Memory speed-Processor memory compatability

Can you stick a 1600Mhz memory stick into a mother board that has a processor that says it can only handle 1066/1333? If you can, will this pose any problems in the future or benefit?

*Not willing to overclock. Prefer to stay with stock speeds*

Processor- i7 2600K (http://ark.intel.com/products/52214/Intel-Core-i7-2600K...(8M-Cache-3_40-GHz))
Says: 'Memory Types'- DDR3-1066/1333

Mobo- ASUS P8P67 Deluxe (http://uk.asus.com/Motherboards/Intel_Socket_1155/P8P67...)
Says: 'Memory Support'- 4 x DIMM, Max. 32GB, DDR3 2200(O.C.)/2133(O.C.)/1866(O.C.)/1600/1333/1066 MHz Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture

Memory- Corsair 16GB (4x4) DDR3 1600Mhz Vengeance Blue (http://www.ebuyer.com/262586-corsair-16gb-4x4gb-ddr3-16...)

Does the memory type of the processor need to match the memory speed of the memory sticks you are using? 
Can you get away with using a higher memory speed than your memory speed? Any problems going to be faced?

Finally, open for changes. Any components you think would be better like different memory or mobo. 

Thanks in advance.

You may want a z68 mobo, faster memory = better, i've never heard of anyone having issues with faster memory, otherwise no-one would buy or sell it. 16gb is overkill, 8gb is fine for anyone today

Anymore thoughts?
Faster memory doesnt break the processor, as long as the motherboard can take the memory speeds?
So can i get a 1800Mhz or something close to that and stick it in with the i7 2600k processor but the mobo can take it, will it still run fine? Without breaking the processor?
Is 1600Mhz high enough? 1800Mhz too high?

Thanks again in advance

memory speed pretty much only makes a difference in memory benchmarks and doesn't reflect on real world workloads so you should stick to 1600 kits

16gb, although might seem to be overkill, can be very very nice for ocassional ramdisk usage, and you'd also futureproof yourself

also, i agree with ali, z68 all the way (quick sync, ssd caching, pci-e 3.0 to name the few extras over p67); i tend to recommend asrock gen3 extreme3/extreme4 depending on the needs (extreme4 has 2 extra usb3.0 and sata3 ports, and a 3rd pci-e 3.0 slot; extreme3 is an absolute best bang for your buck, costing 50$ less than extreme4, and is the cheapest full atx z68 board on the market)

So you're saying that the memory capability on the processor has nothing to do with what speed of memory you put in but instead it needs to be atleast what the processor says its capable of?
And i will definately take a look at some z68 mobos now

yes, something along those lines

i mean you can get 2,4ghz kit but you will end up being disappointed by the performance 'increase' compared to basic 1,6ghz kit

you're much better off getting an ssd

I have the same problem and I don't understand why all the info I see says either 667, 800mz, or 1333mhz. I used my Asus bios, Cpu-z, and HWinfo32. (Screenshots of the last 2 below -- the bios says the same thing.)

HWinfo32 verifies that I'm getting Dual-channel mode OK (since CPU-z hates Sandy Bridge.) Can someone please help me verify that I'm getting 1600mhz out of each of my modules.

Let me know if I should post a new thread.

Thanks!

My system:
Intel G860 3Ghz
Asus P8Z68-V LE
4Gb DDR3 1600
Rosewill Redbone U3 case
Antec 430w 80plus Bronze

Oh, almost forgot. I tried both Auto mode and manual 1600 mode in the Bios. I didn't see a difference in the readings.
