Pentium D 925 @ 3752.5 for a split second?

I was browsing the internet with CPU-Z open next to Chrome, my computer was unresposive and under load, that is when i saw my core speed hit 3752.5 for a split second, before someone asks i have not overclocked this as I own a OEM board. I am not worried, just a little surprised to see my core speed up 700mhz from stock. This has happened quite a few times since the first about 10 minutes ago. What do you think?
 
I dont think so, It only happens when it goes from slightly under load to extreme load, kind of compensating if you know what im saying
 
I really think it's just the cpu z glitching out under load. I think I had a rana chip that did the same, it jumped up to something crazy like 8ghz but I only saw it happen once while running prime95.
 
Mine has happens loads of times under my watch and problably has been gping on for months, thing is the multiplier and fsb also change and they match the speed given
 
Of course they do... it's probably not measuring all 3 at the same time, it's measure FSB * Mlt... Clock/Speed is just a result of that.

If the FSB and Mlt measurements are related to each other (same time-frame/cycle), it will show the clock/speed accordingly.

FSB: 166 200 233
MLT: 15...18...15

But... if those are out of sync (off by one, etc)... it will use the wrong multiplier for the wrong FSB.

FSB: 166 200 233
MLT: ----15...18...15

The CPU could be running within normal frequencies, but the software is reporting what it observed, which was wrong.

If your CPU was actually spiking to 3.7GHz from 3.0... you'd be crashing.

So... whatever CPU-Z uses to measure the FSB/MLT is somehow wrong... if that's "new" then maybe a driver changed, maybe your virus scanner/hips did... maybe one of the sensors is dying.

Check your event viewer for oddities at the same times CPU-Z reported odd speeds.
 
Man let us all pray for you to get a upgrade. My old man had a Pentium D @ 3Ghz,. biggest slouch ever, I thilnk the P4 might even pown it with its single thread.

I vouche you upgrade. total cost, 300 dollars. Buy a mobo for 100, cpu for 150 and ram for 35 dollars. Please do it cuz I know what your going through with that machine,.,, gb
