Bootcamp on Macbook Not Recognising 4GB RAM?

Am running Windows XP on my Macbook with 4GB RAM, and I don't think that Windows is recognising that there is 4GB available. I wouldn't have thought there should be a setting for this, but I could be wrong? When I check my properties in My Computer, it tells me that I have 2.72 GB of RAM; same when I open up my antivirus software.

Hi to you both and a warm welcome to Discussions,
sounds like you are both using the 32-bit editions of XP/Vista.
While theretically the 32bit Windows can use the full 4GB RAM, in practise only about 3GB are indeed useable. The rest is taken by Windows itself and the hardware reserves some adress ranges of the RAM as well.
Not to forget the 256MB RAM that are used by the 9400 graphics chip (called shared memory).
ETX: Don't get fooled by Microsoft and the Vista SP1. You can still only use the RAm amount Vista reported before applying the SP1.
Microsoft has simply changed what Vista reports from 'useable RAM' to 'Installed RAM'.
Just a marketing trick.
Hope it helps

Is XCode fast enough on a MacBook Air 11" 4GB RAM

Hello, in December I will be buying a brand new MacBook Air for school and personal use. I will also be developing Apps as a developer for iOS using XCODE. My concern is if a MacBook Air with 64/128 GB Flash Storage and 4GB RAM. Should I switch to a pro, I am on a tight limit, but don't want to waste my money and regret it. Also, I heard the MacBook Air is very slow installing programs and such, all I would be able to do is check email.... is that true?
THANKS FOR THE ANSWERS

I am by no means a programmer however I have installed and played around with Xcode on my 11" i5 128gb with 4gb of memory and it seems to run flawlessly. Installed fast considering the immense size of the program (~7gb installed) and ran fine. The screen resolution seems like it'd be the limiting factor on the 11" when running xcode.
Other then xcode, the new MBA's are very snappy even with the base 1.6ghz i5 processor and remember there is an option for the 1.8ghz i7.
I am not recommending against a pro but the air will surprise you. Go in to a local apple store and check them out!
Hope this helps.

15" Macbook Pro i7 4GB Ram good for gaming?

Hi, I'd like to know if the 15" MBP i7 4GB Ram good for gaming? I'm not gonna be an intense gamer I would just like to play games during my down time. All I will be playing is like 1 MMORPG and maybe 1 or 2 FPS games. I will not be doing this all at once. I will be using bootcamp. I have some friends tell me that they wouldn't play games on the MBP because it could ruin it? Is this true? They tell me that it's not wise to play games on this laptop.

It would depend on the games and how demanding they are, but generally laptops make for horrible gaming platforms in general. Apple laptops in particular tend to be among the thinnest of the bunch. A MBP can be thinner than plenty of netbooks out there while packing considerably more punch. That doesn't leave a lot of room for any excess heat that may be generated while gaming.
If we're talking older games, that probably aren't all that demanding, then maybe. If we're talking newer games that are pushing the limits of the laptop's specs, I'd recommend against it.

Will the macbook pro 13" 4GB ram be enough to run LPX ?

Hi there,
As you probably now know, Logic Pro X is finally out and it's time for me to update my old LP9 to this new soft.
I'm going to buy a new mac and here is my problem : LPX needs at least 4GB RAM to run, I was wondering if my 2011 IMAC 21.5" would run it and in particular the macbook pro 13" (no retina screen) would too - cause I need a laptop and don't wanna leave my Imac.
I'm not such a sound ingenieer but I don't wanna spend more than $1400 if I can't run LPX.
Please give me advices
Thanks
Mike

If it runs LP9 ok, and you have a core2duo processsor upwards (or in otherwords a 64 bit processor) that can run mountain lion, then yes, will run as well as LP9 in my experience on older machines.

