How to Unlock the Core 2 Extreme Multiplier in Windows

The X7900 is running with a multi of 17 at 1.3875 volts.
Running Orthos it gets quite hot (>95°)
Thanks to your software i let it switch back to a multi of 15 at 1.2375 V.
So we get a constant temp of 95° running Orthos (small FFTs)

While gaming and benchmarking the temperature keeps around 80°, no switchback ever happens.

I chose the X7900 because the X9000 is almost unavailable now and I don't like to spend 400 bucks more just for a speed increase of >200 Mhz.

BTW: Pls send me your paypal adress for the donation.

Thanks again for the great work,
rasric

 

The X9000 is 45nm and also has 6mb of l2 cache. It is not just a 200 Mhz increase. Also since it is 45nm it will run cooler and use less power so you can OC it more.

 

I wish more people knew about ThrottleStop's Alarm feature and ability to switch profiles based on core temperature. This is a great way to keep a lid on things and allows users to have a very aggressive main profile without having to worry about things getting too out of hand. I sent my Paypal address to your email address. I'll try to add a Donate button back to ThrottleStop in the future to make things easier.

 

I am aware of this, but i don't want to spend 400 bucks for an outdated cpu.

@unclewebb: Enjoy your beers and carry on with your good work.

 

I wouldn't spend 400 on a X9000 also. It is not really outdated, when overclocked it keeps up with the mobile i5s and i7s,

 

I agree, but the whole set of 8800m SLI @ 650/1500/1000 and the X7900 @ 3.4 Ghz matches perfectly now. I already had a notebook with a i7-820QM & HD5870 but i was getting to hot in SE-Asia (>100°). I rturned it and switched back to my old rig thats now running fine. Only if i can find a used Asus G73 i will change again.

 

Hi, for intel SU4100 VID voltage seems not able to go lower than 0.900. Is CPU supported by ThrottleStop or CPU voltage simply won't go any lower than 0.900.

 

Try HWiNFO32.

HWiNFO & HWiNFO32 - Hardware Information and Analysis Tools

It will show you the VID limits for your CPU. Every CPU is unique. ThrottleStop should be reading your CPU correctly. It sounds like 0.9000 VID is as low as your CPU can go. At idle, these CPUs automatically go into a low power sleep state where the VID will drop lower than 0.9000 but ThrottleStop ard RM Clock don't allow you to access these lower VID values.

 

usually , 0.95V is the minimum... if throttlestop can't go below 0.9V , nothing can.. so the limit is 0.9V..

 

Thanks for the prompt reply unclewebb, and sean473.

 

Unclewebb, the bug does still exist and it is still kind of dangerous. Since one of the first replies here.

Heres how you recreate the bug:
1. turn on
2. unlock
3. increase multipliers until BSOD
4. restart, get BSOD
5. restart with last good config, BSOD
6. restart in safe mode, BSOD
etc...

I think the only thing saving me is downclocking on battery.
When I do manage to start again, it hasn't saved the overclock. I guess it could just be bouncing around in the system and doesn't reset in some cases.

It doesn't always happen on everyones system, for whatever reason.

 

There is a seller on alibaba who offered me 180$ x 10 if anyone wants to organize a group buy....

 

If you increase the multiplier until you get a BSOD then ThrottleStop isn't saving anything and causing this problem. There's nothing I can change to make ThrottleStop handle this better. When searching for the outer limits of what your CPU can do, I also wouldn't have ThrottleStop in my Startup folder or in the Task Scheduler.

After you screw yourself like this, maybe you should try turning the power off to totally clear the CPU. When you hit the reset button on a computer, it should clear out the change that ThrottleStop makes but if it doesn't then doing a complete power cycle definitely will. A BSOD can cause Windows to get a little confused. From what you've described it sounds like Windows getting screwed up is the problem. What Windows version are you running?

The big question is why would you increase the multiplier until you get a BSOD? With every step up in the multiplier you should do some thorough stability testing and prove out one multiplier and how much VID voltage you need to be 100% stable before trying to push the multiplier higher. When you randomly increase the multiplier with no regard to stability, you can nuke Windows and can end up having to do a complete re-install so try to use some caution.

 

Yeah, I guess I realized its my OS.
I've been having some extremely strange other issues lately so I know you or throttle stop is not to blame.
Part of my disregard to instability was that I knew it was stable at 3.3 before I knew about the "core 2 mobile" option. I had the voltage set a few steps up from what I thought was default.
When thats turned off, and you mess with voltage, is it reporting correctly? man, scary to think I had it at like 1.45.
Anyway I'm happy now. I know my sweet spot for over 2.9 is just over 1.3 at least.
I also now know that when power cycling everything connected to the notebook doesnt work and it seems entirely lifeless, power cycling my adapter does. Which is good to know

One other thing...
I just got an sp9400. ironically 'the same model' as my q9200.
I can't get it to overclock. Added extreme=1, tried different versions with no luck.
Any tips for this?

