With 6400 Cell-Shock, just look if the kit hasn't got the "Vē" marking. If it's so then it's Micron D9GMH, or if you are lucky D9GKX.
As for something with D9, well Transcend AxeRam 1066+ and 1200+ are with Micron D9GMH only, and 6400 AxeRam with "N" letter behind the bar-code is also D9GMH.
Also Team Xtreem 9600 are with D9GKX only, but they are a bit expensive.
Old Team X. with silver heatspreaders are mostly D9GMH, just check the serial number. I have a kit of those 6400 and they o/c like sting.
