4GB RAM on Acer Aspire One D270 (AOD270)

4GB RAM on Acer Aspire One D270? -> Small Mistake!

I decided to upgrade my netbook from 2GB to 4GB, without reading too much in the internet.
First you have to look at this link:
http://ark.intel.com/products/58916/
- The Intel Atom N2600 processor supports up to 2GB RAM!

When I put the new chip, in the BIOS it was obvious - 4096MB RAM.
But Windows 7 Ultimate 32-bit showed 4GB (2.99GB usable). Pictures:




At first I thought it is due to the 32bit architecture, and I used a kernel patch for Windows 7, like I did before. This time it did not work! Even the whole computer acted a little bit slowly.

However it discovers 3GB, which is way better than 2GB. When you put into account that I changed the HDD with SSD (http://fireswordblog.blogspot.com/2013/01/upgrade-hdd-to-ssd-on-acer-aspire-one.html)
I am even able to run virtual machines on this computer. It is responsive enough.

I still haven't found anybody on the internet making it work with 4GB. I also tried Ubuntu 32 and 64, it also sees only 3GB. So it is not a PAE problem. I also must state, that I have the latest drivers and BIOS 1.09 (which are not so new - shame on Acer!!!!).
So it must be some kind of architecture problem, mostly hardware than software.

Please comment if you have found a solution!

Update (23.11.2013) - I updated BIOS to 1.10 - unfortunately no change :(

Update (02.05.2014) -  Thanks to the Anonymous post below, we discover that the remaining 1GB of memory is probably used for video memory. I started DXDIAG - see the results:








However GPUZ thinks that there are only 8MB:

  1. I own a Lenovo S110 with Intel Atom N2600, 2GB RAM, running Windows 7 Pro 32-bit. I was thinking into upgrading it to 4GB. Will it perform better?

    Performance wise - like opening heavy flash embedded website - how does it improve?

  2. Hi. In my opinion it does not perform better. Flash content needs really good CPU. And don't forget you will have 3GB instead of 4GB!!!!! You can watch your RAM usage if it not close to 90% you don't need it. I run virtual machine on it. The SSD drive however increases the performance.

  3. hi! In my opinion problem is in bios - not able turn on adress relocation. I have some situation...

  4. Windows 32bit will only allow 3GB (2.99 (3GB-video reserved) in your case). It is a mathematical limitation of being 32bits. Only by switching to a 64bit OS will you see all 4GB. N2600 does not have 64bit video drivers though. Intel never created them so that users of the N2600 cannot use more than 3GB on Windows forcing the user to a higher class processor.

  5. Anonymous - it is not quite correct. many people think that because 2^32=4294967296, there is a 3GB limitation in 32bit OSes. However you can use Linux Ubuntu or modify Windows to use the so called PAE mode, where the address is transfered otherwise and much more than 3GB are used. I use Windows 7, 32bit, and all 4GB of RAM are available to me, because I modified the windows kernel (not on this Acer, but on desktop PC). There are a lot of information in the web.

  6. ive got the same laptop acer aod270 with a 4gb ram inside of. the reason why it can only use 3gb of the ram is due to the processor limitations but the last gigabyte a ram is not just wasted but is instead shared with the integrated graphics card make the computer overall a lot faster.

    3. Hi, I'm reviving this thread, hehe. The problem with this NetBook is in its CPU, the Atom N2600 has a limitation of addressable memory; take a look at its specifications in Intel's site: http://ark.intel.com/products/58916/Intel-Atom-Processor-N2600-1M-Cache-1_6-GHz

    4. Hi, will the Acer D270 be able to see 2.99 GB RAM (as mentioned by some ppl here ) if i install 4 GB ? I am fine with even a 1 GB increment.

      Delete
    5. I have three D270's with 4gb and Win7 Home Premium 32-bit . OS sees 2.99 so you get the extra 1gb usable. It is noticeable. Bumps my Windows Experience score from 3.2 to 3.3 also. W7 Starter has a 2gb max lock in OS. Also change the wifi card to Atheros NB037 to get wifi + BT !! Use the drivers from Acer site. Faster and with internal BT. Sweet!

