Will memory upgrade fix my probems?

I have just swapped a problem Abit AV8 to find I can't get dual channel working on the Neo  2. The corsair  value select worked on the Abit, but not on the Neo. Tried all the tricks, lax timings, upped the voltage etc.
It's a shame you can't test out channel B in isolation becuase I can't decide if the problem is the ram or the cpu, or just a config problem with this motherboard considering it worked on the Abit.
Would changing the memory fix it?
Has anyone found that changing memory never fixed it and they ditched the board?
I feel like I'm having a run of bad luck with changing to  athlon64!

I came to the MSI form an Abit AV8 and transferred the retail cpu/heatsink. It was a ***** to  remove and I bent a few pins. I tried to bend them back inshape before fitting on the Neo2. I have just removed it, with even worse problems. One pin fell off!
But I alos noticed that one pin was bent flat to the cpu surface, as if it a bent pin had not fitted in it's hole and had forced flat by reinsertion. That could explain why channel b failed to function.
My opinion of these new mounts with the rectanguler bases is that they make may make it easier to fit a heastsink square to  the CPU, but they make it impossible to remove the heatsink by gentle rotation around the vertical. They are a "fit once design".

  • IMovie 08 is unusable due to "Hiro video codec is unavailable" will iMovie11 upgrade fix it?

    iMovie 08 is unusable due to a window that pops up telling me ; "Hiro video codec is unavailable" I have to force quit, in order to close iMovie. If I uninstall iMovie 08 and buy iMovie 11 upgrade from the App store will this fix the problem, or will the " Hiro " problem transfer to the latest iMovie version?

    Although it's old, this MacTalk forum topic may help:
    http://www.mactalk.com.au/11/43868-imovie-hiro-codec-unavailable.html
    You will need to read through the whole topic. For more information on Hiro, just google "hiro video codec".
    I don't know whether installing iMovie '11 will fix the problem with Hiro. It's probably best that you get rid of all the Hiro items from your Mac, as recommended in the MacTalk topic.
    Just wish to point out that I have no experience with this, but thought the link I've posted above may be helpful.

  • Will Memory upgrade make difference in performance of Toshiba NB notebook?

    WILL IT MAKE ANY DIFFERENCE TO PERFORMANCE IF I UPGRADE NY NOTEBOOK FROM 1GB TO 2 GB?

    If you have XP and an efficient Virus Scanner (I recommend Avira), 1GB should be fine for light usage (internet, email etc..). 2GB will help if you have many apps open at once.
    If you have Win7, 2GB is highly recommended. I doubt one 4GB Module will work on an Atom CPU, check compatibility first. Remember there is only one RAM Slot in the NB series.

  • MacbookPro will not wake up from sleep after memory upgrade

    I am restarting this topic as I have read thread after thread (many years old) and they all just die off with out any definite solution.
    I have a 13" Mid 2010 Mac book Pro which originally came with 250gb HDD and 4gb memory
    I have recently upgraded to a 256 SSD and a 1TB HDD optidrive replacement along with a 8GB memory upgrade and I am now running Lion 10.7.4
    If I close the lid and open within approximately 1 minute it will wake up quickly as normal, if I leave it asleep for a minute or 2 it will not wake up with out holding the power button for several seconds and then I still need to wait a several seconds for it to respond and actually wake up. Sometimes I will need to completely shut down and restart. If I wanted a computer that takes forever to wake up I would have a PC!
    The last thing I upgraded was the memory so I am sure it is the cause of the sleep problem and not the SSD conversion which was working fine with the original 4GB mem before upgrade.
    I have read about resting the PRAM, resetting PMC as well as executing a line in the terminal, but all of these seem to have variable success. I have tried every thing but using the terminal to adjust the hibernate mode setting as I am not proficient with terminal and don't actually understand what changing this setting does (sudo pmset -a hibernatemode 7).
    Has anyone resolved this sleep problem and what did you do? I would greatly appreciate some knowledgeable insight on the hibernation settings, and what running the line in the terminal is actually doing... even better what is the default so I can change it back if it doesn't resolve the problem.
    A simple memory upgrade causing such a issues is very irritating.... Any help would be greatly appreciated!

    But still, the sleep issue persists, so it is a more subtle timing issue. I upgraded my MBP with a Corsair 8GB kit ( http://www.corsair.com/us/corsair-mac-memory-8gb-ddr3-sodimm-memory-kit-cmsa8gx3 m2a1333c9.html ) and it indicated it had 9-9-9-24 CAS timing. It has worked flawlessly till now. Note that my Mac is a Late 2011, whose memory runs at 1333 MHz.
    As far as I can tell, the 13" Mid 2010 models used 1067 MHz memory with 7-7-7-20 CAS timing: http://www.corsair.com/us/corsair-mac-memory-8gb-dual-channel-ddr3-sodimm-memory -kit-cmsa8gx3m2a106c7.html

    I've encountered 4HDD/11/40000000 SATA(0,0). AFTER SOME RESEARCH IN APPLE COMMUNITY, I LEARNT THAT IT'S A HARDWARE ISSUE. SO I WILL BE TAKING MY MACBOOK PRO TO NEAREST APPLE STORE. MY QUE IS, WILL IT BE FIXED IF I UPGRADE FROM OSX 10.8.5 TO MAVERICKS? What other options do I have? What can be an approximate cost for fixing this problem?

