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.

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.

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.

Power Mac G4 MDD problems with Hardware test Memory errors

I have been troubleshooting slowness and unexplained lockups on my Power Mac G4 MDD. I've had the system since 2002. I tried to run hardware test (the disk that came with my system), and I get an error message at startup:
Invalid Memory Access at %SRRO: 00034870
%SRR1: 00003030
I run mac-boot, and get another memory error
Invalid Memory Access at:
%SRRO: 056106dc
%SRR1: 00003030
Does this mean my memory has gone bad? I don't get any other screens for testing hardware.
The lockups are varied, but many seem to deal with Safari. I have also repaired disk permissions and repaired disk. I then get security error messages when I restart, and I choose to fix them, and things are fine for a while, but then it slows down some and starts locking up again.
Thanks for any suggestions,
Marbot61

Hi Marbot61,
You might be interested in the thread "error when booting from AHT CD" on this forum. Since four different users have had the same error message in two days, perhaps ram chips are actually ok, and there is something else going on with the AHT CD boot process.

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.

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.
Marek.

Power Mac G5 Dual 2.5 freezes up, Power Mac G5 Dual 2.5 freezes up

Hello
I inherited a Dual 2.5 PPC Power Mac G5 from my sister. She was having problems with it suddenly freezing up. She replaced the hard drive but that didn't fix it, and sicne she had a newer Macbook Pro she gave up on it. When I got it I replaced the video card on it with an ATI Radeon, and it seemed to run fine for a while, and then the problem returned. It seemed to have returned after I did all the Apple software upgrades on it (It's running Leopard), but that might be a coincidence. I noticed under Diagnostics on the power up test that some RAM had failed. I also noticed that it was running on 1 gb of RAM even though 2 gb were installed. I removed the faulty Ram (4 256 mb dimms) and hoped that that was the problem. Unfortunately it wasn't. I also installed a temperture reading program. It showed that CPU A is running around 80 C at times and is usually about 10C hotter than CPU B. I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time and date, and took a look at the battery, and sure enough it was starting to leak (but hadn't leaked on to any components). I've ordered a new bttery for it.
I ran a check with Disk Utility and found the HD was ok, but permissions were a bit messed up. Disk Utility wasn't able to fix some of the permissions, but i don't think this is the underlying problem.
I've also opened it and gave everything a thourough vacuuming and cleaning and reseated any removable parts. I took the cover off the liquid cooling unit and vacuumed out the dust. There didn;t seem to be any coolant leaks I could see.
Any suggestions on where I should go from here? I unfortuantely don't have any of the disks for it, so I can't run the AHT until I find one for it (the one for my Macbook Pro wouldn't work).
Sometimes it just freezes. Other times it freezes and the computer fans go on high. It will finally get to a point where it shows the grey multi-language restart screen (where it says to hold down the button to shut it off and the restart).
It was frustrating because on my workbench it was running fine after I switched the video card, and it didn't freeze at all. When I moved it to our computer desk though, the problems returned. Tonight it was to the point where it didn't last 5 minutes.
My thoughts are:
1. Maybe All the RAM is bad
2. Maybe the dead battery is messing it up?
3. When it is heating up with use, something is expanding and not connecting any longer.
What are your thoughts?

Hi Curtis,
I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time
Nope, not normal, way too hot, above 70°C... If you have any temps in the 70°C/160°F range, that's likely it.
Have you blown the dust out of everything with high pressure air?\
1. Maybe All the RAM is bad
The Memory test can really only be trusted if it finds a problem, not if it doesn't find a problem.

