Wanting to disable automatic voltage control in Vista

[Wolfcastle]

I need to control just the multiplier and set the voltage on one setting only.

But if I enable EIST in BIOS and disable C1E in BIOS, the voltage still goes down when CPU is idle.

Additionally, with a Microsoft hotfix, Rightmark CPU no longer works, so I can't set multiplier/voltage profiles.

Any way to get around this issue?

It's something that should be done at the BIOS level, not the OS level. There has to be something you're not disabling in your BIOS that you should be.

Oh? I did disable it at the BIOS level, but that's actually a moot point b/c the OS CAN enable it if it wants even if it's disabled in BIOS.

On my Abit I35P-E, I am disabling in BIOS. Now, if you have an idea of what needs to be disabled in BIOS, I'm all ears. Thanks.

Thats news to me. I don't see how but I'm open to it being explained.

On my Asus P5B Deluxe where the EIST/C1E options are, I turn it all to disabled. But I don't know if that will fix your problem. My Multiplier is greyed out, must be the newer BIOS that has that disabled.

And I will give you the answer you're looking for.

In my Abit IP35-E, if I disable C1E in BIOS, I can override that and enable it in RMClock so that what was disabled in BIOS is enabled in Windows XP and Vista through RMClock.

Ok, but that would require a reboot correct?

So your gripe is that Windows Hotfix has disallowed you control over your CPU functions? I don't know if its possible, but maybe "uninstall" the Hotfix? I'm guessing its written in the registry (not positive). Good luck whichever you decide. Keep us updated, I'm interested as to why/how Windows Hotfix caused this issue and its subsequent resolution.

 

[Wolfcastle]

Windows Hotfix disabled the ability to allow RMClock and other unsigned drivers to run.

And No. Enabling C1E in RMClock does not require a reboot; I just tested it by turning it on while in Windows, and it simply started to act as if C1E is on.

I actually no longer have a gripe since I found a post in RMClock forums that showed me where a signed RMClock x64 driver is.

My original gripe was whether the voltage could be controlled by any Vista controls. But as fa as I know, it doesn't exist.

Tell us more about this. Which hotfix? That disturbs me.

It was a patch released back in the summer of 2007 that plugged a whole in Vista x64's PatchGuard kernel patch protection. It was possible to disable the signed driver requirement via a boot flag, which in turn basically nullified the kernel protection. There's nothing really disturbing about it, it's been known since the start that Vista x64 and all newer OSs will require signed drivers.
