Latitude E6400 Owner's Lounge, Part 2

It's possible that Windows 10 doesn't let RMClock work properly - those temperatures are very low if being read correctly. What does HWiNFO > Sensors show?

I don't know how well ThrottleStop works with older hardware but it would be work trying it.

Thanks John.

RMClock (and TaskManager>Performance) and HWiNFO show different readings for Temps; ~5C more in the latter. Screenshot:


I have also enabled SuperLFM (multiplier 6.0x) in RMClock and for my 'Power Saving' profile, it is the only active multiplier. Here, RMClock (and TaskManager) shows the cores dropping down to ~800Mhz, but HWiNFO shows ~1600Mhz. Screenshot:

Aren't they using the same sensors? Why the different readings? I would assume RMClock is correct because the readings are approximately the same as those in Task Manager... yes?

Finally, in HWiNFO > SMART... why does the 'Drive Warning' sensor show Yes? What exactly is the warning about? Is my drive about to fail?

PS: I've tired ThrottleStop; I prefer RMClock. I'll try the former again if I am not able to satisfactorily continue with RMClock.

 

@slander - I do not think that RM Clock can fix Chipset Clock Modulation throttling. The other problem with RM Clock is that it does not support 45nm CPUs that use half multipliers. The P8400 has a default multiplier of 8.5 but it also uses an IDA multiplier of 9.0 so this multiplier limitation might not be a problem for you.

Some monitoring software does not correctly detect when these CPUs are using SLFM mode. Some monitoring software reports that the multiplier is decreasing when inside the CPU, it is actually the Front Side Bus MHz that drops in half. Some monitoring software does not report anything when the CPU enters SLFM mode. ThrottleStop should report this correctly.

If you want to stick with RM Clock that is OK but you might have to run it along side ThrottleStop to get rid of the throttling issue. If you want to do this, do not use the ThrottleStop Set Multiplier or voltage adjustment features. Leave that to RM Clock.

A slow CPU used to be a great way to save power until the low power C States were developed. Holding a CPU to a low speed will reduce performance but it might not reduce power consumption as much as you think. A fast CPU that can get work done quickly which allows the CPU cores to spend a bigger percentage of time in the low power C States.

Has anyone been able to get the fingerprint reader to work on Windows 10 Anniversary update?

I had the finger print reader working perfectly on Windows 10 previously using some updated drivers.

EDIT: found my own answer, finger print reader working well again!
installed the control vault drivers for e6430 here:
