Intel Pentium D 830 3.00GHz - Smithfield - Speed of Cores

[ScottDmac]

Greetings,

I have an Intel Pentium D 830 3.00GHz - Smithfield.

When I run “Intel(R) Processor ID Utility” it states that following:

Speed Expected “ 3.0 GHz”
Reported Core 1 “1.66 GHz”
Reported Core 2 “1.66 GHz”

Should each core report 3.0 GHZ?

Thanks

Speedstep. Turn it off if it bothers you, but I'd leave it on because its a netburst CPU.

download cpu-z (search in google). Install and run it. Post the screen.

After I disabled “On-Deman Clock Modulation” in BOIS it reports 3 GHz for each core now.

Thanks.

As I said I'd leave that enabled seeing as you have a P4. Wouldn't make a difference either way performance wise. But you should see a decrease in heat output.

But, but but!

Speedstep is a good thing.

Why didn't anyone explain it to him?

Not to mention, speedstep doesn't ever go that low on a smithfield. 2.8 GHz was the speedstep "idle" speed.

I suppose so, but any power saving is better than none.

I’m keeping Speedstep enabled – Don’t seem to hurt in anyway.

When “On-Demand Clock Modulation” is enable to Auto it cuts all the speeds in half for the CPU. No idea why but I’m leaving it disabled because there is a huge gain. (Double the FPS in games) CPU does run hotter but in normal range.

Thanks all for your input.

It should clock back up to full speed once a game is loaded. You should see no difference in performance.

All I can tell you is ever thing slows down with On-Demand Clock Modulation enabled to Auto.
I can confirm it does by my FPS in game.

Intel(R) Processor ID Utility reports each CPU running at Core Speed @ 1.65 GHz and System Bus both @ 440 MHz with it enabled.

With it disabled Core Speeds each @ 3.0 GHz and Both System Bus at 800 MHz.

CPU-Z only shows one CPU and the results are always the same with it enabled or disabled.

This is what I have enabled in BOIS right now but I tried every different variance. Same results.

Boot Failure Guard – Enabled
Spread Spectrum – Disabled
Enhanced Halt State – Enabled
CPU Thermal Throttling – Enabled
No-Execute Memory Protection – Disabled
Intel Speedstep Tech – Enabled
On-Demand Clock Modulation – Disabled.

BOIS
American Megatrends Inc.
Version: P1.00 “updated to p1.30” Made no difference.

Thanks.
