5. Your TIM didn't find itself dripped, oozed, or smeared somewhere that it shouldn't have been?
6. No loose wires on the underside of the motherbard?
7. You remember to attach all the extra power connectors on the motherboard aside from the ATX? This usually won't burn things out, but can if the mobo manufacturer didn't build in protection circuits.
8. You weren't overly aggressive pushing down on the RAM sinks that they made contact with the traces?
9. Your CPU sink wasn't grounded or touching other components or solder points?
10. If you actually got a pop instead of a fizzle, the damage should be pretty obvious. Be sure to look for humped capacitors.
I appreciate the ideas.
1. No...only standoffs with motherboard holes are installed. Same as previous board which had no problem.
2. Well....the idle temps were fine. When running the memtest86+ beta 5....it actually shows the CPU temp during the test...and it never got above 52c. The memtest86 does NOT show CPU temp while running, but since it looked very normal on previous test and at idle, ...I don' t think this is it.
3. Yes, VRM and Southbridge sinks were on with fan running
4. Used the XMP profile, but verified voltage was set to 1.5v as rated.
5. Everything looks clean.
8. Don't believe so.
9. No...the smaller CPU cooler I'm using now doesn't come close to touching anything.10. If most definitely was a pop. All the capacitors I can see look normal. But there are several underneath the massive sink over the southbridge/LSI/PLX chips that I can't see. But...when I was down close trying to get a good look....I do think that the smell is stronger right underneath the southbridge heatsink. I probably should take it off and have a look.
I have swapped the memory that was in the box that popped over to my other box, and system recognizes it fine and boots to windows.
