Pros: Value, factory clocks, CAS 9
Cons: Limited OC ability
This RAM is binned 1600mhz RAM of the same flavor, but factory OC'd and tested to 1866 on stock clocks. I bought mine on a Newegg blowout special, so the price to performance is good. I would recommend this RAM, but if you are folding, try and find a good 2133mhz kit when they go on sale.
