I've got an ASRock H67M mobo with an i5-2500 CPU. I had been running a utility I copied from one of my laptops, "Intel (R) Turbo Boost Technology Monitor 2.5", a little gadget that displays the instantaneous processor speed. Typically it shows 3.3 GHz (base) and every few seconds bumps up to 3.4 or 3.5 then back down again (the higher numbers are in a lighter shade of blue than the base 3.3 GHz).
So for some reason I decided to be stupid, and I ran the ASRock Extreme Tuning Utility, since I was encoding with Handbrake and thought I'd see if I could give it a little boost. Even though I'm not supposed to be able to overclock a non-k CPU.
As I recall when I first ran the ASRock utility, my default CPU ratio was set to 16. So I bumped it up to 17 and everything seemed fine. Except the Intel monitor utility showed nothing, no bar. Instead of the blue bar sitting at 3.3, it was gone. Then I ran the 64-bit version of TMonitor, and it showed me a flat 1600 MHz across all four cores. So I eventually discovered that if I used the ASRock utility to bump up the CPU ratio to 33, the Intel monitoring utility looks normal again while encoding with Handbrake. The blue bar is there at 3.3 GHz.
But I shouldn't have to overclock the utility to get back to 3.3 GHz, the i5-2500 is supposed to run at that by default, especially when Handbrake is pegging all four cores to 99.9%. And I seem to have lost all TurboBoost, as the CPU sits at whatever the ASRock OC'ing utility has the CPU ratio set to. I've checked in the UEFI/BIOS and the OC section is set to "Auto", overclocking not "Enabled" in UEFI/BIOS.
Have I screwed things up, or is this behavior normal? For one thing I thought the non-k version of the i5-2500 wasn't overclockable, so how come I can take it from 16 to 33? And why do I have to overclock it to 33 just to get it to run like it should?
Any help would be greatly appreciated. Worst case, I'll clear the CMOS/BIOS and start from scratch, but if anyone knows what's going on, I could use some enlightenment.
