what means 1.28 Gb RAM?

[dorin]

hi guys,

i want to go from 512ram higher on my X40, but i;m tottaly confused.

i have only one slot where i can add the upgrading ram, but math is confusing:

512+512= 1024gb ram
512+1000= 1512gb ram

so why on my specs says maximum ram is 1.28?!?!?!

thanks,

dorin

For models with 256MB onboard memory, you can add a 1024GB module to max out at 1.28GB total. If you have 512MB onboard, then your max is really 1.5GB.

hi there,

theorethically you might be right but on x40 lenovo webpage http://www5.pc.ibm.com/uk/products.nsf/ ... ent#memory it is saying

Memory (RAM) std/max: 512MB / 1.28GB
RAM slots total: 1 SODIMM
RAM slots available: 1 SODIMM
RAM speed supported: 333MHz
RAM type: PC2700 DDR SDRAM

so...i do have integrated 512 then why its saying max is 1.28gb!?

thanks!

Some older models have only 256MB onboard, while the newer ones (including mine, 2371-9EU) have 512MB onboard. The 1.28GB stated on the IBM page is probably a typo.
