Lenovo ThinkPad T420 Cpu upgrade i7-2670QM 

How much of an increase was there? Was it noticeable?

the i7 is just 300mhz faster, its not noticiably faster

@@eltano06 The i5-2520 is a dual core with hyperthreading and 3MB cache vs. i7-2670qm which is a quad core with hyperthreading and 6MB cache. It's a noticable difference.

I found out that there was away to upgrade to cpu to i7-3632QM using coreboot (which lets you use ivy bridges)

how is the heat after upgrading the CPU?

Does the new processor i7 is rPGA-989 ? if so to what model it is ?

The original processor of this laptop runs at 35 watts and the Core i7 runs at 45 watts, how do you resolve that difference? Thanks for your opinions

@@vulcano911 I'm not a professional, and wasn't aware of this difference. Regardless, the upgrade just worked. I did notice the laptop ran at a higher temperature. This upgrade was 5 yrs ago. I gave it to a friend. and now I have a different laptop. Sorry, I can't answer your question.

Were you able to use the standard power brick?

In these trying times and you have the gaul to word a sentence as "Love the T-Series"? I urge you to take caution friend.

@@tallielintrasimpaccount Yeah, that could be taken out of context...

@Garrett Henson And subscribe to PewDiePie as well?

So easy, in fact, that I bought a second one. The extra weight (even worse: I bought 9-cell batteries for them) is WELL worth it. The obsessive documentation available (a legacy of the way IBM did things) is also IMMENSELY helpful.

I recommend using ARCTIC MX4 thermal paste!

@@Fatal1tyKillI used Artic MX-4, Clean all parts, coolers, cooling pipe (The cpu came clean o at least i though so), and my temps in a MSI CR643 goes from 40-50 idle to 92 under load, spring weather, 19.7ºC room temperature.

@@rociootondo1665 It could be the cpu or just not lucky

Try disabling Turbo Boost Also disable Meltdown and Spectre patches with InSpecte On my Ivybridge T430s with patches cpu temp was 70C at idle Without patche temperature dropped to 50C 20C drop in temps because of patches 🙄🙄

@@filipb.8698 can u share how to lower the temp of i7 2670qm? mine when gaming reaching 90c+. idle is 40-50c

How can you have 16gb? i mean, the i5 that comes with the Laptop only support 8gb

@@soyozzz mobile i5 Sandybridge cpus can support up to 16GB

@@soyozzz I also upgraded mine to 16GB RAM and 512GBSSD. I took out the DVD drive, put in a caddy and now use that slot for the HDD (as additional storage). The T420 is the ultimate laptop

@@ug1502ez Wow, i did not know that. Thanks for the information!!

I just upgraded the t420 ram to 16gb ddr3 1333mhz. Yes, it works.

You can get any ssd you want, but be careful when buying, some SSD are not supported on Lenovo Thinkpads. Before buying do some research! Did you check this cpu i7-740QM?

Fatal1tyKill great video! I have t410 as well and I’ve got the RAM 8GB and am planning on installing an i7 640m processor. I’m having a hard getting a straight answer on the t410- can it actually use a quad core i7?!? I’ve seen a few fail videos on RU-vid, and I have no intention of changing the motherboard. Also which brand of thermal paste did you use in this video? Thanks for making upgrade video!!

Grease quala put new thermal paste on the cpu

Clean the airflow, add newer thermal paste, make sure the room temperature is normal (room temperature can affect it) and buy some cooling pad

@@midnighteclipsed2738 nah it doesn’t matter the second gen intel CPU’s are incredibly hot, I used thermal grizzly on my i7-2670qm and that shit still hit 80 degrees just browsing the web, I even know of people who used liquid metal and it was still hot.

@@benchmarksx1650 so basiclly theres no solution? Isnt okay to use i7?

@@muhamadhamidi580 using Linux will hold the temps down a bit but once you start putting some work to it, it will kinda melt.

Where i can get 90watt adapter and larger battery

You forgot to mention expresscard slot, you can add egpu!

hey plz do a vido

Is it running libreboot and GNU Linux?

:)

the fuck you lookin at!?

​@@vulcano911you need the nvidia motherboard's heat sink

Bios update is needed

Yes it's a pretty good work computer.

next up I think you should upgrade the fan?

I did, but it was too expensive!

