Upgrading ram modules on dv4-2145dx

              Hello I need a little help about upgrading the ram for dv4-2145dx I need to know two things,first I had tried to unscrew the memory plate or cover but so far the cover just doesn't come off and it just does a clicky sound of sorts even though I had unscrew it and hence I can't access or substitute the ram modules.Second which kind of ddr2 memory module can I use with that laptop can it be 667 or 800 or lower.Well that's all my questions anybody who can help me on this issue I will truly preciate it and thanks for your attention have a great day.    

I've used the Kingston brand on all my mac (ibook 700mhz G3,1.25DDR, 1.25 DP DDR & G5 DC. So far no problem. I recently purchased matched pair of 1gig (2 gi)DDR2 533mhz @ micro center, coast me $235.00. I was thinking about getting a seperate module. But I remember reading somewhere that for trouble free, better get the matched modules. 1gig x 2 per package = 2 gig or 512 x 2 = 1gig. I rather use brand for less head ache (so far).

  • Mixing RAM Modules (1gig + 2gig = 3gig)

    Hello,
    I am about to buy a Mac Mini and I am on a tight budget. The one thing I want to do for sure is upgrade the memory, but I'm in a quandary of sorts given my budget. The retailer where I want to buy the Mini from only sells the appropriate RAM for the Mini in 2gig modules. So here's my question: I know it is possible to mix the stock 1gig stick with a 2gig stick to get 3 gig of RAM total, but will it be worth it to me? I realize that the best configuration would be to slap in 2 2gig modules in and just be done with it, but with 3gig, would I be appreciatively shooting myself in the foot and killing the machine's performance, or wouldn't I notice? I need to have the memory installed at purchase because I am physically handicapped and adding the memory myself is out of the question. And after researching how to replace memory on the Mini, I wouldn't have the courage to ask anybody I know to attempt to do it after buying it. Is mixing RAM modules a good idea?
    Thanks in advance.
    Malcolm

    Nope, I am not confused, There does have generation between Mac mini model. Maybe not official, but we all know. Check About This Mac ---> More Info ---> Model Identifier : Macmini2,1 (That means, 2nd generation)
    Macmini 3,x (means 3rd generation I supposed)
    And the 3rd generation doesn't support Dual Channel, referred to Crucial.com

    Dears,
    Hope you all are in best of your health, I would like to know the command to check the number of RAM modules in M4000 or M3000 Sun Sparc Servers. I think it should be via XSCF Console if am correct? I trigger following command *"showhardconf"* got below output.

    With the above output I understand that we have the following:-
    -> *16GB RAM*
    -> We have memory boards **MEMB#0** and **MEMB#1**
    -> We have 4 modules on **MEMB#0** and they are following:-
    MEM#0A -2GB - if we Upggrade to 4GB what will happen to the existing 2GB RAM?
    MEM#1A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
    MEM#2A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
    MEM#3A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
    -> We have 4 modules on **MEMB#1** and they are following:-

    MEM#3A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
    So, I understand that the above server will have 32 GB Ram as our company ordered recently, Correct?
    In the specifications of M4000 i see that for these servers we can upgrade he Ram upto 128 GB.
    Please guide, any help offerred is appreciated.

