The "Undervolting" Guide

[deputc26]

Okay thanks to a registry tweak I was able to unlock all the VID options so now I can set as low as .7125 if I wanted to. Using this I set my SuperLFM voltage to .8500, since I figured if flipfire's T7500 goes that low, mine should too.

I don't notice a difference though... when I'm looking at the CPU info tab it shows me at 600 MHz and 6x so obviously the SuperLFM is active, but at that speed/multiplier it still shows me at .9000v. So in that regard it's not using the .8500v I configured SuperLFM to use. When I go to CPU-Z (1.41, supposed to work properly) it shows my CPU at 1197MHz and still at .9000v which leads me to believe perhaps RMClock is saying SuperLFM is active but it really isn't. Any thoughts on this?

Whoooa!? what reg. tweak? I've been trying to unlock all the VID options for a weak! do you mind sharing your method with me


edit: I figured it out, unfortunately intel has me locked to .95v and above.

so...whats the registry tweak? i wanna set this as low as i can go.

I dont recommend you try and tweak it any lower through the registry, this could cause big problems

lemm4: You need CPU-z v1.41 to display the correct voltages. The latest version seems to be buggy

flipfire: Thanks...

Question... what's more accurate... everest or rmclock? there's a 5degree Celcius difference between the two... everest is 5degrees higher on average...

[flipfire]

Id have to say RMclock since its a dedicated CPU utility

I suggest downloading other temp programs like HWMonitor and CoreTemp to see if its consistent. You dont have to install these programs which is very handy, you can just run them off a .exe

[lemm4]

Thanks.

In RMclock.. I get 32Celc idle...
In HW... I get 37Celc idle...

What's more accurate?

[flipfire]

37c idle sounds more accurate to be honest. Unless its freezing cold where you live

did you get coretemp

we did get a few cases of temp inconsistency before but that was with a T5500 processor and RMclock was the correct one. Not sure why your getting it on a T9500

[lemm4]

Yup Coretemp reads about 38c.... then again... also reads my penryn t9300 as a wolfdale xeon 5190 lol...

Excellent guide. For some unimaginable reason my 1.60ghz Core Duo T2050 was set at 1.2625v for all multipliers 6 through 12, which is terrible. At that voltage the cores maxed out at 76C and 79C, which are now 67C and 69C @ a stable 1.000v. If only I could set my 800mhz voltage lower than the minimum of .95v...

go into your rmclock folder there's a registry file called "tweaks" or something, run it.

go-->Start-->run-->regedit -->from the menu bar select "find" search for "unlockvid" when you find it, open it, and change the value to 1. restart rmclock and voltages down to .715 will appear.

NOTE: if your voltages were detected correctly you won't be able to go lower than you were
