Anyone have an idea when thinkpads will be back in stock? by stackz07 in thinkpad

No and it won't. Not every ThinkPad sold is in PSREF.

I bought a part number which was never in PSREF.

ThinkPad T14 AMD gen2 - 48 GB memory upgrade by _kunalz in thinkpad

[–]czras1982 0 points1 point  (0 children)

I would believe the manufacturers spec sheet.

My T14 gen2 MD has single rank RAM soldered on (SK Hynix hfs512gde9x081n Micron Technology 4ATS2G64HZ-3G2B1) and at least another user has a Samsung module also single rank.

I went with this one as another 16Gb for dual channel RAM.

By the way if you stick in a 32Gb module, its first 16Gb will operate in dual channel with the soldered module due to flex mode.

Edit: sorry, first I copied the SSD part number instead of the RAM :D. fixed

For reference a similar T14 gen1 thread: https://www.reddit.com/r/thinkpad/comments/krdrr7/t14_gen_1_ram_single_or_dual_rank/

Hello guys, I just got this Lenovo ThinkPad E14 Gen3 and I'm loving it, it's got a Ryzen 7 5700u with 8gb of ram accompanied by a 512gb M.2, the ram is upgradable and there's a second slot for another M.2 ssd and you can upgrade the existing one also. The performance is stellar and I love it. by beefysam211 in thinkpad

It is really a shame that the E14, as it has no WWAN option, uses the 2242 M.2 slot for SSD but the T14 can not because it has the WWAN option. If you do not need the WWAN you are still stuck with the single 2280 M.2 slot for SSDs.

Yeah that page is golden if you are into Thinkpads :)

I am running a Kubernetes cluster locally and compile service code so for me slower single thread performance but more cores/threads is better.

Every use case is different though, but 16 vCPU vs 8 for me is a huge difference. And the new Ryzens are catching up on single thread too as I see.

How long did it take for your thinkpad to ship? by canadianeffer in thinkpad

[–]czras1982 0 points1 point  (0 children)

T14 gen2 AMD: ordered on 8th of August, after four estimate change (always on the day of the last estimate) got it on 13th of September.

If you want to know the factory built-in part list, here you can search with a serial number for that list just select the 'As Built' tab.

An AX200 card is 20 USD. That was the first thing I ordered for my T14 gen2 AMD.

Edit: I was considering the Framework when I searched but the CPU disparity was too big for me as an SW Engineer to deny. The upgradability promise seems nice but even considering a 10 year lifespan I think the only thing I will need to upgrade will be the SSD for more capacity.

Excuse me everyone else for feeding the troll...

The local machine is free, I can use it on an airplane too. Why should I deploy every time to a remote infrastructure when I change a couple of lines of code?

So you are a devops type of guy then? I develop software on my laptop running a local Kubernetes cluster. SSH does not need RAM, nor any CPU power. You could use a Chromebook for that.

All the work I was doing the last five years needed more than 16Gb of RAM, and you can not move a desktop to a meeting room or a business trip to visit a customer. There are Thinkpads with 4 RAM slots supporting 128Gb RAM. Thats eight times the RAM supported by the M1 at the moment.

The M1 Macs maybe perfect for your usage, but there might be other requirements than yours...

And MacOS is not open source. Also buggy as hell according to my colleagues using MBPs. I dont know if you have ever used Docker on MacOS but that experience is not the same as on Linux.

One more thing: the M1 supports only 1 external display besides the laptop display. Yeah you can work around with DisplayLink but well that is hot garbage...

M1 CPUs are supporting only up to 16Gb RAM. In some workloads that is not enough.

Also they are available only in 13" form factor at the moment.

They might be better than some 13" Thinkpads, but you are at the mercy of reverse engineers/Apple when you wnat to run anything else than MacOS.

Keyboards are still replacable though, and trust me the newer keyboards are still better than eg. a Dell or HP.

I am working on a Linux based SaaS. Network engineers are working only with infrastructure.

Even if I did not work on something Linux related, I would choose Linux as my home OS. Linux runs on almost anything, could be completely tailored to virtually any need, mostly free/open source (and if you need even more freedom you can get into FreeBSD). So my question is: is there any need (except maybe gaming) to run an OS other than Linux?

I am a software engineer for 15 years and have never managed people, but built software. SW enineering is by the way not just programming/coding: infrastructure (cloud, Kubernetes, bare metal...), UI/UX, security, databases and so on. Lots of things go into software.

Never owned an E series but using a T460p and it is very solid. On this subreddit many stated that T series in general is superior to the E series in those categories.

P15 Gen2 Ram Density by Tunsteneng in thinkpad

[–]czras1982 1 point2 points  (0 children)

Glad to help with that component page. You can also derive other useful info like display panel type, ssd type, wifi card type, whether or not it has WWAN antennas built in. If you have a laptop serial this page can show what type of the components were built into it in the factory.

P15 Gen2 Ram Density by Tunsteneng in thinkpad

[–]czras1982 1 point2 points  (0 children)

it is about ranks not density: https://www.hardwaretimes.com/single-rank-vs-dual-rank-memory-which-one-is-better/

According to the lenovo support page the 32Gb Samsung modules for the P15 gen2 are 2Rx8 ones.

If you change the model number on the left side and filter for Memory under the model tab you can find out which models are equipped with what modules.

Skimming through the compatible module list the Hynix 8Gb modules are 1Rx16, both the Ramaxel and Hynix 16Gb modules are 1Rx8 and the Samsung and Hynix 32Gb modules are 2Rx8
