Step by step guide - Overclocking ATI and undervolting Core 2 Duo in Vista (+results

Hej Ivan
Being reading this thread with great pleasure.
Have been able to reduce my Zepto 6625 from 89-90C to 75-77C.
Couldnt get the voltage lower than 1.025V but am very pleased as my fan normal kicks in just after 80C- so alls very quiet at the western front .

Did notice one odd thing: when ticking the multipliers found i also had a 12x (processor is t7500) and actually had to reduce this one also to get the effect on the 11x multiplier (otherwise it just tested with "normal" voltage of 1.250V), however, after the computer shutdown when i tried to lower the votage to 1.0125 and restarted the 12x multipler diappeared.
Am wondering if my processor actually is a t7700?

To you guys who are unable to get RMClock to work on Vista x64, found following instructions on another thread:

Install RMClock anywhere on your PC expect program folder.
Make a new folder on your pc- again anywhere but in the program folder.
Paste following files into the folder:
Atsiv.exe- workaround for Vistas signature problem
RMClock.exe
RTCore64.sys

With notepad make following bat file:
Atsiv -u RTCore.sys
Atsiv -f TCore64.sys
start "RMClock" "D:\rmclock\RMClock.exe"- this is my folder.

Save it i.e RMClock-startup.bat

Make a shortcut to desktop and move it to your startup folder and RMClock will start automatically with windows.

Will attached Atsiv if anybody wants as unable to get it from the company who made it due to a dispute with M$- google and read about it on their webpage.

 

I'm using NHC, and I have a problem with the "Voltage" tab on it in that the default multipliers and voltages don't show up, and so I do not have any options in the drop-down menus. I've clicked on the help (question mark) icon, which is what the website recommended, but that didn't do anything. Also, RMclock doesn't do anything, and the P-states checkbox in the "Performance on Demand" tab doesn't remain checked. I would appreciate the help.

 

Well if you have a Santa Rosa processor the voltages won't show up in NHC. Could you provide screen shots of your RMclock Performance Tab? Are you making sure that you hit apply after making your selections?

I already uninstalled RMclock, which was a bit confusing since it came with an installer but didn't come with an uninstaller. For some reason, uninstalling RMclock screwed up my Vista control panel (it opened for a second then closed itself). I somehow got my control panel back up, but now I'm really reluctant about reinstalling RMclock. All I really remember about the "Performance on Demand" tab is that it had only one checkmark for "Use P-states" and it became unchcked as soon as I removed my mouse. If it helps, I have a T7500, and I'm running Vista 32-bit.

 

I cant get NHC and RightMark CPU Clock to work on my laptop. It get the message that it was unable to install driver. Im using Vista Ultimate 64-bit by the way, is that an issue?

 

Hi norup,

I think it was some kind of a bug or something. I wouldn't know the answer. Sometimes some multipliers show up twice for example, sometimes it shows 11 and 12. Try some CPU id program and see what CPU you really have. What does it say when you start the stress test? If it says 11x that it is the highest multiplier and thus t7500 if I am not mistaken.

Thanks for the RM Clock - Vista 64 bit - I will link it into the original post.

Cheers,

Ivan

 

I have a similar problem to MikerSoft..i got a santa rosa processor,and at first i tried NHC but the voltages didn't show up as well..

But then i used RMClock...thing is in the CPU info part it says minimal multiplier 6x @ 0.937 V and maximum 11x @ 1.30 V

Problem is...in the performance on demand part all the multipliers read 1.300V,i don't know if they actually all use 1.300 V or the program isn't calibrated right??
And i'm not sure if i am to undervolt,what voltage should i set each multiplier to,since i don't even know the default was...

Anyone has any idea how to solve this problem?

 

Hm. Perhaps RM clock or NHC start better supporting of Santa rosa .

 

HELP!!!!

i read through the forums and tried to undervolt but now, windows is not even restarting.

setup is

XPS 1530

I used RMclock and followed the instructions posted.

After i ran Orthos, it gave me a blue screen and then my system just shut down.

Currently, my windows vista is not even starting up.

Can anyone help me ?

thanks

 

Hi all!

I have an XPS m1330 with a 2.0 GHz T7250 cpu (santa rosa). I have tried to undervolt the cpu using RMclock 2.30.0 update1.

However, I have some problems:

1.
If I first run a benchmark of the cpu and get a benchmark score, this score is cut in half if I start RMclock in "no management" mode and re-run the benchmark. If I have understood things correctly, RMclock shouldn't alter the cpu settings as long as the current setting in RMclock is "no management". So why is the benchmark result reduced?
The funny thing is that if I close RMclock and re-run the benchmark, the score is still only 50% of the score I had prior to running RMclock....i.e the cpu settings do not revert to default settings after exiting RMclock. If I reboot the computer, the benchmark score is back to normal again. Is this the way it should be?

