Pentium 4 Throttling Program

Hello everyone, I'm searching for a program with one function: controlling CPU speed. My Toshiba Power Management utility only down clocks this bad boy to 1.84GHz, leaving me with around 2 hours of battery life max. Undervolting is not an option for the P4 as it is somehow locked. Additionally, if we could avoid NHC, I'd really appreciate it as it is too multi-functional and so takes more resources than I'm willing to spare. I'm just looking for a P4 throttler. Thanks to those who look.

 

RMClock...

 

RightMark CPU Clock Utility (RMClock) is a small GUI application designed for real-time CPU frequency, throttling and load level monitoring and on-the-fly adjustment of the CPU performance level on supported CPU models via processor's power management model-specific registers (MSRs). In automatic management mode it continuously monitors the CPU usage level and dynamically adjusts the CPU frequency, throttle and/or voltage level as needed, realizing the "Performance on Demand" concept.

best of all, it free!

 

Hm, as far as I know Prescott cpus have only thermal throttling. No speed step technology in P4 notebooks, this is why you cannot undervolt. I just can't resist it: you've got a frying pan for a notebook How are your temps?

Take a look here. You can control the thermal throttling with RMCLock - from 100% down to 12.5%. Just checked it on my office desktop. I was able to get it down to 700mhz but Windows was barely moving. Hope this brings down your temps...

Woah, no SpeedStep?! I thought this feature was standard for Intel CPUs. I never knew about that. And wrt your question, I don't have a thermal monitor. In PC Wizard it reports a general temperature of 67C which I understand is terrible. But it could be worse, considering that HP used to make pavilions with 3.6GHz P4s. Those were probably extremely unstable.

Thanks alot for the suggestions, people.

 

You sure P4s dont have speedstep? I thought they had dynamic switching which was the same but under a different name. My old PIII-M ULV had dynamic switching. Try heading into the bios. There may be options for dynamic switching, high, low and variable (dynamic) which is what you would want. Also try installing Notebook Hardware Control, it should be able to regulate dynamic switching if you have it.

 

Don't forget, not all P4's are Prescott's either. Just cuz Prescott core P4's don't support throttling, doesn't mean the older Northwood or Willamette core ones might not.

 

According to PC Wizard, this CPU has EST - Enhanced SpeedStep Technology. This Pentium 4 was one of the "higher-end" ones; it has all of the listed features, except for 64-bit capabilities and a two other minor technologies. I know that it jumps from 1.84GHz all the way to 3.07GHz (slightly faster than stock) and I've even used NHC to clock it down to 300MHz, where XP slowed to a crawl. Anyway, RMClock looks good. Thanks people.

 

BC135, what is the number of your Prescott. Only 6x0 have EIST but if so it must also have EM64T, which is Intel's 64-bit implementation. My Prescott lacks any multiplier-changing features; it's older obviously.

 

I have the 532 variant. I don't think any of the mobile P4s have 64-bit architecture, just the Extreme Editions.

 

Obviously you have the Mobile Pentium 4 532. I am talking about desktop Prescot 5xx and 6xx series. As far as I know, HP used to put desktop P4 in zx5000; that was my assumption.
