Hey guys, this is my first time attempting overclocking. I did some research and found out that using AI suite is a good way for newbies to get a idea of overclocking and if you learn more about it you can go a little more extreme and do things manually yourself for potentially better overclocking. I don't know if its a problem but I'll list you guys my specs and you can tell me maybe why AI suite has lowered my dram frequency and whether its overclocked my setup well. Thanks in advance.

CPU -> i7 6700k skylake 4ghz OC to 4.4ghz running at 1.34-36v (under 1.4v i've heard is good)

Heatsink -> Hyper 212 black edition

CPU temperature when idle between 35-45 celcius

Motherboard -> Asus z170-a

RAM -> Corsair Vengenance DDR4 2666mhz 2x8GB

GPU -> Asus GeForce RTX 2080 Super ROG Strix 8GB

AI suite has lowered my dram frequency to 2400mhz, any idea why? Is that a good thing? Should I go to bios and set it back up to 2666?

If you guys need any more details I'll do my best to provide you with them.
