How to Unlock the Core 2 Extreme Multiplier in Windows

Well I have good news!!!! I don't know if you remember all the trouble I was having with running my X9000 and it freezing when using ThrottleStop but I decided to try using your newest version and low and behold it runs great!!!!

Now I just wish I had a freaking clue what made the older versions do that!

Anyway, Thanks for the great program!

 

Wow is all I can say.

Just played around with this on my m4400 with a QX9300. I've already removed the CPU and reapplied it with some high quality paste so gave overclocking with throttle stop a go.

It's runs completely stable at 3.6ghz even after run stress tests. I've lowered it slightly to 3.2ghz just for peace of mind. Temperatures are barely higher than when running unclocked.

Amazing, it's very nearly giving the same performance now as the i7 920XM in my m6500. A quick 25% cpu performance boost!

 

3.6 Ghz ! ! !When is lift off ? ? ?

 

There is a huge amount of head room in the Core 2 design. Intel never needed to release the beast because there was never enough competition from AMD.

3.6 GHz is a happy spot for Core 2 based CPUs. As long as your core temperatures are reasonable, you won't have any problems running at this speed. Beyond this point, voltage and heat start to go up too quickly for most laptops.

If your i7-920XM ever starts feeling slow, just right click on ThrottleStop so you can let the 920XM run at what it is capable of too. Intel builds a lot of performance into their Extreme CPUs. Now we finally have a chance to use it all.

There might be a reason why Intel didn't want this little secret getting out. Now there's no reason to upgrade to the latest and greatest and hot running Intel Core i CPUs.

 

So for the folks who has a X9100, I was finally able to OC it past 3.6.
im running my Asus G50vt at 4.0 Ghz, x15 multi, 1.4625v.
Stable after heavy benchmarking, runs hella hot though.

The X9100 is an ES btw, best $160 I've ever spent.

 

Any news for a version that supports the i7 extreme cpus?

 

Okay I have Throttle Stop & my machine working together again!

I must confess that when I first started using TS a few weeks ago I was not paying full attention and let the TJ max reach 98'C on the first two cores of my Qx9300 while running prime95 which then threw errors and throttled back.

Since then I have not been able to run prime again stable above 3Ghz without BSOD. Went ahead and purchased a Q9200 to compare to see If I damaged the QX. Same results, only achieved a 400mhz o/c to 2.8Ghz prime stable.

So I put back in the Qx tried again and no joy
Well tonight I reinstalled Win7 and now TS and my machine are working well together again
So I assume by reaching the TJ max screwed up windows or tripped up something in my hardware besides my CPU.
Anyways going to be alot more vigilant here on out.
Learnt my lesson but I will continue on.

 

It already does. i7 920XM and 940XM or any extreme CPU with an unlocked multiplier. It even supports the desktop 980X.

 

ncc1701k: I love seeing signatures like that and SomeFormOFhuman's signature as well. It looks insane but I ran my E8400 at 4.0 GHz for a year or two without any problems. When they blow up, what's another $160? Thanks for proving that the X9100 E0 (ES) is a hell of a processor. I've been recommending them to a few users as well as some of the Quad E0 (ES) processors.

Cygnus X-1: I have no idea what happened to Windows but I'm glad to hear you got things sorted out. You might want to download RealTemp.

http://www.fileden.com/files/2008/3/3/1794507/RealTempBeta.zip

It has the ability to read the thermal throttle bit. At the bottom of RealTemp in the Thermal Status area it should usually say OK for each core. If you trip the thermal throttle for even a millisecond, RealTemp reads that info directly from the CPU and OK will change to LOG which shows that a thermal throttling episode was logged within the CPU. The best thing about this is you don't have to have RealTemp running. If you ever notice a very high peak temperature, you can start up RealTemp after the fact and it's still able to read this bit from within the CPU to warn you that you've gone a little too far.

Tripping the thermal throttle shouldn't cause Windows or anything else to bug out so I'm not sure what happened. Here's my testing of this feature. On my desktop E8400 I did some overclocking and some over volting and I disconnected the fan to create lots of heat. This CPU spent 3 hours bouncing off the thermal throttle without skipping a beat. I forgot to mention, I had Prime95 Small FFTs running at the time. Not a single error. The word HOT means that thermal throttling is in progress.



Windows Vista was still fine after this bout of insanity.

