i7 3740QM Overclocking guide

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

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
