These are crazy fast sticks with Elpida Hyper MNH-E IC's. They clock like mad. Ran them at 1940 8-8-8-20 (6GB)on 1.65v on several x58 boards and 1880 8-8-8-20 (8GB) on a Crosshair IV 890FX. I've got 12GB sitting here, and I really only need 8GB since I moved to AMD for now. You cannot find these sticks anywhere, and before they sold out at Newegg, they were well over $200 per 4GB Kit. $169 OBO or trade for a WD Black HDD plus cash. As usual, there will be a small discount for crunchers and folders, and I will do a payment plan with well established members. I will ship international for actual shipping for members with good heatware.
