Troubleshoot 1GHz Dual Processor Swap

[videomatt]

I have a used Apple Quicksilver 1Ghz dual processor card. I wanted to use it to upgrade my 800MHz Quicksilver 2002. It will boot right up but it will never stay running for more than a minute or two. A message saying I need to reboot the computer takes over and the machine freezes. I was under the impression that this would be plug-n-play so all I have done is swap the processor card, the heatsink and the fan (the heatsink seems to get pretty hot in this short period as well).

Swapping the 800MHz processor card back in puts everything back to right.

When I reboot I see the following problem report indicating a crash of cpu 0 or cpu 1 (varies per incident):

Hello,

you need to reset the PMU first.
Then try again.

[rwm]

I swapped a 867, 733 and 533 several times in my QS and DA and never needed a PMU. But it makes sense to clear it. My reading has also led me to believe they were plug and play also. Probably not 100 percent.

Has the computer/processor been altered any from the stock OEM settings?

[M.Brane]

That mismatched RAM could be a problem too. If anything you should have the slow stick in the first slot so it sets the right timing for the bus.

I'm studying that option as well as replacing my original PRAM battery. Is that battery something I could find at the electronics/camera department of a local store like walmart or Radio Shack?

Is the first slot DIMM0 or DIMM3 ? For purposes of getting this processor issue straightened out perhaps I should pull that slow stick out temporarily. -- Matt

It should be PnP but this line in his error log, seems it's a good start resetting the PMU first.

I should know this and can't remember if it starts with the processor or PCI side. Look on the mobo and see if the RAM slots are labeled J21, J22, J23

[biggles]

They are labelled on the logic board. J21 should be on the processor side.

[M.Brane]

I think if you simply swap J21 & J22 you should be fine. Have you run Memtest to make sure it's all good?

[videomatt]

Well I've tried everything I can think of, pulled the battery, reset the PCM, booted from a cd, all with no luck. Time to look for a different processor card. I just can't see buying a new card though. At least not a $700 processor upgrade.

[Nicolas]

Try to remove the PC100 stick completely from your system!

I never had used PC100 RAM in a QS PC133 only.

[rwm]

I run all PC 133 RAM in my QS/DA especially with an upgraded/faster processor. I ran a Dual 1.33 for a year and half without issues.

[videomatt]

I installed the processor in a second quicksilver machine that I have (a 733MHz QS 2001) and got exactly the same result. The seller says he's satisfied that my claim is good and says he will take the processor back and issue me a refund. So now I'm on the lookout for another 1GHz dual proc for my Quicksilver. Thanks to everyone who attempted to help me out with much needed info. -- Matt
