My E6750 has only a Core Speed of 2000 MHz

I asked this question and several others in the Home Build forum but didn't get any answers... I think I gave too much info and asked too many questions. So I'm going to break this down into seperate questions in approrpiate forums... Sorry if you read this in the Home Build forum:

I just put together my first build yesterday:
Intel E6750 CPU
Gigabyte GA-P35-DS3P motherboard
EVGA 8800 GTS 320 MB
2GB (2x1GB) Patriot ExtremePC-6400 (DDR2 800) Low Latency Memory
Sony/NEC Optiarc SATA DVD+/-RW
Corsair HX620W PSU
Cooler Master Hyper TX2 CPU cooler
Antec P180B Case
Windows Vista 32-bit

The BIOS is AWARD, Version F5h dated 7/24/07.
some BIOS settings:
Advanced BIOS Features:
Limit CPUID Max. to 3 [Disable]
CPU Enhanced Halt (C1E) [Enable]
CPU Thermal Monitor 2 (TM2) [Enable]
CPU EIST Function [Enable]
Virtualization technology [Enable]

MB Intelligent Tweaker
Robust Graphic Booster [Auto]
CPU Clock Ratio [8x]
CPU Host Clock Control [Disable]
CPU Host Frequency 200
PCI Express Frequency [Auto]
C.I.A.2 [Disable]
Performance Enhance [Turbo]
System Memory Multiplier (SPD) [Auto]
Memory Frequency 800 800
High Speed DRAM DLL Settings [Option 1]
System Voltage Control [Auto]
DDR2 OverVoltage Control Normal]
PCI-E OverVoltage Control [Normal]
FSB OverVoltage Control [Normal]
(G)MCH OverVoltage Control [Normal]
CPU Voltage Control [Normal]
Normal CPU Vcore 1.35000V

I ran CPU-Z V1.4:
Under CPU tab, for the Clocks (Core#0)
It shows a Core Speed of 2000.0 Mhzand a Multiplier of x6.0 and Bus Speed 333.3 Mhz and Rated FSB 1333.3 Mhz. Basically the same thing in RightMark CPU Clock Utility.

Why does it show the core speed of 2000.0 MHz and a multiplier of x6?

More about e6750 core speed 2000
  1. try disabling the eist and set the multiplier to what it should be then look at the speed in the BIOS not the OS

    when i oc my q6600 it is shown correctly in the BIOS but not in windows
  2. Speedstep is working.

    Load Orthos while the cpu-z is running, and the correct multi and clock speed will show.

    Keeps you running cooler when you are idling along. It is kinda like using the clutch going downhill when little driving effort is needed, and as you hit the next load, it spools back up to full speed in a nano second to work for you.

    You can disable it in the bios, prolly under advanced chipset features somewhere, I am not familiar with your board.

    Google will give you a better tech explaination as well.

    Core temp and speedfan are invaulable as well. Core temp to give you the skinny on the temps of the cpu, and speedfan will show load on each core and Hard drive temps.

    Also notice the voltage diffs at 2k clock vs the 3k clock speed in cpu-z. That is where the heat and energy comes from.
  3. speedstep
  4. *sigh*

    It's called SpeedStep, it automatically lowers your CPU speed when there is little load on it to save energy, but don't worry, it will run it at full speed as soon as you start doing something CPU-intensive.
