Voltage erratic, uncontrollable, ES P9600

Using google I've found that the VID range of P9600's is .9x to 1.2. I have an ES P9600 and YES I KNOW THEY CAN BE SCREWY, but I'm going to ask here as a last shot in the dark for help.
Oddly, without any CPU controlling software it sits at the highest multiplier (10x) and at 1.2v most of the time. It flutters down to 1.075 for a second or 2 here and there.
I've tried CrystalCPUID, Throttlestop (2.8?, 3.001, 4.0) and CPUGenie, but ALL of them, when applied, do not affect the VID beyond 1.075. It will go back and forth from 1.2 to 1.075 according to CPUz and Throttlestop. The closest to success I've had is with Throttlestop, when C-states is ticked, it will maintain the specified VID for about 80% of the time. Not permanently though.

VID's @ 1.075 and lower are controlled fine by any software.

Going to guess I'm out of luck and its just a whacky ES cpu. My OC is up to 3.03 @ 1.07 so I'm confident I could reach my system's max @ 333 BLK with more voltage, so just hoping

 

On a Core 2 CPU, the highest voltage is only available when the CPU is using Intel Dynamic Acceleration (IDA) mode. That happens when one core is asleep and the other core is then able to use the highest multiplier and VID. The P9600 has a default multiplier of 10.0 and an IDA multiplier of 10.5. The maximum voltage when the multiplier is 10.0 is likely 1.075 and the maximum voltage when the CPU is using the IDA 10.5 multiplier is 1.200. During normal use, these CPUs constantly enter and exit IDA mode hundreds of times a second. That's why you will see the voltage flopping back and forth.

I think HWiNFO will show you the SLFM, LFM, HFM and IDA voltages. Each CPU is unique and can have different maximum voltages set by Intel at the factory.

If you run a single threaded benchmark like Super PI mod and you use the Task Manager to lock it to a single thread, that will allow the CPU to put the second core to sleep and the other core will spend the majority of the time in IDA mode. This is the easiest way to see IDA mode in action and ThrottleStop does a great job showing this. It accurately reports the average multiplier for each core.

On a motherboard that allows you to disable EIST, you can trick the CPU to use the IDA multiplier and voltage 100% of the time on both cores simultaneously. Only ThrottleStop lets you access this feature.

Ah haaa, I didn't think IDA mode would require 0.1025 extra voltage for half a multipler.... But it seems so.

No EIST in BIOS. Out of luck here. Thanks unclewebb!

Would CrystalCPUID's MSR Editor be able to affect Intel's Speedstep? That's what its supposed to be for, isn't it?

 

The problem is that the bios can set a lock bit on the EIST / SpeedStep bit. Once this is locked by the bios, no software can modify it. If ThrottleStop shows EIST grayed out and you can't adjust it in the bios then you are out of luck.

 

Oh poo.

Well, thank you for all your help!
