Is Ipad3 memory effectively less than iPad1?

I set up Ipad3 via "restore backup" to load iPad1 data/settings. The unused memory in iPad1 was 14GB (out of 57 available) and new is only 1GB. Photos are taking up 1/3 more space (29gb v. 21GB) and Other is also using much more (6GB v. 2GB). Genius Bar says they think photo size increase is because of new display (larger thumbnails) and Other is because of operating system (even though the operating system already reduces the starting point from 64GB to 57GB). Does this make sense? Is anyone else experiencing this? I will probably be returning it if the iPad3 is really going to eat up that much memory with the new display - not a good tradeoff for me. But I first want to confirm if this is normal or an issue specific to my unit.

Storage, not memory.
In regards to 64GB to 57GB, that is not due to the size of operating system. Per this link, the same applies to flash storage.

Other should not be that large. This means some data transferred was not categorized correctly or there is some partial corruption.

SAP free memory is less than 30MB

HI Gurus,
I have a concerned with regards to the memory of our Server. As per checking from ST06N the free memory is less than 30MB.
Is this normal? Because everytime I reached this low memory Users could not log on resulting to restart the SAP application.
Here is the hardware details:
Server: AIX
CPU: 5GHZ
RAM: 16GB

Why is 8gb only showing total memory of less than 6.5?

why is 8gb only showing total memory of less than 6.5?

Because the difference is due to the operating system taking up most of the diference and the other is how GB is advertised and actually used.

We just recently increased the available memory from 8GB to 24GB to help ensure that there is enough memory. This error never happened on CRM v4. According to the resource monitor, SQL is only reserving 20.7GB of RAM and there is 694MB of RAM in Standby.
The main Async service is using 660MB and the maintenance Async service is using 265MB.
To resolve the issue temporarily, I restarted both Async services this morning. Shortly after everything came back, they were holding fairly steady around 350MB and 200MB. It's been six hours since then.
The last time I spoke with Microsoft about a similar problem, they suggested increasing the amount of RAM.

It became more and more of a problem. It was impacting the users in a more subtle way at first. You couldn't configure the CRM for Outlook client. After a while, they couldn't use CRM in Outlook at all and users reporting not being able to complete phone
call activities. I opened a ticket with MS and they suggested the same as Wilson Lou did. The organization error had nothing to do with the creep on the async services usage of RAM. It was indeed caused by SQL stealing all of the memory. Limiting the max usage
to 24GB RAM has resolved that error.
My Async processes are still using a LOT of RAM, but now that I have more than enough RAM, it doesn't seem to be a problem anymore. They are currently using about 700MB RAM each.
Also, I have upgraded to SP1, UR2.

Why is actual memory less than specifi

Hello
I own a Creative Muvo TX FM (256MB) and I was just wondering why the actual memory is less than 256MB. For instance I see this in other players and in my own I have only 243.5MB.
Also, is changing the format from FAT to FAT32 going to change this "practical amount"?
Thanks in advance for you help/advice!
Jacob

Also, remember that when you are looking at actual space on the player, in the "industry", a mega-byte (MB) is ,000 kilo-bytes (KB) and not ,024.
And yes, the operating system is going to also chew some space.

MacBook Pro and Mac with less than 2GB memory - can they be upgraded to Lion?

Seems an expensive option re buying new memory if not - or am I missing the point?

The full requirements for Lion are
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
It's probable that installer won't run if you have less than 2GB, or if it does that you will have problems with too little memory. However if your Mac has only that little memory it's quite possible that it's old enough not to meet the other specifications, in particular the requirement for Intel Core 2 Duo or the others listed above, and they are absolute requirements.
If your Macs meet the other specs you would find adding memory would make them run better, whether you upgrade or not: it's not terribly expensive.

ITunes 8 Visualizers Both Produce Less Than Spectacular Effects

I have noticed that the ITunes 8 Visualizers running on my MacBook Pro 17" Core Duo with Mac OS X 10.5.4 both produce less than spectacular effects. Has anyone else noticed this problem?
More than half of the 'Classic' Visualizer's effects look like two cones mounted vertically connected at their vertices (as in the letter 'X'). You can scroll through these 'Classic' effects using the 'A' and 'S' keys to scroll backward and forward, and the name of the selected effect will appear in line 2 of the information that appears in the upper-right corner of the screen. These same named effects in ITunes 7.7.1 did NOT look anything like an 'X'.
The new Visualizer's effects look like white globes floating around the screen with various patterns dancing around them to the music. Not very inspiring. You can scroll through the 20 effects of the new Visualizer using the 'M' key.
Something must be wrong ... with the new ITunes software, I presume.

