Tx for the advice Kendo, but it seems that Intel® Core™ i7-2600K is not DDR3-1600 compatible.

Actually, i'm sure that it is - i'm using DDR3-1600 memory with my i5-2500K.

I do recall seeing some confusing info that suggested 1333 was the fastest I could use without overclocking, but that turned out to be due to limitations of certain motherboards rather than the Sandy Bridge cpus. My Asus P8P67 runs DDR3-1600 at stock settings and I could easily plug in a i7-2600K if I wanted.

One additional piece of advice is to get 1.5V memory for Sandy Bridge rather than 1.65V - ensures the CPU is running at correct settings and helpful if you overclock.

Edit: Did some reading - officially the SBs are in fact only rated for up to DDR3-1333 memory, BUT...they can run 1600 and higher. Tests done by custom PC magazine (UK) found benefits from running 1600 over 1333 (a few fps in some games) but no real benefit from going for 1800 or 2133. Hope this all makes sense.
