CN is on the case seems you can bug xtu if its really unstable. That's why you see guys using air cooling and low cache
If anyone can run 1800+ at any memory setting with core at 5ghz and cache under 4.9ghz I will eat my best chip.
hey guys if you have random double booting or haning on 19 alot or full shut downs when you just change something like voltages and bclk try to reflash the MEI in the bios and should fix it. Gets corrupted sometimes it seems or maybe just me. lol
