Bad B1 slot (with no visible CPU pin issues)

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have four sticks of compatible, identical (according to the bios details) ram. All four work in any combination in a pair in A2+B2.
All four boot in A1.
When any combination is in B1 solo, or A1+B1, or all four slots, the computer doesn't boot. No beeps. Infinite restart.
I've checked the CPU for pin damage band see nothing.
I've tried running at auto ram speeds, DOC, or lower than default speeds, none of which make any difference.

Can anyone recommend any other steps to take?

I don't really feel like buying other RAM and/or CPUs, as I believe they are both fine, but any other logical steps/tests would be much appreciated!

	In case anyone searches for keywords in this message in the future, in this case it was a CPU issue, one or more pins must have been damaged during installation/removal. A new CPU and the slots work fine.
