Z440 memory compatibility

[Echeese63]

I recently acquired a Z440 motherboard very cheap, and was going to assemble a budget gaming rig out of it, but from what I've read, the motherboard only accepts ecc RDIMMS.

So I was wondering if these Kingston sticks would work?

read the HP z440 "quickspecs" for what memory types are supported on this workstation

I did, but it only lists the hp part numbers, nothing from any other brand

erm.........right not sure what document you looked at

go down to "memory"...............................

Most of these good memory suppliers provide a "Memory Finder" utility on their web site:

Memory Finder - Find the Right Memory - Kingston Technology

Then,  HERE 

The memory shown above... note that they provide 32, 16, and 8GB memory, but also the 4GB sticks

from elsewhere will work fine in the Z440 assuming you are choosing properly.

The memory sockets layout on the motherboard for a Z440 are different than for a Z640... learn that difference..  In the Z640 running a single processor you will be wise to run bigger sticks.

HP has moved to faster DDR4 RAM for this generation of workstation even if the processors will not be able to run at the fastest speed that the memory could run at if it had a faster processor to work with... it is cheaper to buy faster ECC Registered DDR4 memory than slower DDR4... go figure!
