4GB Upgrade from Crucial only recognising 2GB

HI - I've just upgraded my 17" 2.4GHz MBP from 2GB to 4GB using the 2x2GB upgrade pack from Crucial. Problem is that my MBP is only recognising 2GB of it. When I open up 'About This Mac' and click 'More Info' the memory section is telling me that I have 2x1GB sticks installed. I've pulled the sticks and swapped them around ad I've checked that they do actually have 2GB printed on each stick.
Is this a MBP problem or have I bought dodgy RAM ? I'm running Leopard 10.5.1.
Thanks.

Yours is the 3rd post I've seen in the last 2 days where a Crucial 2gb sodimm is showing as a single 1gb.
It looks like Crucial have accidentally labelled some 1gb sodimms as 2gb.
Crucial ram is usually excellent quality. I'd get in touch with them and get the ram swapped out, but also point them to this forum so they can look up the other two cases. Seems like a major error on their part.
Best of luck.

2GB RAM Upgrade from Crucial

Crucial is offering 2GB of mem at $97 for my Macbook and I was wondering if anyone out there had any suggestions or comments about their module and whether or not it was worth it.

I have that same stuff - it worked great in my old 2GHz Core Duo and it works great in my new 2.16GHz Core 2 Duo. Great price too

Is it worth the $ to upgrade from 1.5Gb to 2Gb of RAM?

I have a G4 Dual 450 AGP with 1.5Gb of RAM. I am working on a large catalog. I use InDesign and Photshop a lot. Will I even notice the extra 512 Mb enough to justify the purchase? Thanks.

Hi
You could try using the Activity Monitor application located in the Applications\Utilities folder to monitor your existing memory usage whilst you perform your work. The following article explains how to interpret the information shown:
http://docs.info.apple.com/article.html?artnum=107918
As already mentioned a processor upgrade may be more beneficial. IMHO you get the most bang for the buck with a mid range processor upgrade, perhaps a single 1.4 - 1.5GHz 7455 based one, e.g.

Upgraded from 2gb to 4gb of RAM and now my Imac freezes up all the time.

I have a 2009 model Imac and I upgraded from 2gb to 4gb but now after about 20 minutes of the computer being on it will freeze up randomly. It could be 20 mins - 3 hours of use before it freezes up. I did my research and I'm didn't get any RAM my Imac couldn't handle...so I have NO idea what's wrong. Any help would be greatly appreciated!

As old as it is have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

If i want to use Icloud i HAVE to upgrade from OSX 10.6 to OSX 10.7 and it doesn't seem to work on my mac book. I thought i had managed then it said i needed 10.7 to be able to upgrade to 10.7??? Who can help? In app store i can only upgrade to M.LION?

Dear Community members,
the frustration is that Apple decide to go from Mobile me to Icloud, forcing clients to have an upgrade from 10.6 to 10.7, i do this on my iMAc but the agenda and contacts don't get synchronised within Icloud. It only works on iphone and ipad but my IMAC doesn't synchronise although i now have to correct software.
I also needed to upgrade my mac book pro but by that time mountain lion was launched, i can now no longer find in App store how to upgrade 10.6 to 10.7 since Apple wants to promote Mountain lion. I then decided to upgrade my MAcbook pro to Mountain Lion but ididn't go through, process was each time interupted.
So searching the internet i found a link to upgrtade to 10.7 and after 40 min of downloading the system said that i requiered 10.7 in order to be able to install 10.7.
Hello IKafka?
Can someone help me, since this has taken me now days and days and with zero result, i have to manually input my appointements and contacts twice since the system doesn't recognise. and I bet that afterwards i will need to invest more time to un-double all the data...
Günther DAuwen

If you purchased Lion for your iMac, just log into the Mac App Store from your MacBook using the Apple ID under which you purchased Lion and go to the Purchases page. You will be able to download and install Lion there.
searching the internet i found a link to upgrtade to 10.7
The only place you get get Lion is from the Mac App Store. If you found some other site, that was an illegal copy and almost certainly tied to someone else's Apple ID and hence unusable by you. If the link was just to the Mac App Store, see above.
As to the problem with synchronization to iCloud, that's not a 10.6 question, so I'd suggest you take up that specific issue in either the Lion or iCloud forums, providing full details, and someone there can probably help you sort things out.
Regards.

I had an iPod Classic 5th Gen that I upgraded from 30gb to 80gb. The problem I'm having is that it will not more than about 5.4gb worth of songs. The iPod begins to freeze mid sync and the (-69) error message haults the sync.

I had an iPod Classic 5th Gen that I upgraded from 30gb to 80gb. The problem I'm having is that it will not sync more than about 5.4gb worth of songs. The iPod begins to freeze mid sync and the (-69) error message haults the sync process. The hard drive has been upgraded, it has a new logicboard (with 128mb RAM), new housing, battery, hold / headphone jack. Basically the only original parts are the bezel, click wheel, screen, and data ribbons. Have attempted the 3Rs and have also tried to isolate potentially corrupt audio files and remove them, but this did not seem to be the primary cause. The sync failure consistently happens at just under a 1000 songs (5.4gb) and then it starts to error (-69) any song after that. Your advise would be enthusiastically received.

