How to Unlock the Core 2 Extreme Multiplier in Windows

Anyone had success on an X9100?

 

Did you right click on ThrottleStop and bring up the menu where you can select the new Unlock feature?

This should work on any Core 2 based Extreme CPU. If you have one of these and it is not being recognized then post a CPU-Z screen shot so I can have a look.

In the CPU-Z Specification box is the information that Intel has written directly into the CPU. CPU-Z reads that information and reads other information like MHz and cache size etc., and tries to figure out what CPU it really is. Sometimes it guesses wrong. That information is displayed up at the top in the Name box. All this overclocking by raising the multiplier is confusing CPU-Z. This wasn't supposed to be possible.

 

Yup. Had mine up to 13.00 x 266Mhz = 3458.1 Mhz

But I haven't pushed it further because I get a bit nervous about overclocking my laptop and I haven't got a laptop cooler as a safeguard.

 

Thanks, SFoH. Now I'm thinking of upgrading to a X9000 eventually for emulators and such.

Is there an existing pinmod or something like that to unlock the multipliers of non Extreme chips like the C2D T8100 for example? EDIT: That was a silly question after a Google search.

 

Well not too silly because it was possible to do with some AMD cpus:
The Mother Board :: View topic - Unlocking Your Athlon XP by Tulatin

My guess is that it probably is possible for intel core 2 CPUs, just intel wont share the info on how to do it...

 

Amazing program thank you for all the work. As I have an ES it is not showing the right click option to allow the multiplier to be unlocked. Here is the link to the snapshot of my cpu from CPU-z

CPU-Z Validator 3.1

 

Try going into the ThrottleStop.ini configuration file and add this.

Extreme=1

This is only for Core 2 based Extreme processors and won't work for Core i7 or regular Core 2 CPUs.

Post another CPU-Z screen shot and let me know if this works.

Your CPUID is 0x10674 so it is a mid level ES processor. Somewhere between the early ES CPUs and the retail CPU.
The final retail CPUs are CPUID 0x10676. The later the version, the less bugs.

That's also why the Specification box that CPU-Z reports does not show this as an Extreme processor. That is the information that Intel writes directly to the CPU.

Hopefully you can adjust that 15 multiplier up to about 18 or so with the help of a little extra VID voltage.

 

my validation, it locks up over multi 13

Thanks for the quick reply, I am sorry I didn't specify that I had actually added that to the .ini file and was still not getting the right click menu items. Is there another work around for this? If not I am not to stressed about it. Thank you for your time.

Throttlestop FTW. I never thought I would get my cpu to OC past 3.0 GHz because of the gateway mobo limits.

 

Your CPU is crying out for some more voltage. You will probably need to be up around 1.35 volts to get up over 3500 MHz. The VID in ThrottleStop is the requested core voltage and actual core voltage on the majority of motherboards is approximately 0.050 volts less. vdroop is part of the Intel design spec and all motherboard manufacturers are required to follow this spec.

xxERIKxx: That looks good. Somewhere around 3500 MHz seems typical if you can keep the heat at a reasonable level.

PTM487: Are you 100% sure that you entered the Extreme=1 tag correctly into the ThorttleStop.ini file? After you have done that and after you save the INI file, start up ThrottleStop and right click on it. Even my T8100 shows the Extreme menu options after I have entered the Extreme tag. There should be an option for "Unlock Max FID/VID".

Does your bios let you adjust the multiplier to a maximum of 15?

There is an email address in the About... box of ThrottleStop. Can you send me your ThrottleStop.ini file so I can have a look or upload it somewhere like MediaFire and post a link here.

There has to be something very simple that is preventing you from increasing the multiplier.

 

My x9100 is happy running 3.59 ghz (13.5x266) @ 1.3125v.

One issue, when I initially release the VID it sends my CPU to 15x266 = 3990 :/

Also is 1v the lowest that can be set on these chips?

 

Meaker: Try using the Reset CPU FID/VID menu option. When you click on Save, the latest version of ThrottleStop posted above your post should tell you the maximum FID/VID that you are about to save. If you do a Reset and then Save, that should clear out any old value that you might have accidentally saved previously. Early versions of TS didn't warn users of this and it was possible to save a high maximum value that would get used every time you started ThrottleStop. Once you have the maximum returned to default specs, then increase the multiplier one step at a time until you reach the desired maximum and then save the new value. If you accidentally go too high, you can't just go back and do a Save. You have to reset the CPU and start again.

The X9100 should support Super Low Frequency Mode (SLFM) so if this is enabled, most CPUs should go lower than 1.000 volts. The minimum is locked into the CPU which ThrottleStop reads from your CPU. Click on SLFM and see if that helps any. If the ThrottleStop VID adjuster doesn't go any lower then there probably isn't anything you can do.

