I have more ram than about my mac shows...

I just updated from 10.4.6 to 10.4.9 after bringing my computer home from the studio to hook it up to the internet. When I updated to 10.4.9, I went to about this mac from the apple menu, and it showed 10.4.9, dual 2.5 powermac g5, and 3.5 gb of ram. But I have 4gb of ram. I have 4 1gb ram modules. Unless, I opened it up and didn't see 4 other ram modules in there.
I'm not sure why the OS update would cause 512mb of ram to disappear. I read another post where someone mentioned the ram not showing correctly in about this mac and having to replace the logic/motherboard. I don't know why that would coincide with an update, unless it was just bad timing.
I also had to move the system and thought maybe a ram module got jostled loose in the ride over. Are there four ram slots in the powermac g5 2.5 or eight? Could there be a loose 512mb module?
Please help.
powermac g5 2.5ghz dual Mac OS X (10.4.9) updated from 10.4.6 and this happened.

See http://support.apple.com/specs/powermac/PowerMacG5.html for details or read the manual that came wtih the machine. If you don't have one, download the appropriate one from http://www.apple.com/support/manuals/powermac/

More ram than specs call for

Specs for my emac specify support for 1GB of ram. In searching for additional ram (I presently have 512MB) I have found some suppliers that claim you can install 2GB (1GB in each of the two slots). I called and they said they have tested this and it works fine. I consider the company I called to be reputable. Has anyone heard of this? What would be the downside of trying it out - other than the extra cost? Is there some kind of power limitations or something that might harm my computer?
Thanks for any insight,
Doug

Ya if you do a search of this group, you will find this has come up a LOT of times and yes your Mac can use more RAM than 1GB if you want.
JIMacG5 I think is being a bit paranoid since, A) your eMac is probably long out of warranty anyway and B) Apple only tests up to whatever RAM was available at the time the model was in production. They do not test RAM for old models so many old models have outdates RAM specs and can use a lot more than they "officially" state they do.

KDE 4.4 eating up more RAM than 4.3

Given the same settings on both versions and after numerous testing, upon bootup, KDE 4.4 is eating up more RAM than KDE 4.3, at least 25 MB more on the average. I realize the developers mentioned they fixed numerous bugs from the previous version, but shouldn't they be working on getting it lighter? Where's the most likely culprit for this additional RAM usage? Can it be attributed to the newer QT version 4.6.1, or something else? Opinions much appreciated, thanks.

As for preload, i installed that some time ago and after 1-2 months i found out that it don't give me a visible speedup on cold start of my apps. In fact, the only thing it was doing was making my linux boot very slow.
Well, it really is that simple. If I have spare RAM, I want something on my computer to start using it.
Preload greatly increases speed on my end on some apps. Mostly big apps, like Openoffice and Kontact, which starts instantly with preload, and takes forever to run if I disable it. It doesn't increase boot time at all for me (I just start it in background, the rest of the loading happens after login and is not noticable on my system). Guess our milage are different.

Don't complain about RAM-use unless you're running out. Free RAM is wasted RAM (and, worse, wasted money you spend on that RAM). If there's RAM not being used, a good OS will find ways to use it.
Instead of worrying about how to free up your used RAM, start worrying about how to use the RAM that is not being used (increase browser-cache, install preload, give Nepomuk more memory, etc).
Certainly free RAM is a wasted resource, but the point of the discussion is whether the increase in RAM usage on KDE 4.4 is a good use of RAM. It is quite possible that the increase in RAM usage is due to bugs introduced in the new code and tracing the exact cause is helpful when one wants to submit a bug report to the KDE team. The RAM saved this way could be used for more useful things in the next release of KDE.
True. I was making a general statement, not being specific to KDE. Memory leaks are obviously not RAM being put to good use.
In KDE 4.3 I found nepomuk all but useless. It slowed down my desktop and had a bad habbit of crashing Dolphin. Now it seems to run pretty well and I barely notice it, but it does take up a lot of my RAM compared to memory-usage in 4.3. But then, I feel like I'm getting something for my money. And I still got lots of RAM to spare, and no ideas on what to use it on.

JVM takes more RAM than defined in -Xmx param on solaris

Hi all,
We have a problem on production installation of our product on Solaris paltfroms: jvm takes more (much more) RAM than defined in -Xmx param and without any OutOfMemory exceptions. (how itt possible at all ?)
The only JNI call in application is SAP interface connector, but application uses a lot of Runtime.exec() calls.
Is it possible to have such kind of "leaks" in java using JNI or Runtime.exec()?
I will be very appreciate for any tip how to find the root of this problem and how we can fix it ?

How do you activate a 10.10.3 download. I have downloaded twice (2 gig each) and have restarted as instructed. I have also rebooted. "About this Mac' still reports 10.10.2 installed and I do not have the new photo app.

I have downloaded 1010.3 twice (2+gig each). The update window shows the 10.10.3 update has been installed, however, 'About this Mac' shows 10.10.2 installed and I don't have the new 'photo' app installed. Once more, the quality of Apple software approaches that of Microsoft - letting the user debug instead of delivering the quality that used to be Apple.
How do I activate the downloaded update.

