I currently have 10.6.8 installed on my Samsung 830 256GB SSD.
I guess it would not work to just keep booting from this drive if I upgrade firmware, would it?
Yes - But I would clone that drive so you have another boot drive available just in case. Backups are so very important
This thing is way too complicated
This really makes the 2x W5590 route appeal way more to me..
But I want 12-cores
Why? Are the applications you use multi core aware?
Especially since the X5650 is pretty much the same, if not cheaper, then the W5590. + It's more powerful (atleast multi-core wise)
Currently 2x 2,26GHZ Quad Cores installed (Mac Pro 4,1 early 2009)
HUGE Snow Leopard fan
- really.. I don't want to change...
Currently got Snow Leopard (obviously
) installed on a 256GB SSD (10.6.8)
I want to upgrade to either W5590's or X5650's.
2x X5650's which would be quite abit snappier then the others, They also would allow me to use 1333mhz RAM.
W5590s would also allow you to use faster RAM. Why do you think X5650s will be snapper? The clock speed (2.67 GHz is a lot slower than the W5590s at 3.33 GHz, and again if the applications you run don't utilize the full 12 cores, the W5590s will actually feel snappier.
Talking about safety: If I want to use the5650's, I also would have to run the firmware update/hack. I don't know why, but I am kind of scared of it.
Again, if you back up your startUp disk, that removes the risk.
For example: Let's say I upgrade my firmware now (still using the default CPUs). Then I turn off my Mac (running 10.6.8). Would it still boot?
I Believe the answer is Yes, but if not you could always revert firmware.
Theoretically it SHOULD since I have 10.6.8 installed, which is compatible with the 5,1. On the other hand, I used the 10.6 Retail DVD to install it and then applied the combo update. I'm way to unsure...
AGAIN - BACKUP YOUR BOOT DISK
Another example: Let's say I did upgrade my firmware and CPU and everything is working fine. Then one, or even both CPUs die. Would the old E5520's still be compatible with the 5,1 firmware?
Yes!
Waaaay to much to worry about, just because I love 10.6 so much
