I have a machine that I was using as a whitebox ESXi host that I'm trying to hackintosh now. it's an MSI H87-G43 motherboard with an i5-4670 (3.40GHz) quad core.

I was able to install Sierra without any problems, just needed kexts for the onboard Realtec 1GB NIC, but other than that everything seems solid.

As it's a Haswell CPU, I'm using iMac14,2 SMBIOS in clover. However, when I boot it says my CPU is stuck at 800Mhz. Not just cosmetic either, my geekbench scores are like 900 single core and 2000 multi core, so its definitely running at 800Mhz as it says. I've gone into the CPU section of my config.plist and manually set it to 3400, which then results in a nominal increase to about 1500 single core and 3000 multi core. Further setting the bus frequency does improve performance slightly, I've tried 133330 which is very stable and results in a multi core score on GB of about 4000. I've also tried 1666667 which makes the system seem more sluggish at times but results in a multi core score of about 5500.

Setting QPI has no effect.

Given the machine's specs 3.40 GHz quad core i5, 24 GB DDR3, I estimate my Geekbench scores should be 3-4 times higher.

any help on this would be great
