Help me upgrade my confusing toshiba

[Uranium-235]

I used MMtools to look at the 1.60 and 2.00 bios and it shows a microcode for a T7300. I'm guessing anyways. oh well I spent $10/free shipping on ebay for a SLA45

One thing about this top is its listed under toshiba as having a max of 2gb of ram, well I have a 1gb and 2gb stick in it and it works fine. but it is having some trouble with the 2gb stick in alot A, windows won't boot, memtest fails to even try to start.

with the 2gb stick in slot b and 1gb in slot A, it works great, memtest runs fine. what do you guys think?

further research has come up with the GL960 as supporting 2GB and a 533max bus, and a 965G supporting 4gb /w a 667 bus

CPU-Z shows me to have a 965GM graphics but a GL960 chipset

I have 3 gigs, and cpu-z (and bios) show it to be in dual channel, and memtest shows up 3gb without errors

So I learned this is called "L shaped" dual channel. This can only mean that this is the 965 chipset (none of my research pointed to the GL960 being capable of this), which probably means it can take 4gb, but it can only take a 667 fsb chip. The 7300 is an 800fsb chip so I kinda screwed up there, did I?

here are the codes reported by mmtool (attachment)

I think 06fa is the T7300, the 661 is a celeron M

so the chipset can't take an 800fsb processor (can it? I know net burst could never take higher fsb chips and actually operate them-but these are core based chips)

can anyone tell me what those other supported chips are? anyone have experience with adding more cpu support to motherboards? this is a Toshiba but its AMI bios
