Thinkpad T420 and I7 3840QM
Thinkpad T420 and I7 3840QM
Hello! I'd like to know, if i mod the bios of my T420, will it be able to take the i7 3840QM Ivy Bridge CPU ? I can get it for pretty cheap if it could work.

I tried the CPU. Turned on, some LEDs lit up, but no display.RealBlackStuff wrote: ↑Mon May 28, 2018 9:50 amWelcome to the Forum.

Rephrase the question to Sandy bridge quad (Core i7-2820QM) for T420 and see what answers says?

Re: Thinkpad T420 and I7 3840QM
Did you apply Coreboot first?
Re: Thinkpad T420 and I7 3840QM
No, im just asking will it work, cause i've only seen people try the I7 36xx and 37xx, not 38xx. yes, i have tried to search for the 3840QM
Re: Thinkpad T420 and I7 3840QM
The T430 has seen 3840QM mods tho.

If you have coreboot , the machine will run with the 3840QM. But, I'm not sure if it will overheat. My 3630QM does not overheat but it may throttle, cpu temps reach 90C under extended load, >20minutes.
