The "Undervolting" Guide

IF i get the BSOD, would i have to do a system recovery?

 

CPUClock couldn't detect my CPU. I'm using Turion X2 RM-70 with 780G chipset. Is there anything wrong?

 

1st is RMClock. 2nd, RMClock doesn't support the new AMD CPUs (neither will it support the upcoming Intel ones, based on this). You need to wait for the new version of NHC to come out (apparently it's being worked on).

 

No. You won't need to recover, what will likely happen though is it will say Windows was not shut down properly... you can just ignore it and start normally.

 

After i installed the 64bit driver for RMclock, it still says the wrong processor and whatnot. Anything i can do to fix this?

 

Ok this is weird.

Why is it that my cpu temps are higher when gaming? i mean its like nothing changed at all after undervolting.
Before while gaming i used to get 74C ish as peak before i undervolted, and after i ran the stress test AFTER i undervolted i got around 62 as peak, now when i play games the temp goes to 71..
this is like nothing barely changed...

 

shinakuma, how did you get your RMclock to detect your chip?

 

i used the mobile option, im pretty sure i did it all right.
Undervolted from 1.250 to 1.0250 on the 12.0x multiplier

Weird thing is, for the past 2 days since i undervolted, my gaming temps were at peak 64, now its gone up to 70-72 again, ***.

 

Could be GPU heat making the CPU hotter.

 

I still cant get RMclock to detect my processor. t9400, dv5t

 

RMclock wont detect the Intel P7350 in my U330.

 

Can you see the voltage controls at all?

RMclock is outdated so it might not be able to recognize your newer CPU's fully but you will still be able to undervolt aslong as you see the mutliplier/voltages in the profile page.

 

Yes, I do. I'm also in the process of undervolting it right now! thanks!

 

Like he said, gpu could make it increase. Also, be sure it is always undervolted. Maybe you go on battery mode and settings dont change back on someting like that

 

Does it matter if my 8.0x has a higher voltage than my 9.0x?

 

Tick "Auto-Adjust intermediate multiplier" and move the 9x voltage again. Your voltages should be adjusted accordingly now.

 

Thank you! I know i can maintain atleast 10c cooler, but should i try for more?

 

Hi guys:

I currently have mi 1330 undervolted with RMClock. Have tested stability thoroughtly with Orthos (24 hour sessions) with no errors whatsoever.

However, when i listen to any kind of music the sound tends to skip a lot, making it very uncomfortable. Closing RMClock solves the issue immediately (no more music skipping)

I've got a T7250, 2GB ram, 200gb 7200 RPM

What is going?? Could it be a problem with enabling SuperLFM with a 6x multiplier?

My voltages are the following for "performance on-demand":

index voltage
0 0.85v
1 0.85v
2 0.875v
3 0.9125v
4 0.9375v
5 0.9750v

IDA is disabled as i've heard it causes a lot of issues and it's not worth it....

Thanks

 

hi, when using superlfm the rmclock icon (the thing that looks like a cogg) goes half pink and half blue can anyone explain what this means please

thanks

 

Sure.. why not?

Is this with iTunes?

1)Try disabling SuperLFM.
2)Go to Vista Power profiles > Additional Power Settings > Choose RMclock Power Management as the profile
3)Is your thermal monitor 1 and 2 enabled?

Yes that just means SLFM is enabled.

 

Ok I am very confused. I am running RMClock witht he 64 bit drivers. WHile it doesnt recognize my CPU (HP dv7t with a P8400) I can adjust the voltages. I have superLFM and three multipliers of 6x, 7x, and 8x. Now for the most part when I look at rmclock it is running my voltages correctly
.9v for superLFm with a 6x and .95v for the rest (I havent dropped them yet..havent had time...they started at1.2 so not bad).

Heres the issue though. I hover my mouse on rmclock sometimes and it shows my 6,7,or 8x multiplier with a completely different voltage than what they are set at?? How is this...is it because the CPU isn't fully supported?

Thanks...first time doing this.

 

No, this is not with itunes, it is with winamp... also happens with WMP so i think the player has nothing to do with this.

Both thermal monitors (1&2) are disabled.

I have upped the multiplier to 7x for SuperLFM and the skipping seems to have dissapeared... this obviously requires further testing

 

I i have vista 64bit too, (dv5t) but i just went ahead of undervolted it. Now, i am ready pretty low temps. I get under 40 degrees C while im surfing the web+ chatting.

 

Out of interest, does Notebook Hardware Control work with the newer processors (I have P9500)? I ask because of the multiplier issue.... does this have the same problem or would NHC be able to recognise the 9.5x?

Also, have some good undervolts been reached with the P9500? What should I be aiming for?

Cheers.

