IMac :: Base I3 27 Inch Or A Refurbished I5 Quad Core 27 Inch

Jul 29, 2010

Hello everyone, I'm currently looking to buy a 27 inch imac and can't decide whether to get a base i3 27 inch or a refurbished i5 quad core 27 inch. With the i3 I can get the student discount and qualify for the ipod, but the i5 is 23% off right now. Which should I get? Also is there a benefit of getting a 5 series graphics card over a 4 series graphics card?

Mac Pro :: 3.2GHz Quad Core Versus 3.33GHz 6 Core?

Aug 10, 2010

I'm one of the many many people who are juggling mac pro options in my head.

is the 3.33GHz Westmere worth the extra 640? Probably not, but now much faster will be it? 20%....30%?

I think I'm set on either of these two options, mainly using FCP and photoshop and a bit of motion. maybe a bit of gaming

Also I can max out them four RAM slots and get a 5870 with the extra cash.

Jul 29, 2010

I am trying to decide which of these two 27 inch imacs I should buy:

27 inch 3.06 core 2 duo model

27 inch 3.2 I3 model

Is the 27 inch 3.2 ghz I3 model a better value in terms of increased computer and graphics performance and is it better to get the 2nd generation model because of prior issues (i.e. yellow tinge)?

IMac :: 27 Inch Quad Core I7 HD 4850 Temperature?

Nov 18, 2009

I just wanted to share what's been going on with my i7 which I received last Friday. Immediately I was curious about what sort of temps I was going to be running so I installed Temperature Monitor. At idle my graphics readings hover around 40C. However, when playing Warcraft 3 my Graphics Processor Temperature Diode reaches up to 84C.

I don't really know what temps are acceptable, I was just wondering what other i7 HD4850s out there are running. To deal with this seemingly high temperature I installed smcFanControl and boosted all fan speeds by 50%. Noise doesn't seem to be proportional to fan speed at these levels so no probs there. Now I run at 64C at load and I am at peace with that.

Shouldn't the OS be increasing fan speed on its own?

Would like to know what you guys think and observe in your i7 machines

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.

IMac :: Have An Inch Wide White Stripe On My Screen?

Jun 11, 2008

I have an inch wide white stripe that runs from the top to the bottom of my screen. This is on an Imac. The cursor disappears when going through it but pops out on the other side. It doesn't move but I can drag my window back and forth to view the part the stripe covers.

Any ideas or should I locate a local mac repair person?

Software :: Apple MacBook 13.3-inch 2GHz Does Not Continue To Boot Up.

Apr 5, 2009

My friend has an Apple MacBook 13.3-inch 2GHz (model number: A1181). When I boot up the computer, the screen is gray and does not proceed to show the Apple logo. The MacBook continues to show the gray screen for quite a while. What can I do to identify some of the problems with this computer? The one caveat: I am in La Habana, Cuba and there is no concept of an Apple Store or Mac support.

IMac :: Which One Is Better/an 3.06 GHz Intel Core 2 Duo Or An 2.8 GHz Intel Quad Core?

Dec 18, 2009

first, I didn�t know if this thread should be here or in Buying Tips, but anyway. My doubt is about the brand new 27� iMac�s processor, If I should buy a more GHz one, but with only two cores, or should I buy little bit less GHz one, but with four cores.

It really worth pay $200 more? It really worth the four cores? My main needs are run CS4, some Final Cut, maybe Logic Studio, and switch between different OS's (OS X, Windows, and Linux). I think even a 21.5� model would be more than enough, but I just wonder If Quad Core gonna give me more power (I hope so).

MacBook Pro :: 13 Inch Core Temp - Is It Dangerous

Apr 11, 2010

My question is this, is it normal for core temps to sit as high as 90 - 100�C while doing things like rendering video and gaming. For example, I was playing the Sims 3 for the first time the other day, and the core temps sat at about 95�C while playing. Is this a normal temperature? or is it something I need to be worried about.

I've already downloaded SMCfancontroller and use it whenever I'm doing something like encoding a DVD. I'm just overly concerned that I might cause some damage if I let it get around 100�C too often.

IMac :: The New 27-inch IMac Uses Up To 365W Versus 280W For The Old 24-inch!

Oct 20, 2009

The new 27-inch iMac uses up to 365W vs 280W for the old 24-inch! (going by Apple's published max. power consumption numbers. I doubt they would lie because it isn't exactly favourable for them to put in falsely high numbers in an environmental report).

That means there's some extra beef behind the extra components. Perhaps the ATI 4670 is a bit overclocked and the 4850 runs a bit faster than the old iMacs? Admittedly that 2.8 GHz i7 is going to suck a fair bit of power - the recent 2.8 GHz i7 860 model runs at a 95W TDP, however, the quad core iMac isn't available until November. So it won't be using the i7 860, and my guess it is using another custom processor, something a bit more power efficient, somewhere in between the 55W TDP of the old iMacs and the 95W TDP of the i7 860.

The difference between the power consumption of the two computers is 85W. The old iMac had a 24-watt digital amplifier, this new one has two 17-watt amplifiers. That brings the delta down to 75W. Say the iMac's i7 processor has an 80W TDP. That now brings the delta down to 50W. The new display likely wouldn't increase power consumption because of the LED backlight.

I'm not sure if I'm missing much (OK, two extra RAM chips may use another few watts), but there is still a fairly massive 50W unaccounted for.

Just a bit of fat to chew on

Software :: New 24 Inch Intel IMac Won't Start?

Jun 22, 2009

I just got the new 24 inch intel iMac yesterday and it was working fine until tonight. I installed Skype and as I was using it, the computer froze and said I had to restart. So I did that. It happened again, but this time, it wouldn't restart. It went grey and kept making loud beeping noises. I looked up what could cause this and it said that if the RAM was upgraded improperly this could occur. The problem is, I never upgraded the RAM. Its been working fine for the past day until now. What should I do?

IMac (Intel) :: 27 Inch - Screen Randomly Goes Off?

Jun 2, 2014

I have a 27" iMac. Just recently, the screen has begun to randomly shut off. I then have to squeeze the power button, followed by a click of the mouse. This will bring me back to my password screen. Sometimes, that would be it, other times, it will do it repeatedly, for no reason, and then settle down. 

Just for those of you who are bound to ask me about my Energy saving settings: Computer to sleep – Never. Display to sleep – 15 min. 

It seems to me that this could be a hardware issue, but just incase any of you have had any experience of something similar, I thought I would ask.