Here's the thing you need for video upgrade www.gearbest.com/laptop-accessories/pp_229102.html

No, you can't use 2 generation cpu on t410. ark.intel.com/products/43122/Intel-Core-i7-720QM-Processor-6M-Cache-1_60-GHz l ark.intel.com/products/47341/Intel-Core-i5-520M-Processor-3M-Cache-2_40-GHz

If you upgrade the cpu you need 90w power supply. !!!Make sure you have the correct model!!! Here's the bios update utility for Lenovo Thinkpad T420 support.lenovo.com/us/en/products/Laptops-and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T420/downloads/DS018785

I think I will try to update! I will vere such temperatures, but return to my i5. Anyway $ 100 for the i7 is very cheap, you could prove without losing anything in return. if I sell it not working properly xD Thanks for the quick reply! sorry for my english xDD is google!!!

I will make a video about the temperatures!

+Stef M Actually about t520, my boss owns one so we tested this i7-2670qm on his t520 and it has the same temps as t420. I'll will add aida64 test in my review. Thanks for the comment!

+Fatal1tyKill The devil is in the details. You see there are two versions of the T520 , one with the integrated intel HD3000 graphics , and one with the NVS4200m nvidia graphics using optimus technology. Lenovo only shipped the optimus version with a quad core cpu. Why? Because instead of a single heatpipe cooler (same as the T420), it comes with two-heatpipe cooler which is beefier. So only the T520 with NVS4200m is actually meant to use a quad core cpu. In any case I will subscribe to your channel to watch the aida burn in-test. I always enjoy thinkpad videos. Good day.

I will try to talk about all of that as much as I can!

I know the best laptop for work!

Like I promised, just ugraded my CPU.I now own the most powerfull t420 ever :). I think 32 GB would be overkill. I am going to stick with 16gb for a while and see how it behaves. Specs Intel Core i7 2670QM, 16gb Ram 275 SSd and 1TB Physical Hard Disk, 1600by 900. Extended battery

Nothing is overkill!

how is everything now? i have a t420 too and i want to upgrade it for video editing purposes. is there any problems to be concerned about with heat... or anything ?

Space Raanger hi, nope, I swear it even runs cooler with the i7. It could be because I replaced the thermal paste (hadn't done so with the i5) but generally it's all good. Much faster and cooler so go for it. I also recommend you get the SSD for the best performance.

It should work, but I'm not sure about the temperature and performance.

Cpt MishMash VonRandom any chance u upgrade to i7-2860QM? If so any overheating problems?

Hi, I did indeed. It actually doesn't get nearly as hot as I expected it might. I did mod the heat-sink a little beforehand, but I'm not sure just how much that actually contributes. I use the computer for android development and where my stock X220 and X230 get up to temperatures of around 75/80 on heavy load when running Android Studio, gradle builder and the AVD, the T420 stays happily around 5-10 degrees less than that. I had previously rebuilt the computer and given it a thorough cleaning, particularly the fan, spindle etc. I'm looking into possible upgrades for the fan next. Something with a higher RPM or better designed cooling fins maybe. I don't have the dedicated graphics on mine so there's a spot beside the processor where the GPU would sit. I've been thinking about adding more heat pipes that extend towards this area and help to transfer heat faster than the standard setup.

Nice

+Leon Petrić (ToTheSun) Will do!

www.gearbest.com/laptop-accessories/pp_229102.html This is what you need!

Awesome bro! :D thanks again :D!!!

Battery life around 3.5 hours and you need to install the latest bios.

Oh my. Alright haha, thank you.

You can

Definitely the way to go swapping to an i7 2640M from the i5 2520M Had zero issues!!

No you can't replace the cpu on T420s.

Oh. I haven't been able to look up much information no the T420s so I was unable to find anything on upgrading it. Thanks a lot.

Latest BIOS

But first make sure your bios is up to date!

Don't forget that you need 90w 20v ac adapter. Here's the link to ebay www.ebay.com/sch/i.html?_odkw=Original+lenovo+t420+ac+adapter&_sop=15&LH_BIN=1&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.XOriginal+lenovo+t420+ac+adapter+90w.TRS0&_nkw=Original+lenovo+t420+ac+adapter+90w&_sacat=0

Yeah, I actully watched your video dude. I also ordered an ac adapter. Still waiting for the stuff to arrive though.

That's great!

Okey so I managed to upgrade the processor now. The computer runs and reconices the processor. There are though 2 screws left which I don't remember where they went....

I would like to, but I don't have 900p or a 1080p screen

I can send you the specific part number for a compatible screen if you want

ThreeHeadedWalrus I don't have screens like that laying around work, sadly enough :(

It's working perfectly fine I used at work no problems!

thats not true, i had with intel chip and i could connect up to 3 screens, VGA; DisplayPort and HDMI .

