2Gb Memory Modules - Power Mac G5?

New here, but a returning Mac user.... at last....
Just got hold of an older (early 2005) G5 Power Mac (Dual 2.7Ghz). Can anyone tell me if it's OK to upgrade the memory using 2Gb memory modules (assuming of course I have matching pairs, and don't exceed the max memory - 8Gb I think)?
Sorry, I'm only able to find that 2 x 1Gb modules is OK, but so far nothing on 2 x 2Gb modules...
Thanks.

2 x 2Gb modules will not work.

Satellite Pro P100: What is the Toshiba part number for a 2GB memory module

Unable to find any way of emailing this question so I have posted it on the forum. Sure this info should be more readily available without having to ask.

Crucial Memory gives me this module - is that correct?
http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=A332E10BA5CA7304
Found this via Kingstons site - is this also correct?
http://www.dabs.com/productview.aspx?QuickLinx=4P3V
Would really appreciate some official clarification here.
Many Thanks

It must be PA3513U-1M2G. You must check if this module is compatible with your notebook model. I think so.
Anyway I recommend you to buy high quality product like Kingston modules.

Macbook Pro Core Duo 2.16Ghz with 1GB+2GB memory module

Is it possible to install an 2gb modulle along with my 1gb module witch came standard with my macbook pro Core Duo 2.16Ghz?
Im thinking about the following modulle:
Kingston KTA-MB667/2G
(Any other suggestions?)
And just for my information is it possible to install 2x 2gb memory?
Thanks!

But i still have a few questions:
Is the 2gb modulle not supported or the total of 3gb
is not supported?
I want to know it absolutely 100% for sure becouse i
would love the 2gb addition. And i don't want a buy
something wrong :P
From what I have read in various forums a single 2GB module will work in the Core Duo machines. 3GB is not supported however. People who have tried adding 3GB (2GB +1GB) to a Core Duo report the computer would not boot.
I am not sure why you would want to use a single 2GB module though. Perhaps if you were wanting to upgrade to a Core 2 Duo later?
I would say if your going to try to use a single 2GB module understand the risks. i.e. I don't how much people actually tested for stability etc. other than to try it and say yeah it works. You do loose the dual-channel configuration for whatever that is worth.
I would make sure you purchase from a place that has a liberal return policy if your going to try it. Just in case your not happy with it.

Memory on Power Mac G4

How in the world do you determine how much memory is available

Click this... go there... get info...!!
Your remaining capacity is shown in the bottom of every finder window

HT1423 Purchased 2x2GB Memory modules, and installed . No dock , no Menue bar??

What to do??? Purchase from Apple On-Line store 2x 2GB memory module. at appears iMac does not regognice the new memory.
Mac OS X asking for pass word, still running on Snow leopard.

You probably followed these steps to install the memory: http://support.apple.com/kb/HT1423
Since you have an Intel iMac, reset the SMC and PRAM:
SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
If the iMac doesn't recognize the newly installed memory after doing that, reseat the memory and reboot.

Satellite L40-14N won't start up if i install two 2GB RAM modules

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
mansy

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.

Is it right to mix sizes of memory modules in a mac mini 2012? for example 2Gb 8Gb?

Is it right to mix sizes of memory modules in a mac mini 2012? for example 2Gb 8Gb?

Welcome to the Apple Support Communities
You can do that without any problem, always that the total amount of memory is less than the maximum memory your Mac mini supports. A Late 2012 Mac mini supports 16 GB of memory, and you can find in this site the steps to install more memory > http://support.apple.com/kb/HT4432?viewlocale=en_US&locale=en_US#1

Upgrading 1.8 MHz Power Mac G5 (memory and OS)

I recently purchased an iMac loaded with Leopard. I would like to use the install disk to upgrade my older Power Mac G5. My machine is running 10.3.9 currently.
I know I need to increase memory, but by how much? A salesman sold me additional memory some time ago, but it caused a lot of problems and I removed it. Now I'm leery of what to buy. Will the following memory description be appropriate, both in type and quantity to run Leopard?
1GB PC3200 DDR 400MHz Module For PowerMac G5 Models(requires pairs!), iMac G5, Mac mini 1.25GHz/1.42GHz Models. TRUE PC3200 CAS 3.0(or Faster) Non-Stacked 64x8 device Low-Noise PCB Solution! New, Lifetime Advance Replacement Warranty. (OWC3200DDR1024)
My Power Mac's memory currently consists of 2-128MB DDR SDRAM PC3200U-30330.
I'm application-oriented and not too technically savvy.

The G5s came stock with 256MB 6 yrs ago but even then it was sub-standard amount and 1.2 - 1.5GB RAM was much better for even basic light use.
2GB should be a good improvement, you have 4 DIMM slots likely. But it depends on what you plan to do or use it for. Buy from vendors that sell and cater to Mac hardware.
OEM DVDs like from an iMac can't be used, they don't load sometimes, and you really do need retail discs. Good luck finding 10.5.x DVD retail.
New drives can also do a lot to improve performance.
Realize though, other than running older PowerPC applications, the iMac should be able to do most things very well.

