Can I use PC2-5300 in my laptop?

Specs: Windows XP
Hey all,

I want to upgrade the RAM on my laptop. The Acer website says that the computer can handle 2 GB of DDR-333 RAM. There is only 1 slot for RAM, and I cannot find a 2gb chip at 333. Would I be able to use a faster chip, just knowing it won't run at that speed because the bus speed will bottleneck? Or will the computer not even recognize RAM that much faster?

It uses ddr-sdram 333 pc2700. Everything I read says it supports 2 gigs of ram and has 2 slots. Are you sure it only has one?

yes it only has 1 slot. I cannot figure out why Acer says otherwise, but I have had the whole thing apart before...soldering a power jack, and there is definitely only 1 slot. I know that it uses 2 GB Max ddr-333 pc2700. But I cannot find any 2 gb that speed...I can only find it a lot faster than pc2700, I found PC5300 and was wondering if it'd work. Obviously the speed of the buss itself will be thelimiting factor, but with the RAM be recognized and work properly?

PC2700 is DDR. PC2-5300 is DDR2. They use different slots & cannot be interchanged. If you force the DDR2 SODIMM into the DDR SODIMM slot, you'll either fry the board, the RAM or both.

"yes it only has 1 slot"

No, there are 2. The 2nd one is underneath the 1st one.

Ahh, I see it now. Thanks for the info. I guess I never paid that much attention before, I was looking for two slots...not one stacked on the other, slightly offset. I don't know if I should do this or if I should start another thread...but I have an issue with the same computer in that when I right click on My Computer and go to properties, many times the processor speed will be screwed up. it is 1.8 GHz, but most of the time it'll say 792 MHz, ever once in a while it'll say 1.5 Ghz...and sometimes it is correct and says 1.8 GHz. Any ideas as to why this may be, and if it is slowing the machine down by only running at the 792 MHz, or is windows just yet again screwing with me?

"many times the processor speed will be screwed up"

There's nothing wrong. Either AMD's Cool 'n' Quiet or Intel's SpeedStep is enabled. These are power saving features that automatically vary the CPU speed based on load. If you were to disable it, your battery life between charges would take a nosedive.
