As the title mentions, I can't have dual channel RAM installed AND have a GPU installed. Quick specs run down:
Intel E8400
Intel DQ45CB Motherboard (BIOS version CBQ4510H.86A, latest as of 8/10/2011)
4x2GB Kingston Value RAM (Low Profile) @800MHz (DDR2)
EDIT: Added link to RAM as per request of Calvin7.
Official stick: https://www.newegg.com/Product/Product.aspx?Item=N82E16820134581
I had purchased these for much cheaper and in a lot of four, however, on eBay.

EVGA GeForce GT 520 (Fermi)
(This variation is particular: https://www.newegg.com/Product/Product.aspx?Item=N82E16814130680)
EVGA 450 BT PSU
I have also tested each RAM stick individually, (one stick at a time) tested in all four slots and found no issues.
Now here's the weird thing. If I take out the GPU, I can have 8GB RAM in dual channel just fine, no issues, OR I can have 4GB RAM and the GPU installed. Just not both. If I have both, the POST splash screen loads slowly. I can see it drawing the image from top to bottom. Once it boots into Windows, it's usable, but there are delays of at least a few seconds, and more often than not the PC will freeze up entirely (I have to hold the power button to shut it down)
What could be causing this? I've tried doing research, but I can't find much. Not a lot comes up when I search "Dual Channel RAM with GPU causes slowdowns", or "Dual Channel RAM causes slowdowns/makes system unresponsive". There was a forum that mentioned a graphics driver issue, so I'll test that, but I don't see that being the problem. I also don't have any other GPUs to test in this PC to troubleshoot.
I've also tried messing with the speed, timings, and voltage. Did that for a few hours straight. No results, but one thing worth noting is that when I manually enter in the settings, the splash screen doesn't load slowly. It loads normally, whereas you can't see it draw the image. It gets to the Windows logo, and then BSODs with the error "KERNEL_SECURITY_CHECK_FAILURE."
