAM.

DL 380p Gen8
he ProLiant DL380P G8 can hold up to 512GB (16 x 32GB) 1600MHz for ECC Registered system memory and up to 768GB (24 x 32GB) 1866Mhz for Load Reduced Server Memory. Depending on the memory configuration and processor model, the memory speed may run at 1333MHz or 1600MHz registered DDR3 DIMMs
You start by identifying the RAM you are currently using in it. You need to match to it. How much ram do you need is based on what you are running under VMWare. You have a single CPU. I would spend the money on the second CPU instead of RAM. VMWare will turn them into vCPUs.
I have an HP DL320e Gen8 with dual 6 core Xeons. VMWare sees them as 24 vCPUs. You will find having more vCPUs allows more VMs to install and run. Next, I don't use non-HP ram in a HP server that came with memory unless you are going to remove it. I match memory on servers. HP memory is not expensive on Amazon. I have 96GB of RAM for my Ubuntu VMs and Cisco VIRL.
