How to Unlock the Core 2 Extreme Multiplier in Windows

Well I tried that but since I have a B1 version ES processor the temps are not displayed properly also I tried 3.6ghz and it resulted on a nice BSOD. lol

 

MexicanSnake: A BSOD is a CPU calling out for help.

"Give me some more voltage."

 

But of course, be smart when you pump your voltage. Granted, I've a 4GHz X9000 with 1.5v but I don't run it at that voltage - It's currently clocked to 3.6Ghz @ 1.3625v maximum. It's just to show what's the highest it can achieve stably.

 

Yea I was thinking the same thing, it must have been with the 120w adapter, which is a joke considering its quite easy to exceed that with the 920xm and 5870m in the system. I'm using the 180w adapter, i shouldn't run into any problems.

 

Thanks guys for your responses I really appreciate it!!!

Yep lol nice idea,Ill try a higher voltage muuhahahha perhaps 1.36 volts ?

Is just that I dont want to fry the laptop... Im about to sell it hahahha

Edit: Just hit 3.8ghz @ 1.42volts lol

 

Good work. You just increased the value of your laptop. Buyers will be willing to pay extra for that kind of performance.

3.6 GHz should be a very safe 24/7 setting.

 

I needed 1.475Volts for my X9000 to let it run stable @ 3.8GHz.
My CPU seems to be very power hungry. So I had just 2 VID steps left for running stable @ 4.0 GHz. 1.5Volts is the max I can feed and isn't enough for my CPU to be stable. Shame...

 

Can I ask how the heck you people are keeping these CPU's cool enough to pump over 1.3v into them? It doesn't take much over stock voltages (under 1.2v) to get my temps up to 95c+ in stress tests and the W90 was always said to have a decent cooling system... Running AS5 of course.

That's all that's limiting my overclock is cooling potential. Intel recommended Vmax of 1.175v at 3.35ghz and I'm heatcapped -.-

And to the poster above, when the CPU starts taking more voltage for less of a mhz gain, stop.

 

At 1.3625v 3.6GHz, mine runs 75*C maxed for 4 hours doing 3Ds Max rendering @ 100% CPU usage with no coolers or air-conditioning. It all depends on the cooling capabilities - the heatsink and heat transfer efficiency in general. And it's also highly CPU dependent.

By default without undervolting, 3.4GHz is the highest overclock provided by the M1730 BIOS running at 1.425v, and 1.2625v on 2.8GHz stock. With undervolting however, it's a "swap" over; running 1.2625v on a 3.4GHz overclock, stable and 60*C maxed.

3.8GHz @ 1.450v gives me 85 - 90*C maxed for 3 hours 100% CPU usage. If I ever run at that voltage and speed for long periods of time, a heatsink mod is needed. In which I finished planning and about to start soon...

@ MexicanSnake, I know as I said earlier, a CPU's UV'ing capabilities is highly CPU dependent, but 1.425v at 3.8GHz is a little bit low especially for an E0 stepping processor. I got a BSOD after 2 hours on 1.425v, 3.8GHz. Sometimes a BSOD can pop up when you least thought it was stable; may I suggest, running Prime 95 for at least half an hour or more to determine its real maximum stability. Watch your temps, you must.

 

I reckon with proper cooling my x9100 could hit 3.8-4ghz at 1.4-1.42v

 

Yeah I'm planning on adding a desktop HS to this notebook for kicks to see what I can push out of her but man this CPU pumps out a ton of heat.

 

My QX9200 cost me $183 and now OCed to 4009MHz(365x11,IDA mode) in the everst

but no way to keep it there

(stable in 3.33GHz for gaming)

and i felt it worth the money

Thanks! Ill try wprime now! I know sometimes BSODS can appear if you are Ocing. My temps are just fine . I made a heatsink mod and applied ICD7 karat 24 hehehe and other thermodynamics tricks .

Mmm maybe it depends on each processor I heard somewere that every cpu is different from another and even if they are the same model some can have different temps... Perhaps Im lucky

And thats thanks to you! Yeah Ill post that Im sure that my buyers will like that, yep I better keep it @ 3.6ghz, since I want lower temps...

But since I have modded my laptop with some thermodynamic tricks then temps wont be a problem at all.

My max cpu temp @ full demand is 78C @ 3.6ghz, which is fine .