There may well be a problem with the update package. I initially tried downloading the delta update (not the combo) from the Apple Support web site, and when I opened the package file, the installer ran but terminated almost immediately. I restarted and only got the normal reboot process, not the "Installing software" display. After restarting, I saw some evidence that the firmware updater was cleaning up some files, but nothing else appeared to have happened except that the 1.5Gb package file and a couple small subsidiary files had been left under /Library/Updates/_ManualUpdate.
I tried running the command line softwareupdate tool to see if it would recognize the already-downloaded package file (which is something you might also want to try before downloading again just in case it works), but no such luck. I then relented and used App Store, and that downloaded again and then performed the update successfully.
Of course, then I had to horse around with turning off all the "photos in the cloud" nonsense, but that's another story.

HT1529 Where do i find the serial No on a IMac 4.1 please? I have looked on the "about this Mac" but it does not have the serial No on it!

Until last July, the model identifier on every Intel Mac would tell you exact minimum and maximum expansion in terms of RAM, retail operating system, and any system specific required firmware updates, video and audio expansion capabilities, and patches for Wifi available. The serial number is only of consequence if you wish to date a Mac down to the week. This can help in determining system specific disks, available warranty, and exchange/repair program eligibility. Outside of that the year and month can usually be narrowed down to a six month period with model identifier alone on all except MacPros. So my question is, is it really that relevant for your needs?

I have more songs than I can put on Ipod. How can I un-click all songs in an album without doing each singly, to reduce space? Thanks

I have more songs than I can put on Ipod. Will unclick some songs but one at a time is taking forever. How can I un-click all songs in an album without doing each singly, to reduce space needed on iPod? Thanks

Why not try syncing a smart playlist that updates automatically every time you sync your iPod?
Try something like this:
1. Pull down File > New Smart Playlist;
2. Playlist IS Music; click the plus button;
3. Last Played IS NOT in the last 90 days;
4. Select the option to Limit to xxx items selected by Random and click OK.
Name the playlist that is created something distinctive then sync you iPod with that. It will automatically update based on the last played dates of a tune and you'll always have fresh content on your iPod. Modify the playlist as needed to make it give you the results you want.
Regards,
Michael

IPad says I have more videos than I have

trying to reduce storage I have found that my iPad says I have 44 videos when I only have 9. Where should I look for them please?

First, check the recently deleted folder. If that is empty, try: Why does my iOS device say I have more photos than I can find?

Software updates sometimes do not install. I have two software updates that I continually show up as available to install. When I click on the install button it changes to installed. Checked About this Mac shows that the updates have not installed.

What are the updates?

The App Store tells me I have installed Lion, but About this Mac tells me I'm running 10.6.8

Have tried reaching Apple with no success.
I have been charged for the OS X but don't have it installed. About this Mac tells me I am still running Snow Leopard and when I go into the App Store it says installed and I can't reinstall it. I have reloaded Snow Leopard and then went to the App Store and it still told me I had Lion installed. What is going on? Is Apple ripping its loyal customers off?

The installer should be in your Applications Folder

Adding more RAM to my Pro Mac - config?

Hello folks,
I'm considering buying from OWC (one-third the cost of buying from Apple) - 8GB (2GBx4) PC5300 DDR2 ECC 667MHz 240 Pin FB-DIMMs.
Specifically:
8.0GB OWC Matched Set (2GB x 4) PC5300 DDR2 ECC 667MHz 240 Pin FB-DIMM Modules for all Mac Pro Quad Core and 8 Core systems.
OWC claims these chip sets are Apple qualified memory and they offer their "LifeTime Advance Replacement Warranty" with them. The cooling fins appear identical to the Apple RAM I have already in my Pro Mac.
My config is as follows:
A1 1gb
A2 1gb
A3 >>> proposed 2gb
A4 >>> proposed 2gb
B1 1gb
B2 1gb
B3 empty
B4 empty
Would the above configuration be the correct way to install this new RAM?
Thanks,
mp