2.
Every time I benchmark the cpu whilst running RMclock, the cpu won't go higher than 1.2 GHz if Thermal Monitor 2 is enabled.
Now,If I disable thermal monitor 2, my cpu runs at 2.0 GHz......BUT...max cpu load is now only around 57%. I have tried a lot of different settings in RMclock, but so far I have not managed to get my cpu load up to 100% at 2.0 GHz.

Is it my santa rosa cpu that is incompatible with RMclock, or do you guys have any ideas how to solve the issues described?

 

Hi,

I think some of the Vista files were damaged (not closed or rewritten) when your comp went BSOD. Try with Vista DVD - it should repair your Windows. Remove RMClock from startup.

I hope you will fix it.

Ivan

 

It seems that RMClock has some issues with SantaRosa. I had many issues with RMClock and that was one of the main reasons I was using NHC. Now RMClock works ok with my system (not SantaRosa) and I don't use NHC anymore.

I hope you will find some way to undervolt.

Cheers,

Ivan

 

Hi, Ivan!

Ok, so I guess I have to wait for an updated version of either RMclock or NHC then to be able to undervolt my santa rosa cpu.

Thanks for your reply

PS!
Are RMclock and NHC the only alternatives there are when it comes to undervolting, or are there other types of software out there that may work on santa rosa cpu's?

 

Actually I think that the latest RMClock beta version works with Santa Rosa. I read it somewhere. Try RMClock site or Google.

Cheers,

Ivan

 

Great work. But i wonder why Intel/AMD processors dont come undervolted by their manufacturers?

Why my T7300 runs at 89 C at 1.300 V, instead of 1.075 V at 73 C(max)?

There is something we should be aware of?

 

Hi pavilion,

Thanks. I am glad you liked it.

It is the stability they are aiming for. Even the same CPU model cannot be undervolted the same way. Manufacturers actually set voltages higher so they can guarantee very high stability at expense of power consuption and heat. You wouldn't care too much with desktops, but in notebooks undervolting makes sense. If you have the same stability and speed, but lower temp, that sounds very good to me.

Cheers,

Ivan

 

Neither NHC or RMClock seems to work with my m1330. Is it cause of the Penryn CPU?

 

also interested bout that.. does anyone know how effective undervolting would be with penryns?

 

RMclock v2.30.1 works fine with Santa Rosa T7500 on both 32bit and 64bit (with work arounds of course). Never had any issues with it

I believe RMclock doesnt have full Penryn CPU support yet.

 

Thanks flipfire - 2.30.1 you say? Ok guys that is what you need for Santa Rosa and 64bit.

Ivan

 

Hi, first congratulations and thanks for this great guide.

I was just wondering if you could help me out a bit with the OC.

I have a ATI Mobility Radeon HD 2600 with 8.2 Catalyst and drivers, ATI Tray Tools is 1.3.6.1067. The stock spees my laptop came are: core 500MHz and memory 600MHz.

The problem is the following:

1. When i enter the OC section in ATT on the tab current GPU and Mem show 0.00 and current bios for the same items show the stock speeds.

2. When i apply OC by moving the sliders i run the tests and everything seems fine (though is weird that i can push sliders all the way right, run tests and no artifacts).

3. After putting about 10MHz more on each component i check include clocks in profile, then go to save the profile but it always saves it like this:
Name *0.00:0.00 C. After i hit the ok the window exits and push the sliders all the way back to 0 (according to the programs that's the defaults).

4. When i reopen the window to load profile the sliders are at 0, like no tweaking ever happened.

Any ideas what could be causing this? BTW the laptop is brand new and the only things i have changed are the display drivers and catalyst, OS is the stock one Windows Vista Home Premium 32bit.

Agains thanks for the guide and your time.

 

Well, I've read this whole thread and even with the latest version of RMClock that was released on 2/29/08 (version 2.35), RMClock still won't work on Vista 64 Bit.

The Atvis tool has been blocked by Vista through extreme measures so I can't go that route either.

Has anyone figured out a way to get RMClock to work on Vista 64 bit?

Thanks.

 

i got rmclock working with x64, used this file to load the atvis/driver file, works great

Code:

'Initialise vars
FstCmd = """c:\program files (x86)\RMClock\Atsiv.exe"" -u ""c:\program files (x86)\RMClock\RTCore64.sys"""
ScndCMD = """c:\program files (x86)\RMClock\Atsiv.exe"" -f ""c:\program files (x86)\RMClock\RTCore64.sys"""
Program = """c:\program files (x86)\RMClock\RMClock.exe"""

'Initialise objects
Set WshShell = WScript.CreateObject("WScript.Shell")

Return = WshShell.Run(FstCmd, 1, true)
Return = WshShell.Run(ScndCMD, 1, true)
Return = WshShell.Run(Program, 1, true)

got it from here http://forum.notebookreview.com/showthread.php?t=220543

 

