If I draw the right conclusions then it is safe to say the only benefit of the 5,8 over the 5,6 Powerbook is the 128MB VRAM and the high res screen. But speedwise both are *really* on par (except for applicatons requiring more than 64MB VRAM).
Question is whether the higehr screen resolution is really a benefit. Pixels must be pretty small I guess.

@Zylesea

Unless you're lucky enough to get one of the 5,6 128MB VRam variants (me pats Powerbook).

boot_wb: you're a lucky man

I've just tried putting in some 1GB PC2-5300s-555 ddr 667 memory into a Powerbook HD, and it dosn't seem to work in both my 15" and 17", Anyone had any luck with the slighty higher speed in the Powerbooks?

With both in it Beeps once, with only one in it chimes then beeps 3 times for bad ram, the memory was working well in another PC

I meant they should work..

The DDR2-4200s-444 work fine in both.

Tested the memory as fine in my work W*ndows PC, so it's not bad memory, Well, anyway I just cracked and bought 2 1GB HYNIX 2Rx8 PC2-4200S-444-12 DDR2 sticks, hopefully that the Powerbooks will be less choosy about those.

They pc2-4200 memory turned up and working fine, maybe there is a problem with PC-5300, dunno, buyer beware and all that..

Oh, BTW My Quad G5 does the same with faster memory, works but is reported as being slower, not ever being the maximum speed that the MB can take.

There was web page on the cruical web site where they say that the memory that they supply is fine and it's System Profiler is wrong, all the faster memory is running at the top speed that the motherboard runs at.

If I get time I'll dig it out, but re: memory speed, I wouldn't worry about it.

Bump!
