2,2 GB RAM usable out of 4 - iMac

Hey! I have an iMac from late 2011 it has an Inter core i5 processor and 4 GB RAM, wich only 2,2 GB out of 4 is usable. I also have 32-bit Windows 7 if that does matter. Why is only 2,2 GB out of 4 GB ram usable? It's been like that as long as I can remeber and what can I do about it? Thx

Lion can use almost 4 GB by itself for the OS, as BDAqua mentions above. With only 4 GB of RAM installed in your iMac you may be throttling the system speed and performance. I would recommend that you consider visiting a site such as:
http://www.macsales.com
and let that OWC site recommend the amount of RAM that your model of Imac is capable of installing. RAM is very cheap these days, OWC is highly rated by Users in these Forums, and any increase in the amount of RAM you can use will help speed up your system noticeably; the more RAM, the faster you go.
Hope this helps

HI
Ensure that your Graphic Card is not sharing the memory with RAM, It could be one reason so get it checked and if yes, the reduce the memory on BIOS for Graphic Card

Why is only 2.73 Gb of RAM usable on a 4 Gb RAM MacBook on Windows 7 32 bit

I understand that with the video card (which is 256 mb of dedicated RAM on this model) I should have ~3GB of RAM usable on 32 bit version of windows 7. (Yes it is legal, which seems to be the first question in this discussion)
Is there something else in the equation that I am missing?
1. 32-bit only applies to RAM over 4 gb and since this is bootcamp, it is not running another operating system.
2. Unless there is something within the hardware of my macbook that is only able to use 3 Gb I apologize for my ignorance, it's not really a serious issue but I could almost swear that I had more memory usable on my windows 7 partition at one point in time.
Thanks in advance

bump?

HT1423 i am replacing ram in an early 2009 imac. easy - right? but the pulling on the tabs didn't work. i have had the ram sticks out before; but now they don't budge. should i apply more pressure? use a tool to pull harder? will the tabs break off?

sorry for the format - my 1st question...

thanks Kappy.
the computer has beem working for years after my 1st ram removal; but i may have pushed them back too hard. i did pull firmly - tried pulling up slightly; tried tugging on the sides of the stick; pulling in pulses. the only thing i have not tried is using needle nose plyers with protection on the tab film itself.
have you had the pulling harder ever work? or break the tab?

MSI 970A-G46 Ram Usable Issue

So the problem is that everytime I shut down my computer and then turn it on the next day, I have to enter BIOS to change the ram usability (In Computer -> Properties) from 7.97gb to 16gb .
When I turn on my desktop and go into properties, it shows that 16gb is there but only 7.97gb in parenthesis is usable .
It's really annoying to have to enter BIOS to change this everytime and thats just it, I set it to link and 1600mhz in the BIOS and the settings don't change, I just to have physically enter BIOS every time I start and hit save changes (I don't change any settings, I just have to save it every time) .
Mobo - 970A-G46
Memory - 2x8gb Patriot 1600mhz
Cpu - AMD FX-8350
Windows 7 Ultimate

Clear CMOS: >>Clear CMOS Guide<< then try aagin without changing settings. If no help what bios version is installed?

Ok, so i bought a imac 27 about 4 months ago, and now they release a new one! ****... So my question is, should I sell this one (which by the way is the i5 2.8 with 1 gb 5750 and 4gb ram) and buy the new imac 27 i5,or keep the one i have and buy more ram

I mostly use my computer for photoshop cs5 and illustrator cs5 for graphics out put as well as surfing the web and music.
Please give me you thoughts on what I should do!! Thanks lot!

The new iMac is about 25% or so faster than your current iMac(comparable model would be the 3.1ghz version). There are a couple of things that you will benefit from such as the dual Thunderbolt/Mini Display ports/ which may help with multitasking. The video card in the new iMac again the comparable model being the 3.1ghz is a lotttttttt better than the current one that you have. So thinking of the long run those few things may be beneficial for you to upgrade(but it depends on what is important to you).
I had the 2.93ghz i7 version that I just bought in March this year and I turned around and sold it about a week before the new iMac's were announced. I got about $1600 for it, yeah I took a loss but to me it was worth it because my new iMac performs that much better. Now keep in mind I went from i7 to i7...3.4ghz i7 with the 2gb video card. Now I have dual thuderbolt/mini display ports. I have noticed significant gains in my video editing and also in my gaming. So to me it was definitely worth the upgrade!
One last thing, I would not have sold my 2.93 i7 and then bought the 3.1ghz i5, the big reason is because HT(hyper threading), it's only on the i7 model(3.4ghz)... If you take a look at some of the bench marks on engadget, maclife, macrumors, macworld, ****Barefeats.com(they really get into benchmarking)*** you will see charts that will help you make a better decision.
In closing I would say look into it, if you can get a good price out of your current iMac to put toward a new iMac then do it. Like others have mentioned to you, tech changes and Apple will change the tech in these machines next year or do a speed bump later this year or so. One last thing if you go from the 2.8 i5 up to the 3.4 i7, you would definitely see the difference (HT is a must especially for programs that utilize it. You can go to my youtube channel(mob1278) and take a look at my geekbench results.... my 2.93 i7 scored around 10500-11000(8gb ram)...my 3.4 i7 scores from 12700-13000 with 4gb ram....so yeah as you can see big difference. Basically the 3.4 i7 would perform similar or just under a 2.4ghz 8core 2010 Mac Pro which runs you about $3500 with no monitor.... it's your money spend it how you want....and Lion is only going to push it even more when it is released!

