PowerPC :: Replace Tower G5 Single Core Chip To Dual One?

Jun 23, 2009

Someone I know wants to buy a used Mac pro G5. It has a speed of 1,8 Ghz. I think he's going to use it for music. (logic pro, adium). But he said he was going to use FCS as well. His question was if he could replace the G5 singlecore chip, with a G5 dualcore chip. And if that's possible, could somebody give me extra info about compatibility and such. For example, will it just boot without problems when you replaced it, or do you need to do extra things (drivers, reinstalling the os and such). The G5 will be used in the near future for HD video editing. Also, I know the new intel mac pro have graphic cards from nvidia and ati. But what graphic cards do the G5 towers have? are they good?

PowerPC :: 20" IMac G5 (1.8ghz Single Core) - Not Booting From DVD?

Jan 18, 2010

I have put a brand new hard drive in the machine. I took off the plastic bezel to the power cord, to make sure it's plugging in all the way. I turned the computer on while watching the LED's on the logic board. All 3 stayed on, and the 4th never came on.

I have unplugged it, left it unplugged for a few minutes, plugged the cord back in while holding the power, then turned it on (forgot what that was supposed to accomplish). No change.

I have reset the PVRAM (or whatever) 3 times in a row by holding command-option-p-r until I heard 3 chimes after the initial boot. No change.

I can get into open firmware, but have no idea what I could even try in there (other than ejecting the DVD).

I hold down "C" while booting, it chimes, it goes to a blank grey background, then proceeds on to the white screen with the apple. It sits there for a few seconds, then starts spinning the circle for a while, then shuts down. I hear the optical drive spin up, but it does nothing.

Mac Pro :: One Quad Core Chip Versus 2 Dual Core Chips?

Mar 6, 2008

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?

IMac :: Is There A Way To Chip Off CPU Usage From Other Programs That The Computer May Be Using

May 20, 2009

I purchased my first Mac ever, the iMac with 3.06ghz, 8GB and 1T.


Now, I got this iMac to use Protools with plugins. Now I'm only using 3 tracks with virtual instruments and is already asking me to increase CPU usage or remove RTAS(virtual instruments).

Is there a way to chip off CPU usage from other programs that the computer may be using? Anyone has solution except removing some virtual instruments, I mean I got this iMac to work with music.

IMac :: Is The Quad Core I7 Faster Than The 2008 Octo-Core Mac Pro?

Oct 22, 2009

So the older Mac Pro's from 2008 have 2 2.8ghz Quad Core Intel Xeon processors, without hyperthreading, for a total of 8 cores, and the top of the line iMac has a Quar Core i7 2,8ghz with hyperthreading for a total of 8 (virtual) cores.

With the ghz being the same but less "real" cores, but probably newer CPU architecture, which CPU will actually be faster?

Sep 30, 2006

currently i have a blackbook and imac core duo, 17 ". My macbook beats the imac in everything except graphics. Before i got my imac i seriously considered a g5 dual 2.0, but the money wasnt there.

How much of a performance increase will i see IN APERTURE going to the PM, if any? i would need a good increase to justify it, and eve then im not sure my parents would be ok with me spending a few hundred bucks to upgrade

IMac :: 27" Imac Quad Core-i7 Good For Gaming?

Jan 7, 2010

I'm in desperate need for a new computer, for Gaming/school work.

I Am very interested in the New 27" Imac quad core-i7...but I'm scared.

I have read threads upon threads about the screen flickering/yellow glow and such and my question to you all is, when to buy my new imac?

I want to buy it without these problems of course.

Does anyone know when Apple will be fixing all these problems? (If they havint already)

IMac :: Quad Core I5 OR Base Model Core I3?

Jul 28, 2010

I know other threads exist, but they don't have responses specific to me so what's the harm in one more?

So, I am going to be selling my late 2008 15" MacBook Pro this week to get a new 27" iMac and I just need some legitimate advice from those "in the know" on processors.

