    I was concerned at 1st as the shipping date was saying up to 2 months ahead of the purchase date...however after conferring with the seller she reassured me they usually deliver in around 12 days which sounded reasonable and was satisfactory. The Ram were well packaged, in Top condition and I am happy with the performance and service I received. Many Thanks =)

    BUY IT!!!!!!!

    Didn't know my Hp pavilion coulden't run at full speeds with other memory with XMP. This doesn't need a motherboad with XMP to run at full speeds which is great. Still awesome without a heatspreader!
