Installing extra 2gb of ram?

probably a stupid question but what cofiguration do i add an extra 2gb of ram (2 x 1gb = 4 x 1gb in total) to my Mac Pro?
I originally got an extra 4gb but the seller gave me 667mhz eram so he just swapped it today for 2gb instead.

Yes, that is the way Apple ships it, and is different from older Mac Pros.
You have a choice: move the one from B to A2, or put the two new DIMMs in slot 2 on each.
Dimm slot one and two have to be identical matched, same size.

Can i install over 2GB of RAM?

my company accidentally bought some extra ram for our macbook pro's, and offered the old 2GB sticks to me. what would happen if i put (2) 2GB sticks in my macbook? i know it's over the max (and i assume that it wouldn't be able to access it), but would it work? would it effectively function as the max 2GB? most importantly, am i going to harm anything?

It is a Core Duo (not Core 2) and 2X2 Gb works fine? This link and OWC say otherwise

Hey there cutyscar,
It sounds like you are unable to connect to your router either by Wi-Fi, or ethernet. I would recommend trying the troubleshooting outlined in this article named:
Mac OS X: Troubleshooting a cable modem, DSL, or LAN Internet connection
http://support.apple.com/kb/ts1317
Start with this step, and work your way down as needed:
Check all cables and power supplies
Make sure all the cables related to the modem are plugged in and firmly inserted. This includes the modem's power cord, the cable from the modem to the computer, and the cable from the modem to the outlet. To be sure a connector is properly inserted, disconnect and reconnect it. Check to see if the cables have been cut, chewed, or otherwise damaged.
If you have any hubs or routers, check their cables and power supplies. If you have more than one power supply available for a type of hub or router, try swapping the power supplies. A defective power supply may affect network traffic.
Thank you for using Apple Support Communities.
Take care,
Sterling

Problem installing extra RAM

Hi,
I recently decided to increase my RAM. I have an iMac G5 with iSight ( Power PC ). I bought a memory module from the online Apple Store here in the UK, by clicking on the model ( under Memory ) and selecting the 1 Gb module - 533 Mhz DDR2 SDRAM ( it made no specific mention of the PC2-4200 compliancy but I assumed it was the right one given the route I followed ). It duly arrived and I installed it by following the manual. However, on checking About This Mac the extra RAM was not registering, ie still showing the original 512 Mb RAM. I called Apple Tech Support and we tried a few things like resetting PRAM etc,but no change. Eventually, I was put on to sales and arranged to retunr the module and get a refund. I got the impression by the way the conversation went that this was not the first time this had happened.
So, no extra RAM. Anyone tried to install extra RAM in an identical model?And, if so, did they get their module from Apple? I'm assuming this is nothing to do with the fact that I have a Power PC model and the current models are all Intel?
Any help and/or advice would be much appreciated.
Thanks

Any RAM can be faulty, and I suspect the one you got from Apple was. Go online and Google for PC2-4200 (533MHz) DDR2 SDRAM memory. Kingston is a good brand and should come with a lifetime warranty. Most RAM from sources other than Apple is cheaper as well. The RAM you bought is correct for your model, and make sure that when you instal it, you hear it click into place.

HT3918 Can I leave the installed 4gb (2 X 2gb) of ram in my iMac and add 8 gb (2 X 4gb) of additional ram to the available (empty) slots?

Can I leave the installed 4gb (2 X 2gb) of ram in my iMac and add 8 gb (2 X 4gb) of additional ram to the available (empty) slots? I will ultimately swap the remaining 2 X 2gb out for 2 x 4gb. If so, does this affect how the ram is used/accessed (i.e. will the original ram be limiting because it is in the installed location rather than in the other previously open slots?) Thanks.

That's exactly the RAM arrangement I've been running with for the last couple of years with no issues.

Computer won't start up if i install two two gb ram modules,can i install vista 64 on this computer to overcome this problem,have upgraded bios.or is there something else i can do.it also wont work if i put a 2 and a 1 gb ram in.
Any help would be apprecated

No, Vista 64Bit won't solve your problem. The fact is, that this notebook model only supports a maximum of 2GB Ram in total. So, you can only use one of your 2GB memory module.
If you do so, notebook will boot up again.

