Need someone to explain to me laptop memory

[ahsia]

I have a Thinpad T20, and recently purchased memory from this site. Put it in, and it didn't work. This memory I bought are 16x16. I don't know exactly what that means. I called the company back, and he said I need 16x8 modules. But then there are 32x8? I am really confused. What do the numbers mean? And how do I know which ones to buy?

High density ram? I have a T20 and I think it uses the mobile BX chipest, BX doesn't support highdensity ram. I just bought a right module from crucial (selected Thinkpad T20 from their selector thing)

16x8 should be double-sided 128MB
16x16 should be single-sided 128MB

I could be wrong....

Yeah, that sounds right.

Basically it is the chip density, some mobos don't like high density RAM.

When they talk about 32Mx64, what does that 32M stand for, and what does that 64 stand for?

You should have clicked the Crucual.com link at the top-left of this page. They have a memory-selector that works by the exact laptop model.
