Having problems with your Sony VAIO PCG-K25 Notebook ?

Change ram from 512 to 1 gig bios cannot read added ram

\015 The laptop came with 2 sticks of 256 PC2700i took those out and replaced them with 2 sticks of 512 PC3200BIOS shows RAM is 192MB and i can't edit the value.why is BIOS only seeing part of the RAM? BIOS is PhoenixBIOS version R0110X1is there an update for this BIOS? or is the problem something else?\015

Answers :

The original 2 sticks of 256 Mb of RAM gives you a total of 512
\015\012Mb of RAM. Two 512 Mb of RAM gives you a total of 1 Gb of RAM.
\015\012With two sticks of 512 Mb of RAM are you sure you got a total of 192 Mb of RAM, this is a lot less than the original RAM total of 512 Mb?
\015\012Should this be 1920 Mb of RAM?
\015\012If this 192 Mb is correct then the RAM modules are either not compatible with the laptop or if the RAM modules are not from the same manufacturer then they may not work together.
\015\012Most laptops have video cards that use part of the main RAM for video RAM, that is why the available RAM is less than the installed RAM modules. The amount of RAM the video card grabs depends upon the type of video card and in some cases the amount of video RAM can controlled in the BIOS setting.
I have the same problem. the laptop doesnt recognize all the OEM memory or all of the memory i put in to upgrade. sony does not offer bios upgrades on this model and if you flash the bios to a new version it doesnt help either.

Router problem. Time Warner had a internet problem last Sunday, April 26 here in the Northeast. They fixed it, but our internet still didn't function properly as it did before the TWC problem.

Netgear WGR614 v4. Only thing TWC said was to try and change channel. We tried but problem still exists.