Tecra 9100 - Installed extra 512mb RAM but it's slowed down my computer!

After much fumbling around trying to install my new 512mb RAM, I switched on my computer to find it boots much slower. A message popped up saying 'Memory Module Added' and my computer shows that 768mb is installed which is correct because I already have 256mb installed in Slot 1.
So why on Earth is my computer even slower!? I bought it to speed up the thing! My computer is slower to boot, is less responsive and much better off with just the 256mb of RAM installed.
I think I might have damaged the RAM or Slot 2 because at first I inserted it in wrong. They should have made a video demonstration on how to install it because the manual didn't help me that much!
The RAM is from Crucial and supports my laptop because I ran the tests to decide which RAM I need.
Can anyone please help me!

I'm a bit puzzled as to why your laptop would slow down after a memory upgrade. Like Kingston, Crucial is a recognised brand and therefore you should have no compatibility issues. The memory will tend to run at the speed of the slowest module, as is the case here.
While a properly earthed anti-static wrist strap may be the ideal procedure, I usually rely on earthing myself on (say) an appliance which I know is fully grounded immediately before touching a memory module. Alternatively a radiator or other item which might be earthed. Of course this depends on your countries electrical regulations :-)
You must avoid touching the contacts or surface - always best to hold the module only by its edges.
As another poster has suggested, remove the 256MB module and replace with the (new) 512MB Crucial module and check the laptop boots OK with just the 512MB module. A symptom of bad memory is when it causes the PC to fail to boot or the PC freezes at any point (either within seconds or after a period of time).
If this fails, then download the memory diagnostic tool from Microsoft web site (you may want to do this from another PC). I cannot remember the full name or URL, but it is the one recommended by XP when a memory-related error is reported. The software extracts to a bootable floppy or CD and carries out a very comprehensive memory test.
Let us know how you get on.

Looking for 2GB of ram to upgrade my hp pav 20-b010z all in one

I am trying to find just 2GB of ram so I can upgrade my HP Pav 20-b010z all in one computer. My product # C1A32AV#ABA. It only came with 2 GB.
I have DDR3-1066MHz SODIMM Memory and Windows 8 64-bit. I only have one stick in the computer. I was told that I need to use PC3-12800. I'm pretty new to all of this.
Could someone please tell me what kind of ram I need to use that would be compatible with my computer. What brand too, please. If there is one by HP I would gladly like to use that.
Thank you for any help you can provide

Hi:
Please take a look at the product specs for your PC at the link below.
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03569440&tmp_task=prodinfoCategory&cc=us&dlc=en...
The PC3-12800 memory downclocks to 1066 MHz (PC3-8500).
You can install up to 16 GB of memory in your PC.
Why do things half measure? 4 GB is the minimum memory I would run a 64 bit OS on, and have it work acceptably.
I would just buy 2 x 8 GB of PC3-12800 memory and have all the memory you'll ever need, and get it now while it is cheap.
Here is a link to a place where you can get good PC3-12800 memory cheap.
I defaulted the search to PC3-12800. You can refine the search by clicking on the memory size, etc on the left side of the page.
Read the reviews and get what makes the most sense to you.

Can I install a 2gb Sata3 HDD in my IMac G5 20" ALS?

I currently have a WD 2gb Sata2 HDD drive in my machine which is probably going to crash soon due to a node error I get when running disc verify in disk utility. The machine was running very slow recently which prompted the verify disc. I have 2gb of RAM running also.
The local shops only seem to sell Sata3. Can I install this drive or do I have to source a Sata2?
Many thanks
Mdn

Node issues can be fixed with booting from the 10.5 retail installer and running Disk Utility from the installer's Utilities menu to Repair Disk. If that can't repair it, backup your data, and purchase Alsoft Disk Warrior. If that can't repair it, yes replace the hard drive. Faster SATA hard drives can be put in, if they either have a jumper than slows to 1.5 Gbps, or are designed to automatically downstep to that speed. Check with the manufacturer if that's a possibility for the model you are looking for.

