Anything to do after upgraded memory to 4GB?

Do I have to press PR+OptionApple combination while first power on after upgraded to 4GB of memory?
What if I forgot to press those keys? What will happen?

Under Mac OS X you should not need to do anything special after upgrading your memory. If the procedure you are referring to dates back to pre-OS X then it definitely isn't needed anymore. I've never, ever heard of that procedure or any need to do any such procedure after a memory upgrade on a modern Mac.

IMac is running slow again after upgrading Memory to 6 GB 800 MHz DDR2 SDRAM. Mail is especially slow. I have searched the community info, but I am really a novice and most of the solutions appear to be beyond my level of proficiency. Please help!

I am at a loss. even after reading other questions and responses. After upgrading to Mt. Lion, everything on my iMac slowed down. I knew more memory would be needed, so I went from 2G to 6G. That worked for awhile, but now, about 3 weeks later, things are slowing down again. Mail is especially slow, when moving from one message to another, and also just plain typing is delayed in mail. iPhoto has had the spinning wheel issue since change to Mt. Lion, but it eventually stops and the app itself is functional, so this is just annoying as much as anything.
Any easy, simple to follow instructions would be appreciated. Is it better for a novice to take to the Genius Bar or to an approved Mac repair center in my area, rather than attempt some of the solutions I've seen offered here. And, if I do, what's the likelihood the issues will be resolvable?? Clearly, I am not the only one with this issue ...
Thanks for any help you can offer.

There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
Otherwise, take the steps below when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

3D performance problems after upgrading memory

I recently purchased an additional 2GB of memory to try and extend the life of my aging computer. I installed the memory yesterday and Windows seems to recognize it (reporting now 3.3GB) but when I dropped into WoW (pretty much the only game I have) the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages). Basically WoW was being software 3D rendered!!!
I went through the usual reinstall drivers, reboot, etc... and couldn't find a fix. I powered down, pulled out 2 of the memory sticks, booted up, and dropped into WoW - it ran at the full 60FPS and CPU utilization was very low (i.e. back to GPU Hardware 3D rendering). I powered down again, swapped the 2 sticks for the other 2 sticks, booted up, and dropped into WoW - again it ran 100% fine. So I powered down, put all four sticks in, booted back up, and when I dropped into WoW it was running in the software 3D rendering mode (20FPS at best and High CPU/Kernel usage).
I've tried the /PAE option in boot.ini - no joy. I've tried /MAXMEM = to 3300, 3072, 3000, and even 2048 - no joy in any of those cases. Has anyone seen anything like this before? Or have suggestions to fix (other than going to Win7-64)?
All info in signature is up to date.
Thanks in advance for any help!

PAE or Physical Memory Extension will not do anything as Microsoft has castrated this feature to such an extend that it has nothing to do with memory addressing anymore when in comes to Windows XP:
http://en.wikipedia.org/wiki/Physical_Address_Extension#Microsoft_Windows
Quote
Windows XP Service Pack 2 and later, by default, on processors with the no-execute (NX) or execute-disable (XD) feature, runs in PAE mode in order to allow NX. The NX (or XD) bit resides in bit 63 of the page table entry and, without PAE, page table entries only have 32 bits; therefore PAE mode is required if the NX feature is to be exploited. However, desktop versions of Windows (Windows XP, Windows Vista) limit physical address space to 4 GiB for driver compatibility reasons.
The feature is already automatically enabled. But since is original function (Address Extension) does no longer exist when it comes to the desktop versions of Windows XP, it won't really do anything you would ever notice.
About the /MAXMEM Switch: In Windows 32bit operating systems, every process is limited to 2GB of memory. The point of the switch is to allow certain applications (or their run-time process) to occupy a higher amount of system memory than 2GB. However, the culprit here is that only those applications are able to utilize this ability that have been programmed (or compiled) accordingly. A special flag (large memory aware) has to be implemented. Otherwise, these application will be restricted to 2GB even though the /MAXMEM Switch has been set to extend the 2GB limit to 3GB. Most 32bit applications come without the "large memory aware" flag and that is why usually, settings the switch won't change anything.
In any case, it is unlikely that /PAE (even if it would not be castrated) and /MAXMEM would have an impact on your actual issue because I doubt that it has much to do with either memory adressing or the memory limit of an indiviual Windows process.

