If you can't overclock your CPU try this:

[Guest Robbo]

I've been trying for ages to overclock the CPU in my Dell M1530 (T7250 CPU). SetFSB didn't work which is the most common method for overclocking stubborn laptops. I've found a program which doesn't seem totally common knowledge on the net, that allows for limited overclocking of the CPU. Basically any CPU which has IDA mode can benefit from what I will show you (That's any Core 2 Duo CPU basically).

Okay, so to start what is IDA mode. IDA mode is something that your Core 2 Duo does without you even knowing. If the load on the CPU is low, then the CPU will overclock just ONE of it's 2 cores to give more performance. Now, what I will show you will enable you to force your CPU to run at IDA frequency levels on BOTH of your cores for 100% of the time. So, for my T7250 which is 2Ghz at 100% load, using this program I will show you enables it to now run at 2.2Ghz for 100% of the time when at 100% load. It's been coined the 'Dual IDA mode' (google that if you want to know more about it outside of this thread).

OK, so the program is called ThrottleStop, which is a free program that seems to have been designed by an independant enthusiast. Not only will it give you 'Dual IDA' overclocking, it will also enable you to undervolt your CPU, thereby running using less power & running cooler. => Double Bonus!

You can find the ThrottleStop program at the following link in the first post of the forum on that link (just click on the ThrottleStop link when you get to the forum in the following link):

http://forum.notebookreview.com/acer/452692-acer-throttlestop-thread.html

Also, in that link above (also in the first post), you will find a link to click on for instructions on how to use the program.

Now for the enabling of the overclocking by using ThrottleStop, follow the instructions located in the first post of the following link:

http://forum.notebookreview.com/windows-os-software/477704-how-enable-intel-dynamic-acceleration-ida-both-cores-core-2-duo.html

This all sounds a little bit complicated, but it's not really if you take the time to read the first posts at each of the links I've given you above.

Well, good luck with your 'overclocking' of you CPU, and post back to let me & everyone else know how you got on. As a word or warning if you're new to overclocking and/or undervolting then please research around this topic before you try this. Above all, monitor your temperatures using free monitoring software such as CPUID Hardware Monitor to make sure temperatures don't exceed safe limits.

Bonus 10% performance, plus the ability to undervolt in a small free program can't be bad!!

Replying to your own thread is poor form I know, but I can't edit my previous post I think, and I wanted to add to it.

I want to expand upon the benefits of this program and what I have achieved with it. I mentioned before that you could undervolt as well as 'overclock' (well, you can enable Dual IDA 24/7 at 100% core load, which isn't possible without this program - ThrottleStop). So for the undervolting, just wanted to let you know what I have achieved with my Dell M1530 with the help of this program:

Before CPU at 100% load = 1995 MHz

After ThrottleStop 'Dual IDA Mod' = 2195MHz

Before (stock) voltage on CPU (IDA mode) = 1.275V

Now (using ThrottleStop to undervolt) = 1.0375V with Dual IDA invoked.

By undervolting CPU, my CPU temperatures have dropped by about 15 degrees centigrade. Also, by undervolting CPU, (because my GPU shares the same heat pipe), I am able to overclock my GPU to insane proportions without it overheating. My GPU is now overclocked from stock values of 475 core / 950 shader / 700 memory to 700 core / 1700 shader (insane!) / 1000 memory (this is the 8600M GT GDDR3 version). Basically if you make your CPU use less power by undervolting, then your system could have more room for GPU overclocking without GPU temperatures going over acceptable limits (I would say over 90 degrees centigrade on your GPU is not advisable). With this setup, my GPU is at 85 degrees full load on GPU & CPU (Furmark & P95).

Apologies for replying to my own thread, but couldn't add this extra info otherwise. As a result of all these modifications (CPU undervolting & overclocking, as well as GPU overclocking), my 3DMark06 benchmark at 1280x800 resolution has increased from a stock 4527 to 7029 when overclocked. A 55% overall increase in system performance in terms of games is not to be sniffed at! None of this would have been possible without overclocking CPU (& undervolting at same time), and wouldn't have been possible without overclocking GPU. Just keep an eye on your temperatures! I reckon I've given my laptop a few more years of NOT being obsolute - BONUS! You can too, just be careful with temperatures.

Forgot to mention previously. I'm using a notebook cooler which lower GPU temps by about 5 degrees centigrade at full load - every bit helps when you're pusing your system to the limits! Mine is the Zalman NC2000 notebook cooler which is well known & recommended, I recommend it anyhows!

Throttlestop works great on the Amilo Xi 2428, Thanks!

[omega2k1]

stupid question, but does this work with the e6600 cpu?

[omega2k1]

i can't seem to change my voltage id nor uncheck disable turbo

[Robbo the Second]

Yeah, I think it should work with that one, it's a Core 2 Duo CPU. I would think that you would be able to enable the 'Dual IDA overclocking' trick, as well as undervolt too. Give it a try, see what happens.

Hmmm, not sure why it's not working for you. Make sure you set your Power Options up correctly in Windows before you try this program. What you want to do in your Power Options is set CPU minimum speed to 100%, and also set your maximum speed to 100%. If you do that, then Windows is now no longer trying to control your CPU speed, and ThrottleStop may be able to function properly thereafter.

