Pros: Works in my ASRock E3C226D2I ITX mobo. Kingston's site said it would, but the ASRock didn't show it on the compatibility list. Well, it works so I think the ASRock site just needs updated with 8GB DIMM support capability.

Cons: Besides the higher cost of ECC memory, none.

Pros: Installed in a Supermicro X10SL7-F-O uATX Server Motherboard for virtualization. Seems to be running well.

Cons: None

Pros: Setup a server running on a ASRock C2750D4I and this stuff runs just fine. Bought 4 of them and not a single dead stick. Running a ZFS file system across 28TB of physical drive space over samba, not a single hitch and I'm able to run my lightroom catalogue over my network and runs better than the external USB3 HDD I had storing my photos.

Cons: Nope none.

Overall Review: ECC is just so expensive...but it's protecting my data. Worth it.

Pros: Works, stable.

Cons: None

Overall Review: This RAM just works. ECC, very stable. I've been using Kingston RAM for years and never had a problem. This particular stick has been in a server running 24/7 for a month now. Not a hiccup the whole time.

Pros: Installed 2 of these memory on HP ProLiant M 310 Gen8 server. Excellent speed, ILO show message "not HP smart memory" but its green marked and works perfect.

Cons: None so far

Pros: Put 4 of these in a new Ivy Bridge build. Excellent speed and works perfectly.

Cons: None so far

Pros: - Lowest cost memory I could find for ProLiant - Accepted easily by my server during boot, no delays

Cons: - Higher cost compared to non-ECC RAM, however my motherboard rejects other non-ECC RAM and won't go through POST

Pros: Installation was basically plug and play, and system has worked without any crashes for over 7 weeks now. I love the security of ECC memory. System can run several days now without rebooting, whereas with non-ECC memory the system had to be rebooted daily if the work day was not to be interrupted with a crash and reboot. This memory is supposed to have automatic memory scrubbing, which could account for the computer's stability, but there is no way to tell if that is working.

Cons: I did have to turn off the Supermicro X10SAT's performance features to make the system stable. However, the motherboard only delivers about 1.49X volts to the memory, which requires 1.5 volts, and there is no way to change that.

Overall Review: I would recommend this memory to others, and I would definitely purchase it again. However, Kingston could make the product more interesting and salable if it offered access to papers on "Memory Scrubbing," "Memory Scrambling," and a definition of "T S" and why it is important. Kingston tech support will answer questions on these topics, but the best one can say about their answers is that they are laconic and terse.
