Suchen Sie nach einem Gadget (oder etwas anderem), um die tatsächliche CPU-Geschwindigkeit in Win 7 zu ermitteln

Ich suche ein Gadget oder ein beliebiges Programm, um mir meine wahre CPU-Geschwindigkeit in Win 7 mitzuteilen. Ich habe einen Xeon 3426 . Ich verwende das Intel Turbo Boost-Monitor-Gadget, aber es geht nur auf 1,87 GHz. Wenn ich Ubuntu lief, lief meine CPU im Leerlauf auf 1,2 GHz. Ich möchte sehen, ob es in Win 7 nicht richtig läuft.

It is possible that SpeedStep is working properly, and your monitoring tool just isn't showing the actual speed below 1.86 GHz. CPU-z, though not a handy little gadget you can just glance at, would be useful for diagnostic purposes. It will tell you the exact clock speed, and will update as the processor's speed changes. I had the same confusion once, since windows wasn't reporting the speedstep adjustments, but it turned out they were happening.

By default, the "Balanced" power plan uses speedstep moderately, the "Power Saver" power plan uses speedstep aggressively, and the "high performance" power plan does not use speedstep.

Vielen Dank. CPU-Z funktioniert. Ich wusste bereits, wie meine CPU funktioniert, und ich habe bereits "All CPU Meter", aber ACM zeigt nicht den tatsächlichen GHz-Wert an, sondern nur Prozentsätze. CPU-Z hat bestätigt, dass meine CPU auf 1,2 GHz läuft und auf 3,2 GHz ansteigt. Der Intel Turbo Monitor zeigt nur Boost, nie unter 1,87 GHz. Cyrcle vor 13 Jahren 0

That processor has Turbo Boost, and SpeedStep.

It's got a 1.86GHz clock speed.

Turbo Boost will shut down sections of the chip in order to boost the clock speed of some of the cores. This is done when there are a couple/few CPU-intensive threads active, and dynamically. it's so you can get more power for a short time, with the same overall power consumption (basically).

SpeedStep is related to power savings. When the chip is less busy (but not idle) SpeedStep will slow the clock down so that it's consuming less overall power. It ramps back up to the default clock speeds when the system becomes busier. It slows down and speeds up in 3 (or more) "steps", depending on how busy the system is.

I think even the 'default' Windows CPU gadget reflects this, and I know there are other popular ones in the Gadget Gallery that do reflect it for sure (I used one for a long time). And, since SpeedStep is implemented in Ubuntu it works, and also reflects it.

So it sounds like you're Windows 7 is not set to use SpeedStep.

Check your Power Options and ensure it's set to "Balanced" or lower, as "High Performance" will keep the CPU clock at 'full speed' all the time by disabling SpeedStep.

The 'full speed' of CPUs with Turbo Boost is all cores running at the same advertised clock speed (four cores at 1.86GHz in your case).

If you click "Change Plan Settings" to edit the current power plan, then "Change advanced power settings", you can them expand "Processor power management" in the tree and set the Minimum and Maximum Processor states.

The minimum should be like 5%.

Also, ensure SpeedStep in enabled in your BIOS. :)

The name you're looking for is All CPU Meter. Just install the gadget in your Vista/7 system and off you go. =)
