S12 Ion RAM upgrade?

Is it possible for me to upgrade the RAM in my S12 Ion from 2gigs to 3gigs? There was one on the Lenovo store with 3 gigs but my coupon wouldn't work with it. 
I figured that if it's like my S10, There is RAM built into the motherboard and one RAM slot. I probably need to remove the 1 gig stick from the slot and put in a 2 gig but I would like to make sure before I go for it.

Windows allways benefits from more RAM.
One of the features of Windows RAM management is that it will always try to allocate a running app's data-space in physical RAM, so the more RAM you have, the more running applications you can have without Windows needing to utilise the swapfile.
Not only that, but individual threads within an app are given their own data-spaces as well.
Now, a quick check of Task Manager tells me I've got over 700 threads running. And I'm 'only' running IE, Messenger and StickyNotes - hardly a lot of things to want to have running at once. Add in a Firewall and Virus Scanner and you've got a lot of data-spaces for Windows to juggle.
The more RAM you give it, the more 'hands' Windows gets to keep everything in the air with.
The performance of the CPU, though important, is secondary to all this.

  • Ram upgrade not working on Intel S12

    I attempted to upgrade the ram on my new Intel S12. I purchased a 2 GB Crucial 2GB DDR2 667 from Newegg and upon installing, the S12 will not boot. After powering on, there is not any display. All returns to normal after removing the memory. Does any one have any ideas or other experience upgrading memory on an Intel S12?
    Thanks

    Mellamogo,
    My understanding is that there is 1 GB RAM soldered directly onto the mainboard.  The empty RAM slot is solely for upgrade purposes.  As previously mentioned, I believe the Intel Atom systems cannot be upgraded beyond 2 GB total (meaning only a 1 GB module can be used in that slot), whereas the VIA Nano S12s are now upgradable to a total of 3 GB, thanks to a recent BIOS update.
    I received my S12 with the VIA Nano CPU today... I already updated the BIOS and plan to purchase a 2 GB RAM module in the near future.

  • Upgrade S12 ION CPU - Atom N270 to Atom 330

    Hi Everyone.
    I got S12 ION with HDMI slot.
    I am really considering doing this or either overlock it, I found a pretty descent thred here in the forum about the overlock and I consider try it out, but beside that I was considering replace the Atom N270 with Atom 330
    But as far as I see there are pretty big difference in the Watt power that I dont really fully understand so I want to hear your opinion about it? Does it worthy ? Because otherwise I am satisfy with my S12.
    The reason I am doing this is because I want to watch 720p HD through the HDMI on 1900x1600 , I do bealive that my video will be fine on 1080p with better CPU , do you think I am on the right way ?

  • Performance of S12 ION with WinXP?

    I currently have Win7 on my S12 ION.  I have 3gigs RAM on my S12 ION.  I am seriously considering wiping my HD and putting WinXP on instead.  I know there are people on these messageboards who own a S12 ION and have gone from WinXP to Win7, or from Win7 to WinXP.  I am interested to read your thoughts...
    - How is the performance of the S12 ION with WinXP compared to Win7?
    - How difficult was it to switch from Win7 to WinXP?
    - What do you miss in WinXP that you could do in Win7?
    - How difficult is it to maintain WinXP and get it to work with everything you do?

    Hi and welcome .. as spiritedguy says...
    but i think windows 7 (home premium is on S12 ION.. not the "ugly" starter edition ) .. is a younger fresher system... and forthcoming more accelerated and a better battery consumption driver will show as the power in the near future...
    XP is good on S12 ION but i dont think that you got the most of it .. depending on the driver situation (and adobe newer flashplayer) ...
    in conclusion you must decide on your own what is better or more convinient ...  ...
    The best solution in these times is a multiboot system... get the best of both
    wish all a merry christmas time and a bunch of gifts

    First go to the RIM web site and look to see if they have an uninstaller for the device you had.  Some times a reinstall of the application and then running the uninstaller is required for complete removal.
    If no uninstaller is available, then you will have to use Spotlight to find all items with 'Blackberry' and 'Rim' in the titles.  I would also download EasyFind and use that to locate such files.  Often it will locate items that Spotlight misses.
    Ciao.