    A Key document is:
    http://docs.oracle.com/cd/E19855-01/819-2210-14/819-2210-14.pdf
    The m4000 can have 4 memory modules.
    Each memory module can contain up to 8 dimms. (Two groups on same size (A and B) of 4 dimms). Group A dimms may must not be smaller than Group B dimms. (within a memory module).
    The server can contain 4 memory modules of 8 dimms ... 128GB is attained by 32 4GB dimms. ( 8GB dimms used to be purchasable but are now discontinued ).
    Depending on what you purchased to achieve 32GB on your server then following options are available:
    - If you purchased 2 memory modules of 8GB each simply put these in two unused module slots and goto 32GB
    - If you purchased 2 memory modules of 16GB each simply put these in two unused module slots and goto 48GB
    - If you purchased 4 memory modules of 8GB each using 8 x 1GB dimms then move your existing simms into the group A slots of the new memory modules, goto 40GB and sell the spare dimmms on ebay or put them certain DELL's (then watch the thing crash due to a static dimm destruction issue and possilbe issues as it isn't supported.)
    - If you purchased 8 2GB dimms stick them in your existing memory modules
    - If you purchased 16 2GB Dimms ... and don have spare empty memory modules sell spares on ebay.
    .... There may be further options ....
    In general the person you are purchasing from should be giving good advice ... better than mine above.
    ... My cynical opinion is a lot of partners (and perhaps even Oracle itself) supplying the purchase may be on commission and have no interest and little care in minimising your cost .... having seen the performance of some oracle 'partners' in the uk I can see why some customers might want to move away from oracle hardware.
    Please be aware certain games with switching things about could affect your warrantee ... ( its highly embarrassing when a failing disk in a dilbert has the wrong part number or even worse an incorrect backplate affecting the airflow ... ) ... and what you are really paying for is for an engineer to come and sort your server out if there is a hardware issue. So take some of the suggestions above with a pinch of salt.
    Please be aware while have I tried to be accurate above I may have made a mistake. ... .... (in fact knowing me I probably have).
    Edited by: bigdelboy on 26-Jan-2013 03:51 (NB: adding memory to servers is often a difficult balancing act and may not be cost effective .... and may make smaller dimms redundant in an upgrade in order to maintain supportable/workable configurations). A new T4/T5 may be more cost effective}. Buying fully populated at the beginning is also often more cost effective .... though the largest dimms to achieve highest capacity may be cost prohibitive.

  • HP Probook 4540s upgrading RAM

    Hi,
    I would like to upgrade my memory (4GBs are not enough in theese days) for probook 4540s
    Now, I have 1 module with theese specifications:
    CPU-Z:
    DIMM #                1
        SMBus address        0x52
        Memory type        DDR3
        Module format        SO-DIMM
        Manufacturer (ID)    Hyundai Electronics (AD000000000000000000)
        Size            4096 MBytes
        Max bandwidth        PC3-12800 (800 MHz)
        Part number        HMT351S6CFR8C-PB  
        Serial number         (Personal information removed)
        Manufacturing date    Week 38/Year 12
        Number of banks        8
        Nominal Voltage        1.50 Volts
    Question is:
    Can I add newer model to the second slot?
    I want to buy:
    HP SO-DIMM 4GB DDR3 1600 MHz Unbuffered
    Certificated for PC3-12800 (B4U39AA)
    It seems, the new model of ram module should be compatible with my notebook, but will be compatible with my old module, while working on 2x higher frequency?
    Or I have to buy 2 new modules and  replace the old too?
    Or I missed something and it is not compatible in any way?
    Also, I have red at other forums, that upgrading memory up to supported 16GB takes some performance issues. Is it still ture, or is this already fixed?
    Thanks for answer

    Hi ,
    The model supports the following specification of memory.
    Standard
    DDR3 PC3-10600 SDRAM (1333 MHz)
    Two SODIMM slots supporting dual-channel memory.
    2GB and 4GB SODIMMs
    Maximum
    Upgradeable to 8192MB with optional 4096MB SODIMMs in slots 1 and 2.
    Dual-channel
    Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.

