I7 2600k

[tyler94]

is it true the i7 2600k can only handle DDR3-1066/1333 and not 1600

What this means is that AT BOX is that the intel i7 2600k would support the 1333mhz.In other words.you have to Overclock your ram to use its full function such as if you bought 1800 ddr3 ram at initial installation you would get 1333mhz.

To get the full 1800mhz worth of ram you bought you would need to OC your ram.And yes it supports speeds way more higher than 1333 ddr3.

It doesnt mean that it wont support higher speed rams.But you would need to overclock your ram.

Intel set the memory controler on chip to 1333/1066. With the right motherboard and the right ram you can minipulate the ram settings in the XMP controler on the ram. This only works for settings of 266. 1333 +266 = 1600 +266 = 1866 +266 = 2133 Which I believe is about the limit.
The are trade offs. Lower latency can be more effective than overclocking.

Overclocked cas 9 might go to cas 10 in overclocking.
You will see memory ratings like 1600 cas 8, or 1866 cas 7.
This does not mean some 1333 memory cannot run at lower than rated latency and overclocked, but it may not.
The on chip memory controler is rated 1.5 volt, Intel specifies an upper limit but there has been (wink wink ) 1.65 volt usage.
Some pre Sandy Bridge memory is still around with original 1800, 2000. 2200, ratings, purfectly usable in most cases.

The 2600k doesn't support anything .... it's the MoBo that determines what RAM is supported. P8P67 Pro for example supports:

1600/1333/1066
2200(O.C.)/2133(O.C.)/1866(O.C.)
