I scanned the posts and didn't see this question, but honestly I didn't read all 20K + messages.I bought in late 2005 a dual 2.3 G5, about 6 months before the Mac/Windows combination came out. Does anyone know if I can upgrade or is it too costly to do so compared to buying a new machine.
Information:
PowerPC G5 Dual 2.3
Mac OS X (10.4.11)
is it even possible to upgrade an old dual core powermac g5 to a quad core or even an 8 core.
I have a dual core one and i really need to upgrade to a quad or even 8 but it is so expensive to buy a whole brand new one and i was wondering if there was a way to just get a new processor and more ram or what not.
I am looking for a tear down guide for my 4 core power mac. I need some instructions on how to remove the CPU's since I bought this for $100 and found the part for $250.

I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?

I left my iMac on overnight last night to finish downloading some stuff. I woke up and all our clocks are flashing, so we must've had a blackout. Anyway, I went to check the progress of my downloads, and the iMac was off. I pushed the power button and nothing happened. No fan noise, HDD noise, nothing. I've been trying for almost two hours now and nothing is working.

It seems I should not buy a quad because of leaking.
Are the dual core reliable?
I'm just going to order a new Mac Pro and noticed that it was slightly cheaper to order the base dual processor model and buy the 2.93GHz hex cores myself. A couple of questions arise:
Will my AppleCare still be valid or will I have to keep the 2.4GHz Xeons if I need to return it to Apple for any reason?
Is there market for the 2.4GHz processors?
Can I upgrade to the 3.33GHz processors or will this not work?
I am looking to get another mac to do some basic video editing and encoding. All the editing is going to be done in the mpeg4 format and once the video has been edited I am going to encode the video into H.264. My question is which will be better A Power Mac Dual 1.8Ghz G5 or a Mac Mini Core 2 Duo?
I am looking for stable set up that can handle encoding video for a few hours at a time. I am leaning towards the Power Mac Dual G5 because of how much more cooling it has however that said a Mac Mini with a Core 2 Duo running at 1.66 Ghz would also probabley work well.
Has anyone tried to upgrade their old iMac G5 with a new Intel core Duo processor? If so how do I go about installing one?

why i have to unplug the power cable from the back of my imac after every power failure at my home to get the imac to boot up. I've tried resetting the surge protecter and unplugging there. However, the only option is to unplug the cord from the back of the monitor/imac before it will boot up.

I do alot of photography with a canon dslr, I also plan to edit short HD videos as well as some photoshop and flash animation work.
Will I benefit greatly from the Quad Core Imac over the Dual Core Imac?
I have an opportunity to get a single 3.0 GHz quad core Clovertown.
Should I go for it? There's no advantage to having two cores in two sockets versus having four cores in one socket, right?

Just in case Apple surprise us with a Sandybridge Quad core, and even if they don't I was wondering the following.
1 ) During sustained use in 3D gaming does a Quadcore with lower clock speeds beat a dual core with higher clock speeds.
2) Can the quoted turbo speeds be achieved in sustained use (ie 3D gaming where maximal load can be applied for a couple of hours).

While installing windows 7 via bootcamp tonight, I suffered a power failure a minute or two into installation. Upon reboot, I have only a black screen with flashing curse. I have attempted to reboot in safe mode, recovery mode and diagnostic mode, but I think the machine is not recognizing the keyboard.

So I was talking to my friend about the new MPs and that they should have two 6 core processors in it.
I plan on getting one for rendering scenes with Maya and doing stuff on AE, FCP, and the CS5 master collection. We were talking about his computer, which is one quad core processor.
He was saying that render times on Maya wouldn't be very different when comparing a quad core versus two hexa cores. I don't agree with him but would like someone elses opinion on this.
I currently have a 24" iMac with a 2.8 Ghz Dual Core but I'm looking at buying a Mac Pro.I have been looking at the 2.26 Ghz Dual Quad, will this be faster than the iMac? I'm not really all that hot on clock speed vs cores, could someone with the relevant knowledge inform me which is better?
View 7 Replies View RelatedUsing my iMac today working away and all of a sudden the screen went black, there was no power to the computer at all. I have checked the fuse and that is ok. I am getting power to everything else. I reset the SMC as per Apple instructions on their website. Again nothing.
I then left it turned off for a good 5 mins and then turned on the power. The fans turned on and the mac then chimed, the creen came on and I thought everything was ok. Then the computer turned off, fans and hard drive sped It didnt even start booting to the Apple logo or the log on screen.
I am thinking this is a power issue within the computer and this will need to be replaced. I was wondering if anyone else has had this problem. My iMac is a 2008 21inch iMac. It is connected to a APC UPS which again all power ports are working, as I have tested that with a desk lamp. What I do normally is turn the UPS when I have shutdown my Mac in the evening and then power it up next day. While the UPS is doing is power self test I then boot the Mac, I am wondering if I should just leave the UPS turned on all the time and just unplug my iMac when I am not using it. Sometimes I do pop it to sleep last thing at night, but recently I just turn it off.
It has had heavy use so I am wondering if it is indeed curtains and I need to buy a new iMac. Maybe it is an excuse to buy a 27inch one! (Would be nice)

a friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?

I shut it down using the shut off button and unplugging it from power for more than 5 munites.
I turned it back on, it does the usual startup chime and then gray screen. I have restarted twice from the shot off button and still getting the same result.

My imac does not turn on, not even make the noise when booting up. The only sign of life is the blinking light that tells you is on.
