INFO: overclocking DDR2 memory list
 

I'm not sure about some modules, because I don't have some official proof for using Micron IC's, and I didn't tested all of them, so I matched these items (**), just to have in mind.
If somebody have doubts about other modules or have some information about other well overclocking modules, please let me know, so I can update this first post.

Important info on Micron chips:
The Stilt
"It seems that the 3.7ns chips are the best overclockers with tight latencies.
My Corsair 5400UL v1.2 sticks use MT47H64M8BT-37E (rev. A) chips and they are able to hit DDR960 speed with fairly tight 4-2-2-1 latencies. They can also take voltage up to 2.9V

My Corsair 8000UL sticks used MT47H64M8BT-3 (rev. A) chips, and they worked just fine at DDR800 3-2-2-1 with only 2.1V. Mushkin XP6400 seem to use the identical chips, but they can´t even post with 3-2-2-8 latencies with 2.3V (according to Legitreviews). So there is quite much difference between the steppings...

So:

Corsair TwinX kit 1GB 5400UL v1.2 = Micron "D9" MT47H64M8BT-37E (rev. A)"

"Wintec has also used those 3.7ns chips in their AmpX 5400 sticks. P/N: 39137183K-UA"

Elipda IC's based memory

Quote:
"While the benchmarking numbers were nearly identical the Elipda IC's that Mushkin uses are by far better overclockers at tight timings than any Micron Rev A IC's that we have seen."