  • Fixed - bent connector - S12 ION poor wireless performanc​e - Lenovo support no help

    Hi forum,
    I received my Thanksgiving deal S12 ION last week.  The size and format are perfect, the overall performance just what it needs to be, but the wireless performance is unacceptable.  I work for IBM, and have a T60P work laptop and two Y430 laptops, all of which have perfect full bars of wireless signal throughout my house.  But this S12 ION has only three bars in my office next to the wireless G router, and only one to two bars in the next room.  From any other room in the house I cannot connect. 
    I verified that I have the most recent wireless drivers installed.  The ones it shipped with are the most recent on the Lenovo support site.
    I called Lenovo technical support.  After waiting on hold, I was connected, then dropped after another 30 minute on hold.  The second time I called in, I was told I needed to turn on the wireless using the switch.  I informed the tech that I was already connected and that the issue was poor signal.  He then suggested removing Lenovo readycomm, but that is not installed on this S12.  Finally he told me that this is just a netbook, not a laptop and that if I do not like it I should return it. 
    I am so angry with this poor support I would return it immediately, if it were not for the 15% return fee.
    Does anyone else have wireless issues?  Am I mistaken about this being a nice wireless connectivity tool?
    At the price I paid, $399, I can dump this on eBay, but I am seriously disappointed.
    Solved!

    Hi Forum,
    I opened the wireless card slot after reading in other netbook forums that some have had loose antenna connectors. At first I thought that was what I had as one of the leads, the black one, was not seated. It turns out that the connector on the wireless card was bent open.
    See pics:

    [IMG]http://i241.photobucket.com/albums/ff283/skier757/​Lenovo%20S12%20wireless%20card/PICT0002.jpg[/IMG]
    I bent the ring connector closed, reattached the antenna lead, and now I have great signal. Thought you would be interested in the pics.
    I am going to call Lenovo and ask them to replace the wireless card, as there is no guarantee the connector is not damaged, but it is working fine for now.

  • HP Envy 13 1030nr. Windows 7 64-bit. RAM upgrade help.

    I just purchased a RAM upgrade for my Envy 13 and I was trying to figure out how exactly to access the memory module.  I couldn't find a youtube video for the Envy 13 and reading the maintenance manual provides only partial instructions to access the memory module.  It tells you what you need to do (Disconnect the TouchPad cable 2 from the low insertion force (LIF) connector on the system board) but not how to do it without damaging the computer.  I don't want to permanently sever a cable or anything so I'm looking for help via a link to a video or more detailed instructions on exactly how to safely access the memory module. 
    I was under the impression that this would be a quick replacement, but the more I read the manual, the more I think that this is going to be a little more complicated than opening up the bottom and removing the current RAM chip and replacing it with the one I have.  Any help would be appreciated.  Thanks!

    Here is the Manual:
    Manual
    Memory is indeed on the motherboard and getting there requires nearly complete disassembly. See Page 4-26. Not sure how this qualifies as "easy" and if you have not done this before you should get some help. And yes, keep careful track of those screws. 

  • Creating a Windows 7 installation disk for S12-ION (and similar)...

    In a recent (now dissapeard) thread the subject of creating a backup Windows 7 Installation disk that will work with the Win7 Home Premuim OA key on the sticker on the bottom of S12-IONs.
    Unfortunately that thread got stomped on because it strayed off path.
    So, I've started this thread to discuss the afore mentioned subject and request that we do not discuss anything outside that that we are legally allowed to do (and I suggest it might be sensible to avoid making any kind of comment that could be deemed to be outside the acceptable usage policy for these forums).
    OK, so, does anyone have any further information on this process?
    I know we need to start with a (legally obtained) Win7 install disk.
    This can then be altered to operate as any given (or optionally all) version of Windows 7 install disk.
    However, does the disk that one alters need to be a specific version?
    My guess would be that a Windows 7 Ultimate disk is most likely to work, but I suspect all Windows 7 install disks are essentially identical, bar a configuration that one needs to modify.
    Now, one could also, at this point, 'slip-stream' the disk to contain specific drivers, or required other software, for the target hardware (in my case, an S12-ION).
    Would this be necessary?
    What S12-ION drivers/software need to/can be slipstreamed in this way?
    I'm sure there are other questions too...
    Anyway, I plan to do some research, and will post what I find, but if anyone else knows anything about either of these processes, please feel free to contribute...
    Scott

