My advice would be to:
1. Turn off the PC and unplug the power
2. Install one stick of RAM in DDR slot 1 (according to your motherboard manual, it's the slot furthest away from your CPU)
3. Clear your CMOS using the Clear CMOS button
4. Go into BIOS screen and choose "Load Optimized Defaults", save and exit
5. Run Memtest
If you get errors, swap the RAM sticks.
If you don't get errors, add the second stick in DDR slot 3 and repeat steps 1,2,5.

There's also the small possibility of it being the power supply.
If each stick individually causes so many memtest errors, together with the fact that you have confirmation that they do not in another PC, then it's likely not the RAM. If you've tried these ram dimms separately and in different slots and get the same error rate, then it's likely not the motherboard either. This leaves the CPU. The other possibility might be that pins linking the memory controller to the ram slots on the CPU socket got slightly bent out of place when you installed the CPU and is not making a consistent contact.
Unfortunately the only way to really trouble shoot a problem like this, after you've already tried each individual ram dimm in different slots, is to swap with a known working part, starting with the least expensive/most likely of culprits, which would be the ram.

If you really want the 1600MHz you're going to have to pump more voltage into the memory controller. Going past 1.575 isn't recommended by Intel, but your mileage may vary.

Why didn't anyone tell me that before? I posted this on 4 different forums a while ago!

MatiasMGS wrote:It probably just means they tested the RAM only on AMD platforms. So the fact that it is not working on Intel platforms, and on the somewhat unofficial speed of 1600MHz, is just coincidental.cynan wrote:Did you try lowering memory timings to 10-10-10-30 and running at 1600Mhz?
I'll try that tomorrow, thanks for the explanation. My guess is this happened because AMD RAM isn't really meant for Intel platforms?
Try command rate 2T, tRFC to 300ish and tWCL (or tWL, whatever it's called on Gigabyte) to 8. If this doesn't help, then it gets down to adjusting other subtimings via trial and error method.