 

Thanks for all the help. I actually reformatted my computer because of some driver issues and after now it seems to show up. Sorry for the weird error.

 

No problem. Now you have to do some overclocking so I can see that it works.

So far, I haven't heard of any problems that couldn't be solved.

 

The reset worked cheers.

Even after resetting it, either using normal values (stock) or setting a 6x multi, enabling SLFM crashes my comp...

 

WOOOOW! this is beautyfull, lol, Can anyone made this to a quad Q9000???? its amazing, its better if i can do something like that in my little quad!

 

Sorry etiko. You need an Extreme CPU to join this party. You'll have to do an Ebay swap and trade your Q9000 for a QX9300.

Meaker: SLFM should work in theory on your X9100 so I'm not sure why your computer crashes. I found that SLFM mode doesn't save you any measurable amount of power or reduce your core temperature at idle so you might as well leave SLFM unchecked. You're not missing out on anything important. Besides, over clocking is more fun than under clocking.

 

Yeah I don't think the laptop supports it.

My p8700 used to tick along at 266x3, but when in the new laptop 266x6 was the lowest even it would go.

 

is a good change, if i can change processor, but.. no money lol later maybe...
but unclewebb, there is no way to unlock extra multipliers, in your program i can Set 8,5, and my processor has a turbo, but when i push'em up the max multiplier is automaticaly down to 7.5, there is a way to set to 8.5? sorry my bad bad english, im portuguese... lol

 

There is this trick.

http://forum.notebookreview.com/win...c-acceleration-ida-both-cores-core-2-duo.html

You need an option in the bios to disable SpeedStep to get this trick to work. Dell has that option in many of their laptops but many other laptops like Acer do not have that option so this trick won't work. It's worth a try.

In theory, once you boot up, you should be able to lock all cores at the highest multiplier but no one has got this working on a Q9000 and sent me any pictures yet.

 

i have a hp dv7 quad edition, with a q9000, and it has a insyde bios, but...i have search alot of tricks, but without sucess! on world wide web i didnt see any tricks to mod this bios..., and i dont have this option on bios, i hope some one help-me i saw people with the insyde unlock bios but in a VAYO pc

 

K well sorry for the delay work was attempting to murder me the past couple days. It unlocks and works great but I feel like this CPU is the devil. I run it at 3.0 Ghz on my 6860FX all the time with prime95 tests showing no errors. But as soon as I run Prime95 with it being shown unlocked even at 2.8Ghz it runs for a minute strait and then just shuts down. Here is my CPU-Z while running at 3.2 Ghz with the multiplier running at 16.

CPU-Z Validator 3.1

I have also sent you an email (its exactly the same name as my tag on here) with my included .ini file from your program ThrottleStop. I am using V. 2.54.

Sorry I do not know if it is a simple error with the fact that I am retarded or if my CPU, being an ES, is actually gayer than a Fanni Pack.

 

How much core voltage are you using. The CPU-Z validator shows a very low voltage number. Have you increased the voltage yet?

Some users have reported CPU-Z VID bugs when unlocking so you might want to try HWiNFO32 instead.

http://www.hwinfo.com/

Have you set the Minimum processor state to 100% in the Control Panel -> Power Options?

A CPUID of 0x10674 is an early ES CPU. That might be part of the problem with your stability issues. I'll go check my mail.

Edit: The log file shows that you have unlocked your CPU to use the 18 multiplier. You need to reset your CPU using the Reset menu option and then start again. Don't go too high with the multi and then save that value or else every time ThrottleStop starts it will use the highest multiplier that you have unlocked. That might be causing a problem.

 

K So I did everything you said but I am still getting the same problem. Even if I set ThrottleStop to complete default as soon as I run Prime95 the computer just shuts down. Not a restart as if I turned the clock to high. I have gone through every option in ThrottleStop thinking that maybe it was the AC to Battery turn off. Also I checked the voltages with the other program and I have realized that even when running with TS on or off that the CPU voltage and speed does go down and back up periodically while running Prime95.

So in simplest terms when I run Prime95 at 3Ghz through bios it runs perfectly. If I run it at the same settings and turn on ThrottleStop at 3Ghz with all the options on or off and also the same voltages stock it crashes upon processing for around a minutes and shuts down.

 

If the reported VID voltage is going up and down then that is usually a sign that either C States are enabled or you have not set the Control Panel -> Power Options -> minimum processor state to 100%.

Everyone else is having excellent success with this so if those settings are OK then I guess your ES CPU and ThrottleStop are not getting along very well. There is no Intel documentation available for what I am doing so I probably won't be able to come up with a solution for you.

