Additionally, it is backed by a lifetime warranty for added peace of mind.

Didn't work from the first try. Had to reinsert with more force. But after that worked great, paired with old stick and did not get any problems

I wasn't expecting miracles to begin with. I just needed extra ram to accommodate a specific program. In that capacity the product worked perfectly. And it has improved load times and performance in general. And at a good price too.

Really Punctual Delivery

Did my research before purchasing to make sure that the RAM would work on my motherboard. Made the purchase and the RAM arrived within 2 days which was fantastic. I have them for two weeks now and no issues so far. RAM installed fine and are operating as advertised (2400Mhz). 32 GB and loads of room to run all my applications. Definitely will buy off this company again. I bought 2 DIMMs.

The Ram arrived promptly, and well packaged and fitted easily into the second slot exactly as required. The specs meant the new ram functioned perfectly with the existing ram and helped improve the performance of my PC. A good improvement for a small investment !

These strips were installed onto an Asus X99 Deluxe with an Intel i7 2011v3 6 cores. Absolutely no problem with performance.
