Windows 7: Patriot Sector 5 Ram is my ram bad? Or misconfigured in some way!

I currently have 8 GB Patriot Sector 5 DDR3 1333 ram. Got 2x 4gb sticks.

While running Windows Update I kept getting various BSOD. I took one stick or RAM out and almost instantly got a BDOD so I put the stick back in and took the other out and was able to update everything just fine.



I put the "what I think is the bad stick" back in a diff slot and went to update the Catalyst Control Center for my AMD Radeon HD 5770 GPU and when it downloaded and I tried to install it kept saying Integrity Error and wouldn't install.

So I took the "what I think is the bad stick" back out and re-downloaded everything and it updated just fine.

So, without downloading Memtest86+ and burning it to a CD and running it overnight. Sounds like just a bad mem stick right?

I am running
