M17x-R1 motherboard question

Hello everyone,

Two questions: Is the motherboard different for quad-core and dual-core R1's? I just swapped my P8700 (2.54GHz) out for a Q9100 (2.23GHz), and the power button responds, lights up for a very short period of time (less than a second), and promptly goes dark, never responding until the proc. is removed and placed in the socket again. No fans spin up, and there is no other response from the computer that I can see. (Removing/replacing the battery seems to have zero effect, as well.)

This leads to my second question: The first time I had this open, I made a stupid mistake, and forgot to turn the little screw on the CPU socket 180 degrees, to fasten the Q9100 in place. When assembled, the computer made a very, very quiet whining sound after pressing the power button, and continued to do so until I unplugged the wall power. The battery was still in, but it stopped anyway. I realized this right away, and fixed it, but once assembled again, it had the exact same symptoms as in the above paragraph, only there was no whine that I could hear this time. Could I have damaged/destroyed the Q9100 by doing this?

Edit - I suppose, I ought to also suggest the possibility that I've destroyed the mobo in doing this. That was why I was asking in the first place; can the mobo issued for a dual-core R1 take a quad-core, and the power it draws, etc? The CPU socket is identical for both, it's the microPGA-478, or whatever that number is.

Thanks in advance for your help,
~Tim

 

Hi Tim,
The motherboard is the same for both dual and quad core processors. You may want to try and re-install the dual core porcessor and see if it comes to life. If it does, you might have an incompatible or bad processor.

Thanks,
Gabe

 

Yes, I've considered doing this... I'm just sick of changing thermal interface material, and assembling/disassembling the thing, so I was hoping for an even simpler answer. My fingers are too sore to do it again today. Darned little screwdrivers. This'd be the 3rd time today, and 7th or 8th time in the last two weeks, so I'm waiting 'till the morrow.

Thank you!

The Q9100 is supported by the M17x (if it is one).
Now idk what you did but do what Gabe said, replace your P8700, go slowly this time and don't forget anything.

Also what BIOS version are you on?

 

Mine wouldnt start up when i replaced my CPU at first. Even though i had the screw tightened down, once i reseated the CPU, it worked fine.

 

Also try a full power drain (removing the coincell batt. etc.)
