Understanding Supermicro memory

[pjuser115]

Does anyone know what the model numbers mean on Supermicro memory chips? Is there something I should look for as far as faster or newer or a series that I should stray away from?

MEM-DR316L-CL01-ER18
MEM-DR316L-CL02-ER18
MEM-DR316L-HL01-ER18
MEM-DR316L-HL02-ER18
MEM-DR316L-HL03-ER18
MEM-DR316L-SL02-ER18
MEM-DR316L-SL03-ER18
MEM-DR316L-SL04-ER18
MEM-DR316L-IL04-ER18

I can assume that SL04 is newer than SL02? but does any of that mean anything? They are all the same price.

I have a AsRock Rack EP2C602-2L+/D16 which takes 16 x DIMM DDR3 1866 / 1600 / 1333 / 1066 LR / Registered / ECC / UDIMM, max. 512GB. I plan on having 4 or 6 of the DDR3 1866 16G RDIMM sticks. The compatibility list only has a couple sticks listed on it which are very expensive, I don't assume there is a problem with getting memory not on the list as long as it fits the DDR3 1866 RDIMM requirement.

You pay a lot more for the faster memory and it doesn't make that much difference in performance because the slow part of the system is the drives.
I would suggest going with the 1600 LR DIMMs like these:

PS. Just because it says it is for a Dell server doesn't change what kind of memory it is.

Thanks for the suggestion, all listed models are 39.99 on amazon or newegg and are new not used. 4 dollars cheaper, new not used, and faster. Assuming no one knows the difference in the model numbers I guess I will just get the SL04 because it is the biggest number!

are new not used.

They are lying to you about that, but even if it is 'new' that doesn't make it better.

Good reasoning, but wrong. That number has to do with "Cas Latency" of the memory module.

Have you ever heard of NEMIX as a brand name? I have, and it is not a good one. They are NOT an acutal Supermicro approved vendor. The picture doesn't even have a Supermicro part tag. They are just claiming compatibility to try and boost their sales. So you are picking a no-name knockoff because it claims compatibility with Supermicro when you don't even have a Supermicro system... Your decision making process is flawed.

This is the kind of memory Supermicro uses:

This is a quality brand of memory:

Having been used previously does not make it less-good, in fact it makes it tested and known to be good.

Your repeated kind responses are always appreciated. The whole point of this thread was to ask about the memory. Quoting part of my response isn't really accurate. Like I said if no one can explain the labeling to me I have to just guess or assume that.... since you have still not explained it I have gained no useful knowledge on this subject. The only thing you did in your so characteristically friendly way is tell me the stuff I thought I was buying isn't real, so thank you for that I will indeed look at your items.

which of the 2 suggestions should I go for. I see the first one is slightly more and a little slower, but is local and would get it a month faster. You said the ram speed doesn't make that much of a difference, So your first suggestion would be not really noticeably different than the 2nd suggestion?

I don't like it. Those Xeon E5-2630L processors only run at 2 GHz which gives them a CPU Mark score of 8001 each:
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E5-2630L+@+2.00GHz&id=2222
That is very low, considering that they are 6 core processors. I think you could spend your money much more wisely.

I see another of your posts say you don't like the E5-2630L and to spend money in better areas, is that your same opinion with the E5-2630L V2?

https://www.cpubenchmark.net/high_end_cpus.html

I see they are charted at 9,088 passmark vs the 7,865 of the V1 that you didn't like. What is your favorite LGA 2011 Intel Xeon processor E5-1600* / 2600 / 4600 & v2 series.

EDIT:
I guess I should say my reasoning. As this board is dual CPU and WAYYY over kill for what I think I can make my freenas box do, I went for a low power CPU that seemed "fast" and affordable. I am new to freenas as you can see from my questions, the more I learn the more the server will end up doing, but I doubt I will ever get close to utilizing the power of even this low watt cpu.
