Is that with or without CPU PLL Overvoltage enabled?
Also, drop your BLCK back to 100 as it too can cause POST/boot loops.
You have a "K" processor and there really is no need to increase BCLK when you overclock unless you are trying to squeeze every last bit of OC out of your CPU for a suicide run or benchmark day. For general daily use, leave the BCLK at 100 and just go as high as you can with the multiplier and be happy with the result.
102.2 x 46 = 4701.2Mhz
100 x 47 = 4700Mhz
Yor really will never notice any extra performance in that 1.2 Mhz extra you gained by increasing the BCLK

I had the POST/boot loop with earlier bios and CPU PLL Overvoltage enabled when trying to reach 5ghz. I had to settle for 4.8Ghz.
I then started trying the "beta" bios' that ASRock were releasing for Ivy Bridge, and even though I had an SB, the "beta" bios' removed the POST/boot loop for me.
After all the testing and multiple "beta" bios releases, ASRock has released the stable bios that was based on those beta bios. Bios 2.10 is BIG step forward for the ASRock Z68 mobos. It not only adds Ivy Bridge support, but it fixes almost all of the bugs that were present in the older bios releases - including fixing that POST/boot loop.
I now use bios 2.10 in my ASRock Z68 Extreme4 Gen3, and it has allowed me to reach a higher overclock at lower vcore and runs more stable then it has run with previous bios releases. And I don't have the POST/boot loop with it.
