AMD 8350, CPU 100% utilization only running at 1500 MhZ???

Title basically describes it - I upped the FSB on my motherboard to 220, vs. stock 200, so my CPU should be clocked at 4.2GhZ right now (220 FSB x 20 multiplier) but in HWM, my clock speed is 1500MhZ when it's being used 100% by Prime95??? I always felt like my CPU wasn't as fast as it was supposed to be, but if this is the case, then my CPU is operating at less than half of what it should be. This thing should be at 4200MhZ right now, and it's at 1500. Please advise!

Motherboard: MSI 970 Gaming



Edit: I checked, and for some reason on my motherboard BIOS, my voltage is set to .912....the default voltage being 1.325???
I'm wondering if for some reason my motherboard is throttling my CPU???

Double edit: My CPU multiplier is at 7 right now, vs. 20, where it should be at. I don't know why this is the case, but I would really like to be able to actually use more than 1500MhZ of my 4000+MhZ processor. So frustrating.

1| Are you on the latest BIOS revision?
2| Does reverting your FSB to 200 bring those specs back on track?
3| Instead of the FSB, why aren't you working with the multiplier and managing your voltages?
4| If you didn't know you're trying to perform an overclock so if anything we need you to be sure your cooling on the CPU and the power delivery area on the motherboard's CPU socket is more than adequate.

1. yes, I should be.
2. no, if I revert to FSB 200 then my core clock goes down
3. usually FSB overclocks provide a much more substantial improvement, because of RAM speed increase as well. I did overclock it to 5GhZ with multiplier and I didn't notice any improvement at all, hence why I'm trying this with FSB
4. I'm on a 240mm liquid cooler, my CPU never goes above 30 degrees.
