PowerPC :: Graphics Distorted On G5 Quad?
Nov 23, 2010
Well I was swapping some processors around on my G5 when I noticed that I was getting some weird graphical glitches. They went away when I disabled the 3-4 CPUs and made it a dual-core. The glitches are replicable when sizing windows and consistent when different window sizes. I'm starting to wonder if one of my CPUs are faulty...? Everything seems to be running fine otherwise. I attached a pic of the graphic anomaly I'm getting with all 4 core active and it only appears around text and it's always red color.
On a side note I also noticed that 2 of my dimm slots are reporting errors, the two outer banks. I've removed them and it's fine. Gonna load up the diagnostic discs to see if it finds anything.

I need a new/best card for a G5 quad 2.5. I know it's old (4 years) but it's still used quite a bit - mainly for Photoshop work. The card needs to run 2 x 23" Cinema Displays. I'm not sure if it makes any difference but it has 16GB memory (twice as much as our new 2.93 Quad can take - there's something not quite right there...)

After the 10.5.1 software I'm having a problem with distorted (stripes etc.) icons and menu dropdowns. Apparently not on my desktop or programs like Safari, Mail etc., only on icons and menu dropdowns, which I find odd. Sometimes it's gone, but after some time it reappears again. Anyway, sometimes my Mac (iMac G5, PowerMac12,1, 1.9 GHz) is going bonkers completely, which results in a first pink, then black screen. A hard shut down is then the only option. However, I guess it's videocard related (ATI Radeon X600 Pro). I did all the tests, fixes you can think of, but without any results. I contacted Apple support, but because this is an iMac, you can't just replace the card, they told me that the whole motherboard should be replaced, which will cost me approx. 700 EURO. Of course I am not willing to do that, which means that I'll have to buy a new Mac. Of course a new Mac is always a delight, but I find replacement after just 2 years unacceptable.
Information:
iMac G5 PowerMac12,1
Mac OS X (10.5.1)

I bought my 15" MBP in late June of 2007. Recently I've noticed that the computer has been running extremely hot, even when just playing a simple youtube video or anything else flash related.The other day I was playing the Sims 2 in Windows through Bootcamp and the graphics became distorted and garbled. I had to hold down the power button until the computer shut off because it was impossible to see or do anything. This has happened a few other times while paying the game.I have had some waking issues where the screen will not come back on after the mac has been asleep. The only way to fix this is to hold down the power button and wait for it to fully turn off, then reboot.

When upgrading my G5 I simply backed up the old drive to the neww 500 gig drive in bay 2 and then switched them. Could I just switch it to a Quad and the voila! it works? Could it be that simple or will I need to reinstall all the software?
What about installing the drive into a Macpro? Could I just place it in a bay and then run all my programs, like Photoshop, Imageprint, and Office?

I just purchased a Quad G5, from the original owner. Original owner, stated, that the machine was in excellent condition, and had not had any problems, nor parts replaced under Apple Care Warranty. Twice today, I had programs crash. 1st crash involved Photoshop CS3 Ext. 2nd Crash, involved FireFox & Photo Mechanic, which then I received a message from within OS X, to restart my tower.
I am quite surprised about the crashes, and do not know what to do, nor expect. Before, I received the G5, the HDD was wiped, with a fresh install of 10.5.6...
I'm also having a Bus Power issue. Before the G5, I had an aluminum keyboard, plugged into my iMac C2D, and I had no problem with Bus power, driving either my Thumb Drive or HDD, but with the Keyboard, hooked to the G5, I'm getting insufficient power warnings
Also, my 23" ACD will not go to sleep. I've got the screen saver set to 3 mins, which does come up, and the time set to 10 mins, for the display to go to sleep. However, when it hits the 10 min threshold, the screen blinks off for a second, then reverts to the active desktop, and the cycle begins again.
Also, with the 23" ACD, I'm seeing, what appears to be a ghosting effect, when I have apps layered on top of each other. It has been occurring with various apps, such as having Photo Mechanic on bottom, then Firefox on top, then Photoshop on top of it.