My Apple TV drops out when my iMac isn't connected to wifi yet my TV is connected to wifi. Also having issues with losing settings on Home Sharing as well. How do I fix these issues?

Whether I'm watching a movie purchased via my Apple TV or a movie stored on my iTunes app on my iMac I'm having constant issues with Apple TV either cutting out (randomly - not related to wifi) or not being able to access the 'My Computer' files when my iMac drops out the wifi connection because its in power saving mode. I also have issues with 'Home Sharing' settings having to be reset and sometimes having to unplug the Apple TV power cord and plugging it back in to be able to successfully reset these settings so I can get back to watching whatever it was I was viewing on Apple TV. My TV is connected to wifi as well so I'm wondering if there are any changes I can make in the settings of both my Apple TV and iMac or TV so that I can just select whatever it is I want to watch and be able to watch the entire movie or episode without it dropping out or having to keep flicking the mouse on the iMac to keep the computer connected to wifi? I love Apple products generally but Apple TV is proving to be a pain in the a**e lately. Hopefully someone can help me sort these issues out

Intermittent issues will point to a local network/wifi issue.
Reboot ATV and router, make sure both are up to date
Try ethernet
The home sharing connection will cut out if the iMac goes to sleep.

Troubleshoot video out on new iMac

I'm trying to connect a mid-2011 iMac to my TV. I have a MDP/HDMI dongle and an HDMI cable. I hook everything up and the iMac doesn't detect the TV as a display. I checked the cables and rebooted the iMac. Anything else to check?
I've done video out with older iMacs (pre-MDP) and never had a problem. I have no way of knowing if it is a cable or a port problem.
The MDP (actually Thunderbolt) port seems loose. Is this just the nature of the port?

Try connecting the cable and adapter only to the TV and turn on the TV. Then hot connect the adapter to the iMac. If the iMac still cannot read the EDID from the TV I would call Apple about warranty repair/replacement.

Swapping RAM between Mac Mini and iMac (both Late 2012)

Mac Mini = 1600Mhz DDR3 RAM, 8GB (2 x 4GB)
iMac = 1333Mhz DDR3 RAM, 16GB (2 x 8GB)
Any reason why I can't swap the two around? I essentially need more RAM in the Mini and less in the iMac. The thing that concerns me is that when I go to "About This Mac > Memory," the Mac Mini states "Your Mac contains 2 memory slots, each of which accepts a 1600Mhz DDR3 memory module." If I toss some 1333Mhz in there...
Would swapping them cause any adverse affects besides a slower speed (whatever that actually does from a user standpoint)?

A gain of 8GB for $125 kind of *****. However, your point has been well taken. As it happens, I did upgrade the RAM in the iMac prior and apparently missed the Mhz rating. Interestingly, the number I gave you for the 1333Mhz came from within the system profiler on the iMac and states "Your Mac contains 4 memory slots, each of which accepts a 1333Mhz DDR3 memory module." I figured that it would show me what it is designed to use here since the actual RAM is listed in the over tab. Apparently this reflects what is installed and not what the system was designed for. I cross checked what you said and of course, you're correct in that both Macs run the same RAM...which now means I get to decrease my iMac RAM and still spend too much money on an 8GB increase.

Is it possible to stop the system time outs on my imac ,i have tried 5 times in the last 24 hrs.each time it will go for maybe 3hrs and then times out.each time i have to start the download all over again,thanks,

Is a matching pair of Ram required to run an iMac 1.83Ghz Intel Core 2 Duo?

I have an iMac 17" 1.83Ghz Intel Core 2 Duo with the standard 512mb ram (2x 256mb) installed. If I replace one of the memory slots with one 1gb ram stick, and leave one 256mb ram stick (1.256gb ram total), will my system run properly? Will it run at its optimal performance level? Or will Installing 2 sticks of 512mg ram perform better?
Also, is 1gb - 1.256gb ram enough to run parallels (windows xp) smoothly?
Thanks in advance.

Crazy to buy a maxed out late 2013 iMac now?

Was waiting to see if there would be any update but alas, no. Not sure I want to be an early adopter of a retina 27" iMac. Looking at a nearly maxed out non-retina (aka late 2013) 27" iMac. Only about $400 less than similar equipped retina model. Am I crazy or what? Use is just home computing and home video/photo editing. I just looked at retina 27 in store. I can see the difference if I try I don't see point in waiting for next gen chips either.

I just did something similiar. I waited and waited for the Retina iMac to be released before I made my final iMac decision. I was on board for even max'ing out the Retina iMac until I learned it would not support Target Display Mode. I already own a Macbook Pro w/Retina. And while I understand not seeing 5k each and every time, I expected (current technology limitations or not) the Target Display Mode to simply reproduce the same resolution as the Macbook Pro when connected via Thunderbolt.
Once I learned that the Retina iMac did not work as a secondary monitor I made my Late-2013 iMac decision. I understand where you are coming from because I had the same 'fears'.
It kills me to not have the 5k version when it exists, but last year's version (including TDM functionality) fit my day to day needs better.

Many thanks.
With those symptoms, I'd try the following document:
