BTW, anyone who is going to explore the limits of your CPU/RAM would be wise to download BIOS V1.8 and V1.9, unzip and load them both on to a USB flash drive. The reason for this is that the Asrock BIOS can get confused and go into a "stupid loop" if you have a crash or need to power down for a freeze. Sometimes disconnecting power from the PC for 10 seconds will clear things, but not always. Sometimes the BIOS re-set button on the back of the case/mobo will re-set things but not always. Storing your favorite BIOS configs. is helpful.

When the BIOS goes into it's "stupid loop" you will see wierd things like when you make BIOS changes to CPU/RAM frequencies, they do not actually change, even though the BIOS shows them as changed. The only means to fix the confused BIOS chip, without replacing it, is to flash to the other BIOS version you have on your USB drive. Use the 2.0 USB port and Instant flash in the Advanced screen. Otherwise you'll think that you're testing a configuration that you really aren't.

I use Core Temp, CPU-Z and OCCT to quickly check what the real frequencies, latencies, etc. are. You can boot into Windoze with the newly loaded BIOS and then re-boot and flash back to the original BIOS version you were using and all will be fine.
