Hello,
My aspire notebook (exact model no. is: 5745G-644G50MNKS) has Samsung 2x2GB DDR3 1333MHz CL9, Hitachi 500GB 5400RPM SATA II HDD & Mat**bleep**a DVD Ram Drive.
I want to upgrade my RAM to 8GB, HDD to 7200RPM 1TB drive or 512GB SSD and DVD RAM to the Blu Ray ROM drive.
First at all, I want to know about the available ram slots information, maximum memory capacity and speed supported, sata version of my existing mechanical HDD and max possible capacity, compatible blu ray roms for my model.
The official specs data sheet was gone a long ago from acer.com and I'm unable to find any technical information about my model in 3rd party sites. So, please somebody can help me with the compatibility of the above upgrades?
Thanks before!
*** EDIT ***
I've found the following details from a blog. But some parts ain't matched with my notebook. Also that model number is also different from mine(Mine has "G" at the end). BTW As I remember, this is the original specs page was in acer.com before and may be I'm using the same product family. There are little variations But I still can trust these info. Special kudos for whoever copied this info and republished it in his own blog.
