How much is the 900MHz model?
It's not a shipping product yet. PMC-Sierra has been sending out a very few pre-production samples to their biggest customers, and that ain't me. I'm not sure I even want to work with a chip in its pre-production state, that would be quite a bit of money and time only to find there were bugs in the early rev. I will most likely wait until it is a shipping product and they have some stability information before I mess with trying to upgrade a cpu board to it. I appreciate the offer though. assyrix wrote
I am just concerned about the elcas since I had several of them exploding on me in an VW320 power supply and motherboard after upgrading the box to a single 1GHz CPU (mobo rev. 007B), destroying all PCI-cards.
The 7000C-600 chip draws 4W at 1.2V core voltage
The 7900-900 chip draws 5W at 1.2V core voltage
The 5271-300 chip draws 4.5W at 2.5V core voltage
The R12K-300 chip draws 30W at 2.6V core voltage
The R10K-195 chip draws 30W at 3.3V core voltage
I have 3 O2s: a 5K-200, a 10K-250 and a 12K-300 (in their original forms) and they all use the same power supply, the Sony APS-90 Rev. N. Clearly the power supply is built to handle the power draw of any of these cpu chips. The 7K-600 chip is only warm to the touch after 5 days of running, the 12K-300 is much warmer but there is also a much larger space inside the computer without the second drive bay so there is better air circulation and I can see NO reason to cut sheetmetal or plastic. From the cpu power data, the temperatures I have observerd and the premium quality of the O2 componets, I don't believe any of these upgrades are going to cause catastrophic failure of any of the electrolytic caps. (and the Octane is even more overengineered than the O2) On the other hand, O2 and Octane power supplies are on eBay all the time at very reasonable prices, so having a spare might be a good idea even if you don't mod.
