Any help appreciated 
My initial Overclockers.co.uk system was: Gigabyte X58A-UD3R, i7 920 OC'd to 4GHZ, 3x2GB Corsair Platinum TR3X6G1600C9 1.65v ver2.1
I bought another 6GB RAM from overclockers, being told it was completely compatible with the existing memory. I received 3x2GB Corsair Platinum CMX6GX3M3A1600C9 1.65v ver2.3A (9-9-9-24).
It installed and ran fine, but after a while I noticed lower performance than before, and when I ran OCCT discovered the chip had reverted back to 2.67GHz and not 4GHz. When I tried to reload the previous O'clocked profile from CMOS the computer fails to boot into windows.
A phone call to tech support said 12GB systems can't be OC'd....or try the forums. So here I am.
Aside from throwing away the extra memory, what manual settings do I need to change to overcome this problem?
It's not that I'm too lazy to google the answer...there are too many conflicting answers out there, and they all seem to be based on 6GB systems. I just want my photo processing to run at similar speeds as it used to, whilst having enough memory to run a linux virtual machine in parallel.
Many thanks,
Simon