 

I tried running Prime95 Small FFTs at stock 9.5 multi in performance mode with stock VID of 1.125 until temps stabilized at 73'c. With Cpuz, Hwmonitor and Throttlestop running I slowly stepped up the Vid all the way to 1.300 with no increase in temps. All monitors showing increase in VID but no temp increase. I guess the motherboard is not allowing VID increase, unless its tied into the multiplier. Hwmonitor shows that in IDA mode of 10.5 multi that VID is set to 1.237 at 2800mhz for my OEM Qx9300.
No matter what I try I can only get up to about 3000mhz stable. Some have achieved much more of a o/c with the Qx9300 in a W90vp so It must be my chip. Anyways I have ordered a Q9200 from uk to compare the two so I will maybe know something more then. Thanks unclewebb for all your work and knowledge and sharing it with the rest of us.

 

Cygnus X-1: The VID setting is a requested voltage but I know some motherboards ignore this request. I have an Asus desktop P5B Deluxe that ignores this request as soon as you adjust the voltage setting off of the AUTO setting in the bios. I have no idea what voltage settings are available to you in the bios. Many laptops don't have any settings like this.

If your motherboard does not allow you to adjust the voltage and it ignores the VID request register then you are going to be limited in your overclock no matter what CPU you use.

If the Q9200 has a higher default voltage then you might be able to overclock a tiny bit more but it will probably top out at about the same MHz.

Check out the bios and let me know if you find anything hiding in there that fixes this problem you are having.

Edit: HWiNFO32 will show you your 4 VID settings for SLFM, LFM, HFM and IDA.

 

Does anybody know if Throttlestop's multiplier and voltage functionality works with the Asus G50v(t) laptop? The multiplier is locked through the BIOS.

 

You should be able to adjust the multiplier without any problems. It would be a good idea to ask this question in the Asus G50v forum

 

Thank you very much unclewebb for this great tool working good on my asus w90

Is 3.7GHZ 100% stable? That is insane for a quad core Penryn imo. I suppose that means that the X9100 has even more potential.
Good times!

 

If you think 3.7 GHz is insane for a QX9300, check out what scook9 has his QX9300 running at.

http://forum.notebookreview.com/6453919-post3737.html

4166 MHz. Now that's insane.

Marc_: I think scook9 had to max out the VID at 1.500 for those runs. I don't recommend that but it's always nice just to see what one of these CPUs is capable of. 3.7 GHz with a VID of only 1.350 volts is excellent and in my opinion is fine for 24/7 use as long as it is stable.

If you want ThrottleStop to be able to monitor and log CPU and GPU temperatures just add this to the ThrottleStop.ini configuration file for your laptop.

TJMax=100
GPU=2

 

quad core 4166 MHz with 1.5v VID ..............Orz...

Is there anyone know the Max FQ and VID for a ES version Core 2 Extreme 2.40GHz for the 24/7 use?

thanks..

 

It's processor dependent. Some processors of the same type cannot be overclocked as high as 1000-1200Mhz increase, while some will need more voltage to achieve the same overclock than others of the same type and speed. You need to test it yourself to find out your processor's maximum stability and its voltage minimum.

I have a friend's QX9300 going above 4.5GHz 266x17 1.400v stable, but bricked when it reached 5GHz, 1.5v... What a waste.

 

I can't overclock anymore with my QX9100...

I could at one time (few days ago) pump the multiplier up to 11.5x (3ghz) on my Q9100 ES and ever drop voltage a bit and be completely stable using the newest version of TS.

My PC crashed when gaming (video card issue, need to RMA) and when I rebooted TS no longer works...like, itll overclock, but be stable for only a second before the laptop crashes...no matter the multi or voltage...and Im pretty sure the CPU is OK as its running fine at stock speeds now and passes stressing. SetFSB can overclock to about 2.5ghz...but that doesnt adjust multiplier nor do I want to use it haha...

So...CPU is good...overclocked before no issues...now won't overclock at all, no matter what I do.

Advice?

 

probs with 2.74 keeps rebooting during benchy so went back to 2.55 an all good again > both vers set on x20, 1.4250v, Perf1

 

I'm using ThrottleStop 2.74 on a QX9650 desktop and a T8100 laptop and haven't noticed any issues with it yet.

If you are having a problem and want to go back to an older version then you can try downloading this one.

ThrottleStop 2.55
http://www.mediafire.com/?zzmn0wwzktz

 

Just thought I'd let you know your mediafire link is dead.

Oh and I'm about to try 2.74 on a HDX Dragon with a x9000

EDIT: scared the crap outta myself there for a sec, pushed it too far and was gettin BSOD every time I tried to boot into normal windows mode. Only way to fix it was restore bios defaults

had it at x20 with a voltage of 1.35, which made it 3.9ghz

I've left the voltage the same but turned it down to x18, at 3.6 now

 

I just clicked on the Mediafire link for 2.55 and it worked for me. MediaFire is usually pretty reliable.

