Type of memory installed?

[smithse79]

I have a Dell CS24-SC with 8GB of RAM that I want to upgrade. Is there a way to find out which type of ECC memory is installed without having to tear into it and physically look at it and look up a part number? OpenManage and the BMC just say ECC DDR2. This is an old cloud server so the service tag obviously isn't on the Dell support site either. It's running Centos 6.5

Try this: Linux: Check Ram Speed and Type

It's funny you mention that, I just found that utility tonight. The only mention of ECC type in anything I've been able to find is multi-bit ECC. I'm just not sure what that means. I'm assuming this is unbuffered ECC but

I'd just open it and look

Software may report running speed not actual speed, not sure about complete model #s, etc...

Thats what I'm coming to realize. However, all of the documentation I'm finding online shows that these servers run registered ECC. I can get decent amounts for cheap since it's DDR2 so it won't hurt to pick some up

I'm not sure about DDR2 but the single, dual, quad rank may affect your total memory/stick capacity recognized by your motherboard.

My advice, don't willy-nilly buy DDR2 ECC RDIMM. I'd crack it and be 100%. Just talking from experience

but... but... I don't have a rack yet and it's at the bottom of a 3 server pile...

LOL Like me, too many chassis in the way to get other projects done.

Today I hope to eliminate my stack like yours, and push forward hehe

If you're running Windows, CPU-Z has never steered me wrong. CPUID

Nope, Centos

Try a utility called dmidecode. On my box with decent ram, it even reports manufacturer/part numbers etc.

Here is a sample:

You might also like to try lshw; both that and dmidecode should be able to report the exact DIMMs you have installed but unsure if RHEL/centos includes both of these by default. IIRC `lshw -class memory`.
