16 gb so-dimm

Is anyone aware of any 16GB so-dimms in existance? If so, where can I purchase them from

 

You can read a review HERE

 

that link is to 2x8gb dimm's.

so-dimm = laptop size
and the OP is looking for a single so-dimm @16gb.

I personally am not aware of any 16gb so-dimm's available for purchase.

 

Oops! -1 readed him too fast!

Yep! looks only Kit 2x8Go so-dimm by known brands: crucial, corsair, g.skill

 

My only question is why? You can get 16GB in a two-slot configuration, and 32GB in a four-slot configuration. If you want more, get a desktop.

 

People said that when the lightbulb was invented too...


We don't need no stink'n electricity, that's what candles are for.

 

If you need more than 32GB of ram then no laptop CPU is suitable for you.

 

That's a fairly different analogy. I'm really just curious as to what application on a laptop is in need of excess of 32GB. Because if you have to ask if 16GB sodimms exist, you probably don't need them.

 

I doubt any laptop with two so-dimm slots will be adequate to handle any task that requires more than 16GB RAM. And the larger more powerful laptops usually have four so-dimm slots which will allow for 32GB RAM. Beyond that unless you're planning on a super fast RAM drive, there is no use for more than 32GB RAM in a portable form factor.

I believe the HM77 chipset and i7-3920XM CPU's will support max 32GB anyhow, which is the fastest mobile chip you can buy and likely will be in a machine with four RAM slots.

 

Quite possibly the most unhelpful answer I've seen. I don't see why the "why" should matter, but I'll indulge you:

My laptop has only 1 dimm slot exposed through the removeable upgrade panel. I've not completely disassembled the whole chassis, but reportedly the other DIMM module is soldered in, so I'd be wasting my time. My laptop is a VAIO SE. I chose it for the screen. It has 12 GB, but I run scientific experiments on it, and recently my program ran out of memory while executing: I'm not going to enable swap - that would defeat the purpose entirely.

The laptop CPU is more than adequate computation wise, and yes, its memory limit is 16GB. If I could obtain it, I could really make use of that extra 4gb, since my laptop is faster than my university issued desktop.

I come here to ask because my searches yield nothing, and if the item exists it is likely people here will know about it. The patronising "do you actually need that" answers are not appreciated.

 

I believe the i5 sandy bridge will allow for 8GB per channel on the memory controller anyhow, so 16GB chip likely won't be recognized.

 

Well I did answer your question, very well in fact. A laptop with two ram slots can handle up to 16GB, if you need more than 16GB up to 32GB, get a laptop with four ram slots, and if you need more than 32GB, get a desktop. I don't see how that is "Quite possibly the most unhelpful answer I've seen."

And anyway, the "do you actually need XX amount of RAM" question turns out to not be patronizing! Your system told you it ran out of memory, yet you refuse to enable the swap file? Why don't you try enabling the swap file and see if that works. Enable it! Sounds like you have a lot to gain and nothing to risk, no? Because contrary to what you believe, you might not actually need more than 12GB for what you are doing.

 

It's possible to use all that RAM for video editing and photoshop and stuff as project files can consume memory without using the cpu. However you would be working with some serious stuff and if you were in that position to work on stuff like that you would know you need the RAM and you would be doing it on a desktop probably with multiple monitors and other devices to aid your work.

CPU & RAM do not scale together in any way, so saying the laptop cpu would not be fast enough for XX RAM is totally false. CPU processes information RAM stores it. It does not have to be processed while it is stored.

No reason to go for any kind of RAM drive, back in the day it was for uber enthusiast, these days with the invention of a SSD its taking a step backwards.

Infact with SSD even if you consume more RAM than what you have on hand it wont make a big difference as the SSD is pretty much a huge chunk of RAM.

 

An SSD is still much slower than ram. However while there are 16GB dimm sticks I don't seem to find any sodimm sticks for laptops. In general they do not seem available so it is doubtfull current chipsets will support them either............

 

I am looking for 16GB sticks as well. I have done some pretty extensive searching and I don't seem to find any. As for those advising him to get a new laptop or desktop, if he works under a professor, it is not up to HIM to get a new laptop or desktop. The prof will ask for the cheapest option and will be extremely reluctant to spend 1200 odd bucks on a laptop unless he absolutely has to.