  • 648 Max - Identifying but not using both RAM modules

    Hi!
    I'm totally new here, just stumbled across this forum while googling for a solution to my problem, so please excuse my lack of proper terminology if that should occur.
    I have the following system (data obtained from Everest 2.20 and own brain):
    P4 2,80 GHz, no OC, no HT
    2x Crucial PC2700 DDR-DIMM 1024MB 2,5-3-3-7 @ 166 MHz
    MSI 648Max (MS-6585)
    PowerColor Radeon X1950Pro AGP 256MB GDDR3, no OC
    Thermaltake Toughpower 850W Modular
    Hitachi Deskstar T7K250 160GB IDE
    BIOS (this is my weak spot...) Everest says BIOS type AMI, dated 28/1/2003, no info other than that
    WinXP Home SP3 + all updates AFAIK
    In general, the system is originally ready-built Fujitsu-Siemens system from 2002 (i think), but heavily modified by me (RAM upgrade, HDD upgrade, several GPU and PS upgrades).
    My problem is that the computer only occasionally uses both RAMs (i.e. showing 2,00GB RAM in My Computer's properties). More often than not, however, it only shows 1,00GB RAM. AFAIK this problem is pretty recent, and did not occur when the RAM was new and installed by me. I have tried to systematically testing the two different RAM modules separately in each of the three DIMM slots, and the computer booted and ran Windows desktop at idle without problems in all configurations. I therefore dismissed the possibility of both MB and RAM failure, and reinstalled both modules in DIMM 1 & 2, where they have always been located. The computer ran with 2,00GB of RAM for a day, then reverted back to only 1,00GB the next morning. Tried moving the RAM in DIMM 2 to DIMM 3, and the computer ran another day on 2,00GB. However, this morning it was back to 1,00GB again.
    Through all this, Everest 2.20 has always detected both RAMs in the correct slots, but have displayed 1024 and 2048MB memory on the System Summary page. Rebooting the computer without dismantling it and fiddling with the modules does apparently not change the usable amount of RAM back to 2,00GB when stuck at 1,00GB.
    Anybody know what the issue might be (since none of the components seem to be faulty by themselves) and how to solve it? Please keep in mind that my BIOS skills are shoddy at best (but successfully flashed the BIOS once by help of an official guide, no stability issues after the upgrade), so detailed instructions regarding that might be a bit over my head. The same goes for overclocking or manually adjusting any voltages or freqs, which I've never tried.
    Thanks in advance!
    EDIT: Apparently a total power-off reboot (power down, PS power switch off, push and hold power button till lights go out, switch back on, power up) seems to reset the RAM to the correct amount of 2GB. Any clues?

    The voltage to the memory might need to be raised one notch.  That adjustment is done in the bios.
    You can download the motherboard manual from this link.  http://global.msi.com.tw/index.php?func=downloadfile&dno=3576&type=manual
    Section 3 page 27 thru 28 cover the adjustment of the memory voltage.
    This is for a retail motherboard.  I do not know if your motherboard has this in its bios.  It is in a section under Frequency/Voltage Control

  • Why is my early 2006 macbook crashing after upgrading ram?

    I've got a black early 2006 Macbook. I recently upgraded the RAM from 1gb (two 512mb modules) to 2gb (two 1gb modules). I used Crucial brand RAM if that makes a difference.
    Anyway, since I upgraded, rather than being able to keep more windows open without the computer slowing down, my screen is freezing up and while sometimes it give me eventual control again, many times it will just tell me to restart the computer. This happens when watching any sort of video either online or off a HD. I had a bunch of tabs open tonight with no video playing (but one video loading) and I had to restart the computer.
    Can someone help me? Much appreciated.
    I'm running Snow Leopard 10.6.8 BTW

    FIrst thing I would do is running the Apple Hardware Test Intel-based Macs: Using Apple Hardware Test
    Could be you got a faulty RAM module.
    If faulty contact Crucial for replacement.
    Also check if the the modules are seated correctly and/or reseat them.

  • Upgrade RAM for MacBook Pro (Retina, 13-inch, Late 2013)

    Hi
    Is it possible to upgrade the 8GB to 16GB RAM for the above mentioned macbook pro?

    The Retina display models cannot have the ram upgraded post purchase...the ram modules are soldered to the logic board.

  • Can't upgrade RAM on new Macbook Pros?

    I'm preparing to buy a new Macbook Pro, and have been told that the RAM that comes with the book is the RAM you get. No upgrade possible because the RAM modules are soldered into place. Is that so? I've always upgraded our computers to the max. Thanks in advance.

    That is indeed so.
    There still appears to be one model (13" Mid 2012) that is still available that has upgradable RAM.