    'Sweet', as I believe 'the kids' say these days.
    Though, I'm still going to look into slipstreaming stuff into a disk - essentially I want what I wish Lenovo provided - one disk with all the base-level drivers and Lenovo management software pre-installed - so I can manage my HDD my way.
    @omgmog: it's exactly those *ways* (or, rather, those that are legal) that this thread is here to discuss...
    Now, an update on my research: I need to stand corrected on one point - Microsoft haven't made it all that easy...
    But, unless Lenovo come up with, I dunno, maybe an iso I can just download and burn to disk, I'm going to keep going and see if I can figure out what the best, most hassle free, way of achieving our legal right is.

  • Hard Drive and RAM upgrades for latest 15" MBP

    I'm minutes from ordering a new MBP. Only concerns are whether I get hte Apple upgrades or shop around.
    I like this Hard Drive...
    http://www.compu2000.com/index.php?l=product_detail&p=6433
    And this RAM upgrade...
    http://www.a-power.com/product-10937-311-4
    If these are equivalent to the apple options I can save hundreds and get a 320 GB drive, which will make a great portable.
    So, does my plan hold water?

    You're on your own for support when you do your own upgrades like this, but generally speaking, it works fine.
    Note that HDD is less risky than RAM. With RAM you run the risk of unstable behavior that is tougher to diagnose. That said, a quality RAM upgrade and some initial testing with any of many available tools is as good as a factory build.
    HDD upgrades are less risky, and I've upgraded (well, replaced after HDD death) ones in my MBPs many many times. I crunch my hard drives more than normal and have to generally replace them about every year. Some of the MBPs don't make this easy, and prepare to get all sorts of cozy with little 0 and 1 sized Phillips screwdrivers and some T6 as well, but it is doable (just not quite for the truly faint of heart).
    Again, you're on your own for support once you do this, so weigh that in your decision.

  • This is the regular status of the memory of my macbook pro. Do you think I need a RAM upgrade?

    Hi there,
    I'm hoping to seek the expert views of the community here.
    I have a MacBook Pro, Late 2011, 17 inch. Running latest version of Mavericks. Speed seems to have slowed somewhat, perhaps since I upgraded to Mavericks, but not certain about that. Based on my research of the Apple communities, I suspect that I may benefit from a RAM upgrade.
    Attached are a few screen shots to assist:
    Based on what I have researched in the community, the fact that I have used 3.99GB of 4.00GB, and have used 5.63GB of Virtual memory, seems to suggest to me that I have well and truly maxed out my RAM. Also there is a high number of read ins/outs (but it had been a wheile since I last did a restart on the MBP (if that has any effect on these numbers here).
    I have also read that my model of MacBook Pro is upgradeable to 16GB of RAM (2 x 8GB).
    Thoughts and views from the community would be greatly appreciated. Will additional RAM help the speed and performance of my MacBook Pro?
    Many thanks.

    More RAM is always a Prudent move...