It can be dangerous to try to go too high with the MHz without having enough voltage to support that frequency. Keep in mind that the setting in ThrottleStop is a VID setting. Due to vdroop, actual core voltage on many motherboards might be 0.050 volts less than the requested VID setting. Trying to use only 1.300 volts for 4.0 GHz might not be enough and you can nuke your Windows installation when you try to do stuff like this.

It's better to go up slowly with the multiplier and thoroughly test each step. ThrottleStop makes it easy to see what she'll do and how fast you can push it but it makes a lot more sense to only go up to a higher level if the current level you are at is 100% stable. If not, you're asking for trouble.

 

Cool man thanks, it's just that was the first sign it showed up being unstable, temps were fine, just splatted out on me all of a sudden. What sort of voltage do you recommend for my set up?

 

advice to anyone never OCed there x9000 an thinking to try X16 (3.2 GHz) is could try starting on 1.3000v stress test with program like orthos beta for about 2 hours while running a temp monitor along side > if concerned cpu temps to high stop!!!!! let us know please because your fans may not be coming on higher speed to cool down cpu. but if okay drop down to 1.2875v an try again keep doing this one step at a time until get BSOD and then raise 0.0375v or 0.0500v(3 or 4 steps up) an test again if okay your done...had a few BSOD like this
Take Special note what uncleweb says about very low voltage on a high multiplier can lead to disaster , an way to high voltage on a low multiplier cant be good either

dells 4 settings for XPSM1730 With Extreme which are only cpu's able to unlock DELLS OC tool in BIOS
set Bios to each multiplier an RM-Clock to find default VID's for X9000(non-ES), No TStop

x14 = 2.8GHz > default 1.2000v > fans operate related to temps (controlled by dell) > (Bios default)
x15 = 3.0Ghz > default 1.3625v > fans operate related to temps (controlled by dell)
x16 = 3.2GHz > default 1.4125v > fans switch on 100% max speed continously regardless ot temps(controlled by dell)
x17 = 3.4GHz > default 1.4625v > fans switch on 100% max speed continously regardless ot temps(controlled by dell)

from x15 to x17 VID to high!!!!
most of the time run on 3.2GHz 1.2375v with RM-clock an never had issue... until annoying dust built up in me rig few months ago...well use TS now to undervolt @1.2375v 3.2 bios is set to 3.2 to switch on fans 100%

only run high cpu clks just for impressive benchys an able because of excellent cooling + inside notebook heatsinks an heatsink fins clean from killer dust + clean os installation with minimal drivers installed just enough to run benchies.

starting to suspect NSPT on high gpu clks somehow gets corrupted causing issue to TS on x20 or x21
reinstalled NSPT 2 times to fix (running on 32xp). well what do you expect running that high a gold medal, no way run full time on x20 thatz insane

 

HWiNFO32 is a useful program for showing you the default VID settings your CPU is set to.

HWiNFO & HWiNFO32 - Hardware Information and Analysis Tools

It shows the SLFM, LFM, HFM and IDA VID values if your CPU supports all of those settings.

hikkoo: Does your XPS M1730 ever have any clock modulation throttling problems like many of the Dells do? How many watts DC is your power adapter rated at? That's a nice 3DMark06 score in your sig.

This only happened to me once in my life where not enough voltage resulted in XP getting so screwed up it wouldn't boot. After wasting too many hours trying to fix it, I finally gave up and had to do a re-install. That's when you learn how much stuff you haven't backed up recently.

I find it's better to start with a little too much voltage and work your way down if you are stable rather than try a high MHz without enough voltage.

 

How's 920XM progress coming along?

Also, I know it's not possible now but in theory could the multipliers be separated? +4x for single and dual core, but only +2x for 4 cores?

 

This is probably going to sound dumb but ThrottleStop performs some magic on the 920XM and 940XM but I'm not quite sure what it does or what the advantages and disadvantages are. The Intel documentation leaves out more than it includes so I'm a little in the dark too. I think users are mostly using ThrottleStop's ability to adjust the TDP/TDC turbo power limits and aren't using its ability to adjust the turbo multipliers that much due to heat and power constraints.

I haven't seen much testing or gotten much feedback or test data of these new features and I don't own any Core i7-XM hardware so I'll have to keep searching through various forums to see what I can learn about this.