If it were happening to me, I would revert back to iTunes 7.7.1, make sure that the problem does not occur with that version, and then update again to iTunes 8. It is possible that something went wrong with your original iTunes 8 update.
FYI, in order to revert back to iTunes 7.7.1, you first have to trash iTunes in the Applications folder and iTunesX.pkg in the Library/Receipts folder. And any time you install new software, it is also a good idea to run Disk Utility, select your HD, and then click on Repair Disk Permissions.
To install iTunes 7.7.1, you can download iTunes 7.7 at the following link, then double-click on the iTunes.mpkg file that appears, follow the installation instructions, and when installation is complete, drag the iTunes 7.7.1 disk drive icon that remains on your desktop to the trash.

Why can't I open iTunes or apps on ipad1? And why do apple not support the latest update for ipad1 when it's less than 2 years old. I am sick of huge corporations ripping off joe public!

And the processor limitations.

iPad 2: RAM - 512MB, Processor - 1GHz dual-core Apple A5

Similarily, the iPad 2 did not get Siri and some other features in iOS 6.

OracleBulkCopy have memory leak if BatchSize is less than record's count.

OracleBulkCopy::WriteToServer(IDataReader reader) have memory leak if BatchSize property is less than amount of record which were retrieved from IDataReader.
We know workaround for that, but when this problem will be fixed?

You have problem because the batch size property has value *10000* and amount of records(*50000*) bigger than this value.
You can retrieve workaround from my post (OracleBulkCopy have memory leak if BatchSize is less than record's count.

Activity monitor says I have 1 -3% of System Memory free, yet CPU usage shows less than 10% total of all processes

I think you should review what you wrote. There is no question, hence, my reply. I can't tell by the AM listing what applications are using memory. You need to click on the Real Mem column once or twice to display in descending order.
Aside from what you see in AM, what exactly is your problem or perceived problem. You are very low on Free Mem at the moment the screen shot was taken. Those displays are not depicting your computer's instantaneous memory usage.

A detailed look at memory usage in OS X
Memory Usage Performance Guidelines- About the Virtual Memory System
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

I have a iMAC(got it in less than 2 months ago), can I change the memory(upgrade it from 4 GB to 8GB) myself? I mean I need to open the screws and exchange the memory chips. Does it cancel the guarantee?

No, unless you break something or install the wrong RAM, new RAM is not covered by warranty/AppleCare of course.

Purchased ipad2 less than a week ago, can I swap for ipad3 ?

Purchased ipad2 less than a week ago, can I swap for ipad3 ? I had no idea that Apple were going to announce another iPad so soon!!!!

There is nothing wrong with the iPad 2. I'm sticking with mine. Been using Apple products since 1984, but I don't find the need to buy every generation of every category. I don't find the necessary money either....

Why is wired memory less than what's used?

why is wired memory less than what's used?

A whole lot of the stuff you use can safely be paged out and back again with impunity. Wired memory is memory that cannot be paged out to Disk.

My less than 5 month old imac 21.5 desktop is causing me some concern,it is slow to start, problems with bluetooth.problems with wi fi.whe its turned off i notice a graying in the four corners of the screen,this is i think the effects of overheating.

my imac is less than 5 months. old tommorow it goes to murcia for ¿repair?.a 25.1 1mac desktop is a formidable piece of workmanship but thatdoes not stop anything going wrong,as ive found out.in the last month it has begun to heat rapidly thus i think causing a graying in the 4 corners of the screen,this is ugly.as i keep my mac in pertfect grace ie free of dust and prints,also it freezes frequently and downright frustrating.has anyone else had similar problems.on a footnote i beleive apple care will come thru shining,but an answer to my question,wich is why in only 5 months has my imac gone wrong.

Sorry to hear you're having issues with your Mac, but just like pretty much everything else, things can go wrong.
The key is what Apple will do about it now that it has gone wrong. Because you are under warranty, contact AppleCare and explain the issues you are experiencing. There is a chance that your iMac may have to be sent in for repair.
My iMac has had issues since first bought in late 2009, in one form or another and has been repaired three times. AppleCare are going to replace the item sometime in the future, I have no idea when, but I have been without a working Mac for over three weeks now, actually it might be over four weeks.
As you said, AppleCare will sort the problem out for you, let's hope it's not a lengthy repair and they get you up and running quickly.

Is Ipad3 memory effectively less than iPad1?
