RAM Restriction

Hi friends
I have a acer laptop XP 64-bit installed on it .Currently I have 2GB RAM(i.e 2 1024MB sticks).I have only two RAM slots on my motherboard. Now I want to upgrade to 4GB since I want to install Vista-64bit Ultimate edition. Problem is that I checked at the acer website on my laptop manual it says laptop only supports 1024MB on single slot. My laptop can accept PC-4200, PC-5300 667 MHz DDR2 sticks. Just I want to know that if I'll installed 2GB single slot then what will happen or there is the chance of getting some what more memory.Any suggestions will be quite helpful.

Hi Floyd
See your as your laptop manufacturer website says it won't support more than 1GB on a single slot then it can't.If you'll go for more then either your computer won't start or it will recognize 1gb only from a single slot so better is do nothing because you already have maximum RAm according to your laptop.or buy another one.

The computer wont turn on at all.If the motherboard will detect more than its limit then it will not start. If it does start you will get a BSOD and crash.