Upgrading an early 2005 G5 Power Mac - memory & HD - your hindsight appreci

Hello, I have an early 2005 G5 Power Mac, dual 2.3 Ghz, 2GB memory, and a 400GB Hitachi Drive.
In researching memory and hard drives, I come face to face with all the engineering terms and now have cold feet about it.
My existing memory is called: PC3200U-30330 DDR SRAM. I found a Samsung module on the web called a PC3200 DDR400 for $61 but the vendor won't confirm compatibility. Can anyone recommend a competitively priced substitute for the expensive Apple part? Is there a rule of thumb on knowing how much is too much or should I just buy 6 additional 1GB modules and have done with it.
I have one HD. I assume it is a SATA-1. I'd like to buy a 500mb 2nd drive. I have read the SATA-2 drives are backward compatible; are they? How should the jumper on the new drive be set: cable select??
Finally, are there any performance suggestions anyone could mention for me to look into? I am editing music files in the 10 to 75mb range, cutting and re-constructing movie clips in the 4.7 gb range.
Thanks in advance for your suggestions,
Sam

Hi,
the RAM compatible with your computer you can find here:
http://eshop.macsales.com/MyOWC/Upgrades.cfm?model=219&type=Memory&TI=1906&shoup grds=Show+Upgrades
And also on other Mac's sites like Crucial, Omni Technologies
I would be very careful with PC's RAM - some of them can work with Mac, but some don't.
Hard disk SATA-2 is backward compatible, so you can buy for example Maxtor MaxLine Pro 500 GB:
http://eshop.macsales.com/item/Maxtor/7H500F0/
or WD RE2 500 GB:
http://eshop.macsales.com/item/Western%20Digital/WD5000YS/
or Hitachi:
http://eshop.macsales.com/item/Hitachi/0A31619/
I think that you don't need more then the next 2GB of RAM. In fact, if you editing music - your current 2GB seems to be fine. But always 4 GB is better then 2 GB
And performance suggestion in this case is faster processor - so, you can buy used Quad G5, or better MacPro 3.0 with 2 GB RAM.

Power Mac G5 (late 2005) memory showing two different speeds

Alright, here's the situation. I have a late 2005, Dual 2,0Ghz, water cooled, model, G5 Power Mac tower. These have 8 memory slots, (1 upper bank of 4 slots and one lower bank of 4 slots located directly above and below each other on the motherboard). The two inside slots (the two slots that are closest together - one from each bank) are labeled slot 1. Then the next two slots (moving outward from the middle) are slots 2, then slots 3, then slots 4. Anyway,according to the Apple specs, the memory should be set up in matching pairs of like modules: i.e. slots one = 2 X 1GB sticks of matching PC4200, slots 2 = 2 matching sticks of PC4200, etc., etc, up to a total of 8 GBs of compatible memory.
I have 8 X 1GB sticks of "matching" Kingston PC4200 memory installed, and it even shows up on the "About This Mac" page as 8 GB. However, if you take this one step further and proceed to the "More Info" page, under the "Hardware" tab, the "memory" info it shows up as 4 sticks of DDR2-PC4200, and 4 sticks of DDR2-PC3200. Ironically, slots 0,1,2,3 indicate as PC-4200 (533Mhz), and slots 4,5,6, & 7 indicate as PC-3200 (400Mhz). Can anyone give me some insight as to why this would be happening? I've also re-arrainged the memory modules, but the memory speed discrepancy stays the same.
Any help would be appreciated!

It's likely no problem if everything is running fine, some SPIDIF chip anomoly I think.
I've read several problems with Kingston RAM in Macs.

Can i use 2gb memory in one slot in my 2006 Mac mini as the 2 slots of 1gb only reports only 1gb memory, both memory work ok in the one slot

Can I use 2gb memory in one slot in my 2006 Mac mini as the 2 slots of 1gb only reports as 1gb memory, both memory work ok in the one slot as I have swapped them over

To my knowledge 1GB modules are the max. size for the 2006 Mini.
2GB modules are not recognized/useable.
Sorry

Powe Mac G5 early 2004 gives error (no memory installed) Do I need to replace the Logic Board. Machine powers up,2beeps and power lights blinks 2 times and stops there, No video or any thing?

I just recently aquired a Power Mac G5 early 2004.
When I power the system up. I get 2 beeps
and the small front panel light blinks 2 times continuously.
The error codes show that it means a memory problem or
no memory present. Memory is installed.
In this case do I need to replace the mother board.
The system goes no futher, no video or any thing.

Well, it's possible that someone pulled the original RAM from the computer before they sold it, and repalced it with incompatible RAM. That, believe it of not, would be the best of all world in this case, as a working G5 logic board and its installation could cost as much as a refurbed Intel mac.
I would contact the seller if you did not personally see the computer working before you bought it.
As the computer had to be moved about--possibly shipped--to change hands, first check that all internal cards and RAM Modules are fully seated. They can work loose in some models.

Power Mac G4 bluetooth module

Hello,
I have a dual 1.42GHz model FW800-equipped Power Mac G4 (the fastest G4 Apple made.)
I bought it, and it's like it's never been opened! The original Pioneer Superdrive is there, original Seagate 120GB HDD (with a  logo on it),
original 2x256MB Samsung RAM sticks, and the Radeon 9000 Pro, and everything works fine.
I'm in the throws of upgrading it, and I have got 2GB of RAM, and Tiger on it so far.
I have found the original Service Source online, and it shows how to replace an internal Bluetooth module that was apparently an option on FW800 G4s.
It connected to a little blue antenna cable (that my tower has), and connected to the logic board via a little connector (that my tower also has) between the AirPort Extreme slot and the 56k modem.
With this info, my question is-where can I get one?
And before someone writes this, no, I don't want a cheap external dongle. G4's have only 2 USB ports as it is, and I don't have a PCI card.
Thanks!

I don't have a PCI card.
Get one.
More precisely, any NEC chipset USB 2.0 PCI card is great in OS X Tiger and Leopard (native NEC chipset support).
Some considerations are discussed on my page that follows:

You can get a NEC chipset PCI card for just a few dollars..... good, cheap upgrade.
