I've set out to build a server and I might have ordered the wrong RAM.

The motherboard I'm using is an ASUS KGPE-D16. In the specifications, it states that I can have 256GB of RDIMM or 64GB of UDIMM. The RAM I bought is consumer, CORSAIR Vengeance CMZ32GX3M4X1600C10. The memory format for the RAM is just "DIMM".

The question I have is what type of DIMM is my RAM? RDIMM or UDIMM? Or is it neither, meaning it won't be supported at all?

This question came from our site for system and network administrators.

The memory you linked to is performance memory (XMP extreme profile, heat spreader, ...). As such is is almost guaranteed to be unbuffered. (Buffered/registered memory is always slower). – Hennes Feb 5 '13 at 1:35

Unless you are specifically setting out to by registered RAM, then chances are you've bought Un-Buffered RAM. Un-Buffered RAM makes up the majority of consumer-level RAM available, and registered RAM is typically plastered in warnings it's not for most motherboards.

So there is no "third type" of RAM just known as DIMM? – NessDan Feb 5 '13 at 1:35
No. DIMMs is just the form factor. Registered/buffer, unregistered/unbuffered, and fully buffered are different types (which can come in the same form factor). – Hennes Feb 5 '13 at 1:36
@NessDan - DIMM is just a form factor, it means "Dual In-Line Memory Module", as opposed to a SIMM "Symmetrical In-Line Memory Module" (from the 90s). There is also FB-DIMM ("Fully Buffered Inline Memory Module"). Back in the early days of the DIMM you could get away with just calling it a "DIMM", but these days, it's just referred to as a form factor/packaging. – Mark Henderson Feb 5 '13 at 1:36
Thanks guys, so you're for sure that my RAM is UDIMM? (If this is the case, I need to return it right away.) – NessDan Feb 5 '13 at 1:47
Yep, that RAM is definitely UDIMM. – Marcus Chan Feb 5 '13 at 2:06