Well I'm kinda basically overhauling my G5 LCS so I figured, why not lets try and put a heatsink from my 1.8ghz G5 onto the quad G5 CPU since I have it out. I only have one CPU in it right now and it's actually doing pretty damn good. I set the Energy prefs to Reduced as a precaution.
If I ditch the LCS and make this a permanent setup, I will have to machine some custom brackets to hold the heatsinks to the logicboard/case. I have the G5 laid on it's side at the moment since there is no way to fasten the 1.8ghz heatsink down.
Below is a screenshot of the temps
This is with a constant 50% load on the CPUs as I just have it folding right now.

I have had this quad g5 (dualcore 2.5ghz X 2) laying around for about a year that I purchased for $100 without a hard drive, super drive or a power cord. I was told that it was non working in the manner that ONE of the dual core cpu's had gone bad. I will be receiving my power cord this week to make sure that it still powers on but what the problem is.
My question is: If only one of the cpu's are bad, what is the part number I will be looking at? I am not wanting to spend a fortune on this to fix it, but If I do get it working I would like to drop 8-16gb ram in it, and setup a raid with 2 raptors.

My PM G5 Quad is in need of a new logic board and processor. I am waiting until after WWDC to see if there will be an update to the Mac Pro line - as I will be buying a new one to replace my old one. What's useful to keep from my old G5? I feel like I'm parting out an old Camaro or something. I'm planning to at minimum keep the HD and just pop it into the new machine (hope I can do that). I'm fairly certain the RAM is not going to be compatible, but I'm wondering if there's anything else I can scavenge off the old machine.

I am using a G5 Quad processor with a GeForce 6600 graphics card. I am working on a project in Second Life [URL] and have been advised that I need to update the driver on my graphics card to solve some problems encountered in Second Life. There does not seem to be an update for this card for Macs. I have asked Apple for help, but they have told me my serial number does not exist even though it is registered and I have had technical help from them in the past. Second Life say they do not support this graphics card!

I have always been interested in getting a G5, ever since they came out. I might be able to nag a Quad G5 for very cheap, but I have a question. I know that an Intel Core 2 Duo is faster than a G5, but how is it faster than the Quad? What exactly makes the Intel faster than the G5? I am looking at the Apple specs of the Quad and to me, it looks like a really solid computer, especially for 2005.
2 Dual Core 2.5GHz PowerPC Processors
1MB Cache Per Core (4MB Total)
FSB 1.25GHz Per Proc
Up to 16GB DDR2 PC2-4200
So, what makes the G5 Quad, or even Dual Core/Dual Proc G5's so weak?

Is there anyway to fix this other than buying a new graphics card? I've searched but couldn't find a solution. The 7800GT in my G5 always spins at top speed and is so much louder than the whole system. I've had it disconnected for a while but I don't want it burning up . Thinking I just might wire it to the 5v side of the molex connector on the optical drive?

What is going on? For no apparent reason, this computer decided to start making random "booping" sounds this evening. There is no error, it's not the mail, it even does it when I have my external speakers turned off. Anyone else have this going on? This is the first time it has happened and it's been going on all evening.

I want to buy this item:
http://www.sweetwater.com/store/detail/G5Wireless/
The bluetooth/airport extreme card for my PCI-e Dualcore 2.0ghz G5. I'm happy to install it myself. However I am leaving to go back to the UK on jan 31st, and sweetwater don't actually stock the item, and it will take a while to get it to me unless they expedite it from Apple and charge an extra $42 or so, which is too much for me. Anyone know who might actually stock the item and be able to send it out quickly?

I've been having problems with the optical drive on my G5 Quad for the last few months. It makes a clanking noise every few minutes, similar to the sound it makes when you put in a cd. Also, every now and then when I put in a cd it just doesn't read it, and it makes itunes crash. The drive is an LG HL-DT-ST DVD-RW GWA-4165B. I have read lots of bad things about this drive on the internet, and it also happens to be much slower at importing dvds than the pioneer drives that are (or were) also shipping with some G5s.
I finally went down to my apple store, in The Netherlands. I explained the problem to the tech guy, and he said they would replace it under warranty. However, when I asked if it was possible to get a pioneer drive, he said they had no control over which brand they receive on replacement parts, but that almost always they get pioneers. Well, I took it in and they replaced the drive. They refused to do a test on it though, arguing that they were fixing another G5 and wouldn't be able to hear the noises I was complaining about (there was also a strange noise coming form one of the fans). The guy suggested that I brought it back some other time, and said he was absolutely sure he wouldn't find anything (turns out these guys also happen to be clairvoyants, or so they seem to think!) Coming from America I find it really hard to believe how rude and stupid the apple people can be at this store in The Hague, but unfortunately I can't avoid having to deal with them while I live here (there are endless horror stories about this particular shop). I don't have a car, so I had to take a cab there and back, which ran to about � 20, plus all the trouble and the wasted time. But sure, why not just bring it again some other time like the guy said?............

