Hi,

Hmmm ok thanks.

Slasher

Might your be unsupported....see NOTE:

Current release of RMClock utility implements the CPU frequency, CPU load and throttling level determination on the following processor models:

• AMD K7 (Athlon/XP/MP, Duron, Sempron) and K8 (Athlon 64/FX/X2, Opteron, Dual-Core Opteron, Sempron, Turion 64/X2) family processors.
• Intel Pentium II/Celeron, Pentium III/Celeron, Pentium M/Celeron M, Pentium 4/Celeron (Northwood and Prescott cores), Pentium 4 Extreme Edition (Gallatin and Prescott cores), Xeon (Prestonia, Nocona, Cranford, Irwindale, Potomac, Paxville and Dempsey cores), Pentium D and Pentium Extreme Edition (Smithfield, Presler and Cedar Mill cores), Core Solo/Celeron M/Core Duo (Yonah core) and Core 2 Duo/Core 2 Quad/Core 2 Extreme/Xeon (Conroe/Allendale, Merom, Woodcrest, Kentsfield/Clovertown cores). "

Dynamic P-state transitions are supported on:

• AMD Athlon 64/FX/X2, Sempron, Turion 64/X2, mobile Athlon 64, Opteron and Dual-Core Opteron featuring AMD Cool`n'Quiet(tm) technology.
• Mobile or Low-Power Desktop AMD Athlon XP featuring AMD PowerNow!(tm) technology.
• Intel Pentium M, Intel Core Solo and Core Duo, Intel Core 2 Duo, Core 2 Quad and Core 2 Extreme, Intel Xeon (Woodcrest and Clovertown cores) featuring Enhanced Intel(R) SpeedStep(tm) technology (EIST).
• Intel Pentium 4 600 series (Prescott N0 core), Intel Xeon (Nocona, Cranford, Irwindale, Potomac, Paxville and Dempsey cores), Intel Pentium D 800/900 series (Presler core), Intel Pentium Extreme Edition (Smithfield, Presler and Cedar Mill cores) featuring Enhanced Intel(R) SpeedStep(tm) technology (also known as Demand-Based Switching).

NOTE: Intel(R) SpeedStep(tm) technology and the "old" vision of Enhanced Intel(R) SpeedStep(tm) technology found in mobile Pentium III-M and mobile Pentium 4 processors are not supported.




Dynamic on-demand clock modulation adjustment is supported on:

• Intel Pentium M/Celeron M, Intel Pentium 4/Pentium 4 Extreme Edition/Celeron, Intel Xeon, Intel Pentium D/Pentium Extreme Edition, Intel Core Solo/Core Duo, Intel Core 2 Duo/Quad/Extreme featuring On-Demand Clock Modulation (ODCM).

RMClock utility will run on unsupported CPU models, however, in this case, most of its functionality will not be available.

Hi,

So if I have a Northwood P4 which I think I do, then Dynamic P-State won't work right?

Do you know any alternatives to RMClock to undervolt my processor?

Slasher

Have look here, might helps you a little:

Hi,

Thanks for the link, but it didn't help at all. Sorry. What next?

Slasher

That's mean you won't be able to undervolt...you need a cooler!
