Crucial 8GB Single DDR3/DDR3L 1600 MT/s (PC3-12800) DR x8 ECC UDIMM 240-Pin Memory - CT102472BD160B

Perfect for my FreeNAS build. This is server ECC memory which makes it quite a bit more expensive than standard desktop memory. If you have a server grade motherboard and are planning on building a NAS, you really should go for ECC memory. Otherwise you are seriously putting your data at risk. There are plenty of articles on Google that will explain why this is true. I was not a believer at first, but I'm glad I spent the extra money.The motherboard that I used this memory in is the ASRock C2750D4I Mini ITX. I'm not sure how much of this I can attribute to this memory, but my system has worked flawlessly for me. I even use it for real-time transcoding with Plex and it doesn't skip a beat, even with 2-3 HD streams.Check the compatibility list for your MB before buying this. Crucial also has a nice compatibility lookup tool on their website.

It seems to do very well in my server-of-all-work, based on the Supermicro A1SRM-2558F motherboard running FreeBSD 10.2 with a 3-way ZFS mirror for the served files/data. I chose ZFS for its anti-bitrot feature because I was being driven mad by TBs of backups in various stages of decay.The Atom cp on the board proved surprisingly powerful (running scrub, it verifies the goodness of the current 3 x ~250GB of data in about 45 minutes), so I decided to make the box not just a fileserver, but the LAN's nameserver (nsd), and my local toy FAMP server (FreeBSD 10.2, Apache 2.4, MariaDB 10.1, and PHP 7.0) as well. Since for convenience I also installed XFCE4 over X11, the total puts a real dent in the original 16GB, top tells me, so I've just ordered another 16 to give it some breathing room.

RAM have much errors by memtest. I tested it in 2 servers with ECC support UDIMM, but the same result. Server freeze after few minutes. Its not economic to return it to US.

Based upon the fantastic experiences with compatibility and performance that I've had over the past decade with Crucial memory, selection of these kits was a no-brainer. Installation was trouble-free, and the server detected all memory without issue. Extensive execution of diagnostic tests came back clean, and I now have ample headroom to spin up as many VMs as I could possibly need in a home/lab environment. Amazon's price cannot be beat, and shipping was quick as always. With the continued longevity of computer systems in today's environment, spending the extra money on quality memory will be critical in ensuring trouble-free operation. Due to the upcoming dominance of DDR4 for next-generation desktop and server platforms, you'd be wise to stock up on DDR3 while it's still reasonably priced.

The memory I purchased did work fine but got issues with this reseller "antonline " they send me one stick of RAM and took another two weeks to send me the other one without even notifying they are going to send the second as they were not aware of having another stick, told me they were investigating the matter.I got to buy from another reseller after Amazon rep. advisement that did work great and I got my package in 3 business days. As anybody going to purchase this memory, it's special ECC memory with law voltage 1.3V that fits mainly server or desktop Xeon CPU.

I was gifted an unused ASUS M5A 88V EVO (bios 1801) from a friend who had issues getting memory to work with it.I decided to build a FreeNAS array because the mobo supports ECC memory. This was the third set of memory I tried (previously other brands) and the first one that worked. The box is running great with zraid2 (6 disks) for one month now. First ran Memtest for over 24 hours and did not find any faults using default bios settings apart from ECC mode: Super (DRAM Scrub every 8 hours).dmidecode reports:Speed: 1600 MHz, Type Detail: Synchronous, Total Width: 72 bits, Error Correction Type: Single-bit ECC.Very happy to get good use of old mobo.

It's RAM. What else is there to say? Well if you're looking for RAM to fit a ReadyNas 516 I'm here to tell you that it works flawlessly. There are two slots and one is already populated with a 4GB DIMM. So if you want 8GB you just need to add 1 4GB DIMM (like this one). Installation can be a bit tricky so google for instructions before trying and be sure to have an external backup before you start and to run the RAM tests before you commit to using the ReadyNAS after the upgrade.

The ASROCK motherboard (and it's replacement ) I purchased to work with this RAM were not stable. I had to send them back, then had no use for the RAM, so had to ship it back too.