Power Mac G5: A common dilemma: to upgrade or buy new

I know there are a lot of discussions on this topic going around, but everyone's needs and uses are different, so I'd appreciate any input on my situation.
I own a Dual 1.8 GHz Power Mac G5 with only 1GB RAM and a failing 160GB hard drive.
At this point, I basically only use this machine for web browsing, iTunes, and Garageband, and am running Tiger.
I had been having some major hard drive problems so I wiped my system and re-installed Tiger , importing everything from my iBookG4 (which, I recently dropped and the screen connection has failed and is unusable except for as an external hard drive in target disk mode. it is probably too expensive to fix for what its worth so I will probably try to sell it for scrap).
Anyway, everything was ok for about a week until I opened firefox and noticed all my settings and bookmarks were gone. When I restarted my computer, my music, pictures, documents, and movies folders were all unable to be located (although my applications were fine and my hard drive still showed that the space was the same). I'm not sure if I imported some problem from my iBook or if my hard drive was just messing up again, but I've decided that I either need to upgrade or get a new computer.
Basically, I am thinking about upgrading my memory, getting a new hard drive, and upgrading to leopard (mostly for time machine). Or, possibly getting a new iMac or waiting a bit and then getting a new iMac or even (gasp) a PC (highly unlikely).
I was going to get the memory from ramjet and I was thinking of only adding 1GB to make 2GB but could be persuaded of getting more but 400Mhz DDR memory is a bit more expensive than other types. As for the hard drive, I was thinking about getting a Seagate Barracuda 7200.10 SATA 3.0Gb/s 320-GB Hard Drive with a 16 MB cache. I could pay $15 more for a 500GB with 32 MB cache but i really don't need the space and am unsure whether the cache will really help much. Seagates used to have a pretty good rep I thought, but now they seem to be getting mixed reviews, so I don't know.
Obviously, I am no computer expert, so any help would be great. Would it be worth it to spend between $250 and $325 to get the memory, drive, and leapord when I could maybe sell my G5 and my 23" apple cinema display (the old clear kind) and get an iMac? I could maybe get about $700 - $800 for the G5 and around $300 - $350 for the display. Will an iMac be faster than my G5 with the upgrades? I don't think I need a mac pro for my current uses.
Thanks for your help. Feel free to offer advice on what to do with my iBook too.

Memory: $60 for 2 x 1GB, I'd call that very affordable.
http://eshop.macsales.com/item/Other%20World%20Computing/3200DDR2GBP/
Disk drives: 2 x $69 for pair of WD Caviar 640GB
http://eshop.macsales.com/item/Western%20Digital/WD6400AAKS/
It is not about capacity as much as speed and quiet, cool, and how well it handles OS X. I use half the drive, other half is unformatted free space. I'd skip the Seagates. 7200.11 is current.
I expect new iMacs in '09 as they are overdue.
Hard drives you keep or put in FW case.
Current Leopard is 10.5.4 DVD but would be nice to see another DVD now with 10.5.6, $109 (Amazon, maybe less Newegg?).

Sounds like three things you may not be doing or have:
SuperDuper for backups. You don't need Leopard.
Disk Warrior. Everyone, or I should say "HFS+" needs #1 disk repair utility.
Backup drives. Two backup sets you switch between, and a small "emergency" partition on one for running Disk Warrior and such.
I replace or move older drives to backup use and put new boot drive in on a yearly basis. Some new drives and memory should be all you need. A couple people even stress their system with graphics and video, and upgrading to 3 or 4 new drives revived their system so that they could hold on and wait another year.

I want to run hardware test on my Power Mac G5 but it isn't working.

