Bidule0hm, I did a 'find' in the Manual for 'watch' and 'jwd1'. There were only two settings entries. One for the jumper and one for the BIOS. No other mentions of it. So according to the manual, it has to be only those two.
Last night I:
- Looked again in IPMI logs to be sure watchdog hadn't reset again, it had not since the last one on 10/11
- powered down (completely) and removed the jumper for watchdog on JWD1
- booted up into BIOS (hit 'delete' while booting)
- checked under BIOS settings for Watchdog setting, it was Disabled. Now this struck me as odd. I'm almost certain that this was Enabled before. The only thing that I could think of was that by removing the jumper, the BIOS saw that it was gone and set it to disabled on it's own. I went ahead and toggled it a few times, put it back to Disabled and Saved and Exited.
- powered down again, plugged in the UBCD flashdrive, removed all RAM, used canned air to blow out all RAM slots and reinstalled one stick
- powered up into UBCD and began MemTest86 - let it run all night
- this morning I pulled it up and it had completed 8 passes with Zero errors
- powered down, moved that RAM stick to the next RAM slot and started MemTest86 again. It is currently running until this evening when I get home and then it will get moved to the 3rd slot... and so on.... I also started a log of what stick in what slot and how many passes with how many errors.
I will update again once I have completed all the RAM testing. I will be trying all possible scenarios/combinations I can think of.
