16GB RAM compatibility with Ubuntu 12.04 on Lenovo Thinkpad T410i
 

Hi,
I am looking to upgrade my RAM from the current 4GB to 16GB on my Lenovo Thinkpad T410i running Ubuntu 12.04 (x86_64). My laptop has 2 memory slots and my plan is to install 2x8GB units. Searches of forums and the Lenovo website say for the most part that this is not possible because the T410i can only upgrade to a max of 8GB. And yet some people say it is possible. I was wondering whether someone has managed to do it, before I go ahead and make a purchase.

I realize this is more of a hardware question than a Linux one, but I just want to know if anyone has managed it, and if so, where did you buy memory from?

Thanks!

Yea ... my car has 4 wheels right now. I'm planning to upgrade it to 16 wheels. This will result in more friction and it will lower my MPG. But I still want to do it because I think more is better.

I would be guided by the manufacturer's specifications.

It's also possible to overclock a computer, but it's not a good idea.

Actually, curmudgeonly and presumptuous Emerson, I'm a computational physicist, so more is definitely better in my case. A simple 'no' would have sufficed. Good luck with your car!

I thought I answered this question some place?? Basically I wouldn't try it.

Get a fully documented system that does support what you want or need.

Doubt his comment was to be mean.

From the Lenovo website, Memory spec for the Thinkpad T401i:

I think there's a clue in there. :)

Play Bonny!

Hope you're not discouraged being here...

On behalf of the forum may I apologize for the very little welcoming tone of one of the replies to your question.

The Internet told me what it told you, that is maybe, depending on a host of unaccounted variables. The question, rhetorical, is, is it realistic to beg or borrow, or buy with the right of return, to try it out?

I think the T401i is probably incapable of addressing greater than 8Gb of memory. The 8Gb DIMMs may physically fit but I don't think they'll work. At best you'll still only be able to access 8Gb total, at worst, I'd think it wouldn't boot as the memory management couldn't handle the extra capacity.

I've still got an old Apple Colour Classic which has 12Mb of memory fitted (Wow!) but you can only access 10Mb. I'm thinking same sort of idea here?

Apologies if my post above was a bit sarky.

Play Bonny!

@Soadyheid: no worries at all! I appreciate the help. Thanks all! I was tilting towards upgrading to 8GB anyway. All you guys more or less settled it for me, and with sufficient force, I might add!

When I customize something. I drill down a bit first. I am no

Or whatever. Just a knuckle dragging linux using Biker who rebuilds and fixes motorcycles.

Before I would decide on what IBM site says. I'd drill down and find the motherboard model number and numbers
and search for what max ram can actually happen for the source.

For the longest time. I read that my Panasonic CF-48 P4 single core laptop could only handle 512MB
SDRAM and that the max was 768MB of ram. After some research. I inserted a 1GIG SDRAM and it accepted
it. So drill down a bit if you are a physicist. I would, but what do I know?

I am just a Neanderthal Linux using Biker.

Good luck with it and Happy Trails, Rok

Edit: P.S. I buy ram from Crucial. They at least guarantee the ram for life.
They are more expensive. They also have a ram finder on their site. For finding
part numbers.

If you had the sticks in your hand, it may not hurt to attempt.

I wouldn't pay for the test with new parts.

I'd be sure to run memory tests for a few days no matter what.

Why should anybody install 16 GB of RAM on a laptop running Linux? It just does not make sense. Server, yes. Laptop, no. BTW, more RAM means more power consumption, not what you want running on batteries.

Let me ask this question: What application are you running that needs 16 GB of RAM !?

Answer: none.

Your laptop with 16 GB will just as fast as with 2 GB.

But methinks my car with 16 wheels will be COOL, isn't that what all this is about?

Emerson: I really don't see the need to explain myself or justify my work habits to anyone, but for your information, it's usually a huge array of computational and imaging tools all open at the same time. I also write massively parallel code using MPI C++, which hogs a lot of memory depending on the size of the mathematical problem.

And, believe it or not, I'm actually arrogant enough to want to test them out on the 4 processors I have, before I submit them to a cluster!

Take a moment to Google up just how memory intensive computational jobs in astrophysics and condensed matter physics can get. Even a large linear optimization problem in Matlab might surprise you with its memory usage.

Answer: <moderated>, preferably in your 16 wheel car.

T410i uses the Intel QM57 chipset. While intel hasnt published a max RAM number for the QM57, I cant find any laptop using that chipset which takes more than 8GB.

Its possible that 2 x 8GB would work as 16GB.....its also possible that it would result in boot failure, or only recognise 1 stick for 8GB, etc..

I agree with jefro, if you have the sticks it might be fun to find out. But I wouldnt go buying sticks in the hope you can get 16GB going.

Because they can? RAM is cheap.

Nope, its not that simple.

Adding sticks will increase power consumption, but not by much with slowish, low voltage mobile sticks, it doesnt add that much even with faster desktop/server memory. Adding sticks of a faster speed rating, and/or a higher voltage requirement will increase power consumption.

Replacing RAM sticks with bigger capacity RAM sticks (which are rated at the same voltage and run at the same speed) may increase power consumption a tiny amount, but that would be offset by better caching, so overall battery life can be better.


Did it work as 512MB or as 1GB? I'd bet that it only 'sees' 512MB, and I'd guess that you installed a dual sided 1GB stick, the system is only reading one side.

You'll lose that bet so don't bet the ranch on that.