Or has anyone heard of an sp9400 without unlockable multipliers?
its really puzzling. cant even get it to x9.5....

 

Haha, I have that same CPU, it's not unlocked and my ES chip has IDA disabled and no temp sensors.

I wish I could OC it with throttlestop.

Still a good CPU anyway.

I got it to 3.65ghz but my ram wasn't stable enough to let me validate it.

 

yeah, i know LOL to be honest I was half thinking it had the unlocked multipliers because of your sig. Mine is ES too, they all are, except for the very few that come soldered to dell e4300.

shame i can only get it to 2.58 with the m860 and then it screws my graphics... hopefully my m570 will produce better results.

i also bought a temp sensor shipped in a handmade bag LOL eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices
i should have picked up some spices and saved on shipping i feel sorry for the thai actually :/

 

How does that temp sensor work?

 

I read through this thread again and I'm confused.

If I turn on Throttlestop, set my ratios and TDP/TDC, then click save and quit... does that save only until I restart, or does the setting survive restarting?

 

err i like a cricket?
except it might be exponential. basically it gives you some kind of a pulse.
I dont know how to accurately convert it into a reading yet, maybe just sort of calibrate it with a cpu that does have temp sensors.
oh but it is a chip, with plastic casing a few mm so my idea was to try and slim it down and then work it into a copper shim.... lol...

It will save your FID/VID (overclock) but wont continue to "stop throttling".
my issue was that it sometimes saves it when you dont want it to when you get a BSOD

 

For the i7-940XM, when ThrottleStop is used, it changes the turbo TDP/TDC and turbo multipliers by writing information directly into the CPU. If you reboot your computer, all that information is lost. The only way to get those settings back is by restarting ThrottleStop.

If you restart ThrottleStop and your previous settings were not saved in ThrottleStop then that is a problem. One user created a ThrottleStop folder on his second hard drive but for some reason, he didn't have Write privileges to the ThrottleStop.ini file that saves all of the configuration changes. When he clicked on OK and Save, nothing was getting written to this file because of that.

If you have that problem, right click on the ThrottleStop.ini file, select Properties and then click on the Security tab and make sure your account has Read/Write access to this file.

If that doesn't answer your question JohnnyFlash then be more specific and I'll see what I can do.

 

Nope, that's exactly what I needed to know. Thanks.

 

One more thing I just noticed: Shouldn't a 940XM always be running at 2133MHz or higher when using the "high performance" profile with the minimum cpu speed set to 100%? Mine flops around 1.6 -1.7 when idling under these settings.

 

The Core i mobile processors are designed to idle down regardless of how you have them set up or your Windows settings. I think someone found a registry tweak to force their Core i XM laptop to run at full speed but it resulted in a lot of extra heat and wasn't worth it. If you really need to know what this tweak is then I seem to recall that 5150Joker experimented with it.

CPU-Z ignores that these CPUs are idling down like this for validation purposes but they really do slow down. ThrottleStop will correctly show that the multiplier is hunting up and down as one part of the power profile will disagree with another part of the profile. If you set the Minimum processor state to a low number like 5%, you can make these fully idle down to the default minimum multiplier but setting that value to 100% does not make a mobile Core i CPU run at full speed. This feature seems to be partly what's behind the slow SSD performance when lightly loaded problem that many users have reported but that's another story.

 

Unclewebb,

Throttlestop is an amazing piece of work, i have been using it for ages to stop throttling on the Acer 8930g with a P8600.

But now i see it can overclock extreme procs, and i'm looking at the x9100 on ebay but what i need to know is:

Should I get the C0 or the E0, and what are the pros and cons ?

I know one is retail and one is an engineering sample, but apart from that, thats all i know, please help this little n00b out. Thanks.

 

I think there should be retail versions of both the C0 and E0 steppings, and there should be ES versions of both too.

E0 should run cooler and will be overall better.
C0 would be cheaper.

I would try to get the E0 if you're going to overclock.

 

Thanks for that, I think I'll definitely be getting the E0 then, can't wait to fit it and see the magic

There are things in forums here and there saying that the overclocking utility in Throttlestop may not work with E0 procs, do you know if this is true?

 

Have not heard that before, can you post a link?


As long as you have a core 2 CPU that's extreme (with unlocked multipliers) it should work with throttlestop no matter what stepping.

 

Oh right, the core parking feature. I remember that now. Ok, no problem as long as it's normal.

