I7 950 Multiplier fluctuates in CPU-Z


New to the forum here and I've been googling the hell out of my question to see if this is normal or not, but here is my dilemma. I recently built my rig and everything seems to be running fine, but I've noticed in some of the windows widgets and CPU-Z that the multiplier for my CPU is bouncing all over the place. At first I thought it was as simple as disabling the Intelligent Power Savings in the BIOS, but that didn't do it. I just simply want to know if this is normal for this CPU to hibernate like this until the power is needed?? If at idle or close to idle.. it is reading at x12 which is close to 1600MHz. When I seem to throw some multitasking at it it will jump up to x24 which is close to the 3.06Ghz. If anyone has any feedback please let me know...

  1. Google Intel Speedstep, thats what it does, power saving management. :D
  2. AMD has the same thing its called Cool and Quiet, even the iPhone and some phones with Android on them do.
  3. i7's automatically OC a few steps when below thermal threashold, could be that too...
  4. Thanks guys. After reading into the Intel Speedstep, I guess the answer to my question has been answered.. that it's normal. I'm leaning towards disabling it... any of you guys advice against that for some reason?? Any notice in difference in performance when it's enabled? Thanks for the feedback... when I get home I have to look in BIOS again to see if the Speedstep is in there.
  5. I would leave it on unless your overclocking, but I left Cool and Quiet on even when i was OCing.
  6. I'd personally leave it enabled. It makes the chip run cooler and with less power, and has no real detrimental effect on performance.
  7. Great guys. Thanks for all the feedback. I will leave it enabled. I was just concerned at first, but notice that CPU-Z has it running close to full speed when I throw some heavy multitasking. I've been an AMD guy since the k5... this is my first intel build. It was a toss up between this and the AMD 1090t. Glad I went with the Intel... seems to be pretty sweet. Gonna mess with overclocking once I get it underwater... but she's running at 39deg right now. Thanks again....
