Question
Windows XP boots with 1x2GB ram, but with 2x2GB ram, won't start on Toshiba Satellite A200-MR1
Recently purchased a new Toshiba Satellite A200-MR108C laptop here in Canada.
Vista came installed, downgraded to WinXP SP3.
Stock laptop came with 2x512 MB ram.
I purchased 2x 2GB ram to upgrade to 4GB ram. Before doing so, I made sure that my motherboard was indeed compatible and expandable to 4GB ram.
I've gotten Windows XP installed fine, everything works using the 2x512MB ram. When I change them to the 2x2GB ram, the computer will start up, loading bar will complete, windows starts for 1 second (desktop and mouse pointer appear) then suddenly crashes into a checkered blue/black screen of mess.
A few points:
1. I am sure both 2GB are non-defective.
2. WinXP works and boots up fine when I only insert 1x2GB into the machine. When I insert both is when it does not boot. I have tested both ram using this method, both work fine when they are the only chips inserted.
3. I am aware that my XP is 32-bit and I won't get the full potential of 4GB without 64-bit XP, and I am fine with the 3.0/3.5GB of ram or whatever it is.
4. They are identical chips, Kingston brand, same MHZ as the stock ram, and I'm almost definitely sure they're compatible. Like I said earlier, the machine boots just fine when there's 1x2GB in the machine.
5. When I start up the computer WITH 2x2GB in the machine, if I enter the BIOS, all 4GB are detected. The bios installed is Phoenix, v. 5.6 if I remember correctly. The BIOS seems extremely limited, as there are no options I can change or adjust, more of an informative display setup and nothing else. BIOS is entered by pressing F2 at the start up.
Any help would be appreciated. Thanks for your time.

Sorry my bad enlgish :) I try again... http://www.microsoft.com/w
The second vista and bios: Try install vista.
If that work, u sure, u have sofware problem (with windows Xp) and not hardware.
yes edit the boot.ini file, take off read only. open in notepad. it is located in the root of C: or what ever drive xp is installed in. this allows 3 gig for user applications and reserves the last gig for windows kernel mode components.
at the end of the windows line add /3GB save, make read only and boot up.
you can also try /PAE instead of /3GB or combine them.
the /3GB switch from my understanding is it basically divides the ram it sees into 2 manageable chunks. it sees a 3 gig chunk and a 1 gig chunk. 32 bit cannot address full 4 gigs unless written to handle it. apparently some linux distros can.
also check and see if there is any chipset settings in bios. or any memory settings. there might be a memory remapping setting you can turn on that should allow you to boot up.
run with the system below 4 gig ram configuration.
disable all extra software at startup. you can do that in the run keys in registry, put a rem in front of them.
disable any unnecessary services and ones that you can turn off.
then reboot the system with 4 gig. i did some research and some have reported programs causing conflicts, specifically additional software with graphics cards.
everest, they got a free demo

oh god. okay, so it's a Intel Crestline-GML GL960. From google results, some people are reporting that it's a 2GB max. Can anyone confirm this with an official source?
That being said, and with the specs above, this is a very important question.
Had this laptop been upgradeable to 4GB of ram, how much of a performance boost would it have gotten? Significant or not? Taking into mind I'd be using it on a 32-bit Windows XP. The other specs of the laptop, as seen above aren't the greatest, so would those be more of a performance limitation than the ram?
If you use just office applications i think u not loose to much. 2GB more than enough to xp :) But the bad news: Just 2GB max in specs. http://www.intel.com/Asset
I guess the general idea with RAM is that "more is better", but the significance of 3+ GB as compared with 2 GB may not be great. It's also a power factor, albeit not a big one; your battery will drain faster with more RAM. Unless you do some terribly heavy multitasking, I doubt you'd see much of a performance gain going from 2 to 3 G.

From reading other resources on the net, it appears to be an issue with the BIOS. I'm not 100% sure though. My current BIOS is the most updated one available from toshiba.ca. Other users have stated that they are re-flashing with other BIOS for the same chipset, but at that point, I don't even know where to start or what to do.
