Hello , I have VAIO PCG-Z1M , I wish to upgrade my slot memory ( now is 256 MB in slot + 256 on board ).
What is maximum of memory module in slot , user manual say 512 MB, but many dealers
say 1GB will work fine ! 1Gb will work or not,is it 512Mb really maximum or not ?
Thanks

Hi ivangara,

welcome to Club VAIO..

According to the Technical Specifications your Vaio’s Ram is upgradable to 1536 MB, use the following link to view:PCG-Z1M Technical Specifications

A large number of Club Vaio members have bought extra RAM from crucial.com an added benefit from buying from Crucial is their memory compatibility guarantee. To visit Crucial.com use this link: Crucial.com

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 ?
Best regards......

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 ?
