Aida64 FPU Testing Throttles CPU

Title says it all

I have an AMD Athlon X4 860k Quad Core Processor OC to 4.20GHz with a Liquid Cooler. I was stress testing my CPU alone and max temp for the MotherBoard was 48c while Cpu was 56c (CPU Temp limit is 70c) and running at max speed with no throttle. However as soon as I attempt to stress the FPU it throttles to 1.60ghz for about 2-3 secs and goes back up and then loop. Should I downclock to 4.0ghz and below? (Same results at 4.10ghz) I used EZ OC Mode and sets it to 4.10ghz at 1.4v while 4.20Ghz is at 1.4500v

 

Motherboard is an ASRock FM2A58M-VG3+ R2.0

 

Bio settings

CPU Spread Spectrum Off

Cool and Quiet On

CPU C6 State Off

 

Temps while playing games are avrg 26c from MSI Afterburner OnScreen Monitor (CPU Core Temps are all the same temp rather then separate numbers if that helps)

 

It was given to me from my brother and he had it stabled at 4.20GHz with OC Ram and had it in a tight corner and told me he hasn't had any issues. He's used it for over 4-5years

 

Any help will be appreciated! Oh yeah I also have the fan set to normal speed and never touched it if that helps

If that's the case, how do I check the temp for vrm and should I underclock?

open the case and blow air directly onto the board with a desk fan, if that solves the problem, VRM is overheating
