View Full Version : RAM voltage

10-03-2005, 05:31 AM
Hello iwas wondering if it matters if you use 2.5v or 2.8v RAM in a G4 MDD dual 1.25Ghz firewire 800 machine

Is there any difference between these specs for the afformentioned system?, concerning mainly the volts.

DDR PC3200 CL=3 UNBUFFERED NON-ECC DDR400 2.6V 64Meg x 64

DDR PC3200 2-2-2-6 UNBUFFERED NON-ECC DDR400 2.8V 64Meg x 64

thanks in advance

For some reason the MDD's are very very tempermental on the Ram. Off the shelf typically does not have the correct JDEC programming and will cause issues (crashing, non-start up.. etc).

Best bet is buy from a vendor who specifies the MDD's, ie HERE, Crucial, Kingston etc. each of these tests and programs for the specific model.

The Quicksilvers and Sawtooths were not as particular, as well the G5's seems to take a variety of speeds (and adjust accordingly).

Anyway, thats my take and experience with MDD's.

Can't stress enough the "Bad RAM" article from MacIntouch.
