Can i Upgrade my ram to 6-8GB on my Acer Aspire 6920G?

Hey there i currently have an Acer Aspire 6920G with Windows 7 Ultimate 32-Bit and 3GB ram. I am aware that 32-bit operating systems can only detect up to 4GB ram which is not good enough for myself.i was wondering if i upgraded my computer to a 64-bit OS (Windows 7 Ultimate 64-bit) that i would be able to upgrade my ram to a little higher because besides the OS my laptop itself is a DDR2 Ram slot at 200 pins and i dont know the amount of ram you can go up to with them is limited to 4 or what, not to forget my computer only has 2 slots to include ram. also to mention i went to RAM Memory Upgrade: Dell, Mac, Apple, HP, Compaq. USB drives, SSD at Crucial.com/uk and i entered my computer model and it said that my computers "maximum memory" could only exceed to about 4GB ram and i dont know if this is because the online scanner can tell that my acer model 6920G is a 32-bit or because of the ram slots or what but i would REALLY appriciate if if someone could tell me if possible for me to at least get a little more than 4GB , maybe 6 (2+4) or 8(4+4) or if anyone has had this done? thanks

 

You need a 64bit OS to see and use over 4GB RAM (6 or 8GB)... however, in order for your system to do that, your BIOS and chipset must support such quantities of memory.

What is your chipset and controller?
You can find that information out via CPU-Z.

The Aspire 6920G if I'm not mistaken comes with Mobile Intel PM965 Express Chipset.
Per Intel's website, that chipset supports up to 4GB RAM... however, I think there were cases with people who upgraded to 8GB as well.
Also, another poster called Andy stated that the chipset does support 8GB.

Theoretically, you could buy the 2x4GB RAM sticks and try them out (provided you can return them and get your money back in case it doesn't work).

Bottom line is, you won't know until you try.
Intel themselves have managed to mess up certain information regarding what their chipset supports or not, and laptop manufacturers aren't nuts to engage in such a discussion because their priority is to convince you to buy a new laptop instead of upgrading (hence they will often claim various upgrades are 'impossible' - and Intel is no better in certain situations, but for the most pair, the info posted on their website is genuine - still, I prefer taking it with a grain of salt regardless).

Btw... the RAM on your chipset will probably have a max. operational frequency of 667Mhz... so even an 800Mhz type will downclock to the max. supported speed (the point of my mentioning this in the first place is to get whichever is cheaper - as RAM speeds don't impact performance in any noticeable way).

Oh and, if you want, you could look into getting the ram off ebay.
It might be cheaper than buying it from that Corsair official website (just make sure the ebay seller is genuine).

 

AFA<!-- -->IK there exist no 4GB DDR2 SO-DIMM modules. IIRC the JEDEC DDR2 specification only allows unbuffered modules in sizes 256MB, 512MB, 1024MB and 2048MB. Any other size is a proprietary extension to DDR2.

 

Are you serious?
4GB DRR2 SO-DIMM modules exist.
They are a bit pricey, but they do exist.
I'm waiting for 2x4GB DDR2 So-Dimm 800Mhz sticks to arrive for my laptop.
;-)

 

I'm pretty sure those are either non-standard modules designed for one particular laptop, or buffered/ECC modules for SFF servers. 2GB is the largest size JEDEC standards allow for an unbuffered DDR2 SO-DIMM.

 

Has anyone tried plugging in two 4 GB DDR2 RAM modules into the Acer Aspire 6920G laptop and can share the results?
I don't want to buy two DDR2 RAM modules as it's quite expensive these days before I'm not completely sure that it'll work.