Disabled iPhone 5 (iOS7) / Not able to restore / Macbook not recognising it

Hi there,
I'm new to this website so please bear with me! This is my problem:
One night my hilarious friends were messing around with my iPhone 5, specifically the passcode. To cut a long story short, my iPhone was disabled.
I've spent the last two days trying to restore it.
Firstly, I followed instructions online to enter into Recovery mode. This seemed to work as there appeared an iTunes logo and a white cable image with an arrow above it onscreen. However, my macbook did not recognise the phone whatsoever - completely ignored it, on iTunes or Finder.
After trying multiple combinations based on several different forums of home button+sleep switch holding/letting go/putting in cable for an hour or two, I took it into my local iStore. The guy in there had it for 3 hours but said he couldn't do anything with it, and he suggested I send it off to Apple. His collegue then suggested I try plugging it into a non-mac computer, e.g. a Windows system.
When I got back I plugged it into my grandma's latptop running Vista. I updated iTunes and plugged in the phone. This time iTunes recognized the iPhone. It said "iTunes has detected an iPhone in recovery mode" and gave me the option to "Restore".
(this is good point to point out I backed up my iPhone a few weeks ago, so don't really care if everything is completely wiped... a new system is quite refreshing anyway.)
I clicked "restore" and it began... took 10 mins, then gave me an error message. I went online and realised I needed to download some up-to-date firmware (which I did).
I clicked "restore" + Shift and selected a firmware file... didn't work. Did it again with a different firmware file... didn't work. I looked into the kind of files I needed, whether I should sign out of my iTunes account while it was restoring..... nothing worked.
To cut a long story short, I feel like I'm at the end of my tether. I've tried a lot of things and this is where I'm at, simply put:
Macbook won't recognise the iPhone, but Windows does.
Windows has problems in the last 30 seconds restoring the phone.
The iPhone is stuck between the apple logo and the iTunes/cable screen, not even going back to the "iPhone has been disabled" home screen.
Throughout all of my tests, my software has all been up-to-date. It's the first thing I check.
Basically I'm between a rock and a hard place: I can't use my iPhone, but I can't restore it either.
I've already talked with my service provider and (see above) taken the phone into the iStore, neither of which could help.
Is there anyone out there who has experienced this and / or able to help?
Thanks,
George

When you say iStore, does that mean an Apple retail store?

Macbook not recognising ipod

I have a Macbook operating OS X and Windows Vista via Boot Camp.
When I connect my ipod via USB the OS X does not recognise the connection in either Finder or iTunes. However, when I am in Vista I can see the ipod as an external drive in Windows Explorer.
This is a problem as I have all my iTunes songs and podcasts in OS X and want to sync my ipod! I do not have iTunes loaded in Vista and only use my ipod in Windows as a hard drive to transfer files.
Can anyone give me some suggestions on what to try to solve the problem?

Try manually reinstalling the latest version of iTunes.

Windows xp not recognizing 4GB ram

I am upgrading a computer from 2GB to 4GB ram. The BIOS recognizes the memory as 4GB dual channel interleaved, but when I get into windows it only shows 2GB.
The OS is Windows XP SP3
there is no onboard video controller
dxdiag tells me video card is an nvidia 7800 GTX with 256MB of ram.
I read about the video card address space issue but it doesn't account for the difference. It should still be at 3.5 or 3.75 GB available to the system.
I have tried enabling the /PAE and the /3GB flags in the boot.ini file one at a time and together.
I have also tried manually setting virtual memory to a different size as well as disabling it.
Any ideas?

Macbook not recognising receiver

Hi folks,
I'm using a MiniDisplay to HDMI cable, to try to connect my MBP to my Denon Home Theatre Receiver.
I'm connecting the cable to the Thunderbolt connection on the MBP, and Blu-ray input on the HT receiver.
The Mac is not recognising the receiver as a display, nor an audio output.
When I use the same cord to connect the MBP to HDMI input on my plasma TV, it works fine. So that eliminates the cord as being the problem.
Any ideas?

I'm having the same problem. LaCie has been no help saying that they will give me a discount if I want to buy a new one.
The drive just doesn't appear in the Finder and the drive doesn't spin up like usual.

After Effects not recognising all RAM

I have just installed After Effects on a new PC with 6GB of RAM, however on the splash screen that appears when loading up AE it says x% of 4GB RAM being used.
Do I need to do something to make it see 6GB?
Thanks in advance.

> I have read all the posts and advice and still come out confused - I
have 8GB (on OS X) and just leave the multiprocessor options switched
off until someone comes up with a clear and concise walkthrough for
idiots like me !
from the post that I linked to:
"Let's take an example of a computer with eight processor cores and 8GB of RAM:
For HD, you want at least 2GB for each process; preferably more. And you almost always want to leave at least 2GB for other applications. That leads to some relatively simple math. For an eight-core system with 8GB of RAM, leaving 2GB for other applications gets you down to 6GB. That's enough RAM for three processes at 2GB each."
Is there something about that that you don't understand? Set Minimum Allocation Per CPU to 2GB. Set RAM To Leave For Other Applications to 2GB. You're done. After Effects will use three processes for rendering.

Battery not recognised after ram upgrade - Help!

I just attempted a Ram memory upgrade that worked fine, but my battery stopped being recognised.
The battery was fine before, even so - I bought a new one (I tested in a different computer - it worked there) - still doesn`t work.
I decided to put back the old RAM - still no working Battery.
Reseted the SMC and the NVRAM 500 times and nothing changes.
Already have the latest Firmware (Efi and SMC) for quite a long time, can`t reinstall it or downgrade it (due to apple.). Apparently CD firmware restauration not available to my model ( original installation cd don`t work beacuse it is a previous version of firmware?)
What else can I do?
Is there any way to force a firmware installation ?

