Pros: - Low profile. Clears my 2U heatsink, barely. :)
- Plug-n-Play into a Supermicro mobo running at 2133 Mhz out of the box.
Cons: Expensive: It was $550 when I bought it in 3rd quarter 2015.
Overall Review: Installed into an Supermicro MBD-X10SRA-F.
Pros: -Stable, hi-density, ECC server memory
-Put 8 of these in a an Asus X99-WS/IPMI motherboard for 128GB RAM without issue, running stable now for a month with ESX 6.0
-DDR4 speeds and performance
-Right now the only game in town if you want >65GB RAM in DDR4 on consumer boards with only 8 slots
-Made in China
Pros: Works on my Asus X99 WS N with Xeon E3 1650 v3.
Cons: Doesn't look to be overclockable.
Pros: Never gave me any trouble with my Asrock X99 WS-E + Intel Xeon E5-1650 v3 Haswell-EP 3.5GHz.
Tested in windows 10 and ubuntu 15.10 (both x64)
I use this with a massive noctua NHD-15 cooler with no space issues.
Cons: Expensive...hopefully you get what you pay for.
Pros: This is registered ECC server memory not unbuffered.
Cons: It does not state the type of ECC memory in the specifications. I ordered this memory assuming it was unbuffered since it did not say it was registered. I was wrong.
Overall Review: I'm sure it's good memory since it's from a good name in memory.