ThrottleStop should also work on the new desktop i5-655K and i7-875K that have an adjustable multiplier. ThrottleStop is also the only program I know that allows you to adjust the turbo TDP/TDC limits in the Core i CPUs that support that feature. I wanted to make sure that TS was going to be around for a while.

Edit: One feature that not a lot of people seem to be using is the ThrottleStop alarm feature. You can set an alarm at say DTS 10 which means the CPU is 10 degrees away from the thermal throttling point. When it reaches this temperature, it will automatically switch profiles to whatever profile you like. You can have your main profile at 4.0 GHz and then you can have a secondary profile at maybe 3.2 GHz or 3.4 GHz with the VID voltage reduced a little. This will instantly get your core temperature under control and as soon as it gets below the alarm temperature, it should automatically switch back to your high speed profile. Once set up correctly, this feature gives the user a lot of automatic control over their peak core temperature. You can also control your CPU speed based on your Nvidia or ATI GPU temperature.

 

Hahaha!!! If you play the game of Truth or Dare, I'd say my X9000 is only at 3.8GHz 1.450v and a Dual IDA 2.7GHz T9300 running in my Inspiron 1720.

Oh the sig... It's just to show how high and stable the fellow X9000 went. The only thing true are the GPU overclocks and benchmarks. And the rest of the other specs. LOL.

 

Hallo!

I have couple questions for you unclewebb.

I switched cpu in my laptop. Is not Extreme, is T8300. But i can change half multiplier in Ts, is working good. Next thing i have discovered IDA - 13 multiplier in Rightmark but also in TS -13x200-2.6Ghz, which worked sometimes and only for 1 s. Than cpu go again to 2.4Ghz -12x200.

EDIT: Ok i found it
SuperLFM :
Ida : Intel Dynamic Acceleration overboost for single core.

 

Thanks again, absolutely superb utility. I've just started using it all the time with the 920xm. Gives a nice little perfomance boost just by ticking the multiplier.

 

ex.treme: Turn off RM Clock, run ThrottleStop, put a check mark in the Set Multiplier box and set that to 13.0, uncheck the Disable Turbo box then run a single thread of Prime95 and use task manager, Set Affinity... to lock Prime95 to a single core.

Now have a look at the numbers in the monitoring area on the right hand side of ThrottleStop. It should be very easy to see IDA in action. RM Clock does not report when the CPU is using IDA mode correctly and CPU-Z rounds the multiplier off so you can't depend on that either.

wrightc23: You have ThrottleStop's two favorite processors; the QX9300 and the i7-920XM. Each of those CPUs has a huge amount of performance hiding inside and is just one right click away.

 

Master webb, I've a question:

Any support for the E8335 iMac CPUs? There are (though not alot) of folks using the Socket P iMac CPUs running in their laptops. (One or two guys uses it in their Gateway FX 7811) These CPUs are basically, like Nvidia, "rebadged" for the iMacs.... They're typically based from the T9xx FSB 1066Mhz series.

The E8445 is essentially a 44W TDP and 55W TDP (Yes two versions exists) CPU based from the T9900.

Another one is the E8335, a 35W TDP CPU based from the T9800.

The rest of the other iMac CPUs can be found here:
http://en.wikipedia.org/wiki/List_o...2Penryn.22_.28Apple_iMac_specific.2C_45_nm.29

The one I'm needing UV'ing assistance is the E8335 - unfortunately showing 1.1625v being the lowest voltage. Which I know it can go much lower than that for the T9800.

RMclock was needed to go as low as 1.1v.... All I need now is, I need to go lower. (Typically the T9800 is stable at 1.0625v or lower, from what I've seen) I'm not sure if TS is built to cater these iMac Socket P CPUs...

Please advise. Thanks. Laptop is a Dell Studio 1555.

 

I'll add those CPU models to the next ThrottleStop update so they are automatically recognized. Until then, I built an option into ThrottleStop so if a CPU is not being properly recognized as a mobile CPU you can fix that yourself. Just add this to the ThrottleStop.ini configuration file.

MobileCPU=1

That should let ThrottleStop use the correct formula so it will report VID voltage correctly and it should also open up the SLFM option so you can access the lower voltages. Let me know how it works out. Can you do the Dual IDA trick with these Mac CPUs?

RM Clock doesn't seem to be showing IDA mode or SLFM mode. It's possible that this CPU does not support either of these so you won't be able to go lower than 1.10 volts since the sub 1.00 volt VID settings usually only work when a CPU supports SLFM.

