A bit more testing now, loaded the gamer OC profile as you suggested (thanks Dumo) and changed all multipliers to 49, LLC to ultra high (or whatever the one just below extreme is) and manually applied voltage of 1.46 and it's looking good now. WHEA errors are no longer occurring (so far) and voltage is rock solid at 1.472 under load and 1.448 at idle. Going to try to increase bclk to get slightly higher core & mem speeds. Any suggestions there? Where should I try to tighten the timings on my TridentX for speed near 2600? Thanks a million!
