People do that with all laptops to squeeze the most battery life out of them, and to lessen the need for the fan to be used so much.

Fujitsu ship nearly all their M3438G's with 533MHz DDR2 Ram, unless asked for 400MHz by retailers. That's not Fujitsu's fault, but your retailer.
However, you can buy 533MHz DDR Ram sticks and easily swap them out. The RAM is very user accessible in the M3438G.
However, I took the issue up with LaptopsDirect (the retailer I bought the laptop from), as they claimed that 533MHz DDR2 Ram was pre-installed, which it wasn't (they included 400MHz DDR2). I eventually got them to exchange the 400MHz DDR2 for 533MHz DDR2 sticks....
...I then benchmarked the results comparing between the two setups (2 x 512MB DDR2 400MHz against 2 x 512MB DDR2 533MHz) and in fact the 400MHz sticks came out as being just a miniscule amount faster than the 533MHz.
I presumed that a 533MHz stick of RAM would be more suited to a CPU with 533MHz FSB, but this isn't the case.

As for 1 x 1Gb DDR2 RAM not being as effective as 2 x 512MB DDR2, this is, as far as I know, to do with DDR2 RAM itself, and certainly NOT limited to Fujitsu, but all computers which use DDR2 RAM. As I understand it, for maximum efficiency when using DDR2 RAM you need both (dual) channels accessing the same amount of memory in order to see any benefits.
|and the 6800go without a fan, which people underclock.
By "people" I think you might be referring to, err, just me.
To put it into perspective, I'm NOT a gamer. - I bought this computer for its strengths as a very capable 'music production' tool and hence have no need for such a nice graphics card - and thus I seeked to throttle back or deactivate any frills on the laptop I didn't use nor need. For my particular intended use, one of these 'frills' included the graphics card.
|either dell people are brilliant or very stupid, as they made 6 air-intakes, 2 permanent fans (one 4 cpu, one 4 gpu).
so, they should have put 2 fans and more air-intakes. what a shame,
I presume Fujitsu went for a larger single fan, than two small ones. If so: 1) This would shift the same volume of air, and 2) would be actually quieter than two little fans whining all the time.
It must work well as I can hardly hear the laptop. Only a very light hussssh in the background. Sometimes I have to get my ear right down to the laptop to hear it.
|I'm not even talking about the new problems of those IRQs. any producer might have them.
Can you explain more about this?
I admit, the user accessibility of the BIOS is utterly dreadful. You can't tweak anything, it's all locked and hidden away. Grrr.
