Not a huge impact, but not insignificant either on a week-long run of simulations, it might cost me another hours. I could easily remedy this if necessary, but simply pulling the last 2 sticks, leaving me with 48GB in a proper triple-channel setup. Step 3: New CPUs! This section is not for the faint of heart, and if done wrong, could easily render your Mac Pro a very heavy, expensive, paperweight or at least cause lots of expensive repairs to be done.
I downloaded the firmware update utility, downloaded the latest 5,1 firmware, and ran the utility. My machine shut down, and I held in the power button until it beeped. The firmware took a few minutes to update, and I soon found myself back in the finder. The next step was to determine how I wanted to upgrade the CPUs.
Instead, the CPU die is all naked and exposed. This results in 2 "gotchas": The CPU can be more easily damaged during installation as it doesn't have the protection of the heat spreader and More importantly, he point of contact between the heat sink and head spreader-less CPU sits a couple of mm lower than one with a heat spreader.
So if you use a generally available westmere Xeon with the heat spreader , and tighten the Mac Pro heat sink all the way snug, you will likely destroy both the board and the CPU.
Can I upgrade my MAC PRO with another Motherboard or better CPU?
If you dont tighten it all the way down, the fan connector which is integrated into the heatsink may not engage the board, and the machine will not boot. So your options are: Use normal Westmeres with a heat spreader. You can snap off the heat-sink fan cable connector and lower it a bit, making sure it engages. You will also need to either be extremely careful tightening the heat sink down turning it roughly 4 turns less than what it took to loosen it , or use some nylon spacers on the heat-sink posts to ensure it doesn't over-tighten.
To me this looked like a very good way to destroy a processor so I didnt look too far down this path. This allows you to simply put in the CPUs, and finger tighten the heat sink.

While it is nearly impossible to find from-the-factory heat-spreader-less processors, there are a few enterprising individuals who remove and sell them on ebay, or through web stores, typically specifically for upgrading Mac Pros. I opted to have faith in my own computer building skills, but not have to mess with heat-spreader issues, and found a small company in Iowa selling upgrade kits https: A few days later, my kit arrived I went with the 2x hex-core 3. The kit included a link to a private youtube video showing the upgrade process in detail I took my time, followed the instructions, and about 30 minutes later, held my breath as I powered the machine on..
After seemingly forever, the grey apple came up, the chime sounded, and a few seconds later, the About my mac screen yielded: I then fired up the benchmark programs and Step 4: You could probably save some on the memory, and if you're brave enough to go with lidded processors, you can save a couple hundred there. Conclusions I am quite happy with the upgrade. For a relatively small expense compared to buying a new machine , I've been able to upgrade my mac pro to a modern compute workstation.

Spec-wise it compares very nicely with the new Mac Pros or will once I select a video card , with the one exception of not being portable though the only times I have moved this machine off my desk were to do the upgrade. I figure with the current speed, I just bought myself another years out of this machine. That's a beast of a machine. If your application allows for it, you might be better with a multi-gpu setup power supply issues not withstanding.
I'll have to do some investigating I believe the power draw on the Black is too much for the Mac pro to handle. You use an adapter to mount it in one of the PCI-e 2. Great write up! Not a cheap exercise but the performance numbers speak for themselves.

Yes, that is what i am noticing. Since this is a secondary compute machine, I should be able to get away with just a Titan Black which has theoretical GFlops of double precision compute performance vs. The issue is that even with the Titan Black I'll need to add a secondary power supply to the mac pro in order to do it. I guess another option if I am feeling frisky, would be to get a Z, and put it in my Linux box the primary compute machine and transplant it's Black into the Mac Pro.

We Love Macs Address: When resetting the Logic Board there are 3 Mac power management reset switches that you can use to troubleshoot various symptoms: It tells your Mac when to turn off, turn on, wake, sleep and remain idle. It also handles system resets from various commands and controls the fans. Resetting the SMC does not reset the PRAM parameter random-access memory or resolve issues that have rendered your Mac unresponsive; this is usually resolved by restarting your Mac.
If your Mac unresponsive follow these steps in order until your issue is resolved: If your computer still shows signs of the Applications or Finder being unresponsive after you have restarted, then try resetting the SMC.
An alternate way to reset the SMC: The Real Time Clock located on the logic board controls the date and time functions of the Mac. If your Mac is experiencing a boot issue, resetting the RTC might resolve the problem.
The Mac Pro has a system reset switch on the logic board that you can use to restart the system while powering on. To reset the system: If your Mac successfully reboots after you press the switch, try shutting it down and restarting it by pressing the front power button. If the Mac Pro restarts when you press the system restart but not from pressing the front power button, then your power supply may need to be replaced.
