Upgraded RAM, recognised by BIOS, nothing else works

Hi guys,

I'm sorry if this question is mundane or has been answered to death, but I really did try finding an answer through Google and didn't really get anywhere. Here's my situation:

I have a 1.5-year-old Sony VAIO VPCF13E8E with 4GB RAM, 2x DDR3 2GB 532Mhz, and am running Windows 7 64-bit. I'm attaching a Speccy .txt with other details as well. Today I bought an 8GB stick of Corsair RAM, cmso8gx3m1a1333c9, (http://www.corsair.com/memory/laptop-memory-upgrades/va...). It fit in, the BIOS recognised it and started to boot Windows. It stuck on the "Starting Windows" screen, safe boot got stuck on classpnp.sys error and repair didn't help. I then inserted a Linux live USB and started Memtest86+. It also froze. If I quickly press C and limit it to only the first, old 2GB chip it works fine, but once I let it run over the new one it freezes again. I also tried removing all 2GB sticks and tried the new one by itself to same effect.

I went to Sony's website and found on their page for VPCF13E8E/H (I'm guessing it's a similar model, because mine doesn't have the /H at the end and is not in their database) and found this page: http://www.sony.de/support/de/product/vpcf13e8e_h/speci... . It's in German, but I'm guessing you know what most of it means anyway. Under RAM it says that the maximum supported amount of RAM is 8GB.

My question is what I should do about it. Is the RAM faulty or is my system somehow incapable of using it? Should I try returning it (not sure if that's even possible for unpacked RAM) or is there something I can do to fix the situation? I wonder about the veracity of the 8GB limit claim, because, as I mentioned before, the BIOS does detect the full 10GB and Memtest86+ successfully reports them.

Again, I really tried finding the answer, so please don't yell at me for not being technically literate enough or lazy. :(

Those oem motherboards have limited bios adjustments for the ram. I would check your original ram for brand, voltage, anything you can find out about it and match it as closely as possible. Crucial guarantees it's ram to work if you order from their website using their configurator software.

I guess I'll try getting a refund then. Not much I can do with this chip. Thanks.

I'd like to expand on this. I returned the RAM and got a 4GB chip. The problem persists. I tested it on my Vaio and on a completely different model belonging to a family member.

I'm guessing Vaio laptops and Corsair just don't exactly like each other. Hopefully this will help someone.
