I'm interested in undervolting my lenovo t500 with a t9600 cpu - but I've read this program won't work with it do to it's multiplier? Can anyone confirm this? Are there other programs I could use?

Thanks

Edit: I'm looking into doing it with CrystalCPUID

Edit 2: I noticed Asus Mobile was having a similar issue and came across this:

http://forum.rightmark.org/topic.cgi?id=6:1770

I don't know if I trust myself to do this, but it seems to work.

My other question is - if I do use CrystalCPUID it only allows for 3 presets that the CPU will clock through. Could this possibly in the end increase average voltage use?

I'm actually in a similar boat as the poster above, with the Sager NP8662 that I'm to get shortly:
  1. Does undervolting my CPU void the warranty on my notebook?
  2. Can I undervolt an Intel Core 2 Duo P9700?

Thanks in advance,

No, it will not void your warranty. This is software based so it can always be reverted back to normal.

I don't see why you wouldn't be able to on that CPU.

P9700 should undervolt. It does have a half multiplier (10.5). See link in previous post for Registry edit to make RMClock work. While CrystalCPUID will work with half multipliers I could not get it to work at all and many others could not also.

With RMClock one little hexadecimal change and you are set. When you follow instructions of the location of the change. Where it says "0A" (10) change to "0B" (11) and your half multiplier will work.

Good luck.

Should I do a stress test for each individual multiplier or would it be safe for me to set intermediate values? I ran orthos on my minimum and max multipliers for 8 hours, both were stable.

edit:

I have 3 p-state transitions set for my performance on demand profile (4x, 8x, and 11x) yet it seems to jump from 4x to 11x, instead of going to 8x. Is there a way to set it so that it only goes to 11x when it reaches a certain load? 0-50% = 4x, 50-90% = 8x, 90-100% = 11x, etc...

I hate that RMClock doesn't recognize my Neo proc (DV2-1030US laptop). Anyone know any other good undervolting programs?
post #29 of 146
RMClock is a nifty program. I was able to undervolt my Compaq Presario C751NR to 1.0750V and my temps. drop an average of 5c on both cores.

I was never concerned about this (undervolting a laptop) because I´ve always used "company-issued" laptops! But I recently bought a netbook (1008HA) for my personal use and now I´m interested in undervolting it. So here comes the "stupid" questions!
- Does it work with the little Atom N280?
- My N280 has a VID of 1.1125 and a multi of 10x. But vcore is at 1.225. Does this mean that I could be stable at 1.1125 vcore?
Something I noticed: I entered BIOS and enabled Speedstep and disabled the thing (can´t remember the name!) that makes it show the Eee logo when it boots. Saved and exited and everything was fine. But if I restart, or put it to sleep, it automatically "resets" itself. Meaning that Speedstep doesn´t work and the Eee logo shows upon booting. Even though they´re still disabled in the BIOS! If I start it, go into BIOS, exit and save (without changing anything since it shows DISABLED), it all works fine.
- Is it safe to use Speedstep (that changes multi) together with ASUS "Super Hybrid Engine" (that changes FSB)?
- Can I use Speedstep, Super Hybrid Engine and still undervolt it?

Sorry for the long post, but I guess it´s all related to the thread. Thanks a lot in advance!
