Speaking of CPUs, this Mac Pro (4/5,1) that I'm using has developed issues, post-upgrade. Basically it crashes randomly, though it worked fine for awhile. I have reverted the CPUs to what were in it in an effort to better point fingers. I have also bought two more, slower/cheaper CPUs that I will de-lid and put in if it passes this test.
Not sure if the tray was bad, the new CPUs were bad (post-delidding), or whether the tray just wasn't capable of running at higher CPU speed. Or, worst of all, that it can't reliably run newer CPUs at all. If I only put in one of the two CPUs it seems just fine, though the fan control logic is pissed and I have to wear earmuffs. Both CPUs have passed this particular test, but both combinations of _two_ new CPUs fails. Disheartening, given the apparent early success. I spent about $150 for those fastest-possible CPUs, but I'm only spending $13 for two more of the lesser ones. They are basically one generation newer than what came in it, but otherwise identical metrics-wise. It'll be enough to run VMware, though, which the stock CPUs cannot now do. Whenever I _needed_ the machine running I have been putting in the upgraded single-CPU tray that I bought for a song. The machine is thus already guaranteed useful to me, it's just less of a screamer than I wanted, and paid for. Those two-CPU trays (and the machines that have them) sell for quite a premium. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