Macbook Pro freezes after installing new 4GB of Ram

So I have a 15" macbook pro (2.4Ghz) that I've had for a few months. It's been pretty good so far, but I've been using it for Ram-intensive programs such as Adobe Photoshop and Illustrator, as well as Logic. I only had the 2GB of Ram that it came with, and I was noticing some latency. So I did what everyone recommended and upgraded the Ram to 4GB. I purchased some at my local computer shop (s598: Super Talent 4GB SODIMM DDR3 1066Mhz) I just posted the exact numbers posted on the packaging for this item. I know I need DDR3 1066Mhz, but I'm not sure what the S598 stands for.......
Anyhow, I just installed this today. And it seems that the system doesn't get bogged down AS much. But my laptop has COMPLETELY frozen up twice within a couple hours and I've had to force shutdown the machine... Is this the RAM causing this?? Would anyone know if installing this Ram can be problematic? Any help would be appreciated. Thanks!

All of the new unibody MBs/MBPs can use (6GB 4X2GB)
But yes you should definitely make sure the RAM is seated correctly and you didn't touch the gold part of the RAM during installation. Though if something was seriously wrong it would have made loud obnoxious sounds while you tried to start up.
Aside from Installation issues, you should reset the PRAM as noted previously. Hold down command-option-p-r at startup until it chimes twice.
OP, looking at Super Talent's website they don't even have 1066MHz chips listed in their DDR3 chips. All I see is a jump from 800MHz (DDR2) to 1333MHz (DDR3).
Either way, I can't imagine you got that great a deal for the RAM that even if it is seemingly the correct RAM you can get better deals in the links I posted in my other post.

2GB of RAM missing after 10.6.5 update

I updated my Mac Pro (8x2.8GHz) to 10.6.5 today, and I'm now missing 2GB of RAM. Here's a line from Console.app this morning when I installed some software (not responsible for this):

And here's a line after I updated:

Where has my 2GB of RAM gone?
Looking in the System Profiler, the correct 6 DIMMs are there, but two of them that should be 2GB are now showing as 1GB. I had 4x2GB (from OWC) and 2x1GB (Apple-supplied), and now I have 2x2GB and 4x1GB.
Much woe. Please help...! Thanks!!!

Marginal RAM.
Replace, or try reseating; also SMC Reset.
Almost every OS update has 'broken' or revealed marginal hardware (RAM, video card, etc).
Rather common as in, this does get reported with RAM not showing up in Mac Pro, from time to time over years affecting users.
FBDIMMs such as yours run hot, need cooling, age? prematurely. Keeping them as cool as possible, even below recommended standards, helps, say below 74*C and hopefully in 60's.

I bought this MacBook Pro 15.4" 1.83 GHz MA463LL/A with 2gb of RAM for real cheap on eBay because I'm poor and can't afford a new MACBOOK PRO and was wondering what everyone thinks about these laptops and what can and should I upgrade when I get money?

I bought this older MACBOOK PRO 15.4" 1.83 GHz with 2gb of RAM and Leopard 10.5 on eBay for real cheap because I don't have the money to buy a new one like I would like to do, and it comes with a disk to upgrade the OS to 10.6 and I was wondering what all I can and should upgrade (short of the whole computer) as I have the money to do so? Or did I just get really hosed?

You have the original Core Duo model. 2 GBs is the most RAM you can install, so the only thing you could upgrade would be the hard drive. Doing so is not a trivial task but you can find suitable hard drives and installation tutorials at OWC.
Since yours is a Core Duo model you can upgrade OS X to Snow Leopard, but not to Lion which requires a Core 2 Duo or better.

How do I know they really installed 2 GB of RAM?

