Just to clarify a few things that are incorrect:
1. Micron D9s do come in 128mb ICs, which is what is needed to make 2gb modules.
2. These ICs, D9 NHL, do not OC as well as their 64mb cousins, the GMH, GKX, etc.
3. We use ONLY Micron D9s in our 2gb XMS2 and DHX DDR2 modules at this time.
4. The RAMLIST linked here is often inaccurate.
