I have G.skill HZ's right now, but I am already going to RMA my second set (which only lasted a month

). G.skill offered to send me a different model this time, but im not sure if I should take them up on that offer or stay with the HZ's.
As far as I know, the HZ kit is one of the best overclocking DDR2 kits that G.skill makes (as well as the most expensive DDR2 2GB kit). Is this true, or do they sell other kits that overclock better? I dont really care if it is a 4gb kit or a 2gb kit, since I hardly use my full 2gb anyway.
I would just like to know this so I can decide whether or not to stick with the HZ's or ask for a different kit.
Any input appreciated.
