TWINX XMS4000PT question

[skinlab]

just got a gig of these, but i have a question if anyone could possibly answer it rev.1 of this memory had 4ns ram (whether black or platinum heatspreaders), the ones i got are rev.2.1, do they still carry the same chips? if so, what changes were made to warrant a change in revision number? if not, what kind of chips were used in rev. 2.1? thanks.

Hynix IC's rate their IC's by speed, so a D43 would be 433 Mhz and D5 would be 500 Mhz. We are currantly use Sansung Rev F -5 with this module Rev 2.1, and Hynix D5 Rev C for XMS4400.
