Today the chiller had not been run and the chip boots right up to 265x12, and with slight vcore increase 270x12. Also was able to reach the same 3532MHz with the same 1.856v as before. Increase to 1.888v and only clocks up to 3515MHz....just like before. 
Wait a minute.......CBB between 0 and -10C???....with an AMD chip?? It would boot up and run, just not at quite as high settings. And it definitely would not clock nearly as high even with vcore.
Very strange if you ask me.  |
Back off on the voltage a little - You're beating it to death and it shows.
I'd only volt it that high for suicide runs for only short periods of time but not for trying actual bench runs even if the MHz isn't as high. It's not wanting to clock up as high simply because it's getting too hot at the core and -10c isn't enough to keep it from overheating at 1.8v's+. It takes a temp of -18c to hit 0 degrees in farenhight (Misspelled that one for sure
) so your temps need to be even lower to safely run that kind of voltage.
