    5.0 out of 5 stars Great, works well with Alienware Area-51 R2 with a small workaround
    Reviewed in the United States on January 11, 2017
    Size: 64GB Kit (16GBx4) DR
    I bought this product elsewhere to use with my Alienware Area-51 R2.

    Despite Dell official spec indicating 32GB is the max, 64GB will work, yes and no.

    Initially computer froze when the login screen came up. I did Google search around this issue and found that Alienware Command Center not being compatible with 64GB ram, causing it to crash.

    Workaround is to stop a service called MSICPU_CC - I strongly recommend to do this step before installing the memory.

    Otherwise it is a great product and my Area-51 is now blazing fast!

    I purchased 4 more of these the other week for an old X99 Sabertooth and just installed them 5 days ago. They were recognized immediately in the bios and Win10 on their first power-up and passed being stressed.
    This is the final RAM upgrade for this mobo that was purchased in '14, with it now having all channels filled. I have been running these Crucial 4GB sticks the entire time, with no issues. Although I run a decent overclock on the CPU, I leave the RAM at stock speeds as the gains aren't seemingly worth the watts/heat. I have gotten these to 20% over stock but the controller became warm (even with more-than-proper airflow), and overall temps went up 2 degrees cel. The sticks did not glitch for me until about 25% over, but at 20% they were stable.
