i7 3740QM Overclocking guide

[Azther]

Found this picture quite some time ago on NBR and couldnt for the life of me remember who posted it, so posting this here for preservation sake.

I tested these settings myself on my M18X R2 with A11 unlocked bios with great success, However due to my single pipe heatsink my cpu was in the high 80s to low 90s depending on the load. So your mileage may vary depending on your setup, its no where near what the XM chips can achieve i know but at least its something considering i was under the impression these chips were completely locked down.

I had no idea the QM chips were able to overclock from the BIOS. Throttle stop did the trick back in the days. I have the tripple pipe heatsink in my 3720qm and I might try these settings and report back temps.

 

I upgraded to tripple pipe to be able to switch to an XM, but step back a bit, because our customs charges too much to have anything imported outside the EU.

yeah ive since also upgraded my heatsink, except i went with a dual pipe since triple is rare and hard to get ahold of. Now my cpu temps peak at 80-83c or so depending on load (the fan curve isnt as aggressive anymore compared to before, guessing it doesnt hit that temp threshold like it did with a single pipe to trigger the ramp up) , generally it hovers in the 70s when playing heavy games like cyberpunk (using Thermal Grizzly Kryonaut Extreme paste)

its sad that Intel does not allow those additional 4 OC bins anymore on non-K mobile chips. the recent trends are a bit worrying, even undervolting is being blocked nowadays, ugh...

but in any case, this same fact makes playing around with older gen hardware all the more fun. enjoy, guys 🙂

Just a follow up here, 

 

3920/3940/2960/2920xm are fully unlocked

 

3840/3820qm have 4 additional turbo bins, but is same true for 2860/2820qm? 
 

finally is 3740/3720qm 2 or 4 turbo bins? Same goes for 2760/2720qm?

sadly i cant really answer since im completely out of my depth when it comes to overclocking, turbo bins and whatnot. I just figured id try these settings out that someone on nbr mentioned years ago and it worked. The default settings on the 3740qm were 35,35,36,38 iirc if thats any help, the turbo limits were also adjusted

I set all the values 40-40-40-40 on my 3840 processor, it works stably, but it heats up and goes into throttling, as I understand it, you need to farm with cooling.

yeah mine goes to about 86c (hot weather peak, usually 83c or so)  now since i went dual heatpipe with kryonaut extreme thermal paste. used to be higher with single pipe

[DoenerBoy123]

I've done that with my 3840QM too. Hits around 90c under full load but is relatively stable and nearly always at 4GHz all core. If the CPU throttles, try to increase the long and short duration power limit. This might help, but i'm not sure about the longevity in terms of thermal stress for CPU and mainboard

What about the ram? Can Samsung PC3-12800 M471B1G73DB0-YK0 be overclocked to higher than 1600mhz? I tried but it keeps resetting to default

Also the flex vid overide I kicked up to 30

not really certain to be honest, ive always ran my hyperx kit at the default 1600mhz. I know theres 1866mhz of the same ram but i already had 3 sticks of 1600mhz left over from my old clevo so only had to buy 1 extra to fully kit out my restored R2 lol

Well I've got a i7 3740qm comming in from Australia, its in a m17xr4 with a 120Hz WideFHD (1920 x 1080)  screen, 32g ram, 2tb hdd, 500gb hdd, 60gb hdd and seller description "Nvidia Geforce GTX 680M. With TP esports gaming keyboard and mouse. Updated windows 10. Works good. Cant insert disc". I suspect "cant insert disc" means a dvd/hdd caddy. I mainly liked that it was Red, but the 120hz screen clinched it for me!

 So after i get it I'll spend time OCing the 3740qm after unlocking the bios, trying my gtx 1080 mxm that don't work, installing 500gb 850 evo, and my all copper triple pipe vapor chamber CPU heatsink. I really think I like tinkering these laptops than using them!LOL

Here is a link to Mr.Fox's OCing videos from 2013, he explains alot of the BIOS settings I found essential to know

OK if anyone is intrested, I got the m17x r4, i7- 3740qm, gtx 680m, 500 gb crusiall BX500 ssd,

ST2000LM003 HN-M201RAD HDD, LITEONIT LMT-64M3M and 120Hz WideFHD (1920 x 1080) WLED LCD w/3D Bundle

 Installed A11 unlocked Bios and set up overclocking the CPU all 3 settings gave me max 4.1 ghz

According to cpu world 3740qm = Maximum turbo frequency is 3.7 GHz / 3700 MHz so hitting 4.1 looks like max unless someone knows better HAHA