The one with the NVIDIA chip has both the NVIDIA chip and the intel graphics. If you could connect 3 screens and have them all running at the same time, then you had to have the motherboard with both the NVIDIA and intel graphics cards. The intel chip supports only two monitors at a time.

dullgeek how to fix it on the laptop

forum.notebookreview.com/threads/t420-upgrade-to-i7-2720qm-es-q154-successful.624256/

I know!

just sayin \

I have the exact same one but with i7 from Lenovo. I ordered the i5 one of some guy of eBay I actually got i7 one I bought second one after that with same reseller [He had 2 of these for sale] Same story got the i7 one with correct powerbrick. Those things even had 8GB of ram which for a € 220 Laptop is darn good. Most important they both came with NVIDIA chipset also not expected. Only downside is they came with painfully slow HDD's of 160GB & 320GB Replaced them with spare HDD's but will get SSD's [hopefully] soon. Quick tip for the ones that read all the way through: You are able to use an External GPU with this laptop [With external i mean Full Size Desktop Class GPU example : GTX980 even 1080 would be possible but a bit overkill] I tried it and actually CPU holds up pretty well. If anyone is interested search for EXP GDC Beast [Express Card Version] I got mine from banggood [They are available on other sites but i know BG so went with them] Just takes a while to get fully up & running. [Express Card is right above SD Card slot on the right side] Not trying to advertise but alot of people do not know that this is possible. [If requested i can remove this so Fatal1tyKill just tell me and i'll edit this out or the site name!]

It's ok ark.intel.com/products/53469/Intel-Core-i7-2670QM-Processor-6M-Cache-up-to-3_10-GHz

It's totally ok coz all chips with bga solder no problems during soldering process in 300°c temperature

MRWOLFIE8788 You can technically go as far as the 3840qm although you need to use coreboot. I’ve just ordered a i7-2820qm for my T420, which is essentially a straight swap.

The real pro about the 2nd gen is the idle frequency, much lower than 3rd gen, while it stays on 1197MHz i5 and i5 both :( btw did you do a stress test on aida64 with gpu also to see real temps?

Both of the CPU's are good choice, the temps should be ok. Intel HD 4000 support directx 11 so you should be good! Here's a video for i7 3612QM: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E-Xe8EP_grs.html

Do you keep turbo boost on or not? Don't know if buy higher base clock i7 and disable turbo boost, or low base clock i7 with turbo enabled. What's your suggestion for best battery lif end temperature? btw it's a totally different pc and mainboard to have a comparison :/

I turned off the turbo boost, lower temps. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0GiF1rrWK7U.html

Thanks :)

It's an express card slot, you can user it for this www.ebay.com/itm/V8-0-EXP-GDC-Beast-Laptop-External-Independent-Video-Card-Dock-For-PCI-E-X16-/401280185129?var=&epid=2129003187&hash=item5d6e29b329:g:MscAAOSwkr5ZkqXa

You need to download the latest bios for your Lenovo T420!

I'm not sure if you can upgrade the cpu to i7-3630QM in the Thinkpad E430. You don't need custom bios, just the latest bios on the official website. Cpu upgrades on laptop are always risky, sometimes it doesn't work. I couldn't find anything on forums about this upgrade. I think this idea requires testing. I hope this helps. Forgot to mention, the official website says there's a Thinkpad E430 with i7-3612QM. support.lenovo.com/lt/en/solutions/pd024708

Thanks for your opinion.

No problem

The GPU is integrated!

@@Fatal1tyKill i've read somewhere on the net that upgrading the cpu will automatically upgrade the gpu coz yeah it's integrated with the cpu, so could this be true ? btw thanks for the quick answer brother

GPU will stay the same.

Probably not. Here's the requirements lumion3d.com/system-requirements.html

@@junkies4463 That's 3gen CPU, you need 2 gen CPU

@@Fatal1tyKill that means only 2 gen CPU is suit for it? thanks mate i was consider to buy X230 but read some article the cpu not upgradable based on BGA socket. So i will consider to choose X220

i7-2670QM is powerful, i7-2860QM could work too. I would look around forums or reddit for a better answer.

L H the charger should cost 20-30$, cheaper adapter is made from cheaper components which means it could damage the laptop

I recommend getting 90w adapter!

Thanks.

Could you just tell me how much dd you pay the processor? I watched the prices but 500$ plus....thats a bit to much....thanks ;)
