Hi Thalamus , thanks for friendly welcome
I was follow that link for PCG-Z1M Technical Specifications , but there they say only 768 MB (fixed 256 + 512 slot ) 😞
What do you think ,can I buy 1GB module SO-DIMM DDR1,and will then I have 1280 MB ?

Hi ivangara,

I wouldn't recommend a 1GB module but if you want to try it then that's up to you..

Hi,thanks but..why you wouldn't recommend a 1GB module ?

Please ,anybody know is it 512MB module really maximum or not ? Can I use 1GB memory module or not ?

Hi ivangara,

I don't think that your Vaio will not recognize a 1GB module and therefore may not boot correctly..

But as I said if you wish to try then that's your choice, RAM's quite cheap at the moment..

OK Thalamus ,thanks so much ......
Just last question, my old memory is 256MB CL2 , can I use CL2,5 ?
What is default for my Z1M .... CL2 or CL2,5 ?