There are a couple of hardware based explanations to consider here. Let's start with the most obvious one:
1. 975X Memory Controller
The main reason that the system chooses to automatically set the Memory Speed to DDR2-667 even though DDR2-800 modules are installed, is that by design the memory controller of the Intel 975X Chipset does not natively support DDR2-800 modules, but
>>Intel® 975X Express Chipset Datasheet - For the Intel® 82975X Memory Controller Hub (MCH)<< [Page 20]
This means, that from the point of view of the memory controller, operating the memory @DDR2-800 actually means overclocking it (with all potential side effects).
Basically, if your initial problem disappears as soon as you reduce the memory speed to DDR2-667, the design limitation of the memory controller may explain your findings.
2. Different memory modules
If I read your signature correctly, you are actually mixing two different kits/models of RAM (CM2X1024-6400C4DHX and CM2X1024-6400C4). This can work of course, but in practice it not necessarely does under all circumstances.
This list (-> http://ramlist.i4memory.com/ddr2/) indicates that there are at least 14 different module types/revisions of Corsair DDR2-800 / CL4 modules that utilize a wide range of different memory chips (Elpida, ProMos, Micron, Infinion, Powerchip, Qimonda, Samsung, Infinion etc.). Even though the superficial specifications for these chips appear to be pretty similar (DDR2-800 / CL5 / CL4), this does not necessarely mean that the modules will respond to the same operating conditions in the same way. There may be small difference in sub-timings/sub-latencies and/or the general responsiveness of the ICs which may affect the operating behaviour of the memory controller (which by the way also includes the PCI-Express interface which your video card is hooked up to).
And again: If running the system @DDR2-667 solves your issue, the possible explanation is that higher clock speeds may amplify (or trigger) potential performance problems that could have to do with the use of non-identical memory modules.
Furthermore: It is also possible that the memory controller's design limitations and the potential compatibility problems that may be attributed to mixing different modules types may reinforce each other in terms of reduced system performance.
3. The BIOS may have an impact as well
There has been known issue with the use of certain video cards in conjunction with 4GB of system memory on this mainboard:
https://forum-en.msi.com/index.php?topic=107301.0
https://forum-en.msi.com/index.php?topic=105955.0
https://forum-en.msi.com/index.php?topic=99818.msg798951#msg798951
What may have come out as graphics/display corruption in earlier BIOS Releases may come out as reduced system performance when using the latest BIOS Release. Of course, this is hard to prove, but I thought I'd mention it anyway. May I ask what amount of video memory your card has onboard?
Fortunately, there is a BIOS version that you could consider to try in this matter. It is not only the last BIOS Release that could be used in order to avoid the corruption issue, but it is (in my oppionion) the best BIOS Version that was ever released for the 975X Platinum PUE Mainboard: W7246IMS.716 [v7.1b6]. I have been using this mainboard for almost two years and have tested almost every BIOS Release that ever came out and I always went back to v7.1b6 as "ground zero".
It will properly support your E6600 (so you don't have to worry about that) and as far as I remember, there are no known compatibility issues with other components. So maybe, you want to give this a shot.
The bottom line is that in a worst case scenario, the problem you describe could be caused by all of the above things at the same time. You cannot really do anything about the 975X Chipset Specifications and the only way to rule out explanation #2 is to test modules that are actually identical (same model number, revision and memory chips). A test of the 7.1b6 BIOS Release is something you should consider. It may be the only way to test the BIOS Hypothesis.
This post turned out to be longer than I intended, but then again, I am well-rested after a good sleep and the wake-up coffee is kicking in pretty good.

648 Max Hangs during boot after upgrading memory

:confused2:Can someone please help me.
I recently decided to upgrade my memory to 1 gig by adding a further 512mb ddr ram to my system. I already have 512mb pc2700 ram and found that pc3200 ram is cheaper so bought that to add, shouldn't be a problem as the manual says it should work with "333 and up". I used all the tried and tested safety methods for fitting ram so I know there has been no ESD (I have built several machines in the past so it is not a stupid error on my part (I hope))
I fitted the ram in the usual manner and turned on the system to find it would beep once (sounds like normal POST to me it always beeps once, however Ami bios beep codes say it could be dram refresh failure? but 1 beep is also POST ok?) and then hangs. No display no nothing. Fans are all running so power is there but no boot.
I looked on the D-Bracket and it has two red lights down the left side 2 green down the right which indicates it is testing memory. That is as far as it gets.
I had to use rather a lot of force in my attempt to fit the memory and feel I may have either cracked the motherboard, or pushed it so hard that it touched the casing underneath and shorted out (Oh dear, ESD). I have tried stripping out every component except ram,display and hard drive but still nothing. I have also tried putting just the old ram back in as it was before, no joy there either.
Could this be the motherboard is dead or the memory or both?
Any help greatly appreciated
DUCKULA