Hello Hatter,
I've been so busy on this thing... Update for ya;
OWC RAM arrived the other day; I've had it installed for 2 days now. I did remove my existing (4) 1GB DIMMs before installing the new (4) 2GB DIMMs. Also, I installed smcFanControl.
I've not yet re-installed my original (4) 1GB DIMMs; I think I'll add reinsert them tomorrow...
I ran a TechToolPro test on the 8GB of new DIMMs a few times, and so far everything is perfect. I haven't done any "heavy" dual-core lifting yet. Maybe tomorrow I'll play around in Photoshop and kick the crap outta my new DIMMs.
On the smcFan speeds: Out of the box, the fan speeds are all set at 500rpm. I kicked them all up to 1150rpm - and the temp. dropped from 40°C to 35°C in about 3 minutes. Literally, my MacPro is a cool machine. It's quiet too, I can't hear the fans that much, just an occasional sound - not of rushing wind but the motor - a VERY SLIGHT, SUBTLE harmonic vibration (that description doesn't do its gentle hum justice...) It sounds a little like an old fish tank water pump - very very subtle vibration-like periodical rattle. I'm guessing its a fan's blades slightly out of balance??
Yes, I dusted the heck out of the entire Mac Pro before doing any work on it - so the rattle (again, not a terribly noticeable noice at all) isn't dust. Bearings perhaps?? Anyway -
Question: What are you referring to as the "base" fan? I see four:
1. the CPU Fan
2. PCIe/HDD
3. Rear Fan
4. Power SUpply
Is there a vast difference if - say - the front fans are slower than the rear fans? That is a condition that would ostensibly create negative pressure within the box - and THAT (deductively) would improve airflow, wouldn't it?
Speaking of airflow, I noticed that OWC's DIMMs have not four but about 7-8 fins on each side of the chip sets. I would deduce that more fins equates to greater heat dissipation... But these fins are closer together - which could reduce the air flow between fins. Such dilemmas... :-/ Anyone out there care to comment on more fins meaning more cooling?
Lastly, can the temp. range be too low? Is a temp. range below 40°C a bad thing?
Thanks hatter (and everyone else!),
Cheers,
mp
oh - the other non-RAM issue - it was 10 bad blocks on a 500GB disc. I had a means to back-up the VM guts - and that was enough of a back-up to proceed with a wipe-reload scenario!

Will adding more RAM to my Power Mac G5 make a difference?

I have a Power Mac G5 (Late 2005) with 1 GB of RAM, which is how I ordered it. Sometimes when I am viewing large (large viewing size) video files with Quicktime, the video files get a little choppy from time to time, especially when I have many other applications open. Will adding more RAM fix this or is it not really necessary? Also, does Leopard improve this problem? I am currently using Tiger.

Hey Tim
I'm definitely not an expert - but more Ram makes a huge difference. I'm not sure if more Ram will specifically solve your Quicktime issues or whether upgrading your graphic card is really the answer. Those more knowledgeable should jump in here. Buying Ram from 3rd parties, like OWC (making sure you do have the right compatible Ram), will improve your performance immediately. I noticed the difference when maximizing the RAm on my G4. It cannot hurt. 4GB of Ram for my G5 cost less than $200. I think Ram is the biggest bang for the buck.
Do you really need to get Leopard? The performance of Tiger on the G5 for me is solid. Seems like Tiger is optimized at this point for the G5 processor chips. Why muck around with all the potential problems you read about on these forums. Check out the Adobe forum and hear some of their nightmare stories. Who has this amount of time to waste on fixing what shouldn't need fixing in the first place. Just a thought - hope I'm not out of line for chiming in on this.
Since your model can take 8GB of Ram, indulge yourself and maybe buy another 4GB of matched Ram and if it doesn't solve your Quicktime issues, I'll bet it will make you happy with everything else.

MBP Memory Upgrade Using More RAM than Before

Hey,
I have a 13-inch, late 2011 Macbook Pro with a 2.8 GHz Intel Core i7 Processor. I recently changed my 4GB memory (2 modules) PC3-10600 DDR3 1333 MHz to a Crucial 16GB PC3-10600 DDR3 1333 MHz.
Before the upgrade, the activity monitor would show memory used at around 3.98GB or so, and I was running only chrome with a few tabs open. Using chrome and a few more apps would slow down the computer significantly, though still usable.
After the upgrade, the activity monitor shows memory used at around 6.5GB with the same apps running (just chrome). My computer does run a faster and can handle a lot more apps.
My question is, why is my Macbook using more RAM after the upgrade?
Thanks,
Sebs

The short answer is that memory unused is memory wasted.
Mavericks is designed to decrease reliance upon mass storage, which is orders of magnitude slower than RAM. Mavericks will use all the memory available to it before resorting to using the swapfile. You are likely to find "swap used" to be zero, even with Google Chrome's notoriously profligate use of system resources.

All things being equal, does 4th gen quad core i7 (2.5GHz) need more RAM than 5th gen dual core i5 (2.7GHz) for same tasks?

Bought mid/late 2014 15" MBPr with the i7 2.5GHz and 16GB RAM. I'm within 2 week exchange period at Best Buy, and thinking of switching to 2015 13" MBPr with i5 2.7GHz and 8GB RAM for battery life and weight, and they don't offer the upgraded 16GB RAM option for any 13" models.
Needs to be Best Buy because of gift cards
Use docked at office 75% of time vs 25% out of office, so portability and battery life are nice to have but not as important as if I had 8 hour flights on weekly basis
See appeal of having 5th gen i5 in 13" vs my 4th gen i7 that will be updated this summer
Not a gamer and don't use Final Cut or other video editing, but I tend to leave several applications open and usually have between 1-3 GB free RAM of the 16GB total at any time according to my Memory Cleaner readings
Therefore, worried that 8GB is a non-starter as simple math says that I would have shortfall of 5-7GB RAM based on above readings, but wondering if dual core i5 will use RAM more efficiently than quad core i7
Any help greatly appreciated!

Also to note, would like this to last 4 years, which was reason that I bought the higher spec'd model even though I don't run games or video editing

I have more ram than about my mac shows...
