Server RAM compatibility questions

DaShesano · July 7, 2016

Hi all,

I recently bought a Supermicro SuperServer SYS5019S-M barebones unit, and my only concern currently is which RAM I should put in it. I was wondering if I should put generic Kingston valueRAM server memory in it (This kit to be exact) (or even this Kingston XMP memory kit) as it is relatively generic and isn't specified for use in any particular system. My only concern with running this memory is that it is not on the tested memory list, and I am wondering if there is any harm (to my board, wallet or otherwise) in straying off the memory models listed in the tested memory list for the motherboard (Supermicro X11SSH-F), as the memory on the tested list isn't exactly the cheapest and I'm trying to keep costs down for this build.

Thanks.

Using different memory probably wouldn't harm the board, you'd more likely run into issues with compatibility. I would suggest just going with the supported, though I don't have any hands on experience with these boards.

Generally no most ram will be fine, when it starts to matter is when you go over 64GB per CPU then you have to make sure you get the correct ram with the right voltage/rank/speed/ecc/reg.

Not all memory configurations have the same supported maximum amount that can be installed or speeds. The motherboard manual will have a support matrix table on it showing what the maximum number can be installed, max size per module etc for each voltage and rank. IBM/Lenovo and HP have these in their manuals and I would expect supermicro too as well.

Also the first kit you linked to is ECC Registered ram (Best) and the second is only Non-ECC Unregistered (Not for server use but does work).

The different types of ram are:
