I have read that registered memory was a crutch to quicken the pace of technology (more capacity/channels) at the time for the cost of performance and power consumption. A dual channel kit (2x4GB) will work better and is more compatible than mixing single RAM modules. My work station circa 2011 takes ECC "E" (unbuffered at the time) and my server circa 2006 takes ECC "F" or fully buffered, which then for a time was labeled "R".

Delivering the keynote at the Institute of Electrical and Electronics Engineers International. You usually cannot mix them, but sometimes enterprise server boards can accept both with "R" usually allowing more installable memory capacity I think.įurther there was/is? a "U" which is unbuffered non-ECC.

They both are ECC, but they both are NOT registered. I'd like to buy an 8G SODIMM for my Acer Aspire One 725. To extrapolate, the "E" memory does not have the additional registers and is unbuffered.

Sometimes registered memory is called buffered memory. It allows you to take advantage of the ThinkStation full potential when working with 3D imaging, digital content creation, multimedia and other memory intensive. The PC3-12800 is non ECC, unbuffered and the PC3-12800U fits the same description.
The memory module I'm looking to acquire is a 1Rx4 PC3L-12800R-11-13-C2 8 gig module made by Hynix. unbuffered RAM) may be identified by an additional U in the designation.

As pointed out in the comments, the "R" memory is registered which "means it has additional buffers". My server is an Acer Altos T310 P3 server, and currently has a single 8GIG DIMM in it.
