ADATA 8GB (2 x 4GB) XPG V2 DDR3 PC3-14900 1866Mhz Desktop Memory Model AX3U1866W4G10-DGV

Absolutely no problem with these. I originally started out with 8gb of RAM of this. It had no problem handling the work load, at least at the time, for what I did in the Army. I upgrade to 16gb of this, bought another set of 2 x 4gb, to give my pc the extra handling. I like to keep work loads on my hardware to a minimum, so I'm never seeing more than 50% usage of my RAM at any given time. Right now with this review and few other tabs (chrome), emails and school tabs (MS Edge), task manager, and Onenote... It's only using 30% of it's memory.All in all very good performance for even better price. It's quick on opening browers and applications once i've got it opened at least once. My motherboard only supports this RAM speed (1866MHz), but I've seen no loss in speed. The first set of RAM is 3 years old, and the second set of RAM is about a year old.
