Using Slower Ram - 1600MHz Instead of 1866MHz

Hi guys, i plan on getting a new mobo. this one

and a new cpu, this one

I dont have teh cash to get 1866mhz ram, i have a pair of 1600mhz ram, will it work with the build? If so, will it force the chip to downclock?

 

Ram should work as the onchip SPD will tell the Motherboard what clock speed its spec'ed at. I'm using old ram myself until I can buy higher density and faster ram.

 

if you are worried about performance loss, don't
i have 1866 ram, i have tested it at 1866,1600,1333mhz

if you adjust timings properly, there's no performance loss

1866 at CL9 is the same as 1600 CL8 and 1333 CL7

 

hmmm. so there is no ratio x ram speed thingy (you guys know what i mean) like in the old days?