I finally decided to rip out my Mobo and have a good look around. I fiddled with it a while and then put it back and tried to boot up again. I discovered that if I push out the mobo in the opposite direction to the one I used to try and push the memory in, it will boot. Therefore it has to be a crack in one of the tracks in the mobo itself, although I can't see anything, it could just be a hairline crack, but that would be enough.
The lesson learned is, put your memory in before fitting the Mobo into your case, or at least try and support the underside better, whilst you push
I'm off to the shop for a new one (and a power supply).
Thanks guys for the helpful tips, at least I know what to look for next time

Macbook pro EFI firmware 2.7 after upgrade memory utilization high

Hi,
My machine is locking under specific conditions:
Hardware Overview:
Model Name:
MacBook Pro
Model Identifier:
MacBookPro8,2
Processor Name:
Intel Core i7
Processor Speed:
2.4 GHz
Number of Processors:
1
Total Number of Cores:
4
L2 Cache (per Core):
256 KB
L3 Cache:
6 MB

System Version:
Mac OS X 10.7.3 (11D50b)
Kernel Version:
Darwin 11.3.0

After I have updated the EFI firmware to version 2.7 last week, I noticed that my memory utilization has gotten higher. Has anyone experience that?
Before the upgrade, even when I opened my Fusion VMware, I will still have at least 1-2GB available left but now I only left with 200MB available.
How do I troubleshoot? Regret that I upgraded the firmware.

I have not notice that at all. I also use Fusion with XP, Vista, 7 and Mint and don't see any more RAM being used by OS X or the VMs.

Strange colours on screen after upgrading memory.

Hi all.
I bought a 2nd hand eMac from eBay and have just received a 512MB SDRAM module to upgrade the memory from it's current 384MB to 768MB.
On the first install I removed my 128MB module and installed the 512 module - No Boot. (beeping on startup)
I thought I'd try the 512MB module on its own - No Boot (again beeps).
I then tried just my 256MB module - Booted fine.
I then tried the 512MB module on its own and it did boot but this time the display colours were very off (the apple logo in Tiger was pink for instance)
Last of all I took out all ram and reseated it all - Success finally.
Now my questions are:
Were the beeps a memory error warning (I assumed they were)?
Is the display issue possibly related to poorly seated memory?
I do have big hands and found it difficult getting the ram in the eMac, especially with the sharp(ish) mesh on the underside of the eMac.
I feel this may be related to me seating the memory poorly but that time it booted with the colours all screwed has me worried in case something more is wrong.
I'm currently testing the memory with Remember and all is fine so far (I'm up to the 256 block sequential test so far)
Thanks for reading and apologies for the long post!

Thanks for the suggestion srojtas.
The eMac has been running fine since posting this and completely passed the Remember memory test. I also tested it by filling the memory up by opening many apps and it didn't crash at all there either.
The eMac didn't come with a hardware CD sadly, so I can't test it that way!
I feel now it must have all been due to me not seating the memory correctly.

After upgrading memory Ovolab Phlink no longer working

Mac Mini as server running OS 10.5.8.
I just put in 1 GB of new memory in my server (Mac Mini) so now it has two modules one 256 and one 1GB. Nothing else changed.
Since doing that Ovolab Phlink (is my ‘answering machine’ programme) stopped working. It sees that a call is coming in and recognises the number but does not answer. On manual answering it plays the message to the caller but the phone keeps ringing. It also does no longer send a recording of the call per email.
I am not expecting anybody here to be familiar with Ovolab Phlink but wonder if anybody has a clue as to what could have happened that it was working fine immediately before and not working immediately after (all other programmes seem to be fine). Could it have to do with the internal battery having been disconnected? Or?