  • 24" iMac (Primo 2009) strange RAM upgrade issue

    I have a 24" iMac (Primo 2009) at work. I been granted a RAM upgrade by the IT department and have received 2 indentical 4 GB modules.
    The 24" iMac (Primo 2009) uses 1066 MHz DDR3 modules and supports up to 8 GB RAM in 2 slots. I have purchased RAM from this source http://www.dustin.dk/product/5010642132/corsair-4gb-ddr3-1066mhz-1x4gb-so-dimm-i mac-macbook-macpro/#intcmp=searchProvider_SiteSeeker (Corsair Mac Memory so they SHOULD be fine.)
    Here's the issue:
    I had 2x 2GB modules. I have taken both out.
    I have inserted the new 2x 4GB modules but the machine refuses to boot. It gives off 3 beeps-interval-3 beeps-interval (repeats).
    I took out one of the 4GB modules from slot B. It boots.
    I inserted the one I removed in slot B again so we're back at 8GB. same beeps. No boot.
    I switched the 2 4GB modules from slot A+B around. Now beep-interval-beep-interval (repeats) No boot.
    I inserted one 4 GB in slot 1, and one of the old 2 GB in slot 2. It boots with 6GB RAM.
    I inerted only the one that won't boot when in slot B in slot A, beep-interval-beep-interval (repeats) No boot.
    OK - so logical deduction tells me one of the new 4GB RAM modules is defective. No matter what configuration, booting fails with that specific module inserted, though there are different beeps. I also know tha both slots work since the machine works with 6 GB RAM (2+4).
    So I called Dustin, and since we're a big customer they sent a new moduel for free. But, I have the same isssue with the new module!! What are the chances I have recived 1 working and 2 defective modules? not big right? So my iMac seems fine with the old 2GB modules and one of the new 4 GB modules, but says no to the 2 other 4GB modules.
    YES - I have tried resetting PRAM and SMC to no avail. Any clue?

    Switched the 2 modules around, so there's now a 2GB in slot A and a 4 GB in slot B. Still works fine

    I posted earlier on the subject of win7 and ram upgrades.  I did both and it seemed to go fine.  I did the ram first ... replaced a 667Mhz 1gb with a 800Mhz 2gb.  A couple of days later the computer just shut itself down and restarted.  Since then it has done it another 5 times, seemingly at random.  Yesterday I decided to spend some time looking into it and found the 'event log'.  All the shutdowns are recorded as 'critical'.  A search on the web/here showed other occurences of the fault associated with drivers as much as anything.
    After I did the win update I did update almost every driver with ones from this site.
    Other than the shutdowns the only issues I have which are of very mild concern are the length of time the fingerprint reader takes to be present and that occasionally the cursor is unavailable for about a minute after logging on. When you try and control it it jumps about anywhere but where you want it to go.   I rolled back the alps driver and that seems to have sorted the cursor issue.
    So, details of the shutdown from the event log are as follows.

    There's more (I've shown it all below) but it's not that important.  When I looked into it I found details of the problem on the microsoft knowledge base.  Its described here http://support.microsoft.com/kb/2028504.
    I believe I fit into scenario 3 for cause and resolution.
    So, it seems that win7 and mixed speed ram may be a problem on some computers ... probably only a tiny number, but it looks like the HP3507 is one of them.  I did see somewhere that I could down speed from 667 to 266 which might help with memory compatability but I can't see anywhere on the the insydeH20 bios where to do it.  BIOS is version F18 .... upgraded from F15 as part of the Win7/RAM ugrade.  
    Before I swap back to the 'old' memory I'll see if anybody here can come up with any ideas.  It may be that I have to sell off the expensive 2gb memory (ddr2 800mhz 200 pin) for £39.99 from maplin at a bargain price and get 2gb of 667Mhz from somewhere.
    The full 'detail' regarding the fault is below.
    Bye for now.

    Hi DWeiland and Schwede,
    Thanks for your replies. Yes I did the runtime engine registry change and also mass compiled the LV7.1 folder and my sourcecode. I still see the problem as I have set the LV adapter as Lv 7.1.1 runtime engine. Now I have changed it to LV7.1 development system. With this setting, it is not giving any error. Thus I don’t see any problem now. The older version of the code had the adapter as the runtime engine for some reason, now I have changed the setting to the development system. I hope that it shouldn’t be a problem.
    Thanks again!
    Thank you,
    Sasi
