Zdnet Clock Overclocking For Mac

With a proper liquid cooling system, Xeon & i7 can gain up to 45% clock speed. For example, hexacore Xeon W3680 is rated 3.33 GHz. I\'ve been running it at 4.7 GHz on a PC for over a year now without problems, it\'s cool by a large radiator with four 120 mm 2000 RPM PWM fans. So it is definitely loud when running it at full load, but it has saved a tone of times as I do a lot of renderings.Overclocking Mac Pro is not recommended, because it is engineered for to be a quiet workstation. That\'s an important feature in a office environment.

The downside is its air cooling system can\'t handle anything beyond the minimum clock speed. So if one would overclock a Mac Pro without changing to a better cooling system, it would overheat and lockup, potentially damaging the hardware permanently.BTW, more RAMs would launch applications and load files faster. But they would not add any advantage to CPU process tasks such as rendering images and videos. Mac Pro uses UEFI and you can\'t go in.A dual Xeon is harder, though as the eVGA SR-X and SR-2 showed it is possible. Though there most go for buying cheaper processors and then OC - rather than start with a pair of X5680s @ $1600 each!!Games love high clocks and don\'t need 8 or 12 cores.You can build a nice PC for the cost of one 5680, GPUs extra for sake of it as you can spend $250 to $1200 on 2-3 nVidia GTX 680s.You cannot easily put 2-3 GTX 680s in Mac Pro and no support for SLI.

In a rare example of the PC\'s performance tuning culture translating to the Mac, a new utility has surfaced that lets Mac Pro owners overclock their systems beyond Apple\'s official specifications.

And there are advantages to some pro apps havng a GPGPU one that requires some 8-pin cables.The G5 LCS was a mitigated disaster for about 50% of the units - the Quad G5, the 2,7DP. I could not hear myself think with those G4 MDD 1.25DPs.My Mac Pro is my space heater.

Short form: Dunno.Long form: Maybe. I do recall some Russian forum that showed how to overclock a Nehalem by (boy, I really hope I remember this right) cutting or shorting some of the PLL (?) leads going to the processor. It\'s the only hardware or \'pin mod\' I\'ve ever seen for a Nehalem.If its something you want to try, download the processor data sheet & try to figure it out. The downside is that unless you are really good at reflowing circuit boards things get kinda permanent.Personally, I\'ve always been big on voiding my warranties early. Up to you tho\'.R.

There WAS a software overclocking tool for Mac Pros (ZDNet Clock) that I played around with before, but it seems to be broken in Mountain Lion and will probably not be updated. I think it would still work if I could get past the message saying that \'you need a Mac Pro to use this tool\'. Sad because I wanted to try a real speed test with it just once.But I do not consider overclocking a Mac permanently a good idea. Lots of fuss and lots of risk with very little benefit. More RAM is a cheap speedup for your Mac, unlike mine.