  7. I'm using Acer AOD270 netbook and planning to install Ubuntu 12.04 64-bit. Will it run smoothly?

    1. I tried Ubuntu when I bought my AOD270, but I remember that it did not run smoothly. Besides Ubuntu does not have a driver for the graphic card, and because of that video playback may suffer.

    1. They are all good brands! I think I used kingston, but I cannot check right now, because the netbook was damaged and is in the computer repair service....

    3. All my Acer D270 & Gateway LT40 series (ZE7) run the 4GB DDR3. PC3-8500S, PC3-10600S, and PC3L-12800S all work. Have tried all three types. No issues. Just WAU Starter to Home and above OS to get the 2.99GB usable.

  9. Hi! I've bought kingston 4Gb pc3-10600 for my Aspire one 270d, it sees all of it but only 2Gb is in use, and 768Mb shared for video memory (DSDIXG -> Display).
    Is this because of the windows 7 starter?
    Advise please!

    1. I think that it is because of the Windows 7 Starter ! You can see in wikipedia, that it is only 32bit version, and supports up to 2GB RAM. You can boot a USB flash drive with Linux(i.e.Ubuntu) to make certain that it sees 3GB. So you can install a higher version of Windows7.

    2. Would upgrading to Windows 10 solve the "memory lock" issue?

      Delete
    3. I don't think so. It is more of a hardware limitation in this case. If you have Windows 7 Starter, probably any other windows is better. Few people could run Windows 10 on that netbook, but with mixed results.

    4. Hey i just got a aspire one d270-1186 im new to this small netbook an wonder it say max 2gb ram been reading a bit kinda confused but im running windows 10 an it a bit slow can i put a 4gb Ddr3 in an it work or do i have to change the hard drive to ssd an other stuff

  10. There is some information plain wrong in this thread. I would like to address some of them.
    First, this netbook, D270, does not support 64bit extensions. Tried with Linux LiveUSB. It does not even start. Kernel report that processor doesnt have x64. Period. Windows is in a much worst position, because, even if a netbook might support 64bit, there is no driver for Intel GMA 3600/3650.
    Second, 4GB is not achievable without a serious hack, because I think that is a limitation of a motherboard and the chipset installed. In my experience, this sort of thing that is Intel to blame. Not just for this case. I had motherboard from ASUS, with 945 chipset, with support for 4GB, but in reality, only 3GB is usable. No matter what I tried, computer, even BIOS don't see rest of it. Second example is 960GL chipset for notebooks, which don't even start with 4GB ie 2x2GB, or in best case, start but almost immediately after start, you're greeted with BSOD.
    So, my advice is, DON'T BOTHER. 3GB is plenty enough, and if you have some 50 bucks, euros or dollars, by SSD. There is some pretty sleek Kingston 120GB. This is a move to achieve one little speedy f00cker of netbook. When it dies, well, it will be already time to buy some Ultrabook, or some other perverse innovation.
    Sorry for a lengthy post,
    Cheers....

  11. Excellent help! Thanks Fireswordblogger, and all who posted. Someday, I'll have time to learn to play around with squeezing that last Gb out by tweaking the OS as mentioned, but for now, 3Gb saved my PowerPoint driver system.

  12. I have an Acer Aspire One D270 and it had a 1GB PC3 1333Mhz SODIMM installed so I decided to use a Hynix 4GB PC3 1600Mhz SODIMM and it worked great. In Windows Home Prem. it reserves 1GB of memory for hardware resources and there is 3GB usable. Much better boot time and loads programs much faster. https://twitter.com/EastCoastMods/status/612489204061356032/photo/1

  13. I upgraded to 4GB but still the usable memory shows only 2GB? I thought it shows 3GB as per above post but for me it showing only 2GB usable and even in task manager also 2GB. Please help.

    1. Please check in BIOS first - do you see 4096MB? If YES - then may be you are using windows starter or some other version, which supports up to 2 GB. If you see only 2048MB RAM in BIOS, then you memory board probably is not 4 but 2GB..... check brand/model...

