hello looking to do full upgrade and i will be getting the crosshair 5 but running my 955 be for awhile and i what to know if getting 1866 will work on the 955 or will it be down clocked/even boot. and what is some good 1866 ram 8-16gig kit as i dont what to upgrade for couple yrs...

That's because they're 1.5v

and 90% of the time you wont notice ANY difference

so would be waste money i should by another 8 gig kit of the gskill ripjaw x and clock the s high as i can and tightin timings.

in the real world, you will notice an extremely tiny difference if any at all. In benches, you will notice. But, thats what benching is for.

If your current ram is 1.65v I would get another kit of it to match instead of the 1.5v ripjawx.. just match whatever you currently have.
Phenom II's love lower timings so keep them at 1333 and tighten up the timings.

This question gets asked frequently.

YES it would be a waste as objective testing by Tom's Hardware, AnandTech, X-Bit Labs and OCN member "damric" confirm no significant gains in real world applications with RAM frequencies above ~1333 MHz. or tighter latencies on both AMD and Intel desktop PCs. As the frequency increase the real time of one clock cycle becomes less so tighter timings do not show gains either in real applications. For all practical purposes DDR3 RAM @ ~1333 MHz. is not a system bottleneck on a typical desktop PC which is why you do not see substantial gains.

The definition for "significant" in this case means if you can't see it or feel it, then it's not significant. Your 955 is very unlikely to run the RAM @ 1866 MHz. anyway but an FX or Vishera/PD will be able to use the 1866 MHz. frequency as the default speed.

It's worth noting that AMD Llano APUs are the exception as the GPU section of the APU does benefit from being able to use higher frequency RAM.