Here is what worked for me:
My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

Is there a point to upgrade from 4GB to 8GB?

Hi
I have a MacBook Pro Intel Core 2 Duo 2.4 GHz with 4GB memory (2010).
I want to upgrade my hard drive from 250(5400rpm) to a 500GB or bigger (7200rpm).
So I'm thinking since I'm already upgrading, should I get more memory?
I find it sluggish at times, but I've been blaming the hard drive for the most part.
But I'm wondering if doubling my memory would make an even bigger impact on the performance?
I will be doing some Final Cut at some point and video converting, so I'm wondering if the extra memory would be worth it?
*Yes I know it's a small machine for Final Cut. But I had a Mac Pro until I quite my job, so buying it I never thought I would need more power :-S
Anyway, let me know what you think. Thanks.

I would recommend getting a solid state drive rather than a faster hard drive, that would make a far greater difference than upgrading from a 5400RPM HDD to one that spins at 7200RPM and either replace your optical drive with a second hard drive or using an external drive for non-essential storeage. I'd also upgrade the RAM because 2x4GB of DDR3-1066 RAM is super cheap right now, I added 8GB of RAM from Crucial to my 2008 MacBook Unibody for around $80.

Fields in read-only mode for BP transaction in upgrade from 4.72 to ECC6.0

Hello,
This is regarding the query for BP transaction in upgrade from 4.72 to ECC 6.0.
While creating BP / Changing BP system is disabling the fields in compnay code & sales area option. There is a SAP not provided 907860; and specified that the proplem is because of the delta customizing.
All the customization settings are as per the note. And the Synchronization Control is also activated. But still the fields are disabled only.
I have checked the field settings also in Cross-Application-Components & Logistic-Genral.
But these are not working for compnay code & sales area data.
please let me know if anyone has faced this type of problem / found any solution on this.
Best Regards,
Shubhada

SAP IMG -> Cross Application Components -> Master Data Synchronization  Synchronization Control -> Synchronization Control -> Activate Synchronization options
This setting allows you to activate synchronization of BP with R/3. Not maintaining the values may result in certain fields being read-only in BP.
Suggested Values:
Source Object: BP | Target Object: CUSTOMER | Active Indicator : X
Source Object: BP | Target Object: VENDOR | Active Indicator : X
Source Object: CUSTOMER | Target Object: BP | Active Indicator : X
Source Object: VENDOR | Target Object: BP | Active Indicator : X
Have you set all of the above settings??

Try rebooting it and connect. Make sure you're connected directly to a USB port using the Apple USB cable.

I've read similar questions and answers, but I am still terrified to upgrade from leopard to snow leopard. The only reason I want to is because I received an iPad which requires an updated system. I have an external hard drive. I have the disks to upgrade

I've read similar questions and have studied the answers, but I am still terrified to upgrade from leopard to snow leopard on my macbook pro. The only reason for doing it is in order to sync my macbook pro with my iPad. I do have an external drive which automatically backs up every hour. BUT.......I am techno-ignorant as well as techno-paranoid. I have the disks to update to snow leopard but knowing doing so may likely change/alter/lose/obliterate my current set-up, it actually makes me feel sick to think of it.
Years ago when updating via Apple Protection Plan tech support, my screen actually went blank, everything gone! The tech told me not to worry, that "we" would be able to restore things, but several hours later I was still looking at a primitive looking screen that wasn't anything like what I had before. His language was too technical, in that there was an assumption I understood things I had zero understanding of. Example: partition my external drive.
Anyway, living hundreds of miles from an Apple service provider, and no Apple techs in my community, I had to wait for a trip to an Apple Store where one of the wonderful guys at the genius bar spent a ton of time getting things back to normal and actually explaining it enough that I had a vague understanding.
So now I am in the predicament again and won't know what to do after installing the new disks and finding a likely mess or absence of documents etc. on my computer. I don't know how to access the external drive, and even if I did I wouldn't know how to move stuff from that to my computer.
Anyone have any suggestions?

I'm in the same boat as you, I've used Mac's since day one and neglected my Windows education and now it has come to haunt me as I have to learn it like a school kid.
Nearly 99% of all businesses and nearly 95% of everyone use Windows, Steve Jobs declared "The desktop wars are over, Microsoft won" a long time ago.
By 2015 tablets are going to be selling to consumers more than traditional computers, your living proof, you got a iPad.
Apple has already discontinued the Xserver, the Xraid, the MacBooks and the 17" Macbook Pro.
Apple has introduced BootCamp in OS X 10.6 and up, this allows a partition and drivers so one can install Windows on a Mac.
https://www.apple.com/support/bootcamp/
Why do you think they named it "BootCamp"
You can't run a older OS X version longterm like you have with 10.5 anymore, Mac's are being targeted for attacks and older OS X versions are dropped for security updates.
In fact your Mac might still be part of the 750,000 Mac strong Flashback botnet or infected.
https://en.wikipedia.org/wiki/Trojan_BackDoor.Flashback
http://arstechnica.com/apple/2012/04/how-to-check-forand-get-rid-ofa-mac-flashba ck-infection/
See here, Apple has no security updates for 10.5 users and soon 10.6 is going to be ignored next.
https://support.apple.com/kb/ht1222
1-1.5 years is the OS X upgrade cycle. Change everytime like it or not.
So I'm thinking about your long term future and how you obviously don't like change, need local assistance like it appears you first claimed.
So buy a new Mac and upgrade your OS X version whenever Apple shows it in AppStore.
When your machine can no longer upgrade to the newest OS X version, then you've got about another 2 more years of security updates before you have to buy a new machine or risk running a insecure one.