    Of course not. It's a hardware problem, so it can't be fixed by upgrading software. The only option you have got is to take the MacBook to an Apple Store or reseller.
    That error indicates a problem with the hard drive. What you have to do is to make a backup of your files and take the MacBook to an Apple Store or reseller, so they can confirm that the problem is the hard drive and not the SATA connector, which could be worse.
    If it's a hard drive issue, it's not expensive (about $100-200, depending on the hard drive). If it's a SATA connector issue, the whole logic board may have to be replaced.
    Note that you can replace the hard drive yourself if you want, but the cost between doing it yourself and taking the MacBook to an Apple Store or reseller is similar

  • I have an iMac 5,1 with an Intel Core 2 Duo. I'd like to be able to use iCloud, but need Lion which is too big. How much memory can I add? And will this upgrade allow me to install Lion?

    I have an iMac 5,1 with an Intel Core 2 Duo. I'd like to Lion, in order to use iCloud, but the specs indicate I don't have enough memory. How much memory can I add? And will this upgrade allow me to install Lion?

    I believe your model iMac can address 3 GB RAM; the minimum for Lion is 2 GB - however, that is an absolute minimum for very light use. You would be much happier with a minimum of 4 GB.
    http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.16-20-inch-sp ecs.html
    (You can install 4 GB, but it will only be able to address about 3.1 - 3.2 GB)

  • Memory upgrade - computer won't come on

    Hi all,
    Last week I put a new battery in my MacBook and noticed that one of those three screws by the memory slots was loose. I tried to tighten it but it (or perhaps the hole) was apparently stripped as it did not work. I was able to get the battery in by holding it down and the computer worked fine. Then my memory upgrade arrived and after getting the right screwdriver I was able to unscrew everything, put the new memory in, and put that plate back on. . . except that one screw would not go back in. I was again able to get the battery in by holding that plate down, but the computer would not turn on. The power light just kept blinking, even when I used the power cord. Not knowing if my computer failed to recognize the new memory, I put the old memory back in, but the computer is dead. It seems to power on but the screen is dark. I am using my husband's old computer.
    Do you think it's an issue with the memory? I'm fairly sure I put it in correctly, and didn't think that would affect whether or not the machine even came on. My own thought is that without that stupid screw down tight something is not connecting anymore, and that I will have to take it to the Apple Store to get it fixed. Does that sound right and if so - any idea what it will cost? Should I just get a new computer?? I attempted to do my own upgrade to save money (Apple Store told me $180 to install 2MB!!) but it's looking like that has backfired.
    Thanks so much!
    ~Gina

    Thanks for your help. Yes, it is a Core Duo MB. It is dead once again so I'm afraid I can't tell you anything besides the fact that I purchased it in June, 2006 so I think it is a first generation machine.
    Like I said previously, I did get it to boot but it only recognized one of my old 256MB cards, and I don't know which slot. I tried reseating and switching them and pushing them in as much as I could but it's totally not coming on now. This is the product I purchased:
    http://www.ec.kingston.com/ecom/configurator_new/partsinfo.asp?root=us&LinkBack= http://www.kingston.com&ktcpartno=KTA-MB667K2/2G
    I suspect, though, that something else is going on since the old cards don't seem to work anymore. Is it the l-bracket not screwing in all the way? Could a ribbon cable be loose (I saw this on the Kingston FAQ) Does an entire slot need to be repaired? Should I even bother calling Kingston Tech Support? Is there anything else I can do before taking it to the Apple Store?
    Thanks again!

  • Memory upgrade on iMac G3 700, help with system crashes

    I tried to do a memory upgrade on my iMac, so I bought two kingston 256 MB PC133 modules, but none will work, the system starts, but hangs in about two minutes after loading the desktop. I went back to use the older memory module wich is an spectek, but I need the upgrade, any ideas?
    Thanks!
    FedericoMG.
    Ps: Sorry about my english... I'm from Argentina... :-P

    Hi Federicomg
    The iMac 700 G3 should have been supplied with 1 stick of 256mb ram. However which is the correct type i am not sure as the Apple specifications for this model state PC100 whereas my iMac G3 700 graphite was supplied with 256 MB PC133-333 SDRAM
    http://support.apple.com/specs/imac/iMacSummer2001.html
    Apple profiler from my iMac this is the original supplied RAM from Apple:-
    DIMM0/J13: Size: 256 MB
    Type: SDRAM
    Speed: PC133-333
    1) I would re-instal the original ram and open system profiler to see what type the ram is.
    2) Keeping the original stick in place add another stick of the new ram and look again in profiler to see if its recognised and again try the second stick to see if there's a problem with one of the sticks.
    I am currently running my iMac with a small upgrade of RAM and the additional RAM is 128MB of PC100 and i have noticed the performance improvement since adding the PC100 so it's working and i have suffered no ill effects doing this..

