4,1 flashed to 5,1?
Yes, once it's flashed to 5,1. It will perform exactly the same as the 5,1, including the max RAM capacity.
4,1 flashed to 5,1?
Thanks for the reply.75C is nothing for Xeon. Of course the fan won't spin up. From my observation, the fans are calibrated to spin up when the CPU temperature reach ~80C and keep it at around 85C.
Anyway, my Mac is a flashed 5,1, upgraded with the W3690. And it something running at 100% load continuously for a week. No shut down issue.
If you believe that's temperature related. All you need to do is install MacsFanControl, manually set the fan to 50%, and run the stress test again. 50% should be more than enough to keep the CPU cool.

sorry im new where is this tool everyone is talking about, i keep see the firmware link but not the toolUpdate the firmware to B07 and then run the tool again.
I have recently purchased a 2009 Mac Pro with the intention of upgrading the processor. I just installed a new ssd and memory and was checking to see if the memory was being read and I noticed that my mac is already on 5,1 and running Sierra. Not entirely sure how this is possible or if I am reading it wrong. Will I still need to upgrade the firmware or is it good to go?
It's not unusual that someone already flashed it before. Anyway, that's your boot ROM version?

Then you're set to go. The person who had the system before you could have flashed it already. Anyone tech savvy enough would have done so, if it can be done. Upsides. ;-) You practically got a "2010" model for the price of a "2009". Giving it at least another couple of extra years for longevity. So long as Apple keeps supporting it.I have recently purchased a 2009 Mac Pro with the intention of upgrading the processor.

Actually I found the solution on Netkas.org. The site was down for a good portion of today and I wasn't abel to search their archives.
Apparently all you have to do is this:
Download the Mac Pro Firmware update 1.5 (MacProEFIUpdate.dmg) from Apple: http://support.apple.com/kb/DL1321
With the downloaded .dmg on the desktop, double click to mount the image.
Run the Mac Pro 2009-2010 Firmware Tool. It will automatically locate the package and proceed to the next phase of reboot and power switch hold until the little light above the power button begins to flash or you hear a long beep.
There is no need to rename or replace anything. The Firmware Tool grabs the package and proceeds with the process with no 5570 error message.
Hope this helps other Mac Pro 2009 users who are attempting this firmware update.
This worked perfectly, once I found your instructions, which includes the critical step: "With the downloaded .dmg on the desktop, double click to mount the image." This is the only way running the subsequent "Mac Pro 2009-2010 Firmware Tool" will operate properly! The rest was easy - my 2009 MacPro4,1 now shows updated firmware and reports itself as "MacPro5,1". With this accomplished, it's now possible to install the very latest version of macOS Sierra, 10.12.5, using dosdude1's excellent YouTube video instructions and software tool. Here's a link: How to Install macOS Sierra on an Unsupported Mac.
Enjoy!

I have a flashed 2009 as well, which I use strictly for my design work. I have an older 2008, which I've maxed out as much as I can. But Apple has stopped support. Last supported OS is 10.11.x. I'm currently running 10.10.x on it now. Not as peppy as it used to be. But more than enough for my daily usage of emails, iTunes, and web browsing. I hope to get at least 3-4 years on the "5,1" before I have to switch over to the Trash Can. Not looking forward to that. The Mac Pro towers are the most versatile Mac system I've owned. The Trash Can is pretty much proprietary. So I'd have to get new peripherals. Especially for all my internal drives.
What does it mean by "memory rank"? I just upgraded the firmware to 5,1 but it still says my RAM speed is 1066. Can the 2.66 Quad Core CPU that came with my '09 Mac Pro run 1333 RAM?Fair enough, that's why I said you may have your good reason.
Anyway, may I know what's your plan about the RAM upgrade? IMO, it's quite hard to define best performance in the area of RAM (of course, I am only talking about the 4,1/5,1).
If you want purely max speed, non ECC RAM is faster (about 2%), but you lost the ECC protection.
If you want purely max speed, you can't use all 4 slots. However, when you run out of RAM, there will be a huge performance hit.
And if you really want 1333 RAM, you may need to pay attention on the "memory rank" as well. Some RAM may able to run 1333, but not on the Mac Pro because of that.

Thanks for the info. Not that concerned about the extra speed. Thrilled to know the firmware upgrade went smoothly fir the most part. I did a PRAM zap a couple times and it didn't upgrade the speed and was concerned it was a mistake and thus perhaps the firmware didn't upgrade 100% correctly. So glad to know it wasn't supposed increase to 1333Mhz.No, W3520 only support 800 and 1066MHz RAM.

However, I did have to restart or shutdown a few times after the firmware upgrade and Sierra upgrade. I don't know if it's because of the firmware upgrade or the macOS upgrade to Sierra, I'm guessing it's probably the Sierra upgrade … but after the upgrades System Preferences and another Mac utility would crash, it also took a while for the "mouse" pointer to show up right after a restart.
Btw, I have Guest login shutoff, but after the firmware upgrade it turned it on. I shut it off again, and after Sierra upgrade it came back on. Is Guest login turned on the default??
Sure it's the Sierra's issue, nothing to do with the firmware.
You can turn the guess account back off. It should stay off now. Anyway, if system preference crash, that's a bad sign. May be you should consider a clean install now.
If System Preference doesn't crash any more, would you still recommend a clean install? Meanwhile, sometimes my "mouse" pointer is tracking erratically and unpredictably, is that another sign of a bad Sierra install?
Is it better to do a clean install on High Sierra, or do a clean install now with Sierra and do a regular install with High Sierra? I rather do just one clean install since it's a pain to reinstall all the apps and settings. The good news for me is that I have my data in a separate HDD from the OS and apps which are on a SSD.
There's no need to change any hardware.Hi,
Can anyone could help me. I can't find the answer after reading so many threads.
Can I upgrade a Mac Pro 4.1 (with firmware b07) to a Mac Pro 5.1 firmware using the same hardware, or I need to upgrade the CPU too?
