dont beieive that cpu's and computer hardware have a break in period but i am seeing something to which could be called a break in period with several days having passed

The TIM might have had a chance to settle in that time tho, leading to a bit cooler temps?

Are any 2500k users having issue reaching 5ghz? Just trying to gauge how well this board overclocks. Seen mixed reviews. Will be on water (EK Supreme HF Plexi/Nickel) in the same loop as a 6970 but with a XSPC RX480 and a MCR220 + Appropriate number of yates in pull.

I have 2600K not a 2500K, been folding for almost a month straight now at 4.8Ghz at 1.43v on water, original UEFI, temps in 60's on a water loop of Iwaki MD-20, Dtek Fusion v1, and thermochill PA120.3 that hasn't been cleaned out in 4 years(can't even imagine what the block looks like on inside). Board easily benched at 5100Mhz and that's all I have done... But its been solid, without a single crash at 100% CPU, and a 460GTX at 100% for about 4 weeks, it's just an opinion but I think the board could do 5Ghz 24/7 without issue. I experimented with 5Ghz and I just needed too much voltage for folding stability, but I think I don't have a great clocker of a CPU either.

Now one could argue that the board is what is requiring the higher Vcore to achieve stabilty, in my experience over the years the better the Vreg circuit the lower Vcore you need for stabilty. Maybe this board doesn't have that, maybe it does, but I can say it's been stable.
