Somewhere in a thread I've read about this myth (hint) with ram-upgrade for a D600 and so on, it should be better with DDR2700 modules instead of DDR2100...Rubbish, bullsh@t
No way!
I've tried with DDR2700, and?! Nothing!!! Bios still says XXXMB@266MHz
not @333Mz...The only thing is, according to Everest tool - ram timings, 2-3-3-6 2ns instead of 2,5-3-3-6 2,5ns
And system still runs with 133/266MHz 
Anyway...
