Intel Mac :: Can The Processor In The 2009 Be Upgraded

May 17, 2012

Before I tear apart my iMac, it may just be faster to ask.  I am considering simply upgrading the processor on my 2009 iMac instead of purchasing a newer model.  Of coure the newer models could potentially have a different motherboard, mostly to support the Thunderbolt but if the differences between new and my 2009 model are not so significant, then a CPU upgrade may be more intelligent. 

My current specs are as follows: Model Name:          iMac  Model Identifier:          iMac11,1  Processor Name:          Intel Core i7  Processor Speed:          2.8 GHz  Number Of Processors:          1  Total Number Of Cores:          4  L2 Cache (per core):          256 KB  L3 Cache:          8 MB  Memory:          8 GB  Processor Interconnect Speed:          4.8 GT/s  Boot ROM Version:          IM111.0034.B02  SMC Version (system):          1.54f36 Question is, without looking, is this a "socketed" model where I can simply plug a new chip in?  Of course I can open my system up and see, but that will include "down time" and I prefer to avoid as much as possible. Just as with most "Winblows" systems and MBs, the chips are socketed and can easily be replaced where the MBs are compatible.  Mac can't be all that much harder, but I can't say I have ever seen a MAC CPU upgrade for sale.

OS X :: What's Chewing Up Processor?

Apr 14, 2009

About once a week, my computers gets bogged down hard. When I look in Activity Monitor, the CPU Usage graph is hitting the ceiling, but a quick glance at the CPU column in the process table above shows it should only be using about 30%. My guess would be iAntiVirus is scanning in the background, but according to Activity Monitor, it's using less that 1% of the CPU. Does the process table in Activity Monitor not really show all the processes? How can I figure out what is chewing up the CPU?

Mac Pro :: One Processor Or Two For Photoshop?

Feb 24, 2010

I currently use a G5 PowerPC 2.5 Quad with 8Gb RAM. With the ever increasing size of digital images (my camera now takes 24Mp images), I find the initial browsing of my images increasingly slow. Also, non-Intel processors are becoming less supported by the latest software and I figured it's time to invest in a new setup. Just today, I sent back my iMac i7 (as a result of the well publicised screen issues) that was potentially to replace my G5. I have taken the decision to invest in a new Mac Pro and utilise my existing 30" cinema screen. The likelihood is that I will wait to see what the 2010 Pro shapes up like, but in preparation, can someone please tell me what is better for photoshop (I will be upgrading to CS5 once released), one big or two smaller processors?? For example, looking at the current offerings, which would give faster/better performance, a 2.93 quad core, or 2 x 2.26 quad cores, each with 8Gb RAM?

Mac Pro :: Which Processor Is Better / Faster

Aug 12, 2010

I'm definitely no computer expert, but with all these Mac Pros with all these cores, I'm not sure how to read their configurations. The single quad core is 2.8 GHz. But if you get an 8 core, you get 2.4GHz. And then there's the six core which is 3.33 GHz!! Which of those is faster and why? I don't want to spend $1000 more for more cores if it's actually a slower processor

Mac Pro :: Processor Upgrade (E 0 Steppings)

Sep 21, 2010

I have an early '08 Mac Pro that came with one E5462 2.8GHz Xeon processor. I would like to upgrade the processors as much as possible. As far as I can tell from my own research as well as the information on other threads in the forum, the best processors I can put in the machine are the Xeon X5482 3.2GHz chips. I found a pair of them on eBay, but the seller says the steppings are "E 0 steppings". The seller describes the chips as "Intel Xeon Quad Core X5482 E S"... which sounds like they were Engineering Samples... I'm okay with that, but what about the "E 0" steppings? Will they work in the Mac Pro?

MacBook Air :: Why No I3 Processor In System

Why do you think Apple did not use the I3 processor in the new Air? Cost? I think it uses less power and is faster the much older Core 2 duo. I have not been able to find any information on it.

OS X :: KRB5KDC Uses 100% Of My Processor All The Time

Nov 12, 2010

I have a process on my iMac (core i7 quad, 16 GB Ram) thats called KRB5KDC. It uses 100 % of my processor, and 2,8GB Ram, All the time - Even just after i booted up. This makes the computer pretty useless as you can imagine.

After googling and mRoogling around i found out that the process belongs to Kerberos - some sort of network authentication protocol - i dont know anything about that, but it shouldnt use 100 % processor power.

Any help would be greatly appreciated, since applecare couldnt do anything but offer a hardware repair - strange solution for a software problem...

MacBook Pro :: Slower Processor - More Ram?

Dec 12, 2010

I'm in the market for a new MBP and, looking through the models, it's between the: 13" 2.4 GHz Core 2 Duo with 8gb of RAM 13" 2.66 GHz Core 2 Duo with 4gb of RAM I'll be using it for: Adobe apps (Flash, Photoshop, Dreamweaver, InDesign; often 2 of these at a time), videos (esp. streamed online), word processing, and general web browsing. I often have at least 1 of the mentioned Adobe applications, as well as a streaming video and 5-10 browser tabs open at once. So, which is better for my purposes, the 4gb more RAM but slower processor, or the faster processor with 4gb less RAM?

OS X :: Processor Performance Utility For 10.4

Anyone know if there exists a utility for 10.4 which replicates the "System Prefs.. Energy Saver.. Options.. Processor Performance" option but in a more accessible way? I tend to switch modes fairly often, so ideally I'd like a little menubar icon which I could click to toggle performance modes, or maybe a dock icon. No widgets please

Can it be done? Is there a second socket on the uni-processor Mac Pro model which will allow for the addition of a second processor to the board, to give a dual-processor machine? For instance, with the 3.33GHz Mac Pro -- could you add another identical 3.33GHz quad-core processor to a second socket?

IMac :: Which I5 Processor Is Inside

Jul 30, 2010

I see a great deal of debate between the quad i5 and i7 but nothing between the two i5's. I'm not super techy so I really can't tell what the benefits or disadvantages there are between the two. In fact, I didn't even notice that there are two different ones until I was poking around on apples site.


3.6 i5 with 4mb lvl 3 cache and HT and TB


2.8 quad core i5 with 8mb of lvl 3 cache with TB but NO HT

*you can build identical iMacs both with the 5750 (5850m) and the 3.6 is only 50 bucs more.