I have been going through this place to get an idea of what I wanted to do to my laptop when I got it and have found many helpful parts. Well I just got my new system:

HP Pavilion dv6700t series (custom)
Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz
NVIDIA GeForce 8400M GS
OCZ 4096 MB DDR2-SDRAM
HD 250GB
Intel(R) Wireless WiFi Link 4965AGN with Bluetooth
Windows Vista Home 32-bit

and I have been having a little trouble. I already know that I can not use all the ram that I have because of the 32-bit Vista, but I wanted more ram and was not willing to pay HP for it so I bought it myself off Newegg. The thing is, because the processor is so new it seems to keep a lot of the tricks I have seen from working. I know as of right now I cannot undervolt the processor and I tried to get Clockgen to get more out of the ram. The ram is not PC-5300, silly me bought PC-6400 because of the higher bus. I now know that my ram is going to be underclocked, but I would like to see about pushing it up. I would also like to see about pushing the GPU a little. I would like to know if anyone has any information that may help me in this. I have gone through much of the information on the post around here, but I did not find any real nuggets of gold. So if anyone has anything I would really be thankful.

If I exit RMCLock, will I still have my custom voltages?

 

As far as I have read you have to have it running to keep your custom settings.

 

Yes you will need RMclock on for the undervolt to be in effect

 

Quick question about RMClock v. 2.35. I tried using 2.30 but it didn't recognize my processor (Penryn).

When I change my max voltage down for testing, the CPU info tab still displays the default voltage as the maximal value (1.1375 on Index 12 and 1.225 on Index 13). Even though I've gone through Blackbird's post multiple times to make sure I'm not missing something, apparently something's not jiving unless I'm missing something else.

In this thread I've got a screen of my settings. Not trying to cross-post. Just wanting to know if it's a Penryn and 2.35 issue or is this normal not to show the maximal value you've entered and applied to the settings on the cpu info tab? In other words the maximal value isn't changing on the CPU Info tab no matter what I change my voltage to.

 

im having the same problem..

 

I'm trying to run RMClock on my AMD Turion X2 TL-56. I went into the Performance on Demand, activated PST and then checked all of the Index's. When I click on apply, my screen starts showing artifacts on the right side. When I disabled PST, they went away. I know my processor supports PST so what am I doing wrong???

 

d94, have you turned off IDA? That did the trick on mine and now RMClock is working, showing the voltages I'm lowering it to for testing. Instead of checking the IDA index, leave it unchecked in Performance on Demand and in the main Profiles tab of RMClock if you want to give it a try.

Here's a thread on it at the RMClock forums that reports it as a bug in the current version of RMClock:

http://forum.rightmark.org/topic.cgi?id=6:1483

 

Thanks for the great guides.

To the people who asked about running RMClock on Vista 64, one easy way to get it to run is to simply press F8 before Vista boots like you are trying to boot into safe mode. You will then be presented with a list of various ways to boot Vista. The last one on the list is "Disable driver signature enforcement". Select that one and then Vista will boot with driver signature enforcement disabled and you will be able to run RMClock fine. The first time you try to run it Vista will still pop up a warning but just dismiss that and you won't see it again. The only problem is you will have to use this F8 boot procedure every time you restart Vista. That isn't a big problem for me because I mostly let Vista sleep and don't restart that often. It's definitely worth pressing F8 at boot once in a while to be able to run RMClock (and this work around also allows you to run PeerGuardian2 on Vista x64 btw).

 

I think they have blocked this on x64 SP1. There was another work around before this one and it got blocked too

There is an even better work around, its a program called Astiv. It bypasses the driver checking. Great stuff for x64

 

NOW , my old laptop has a serious annoying problem .....
Every time i play a game the laptop temperature increased and the performance decreased too much (THUS I CANT PLAY) .....

so, what its the problem exactly ? as showing in the pic the hard disk temperature is too hight (sometimes it reaches 60C) , is the hard disk cause this problem or is it the CPU voltage needed to be decrease???

Is the problem related to this topic ?!!
( NOTE : I didnt overclock or change anything, just updated the Bios ).....

Toshiba M70:

Intel Processor with 2.13GHz
ATI Mobility Radeon X700
1GB of Ram

 

Anyone help me please ?!!! ​

 

Firstly NHC isnt fully compatible with Vista so try use HDTune for accurate results.

Let me know if they show the same temps

 

I am using XP , its just a theme ......
+ i feel the heat .......

 

Try reflashing back to the old BIOS, see if this is whats responsible for the abnormal temps. Does your HD have a heatsink to the fan?

Also how are your CPU temps?

 

Thanks for reply .....
but how can i know if my HD have a heatsink or not ?
as u see in the previous pic i cant measure my CPU temperature its "......" i dont know why !!!

