Hey guys - I had a couple of RAM questions on the box I've been working on. I did a little Google searching, but just wanted to make sure I wasn't crazy before making the purchase. I recently got a 2009 Mac pro off a friend of mine. It was a standard quad 2.66 with 6GB ECC ram. I successfully did the 2010 firmware crossflash and upgraded to a hex core Xeon 5650. So far that's working well, but I need some memory to go with it. I read that the new chip can support non-ECC as well as long as you don't mix types. Is that advisable for large amounts of ram? I was about to but 24 GB of non-ECC regular old PC1333, but I wanted to ask around to make sure it was wise. Normally this box is just going to be a regular home server, but the reason I wanted so much ram is that I'm studying for some VMware certs and I wanted to have a home machine I could run the labs on. It would be running ESXi in a nested config within VMware Fusion 7. Those servers would never actually be production in any way, I just need to set them up, configure them, and use the VMs to study for my VCP exam. I read in a few places that these chips run best in tri-channel mode, that's why I'm going with 3x8GB instead of 4x4 or 4x8. I was preferring to buy the non-ecc because it's cheaper and faster, but wanted to check if that would be unstable. tl:dr - is 24GB of non-ecc DDR3 going to give me problems on a 2009>2010 upgrade box?