  • Memory upgrade fail - Kernel panic after put old memories back

    I People, this is my first post here and unfortunately is to report a problem, not to help friends.
    I did an memory upgrade last weekend. After this, he will not boot normally, only in safe mode.
    I discovered that they sent me 1333Mhz memories, and my mac (mid 2009) supports only 1066Mhz.
    I put the old memories again, however I believe that the system did not recognize.
    As you can see below, the system recognizes two modules:
    Memory Module: BANK 0/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353237334448302D4348392020
    Memory Module: BANK 1/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353637334648302D4346382020
    It is not true, I' using now 2 x 2GB, DDR3, 1067 Mhz (stock)
    I tried to reinstall the system, but when I try, I got crash again.
    how can I solve this issue?

    Hi BGreg,
    I already reset the PRAM as you said.
    I've cleaned the memory modules as indicated by Linc above.
    Today I formatted my harddrive to try a clean install, but system crashs after 5%, 10%.
    There is something making me worried:
    In one of my tries, I opened the system view to check my actual hardware configuration, and to my surprise, the system shows me 8GB installed. Cannot be. I have 2 x 2GB.
    Where my system stores this information? There is a way to reset it? I tried last hour install the snow leopard, that cames with my mac, by DVD, but does not worked too.
    Thank you all so far.
    Giuliano

  • Memory upgrade

    Hi,
    Can I install 2 x Crucial 4GB DDR3 - 1333 SODIMM 1.35V 204 PIN - CT51264BF1339J on a Macbook Pro 13 inch late 2011?
    Currently, I have 4 GB (2 x 2 GB) and I want to upgrade to 8 GB. There is a controversial info regarding this particular memory module, some people say it is not compatible.
    When I look to the specs I find:
    204 PIN form factor = OK
    1,35 V = OK
    DDR3 = OK
    1333 = OK
    SODIMM = OK
    Max 8GB = OK (2 x 4GB)
    Latency= 9 cicles (same that stock modules supplied with the laptop) OK
    The thing is Crucial, sell an identical specs module that costs quite more. They claim it to be compatible with Mac. The also sell this one I mentioned as being not compatible. The funny thing is that specs for both are identical. I only find a difference on the pricing. So I am really confused.
    Do they one to sell me a more expensive one like being specific for Mac or there is a hiden specification that makes the two modules to differ from each other?
    Can somebody confirm this info to me, please?
    Many thanks in advance
    Best Regards

    News on this subject:
    A Crucial support representative replied saying:
    "Mac compatible memory is guaranteed to work in your specific system.  There may be subtle differences in non specific memory that will cause it not to work for you such as chip solution and the configurations of chips..."
    Well, I find it very ambiguous technically speaking. If they sell good quality memory as they claim, I do not see which subtle differences will affect the functionality. The chip configuration is standard and chip solution is about quality. So Crucial should be all right as everyone claims (even if manufactured in China)
    So I went a head and both 2 x CT51264BF1339J for a very reasonable Belgian price and installed it into my system just two minutes ago. I am writing this using the mentioned system.
    I was on Google after 30 seconds of taping the On button. Although it did not changed a lot as this startup timing is more related to the Hybrid 750GB HDD (SSD + Conventional Drive) I upgraded few months ago.
    I upgraded the memory to run Virtual Box and Parallel desktop more easily though it worked quite good with 4GB. I did not upgraded to 16GB because it is not necessary on my usage. Only one virtual machine at once + E-mail + Browser + some PDF opened. Some technical stuff and nothing like Photoshop or similar. Thus the huge money difference would have gone for nothing if I buy the specific Mac modules of 8GB each as "Crucial Memory Upgrade Tool" subjected me.

  • Memory upgrade not working

    I ordered 8GB memory for my imac mid-2011 model.
    I then tried to install and all I'm getting is three beeps telling me there's something wrong with my memory.
    I've tried all configurations but can't get the 2x4gb modules to work.
    I've had to stay with only the original 2x2gb ones it came with.
    Can anyone please help.
    The only difference, besides the size, between the two modules is that on the 4gb ones is says PC3-10600S-9-10-F2 and the 2gb ones say all the same except instead of F2 at the end it's F1.
    Cheers.

    Which would seem to suggest that you may (unusually) have a doubtful memory module.   Less unusually, you would have paid over the top for it.
    Many people on these forums speak well of the following suppliers.

    Hi
    You have several ways to find out what memory module is compatible and supported.
    You can use a diagnostic too like Everest, you will check the user manual or the Toshiba website for details or you will contact the service in your country for supported modules.
    I will try to answer the question: The Satellite A50 should support PC2700 DDR-RAM like these parts:
    PC2700 256MB (PA3311U-1M25)
    PC2700 512MB (PA3312U-1M51)
    PC2700 1024MB (PA3313U-1M1G)
    Now its your choice. You can also google for the offers
    By the way: Visit the Toshiba Options & accessories site. There you will find compatible parts
