Looped Restart When Trying to Add new Memory

[Computer NC]

Alright a friend of mine gave me 8 gbs of ram today to go with my already 8, try to install it and it works fine. Then I restart my PC and it gets stuck in a restart loop so I remove one stick and it boots fine with 12 gbs. One more restart and that decides to put me back in the restart loop. Only starts with my original 2 so my question is how can I get this working?

My Memory

New Memory

Motherboard is the Z77A - G45

NEVER a good idea to mix DRAM, but as long as you have them, start with one set, go into BIOS enable XMP, then raise DRAM voltage to 1.565, save, exit, shut down, add aother sticks and try it - let us know what it does

Im starting to think I should just stick with the 8 gb I have at this point. Earlier it decided to loop with my original 2 and would only start with 3 in, then I gave the voltage rise a try and it refused to start with more than 2. Honestly I have no idea what is going on right now, at times 4 works, then 3 then only 2 just seems to be unpredictable so I guess I should stick with the original 2?

Also I was looking at the Memory and comparing things and the timing is different as well as CAS Latency, could that be causing problems?

Try at 1600 9-9-9-25 1.565 and look for CPUVTT or DDRVTT set to 1.14
