Good to know G.S Technician, thanks for posting that info! I had purchased a kit of this RAM from newegg's last batch (2/25) and they were GMH. I should admit that I was hoping for GKX but given the major price reduction I should have realized they wouldn't be GKX! In anycase the kit was very impressive and had the tightest default sub-timings I had ever seen on any kit of DDR2! With that said I ended up selling them because overall I wasn't very happy with them but still a great kit for the price, especially if they will start coming with GKX!
