How much ram can my Laptop handle?

I wondr how much i can have in my laptop is therea way of checking cant seem to find the answer anyway.

 

Download and run CPU-Z and see if you can get the chipset that you have. The 910 chipset can only handle 2GB of RAM I believe, whereas the 915 can hold 4GB if the manufacturer BIOS support it.

 

is it this laptop that u have? http://www.nec-computers.com.my/Products/Product_Specs.asp?CID=4&RangeID=6&CatID=12&ModID=270


if it is then it should be 3GB of ram 'cos it has the Intel® 945PM Chipset.
u can install 2x2GB of ram in it and it should boot but it won't see the entire 4th GB; you'll only end up with around 3.2GB~ or there abouts.

 

Yer thats my laptop so that means if i take 512 out and add a 2 gb so i have 3 it willl work fine?

 

yeah. should work. i have a dv9008tx laptop here that uses the i945pm chipset and i am currently running 3GB of ram in 1x1GB + 1x2GB configuration.

 

i have read both that the 945pm/gm chipset can show all 4gb of memory (in 64bit windows) and also that it only shows 3gb even in a 64bit windows

can anyone confirm that it can hold 4gb?

i have the dv2500t and running 4gb of memory and can see it all in 64bit windows. HP sais it won't allow it but the chipset allows it so it works. the 945pm/gm also allows 4gb but peope still say there seomthign wrong with it

any info will always help

 

could u tell me where u've read it? i have not seen even 1 post where someone is able to see 4GB of ram with their laptop that uses a i945 chipset.

 

I'll confirm it. I was looking to upgrade and went through Intel's whitepaper for the 945PM chipset. It will support 4GB of installed memory, but you will not be able to address all of it from Windows. You'll see from between 3.2-3.8GB total memory, depends on your BIOS and what hardware you have installed.

 

Those whitepapers may have been written before any 64-bit OS's were finalized.. could be that 4gb works fine with a new enough bios (older bioses may limit) and a 64-bit OS.

edit

This post describes the i945 chipsets limits well.

if i was a hardware designer and i was asked to write that paper i wouldn't even factor in how many number of bits the OS is. some of you really like to come up with ridiculous reasons.
i'm glad Pitabred found out that it is in fact a hardware limitation and no amount of BIOS update will allow it to see 4GB. From the very beginning i was told (read from threads) that its a limitation of the controller, but didn't have prove of it.

 

whitepapers usually always have outdated information since they come out months before the technology is even officially released. They are available to the public only afterwards in most cases though.