 

Thanks webb. I don't have the laptop with me now to test it, but I will try the Dual IDA and MobileCPU=1 when I get hold of it...

EDIT: Woah, so since there is no SLFM option (grayed out) so the lowest will still be at 1.1v?

 

If Intel built these CPUs and didn't include SLFM in the design then you won't be able to choose a super low voltage or super low MHz and it looks like IDA mode is not supported either.

It will be interesting to see how one of these runs in a PC laptop. If these CPUs support the deep sleep states like C3/C4/C6 then at idle, they should still drop down to a really low voltage, way less than 1.10 volts. If they don't support those modes then I think you will see higher idle temperatures.

Here are some general ratings from the Intel Spec Update document for the X9000, X9100, T9600, etc.

VID = 0.650 - 0.850 [C4]
VID = 0.600 - 0.850 [DC4]
VID = 0.350 - 0.700 [C6]

ThrottleStop and RM Clock don't let you adjust these.

The MobileCPU=1 option will unlock the SLFM box so it is not grayed out in ThrottleStop but if the CPU doesn't support SLFM then clicking on this box isn't going to change anything.

 

Do you have any recommended (stable) setup for the QX9300?

 

3.2-3.3GHZ @ 1.275V

 

Here's Soviet KGB doing 3.5 GHz with a VID setting of 1.225

http://img809.imageshack.us/img809/617/18027.jpg

A 12.5 or 13.0 multiplier should be OK for day to day use but you have to do some testing to see what a CPU likes. No one knows your room temperature or how good the cooling system on your laptop is or anything else about your setup. Every CPU is unique so to find out what it's capable of, do some stability testing with Prime95 and maybe some 3D stability testing with 3DMark or similar. Only go up a little at a time and make sure it is stable at each step before going higher. Jacking the VID to 1.5000 and then going for 4.0 GHz in one big step is lots of fun until your CPU goes ka-boom.

Edit: A couple of pages ago Marc was running his QX9300 at 3.75 GHz with a 1.3500 VID setting.

 

This is what I have done now that I have my Pc & Ts running well again. Upon loading TS I left the default VID at default IDA of 1.237 and increased the multi to 12 for 3192mhz. Ran prime95 until temps reach low 90'c and then stop test. Then I lower the VID down one step and rerun prime again. I just keep repeating this process until I find the least amount of VID to stay stable at 12 multi which is 1.175 thus far.

Next I will be increasing and testing from this point on.

Here are some screenshots of my tests along with max wattage draw with these settings running prime & 3dmark06.

 

Thought I'd share my experience:

Since as far as I know, ThrottleStop doesn't support command-line profile loading, I created three modified ThrottleStop ini files (one for overclocked, one for stock, and one for powersaver); this way, ThrottleStop's settings would depend on which ini file was named "ThrottleStop.ini". Next I made three batch files, which each close ThrottleStop, rename the ini file according to the performance mode I choose, and re-launch ThrottleStop. Then, to have these performance modes launched with hotkey presses, I installed AutoHotKey, and did some registry editing to remap my useless "Web" and "Mail" hardkeys to launch my overclocked and stock performance modes and set "Windows+S" to launch the powersaver mode. I then combined this with the nVidia System Tools profile feature, so that in addition to changing the CPU's performance, the GPU's performance is changed accordingly as well, by using AutoHotKey to directly execute the ".nsu" file.

The result is "one-touch" complete system overclocking, thanks to ThrottleStop and AutoHotKey.

 

Waaahhh your laptop can pull down 230watts?
Crazy beast!

 

Just got my x9100 ES, running 3.450 GHz stock vcore...........

Edit, 3.6 GHz @ 1.275 and 100% stable, Thankyou UW................

 

Can't seem to get a consistent locked multiplier on this 920xm machine. Not only that, but there's an obvious discrepancy between tstop and cpuz's idea of what the multiplier is. Power scheme is high performance, min set to 100%. Clock checkboxes have been tried in all combinations with no success. throttlestop _does_ recognize the cpu properly, so I'm a little out of ideas at this point. Any ideas?

Thanks.

 

Nice looking numbers TANWare.

spill: At idle, Core i7 mobile CPUs automatically go into deeper sleep states regardless of how you have them set up. ThrottleStop reports the average multiplier using the method recommended by Intel in their 2008 Turbo White Paper. The best way to test the multiplier is to put some load on your CPU. If you run a single thread of Prime95 and lock it to a single core, you should see ThrottleStop report that core using a very high turbo multiplier while the average multiplier on the other cores won't be nearly as high because they are mostly asleep.

