    Would need to know the specific model number. It should be something like Optiplex 160 or GX240.

Best and easiest thing to do is go to and run a scan of your computer. It will tell you what you have, how much it will hold, and what kind of modules.

Yes, it's safe.

This laptop came with 128mb ram, you can safely install 2 sticks of 256mb for a maximum of 512mb with no bios update.
You need pc100 sodimms.
Amazon or ebay will be the best bet as this memory is expensive now from a retailer.
I found 256mb sticks for under $10 buy it now on ebay

Why does a 1GB DDR PC2700 333MHz RAM show as 32Mb in a Dell Optiplex GX260.I want to upgrade from the existing 256Mb and hopefully run the two RAM together

It is because this computer only supports 200 or 266 MHZ SDRAM modules. The one that you are trying to install is not compatible.

Windows XP won't boot with "CREATIVE SOLUTIONS" PC

That machine is too underpowared to run xp pro.
Windows XP Media Center Edition
1.6 GHz CPU, 256MB Ram, and DirectX 9 hardware-accelerated GPU
you may get it to run but it is going to be dead slow. you will be waiting forever to load any apps with a processor under a gig, and less than 512 mhz of memory, it may work for emulation, but that's even questionable. I don't want to aggrvate you but that config is a decade old. Vista for instance needs at least 2 gigs of ram and a dualcore to run right. sorry bud, if you are dead set on it, the only thing you coula do is juice up the memory, to whatever the board is rated to take, or I would run windows 98, peace

OptiPlex GX270 mini tower

Remove the 256mb memory and insert the 512mb memory in slot1 and see whether it works. Please note that the memory needs to be in pairs.

I think the GX260 is mini tower has two different moles
1) PC3200 compatible with memory - 184 Pin DDR3200 400MHz

2) PC2700 compatible with memory -184 Pin DDR2700 333MHz

Please enter the service tag on and find the manual and the right memory for your PC

All the best!

I have a compaq with a 90 gig hard drive, at presenr I am running 384 bytes of RAM. How much will this PC safely handle?

Depends! The amount of RAM has nothing to do with capacity of the hard drive. If your motherboard is a P3, it probably has to memory slots that will handle 256mb each (512 total). It sounds like you have a 128mm chip and a 256mb chip installed now. I won't even attempt to run XP with less than 256mb of RAM. You can run XP with 128mb, but not very well. With Windows XP SP2, you will have to have at least 256MB. Most P4 or newer computers use DDR RAM wich can be bought at larger capacity (ie 1000MB).
