Question 1

I bought this for my server with a xeon processor.
I noticed the package says 'workstation'
will this work, or do I need server memory?

Accepted Answer

Depends on what Xeon you purchased; the key difference is that some Xeon's use Registered RAM and others use Unbuffered RAM. I used this in a server, but that's because I used it with the Xeon E3-12XXv3 which requires Unbuffered RAM. The 1200 series Xeon's are often used in workstations or for small, low-power servers and that's why the package says "workstation."

Check your motherboard to determine which is used. Unbuffered Xeon's are limited to two 8GB DIMMs per channel and dual channel for a total of 4 DIMMS and 32GB. IIRC, only the 1200 series use unbuffered memory; all the other Xeon's should be using Registered memory. You can't mix them up, you must use the correct type.

Registered RAM puts a "signal driver" to act as a buffer on the DIMM, which allows for more DIMMs per memory channel and more capacity (GB) per DIMM. Of course, registered RAM has slightly worse latencies (actual, not the integrated circuits specs which are the latency numbers you see listed when purchasing memory).

Question 2

Is this ram dual channel or quad channel?  If it is quad will it still be compatible with my motherboard witch supports dual channel?

Accepted Answer

The dual channel and quad channel barely make any difference, usually if the memory runs then it's good enough. Since you asked about channeling, just want to make sure you are using this for a server motherboard with ECC compatibility, or even check the motherboard manufacturer approved list. Server memory is sometimes very picky.

Question 3

I previously purchased Crucial registered memory sticks (CT8G3ERSLS4160B) and had a POST alert to lead me to believe that the were incompatible with a UDIMM slot (it is my first time building a server).

Were those previous ones in fact incompatible, and would these be compatible with my ASUS P9D-V mobo instead?

Thank you.

Accepted Answer

These are unbuffered ECC.  Are you sure you want ECC for your server motherboard...you don't give the model you are working on.

I'm not sure how the P9D-V motherboard would take ECC RAM, it is certainly not designed for it.

On modern motherboards the memory controller is on the CPU, so the compatibility of the memory will depend on the CPU.  For example, some SuperMicro server motherboards will accept ECC RDIMMS with a Xeon CPU, but not with the i7 CPU.  There are so many variables that it is hard to tell without more information.

Question 4

Does this memory work with Lenovo TS140?

Accepted Answer

Go to crucial's website and use their advisor tool

Question 5

Given this is 1.35V ram, will it work in HP Proliant ML10 v2 (with core i3-4150 processor) that came with 8GB 1.5V ram?

Accepted Answer

I'll offer two answers.  First, never mix memory of different characteristics or from different manufacturers.  However, if your system supplies 1.5v it will clearly supply 1.35v.  I would want to see the Crucial memory listed as supported on the HP's documentation.  And, it may matter which slots are used.

Question 6

is this with the HP smart-memory certificated?

Accepted Answer

No, HP Smart-Memory Certificates are a way for HP to mark stuff up. Crucials website has a compatibility toll, use that and forget HP.

Question 7

Does this memory fit Dell PowerEdge T20?

Accepted Answer

Yes

Question 8

is this memory compatible with a dell poweredge t410 server?

Accepted Answer

Crucial lists only their CT2720887 Unbuffered ECC RAM as compatible with the Dell PS T410.  However, I have used this RAM in Dell PS and HP Proliant servers as well as multiple SuperMicro based "built" servers without complications and is normally my "go to" Unbuffered ECC RAM, FWIW.  So officially, no, unofficially, very likely.

Question 9

It works with the dell power edge r210ii processor xeon e3-1220?

Accepted Answer

It worked with that processor for me...

Question 10

Does this memory run with lenovo thinkservier ts140?

Accepted Answer

I use it there.
