How do I get the Memory speed back to 3200mHz with 4 DIMM slots populated again? (9900k, CL22, P750DM3, P775DM2 MB)

[ShifflyTheSHO]

I had this CMS 3200mhz CL16 4x8GB kit off of Amazon that I returned, but I was running CL18 with stability at some timings at 3200mhz!!, but forgot what I adjusted on my motherboard (Z170) or my processor (i9-9900kf)

 

I’m trying to get back to 3200mhz so O can have some bandwidth again, and everybsetting I try drops me back to 2400mhz in the Windows environment.  It was my first attempt at overclocking RAM and it was a grand slam!  I got mad and returned them and I’m running a mixed kit of Micro CL22 and unknown cheap set that used to shut off my computer, but I split the kits up onto separate channels and I’ve been at a nice, stable 2400mhz.

 

I DO NOT WANT TO RUN 4 STICKS!!! That is so much slower on startup and in everything else; why do people only run 2 of 4 kits when manufactures gave you four and they out perform anything else with two slots?  Its like driving high revving sports car with donuts on the drive wheels.

 

But anyways, do I need to adjust anything beyond the SA and IO voltage? I can no longer seem to go beyond 1100 mV (1.1 V) on either without my system being caught in a loop.  How do I adjust the memory controller properly?
 

 I change the latency and set it to relearn, but should I try for 3033mHz?

 

dsanke BIOS, and my keyboard is off currently from having to pull the CMOS so many damn times.

 

(my processor can also undervolt to -0.150.  Should I not?)
