I've been running 4GB of DDR2 1066 ram for quite awhile, and decided to upgrade to 8GB. I found an identical set of sticks with the same part number as mine, and purchased them. Stuck them in my case yesterday and either won't boot, or will freeze up or BSOD within 3 minutes of booting.

Specs:
CPU: Intel Core 2 Duo E8600 Wolfdale 3.33GHz (stock cooler)
MOBO: Gigabyte GA-EP43-UD3L (rev. 1.0)
RAM: OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)
GPU: Sapphire HD 7850 1GB
PSU: Tuniq Potency PSU-POT550-BK 550W
HDD: Some Western Digital HDD @5400rpm and not close to being 1/4 full

Only difference I see with the new sticks and my old ones is that my old ram's pcbs were black, and the new ones are green.

I tried booting with both of the new sticks only, and rarely got to login to windows, and ended up freezing or BSODing. I put them all together, with my ram in slots 1 and 3, and the new ram in slots 2 and 4, and the computer became significantly slower to boot and would freeze more often than BSODing.

I then ran memtest86 on the new sticks, one by one, and no errors came up (5 passes). I then put all my ram together, with the new sticks in 1 and 3, and my old ones in 2 and 4, and ran memtest86 overnight. No errors came up the next morning, and 5 passes had been made.

I'm extremely confused on why my computer is BSODing.

I spent all night yesterday trying out different configurations and now my computer won't even boot. I've reset the bios to fail-safe settings. The motherboard should be able to take 1066mhz as it's stated on newegg, and has been running well with my previous 1066 sticks for over 3 years.