What I tried:
I have the original install disc 1 which came with the machine in the optical drive (which is the usual one). I printed the hardware test guide which is on the disc, disconnected everything but mouse, keyboard and monitor. I tried to boot, pressing the Alt/Option key, but the "system picker" or boot menu won't show up. What happens is what somebody described as for "old world" macs: my system boots with no finder window open and without the white screen and apple logo (which usually shows up during startup).
I also tried something I found in a user manual pdf for Power Mac G5 on the apple archives: Booting and press-holding C (btw it's strange that this manual says something different than the manual on the original disc). What happens here is that my machine is booting from the original disc but it boots in Installation mode. I looked at every drop-down-menu I could find there for several times but there is definitely no hardware test, since this is thought to install Mac OS 10.4.
I also tried the Intel-way and holding D during boot, but no surprise, it only booted the first drive (like it should on a pre-Intel).
But something about this all is very strange. Yesterday night I tried all these steps above and when I was close to fall asleep in front of my monitor it suddenly worked and I made it finally into the hardware test. If I remember correctly, I was holding down the C key, but as I said a was pretty dizzy and can be mistaken. I ran hardware test once enhanced and it stopped during ram, giving me an error code I wrote down. But since I made it into the test and was so tired, I thought "lets continue tomorrow" which was my epic fail for this year, I guess. Today I repeated every step, every way I tried but it just doesn't work; and I read sooo many forums and Q&A's.
By the way here is my error code which appeared after 49 minutes (to proof I didn't dream this):
"2MEM/1/4: DIMM3/J14"
Why do I want to do this?
Around the 1st of September this year my Power Mac G5 didn't boot anymore (the fan speeding issue). After reading a little online I came to the point that its either my Ram memory or its my graphics card or its Pram or NVram. I resetted Pram and NVram, I also replaced battery and then it booted again for one day but on the following day it didn't. I repeated every step but the battery replacement since it was a brand new one. It can only be Ram memory or my Graphics card (which is the standard one for this machine).
Since then my Power Mac was rarely in use, only two or three times in Firewire Target Mode to access some of the data. Yesterday I wanted to do this again; booting it in FT mode but I must have connected my keyboard too late during booting and my machine surprisingly booted just fine! I was so stoked about this! Then I wanted to find out why it didn't work for a while and started several steps. Ran maintanance scripts, repaired the system volume, checked for enough free space, checked my Ram and then I stumbled on the interwebs over the hardware test which is delivered on the original install disc 1 and I never heard about this before (strange enough). What followed is written above.
What do I have?

Sorry for the German but I think you still get it. The PPC was delivered with 10.4 and I bought it used from a friend with his original Update disc to 10.5 and I updated to the max, 10.5.8. I have 2x 1TB drive (similar ones) together as a Raid0 and three partitions on it. (I know now that it doesnt make that much of a sense).
Yeah so I really want to find out why my machine didn't work for three months but since it is so old and I'm a student, it doesn't make any sense to me to go to an Apple store or similar to have it expensively serviced since there is no guarantee that these guys really help you (heard some stories about the local stores here).
Is there a way to re-access the hardware test and run it to the end?
As you might have noticed, I'm pretty desperate. I would soooooooo appreciate it!!
Best,
Erik

Replace the memory in the DIMM 3 slot.
If you are running Mac OS X 10.5 you can use this program to test your G5's memory:
http://www.kelleycomputing.net/Rember/
It will subject your RAM to a more thorough test than Apple Hardware Test.

Please help me!! My Power Mac G5 is stuck at the grey apple logo screen and nothing is working!

My computer froze a few weeks ago and I got a grey screen that told me I needed to restart the computer. When I restarted, the computer froze on the grey screen with the apple logo. No pin wheel. Nothing. Eventually the fan begins running at warp speed. I've scoured this discussion board for a solution and I've read every possible thing I can find on the Internet regarding this issue. Nothing is helping. I've tried reseating memory, resetting PRAM, I replaced the PRAM battery, all the standard stuff on the message boards. I can't run a disk, i cant boot from a disk holding down c, but I can hold down the option key to open the hardware test, I've done the extended and short test and passed both.
When I hold the shift+command+v it tells me-
com.apple.driver.appleintelcpupowermanagement isn't a valid Mach-o (magic is cefaedfe)
Error mapping module file com.apple.driver.appleintelcpupowermanagement
Can't map com.apple.driver.appleintelcpupowermanagement in preparation for loading
Can't determine dependencies " "
Can't alloc class " " blah blah blah
I'm pretty sure this is some sort of kernel panic. This computer has been pretty much trouble free in the 8 years I've owned it. I had recently upgraded iLife to iLife 07 before the trouble happened.
I've also been able to get it to boot once or twice since then. I get a message that says" the computer was shut down blah blah do you want to send a report to apple?" I'm able to do some basic stuff like back up some pictures onto my external hard drive and then it will freeze again and the fan will come on. While I had access to the desktop I checked the disk repair permissions and they were all messed up. I tried repairing permissions but I don't think it worked. Also the time and date was messed up which made me think it was a battery thing. Lately I haven't been able to boot at all past the apple screen. I don't have much money but I have to get this fixed!
Some specs--