In the Alienware M17x, when the Extreme CPUs are fully loaded on all 8 threads, they can use the highest multiplier on all 8 threads. I'm not sure how your 920XM responds when loaded like this.

Have you right clicked on ThrottleStop and played with the turbo multiplier settings or the turbo TDP/TDC settings yet?

Don't worry about your idle multipliers. Everyone's mobile CPUs work the same. Some software has decided it is easier to ignore that so it makes for better looking screen shots.

This thread is for the Core 2 Extreme CPUs. I don't own a 920XM but I'm interested in learning more about how these CPUs work on different motherboards when using ThrottleStop so send me a PM if you have some more info or some more test results.

 

Just to let everybody know that have older computers with the 945 chipset (in my case a Toshiba A135-s4487), that this program works with the t7600g that was originally only available for the Dell XPS m1710. I haven't really pushed it past 2.8 ghz at 1.25V because temps keep rising above 95C at full throttle. 2.6 ghz is ok at just under 90C with 1.2V.

 

Thanks for confirming that the T7600G is supported. In theory I thought it would be but it's always nice to know. Now you just have to find a way to improve your cooling to get a few more MHz out of it reliably.

 

Well with Prime95 x64 my CPU wasn't stable. Wierd though fully stable with everything else but this torture test kills the cpu so I've upped the voltages to below except 3.6 I run at 1.3000 as the CPU errored a worker 9 minutes in at TSZx = 96C and I figure that is good enough for when I need it. I boot at 3.2 and increase if need be...........

Cooling only modified by ICD on both the CPU and Northbridge and sitting atop my NC2000.
Prime95 x64 100% stable runs at small FTT
x12.0 3.200 GHz @ 1.1750 CPU = 69C TSZx= 79C @ 15 minutes
x12.5 3.325 GHz @ 1.2125 CPU = 72C TSZx= 82C @ 15 minutes
x13.0 3.458 GHz @ 1.2750 CPU = 85C TSZx= 94C @ 15 minutes
x13.5 3.600 GHz @ 1.3250 CPU = 90C TSZx= 100C @ 4 minutes in stopped to avoid shutdown

Edit; apparently the P7805's cooling system is not meant to handle this much CPU with these OC's

 

i;m quite sure it isn't... u might want to try the higher multiplier at lower voltage...sort of undervolting lol..

 

some guys can help me to set Vcore? I am using MSI gt729, QX9200 (ES@QAVS, E0 stepping).when I set Vcore = 1.275 with multiplier 10.5x, death blue screen appear. i tried many times but dump result. Or problem is at my 120W adapter (with ATI 4850 512Mb).Can you guys give me advice? Thxs

 

Have you tried first raising the vCore higher first then up the multiplier? After that start bringing it down to see where it becomes stable. If you do this keep an eye on core temps too. You don't want to cook the CPU or burn out the system. Just remember all systems and CPU's are different so some will run at lower settings than others.................

 

I can run at all settings lower voltages then I've listed and now use. With those settings Prime95x64 errors. Now everything else is flawless from what I can tell. Even CoresMark2010 runs flawlessly at 3.6 and 1.2750. CM2010 3.6 and 1.3000 seems to stay under 85C TSZx even at a 7-8 minute run (10x) so it is more than doable.

I am pretty sure I'll never stress the CPU to Prime95 levels with anything but other than 3.6 I know even at that level with my settings I am good to go for it all. I use 3.2 normally as I know the CPU should last and I'm not stressing the power board too much. I really want this to now last another 4-5 years.................

 

now i'm running prime95, 100% load CPU, temp max 89C, clock 2.66Ghz (10x266), Vcore 1.25. if I down Vcore to 1.2375, system is dump. how many Vcore can I set if i need multiplier 10.5x? Thxs!

 

Run at idle and right click TS and unlock max fid. I'd bump vcore to 1.3500 and try 10.5. To be truthfull if 89C now on Prime95 at 10.0x you most likely will overheat at 10.5x.

Anyway run prime95 and every 30 seconds drop vcore 1 step till you loose a worker to an error. Monitor the temps though as you will hit shutdown quickly. Exit Prime95 before that and let it cool then try and lower further on another run if you don't get the stopped worker. Once you have the stopped worker, exit Prime95 bump one on vcore and once cooled try prime95 again. exit well before you overheat though.