Thanks for your post sig
You are posting in the "Mac OS X v10.5 Leopard > Installation and Setup" forums which your post has nothing to do with.
I think it does. as I assume it is a soft error to with installing
You should check with the vendor of the program
done already no luck
You don't state if there are other programs that have difficulty working
I did!
(all other programmes seem to be fine)
or if the machine recognizes the additional ram nor if the ram is appropriate for your Mini.
Both is yes and would be the first thing anybody would check and so did I. also with everything else running fine you know the RAM is working.

Does any one experience having slow performance after upgrading to lion? (I'm using an iMac early 2008 with 4gb memory)

I'm having a problem on my iMac early 2008 (2.4GHz Core 2 Duo 4gb SDRAM) after upgrading to Mac OS X Lion.
The animation such as mission control and full screen and especially, launch pad performs really slow.
Sometimes, mission control doesn't even show the animation.
This is terrible and I want Apple to fix these problems or otherwise this is just making my mac useless.
Does anyone experience having similar problem?

thanks for the reply!
I've checked the activity monitor but nothing was taking up the space expect for Flash Player (Safari Internet plug-in, which takes up 29% of CPU)
here's my screenshot. can you see any problems?
and here's another

After upgrading to Lion, the Finder will increase the virtual memory while using external HD

after upgrading to Lion, the Finder will increase the "virtual memory size" while using external HD. I check it using Activity Monitor and found that "Finder" wll increase the "Virtual Memory Size" and "Private Memory Size". and then after a while. the system told me my HD is full and hanging there.
My External HD is 1TB. and I have installed new version Paragon NTFS for Mac V.9.01. I am not sure it is related or not.
but I attached my external HD. the "Finder" will start to increase the "Virtual Memory Size".
please help out this case and solve this issue.
thank you !!!

The one has nothing to do with the other. Virtual memory size and Private memory size are used by developers to analyze their software. it has nothing to do with anything related to the user.

After upgrading my MacBook Pro memory to 8GB it no longer boots to an operating system.

It is a MacBook Pro, mid June 2009 model and 13".
I've followed the installation videos adequately and the orginal 2 x 2GB have been removed with the new 2 x 4GB successfully slotted in.
It turns on and goes past the first Apple logo and the "ding", then lands on a light grey screen.
A black arrow is active but there is no menu bar, icons or anything showing.
After a while the iTunes screen saver activates and I also noticed an alert from BusySync appear!
Looking for an Apple genius to help me sort this one out!

What I find interesting is this:
A black arrow is active but there is no menu bar, icons or anything showing.
After a while the iTunes screen saver activates and I also noticed an alert from BusySync appear!
That suggesting that the computer is booting up - no other way to see the cursor screen saver. It would be strange to see this occur with bad memory but when returning the original RAM led to the same thing...
I think it would be a good idea (start with whatever RAM you have installed now) to do a safe boot. Restart the computer holding the shift key until the grey Apple screen appears. Among other things this will force the system to perform a disk test and will erase cache files that sometimes cause problems. If the computer boots normally into Safe Mode you can then try booting normally again.

Memory Card blocked after upgrading my nokia E70

Hello all,
Could you help us?
I had upgrading my nokia E70, and after my memory SD card is blocked, I never got a password.
Thanks in advance
Veve

I assume you have updated the firmware?
I don't know the E70 at all but it is likely that after a firmware upgrade then anything on the card will have been removed. Are you able to format the card? Hopefully you will have a back up that you can restore from but don't restore the settings.

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

After upgrading to iOS5 & everything was restored,I couldn't find the downloaded movies I had before.I kept on syncing it with iTunes.I can see videos are taking up space on my Ipad 2 memory in the iTunes page but it doesn't appear,only songs appear on the Music.thank you in advance for your assistance..

They are now in the videos app!

After upgrading to IOS 5, the "other" memory on my phone has taken up 3.7 gb.... is that normal?

My wife has the same phone, but it didnt take up just as much memory after upgrading, any ideas?

See Here > maclife.com/how_remove_other_data_your_iphone
Other is usually around 1 GB...
A ' Large Other ' usually indicates Corrupt Data...
First Try a Restore from Backup...
But... if the Large Other Persists, that is an Indicator of Corrupt Data in the Backup...
Then a Restore as New is the way to go...