I posted this on the buyers guide forum but got no response. Maybe you guys can help.
I have a G5 dual 2.0 with 5.5 GB ram and an ATI Radeon 9600 pro graphics card.
I have been running Final Cut Studio with no problems. Once I upgraded to FCS 2, it seems to drag with some of the new fetures. Motion 3 seems really slow! So I added 2 more gigs of ram to bring it up to the 5.5.
I am waiting for the new MP like so many of you, but I will keep this computer for off line editing and compressor and for a part time assistant editor to use.
Would it be worth it for me to upgrade the graphics card?
If so what would be a good choice of card for this type of work.
FYI the last computer game I played was Zork, so I don't care about gaming.

I had recently purchased a 2nd hand G5 PowerMac with dual 1.8GHz processors and PCI-X slots. I think it was released in November 2003. It's a great machine, but suffers from its lacklustre 64MB graphics card. My Mac man told me not to bother, but I would like to investigate the option further. What do you think is available and where would I obtain one of these things? Oh, I should also ask the most important question...is it worth it?

Really wanted to update my Powermac this year to a MacPro but as I'm getting married it's going to be an expensive year so I've decided to upgrade the G5 2.0 DP I already have.At the moment the kit I have is pretty good in that I have 1.5 gig of memory and 250gig of hard drive space but I'm open to suggestions.The G5 I have is the PCI version so I'm a bit limited as to what I can upgrade but the main area I'm looking at is with the graphics card. I had BTO the ATI 9650 256meg card but I'm looking for something better. I've just started to get into "World Of Warcraft" and would like the best graphics card that is value for money.

I brought my iBook G4 to school today, and it sent the whole time in my backpack. When I got home, I turned it on, and it started booting up, but when the screen came on, it was only gray. I opened it, and saw that the lcd was still plugged in, so what could this be? Can the 32mb vram iBooks get the graphics problem?

Why is it that an Imac G5 doesn't perform nearly as well as even the Core duos in terms of FPS?Why is it that the PPC artictechture seems to not be able to run games as well, even with a comparably speced graphics card?I can't really seem to formulate my question:Let's pretend we have two computers that are exactly the same speed. (Yes I know Intel macs are way faster than PPC)WHY oh why would the PPC computer do terribly compared to the Intel?

My hard drive on my old B&W finally crashed the other day. I got a new hard drive for it a few days ago. I upgraded the graphics card from a rage 128 to a radeon 7000 sometime ago. Do I need to put the old rage 128 in when I reinstall OS 10.3? Or is it ok to install it with the Radeon 7000 in it?

I'm looking on cragslist right now for an older powermac to use as a media hub and I think I found one. It appears to be an AGP G4 PowerMac (500Mhz-ish). I have a 256MB graphics card I was using with my PC, I was wondering if I could plop it in and it would work? I know it's probably a pipe dream, but it doesn't hurt to ask

All this talk of 8800GT's on the Mac Pros is putting me in the mood for upgrading the 64mb ATI 9600 in my stock PM g5 dual 2 GHz.I have an old Formac Oxygen ADC monitor (used as one screen of my dual head system) but the ADC connector on the graphics card seems to be dead, and everytime I plug the monitor in to the port, the Mac just keeps 'tripping' out and won't power up - almost like something is shorting out.As a result, I'm stuck to using just the DVI port (1 screen is so limiting after being used to 2!!), connected to an ancient VGA monitor. I really miss having a dual screen set-up, and this is another reason why I would like to upgrade the card. would be good to still be able to use my ADC monitor, but I guess only the older, low spec cards had these, and I'm probably gonna have to ditch the monitor and get a couple of DVI screens.
