Cool. This is my first time also swapping CPUs in the Mac Pro. I have a 4,1 so I'll have to flash to the 5,1 firmware before I can install it. I am running Titan SLI so I'm good in the graphics department for a while too. I'm upgrading from a W3540 2.93ghz so I'll like the single threaded speed increase.I got a W3680 for Christmas, and I just installed it into my MP5,1 that came with the 2.8 quad core. Very noticeable increase in the responsiveness of the machine. Along with the HD 7970 I installed, I am good for a while. By the way, this was the first processor swap I have done in a MP. I just took my time, and everything turned out great. Temps are right where they were with the 2.8 quad chip.
I don't think so, the Mac Pro 4,1 is practically identical to the 5,1, which Apple sold as new until now... I don't think they could drop OS X support for at least 4 years more for these machines, imagine what all the 5,1 users who bought the Mac Pro on 2013 would say, I'd definitely be pissed.The thing that worries me about spending ~600 for one of these processors now is that future OS upgrades may be stopped for my 2009 Mac Pro. I believe it is already on the border of being allowed for Mavericks. I think if you upgrade the firmware, it can be spoofed into thinking it is a 2010 model so it may last another year like that.
I couldn't with the Titans installed and doing it blind or with them removed. The Mac Pro needed an EFI card installed in order for the flash to work I guess.Awesome! Love my 3680s.
Were you never able to get the 5,1 flash working?
Oh, that's good. I'll def keep my GT120 around for times like that.I couldn't with the Titans installed and doing it blind or with them removed. The Mac Pro needed an EFI card installed in order for the flash to work I guess.
Popped in the 8800GT and worked on first flash.
You need the 5*** CPUs in the dual processor system.Hey guys, I have a 4,1 that I am recently upgrading (See sig). I just installed my GPU today.
I'm interested in updating the CPUs in my 8-core. It sounds like 3680s are about $600 each, which means I'd be spending over $1200 to upgrade my CPUs - assuming I can find them for that price.
My other thought was to put in a pair of the stock 2.93MHz quad-core processors if I can find those to replace my 2.26MHz quad-cores. Does anyone know a good source for them?
I'm trying to make my Mac relevant for about 3-4 more years until I get a 2nd or 3rd generation nMP.
I'm also worried about investing in a system that might lose OS support soon. Would updating to a newer 5,1 style processor and flashing to 5,1 mitigate that problem or do you think 4,1 will maintain the same OS viability as the 2010&2012 5,1 computer?
Hex is the most cores available in a single CPU in the 5,1 series.when updating the 4,1 to 5,1 firmware, is the only available upgrade a hex, or could you go octo, or even deca?
There are also non-XEON options:Any W3500 or W3600 below will work in your 5,1. These are the only chips that will fit.
