D9GSV and D9HNL chips have been confirmed on 2gb sticks
Very true that they make D9 2GB modules. People hear D9 and think of the D9GMH and D9GKX which were both doubled sided
1GB modules sold commonly in 2x1GB sets such as Crucial Ballistix and many many others. D9HNL is a more dense version and appears as single sided 1GB modules and double sided 2GB modules (2x2GB sets).
Your post just hit me as a little misleading in the wording. I just wanted to make sure it is clear to readers that the doubled sided 2GB modules are NOT the same D9 chips on the very overclockable 1GB modules we all knew and loved 1.5-3 years ago. Those 1GB modules were doubled sided D9GMH and GKX and are out of production as far as I know. Most current 1GB modules still using D9's now use the more dense D9HNL and GSV, the same ICs used in 2GB modules. However, since only 1GB is needed, they now come single sided.
So a single sided D9HNL has the same memory as a less dense but double sided D9GMH. So the problem of going from 1GB to 2GB modules wasn't as simple as lets just make them double sided as they were already double sided. They had to develop new, more dense IC's and kept the double sided concept, but switched to single sided 1GB modules using the same denser IC to cut costs by only manufacturing one type of IC instead of two.
And good post by the way, definitely a lot of confusion over AMD memory overclocking in these forums as not many people help out in the AMD memory section. Keep on educating Edited by durch - 7/1/09 at 1:40pm