Just to be clear this is the power pc from around early 2005, not the intel based g5, not the water cooled one, and not a Mac Pro!

If I shut it down cleanly (Apple menu -> Shutdown), it shuts down, but then the power button does not work. After unplugging the computer and plugging it back in, the computer is able to power on successfully. I have reset the PRAM and have reseated the PSU connector.
I am using Mac OS X Tiger 10.4.11, but the same problem occurs under Mac OS X Leopard 10.5.8. I don't think the operating system really matters with this type of issue though, because the power button literally will not respond until I unplug and replug the computer.
Any suggestions?

Still not sure what Mac you have, but do you have a multimeter?
You can convert an ATX PSU for use on a G4...

Hank, have you tested the MDD PSU?

What are the normal operating temps for a G5 Quad Core Power Mac Tower?

I asked this within another thread but I am afraid it will get buried and think it deserves its own item.
I just downloaded Temperature Monitor and have been looking at the data. I have no idea how to interpret the figures and there are no listings of specified upper and lower limits even though there is an area where those numbers should go.
The numbers are constantly in flux, going up and down a degree or two but here is a recent example from a screenshot taken while I was running WORD (but not working on any document), Terminal, Apple Mail, Firefox (two windows open), Temperature Monitor, Preview, Dashboard and Finder:
Air Tunnel 99.5 degrees F
Air Tunnel Heatsink 92.8 degrees F
CPU A Core 1 Diode 107.5 degrees F
CPU A Core 2 Diode 107.8 degrees F
CPU B Core 1 Diode 108.0 degrees F
CPU B Core 2 Diode 111.5 degrees F
Drive Bay 87.8 degrees F
Graphics processor chip 131.0 degrees F
Main Logic Board Air Inlet --- (this is always missing)
Main Logic Board Backside 108.7 degrees F
Memory Controller Diode 133.9 degrees F
SMART Disk WDC WD2500JS-41M.... 104.0 degrees F.
The icon for the program, in the dock, gives me an ever changing number that is perhaps an overall reading - an average. Right now the number is 106.4 degrees F (taken some minutes after the screenshot providing the above data). Always in flux.
Do any of these temps look alarming? And HOW and WHERE do I find out what the temperatures SHOULD be?
PS I have APPLE RAM.

If you want to find out whether a sensor value is within normal limits, please select the menu item Window > Show Overview (or press Apple+1) and look for the limits in the third and fourth column of the sensor table. They contain the known official limits Apple has specified for readings acquired at the given sensor locations. If no limit is given in the table, this either means that it does not make sense to specify a limit for this particular sensor (e.g. the battery capacity should not have limits), or Apple hasn't published any specifications for this sensor.
Note that all up-to-date Macintosh models automatically shut down or enter sleep mode if one of the readings exceeds a critical limit. For this reason it is impossible that your computer can be damaged in an overtemperature condition.

Thanks BDAqua, it does sound like a bad capacitor. The PSU is one that I put in a few years back when Apple was giving them out so as to reduce the fan noise. I kept the old one until last week when I sent it off to be recycled. I suppose it would be a tough job to find the bad capacitor and I doubt that I would have the skill to replace it even if I could find it. It's not like I really need this power mac since I have a Mac Pro 1,1 but I do occasionally want to run something in OS 9 and I do love this machine for what ever reason. There was remarkably little dust inside but I went over it with a can of dust remover.