If you overheat before a 15 minute run thentry say Coresmark2010 and see if it will still run without overheating on 10x. If you can run that without issue you are probably safe running at the setting normally and may even find the setting that stopped a worker or even one below that can sustain the system under normal usage.

Just remember to stay away from running prime95 after that. It isn't so much the cpu's it is our cooling systems just can't handle the CPU heat output..................

 

I do step by step as you guide, 10.5x at Vcore drop to 1.3, prim95 runs for 3mins and temp up to 96C, hic. I think my QX9200 just stable at 2660Mhz, cannot up more. Thank you for detail guide!

 

Just DL'd the new ThrottleStop with the temp monitor in the side bar. I kept my old config file but I had to set DTSButton=0 as it was set to 1 and did not want to change.

 

Can you test that again TANWare? Once you have unzipped ThrottleStop into a separate folder, the DTS/Temp button should let you toggle the end column and it should automatically save your previous setting. If you close ThrottleStop when it is set to Temp, it should restart on Temp and the same thing when you have it set to DTS.

 

It hadn't before but I did not overwrite the config file, I'll try it from a different folder...

Edit; with the version I just DL'd it works now. it could have just been an older version that didn't work properly. Wierd though it wouldn't at first save the setting........

Edit2; I think I know the issue. The old version I know didn't save it. I copied from the zip all files minus the config but the config was open in notepad. Your code probably is not alowed to write to it then.............

 

I thinks your Edit2 is what happened. If the ThrottleStop.ini file is open in notepad then it probably didn't save the settings correctly. Either that or if you run it from a zip file then the settings might not have gotten saved either. Thanks for testing that. You can access 99% of the settings from the Options window so there won't be any need to edit the INI file anymore. Less chance of problems.

 

Right, that I this is what was up for the new version. The older version I had didn't seem to save DTS or temp setting but that was ok as it really meant nothing at the time.

Great little program so far, and thanks again..........

 

I'm sorry if this has already been addressed, I looked through the first five pages and if the answer was there I missed it.

I can't get a higher multiplier than x14 on my X9000, though I've overclocked in the BIOS to 3.0GHz. Why would this be?

Edit: I got an answer, I'd forgotten to unlock FID/VID. Also, I forgot to say thanks for such an awesome program!

 

Right click on the monitoring pane, and select Unlock Multiplier in ThrottleStop.

 

To my credit, I think I got that edit in before you posted again

Regardless, thank you once again. This might end up helping out a fair number of people who are facing slowdown in StarCraft II.

 

This program is amazing. I just got my x9100 and undervolted it last night. Today I downloaded throttle stop and punched the multiplier to 14x and it was past 4ghz. I just locked the core at the 4ghz and did some task and it's amazing how fast my computer was. I will run prime this weekend and see what I can get the max stable speed at.

 

wow u must have got a super one.. undervolt + ac = awesome.

 

He probably wasn't under volting and hitting 4.0 GHz at the same time. ThrottleStop is a miracle for Extreme CPUs but even it can only do so much. Great to hear about another success story. I originally thought that you must have an E0 stepping but then I read your sig and saw C0.

That CPU is definitely a keeper. It might be difficult to get it Prime stable at 4.0 GHz unless you have a meat locker handy but have fun trying.

 

Well I managed to play around with throttlestop and I'm currently stable @ 3.6GHz. Temps max at 84*C. I want to thank unclewebb for this again. Great software.

Btw, anyone with a 940xm @ 4.0ghz, what are your TDP and TDC settings?

 

There are quite a few users in the Alienware M17x-R2 thread that have done a lot of 920XM/940XM benching and should be able to answer your TDP/TDC questions. Generally speaking, they seem to be getting their best performance by dropping the peak multiplier down a couple of notches for less total MHz but then increasing the turbo TDP/TDC values to keep the CPU running at full speed on all 8 threads as much as possible. The multiplier reported in the ThrottleStop log file while benching should show you if you are maintaining the maximum multiplier or could use a little higher TDP/TDC setting.

Power = Voltage x Current

so if your core voltage is at 1.10 volts for example, use TDP and TDC settings based on that formula so neither TDP or TDC will limit getting full turbo boost.

A desktop 45nm Core i7 is usually set to 130 W / 110A so you're not likely to hurt your CPU by adjusting these but not all laptop motherboards or power adapters are going to be able to handle settings beyond 100 W.

 

Thanks unclewebb. I have my TDP to 70W and TDC to 60A currently, but I'll read around to find the best settings.