I plan on having this iMac for about 3 years to do the following tasks:

1.) Record and edit HD cable (1080i) from an Elgato EyeTV HD - will include some encoding of 2+ hour sports game recordings

2.) Some light editing of 720p iPhone 4 clips in iMovie

3.) Surf the web, iTunes, iPhoto, Mail, and all the other standard stuff

Assuming budget is an issue, would you recommend me spending the extra money for a Quad Core i5 iMac or would I be ok based on the info above just going with the base Dual Core i3 model?

Like, will there be a considerable difference in the two machines (factoring in processor and graphics card) that will really be worth the extra $300 - $400 for 3 years of use?

IMac :: Weird Boot Issues On IMac Core Duo?

Oct 28, 2009

Back in August, I did an OS update on my iMac, and the machine wouldn't reboot. I was able to reinstall Leopard by booting from a disk, and all was well for a few more weeks. The machine seemed to run normal, with the exception of 5-minute-plus boot up times. But within a few weeks it stopped booting. I installed Leopard on an external HDD and figured I'd leave the internal alone until Snow Leopard came out.

A few weeks later when SL was released, I booted from the install disk, found the internal HDD, and went through the installation process. Everything went fine but the machine would not boot. I installed SL on my external HDD running Leopard, and everything was fine. I've since been running my computer off the external.

The internal HDD no longer shows up on the desktop, in Disk Utility, etc. I'm fearing it may have died. More worrisome, though, is my machine doesn't always boot up, whether from my external HDD (set as the startup disk) or from CD. By "doesn't always boot up," I mean most of the time when I restart, it just sits on a gray screen, nothing happens (even when holding "Option" or C.) Sometimes it will boot, but takes 20 or 30 minutes to do so.

I'm considering replacing the internal HDD, but am curious, does that seem like the issue, or might the failure to boot from externals and CDs indicate a more serious problem?

The first Core i7 and Core i5 benchmarks are available. Quite amazing to see how much faster the Core i7 is even compared to the Core i5. (via digg) I'll definitely go for the Core i7 now that I've seen these results.

IMac :: Chip In Glass Behind Screen - What If They Only Replace The Glass But Get Dust?

Aug 11, 2010

there is a small chip behind the glass of my 27" imac. It's about the size of a small crumb or the eye of a small needle. It's hard to see, but it's definitely there. Today is my last day to get the imac replaced or repaired. I have a feeling if I bring it in that they will see there's no reason to swap out the entire imac, and if there is I would have to wait awhile because it's a custom high end one so they don't have the specsI'm worried if they swap the glass that it's just some 19 year old kid that does it and he won't be careful with the screen and will get dust, finger prints, etc. on the glass making it worse.

OS X :: Single User Mode With A New IMac?

Nov 23, 2010

I just purchased a new 27" iMac last week and can't get the new Bluetooth keyboard (that came with it) to boot in Single-User Mode.

I know if it were older and used a dongle it wouldn't do SUM (since it wouldn't load until later in the startup process), but I was told this new system would do SUM without having to get my cabled keyboard out every time I want to do SUM or a Safe Boot.

Mac :: Imac 27 With Core To Duo And I5?

Nov 17, 2009

I planning to buy a new imac, and i cant make my mind up. here the 27 core 2 duo cost 1580 euro and the i5 cost 1880 euro. money is not really an issue but on the other hand why spend the extra money if I don't need it. In your opinion who should by the i5?I am using mostly photoshop, dreamweaver, imovie, browsing with multiple tabs open at once and also I will be using a software (not sure which one yet) to put my VHS videos on dvd with some editing. I know the core2duo will do just fine but will you see a significant difference with the i5? is there anyone that has bought the i5 who previously owned the 24 3.06 core 2 duo that can tell me his impressions?

MacBook :: Core Duo Max RAM / Install Single 2gb Stick Into Working Slot?

I have a 2006 Macbook with a "Core Duo" processor. When I got it, one of the RAM slots was busted, so I put a 1gb stick in the working one to add a little speed. My question is, since the maximum RAM in this model macbook is 2gb, would it be possible to install a single 2gb stick into the working slot?