 

I as well keep my eyes open for laptops with over 32 GB, but it seems 16's are a ways off and im assuming would be very expensive at first. when I got my 8's for my 8740W about a year ago they were $1300 each on sale

 

This is his personal laptop he is talking about. He says it is more powerful than the computer given to him by his university. But I think the major problem is that his computer tells him it ran out of memory and he doesn't want to enable the page file.

 

Yes and if his personal laptop is not powerful enough to perform a task that is related to his research and his work desktop is slower than his personal laptop (which, in effect, would mean it is obviously not well suited for the task), then he would either need to purchase a new laptop himself with his own money or ask his professor to.

Also, paging is slow. Unless he purchases an SSD in which case, it would speed up, but would still be slower than if the program was on memory. And if he is doing something that requires constant memory access, that speed loss can be significant.

 

If I turn off paging, my laptop runs out of memory too. But if I turn paging on, it never says it runs out of memory, and I notice absolutely no other difference. The pagefile is there for a reason and having it enabled doesn't degrade performance.

 

It does not degrade performance if your paged info is small. Do you do tasks that require constant read and write to memory of large amounts of data? That is where paging is going to affect performance.

Yes the concept of paging is there for a reason - so the OS can store its own stuff which requires a LOT of space on the HDD instead of the memory. IT does not read large amounts of data from this space. As such, there is no reason to occupy a huge amount of fast DDR3 with that info. On the other hand, if OP needs to do large amounts of read and write to memory then keeping it on a slow HDD is useless.

Also, your system running out of memory depends on how much memory you have. If you have 8GB or more of system memory, I find it hard to believe that you are running out of it unless you are running something that is causing a memory leak.

Finally, if you are running out of memory, paging is not going to help. Where do you think the paged data goes to before being accessed by the CPU? MEMORY!! The CPU does not directly read from the HDD. If your RAM is filled, that paged data is going to stay on your HDD until some of your buffer (RAM) cleans up and the data can fit on your RAM. THEN it will be read by the CPU. So if you run out of memory, which the OP is, then paging is not going to help. All it will do is fill up his HDD with information but actually READING that information at a later time will depend on whether his RAM has space to fit that information which, apparently, it does not.

 

They don't make these yet and if they did they'd be thousands of dollars. When 8GB laptop SODIMMS first released they were 3k each as I recall, even now they're still hundreds of dollars.

edit: And I can think of plenty to do with 32GB or 64GB of RAM.

 

ramdisk ftw. I love ram. glad some narrominded people still are happy with 640kb. more for me.

 

maverick1989, saying you don't want to enable the swap because it would decrease performance is ridiculous. If the whatever the OP is doing won't even run in the first place because his system is running out of memory, things can ONLY be better with using the swap file. And especially since you have no idea at all how the program is using memory, you cannot make any statements whatsoever as to the performance with or without the pagefile enabled. You also seem to believe that Windows implements the page file in an extremely unintelligent manner when the truth is that it is pretty good at deciding what needs to go where. No matter what computer you are using or what you are doing with it, if you have the page file disabled and get a warning about not enough memory, the first thing you need to do is enable the pagefile. It just boggles my mind that anyone would refuse to do this.

I only have 8GB of ram because I use a netbook and it only has one RAM slot. I tried without the page file for a while, and windows would notify me every now and then to shut down programs because it was running out of memory. I run lots of stuff simultaneously and I never turn my computer off and carry the power adapter everywhere the computer goes.

 

Again, no one is talking about entirely DISABLING page file. For some reason, you seem to think that we are talking about not using the concept of paging at all. No. What I am saying is that IF OP can get a RAM module that is 16 GB, which he cannot, THEN using the RAM instead of the HDD will be better. You asked WHY anyone would require a 16GB memory module and you were told why. Nevertheless, let me tell you again -

IF OP or anyone can get a 16GB memory module, or ANY sized module that will INCREASE his total available system RAM, said person would rather do that than increase the size of his page file because paging is slower. And yes, things can be better with a page file swap. Things can be MUCH better with a higher RAM. Granted it is not available, but I believe you went on a tangent asking WHY larger RAM is required. THAT's WHY.

