|I've been trying to upgrade the RAM in my Toshiba Satellite l100 Pro laptop. I have two sticks of 1GB DDR2 PC2-5300 SODIMM memory, and when I put both of them in at once, my laptop refuses to boot up. Sometimes it powers up but does nothing; sometimes it bleeps; sometimes it even gets halfway to booting into Windows (XP) before I get a "Page Fault in NonPaged Area" BSOD. |
What puzzles me is that if I boot up with just a single ram stick, it runs fine. It boots up with either stick, so it's not the ram chips themselves. It boots up regardless of what slot the chip is in, so it's not the slots. And it boots up fine if I put two 512mb chips in (512 pc-4200), so it's not some problem with using both channels at once.
So what is it? The only thing I can think of is some kind of voltage issue; maybe there's not enough power for two 1gb chips. But the BIOS won't let me change voltages (it doesn't even list them), I can't seem to see any jumpers on the motherboard (although I've not taken the laptop apart completely yet), and according to programs like HWINFO, the 1gb chip is 1.8v, just like the 512s. So I'm stumped. Any suggestions?
