IBM laptop memory info

i have 2 ibm laptops that someone gave that i want to upgrade the memory

1 ibm 380z
2 ibm 600x

i was told by an online retailer that for ibm laptops i cannot use generic/compatible memory (which he had for sale) and must use ibm memory only (which he did not have available for sale so i was impressed with his honesty in not making a sale) so i bought ibm memory somewhere else for the 600x 256 now at 320mb ram but it was twice the price

so do i have to use ibm memory or can i use the generic/compatible memory

and if i add a 128 chip to the older 380z will that same chip fit the 600x which has room for one more chip

thank you

If you go to or you can search for your IBM model for compatibility. These are both high quality memory manufacturers (I just put a Kingston 512mb PC2700 stick into my Compaq X1360US) and they will tell you whether their memory is compatible in your system or not.

Crucial is one of the best deals if you order it online. You can get Kingston (Fry's Electronics, etc) or PNY memory (Compusa,etc) for less after rebate is they advertise the exact notebook memory type and size on sale after rebates. But that means you have to be patient.

For example, the Crucial PC2700 (333mhz) 512mb RAM module is abound $110 right now at Crucial (for most current notebooks sold in 2004) but Kingston is higher online. But I got it on sale at Fry's for $69 after rebate (on sale for a few days at a time or up to a week if in a Sunday newspaper ad).
