I've been playing around with the settings on my nerdaxe gamma from @Solosatoshi.com πŸ‡ΊπŸ‡Έ and gathering data with just the default hardware. Looks like I hit the limit for the stock hardware at about 625MHz and 1.25V at which point both the ASIC temp and VR jumped significantly. The Charts are raw data collected over multiple hours at each setting and the averaged data over same time periods. Next step is to swap out the heat sink to one of the Dark Horse Heat sinks from @Solosatoshi.com πŸ‡ΊπŸ‡Έ and then repeat the data collection.