  14. I have an Aspire one d270-1601. I flawlessly installed windows 7 ultimate 64bit and 4gb of ram yet the bios shows 4gb and windows shows 2.99gb of usable ram. Any ideas?

    1. Did you read the blog? It is the maximum amount of RAM you wil get. It is a limitation of the hardware platform, or most likely of the CPU. According to the Atom documentation it supports only up to 2GB. I could not find anybody on the web successfuly using all 4GB. And Acer stopped supplying updates long ago, but perhaps it cannot be fixed by a BIOS or other update..... It is the same with other OS-es not only Windows. As far as I can remember I could not install 64bit OS..... dunno

    2. Thanks but for everyone's information I installed a beta driver for 64bit win7 intel vga...gfx_vista_win7_64 8.15.8.1050. Works perfectly and in device manager it now shows intel graphics media accelerator 3600 instead of standard vga. Here is the best part...under display properties and advanced settings, it shows that 1024mb is being allocated to the graphics memory! So to everyone's question, yes all 4gb is being used! 3 for system memory and 1 for video memory.

      Delete
    3. Just wanted to add that prior to me installing the beta vga driver my windows experience base score was 1.1 due to poor graphics. Now it is 3.3. Big difference now that it has some memory to work with.

      Delete
    4. You are totally right Robert. N2600 is a 64 bit CPU. 32 or 64 bit OS will still be 2.9 Gigs. Rest of 4 Gigs is for hardware reserve. Would recommend 32 bit to get latest 1096 display driver.

  15. It was interesting to read this blog. I was trying to do some research. My laptop came with
    1xr8 pc3 10600 module, so when I searched this on ebay, all options were either 1 or 2gb.
    When I searched part number on RAM is was of course all 1gb on internet.

    So whoever used 4gb, it should have been 2xr8 modules.
    So probably that motherboard having 1xr8 support max input should be 3gb ?

    1. Very interesting, on my laptop the prerequisities check tells me that the built-in GMA3600 is not compatible..... but I can see you succeeded, and there are videos on youtube! To tell the truth, I don't like Windows 8,8.1,10. I like Windows 7 best :)

  17. 4gb will only work with a 64bit operating system. You can install a 32bit but you won't be using all the memory.

    1. It is not quite true. For the 1000th time - I booted 64bit Ubuntu, but again I got only 3GB. On the other hand on my desktop computer I have 32bit Windows 7, with all 4GB accessible, it can work with up to 128GB. It is a kernel hack which unlocks PAE mode. And there are a lot of Windows Server 32bit distributions which work with far more memory :)

  18. What is the best processor can be replace intel atom? I had upgrade my Aspire One D270 to Windows 10.

    ReplyDelete
  19. Nearly all the comments here seem to revolve around the Aspire One D270 being 32 bit, instead of 64 bit. At the risk of asking a stupid question, Is there any possible way of upgrading or swapping out hardware componants (possibly even replacing the entire mother board) to make this machine into a 64 bit computer. Seems to me that if that can be done, then 4, 8, 16, or more GB of RAM would be possible. But as important of a question is, would it then be possible to install a faster processor as well?

    ReplyDelete
  20. I have the same question, and I could not find any info on the internet. Perhaps even if you put a compatible Atom processor, it might not work, and I personally think that the motherboard limits the available RAM to the OS. Not sure. Anyway - if you change everything inside, why bother? perhaps it will be cheaper to buy a new computer. Compatible parts would be hard to find, if any, and probably expensive.... Dunno....

  21. The above 2gb RAM is both OS & CPU. Win7 starter supports max RAM of 2gb. Change to Win7 Home or above max 4gb in OS. Now N2600 supports max 2.44gb = 2.99 in OS. N2800 supports max 4.88gb = full 4gb in OS. It has nothing to do with BIOS version.

  25. Today I installed Win 7 Pro 64 on the Acer Aspire One D270 (AOD270) with 4 GB RAM.
    Original configuration was BIOS ver. 1.03; 1GB Ram, 320 GB HDD.
    Now it has BIOS 1.10 (ZE7), 4GB RAM and 128 GB Intel SSD.
    Windows 7 Pro 64 shows 4,0 GB RAM (2,99 usable).
    I‘m very happy now ..-
    So keep in mind: it is possible!

