i just upgraded my 17 1.3ghz PB from (2) 512 chips to (1) 512 and (1) new 1 gig chip. i was surprised to see that Xbench is registering SLOWER memory tests and slower overall results than before the upgrade. but i don't think its a bad chip. just the 1 gig chip by itself registers as fast as the (2) 512's did. but any combo of 1.5 gigs registers slower. is this a fault of Xbench or???
any other apps i can test RAM speeds with, or???
any advice appreciated, thanks!
