Windows not reading speed correctly?

post #1 of 13
Thread Starter 
On properties, it says 2.14ghz cpu. On orthos and Core temps, it says 2520mhz.
Why is windows not reading it correctly?

probly speedstep thottleing it down when windows starts so it shows a lower speed. My pd will boot up at 3.0ghz and when i toss a load on it goes up to 4400mhz unless i turn c1e and speedstep off.

So it is running at 2.5ghz but windows only sees it as 2.14ghz because of speed step. how do you turn speed step off? or does it really matter?

If you are running a lower multiplier than the stock, you will get faulty readings by looking at the Properties of My Computer.

Downloading CPU-Z.

CPU-Z should tell you your right idle clock and load clock. If your clock is idling lower than what you overclocked it too, you have C1E, speedstep, or some other option that declocks to power save while you are idling.

On the DS3, it is called C1E and I love the option. I have no need to run 2.9GHz during idle.

cpu-z says that it is 2.15ghz. why is core temp and orthos still reading 2.5ghz?

That is the default speed of the CPU that you are seeing. Those programs and windows show the default speed, regardless what speed it actually is.

Because "2.14Ghz" is imprented into the identification microcode of the CPU.

If you were to right click your My Computer icon and select Properties you should see "Intel(R) Core(TM)2 CPU 6420 @ 2.14Ghz". As far as the operateing system is concerned its just displaying characters that identify the model of CPU that you're useing. Underneath that identification should be a second speed and this is the speed that your CPU should be running at.

To your operateing system, "Intel(R) Core(TM)2 CPU 6320 @ 2.14Ghz" is no different than "Intel(R) Pentium(TM)4 650", its howing the CPU model number by refering to its built in identification microcode. For some reason Intel have once again seen fit to include the default operateing speed of their CPU's into the microcode. The stopped doing this with the advent of the LGA775 Pentium 4/D CPU's but have started doing it again with their Core 2 based products.

Mine shows the correct speed...

The default operating speed is 1.86ghz. and its showing 2.14ghz in the properties after I overclocked it.
In properties, it read 1.86ghz @ 2.14ghz. Then it says 2550mhz in core temp and orthos, and it cpu-z it says 2.15ghz. What is it? My FSB is at 360mhz if that helps...

I understand what you're asking now, it looks as though EIST is simply lowering your multiplier when the CPU isn't under load.

360 x 6 = 2.16Ghz
360 x 7 = 2.55Ghz
