This memory worked out of the box. It got detected as 5200MHz in my motherboard that didn't list it in the QVL. I was able to choose speed of 5600MHz in the BIOS and it worked without any glitches. Very good stick of RAM at a good price.
Works in my Asus Z10pe-D15ws mobo. System stable - no issues with this RAM - runs at rated speed.
My Synology NAS 923+ is now 16 gigs smarter. Easy installation. I recommend this memory for your Synology equipment.
I bought these for my dual Xeon build. The memory came in well packaged. To my surprise, they also came with shiny metal heat sinks. I put them in and they just worked. Although long term quality is yet to be determined, I would recommend them for now.
Definitely an upgrade from the 10x 1gb sticks I had already!
