Are there any compatibility issues due to density with sandy/ivy based xeons?

Specifically E5-2690 or E5-2650 v2?

Based on some motherboards I have the specifics state (Supermicro) you should be able to run 16x of these for 1TB of RAM.

IMHO these are more interesting\useful for 4-node and 8-node systems which limit RAM.
For instance in my 8-Node SuperMicro E5 v1\2 system you cuold run 256gb per-node for 2TB per-chassis.

This is still a premium price for 64GB DDR3 though considering 32GB LR DDR3 is 40-50$ for much faster RAM too.

I was under the impression Xeon e5 & E5v2 supported only 384/768G ram....

I wonder if anyone has tried higher?

In this particular case, you can only use 8 of these 64G LRDIMMS per CPU for a total of 512G per CPU.
***EDIT***
Actually, looking at the guide, it does show possible 12 LRDIMMs configuration for 768G total per CPU when using quad rank.

Ark is giving the 384/768 per cpu that I mentioned, although I wonder if the motherboard has it's own limitations...
I linked to ARK.

768GB per-CPU is 1.5TB per-motherboard with 24x dimms.

Unsure if you're pointing out CPU or motherboard limitations, but obviously you must take both into account when building ;) as there's no 128GB DDR3 AFAIK.

So 512 is the limit for most boards with 16 slots, but that's still per-CPU. So 1TB is possible with 16x 64GB as long as you don't run out of ranks.

I think we're saying the same thing :D

They do make 4R 64GB LR and that's what you need to max it all out :) if that was your goal, but yeah, 8R 64GB will be cheaper and limiting.


Example: HYNIX HMTA8GL7MHR4C

Yeah I think we are as well....I have a 1 cpu desktop & 2 , dual socket servers (v1 cpus), and I don't think I can drop 8 of these for a single CPU (even if it was quad rank) due to limitations of 384G ram on Xeon E5-v1

I didn't check E5 V1 CPU only the V2 I'm using :D Sorry, unsure of V1.
