My previous GeIL 1GB dual channel Kit died after a year of intense use. I have been shipped the following as a replacement: G.Skill 1GB DDR LA PC4800 (2x512MB) Dual Channel Kit I have never heard of G.Skill before but from what I have read, it should be on par with my previous GeIL PC4000 kit? I don't overclock anymore but I might be tempted to try again if this G.Skill stuff is up to it. I have an Athlon64 4000 Socket 939 CPU. Will this mean I can only choose between CAS 2 and 3, not 2.5? Also, while I'm here, can I just thank Overclockers for their exceptional friendly service, despite having a massive pile of RMA's to sort out!