  26. Question 2GB or 4GB Need to know ASAP Please!!

    SPECS:
    Acer Aspire ONE D270-1824
    10.1" Screen
    CPU/Chipset - Intel Atom N2600 / 1.6 GHz
    Chipset Type Intel NM10 Express
    1 GB RAM DDR3 SDRAM, PC3-8500, 1066 MHz, SO-DIMM 204-pin
    320 GB HDD
    ------
    As far as the upgrade with RAM, I just want to play movies… We know the memory is shared , is it really worth the $25 Upgrade for the RAM, will I notice it when I watch Movies. The unit is a little slow, and I do have to reboot sometimes if the video gets a choppy out of nowhere. This is only used for Downloading and playing movies…and some YouTube… Nothing more. I basically send the Picture over to a 42” TV. With all that send I do want to get into a war with what works and what does not…
    Should I buy a 4GB or a 2GB of RAM ??? I don’t wanna buy something and when I install I have issues. Just want it to work, these are crappy now, but I will spend a few dollars to play my movies, I like it because its small and has decent sixe HDD for my movies that I delete after watching anyway.

    1. Sorry I placed my answer, not exactly under your post...
      Also - don't try H265/HEVC movies, this chip cannot decode them fast enough if you want HD, it only can do H264.

      Delete
  27. No Gags, If you only play movies I don't think it is worth it. For browsing it is OK. More RAM gives you also more cached OS files, so the PC is more responsive, i.e. loads faster the programs. But video won't play smoother with more RAM. You just need to make sure you get the most of your CPU - I noticed only the last versions of VLC player has hardware support for this chip, and also Media Player Classic HD is OK! For youtube you may need a Chrome plugin - h264ify - it forces youtube to give you a compression that the chips renders better. But I am not able to tell is it really the case.....

  28. Firestorm thanks... now only when I play shit thru VLC it crashes the driver...only Vlc tho, strange? Dont care dont really need VLC can use WMP and WMPC hd for 264 it is fine and as for 265 yep it wont play it, anything that is 1080 or higher is a strain too depending on the encode. I have other PCs but like this lil guy for movies and the 500 gig hard drive to download stuff... keeps it all seperate ya know

  29. Hello Every one, I've been playing with this little Netbook for the past 6 months, originally 2GB Win Starter, upgraded RAM to 4 gb (only 2.99) showing, Win 8.1 32bit worked ok, but still had some troubles with HEVC/h265 8 bit, then put in Win7 Home Premium 64 bit, and with Media player classic and a tweek using Strongene Lentoid decoder, HEVC/h265 8 bit works great, 10 bit still has problems. Now Some one previously said that with the N2800 you could actually use the 4GB, and I also found that in a another post, and I can say that it is not rue for me, cause I bought the N2800 card and still no difference in memory allocation, but I do get the 1.86GHz processing power, now does anyone know how to get the full 4GB with the higher chip?

    ReplyDelete
    Replies
    1. Thank you for all that information. It is quite useful, because N2600 (GMA 3600) does not support native H265 decoding. According to this https://ark.intel.com/products/58917/Intel-Atom-Processor-N2800-1M-Cache-1_86-GHz - N2800 supports 4.88 GB RAM. So probably the mainboard does not allow more than 3GB. Probably my guess was right that it is a limitation of the mainboard, not the CPU, as the guy above proposed. Probably it can be fixed by an electronics guru. I guess you can try to boot USB Ubuntu 64bit and see how much RAM is available...

  30. How To How to Update windows 10 using External StorageHow to Update windows 10 using External Storage- In growing technology, there is a lot of ways to enhance our system performance. We can also solve our related issue like updating, upgradation, cpu usage and other a lot of issue. User can also update his windows 10 using USB drive and other related method. In certain cases we fall short of desired space and then we starts to find a sufficient solution to our related issue.So, we can clear the related space for this we need to delete all the unwanted files.
