Memory to use in Lenovo TS440

[benitz8]

Hi. I just got a Lenovo ThinkServer TS440 barebones server with only 4GB ECC UDIMM pre-installed.

I have some questions:

1) I would like to confirm that UDIMM just means Unbuffered DIMM, which means I can just buy any DIMM memory that is unbuffered/unregistered.

2) I would like to put in 16GB more (either 1x16GB or 2x8GB). Can anyone suggest what brand/model I should put in? I am looking at Corsair CMZ16GX3M2A1600C10 but that is Non ECC. Am I right that this cannot be mixed with the 4GB ECC the server came with?

3) This unit I will not really be using as an actual server. More like a powerful desktop. In this case, would having ECC memory be important? Because if I am unable to buy a ECC Unbuffered DIMM, I might just buy the 16GB Non ECC and remove the built-in 4GB.

I would appreciate any comments you give.

Thank you in advance.

1) Yes, UDIMM means Un-buffered Dual In-Line Memory Module.
2) Corsair is a great brand, so you should be good with those, and you can mix ECC with Non-ECC, but you really should avoid at all costs. It can cause some problems, especially if you use them in the same bank. Some boards do require ECC memory, so if you have some spare Non-ECC memory lying around do try before buying Non-ECC memory.
3) And no, you really don't need ECC memory, especially if you are just using it as a workstation. Memory technology is much more reliable now than it was a few years back, so the need for error correcting memory isn't so high anymore.

I actually erred on the side of caution and went ahead and purchased the Crucial CT2KIT102472BD160B. Its ECC UDIMM so its perfect for the requirements of the TS440.

Some more questions thought:

1) Will I have a problem running the Crucial CT2KIT102472BD160B (2x8GB) together with the factory supplied 4GB ECC UDIMM (I don't know the brand/model as the unit hasn't arrived yet)?

2) If I do put them all together for a total of 20GB, does it matter which modules I put in which slot? If it matters, can you tell me which to put in which slot.

Thanks in advance.

The new memory shouldn't cause a problem, as long as you keep the sets in different channels from one another (put the new kit in the green slots and the original memory in the blue slots).
