Yosemite Ram not correct speed

Hi. my ram is a kingston ddr3 1866mhz ram. the bios reads this correctly and so does windows however my os x does not.

On Clover?

Let's assume you are

1. Open your config.plist with Clover configurator;
2. Navigate to SMbios;
3. Tick the box 'trust';
4. Save config.plist;
5. Reboot.

That got my speed displayed correctly.
