The Sonnet QuadDoubler replaces the CPU in a Centris or Quadra Mac with one that runs twice as fast as the original ‘040 processor, and by overclocking the logic board, you may be able to achieve even better performance.
The Centris series of Macs only included three models: the 20 MHz Centris 610, the 25 MHz Centris 650, and the Centris 660av, which is identical to the Quadra 660av. The 660av is covered on Overclocking the Quadra AV Models.
Every Mac Quadra can be overclocked, although the method varies among models. The Centris/Quadra 660av and Quadra 840av are covered on a separate page.
The AV Quadras stand apart from the rest of the Quadra line with their AT&T Hobbit coprocessors and GeoPort serial ports. both the 660av and 840av can be overclocked.
Only two Mac LC models can be overclocked to improve performance. The LC II and LC III can be chipped; the original LC and LC III+ cannot be overclocked. You can also upgrade LC models using third-party accelerators the plug into the LC processor direct slot (PDS), which will bring more performance at a higher […]
Some of the old 68030 and 68040 PowerBooks can be overclocked to achieve improved performance. This page has information on the PowerBook 140, 145, 150, 160, 170, 180, and 520 and 520c.
Not all Macs can be over clocked, but three models in the Mac II lines can – the IIsi, Iivx, and “wicked fast” IIfx. These pages provide information on the maximum reliable speed, which may vary from one machine to the next.
Many Mac models can be “chipped” to run at a higher speed, but none of the compact Macs can. That said, some can be upgraded with third-party accelerators, so you’re not necessarily stuck with the original CPU speed – although finding those upgrades nowadays may be difficult.
Where were you on 9/9/1999?
Do you have more than one iDevice with different versions of iOS? Syncing them on the same Mac can be difficult, but here is a simple trick.
As widely rumored in recent months, Apple unveiled the iPhone 6 this week – and in the two sizes expected. The smaller model, with a 4.7″ display, is called the iPhone 6. The larger one, with a phablet-sized 5.5″ screen is the iPhone 6 Plus.
My attempts to revive an old iPhone have finally come to an end. I say good-bye to this beat up beast, but it’s not all bad news.
After months of rumors, Apple finally announced the iPhone 6 and the iPhone 6 Plus. Is it what we expected?
While the world was busy saying hello to the new Apple Watch and iPhone 6, Apple quietly said farewell to one of its most iconic products, the iPod classic. Indeed, after nearly 13 years on the market, the device that defined and dominated the portable music player industry is no more.
With its 5.5″ display, the iPhone 6 Plus was very competitive with the largest Android smartphones and phablets, which had helped Android cut into into iPhone sales.
The iPhone 6 broke with Apple’s traditionally small displays to keep the iPhone competitive with the larger Android smartphones that dominated the market and were cutting into iPhone sales. The iPhone 6 moved to a 4.7″ display from the 4.0″ of the iPhone 5 family, while the 6 Plus was a substantial 5.5″.
I am a huge fan of Mophie products and picked up a Juice Pack Air for the older iPhone 3G/3GS. This is a mini review.
Unlocking an iPhone in the UK isn’t always as easy you might think. Sometimes it’s impossible. Here’s why.
Have no mobile data? Here is the third and final instalment in my using only free WiFi on your smartphone.
Last year, I was excited to review a manual typewriter from Royal. Yes, you heard right – a manual typewriter. In 2012, the manual typewriter was declared dead. The death of the manual typewriter had been greatly exaggerated, as was proven when I reviewed the Royal Scrittore from Hammacher-Schlemmer. Unfortunately, my excitement turned to disappointment as I […]
If you’ve been on Facebook this weekend, chances are you’ve seen a link to a Cult of Mac article entitled See How Mac Magically Decluttered Our Desks Over Past 35 Years. And if you saw it, you probably clicked on it and saw the animation showing how that took place.
Road Apples. That’s our category for the worst products Apple ever made. Products such as the Apple III and the Performa 5200 that just had to many compromises or reliability issues for us to ever recommend using them. We think it’s fitting to name them after horse droppings.
Dropbox for your mobile offers a superb over-the-air Photo Stream alternative for older iPhones, Androids, and other platforms.
I finally did it: I bought a smartphone. And a halfway decent one at that. My new weapon of choice is a Motorola Moto G, a device that touts a near-stock Android experience, a quad-core CPU, and a camera that… well… okay, it’s better than the one in my old phone. Storage capacity is only 8 […]
I’ve been using Classic Mode on G4 Power Macs for years, but now I have a 2.3 GHz Power Mac G5 with dual processors. It can’t boot Mac OS 9 natively, but it can run Classic Mode. How fast is it?
When Apple introduced the Power Mac G5 in June 2003, it made a big deal of the G5 being a 64-bit CPU. It even mentioned that on the box. But what does that mean to Mac users?
PowerBooks don’t look or feel like “regular” Macs, but they are just as powerful as desktop Macs, sound like desktop Macs, and even smell like desktop Macs.
Someone in our Facebook group asked an interesting question: “Anyone know the maximum size flash drive that can be used in OS 9.2 on a 300 MHz iBook G3?”
Second Class Macs are Macs you should buy with your eyes wide open – if you buy them at all. The only ones I would put on the “avoid at all costs” list are those with three or four apples. The Macs with only one or two apples can be very nice computers as long as […]
This is the fourth in a series of articles showing how Adam Rosen uses four vintage Macs to read, recover, convert, transfer, and return files to his clients. Today he shares how he uses his Power Mac G4 Cube running OS X 10.4 Tiger.