  • Plz help me with the compaitble ram module

    hey
    i have a problem getting the RIGHT ram module. i got a MacBook Pro 15.4-inch 2.16GHz Core 2
    Duo (MA609LL/A)
    i wanna 2g ram. the one i bought (2GB SODIMM LOW DDR2 PC5300 667MHZ)worked for 40 days and then died. so i dunno what it is id need to buy.
    here's what the vendor had to say in reponse,
    +At first glance , I thought that memory was just bad and regular exchange+
    +would work . But after reading one post online, I contacted manufacturer+
    support.
    +This is unique scenario for you. You do need LOW density memory module for+
    +Apple MacBook Pro 2.16GHz Intel Core 2 Duo (15.4-inch) Laptop, but your System+
    +manufacturer is picky. What they need is not same spec as we have advertised.+
    +Their requirement is slightly different and there is cost difference.+
    +These are two Options for you+
    +Option 1 : Refund
    +Option 2 : Upgrade+
    +Option 2A : Memory upgrade from OEM manufacture. We have purchased from them+
    +and they are reliable. Price difference is low and it is what you need without+
    +spending bunch with major manufacturer. Cost difference is $ 17.50+
    +Option 2B : Memory upgrade from Major manufacturer as specifically recommended+
    +by Manufacturer.. Price difference is high but then you know it is what you+
    +have been asked by manufacturer to have . Cost difference is $ 18.50+
    +Thank you+

    Crucial is 1000x better and more reliable than some random seller on Ebay. I wouldn't buy RAM from Ebay, especially when you can get the same thing for $1.00 more from a much more reputable seller.
    If you have 1GB of RAM now, an upgrade to 2GB will make a big difference. I've enclosed links below to single 2GB chips that will be compatible with your MBP from both Crucial and OWC.
    CRUCIAL
    OWC
    You can decide which you like better, they are both $48.99 I believe.
    same thing to me, except for the brand name, i guess.
    The brand name is relatively important with RAM. Macs are selective about good quality RAM; dodgy RAM from just any random seller on Ebay may not work, as you found out. With either of these resellers, you also get a lifetime warranty. Anyone on these forums will tell you that they will stand firmly behind their product if it ever fails. Ever. You can't get any better than that.
    doesn't apple make one one of these? an apple brand?
    No. Apple uses third-party RAM in all of its machines. Apple does not make its own brand of RAM.

  • Warranty with RAM-modul from third-party manufactor

    Hello,
    does anybody know if there exists an declaration of Toshiba that the use of third-party ram-modules does not affect the warranty for the computer?
    Thanks a lot for your answers!
    Greetings from Germany

    As far as I know such document doesnt exist. Fact is that you can upgrade RAM alone without service and this will not affect valid warranty. Toshiba offered list of compatible and tested RAM modules and if you use them they will be recognized properly and everything will be OK.
    Of course, nobody force you to use these modules. On the free market you can buy what you want. It can just happen that you will buy some cheap, no-name modules and they will not work properly.
    So, buy what do you want. For RAM upgrade check Users manuals where you can find exact step-by-step explanation how to put new modules into RAM slots.
    Bye

  • Mac Mini Upgrade Ram and HDD Drive

    Hey there guys, I am going to buy a new mac mini 2.0 Ghz next month. My question is this that on the apple support site it says that if I upgrade the RAM myself or hard disk and I damage any component of the hardware my warranty is void.
    My question is this that, If I buy a 320GB Western Digital Sata drive put it in and a 4GB(2Gb x 2) 1066mhz DDR 3 Ram Modules, Will that void my apple warranty, I am planning to get an Apple Care plan to make it a total of 3 years warranty. So where Do I stand? meaning that I don't mind if the new hard disk and ram that I buy myself is not covered in the warranty as I will have individual warranties from the respective companies.
    But still does it means that, everything is covered Minus the hard disk and ram that i Individually buy.. everything else would still be covered for the 1 year initial warranty and then 2 year for apple care protection plan. does it mean that?
    Is there anyway I don't spoil my warranty? I really cant afford to buy the memory and hard disk from apple, since its too expensive. I am looking forward to get the Mac Mini base line unit, 2.0 Ghz with 1 gb of ram 120gb hdd.

