I picked up a used Dual 1GHz cpu card to replace my single 933MHz in a Quicksilver 2002. UNI-N revision is 11, boot rom is 4.3.3...so it should support the dual proc.
Dual daughtercard in, and all I get is the PSU turning on and staying on, power button on the front goes dim, red led on the MB lights up, but no startup sound or monitors waking up. I've even tried touching the CPU's and they don't get warm. I've pushed the PMU reset button a couple times, but no result. I've got a few spare PRAM batteries around in case I've drained the battery too low - could that be the culprit?
Put the original CPU back in and it boots up fine - and I reset date/time. I've been reading many similar posts, but haven't found the answer. The lack of heat makes me think either the dual cpu card is bad (!) or it's not getting enough power to run. Some posts mention 12v coming to the daughtercard via the metal standoffs. I've lightly roughed up the shiny metal rings around the mounting holes of the daughtercard to assist in a clean contact, but still nada. Also, I've got an old SCSI card and a SATA card and 2 drives in there. Is it possible I'm maxing out the PSU, keeping it from powering the dual cpu card versus the single?