I upload some screenshots ,,,

The Temp using HDTune:




All Info about my Satellite M70:



i hope they will be useful ....The max HD temp so far is 64C .......

 

64c is in the UNsafe ranges. I suggest backup whatever you have in that driver now. It will fail sooner or later running at those temperatures. Use HWmonitor, it will show your CPU/GPU/HDD temps

Go to the toshiba section and post your HD temp issues.

Also now you have a good excuse to get a bigger and better HD

 

i will backup my files for sure and i am buying DELL XPS M1350 in days .....

After I use HWmonitor it shows me the HDD temp only, i think my CPU doesnt have a sensor ( i am not sure ).... but thanks anyway .....

 

Hello everyone, excelent post.

My only doubt is why my minimum Voltage ID is 1.000V?,
I own a C2D T7250 Merom M0
It is by the version of RMClock? (2.30.1?)

I download the 2.35, but some options I dont know how to config.

Ok, here are my short tests for my Computer. While I was doing this, I also had soke other hidden program running that uslaly suck up 50% CPU. So I don't think this could have gone any better.

I did 2 hour on a 1.025, so now I doing 1.000V before going any lower. Before my MAX CPU was: 85C!!! Now my MAX CPU is: 67C!!!!! and I am using 0.257V less energy and still getting really good performance. I love this! My GPU has even gotten lower with its Clock of: 700 ENGINE, 800 MEM. YAY!!

Look at the picture below. Also, I have expeirenced to BSOD yet, and, I am only 15 minutes into my 30 minute test for 1.000V

 

Ok, I can confirm on my Computer, running a T5550 Intel Core 2 Duo processor, that all of the Multipliers run very stable at 0.950Volts (Which is the lowest voltage)

After I set this down to its lowest voltage of 0.950 my Procesor temperature never went beyond 55C when running Orthos for 3 hours striaght. I have added another picture of what the processor and other component temps are, along with my RMClock utlity.

I am really impressed by the results of this processor being able to go so low on power and run with maximum efficency and speed without errors. I have heard that others using a t5550, or t600 couldn't make it go any lower then 1.000V without crashing. I am not sure if these person are using "Centrino" procesor technology, because I know the desktop version of this processor do not use Centrino, thus consuming more pwoer, and, because they were not built to run off of a battery and have power efficent ways, they may not be able to drop much lower.

But I have had very good success with undervolting, and in this process, I have been able to use my battery which uslly only lasts 2 1/2 hours, not I can use it for about 5 hours.

 

Just installed ati tray tools to test for artifacts. When trying to load program, I get this message.


I have tried reinstalling numerous times. What is another program I can use to test for stability.

 

Do these temps seem safe?
Laptop Gateway m-6862
Running t5750 x12@ 1.0500V and ati 2600HD(500/600) at 570/700

 

So here we go again. Finally I tested both my favourite tools for making a notebook with Ati card cooler and faster than it used to be. This guide can be used as a reference just for ATI overclocking or Core 2 Duo undervolting. These two are not connected.

I have a HP nx9420 notebook equipped with Ati x1600 256 MB DDR2 memory and Intel T5600 Core 2 Duo at 1,83 GHz.
Based on my previous experience with x700 and Pentium M I was eager to try the same ideas with Vista and current hardware. Finally Notebook Hardware Control (beta) came out and Ati tray tools (beta) making this procedure possible in the way I prefer – clean, fast and stable.
I will be using words like:

 

Hi all, Im new to this forum, but not completley new to Oc and tweaking. I have some problems with my vostro 1500. Its gets very hot!

Its a dell vostro 1500 with t7300 2GHz duo, 2Gb ram, 8600M GT 256mb

Original settings (1.2125volt) full load: 98C - this causes RMClock to say core overheating

Undervolting (1.025volt) full load: 89C - this is working better but there is something strange, after a while in ex. a game, framerate starts to drop more and more. I think it has something to do with Throttling.

Here is part of a log from gaming:
22:08:30.433, CPU: 1, Clock: 1994.45, Throttle: 100.00, FID: 10.0, VID: 1.025, CPULoad: 93.15, OSLoad: 92.31, CoreTemp: 90.0

and then it ends like this:

22:10:54.428, CPU: 0, Clock: 1994.43, Throttle: 45.59, FID: 10.0, VID: 1.025, CPULoad: 35.83, OSLoad: 53.85, CoreTemp: 80.0

is it still overheating and just not telling me?

Best regards Eric

 

@ The undervolting guide on page 16

By default my lowest was at 1.237V AND the highest was at 1.237V!?

All my values (from 6.0X to 11.0X [5 values that is ] were all 1.237V

How can I start lowering then? Do i have to leave them all the same? and slowely change them all and run teste step by step? or can i just lower the 6.0X one alot and lower the 11.0X a little and lower step by step in between? im confused :s

Please Reply..

Thx.
