Physical Memory Upgrade

I have an Acer Extensa laptop. I am runnung a Kubuntu host and a Windows Vista guest with 512 MB ram, 8MB video memory on VirtualBox 3.0.4. All was well until I upgraded my RAM from 2 GB (2 x 1GB DDR2 PC2-5300) to 4 GB (2 x 2GB DDR2 PC2-5300). Immediately following the upgrade, my VM would no longer boot. Instead, it would freeze the host system, which required a hard reboot. I reinstalled the old memory and the VM worked flawlessly. I tried the procedure again with the same result. Any advice? I would really like the benefit of the added RAM.

Sounds more like a ram module problem or the machine can't handle 2x2, try a ram test lifeCD, or 2+1.

My host boots properly and I can run the memtest ok. I only have a problem when I attempt to run my VM. Everything else runs fine.

A Host hang with memory expension is a typical hardware issue....

Run the memtest is ok, but what if you leave it running for a couple of hours? Let it to at least 2 passes, 5 advised. More is always better, but it takes longer too though.