I'm of the maturity and experience that I know a Mac isn't always the best solution for everyone and even Apple doesn't provide the proper hardware, support or features for everyone. Why only store locations in high traffic ritzy areas?
Our SteveJobs fan here is under 18 years old with good eyes, he's not older like we are with bad or failing eyesight.
The new Mac's have hard to see glossy screens and the type/UI can't be scaled up easily to accomadate our older eyes, however a Windows 7 machine does allow up to 150% scale of the UI, type etc., and also there are anti-glare screen PC's and just about no more anti-glare screen Mac's.
I wrote this User tip in case you have trouble seeing the screen, at least you can scale the web browsing up
Web browsing for hard of seeing users
Apple might still be selling the anti-glare 15" non-retina on their online store, it's the "high resolution/anti-glare model"
But I can get a 17" 1080i HD anti-glare Windows 7 laptop at Sager for a lot more performance and screen size for the price than a Mac.
https://www.sagernotebook.com/index.php?page=category_browse&selected_cat=2
Screen size is important as the UI and text can be scaled up for easier reading.
Of course you do now have the option of having Windows pre-installed alongside OS X to begin your transition to the dark side.
Just call and they will accomondate, hold the option/alt key at boot time to swtich operating systems.

Windows 7 looks just as good as OS X, the secret is having a good monitor with most PC's come with don't.
Good Luck and I hope I've given you a lot to think about.

Since I have upgraded from 7.1 then the power consumption increased slightly unbelievable. I have new batteries in my iphone 5 and when I had at ios 7 so was consumption that allows the battery envelope in two days and with ios 7.1 so is it only 12 hours

I want to upgrade to Lightroom 5, but I'm concerned about compatibility with my 2008 intel Core 2 Duo iMac with only 4G of Ram. Will I be able to run Lighroom 5 if I upgrade from Snow Leopard to Lion?

I want to upgrade to Lightroom 5, but I'm concerned about compatibility with my 2008 intel Core 2 Duo iMac with only 4G of Ram. Will I be able to run Lightroom 5 okay if I upgrade from Snow Leopard to Lion? What will happen to the applications that aren't 64-bit compatible? Also the Eye-one Display 2 colorimeter to calibrate the monitor will not run on Lion, so that will be an expensive upgrade to an i1DisplayPro. Is the upgrade important enough to offset the expense? I have an Epson R2000 printer. Will there be problems with the drivers if I upgrade to Lion? It would be great to hear from other mac users who are also photographers and who print their own photos.

Before upgrading to Lion be sure to read this link:
https://discussions.apple.com/docs/DOC-6271
Adobe lists these requirements:
http://www.adobe.com/products/photoshop-lightroom/tech-specs.html
Looking at http://www.everymac.com/ even the earliest 2008 iMac was fully 64 bit, even though Boot Camp doesn't support 64 bit Windows on that machine.

Upgrade from Windows 7 pro to windows 8.1 pro I only get keep personal files only or nothing, I want to keep apps too

when trying to upgrade from windows 7 SP1 to 8.1 pro from the DVD while being in windows I only get an option to keep personal files only or keep nothing.
what do I have to do so I can do a upgrade and keep all the programs too ?
thanks!
Brandon Dillon

I think there might be a way that when you install win 8.1 on a system with existing windows it will copy the user profile to a spare partition and then format the C and the then install windows 8
If you do a rebuild on a Win 7 or Win 8 PC from a recovery partition, the software as standard now on the rebuild gives you the options of keeping your Data, even though it will wipe and reinstall everything as per factory settings.
So this is normal and to be expected.
To be honest I wouldn't even do this... I'd backup everything, install Win 8.1 from complete scratch, not keeping any data and then restore data as I needed it. I am apprehensive about it thinking it knows where all my data might be.... especially with how
some programs like to store stuff.
Of course this means everything to install again, but latest versions always good, a clean install

Recently did upgrade from OS 10.6.8 and to Mainstage 2.2.2 and have lost lights on my Gio pedal only in Mainstage - still have them with Logic. Tried holding button and replugging USB cable, but did not fix it.

I presume that you mean that the switches do not light up as appropriate when you select a Patch in MS?
If so, in Layout Mode, select each of the buttons in turn, and check that they are a) Assigned to the correct MIDI CC number etc, and b) that "Send Value to" has the correct Port selected.
