Hi,

I tried figure out why I can’t set DDR3 Fraquency to over 1600 Mhz. I find this with AMIBCP.
Is there anything that I can do for it? It looks artificial limiter.

You can’t set memory speed over 1600 Mhz with desktop Haswell on H87.

Actually I don’t even believe that z97 and h87 chip is physically different.