2010 Macbook Air with 4GB RAM or 2011 Macbook Air with 2GB RAM

So I am looking a the following 2 Reforebished Macbook Air models:
Refurbished MacBook Air 1.6GHz dual-core Intel Core i5
http://store.apple.com/ca/product/FC968LL/A
Originally released July 2011
11.6-inch (diagonal) high-resolution LED-backlit glossy widescreen display
2GB memory
64GB flash storage
Thunderbolt port with support for up to 2560-by-1600 resolution
FaceTime camera
Intel HD Graphics 3000
$789
Refurbished MacBook Air 1.6 GHz Intel Core 2 Duo
http://store.apple.com/ca/product/G0JK0LL/A
Originally released October 2010
11.6-inch LED-backlit glossy widescreen display
4GB memory
128GB flash storage
NVIDIA GeForce 320M graphics
FaceTime camera
$799
So my main question is which is better, the core 2 duo with 4GB of memory and 128GB of storage, or is the intel core i5 with 2GB of memory and 64GB of storage better? There is only a $10 differnce so the price doesnèt matter to me.

i would go with the one with more RAM and larger SSD.
Simple reason - you can't upgrade it in the future.
Sure the other one has a faster processor but what's the use of having a faster processor if you only have 2GB of RAM?
The other one is newer, but again, you can't upgrade it.
That's the reason why it's also cheaper........

MacBook not booting after RAM upgrade

I'm sorry if the case has been already posted.
Yesterday I took my MacBook Alu unibody late 2008 to a RAM upgrade (from 2 to 4gigs) to an offical Mac Reseller. They installed it and showed me that the system loads properly and recognized the new RAM.
I took it home, started working on After Effects and Photoshop and when i wanted to check a video on Quicktime, this program refused to boot.
Then photoshop freeze and after effects did so. I quited all aplications and restarted. On restart after the 'bong' i've got the grey screen white an apple logo and a loading bar underneath, that was it, it never finished loading but shutting down.
After the 2nd try the computer gave me the BAD RAM alarm signal right before the start button was pressed and nothing more. I just managed to start it ONCE on safe mode, but this one also freezed and colapsed.
Today i didn't get the BAD ram alarm but the grey screen and loading bar after shutting down.
I took it back to the reseler, the shop boss who did the upgrade wasn't there , the guys on the morning shift placed the old RAM back resulting the same. So they told me it's a software problem, not hardware and might be caused by a failed firmware update or something i did wrong and since i was showed that the system booted after the upgrade i can't complain or argue that they did somethiing wrong.
So basically the want 80euros to check what's wrong with my computer plus the 120 i already payed them for a RAM that doesn't work and of course the repair cost of the computer.
On monday i'll go to talk to the boss, what do you guys recomend me to tell him? i'm frustrated that the guys there treat me like if i broke my computer for beeing stupid and wanted to get it fixed for free, when it clearly broke after they did something wrong on it!
please advice me!
thanks!

What brand is the RAM? From what you said, it is obvious that the RAM is at fault. I would simply tell them that it is not compatible and return the RAM.
Check the System Profiler to see what it says about the RAM (Apple Logo - About this Mac - More Info) and run this application to test the RAM:

If either shows any errors, print out the results and take them with you to the store.

Garageband on Macbook not recognising Tascam US 122

I've downloaded the latest drivers from Tascam and connected the US122 to my intel macbook. The US122 is recognised as a USB device as all the lights are showing and phantom power ia available. In Garageband preferences however it doesn't show in the list of input devices.
Any ideas?
Cheers
Dick

I had a similiar issue and I don't totally remember how I solved it. I hate to say it (bc it's probably been done and they always start out this way on the phone), but:
make sure to restart
try another usb cable
if you are plugged into a hub, try a direct connection to the mac
there was also a note in the install to disconnect the US122 before you go through the install process. I didn't see that the first time through. I don't recall if that was the piece that fixed it. There seem to be a lot of people in forums all over the place that are having diff problems with this interface.
best of luck.
cheers

PSE 11 not recognising extra ram on an iMac

I have an iMac which had 4 gb of ram. Photoshop defaulted the usage to just under 3 gb. I installed another 8 gb of ram but PSE fails to recognise the extra ram
so I can only get it to use 3gb. If I reinstall will it recognise all my ram? Will I still have all my photos on the organiser?

Hi smudger1939,
PSE won't recognize the extra RAM after 3072 MB. As it's the highest which a 64-bit application can use. So even if you install even another 16GB of it. I won't be able to use that one. However, it's a benefit when you are using several applications parallely. The extra RAM will be used by other applications, and will not hamper your PSE performance.
So if you want to increase the performance of PSE, reduce the history states. You can also refer to this kb article for the same:
