Forgot to mention I will be getting the Asus P7P55D-e Pro board for this setup.

Yes. I have that same MOBO. It can handle far more. Those specs are intel specs without overclocking. But to get up to 1600mhz requires overclocking.

While this is true for most socket 1156 CPUs - it is not true for the i7 860 and i7 870.

notez2id,
With an i7 860 you will be able to change your memory multiplier to get RAM running at 1600 MHz. If you had an i5 750 or one of the Clarkdale chips (i3 or i5 6xx) then the fastest your could run your RAM without OCing is 1333 MHz.

Of course there is not much benefit in running RAM at 1600 MHz outside of synthetic benchmarks, but that is another question altogether. http://www.tomshardware.com/reviews/core-i7-870-1156,24...

Answer from New Zealand:-

Mine is solid and stable--and configured as follows---Win 7 64bit.
Asus P7P55D-E Pro with i7 860 and Zalman CNPS9900nt Cooler on top. The i7 860 1.24v core; Running at bus f of 160.65 x 21 Multiplier = core of 3373.7Mhz This is oc'd from2.8Ghz Normal 'work' temps in the 4 cores = 30-35deg C. ( Free 'Core Temp' Program v99.7.10 64bit

Corsair 4GB (2x2 in Dual) PC-12800 1600Mhz DDR3 (XMS3(in bios too)CL9-9-9-24 Manual Dram v set in bios to 1.65volts

EVGA GTX460 SC (factory superclock) 1024MB Gddr5

Corsair HX850watt Power supply

Samsung 2493hm 24" native 1920x1200x60 Monitor on digital drive

All the latest drivers i could find for everything.
Will post jpgs of cpuz etc in separate post.

Impt Note-----Above setup was orig with i5 760---no matter what combination of what;; i could not get anything stable-even 100/133 settings--no good.Plus diff ram like ocz etc-----Gave up on the i5 760 in this setting...rma'd and for nz$100 more the
i7 860 (configured bios) and booted to solid performance not a hint of a problem now.
I believe i5 760 must stay with absolute default specs...to work stable. ie 133bus--1330ram--x21mult--=2793Mhz(~=2.8Ghz)

i5 seems to like the 133 and the 1333 and the x21native multiplier set up as a combo.It does not like 1600.--------- i7 860 is a far better solution for a little extra money IMO-----

The sorting out of all this drama in this new build took me 3weeks off and on. All components tested error and problem free.
isolating out that i5 issue in this setting was a real test on patience.

I was about to post my new build right here when i saw your message.I will now post mine .Hope this helps you.