 

Throttle stop is an amazing work , thanks!
I will share my experiences,
I have g51vx and i replaced the p7350 quite a while ago to x9100 - c0
the temps skyrocketed, and i did undervolt etc.
now,i found this software,
here are my results

x9100 @ 3.6GHz stable, in games etc, at stock voltage of 1.23, powersaver enabled with SLFM @ 800MHz, lower than 1V.
for some reason, cpuz doesnot show higher than 14x, and when i 14x @ 1.238 , it bsods, 15x @ 1.250 everything crashes, kernel goes mad, but no bsod

i did run orthos for a 10 mins,the temps skyrocket, but it is not a good estimate of a normal use, it is very heavy , so i will be fine ...
i don't have any throttling issues, so, it's good.
the performance test passmarkgives 3100score ...

 

You're welcome for ThrottleStop.

When using HWMonitor, you need to edit the configuration file so it can correctly report your core temperatures. Edit hwmonitorw.ini

CPU_0_TJMAX=105.0

The Intel website shows that 105 is the correct value for your X9100.

http://ark.intel.com/Product.aspx?id=35431&code=x9100

Unfortunately it is usually set to 100 so your temperatures won't be reported correctly. It should match up to ThrottleStop after this fix when you click on the Temp button.

You have an excellent CPU. Give it some more voltage and I'm sure you can run it with a x15 multiplier. Just don't run Prime95/Orthos at that speed for very long.

 

thanks, i think i have a problem over 14 and 13.5 it crashes at 1.2375
i may need to give it a little more ..
the temps are crazy at that voltage
right now, i am running 1.225 with 13x it seems very stable, but i need time... may be in 1 week, i can confirm it is stable, because today, 13.5 failed me many times. it is very tedious work, i will do it though.
do you know what kind of voltage is very dangerous except heat?
thanks for the reply again,
also would you mind if i make a youtube video of this, to increase the impact?
i willl let you know before 1i publish the video...
please respond, you are an excellent inventor!

 

I would love to see a YouTube video. If it is a good video, I will include a link to it in the next ThrottleStop download.

The voltage you are using is very conservative. I use as much voltage as is necessary so that it is stable. One user with a QX9300 used the maximum VID voltage of 1.5000 and ran his quad for a screen shot or two at 4333 MHz.

scook9 - Core 2 QX9300 (2.53Ghz) @ 4333MHz - 4333 mhz CPU-Z - hwbot.org

It creates so much heat that he can only do this when it is in his deep freezer. I don't recommend using more than a VID voltage setting of 1.400. You will be limited by heat during normal use before you ever get that high. I think some of the Dell laptops have better cooling which is very important when unlocking these CPUs.

 

i tried it in my asus when the back plate was taken out and it is directly under blowing airconditioning ....it doesnt heat there, for sure
i willdo my best about the video and show you, so that you can decide, i willprobably do it within this week.will have to edit etc.
i know people go as high as 1.4 in x9000, but, ...i am not sure,...i will think about it,
13x and 1.225v is a pretty stable setting for me, during gaming, at highest perf. only, the temps only go up to 84ish, which is basically nothing for this since it is not orthos

 

as soon as i wrote here, i decided to give another try, i set the multiplier 14x,and voltage as high as 1.26, windows crashes and then bsod. one has to turn off the computer completely before windows can start without crashing.
perhaps, over 14x one needs to supply logarithmically more V.

 

I run for most of the time my x9100 @ 3.2 GHz 1.1750 Vcore x12. I can run Orthos stable 3.45 GHz 2.2650 Vcore 13x. Orthos over heats me but also 3.6 GHz 1.3125 x13.5 Vcore and 3.7 GHz x14 1.3625 Vcore. The two later settings all regular programs seem to run fine but it does get quite hot.

For every day use with the SSD there seems to be no major advantage to anything over 3.2 GHz so I don't bother. I figure it will just last that much longer not exposing the system to so much heat and power draw............

 

ozdemirhan: Be careful when playing. It is very dangerous to try for a big MHz number when you are not using enough voltage. You can corrupt and damage a Windows install by doing this and you might have to do a complete re-install. Not good.

 

it happened similar times and i did have bad BSODs and reset loops.
i was able to recover with last good settings from f8 menu each time, thankfully, and once i had to do safe, but, also once i had to remove battery etc,
but i recovered.
last night the laptop had a BSOD and did not restart when i was sleeping when i woke up the fan was spining pretty good, i am lucky it didnt burn the cpu
i think it is still safe since it turns off cpu...

 

i will work on the video tomorrow, i have a meeting tomorrow, it should be pretty straight forward.