 

I have a quad core CPU :
Core 2 Extreme 2.40GHz ES @ MSI-GT628

I alter the Multiplier from 9 to 10

but it doesnt work

 

Did you read the first post in this thread? When you right click on ThrottleStop do you see the menu options listed in the first post? Have you used the Unlock option to unlock your Extreme CPU?

Post a screen shot of CPU-Z so I can see the Specifications for your CPU. If you have an Extreme CPU then this should work.

Edit: You should also check the Disable Turbo option when doing this. You don't need Turbo or IDA anymore if you can raise the multiplier to whatever you want.

 

I did some testing with my XPS M1730 and got the following results.

I used prime95 to stress the CPU and to be sure the settings are stable.

@ 18.0x (3.6GHz), 1.3635V, 79-85˚C
@ 19.0x (3.8GHz), 1.4750V, 84-85˚C

CPU-Z @3.8: CPU-Z Validator 3.1

I also tried 10.0x (4.0GHz) without prevail. I couldn't get the VID higher as 1.5000V. I think it's a system limitation.

Also CPU-Z showed me something strange happening while testing @ 19.0x. Every time when my temperature hit 85˚C I saw the multiplier got down-clocked while ThrottleStop didn't show this.

I think I'm limited at 3.8GHz by the M1730. I can't get the VID higher and it looks like some temperature control down-clocks the CPU to keep it below 85˚C.

 

3.8GHz is already an insane overclock.

 

Welcome to the 3.8Ghz club, I'm also stuck to 3.8GHz and there's no way to get it higher. I can get 4.0 - 4.2GHz but will crash after 20 mins @ 1.50v. Although there are no errors but to me it's pointless running a system at insane overclock levels when it's isn't stable at all. Personally, the whole idea of an overclock is that it works.

Anyway I didn't get any downclocking either, despite running higher temperatures at 90*C (Humidity here is crazy) and from the environment I'm in, where there are no 4 seasons but hot 35*C ambient all year round, I am planning to do a heatsink modification.

85*C is good temp for a 1GHz overclock, considering that there are many other systems with crap cooling - and non OC'ed CPUs and GPUs going over board at 90-100*C...

Cheers.

 

Your CPU was being throttled by the Dell bios using a technique called clock modulation. ThrottleStop is able to report exactly what is going on when this happens. CPU-Z does not. CPU-Z does some sort of approximation and tells you that your multiplier is decreasing which isn't accurate and isn't what is actually happening.

If you put a check mark in the Clock Modulation box and set that to 100.0% then that would help prevent this throttling but I wouldn't do this unless I had a 130 watt or better power adapter. Dell uses this throttling method in many of their laptops to prevent the power supply from over loading and shutting down. If that ever happens, you would need to power cycle the adapter by unplugging it and then plugging it back in.

The practical limit for your system might be 3.6 GHz instead of 3.8 GHz. That's not so bad. A clock modulation setting of 75% instantly kills performance. It's telling the CPU to only work 75% of the time internally and to take a break and do nothing the other 25% of the time.

A VID setting of 1.5000 is the maximum that Intel Core 2 mobile CPUs can use. All of them have this maximum limit.

 

Our M1730s are armed with a 230W power adapter. I guess should be sufficient, two 8800M GTXes in SLI consumes 130W of power. Leaving 100W for the rest of the other components and the processor.

But yeah I'm starting to believe 3.6GHz is pretty much the safe barrier. That's an 800Mhz overclock.

 

Dell usually throttles their laptops long before power consumption gets anywhere near the rating on the sticker. An adapter rated at 230 watts DC would typically start throttling at 200 watts DC output or less. The bios could also be using temperature to trigger clock modulation throttling but it's often times power related. It's impossible to say without some thorough testing. The screen shot shows throttling while the core temperature is under 80C so that's why I thought the throttling might be power related.

 

Yes, with our power supply of 230W this isn't an issue.
I will test again in the evening when I get back home and will put Clock Modulation at 100%.
Stupid me, I didn't notice that in the first place. Well yeah, nobody is perfect, I guess.

I like the idea my rig can handle 3.8GHz. It'll give me a nice performance boost in the future. Thanks again a lot unclewebb.

 

Remember, if you burn your house down by locking clock modulation at 100.0%, it's not my fault.

Sometimes when you try to lock this at 100%, the laptop will fight back and try to lower the multiplier more aggressively.

Now that you know what to keep an eye on, maybe do some more testing first before locking it. Is the throttling temperature related or might it be power related? It can be difficult to tell sometimes since the two are related.

 

I already tested it and guess..... I didn't burn my house down.

Locking the Clock Modulation did the trick. Although I reached temperatures like 94˚C. This is the furthest I can go with my rig.
With a 3.8GHz clock I'm satisfied. 4.0GHz would have been a very nice bonus, but my CPU isn't stable even without prime95.