 

tried Core Temp 0.99.5 an latest hwinfo32 beta give exact same default VIDs in previous post. uncle maybe who ever set default VIDs for multipliers x15 to x17 at factory had little knowledge correct relationship multiplier to VID or they didnt bother doing thorough stress testing.


about clk modulation....crap stuffed up bad... ran again wPrime 1024m v1.55 with TS open x19 1.3875v Perf1 ..... drops to 87.5% for 1 sec then back to 100% for about 15 secs, cycles.....score 713.923 sec..... SORRY me fault didnt run long enough starts happening about 40% into run... . Then ticked clk mod @ 100% X19 1.3875v along side benchy an scored 674.159 sec ..Woow!! never dropped below 100% when clk mod ticked using TS 2.55
looks like need to redo benchys, lets see if we can break 18k


Anyone deciding to use wPrime v1.55, Remember to click Advanced Settings > change Thread Count to "2" for x9000 or dual core > save > run 1024M benchmark to test for clock modulation throttling

 

With a Dell laptop, you have to be really careful that you are not pushing things too far and triggering clock modulation throttling. That can really kill performance. It's good to hear that ThrottleStop is working to fix that problem. Some of the newer bios versions on other Dells like the XPS 1645 are so aggressive that ThrottleStop is not nearly as effective as it originally was. I know what Dell is up to and now they know what ThrottleStop is up to so they've come up with some more aggressive throttling schemes.

Your 230 watt power adapter looks good. That's a lot better than the pathetic 90 watt adapter that Dell originally shipped with the Core i7 XPS 1645 laptops.

 

hi,could you support ES(not Extreme) CPU, unlock the multiplier?

 

Can you post a screen shot of CPU-Z so I can see what CPU you are using. Either that or send me a PM message with that information.

There is already a secret option in ThrottleStop for Core 2 ES CPUs. Try adding this to the ThrottleStop.ini configuration file.

Extreme=1

Hope it works.

This option is only designed for CPUs that have adjustable multipliers. If your CPU does not have an adjustable multiplier then this option won't do anything and might cause problems. Just right click on ThrottleStop to see if any new menu options pop up like in the first post.

 

thanks.
I use T4500 QMLH ES.
Add Extreme=1 in the ThrottleStop.ini file,there is "unclock max FID/VID"in right click menu,click.But the multiplier can't set higher from 11.5(default).click turn off shows a message ,ask me to turn on.So I turn on,but still can't get higher multiplier.

 

Here's what the first paragraph says in this thread.

This feature is only for Core 2 Extreme CPUs. A T4500 is not an Extreme CPU. Most Intel CPUs have a locked multiplier so they can not be adjusted higher than the maximum default multiplier. Trade your CPU for an Extreme X9000 and then you can unlock your CPU multiplier and overclock it much higher.

 

So the C2D mobile es version doesn't have an unlocked multiplier

 

No they don't.

 

From my thread here:
http://forum.notebookreview.com/har...-wont-overclock-anymore-help.html#post6544057

Trying to figure out the issue...

 

Some ES processors might be unlocked but most ES processors have the multiplier locked just like any other non-Extreme Intel CPU.

 

If you are replying to my post above...my ES has an unlocked multiplier.

 

Brain dead post corrected.

 

Huh? The T4500 is someone elses CPU a page back or something...I have a Q9100 ES with an unlocked multiplier. You've responded to my thread

 

Ooops, went brain dead for a moment.

I thought lmkong was still trying to tell me his T4500 has an unlocked multiplier. I'll go fix that post up.

 

I finally got my X9000. Thank you again UncleWebb for Throttle stop. Dual IDA was nice, but the unlocked multiplier control is just awesome!

Things are a bit toasty though. 3200 MHZ is great at default 1.2v, but 3400 MHZ requires 1.25v for me and its 90-95C w/my laptop cooler. Not bad though for a Dell D630.

 

You're welcome MaxGeek. I have a similar D830 that could use an X9000. The CPU/GPU cooling solution seems pretty good on this laptop. What sort of programs are you running to hit over 90C? An X25-M makes this laptop very usable but a 50% boost in MHz would really make it shine.

 

Only stability test make it go that high.
I ran Prime95 & a 1080p HD video at the same time for 30 mins to make sure I had enough voltage for stability and enough cooling power to keep it from throttling down.

I mainly use this machine for development work so it won't get taxed like that regularly.

I went for 3.6GHZ, but even at 1.3v it wasn't going to happen.

 

Looks like the D630 can't do more than 1.3v. I tried it up against my ac and it was 25C cooler at load. 3600MHZ worked like this at 1.3v, but obviously I won't be able to have it attached to a AC unit.
