It is our mission to assure that the memory you ordered is compatible with your system. We only sell the models that are guaranteed to work on your computer.  Anything less - or less expensive - is a compatibility risk, and we'll tell you so.

FAQ before making the final selection:


Q: How much memory should I have?
A: For running today's computer software and operating systems, it's recommended to equip your computer with at least 512MB.

What you decide to do is entirely up to you, however whatever that might be, the result will be reflected in the time it takes to perform your task. Remember, the easier and less frustrating it is to do, the more successful you will be.

Q: Can I mix memory modules of different speeds, such as PC100 and PC133 sdram sodimm memory?
A: Yes, in all these cases. Sometimes it's cheaper to get the higher speed memory even if your computer does not support it, such as purchasing PC133 memory for a computer with a Front Side Bus speed of 100MHz (PC100 memory). The memory just won't run at the higher speed.

Q: Why are there SDRAM SODIMM price differences among memory modules that appear to have the exact same specifications and what are the differences between 256MB SDRAM SODIMM High Density and 256MB  SDRAM SODIMM Low Density memory chip?
A: 256MB PC133 High Density memory modules are less expensive and have only chips on one side of the card (single sided 8 chips memory). However a great many older systems in use today often cannot support the newer, higher density memory. Older memory controllers require
256MB PC133 Low Density memory - a memory module with twice as many chips because the chips used on that have a twice-lower density. 64MB and 128MB modules can be single sided however when it comes to 256MB module – the density becomes too high for the motherboard to support a single sided module.
