Replacing the CPU on these machines is certainly possible, as they are socketed, but in the case of the T410, you have to disassemble a good amount of the system to get access to the CPU. Check the T410 Hardware Maintenance Manual by clicking on the HMM link at the top of the forum.
With that said, if your has a reasonably fast i5, replacing it with i7 will not make a meaningful difference whatsoever, but the machine may run hotter.
X61 7673-V2V, T60 2007-QPG, T42 2373-F7G, X32 (IPS Screen), A31p w/ Ultrabay Numpad, A21m 2628-GXU
allready maxed out the RAM to 2X4GB, and using 180GB Intel SSD in main bay + 500GB Seagate HDD in the ultrabay.
Took my time installing it today, and I can definitely notice the difference. To say it gave my old T410 new life would be an understatement.
The closest comparison I can think of would be like swapping a two-barrel carburetor for a four barrel on a four wheeler. If you think that comparison makes me an old fart-actually I resemble that remark.
Wish I had done it sooner, have had a Samsung 840 Pro SSD and maxed RAM for a few years. Too bad the MB is only SATA II. Kudos to whomever put the HMM's on the forum.
Here are my tips which may help others:-
The best thermal paste is Thermal Grizzly Kkryonaut. Saw 2-3C lower temps compared with MX2 or MX4 and 10-15C lower than the original aged paste (tested on i5-520M – stock this would hit 95C with Prime95)
With the i7-640M upgrade, I also tried the dual-pipe heatsink but it was slightly worse than the fatter-single-pipe heat sink by 2-5C (others say the opposite but I suggest they are mainly seeing the improvement of fresh thermal paste?). Plus, the fan on the single pipe heat sink has a more pleasant sound. When running Prime95 small FFTs on 4 threads, and combing the single-pipe heatsink with Kkryonaut paste, the CPU temp holds steady at 78C for 20-30 mins, the fan is maxed at 4600rpm and with an ambient temp of 22C. In normal use, the fan never runs at max speed unless all four threads are fully loaded for more than 6 minutes.
The SATA-2 limitation is less noticeable than benchmarks show. I use a Samsung 2.5” 860 EVO SSD with the Magician RAPID mode enabled, this gives a good uplift across the board, and especially sequential I/O, to not miss SATA-3. Also, the standard Windows 10 SATA driver works far better than any of the old Intel SATA drivers (greater throughput and less hesitations under load)! This T410 will cold boot in 18 seconds to the Windows 10 sign-in screen.
The Intel turbo boost driver is needed to achieve maximum boost, the standard Windows 10 driver does not fully boost and also shows slower graphics/FPS in tests.
Also upgraded to 8GB but not seeing the expected benefit of dual channel RAM, so anyone out there with some tips please let me know. The RAM bandwidth does not double up, why?
