The "Undervolting" Guide

[stewie]

I'll give it a try, my XP is still a 'fresh' install.

Btw rm monitor pofile NM says system idle .8500V 8x 0.80GHz both CoreTemp and CPU-z say 1.6GHz, which one should I trust? Are there any other tools which can display the coreclock in realtime?

It's normal that RMclock shows 800MHz and CPU-Z shows 1.6GHz. For example, I've SuperLFM enabled and RMclock shows 600MHz @ 0.9000V idle clock speed, but CPU-Z shows 1.2GHz @ 1.013V instead. The RMclock monitor is pretty accurate in my experience, CPU-Z cannot show the real undervolted numbers.

I've tried searching the RM forum, I think some people are having similar issue as yours. There is another one that's a little different, his Penryn CPU will get into throttling mode and will not get out of it. Maybe there is a conflict between RMclock and certain power management software, or there is a bug in RMclock for Penryn CPUs?

This guide is amazing. I dropped my max temp to around 60 degrees! I'm running a 2.2GHz C2D and my 11x voltage is at 1.0250. My 6 and 7x are at .8500!

I have a question though. Does SuperLFM really do anything if I cant set the multiplier lower than 6?

Flipfire, if i had done this setting and i would like to undo this, what can i do?

I seem to be having problems using RMClock. I realized that no matter how high or low I set the value, the screen will turn white. And, all the icons on my desktop and even the taskbar will go array. I can click on ORTHOS, RMClock or HWMonitor. But once my mouse move to other areas, the whiteness will result. Then, I've no choice but to hard reset it.

Even when I set it to the default values (8x 0.85, 6x 0.85, 7x 0.95, 8x 1.05, 9x 1.15, 10x 1.25, 11x 1.3), the whiteness occur. And, checking 'auto-adjust intermediate states VIDs' does not change any of the values in between.

I'm running a T7300 2GHz processor. Can anyone help?

I have followed flipfire's step to do this setting. And I found that my max CPU hertz that it's run is <1999 MHz instead of <2100 MHz before. (I'm using T8100 2.1GHz)

have you tried uninstalling orthos and see if it causes the problem still?

Have you ticked ALL the multipliers?

I did not uninstall it. But I've ran ORTHOS without running RMClock, after 1 hour, no problem arose at all. No whiteness, no taskbar prob... I have even tried running RMClock alone without ORTHOS. After surfing for 30 mins or so, the screen turned white again.

So, I guess orthos is not causing the prob.

Btw, do I have to check index 0 - 5 in RMClock or only index 1-5 when testing index 5?
