Having problems with your Sony VAIO K45 Notebook ?

RAM problem Hi, Today I upgraded my RAM from 512MB to 1GB for Sony Vaio pcg-k45 and when I went to look at the my computer properties it still says 448MB of RAM. However, in the System Information it says I have 1GB of Memory. What's my next step?


Answers :

Hello, if you have an intel m processor for your sony then u are somewaht out of luck. the base memory is 256 megs and it is not in the motherboard but rather integrated in one of the slots itself, that means if u put a 512 mb chip into that certain slot it will only read 256. a lot of people are mislead into thinking they can put two 512s and get a gig of memory, but not true, at least not with most of the sony intel processors. find the base slot by switching chips around, then leave the 256mb chip there. then u can add a 512mb to the expandable slot and get over 700bytes. if u can find a 1gb compatible stick,then try that the same way, leave the original hynix base slot chip in and add the 1gb, if u can find one, then u will have a little over 1280 of which u can up the video graphic usage up to 128 in the bios, and have your 1gb in memory. if u find a 1gb memory chip that work,drop a line as to what brand and size u used
Hi,
\015\012There is no next step.
\015\012boot into the laptops bios setup. to see if the memory is registering as 1 gig or 500mb.
\015\012Also check if applicable, that both memory channels are enabled.
\015\012if you have Sony system information software installed try using that instead. Vaios do tend to have RAM slot issues. So the ram slot itself may be giving a false reading.
\015\012I,d remove the power and Battery. remove the newly installed Ram. And reseat it. pushing Inwards as well as downwards upon installation. Also check the Ram are a matched pair. Voltage and specifications on memory and Vaios are essential.
