According to this Supermicro X9 memory configuration guide, it should be ok to have up to 2 of these per channel, max of 8 per cpu. However, speed will drop to 1066 when more than 1 per channel is used.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.Are there any compatibility issues due to density with sandy/ivy based xeons?

I was under the impression Xeon e5 & E5v2 supported only 384/768G ram....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.
512GB per-CPU with LRDIMMI was under the impression Xeon e5 & E5v2 supported only 384/768G ram....
I wonder if anyone has tried higher?
Ark is giving the 384/768 per cpu that I mentioned, although I wonder if the motherboard has it's own limitations...512GB per-CPU
In this particular case, you can only use 8 of these 64G LRDIMMS per CPU for a total of 512G per CPU.I was under the impression Xeon e5 & E5v2 supported only 384/768G ram....

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.In this particular case, you can only use 8 of these 64G LRDIMMS per CPU for a total of 512G per CPU.
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-v1I 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
