[SOLVED] Stable overclock? Intel i5 6600K

[Isuru Kanishka Weerawarna]

My system:
CPU: Intel i5 6600K
MB: Asus Z170-K
Cooler: ID Cooling SE214
Ram: Crucial 2133MHz 1.2V @ CL 15 15 15 36 DDR4 value ram 2X4GB with custom heatsinks
HDD: Samsung 128GB M.2 + Toshiba 1TB
VGA: Yeston RX570 4GB
PSU: Zalman Gigamax 550w Bronze
Casing: Zalman Z3 with 3 Zalman cooling fans
OS: Windows 10 Home 64bit

Iam running at 4.3GHz with a VCore of 1.280V spiking on and off to 1.296V (cant go lower)
Max temps around 79C
Rams overclocked to 2666MHz 1.35V @ CL 15 15 15 36
Tested with Prime 95 small FFT and Blend test 30mins each and stable

Using only for playing Dota 2 and other regular tasks
Is this a stable overclock and is it safe to run 24x7?
Your opinion and suggestions are greatly appreciated.
Thank you in advance.

Seems pretty stable to me. May want to stress in prime 95 for a longer time to be sure.

Thank you. Is it safe to run 24x7 with this configuration?