Windows 7 requires only 2 GB of system RAM for its 64 bit version. According to your logic, you should have no problem throwing away your extra 6 GB, enabling a HUGE page file section on your HDD and keeping the minimum 2GB RAM. A page file is not to be used in place of system RAM. It is to be used to supplement it. Yes, in this case the OP can do that but his question asking for a 16GB RAM module was not unwarranted at all because if you can get a bigger memory module, you would rather do that than put stuff on your slow HDD.

 

The OP's computer is maxed out and can't do over 12GB. He has the pagefile disabled and refuses to enable it. Did you neither read his posts nor stop to think that maybe that was what I was talking about? Everything I said was specifically about the OP and his situation. And you are rambling on and on about me simply asking what his need was for a 16GB module...

Next time please read the thread, especially the posts made by the OP, don't froth at the mouth so easily and, I beg you, don't make up things that I didn't say.

 

I just bought 16gb (2x8gb) for my laptop for $75 shipped off Amazon to replace a defective 2x4gb. Will I use it all? Who knows, but for $75, who really cares?

Actually, maverick is on the right lines. Your arguments for enabling swap only apply for casual use programs where startup memory is usually useless and no performance hit comes from dumping it into swap. I have a custom program I've written myself, and I am caching 2-3GB of data in memory to avoid incremental disk reads (for performance purposes). The rest of the memory is required for computation on this data. I made a modification recently to address computational speed issues (approx 24h for an experiment), and caused unexpected additional memory use that made the program quit with out of memory error. I've a current workaround (which I don't like) and the program runs in 1h instead of 24h. Allowing data into swap would completely undo the performance gains I've made, and this program would probably take days to run if I did so. I'm not even going to try, because I don't need to waste a few days with my fastest computational machine just in order to say "I told you so".

You did not answer my question. My question was simply "Do 16gb so-dimms exist, and if so, where can I obtain them". Providing alternatives (2x8gb, use a desktop) which I neither asked for nor answered my question is patronising. I didn't ask for your evaluation of my situation, I've done that myself and I am far more confident in my evaluation than yours. Sometimes one simply needs to answer the question rather than pre-empt the users needs. In this case, your pre-emption only served to irritate me. You also then proceeded to engage another user who had more intuition about my situation than you, and be patronising towards him and tell him he was wrong. Nice assumption about my use of Windows, BTW, I'm using Linux. I beg of you, know when to stand down, because you don't always know best.

Also, Hungry Man, I don't quite think your prices are on the ball. I sincerely doubt 8gb sodimms were ever 3k (unless you're talking about registered & buffered), and they are certainly not hundreds now either. My 8GB sodimm cost me just £50. I expect a 16GB so-dimm (if it existed) to be somewhere between £200-300.

 

Maybe this is easier for you to understand, some simple logic based on the scant information given. You have 12GB of RAM and cannot have more. Whatever in the world it is you want to do on your computer cannot run with only 12GB. You have the pagefile disabled. Q.E.D. the pagefile needs to be enabled to run the program. It was true when I said it, and you admit it to being true. That was all I was saying. maverick 1989 was of the belief I was suggesting that RAM is a waste and that paging is better, or at least just as good, and was not on page at all.

Excuse me for being curious as to the application of 16GB sticks. I am truly sorry for insulting your towering intelligence. I am honestly ashamed that when you posed your question I did not immediately recognize your user name as one who was above all others. But please forgive me, because it is not all the time that everyone who posts simple, slightly absurd questions with no further details given already knows everything. Besides the answer to said simple/absurd question, of course.

 

^^ No you cannot find 16GB SODIMMS. The only 16GB sticks that show up...and I have done some pretty extensive search on this.....are 2x8.

 

Hey guess what? They don't exist. And yes, 8 gb SO-DIMMS were indeed stupidly expensive when they were first introduced.

 

You were saying? That, clearly suggests that paging is "just as good" as ram. I wonder what on earth gave maverick that impression.

Yet more condescension; did it not occur to you to stop after my first response stating that I only sought answers to the question? Instead, you turn a patronising attitude towards another forum member, telling him to "please read the thread, especially the posts made by the OP" in spite of the fact that I had said this:

Suggesting that you yourself did not absorb what the OP has said.

