Seriously, the means of pulling out the tray to upgrade the memory is brilliantly done, the best yet that I’ve seen. I also had trouble with the Radeon HD 4870 Photoshop CS4 refused to recognized its OpenGL capabilities. One user reports that “ the Radeon HD 4870 won't recognize my HP LP3065 30" monitor at all, at least on the Dual-link DVI port”.

The problem his was fixed with driver version 2.1.9 in July 2009. Kernel panics related to sleeping the machine: although this was apparently very rare, it was a problem for me. Be sure to use the new system disk, eliminating crapware and the like by wiping and reinstalling without junk.Īfter a new installation, you can migrate your settings, applications and data using Migration Assistant. I was unable to boot with the system from my MP08. Please see the configuration page for details on the test machines. Configuring for optimal performanceĬonfiguring an optimal machine is more or less the same as any other Mac: adequate memory for the workload and a fast striped RAID for applications that require fast disk I/O, such as Photoshop and its scratch volume. Specialty and/or well-designed software that takes advantage of all 16 virtual cores will offer the best results, but few programs achieve this. Unfortunately, very few programs can use that power, think science, math and video here, not everyday photo applications.Ī variety of tests were run, with the MP09 showing the best performance in nearly all, but not every test. In effect, the MP09 is a little faster at the same clock speed, but offers 16 virtual cores capable of 50-80% more raw computing power. Exceptions include applications that can utilize more than 8 cores effectively. In most cases, about 10-30% faster than a 2.8GHz MP08, and about 0-20% faster than a 3.2GHz MP08.