    As far as I can see anywhere in Apple documentation there are no officially user-serviceable part in the mini (anyone have a link to the contrary?).
    But, in the U.S. at least, warranty law seems to be in consumers' favor these days, and unless you specifically break something with your unauthorized upgrade, Apple still has to honor the warranty.
    The mini manual in fact says:
    "If you open your Mac mini or install items, you risk damaging your equipment,
    and *such damage* isn’t covered by the limited warranty on your Mac mini."
    Your damage isn't covered, not the warranty is voided.
    But, NEVER EVER send any product in with a user upgrade even if upgrades are officially allowed -- because it's really common to just be sent back a swap instead of your machine. With the mini, you'll want to observe that doubly so, just to eliminate the possibility of them complaining about your upgrade. Keep the original parts, and put them back in if you ever need service.
    For this Apple Store situation, the only thing he could legitimately charge you for is a "labor charge" for the act of having to remove your RAM *for testing the other problem*. That should be like $30 not $300, and you should get your custom RAM back in a little baggy. Tricking you into buying Apple RAM to "solve" your other warranty problem, or as a condition of getting warranty service, is probably fraud.
    Nonetheless -- definitely not a good idea to bring in the mini with the custom RAM in the first place...
    Note that there are some gray areas as to damage -- for example if you put in a processor upgrade (in the older minis with processor sockets) and that ran much hotter, Apple could legitimately claim the heat damaged some other part that failed.

  • Upgrade RAM to 8GB

    Hi,
    I have HP Compaq 8710w  GC122EA. Operating system is Windows 7 Ultimate 64-bit.

    Sure you can.
    From the Maintenence & Service guide. Only install guaranteed compatible memory modules from well know memory manufacturers if you want the upgrade happen without surprises.

  • Upgrading RAM to 4 GB

    I bought a MacBook in the end of May and wanted to upgrade its RAM to 4 GB as I use my notebook quite a bit for video editing of footage of family trips and children's activities. Presently it has a pair of 1 GB (2 GB total). Would I be able to do that and would this computer fully avail of the upgrade or it's one of those that only has 3.3 usable RAM thingy?
    TIA for all your kind and informative replies.

    Thank you for the quick response GDF!
    Now it seems that one of the pair of the 2GB RAM modules (x2) I just got in the mail from Corsair is corrupted! So I would need to have it replaced by them.
    Meanwhile, where should I install the one good 2GB memory module alongside one of the factory installed 1 GB memory chips, in the bank/dimm 1 or the bank/dimm 0?
    Thanks once again.

  • 15-F018ca upgrade/ram slots

    I want to upgrade the ram. I've tried to replace the only user accessible ram module under the laptop by a same spec 8gb module (but from Crucial) and it refuse to boot. Tried with a few other DDR3 and DDR3L (4gb and 2gb) but the only one that work and boot the laptop is the original one (samsung 4gb-pc3-12800).
    Two questions: In the user manual and on vendor website they all list as two user accessible ram slot. In the bios/boot/utility tool it mentionned that slot/2 is empty. So where is it ? (have to disassemble the laptop to access it?)
    And what memory is known to be a good compatibility for this serie of laptop ? (if a second slot is available 4gb+4gb configuration will suffice but if not what 8gb module is compatible?)
    This question was solved.

    Hi,
    The manula clearly says on page #1:
    Two SODIMM non-customer-accessible/upgradable memory module slots (Core i3 processors)
    DDR3L-1600-MHz dual channel support (DDR3L-1600 dual channel support)
    One SODIMM non-customer-accessible/upgradable memory module slot (Pentium, Celeron processors)
    DDR3L-1333-MHz dual channel support (DDR3L-1600 downgraded to DDR3L-1333)
    DDR3L-1066-MHz dual channel support (DDR3L-1600 downgraded to DDR3L-1066)
    Supports up to 4 GB max system memory (DDR3L-1600MHz module)
    Supports the following system RAM configurations:
    ● 4096 MB (4096 MB×1 or 2048 MB×2)
    ● 2048 MB (2048 MB×1)
    Your machine uses "2.16GHz Intel Celeron N2840 Processor with Turbo Boost Technology up to 2.58GHz" that means only one slot and already max 4Gb that whay it says non-customer-accessible/upgradable memory