 

I have a new record of mine to shar with you guys.
I have broke 3.740 GHz limit with 1.3V

i think i can go a little lower on voltages and do the cooling mod.
BTW over 14x, it doesnot work, it could be the max multiplier for this board,
the temps are not that bad at all,
i am curious if i can combine setfsb fsb overclocking and this and break 4GHz/

 

ozdemirhan: Nice work. An X9100 + ThrottleStop makes for a speedy little laptop and very competitive with most newer Core i based laptops.

You might want to try upgrading to Super PI mod.

Download Super PI Mod v1.5 | techPowerUp

It gives you 3 digits after the decimal point so it is easier to see your progress. If you run a time like that I will post it in the Core i thread to see how the competition compares.

To get HWMonitor to report your correct core temperatures you need to edit the hwmonitorw.ini configuration file. Make sure this line is set to 105.

CPU_0_TJMAX=105.0

Here's the official Intel documentation. Check out the Tjunction line for the correct value.

Intel® Core 2 Extreme Processor X9100


I heard another user mention that their board maxed out at a 14 multiplier. Can you post a screen shot of ThrottleStop and CPU-Z with ThrottleStop set to 15.0 just so I can see. Thanks. I'm not sure if this is a limitation of the CPU or the limits of your board.

 

I just recommended my brother to get the T7600g socket m 65nm merom core 2 duo as the fastest upgrade for his T60p (which can only use socket m) as it can now actually take advantage of the unlocked multiplier thanks to your efforts with Throttlestop. I was just playing around with how high it can go and It froze at 3.8ghz:
http://imgur.com/FcsKS.jpg
I was using dustoff to cool the cpu down to 0 C

 

I was working on the video and camstudio stupid program crashed so, i lost all the record, otherwise the video would be up and running, and I will be doing your suggestions and report back.
All I can say is this is just awesome, God, I wish I did have a better cooling on this device...
x9100 has 6mb cache, already outperforms 620m with this...
i will give better and more organized results in a table.
I am prepping it.

 

Hey,

Its the noob again, asking more nooby questions >.>

So I cant decide between these two procs, any help?

New Intel CORE2 e8435 SLAQD OEM! similar to x9100! on eBay (end time 21-Nov-10 01:08:37 GMT)

New Intel CORE2 X9100 QHBQ Super low Temp! on eBay (end time 23-Oct-10 13:11:55 BST)

 

The e8435 is not extreme so you can't overclock it with throttlestop.

But you will probably be running the X9100 at 3.6ghz. Is that extra 600mhz worth $111?

 

phew, thanks for telling me that, i just assumed it was extreme aswell, I really want to overclock so i think i'll do a little saving up ^_^

 

Here's an X9100 running a 15 multiplier so it looks like if you can't get beyond 14 then it must be a limitation of your board and not the CPU.

CPU-Z Validator 3.1

eatbuckshot: 3.8 GHz for a 65nm CPU is living on the edge but it looks like you're having fun.
Lucky it's your brother's laptop.

3.4 GHz might be doable for 24/7. A T7600G is a great upgrade for an older laptop with the help of ThrottleStop.

Here's some more info about these CPUs and the guy that helped me to get this figured out.

http://www.notebookforums.com/thread228991-2.html

 

I did get 15x to work with 1.3V... didn't last more than 20 seconds, the voltage related parts are sending alarm to proccessor, I guess and every software starts to crash above it, so, I am happy with 13X @ 1.2250V in my x9100.
I have taken a video 1920x1080 HD, it is 3GB LOL. I never uploaded anything to youtube before, so, I will have to learn that lol, and I will send you the link to check if it is OK>

Unclewebb,
I also have a t9500 @ 2.6GHz - sony vgn-ar770e/b. with intel pm965...
I am trying to buy x9000 @ 2.8GHz on ebay and replace it, I am pretty sure the bios will work with it. with x9000, which I am planning to overclock with throttlestop... I am planning to reach 3.4GHz, so that I can use that laptop more effficiently, its idle temps are 35C ish, so, it is perfectly fine for overclocking.
do you think i can do this in that one as well? have you had any experiences that throttlestop does not work at all in any core2 extreme?

thanks!

 

Throttlestop can certainly unlock the X9000. Btw have you tried taking the multi to 14x (your limit) and then OC the fsb for additional speed. Can make up the different of one less multi very easily. I intend to do just this with a QX9650 to get the clocks I want when I have time

 

Unfortunately sony doesnot allow setfsb... abooo does not want to support it... he was not very nice to me, honestly...

 

There is no problem overclocking the X9000 with TS, sometimes you can even hit higher than 3.4GHz depending on the cooling capabilities of your Sony, and also the stability of the X9000. Just make sure you get a QS X9000 with temp monitoring sensors.

PS, and I hope your AC power supply is up to it to handle the overclock as there will be voltage change. But universally, for an X9000 to run at 3.4GHz, 1.2625v is said to be the most stable undervolted VID.