Here's what happened and why I ask:
Computer is back home after spending the better part of a month in an authorized Apple service center shop. Took it in to upgrade RAM from 250 MB to 2 GB. A routine procedure I was told that would take no more than an hour. It's been a computer nightmare.
First, the shop had "issues" installing the RAM. Then, while trying to do so, the logic board "failed." They got a new logic board. Brought it home. Trouble and back in. Incredibly, that logic board failed. Installed another one. More problems, highlighted by "kernel panics," the CD drawer not opening, and other things. Back to the shop where they say everything's been fixed. CD drawer needed a "new cable." Don't know what they did to fix the logic board/RAM thing. All things thoroughly checked and machine is working perfectly. Incidentally, I was not charged for any of these "extra, unanticipated" things.
I don't know yet whether the computer is really fixed. Starting to use it to see if it really works. After about a day.....no apparent problems. We'll see. But,
How do I really know they actually installed the 2 GB of RAM. The reason I ask is that after one trip in and back home, I noticed that the computer's serial number did not show up in the "About this Mac" and the Macintosh HD info window. After telling them that, next time I brought it home, sure enough ... the was the serial number showing where it was supposed to.
Appears to me they knew how to type it in and did so. Couldn't they do the same thing with the RAM info? Because the computer seems to be working ok after one day, could they have taken out the 1 GB RAM chips or boards or whatever they're called (because they just didn't work), and re-installed the 256 MB one? Then just typed in the info for 2 GB RAM boards in the "More Info" window of "About this Mac."
And...........I notice no difference with the apparent 2 GB of RAM compared to 256 MB. Shouldn't I realize something? More speed in working with applications? Or something? How do I know they actually installed 2 GB of RAM?
Thank you for your thoughts.
(Obviously, not I'm not a computer whiz.....don't know a logic board from a chess board–although I've learned it's a pretty important component.)

Firefox is free (Mozilla/Firefox) and in some cases it appears to work
quickly for some web content; I use both, Firefox mostly, then Safari.
GarageBand can be a CPU-intensive application; depending on what
you are doing with it. Composing music and layering effects could do it.
To supplement chip RAM, you'd likely need a larger capacity hard disk
drive and leave more free space for both the application to run and also
to have room for larger demands of the system; virtual memory mainly.
Newer drives also have larger buffers, so one with a 16MB buffer could
also add some speed too. The stock 80GB drive 1/2 full could be slow
since your computer would be read/writing more often to the drive as it
is used more and more as virtual memory and also to record changes
to your GarageBand music compositions; plus normal system demands.
Of course, you could use an external FireWire enclosure and put a much
larger hard disk drive into that; large enough for a full system clone and
then boot from the external when doing things such as GarageBand; the
work you do would be saved to the external and its system would be
like having a second computer, booted and running from the FW HDD.
There may be better ways of doing this; one may be to consider a Mac
with faster bus, processor, RAM type and speed, among other upgrades.
Upgrades involving service tech access to the iMacG4's base unit are
to be done in the proper way so as to be sure the thermo paste and other
safeguards in the cooling system (heat scavanging is essential) are
restored properly when the machine is reassembled. Some upgrades to
these computers can add more heat-generating capacity, so cooling is
essential to reduce the odds of probable failure from overheating; since
the processor, more RAM, and a busy hard drive add up.
If the machine is used in a warm room (a dusty/smokey environment)
these details will add to higher heat output of the computer; in that
it won't be as cool as it could be. Of course, in this matter, you could
get a sensitive thermometer with a sensor and put the sensor near the
computer's air output to get a second comparative heat gauge on it.
Not just the Temperature Monitor software's take on internal heat.
If the machine should overheat, it will affect more than the recordings;
and how the computer's resources are allocated to tasks and the effic-
iencies (or lack of) in how they are used will affect applications, do have
an impact in a wider range of overall machine health.
The Activity Monitor can help, in that you can monitor and see what is
going on inside the computer and maybe control system resource use
by not multi-tasking when using a major application. There may be a
way to allocate system resources to your primary application in use,
but in OSX that is fairly automatic (unlike older OS9's RAM use.)
In Discussions, there is an area for Application discussions and
perhaps more detailed replies from knowledgeable users of Garage
Band would be generated from questions you may have, in there(?)
I have GarageBand, and recognize its value, yet seldom use it.

2006 model iMac, is it worth putting in 3 GB over 2GB of RAM?

I currently have 2GB of RAM installed as 2x1GB chips. Is it worth bumping the memory up to 3GB (Apple said I can put in 2x2B chips but it will only see 3GB)? Will I notice any difference or is the 2GB pretty much the sweet spot? Thanks.

Hi nflp
What does your Activity Monitor tell you after an hour of normal use?
http://support.apple.com/kb/HT1342?viewlocale=en_US
If your running a lot of big app's at the same time and your running low with 2 GB them yes 3 GB would be better.
Except that ram is cheap and 4 GB would be even better, because your system would access 3.3 GB of ram and maintain the matched ram performance.
