Memory speeds above CPU supported

[nothingspecial]

Ok, might be an odd question, but here it goes:

Sandy Bridge chips support 1066 or 1333 DDR3.

Gigabyte GA-Z68X-UD7-B3 supports up to 2133 DDR3.

Is it worth buying 2133 sticks if the CPU is going to bottleneck it? More to the point, does it bottleneck it?

you can manually adjust them to w/e you want, just will take a bit of time

what makes you think the cpu will bottleneck (i hate that word) the ram?

i mean its the bios that controls the cpu:ram ratio so if the board will do it your ok.

I thought the controller was on the CPU? That's confused me even more now!

oh it is

what it means is it will only detect and set the ram at those speeds, it works all the same with faster ram but you need to set the volts/timings/ratio yourself.

i cant recall which but im sure i was reading about one board that has a 2400mhz ram ratio on the 1155 socket which is near double the stock max but as there is ram out that fast and no way to oc the base clock to manipulate the ram speed (not much anyway) they need to add the ratios to support the ram.