Really? Was that even necessary? Even so, my impression here is that you are the one frothing at the mouth, not he. It seems you dislike being incorrect. You couldn't envisage any possibility of the need to disable the pagefile for performance reasons, made sweeping generalisations about paging not decreasing performance, and essentially told another member he was angry when his posts seemed pretty civil (lets ignore the fact that his observations were correct).

 

you are right in most things you say but, they weren't 3k. they were a lot MORE expensive. don't known where you got those absurdly random 200-300 values.

Approx 8700, for upgrading to 32GB memory (lets assume it all comes purely from the memory, and that those upgrades weren't forcing other component upgrades for compatibility, e.g, processor model, mainboard). Thats 8700/4 ~= 2200 per dimm. Thats less than 3k, not more. Also lets neglect the fact thats coming from the laptop manufacturer (and they never charge you more for components than you can buy it yourself).

 

At that time, they were not available elsewhere.


There is a thread on here about them being released...


EDIT:
Starting price was $10kish phone order only...

Let me give you an example. A system with 20GB of RAM and a pagefile enabled will not perform worse than a system with 20GB of RAM and no pagefile. Simply having a pagefile does not incur a performance loss. In your case, having the pagefile disabled incurs a 100% performance loss since the application will not even run.

I only responded to like with like. You the were one to come in here with a brazen attitude. All I tried explaining was that having a pagefile enabled does no harm and that it can even do some good. Yet you and another poster were berating me for it. What I said was not incorrect, but the other poster was arguing against stuff that I did not say. On the other hand, you seem more interested in just belittling me.

Also you keep telling me that I give you a condescending attitude and that I can't admit when I am wrong. But all your posts towards me are purely choleric and you seem to need to endlessly squabble over the original prices of 8GB sodimms after your original guesstimate was false.

 

The OP is like a guy who walks into a bar, picks a fight with the biggest guy in the place, gets beaten up and thrown into the street, then walks back in complaining about the fight that he started.

 

So what did you get from Qind Dao? Money? His old laptop? The argument is between two people. I was part of it and then left because it was clear to me that Qing Daw was not willing to listen to reason. You are doing the exact same thing - walking in and picking a fight. How big of a hypocrite are you? This is about a question the OP asked. It had two answers - give the link to where you can buy a 16GB single SO-DIMM or say no. That was it. There was no reason to go off about "why". It is the OPs god damned problem why. If he has the money and wants to buy it, he will. Is he asking you two for money? No. Is he asking you two for any other favors? No. You have an answer, give it. You don't want to, walk away. Why are you coming in again and again to prove a point? I was not trying to prove a point, I was trying to engage in a debate, which in itself was off on a tangent to the OPs original question, so I stopped and left despite Qing Dao, coming in here day after day and trying to MAKE us believe that he is right. And now you.... lol.

 

This, quite simply. I did also say this

but I suppose that this is obviously starting a fight.

Supposedly my brazen attitude, where I ask a simple question and you don't bother answering but instead to suggest that I don't need what I've asked for. A bit like me asking for directions to a location from a stranger on a street, who replies by telling me I don't need directions ...

 

My prices were accurate. The first time I saw them it was over 3k for a stick. Later on they dropped to 1.2k for both. The last I'd checked they were like 150 each. That's great that they've dropped.

IDK Why anyone cares to tell TC what he can/can't do with his system.

 

I can tell him what he can't do with his system. He can't run more than 12GB in it.

 

Fair enough. My point was that if he wants 16GB of RAM it's fine. Informing him that his system doesn't support it is obviously a good thing lol

 

They are available from this company:

DRAM Memory Modules | 16 Gigabyte DDR3 unbuffered DIMMs | Intelligent Memory

 

Doesn't really matter now that we know that no current Intel platforms support 16GB modules.

 

Interesting thread.

@ the poster above me. I am running 16GB in my Latitude E6520. Assuming I could purchase 2 of the 16GB SODIMMS from the company linked above would my second gen i7 be able to address them? Dell originally stated the max RAM for this system is 8GB, but it clearly is not.

 

Not too long ago i came across a post that memory controler in intel cpus cant work with 16 gb sticks but Amd can. Try searching interwebz for more info about that.

No current high performance intel cpu will take 16Gb dimms. End of story. The max you will ever get are 8gb sticks in all available slots.