 

Yeah I undervolted mine and I do have lower temps, however the voltage still fluctuates sometimes when it s changing proc speeds.

Sakor from what I read on NHC's site they are coming out with a newer version to support the newer procs, however it is 32 bit only.

 

does anyone know why vista reports that the speed of my processor is the full 2.4ghz when rmclock says its on superlfm and should be running at 0.8.

to get vista to tell me processor speed i am right clicking comper and then going to properties.

thanks

 

NHC is horribly out of date. The author has been promising a new version for a year and a half and has missed every single tentative release time frame, including the latest one in which he said it would be released in "late september"... October 3rd now and another date missed. I doubt we will ever see a new NHC release. The author's own forum mod believes it won't happen.

 

Is there anywhere on the Planet that one could look for a utility besides NHC for the things that RMClock won't do like fan, screen, sleep, acpi etc??
(Unless you're one of the chosen few that can write their own NHC modules)
Any "guns-for-hire" that will cook up modules that will work with existing NHC?
Are notebook owners too stupid to be trusted with normal desktop adv. BIOS features for these hardware functions.

 

It's an interesting issue. With heat and battery life being a real concern these days you would think that these projects would not all be dying off, but they appear to be doing so anyway. Mac users face a similar situation, though their only app for undervolting is still being updated. It's called Coolbook.

I do not know of another app that will handle all of the things you mention. If you run across one though, let me know.

 

Consider using words that are more simplistic for the average user.

 

Over my head but want to learn more. Thanks for the info.

 

Great information...keep it coming.

 

Hi Everyone:

Is there any way to *REALLY* decrease the voltage to a value below the lowest voltage that RMClock provides for SuperLFM ???

I've read through this long thread and some people ask about it, then some seem to be answering, but none of them actually works....

So is there a way to set it to a lower value....? Maybe manually change the file where RMClock saves its settings (which I have no idea where it is)?

 

Heard that RMClock does not fully support the new Centrino 2 platform yet, so changing the voltages and the multiples will not work.....what else can be done besides these things on the new Centrino (Montevina) platform?

 

No not possible without doing rocket science with the VID pin mod. Intel has locked the voltages.

You can change the voltage and multipliers on the second gen penryns. Though it might downclock for specific processors if they have a half multiplier. RMclock cannot recognize these.

What CPU do you have?

 

I don't have much experience and i want to undervolt my notebook too (zepto nox). i got a Intel® Core 2 Duo P8600 2,4 Ghz FSB=1066 Mhz processor... that's centrino 2 right? Can i undervolt this one to?

 

Hi.

To run my processor P8400 at full i need a multiplier of 8.5 , but i can only find 8 in RMCLOCK, how can i do this?

Thanks

John.

 

i just read that undervolting is possible on new AMD CPU's (turion ultra's) using AMD fusion and Overdrive. anyone into it? any explanations?

 

Yes you can. John Ratsey managed to undervolt his P8600 to about 1.137v

You cant unfortunately, RMclock cannot recognize half multipliers. If it could recognize the IDA multiplier (like in the first gen penryns) then it will also use the half multiplier.

 

I have the Intel Core 2 Duo P7350 Processor (2.0 GHz, 1066MHz FSB, 3MB L2 Cache)....Thank you for your expertise in this area

 

yep, imanaged to get the 9x to 0.9750, 8x to 0.9250 and the rest to as low as rmclock would let me

 

Nice . When i got my laptop i'm going to undervolt it, thanks for info all!

 

Hey all, I would search the topic but it isn't working for some reason. Anyways, anyone have a working link for the 64-bit vista RMclock? The link in the beginning doesn't work. Thanks

 

I believe the P7350 has a half multiplier (8.5?) and RMclock cannot recongnize so it will downclock by like 100mhz

Are you talking about the signed x64 driver link or the rmclock link? cause it seems to work fine...

 

It doesn't apply the voltages and doesn't detect my desktop cpu right, it thinks it's a penryn while it's a wolfdale (thanks CPU-Z). The voltages are also way too high (checked the real vid's with HwMonitor 64-bit). The linked RTcore64.sys does NOT work on Vista 64 and 45nm cpus...

Where is an update to rmclock....?

 

on my 6864FX ive dropped the 12.0x to .9750v and 11.0x - 6.0x ive dropped them all to .9500v. i dont get the BSOD or any warnings from Orthos but is it safe to have all of them at the same voltage except the highest one?

 

It's perfectly safe, you just happen to have a really good CPU.

 

Works fine for my penryn (45nm) and 64 bit vista.

 

Does the P8400 have a half multiplier?

 

hey just a quick question what would happen if i had all the FID's checked and the last one 12.0x unchecked.. would that mess up the computer? bad performance? thanks
