3740QM Overclock?

I want my mobile CPU's clock speed to reach 4.0 GHz or get close to it, but spending 1k solely on CPU(3920XM) seems to be a huge waste. I did some research about 3740QM which has far more reasonable price than 3920XM, and people say it can overclock up to 3.9 GHz. Does anyone know if 3740QM is unlocked, and if it is not how do I do it?

Also would like a link to thread about 3740/3840QM OC if there is any.

 

well
i have a 3720QM
i overclocked it to about 4Ghz (see sign)
i used the intel extreme tuning utility
just make sure that in Bios>performance options>overclocking- is enabled

just be sure that overclocking can be very dangerous and harmful (to hardware and user) if done wrong

Happy overclocking!

 

I dont believe its dangerous, becuase the intel cpu's are limited to 55watt for a little time then going back to 45watts and then it will find its max watts.

So whatever you make, 4,1ghz, 3,5, 4,5 you will always have this limit of TPD

 

How do you get it up to 4 ghz? I know how to enable the over clock feature in the bios... But after that then what?

Just set up your BIOS like this, and it'll be overclocked.

 

Cool thanks I'm going to try that. I'd it safe? Wish I understood what all of it meant haha

Yeah it's relatively safe. Using the intel XTU just remember to stress test.

Mine currently goes to 4.1 GHZ when only one core is active.

 

Are those the same settings you use? The one sin the picture?

for 3840qm ?

 

It's the exact same procedure... You could maybe try to go 100 MHz higher first, see if it's stable, then another 100 MHz and so on. But the procedure for the 3740QM described in this thread also applies to 3840QM.

 

Hey guys,

I have a 3630qm and the overclock options are all grayed out in both Intel XTU and the bios. The setting for enable overclock is there - and when I set it to enabled - I cannot change any multiplier because extreme edition is grayed out.

And when I fire up XTU, I can change the bus frequency but I cannot change any multiplier...

Is it because of my specific CPU or am I missing something?

 

The 3630qm are locked down. You can not change the oc the turbo.

You have the entry level quad. Those are locked.

 

I just bought a Sager9150 from xoticpc w/3740qm...does the BIOS allow for overclocking? if not in the BIOS, can i use software?

 

U can use intel XTU though with the BIOS locked you'd be limited to 45W tdp I think. XTU might allow increasing the TDP. Not sure.
Download it and try it out!

 

I have a question

Why in overclocked mode the Graphic card parameters change and are worse ( orange box ) than on default mode ( yellow box ) ?

 

Guys please help me out..
i'm looking to but a sager np9370 ..everything is sorted out ..now all i want to knoe is..
3740qm on np9370 upgrade is worth 170$ at max TDP 45W
is it overclockable ..(400MHz) i heard .. it has HM77 chipset which is supported by INTEL XTU
i dont want to do the BIOS thing.... jist the XTU ?
will i be able to change only the multipliers using XTU with this processor on the mentioned system with the stock bios
if not.. is that easy to flash the modded bios coz i would really love to see it running at +400mhz
do reply people with some facts and experiences
i would love to hear positive responses ... and if not possible ..i'll be going for 3630qm that's stock...and i hope it won't bottleneck 680m sli
but still i would love to go for 3740qm if it does overclock a bit ...so help me out

 

i have another question... does the BIOS on np9370 support overclocking ?
i was thinking of upgrading to 3740qm due to its minore overclocking capabilities but only if it can be overclocked on this system...i don't want to spend 170$ for no reason.
it would be great if you could tell me if the BIOS supports changing the multipliers for 3740qm or the use of INTEL EXTREME TUNING UTILITY to overclock 3740qm on this system...

 

okok, Found out a little trick to trick the internals in a I7 or something, i don't know what's happening inside but here are my observations.

when you increase in Bus speed, also the TDP will get higher somehow.
I managed to get a stable 104.5MHZ and all my multipliers on 40, above this will get unstable, i need to increase Voltage but i wont.
Funny part is that the limit whent from 45watts to 47watts, so you get a real benefit instead of higher multiplier with same TDP (always stays on limit 45watts).
Also the 55Watts limit whent some higher to 57watts also but this is only short duration.

Maybe some other people want to expierence also with, it's real nice i got some real extra power out of it.

 

You need to read the P157EM thread here:

http://forum.notebookreview.com/sager-clevo-reviews-owners-lounges/681601-clevo-p157em.html

Since the P150EM does not support XTU by default.

@senshin

Even my (MSI 16F3) system has some TDP level control with the 3720qm and up though so I am surprised you don't.

 

I know what you mean, but!

The TDP will Always be capped on 45watts and 55watts, It doesnt matter how much your clockspeed is (multipliers), it will stay 45watts, you get my drift?
Your short power in a ivy bridge will always be 55 watts on max 56 sec. there is no way in changing this, then it always goes down to stay @ 45watts.
You can max the numbers to hold off some kind of throttling, but that's about it.

I can put it on 300watts (short power boost or what's it name is) but it will still be 45watts, these values you can change lower, but when changing higher nothing really much happens.
you can also see when stressing all cpu's it's getting stuck on let's 3.6ghz and 55watts, and it wont go higher in clock because it's lacks power.

Use a program to watch your TDP, like openhardwaremonitor, i don't care, Intel XTU.
Increase your Bus speed and you see what I mean, it's i geuss after all exploitation's the only way of "really" increasing your TDP.

Interesting, do you have a TDP_UP or config_TDP option in your bios? That's how I unlocked control in the bios in my machine.

 

hmm, I don't know really.

I could check it, just to know i am running a unlocked bios A11.

EDIT:
Check it but there is no option like it.
I can up the TDP to like 85 watts but you always get the cap off 45/55watts.

 

Hi,
for some reason this doesnt work for me.
Where yours says "Extreme Edition" - "Enabled" mine does only offer the option "BIOS"
Also, when I set the rest up just like in your picture CPU Z still gives me the usual info.
Furthermore, when I try to install the INTEL software it just keeps asking to restart my computer every time I run it.

Any help would be appreciated.

Cheers

 

Is this possible with the i7 2720QM. i'm using bio A.08 and looks nothing like yours? which bios are you using?

 

Apparently it is overclocking however CPU Z shows that the cpu clock keeps jumping from 1000 to 3900MHZ
which results in the benchmark score to be actually worse than without the overclock.
Any ideas?

cheers

 

Hi,

got myself a M17X R4
- CPU 3820QM
- unlocked A11 BIOS

But I can not change the BIOS-Option "Extreme" to enabled. It is greyed out.

Any advice for overclocking? How to overclock the 3820QM with XTU?

Cheers
