no not at your posting Nebulous.. more inline with the post above yours. Its hard to help the "cant press enough buttons for 5ghz omg!" ... I mean, really.. what can I do with that?
**As for your issue - I have flashed using similar method.. only did NOT flash ME.. Only the BIOS. I have had to issues so far with the few BIOS updates I have performed. I would use your "good BIOS" to POST and when in your BIOS menu, flip the BIOS switch to the "bad BIOS"... and go back through the flashing procedure.. this time only flash BIOS.. and NOT ME. Once it reboots.. you should have a "restored" BIOS on your previously bad save.
for your mem.. I would not use voltage below 1.5 or 1.52v for Samsung.. though it is totally feasible.. for "Auto" settings - the mobo will "find" tight latency settings... and tertiary timings. From your past experience you may have seen that the measured latency will require "x" amount of voltage regardless of timings used...
ie - ~45ns latency ; 7-7-6-20 @ 800mhz ... RAM needs 1.58v
~45ns latency ; 8-8-7-24 @ 1000mhz ... RAM needs 1.58v
With that in mind - I think the Auto timings are too tight for the voltage you are running.. causing your RAM errors in POST. Try to keep voltage at least 1.5v and clock from there. While I dont advise it to others - I have been torturing my Samsung on this board pretty tough... running +2400mhz, 9-12-12-17 with ~1.76v... they are very stable and have taken the punishment very well... Over three weeks of 2D and 3D testing at those speeds or higher.. with voltage up to 1.84v so far.
...point being.. dont be scared of giving them 1.57v to clock and play around... 1.6v is relatively safe for full 24/7 in my eyes. *No hard feelings either.. just had to rant a bit.. folks have to understand.. we are all here to help and learn.. but no one has a 'magic wand'. At some point everyone has to pitch in and start with a little ground work of there own, to give the details needed to those that can help.. otherwise its just a cry in the dark.. know what I mean?
Ahh, understood. Again my apologies. Now to get to the issue at hand
I tried your suggestion about flashing the bad bios and tried your method twice. Once it completed and was trying to reboot, it does the same on-off-on-off cycle and fails to boot with bios switch to "A" bios However I did notice that while in good bios "B" while Re-flashing the bad "A" bios upon completion the debug LED displayed 15, which I thought was a sign of life. Once it shut itself off and tried to reboot, that was the end of it. Same results: On-off-on-off-on-off cycle and doesn't go beyond that point
As for the sammys: I manually set the timings for 1600@ 11-11-11-28-1T Dram voltage @ 1.6v and rebooted. No problems. I went back into bios and tried just 1866 with same timings/voltage and again it failed to boot I've pretty much given up on these. Awaiting on G.SKILL Sniper Series F3-17000CL11D-8GBSR as the Kingstons I was going to get tested faulty and were RMA'ed.
Appreciate the help and suggestions.