My CPU is just to much hungry/thirsty for power and the max I can feed my little precious is 1.5V. Also that causes a lot of heat.

 

Is it just Dell that is using clock-modulation method for the CPUs or is there another company out there that uses it?

 

Y'know, I think this topic is more suited to the Hardware forum than the Acer forum; this is far too general.
Moved.

 

Thanks TehSuigi, you are absolutely right.

I think the Intel Clock Modulation feature is mostly being used / abused by Dell and Dell's Alienware line. When you look through the NBR forums, most of the throttling talk is in the Dell section. Edit: I forgot. Acer uses chipset clock modulation too.

Before software found out what was going on and started reporting this, it was easy to throttle a CPU without anyone ever noticing. A lot has changed since Dell first started using this. CPU-Z will show you a reduced multiplier and HWiNFO32 will show you reduced MHz and RealTemp reports clock modulation now and so does ThrottleStop. I don't think any software was reporting this two years ago when Dell started throttling their Latitude E6000 series by using excessive clock modulation.

Most other manufacturers might use some multiplier throttling if it is needed. I think the HP Envy 15 still does this when on battery power which is somewhat reasonable. On a Core 2 when you drop the multiplier down to 6, that is an easy way to instantly control power consumption and heat without needing clock modulation that sometimes gets left on for way too long. As in 15 minutes after the fact too long.

Interesting how other manufacturers have found ways to produce laptops without needing to use the punishing clock modulation trick that Dell (and some Acer models) are using.

 

Acer has to deal with the chipset clock mod, but my Definitive Guide to Throttling topic covers that well enough.
The Core 2 Extreme unlocking/Dual IDA modes, however, are more general topics; good software like ThrottleStop needs a wider audience.

 

Yes, that's why I requested a few pages back earlier in this thread to have it moved to the Hardware forums. It needs more exposure; its sad not many are aware of this wonderful tool yet.

 

this software is awesome.. only if u could OC using it in core i series... that would make this software hot hot hot and even ppl would be willing to pay for it.. but even in this form , its awesome if i could only be bothered installing 1 more software.. anyways , does this do undervolting? If it does i'd just install this instead of RM clock.

 

Yes, ThrottleStop can be used to under volt Core 2 CPUs. It's not as fancy as RMClock but accomplishes pretty much the same thing.

Some users like the extra control of RMClock but with the newer 45nm CPUs, I've found that there's no need to get too fancy with coming up with the exact FID/VID settings.

 

is there some guide to this? Also what features does ThrottleStop not have compared to RM clock?

 

There is some basic documentation in html format included with the download but it's over due for an update. You can push the F1 button while ThrottleStop is running to see this info.

The main feature is that RM Clock lets you set up a different voltage for each multiplier. I found that most CPUs spend a very small percentage of time at the intermediate multipliers so I didn't include this feature in ThrottleStop. It makes for a simpler program that is easier to set up but RM Clock has better control. RM Clock also draws some nice graphs.

One disadvantage of RMC is that it does not support the newer 45nm CPUs with their half multipliers but there are a few different fixes for that.

After that, both programs have some unique features. With bios support, ThrottleStop lets you lock both cores of a Dual Core in IDA mode. It also lets you unlock the multiplier on the Core 2 Extreme CPUs. RM Clock can't do either of those tricks. ThrottleStop takes up less memory and uses less CPU cycles but most users have lots of memory and processing power so this really isn't much of an issue.

Use whatever program you like or use them both together. They both have some useful features.

 

I use RMclock to manage the stock 2.8GHz VID when it downclocks from 3.8GHz and when the computer is not doing anything. I like that feature. Also I like RMclock to manage the VID settings at battery mode and force to run at 2.0GHz + VID control for that speed. I use TS to manage clock modulation and VID settings at 19x multiplier. And I'm glad to use both.

 

SomeFormOFhuman: I had an idea for another feature or two for ThrottleStop. I was thinking about adjusting the Power Saver Option so it is more useful. Instead of it dropping down to the 6X multiplier, maybe I could make this more user adjustable. For yourself it might be handy so you could create a 2.8 GHz idle profile and then a 3.8 GHz full load profile. It's somewhere on the things to do list.

With that extra feature maybe ThrottleStop will be good enough so you can retire RM Clock or save it for when you want to draw a chart.

 

uncle web if yoou can make this possible for the i7 processor, your the bomb!

 

@ unclewebb
I'm stuck with a nasty CPU. It'll not let me run at 4.0GHz at all with 1,5V. Do you think a FSB mod will make my CPU run at higher clocks or I have to find myself another X9000 CPU?
My 3DMark06 score 16465 isn't that bad, but I think there must be more with these M1730's.
