So I was proven wrong by Claude, and thankfully so, because thanks to his discovery, I went out and bought 4GB of RAM (2x2GB DDR2 667 5ms latency), it also just happened to be Kingston. Came home booted it up, and ofc, only 3GB available (because its a 32Bit OS). So I thought what the heck, I’ll install Win7 64Bit RTM (Because I got this from MSDN). Everything I need worked fine. I don’t use the built in web cam much, so I haven’t installed a driver for that, but the rest of the Sony works perfectly. I found a graphics driver on www.laptopvideo2go.com. Awesome stuff…
Huge thanks to Claude, who has pointed something out. Although Sony tell you, its impossible, it is possible to add 4GB’s of RAM. I did a system scan using this excellent utility, and as it turns out, the real chipset is Intel PM965 Revision C0. I then found the Intel tech specs for that chipset here (point 1.1.2) Notice this time 4GB. Claude has already upgraded to 4GBs. So now I know what I’m doing next pay day – buying more ram.
Thanks again Claude for clearing this up!
For those of you still interested, here is the original post:
I decided I would create this post for those of you who own this model notebook (Sony Vaio VGN-AR41S) and are wondering whats the deal with upgrading the RAM.
After hours of searching the web, I have the answer, unfortunately its a bit of a low blow. If it makes you feel any better, I own one too, and I am equally dissapointed.
You’re not going to get more RAM in there because of the chip set – Mobile Intel GL960 Express Chipset. You can read the full specs here or I will save you the time, and here is a screen shot of the interesting bit.
So yeah sorry to be the one who has to bring you this bad news, it seems the VGN-AR41S will die alongside the rest of 32Bit computing. I would not recommended upgrading the motherboard either, because along with this you’re no doubt going to end up having to upgrade / replace the graphics card. Not to mention, I doubt very much you’re just going to find a compatible laptop for sale.
I’ve decided that after this notebook finally kicks in I will buy a desktop computer and in the future only have a Netbook for portability. Desktops are a more long term answer to computing. They’re generally much cheaper, and when they get older can easily be upgraded.