Great! Did you manage to do the overclocking thing too? The 'Dual IDA' trick?

def. gonna try this with my T7200 later today

I have been looking for a way to OC my lappy CPU for the longest time

i've been able to downclock my cpu. i do have the dual IDA tick on. idk, maybe i missing something. maybe because its a desktop cpu inside a gaming notebook? idk

Should work on desktop Core 2 Duos too I think. Another thing you should check, check that Intel Speedstep has been disabled in your BIOS: that's a requirement to run 'Dual IDA'. Check out this link to make sure you're doing the 'Dual IDA' thing correctly, instructions are in the first post:

http://forum.notebookreview.com/windows-os-software/477704-how-enable-intel-dynamic-acceleration-ida-both-cores-core-2-duo.html

Beyond making sure you have your Power Options set correctly (as suggested in previous post to you), and disabling speedstep in BIOS, then I don't think I have any more advice for you. Perhaps it won't work on your system. Experiment with this a bit, and let me know how you get on.

i did go into my bios and disable speed-step. with that disabled, i should be able to change the voltage id right? also is 9 the max my cpu multiplier?

[StaFForD]

I cant start throttlestop because it gives me an error that says "could not open winring0.dll"

any fix for that?

I guess your max CPU multiplier will be the maximum selectable VID in ThrottleStop (whichever that one may be)! Maybe have a look on the intel website or elsewhere using Google to see what your maximum multiplier is? (It sounds like you're doing everything properly, but looks like it may not be working for you, which is a shame.). Just to let you know I'm not the author of this program, I'm just spreading the word on this, and if you want certain stuff supported by this program try getting into contact with 'Unclewebb' on the links that I have put in the opening post. Plus, he might be able to get it working for you.

I recommend you try & contact 'Unclewebb' who is the designer of the program. You might be able to get some answers from him at the links that I gave in the original post. I'm just spreading the word on this program.

P.S. To everyone else, post here if it's working for you, because that might create a more balanced picture for others who are interested in this program.

[Guest unclewebb]

IDA stands for Intel Dynamic Acceleration. Not all Core 2 mobile CPUs support this feature and some motherboards can block this feature. If you click on the Disable Turbo option in ThrottleStop and the check mark doesn't change then this feature is locked and not available.

To make this feature work you also need to be able to turn off EIST/SpeedStep in the bios. Most of the Dell laptops have this option in the bios but many other laptops do not. If you can't disable EIST then ThrottleStop will show the EIST flag grayed out and you won't be able to enable Dual IDA mode.

Once EIST is disabled, you won't be able to adjust the multiplier or the VID voltage. You need to do this first before you disable EIST.

After downloading ThrottleStop you need to unzip the folder. If you do that, ThrottleStop should be able to find the WinRing0 driver.

Where this program really shines is with the Extreme CPUS; Core 2 or Core i. This is the only free program that lets you unlock the multiplier on the Core 2 Extreme mobile CPUs like the X7800, X7900, X9000, X9100 or QX9300. One user on NBR is benching his QX9300 at 4.16 GHz. Most users are hitting 3.5 GHz to 3.6 GHz reliably with the 45nm Core 2 based CPUs. Better head to ebay before the price goes up.

And finally, this is also the only program available that lets you adjust both the turbo multipliers and the turbo TDP/TDC power settings on the Core i7-920XM and Core i7-940XM. Have a look at the world records being set over on Notebook Review forum lately and you will see one thing that they have in common. ThrottleStop. :)

i was going threw an older post for enabling ida and i wanted to post some things. pic 1 is my MSR 0x199 and pic 2 is MSR 0xCE. i have the asus c90s gaming notebook with the e6600 cpu.

Edited August 23, 2010 by omega2k1

[Guest unclewebb]

An Intel E6600 desktop CPU has a maximum multiplier of 9.0 and does not support Intel Dynamic Acceleration so you can't get IDA or Dual IDA to work on a CPU that does not support this feature. MSR 0xCE confirms that. The EDX register in that MSR confirms that your maximum multiplier is 9.0

now that just sux,lol

Many thanks for the tip! Here I thought I was going to have to trash my laptop as it kept overheating (which it didn't used to do), but with this program I was able to lower the voltage from 1.225V to 1.000V, lowering the temperature under full load by 20-25°C! (I can't be sure of the exact numbers since this brought the max temperature down to around 85°C, and it shuts down at 100°C) I've been testing it with two instances of CPU Burn-In, and it seems completely stable :)

Well, that's really good news that it's lowered your temperatures so it's no longer crashing. If you've not already done so, I would clean out any dust that might have built up, this is often the cause of overheating in older laptops if they've never had the dust cleaned out. (Especially now that you mention that the laptop never used to overheat, sounds like it might have dust buildup in it!).

[Ver Greeneyes]

Yeah, I'm not really sure if things gradually got worse or what, the fan still feels like it's blowing as hard as it ever did.. I've had it open a few times before, but not in a while.

[StaFForD]

finally got the program working, and now I cant turn off speedstep because i dont have the Admin password for my BIOS

time to play the email game with Dell to see if they will give it to me

[Guest unclewebb]

Did you ever find out why you were having trouble running ThrottleStop?

I always like to learn about issues like that so I can help other users.
