I have a set memory sticks I've been trying to get running stable @ 3000MHz ever since I bought my Ryzen AMD 2200G CPU back in February of 2018. The kit is:
Patriot Vipers 16GB (2x8GB) 3000MHz PV416G300C6K
I currently have the primary timings set in my ASRock motherboards BIOS to 14-17-17-36 (see image) :
My system is up and running @ 2666MHz for almost a full day now with no issues so far. I am very surprised to be see that these chips run successfully at all using a CL value 2 below the memory manufacturer's own CL rating. Is this a common ability of memory kits? Or is this done all the time?
Is the performance of running this kit at CL 14 with "poorly chosen" secondary timings still better than running the kit at a higher CL value, for example CL 15 with the most optimal secondary timings?
Is it possible the performance levels of 2 different CL values, for example 14 vs 15, could give the same performance if I set the CL value to 14 and was running the memory at that CL value with very poorly chosen secondary timings versus running the memory at a CL value of 15 with related secondary timings that were very wisely chosen?
Does a poorly configured CL 14 still beat an optimally configured CL 15 ... any day of the week?
Can you create equivalent levels of bandwidth at different CL values keeping memory speed (MHz) constant. Is 'overlap' possible? Or do the CL values represent contiguous levels of bandwidth performance?
Provided that I keep the memory speed (in MHz) constant in the BIOS, I'm guessing that the performance of running these memory sticks (or any kit really) at a lower CL value will always be preferred over anything achievable at a higher CL value. Is this the truth?
Different but related question: Is the NB Frequency of 1330.6 (2661.2 doubled) a sign that my RAMs secondary timings in the BIOS are less than optimal?
Windows 10 shows my running memory speed @ 2666MHz on the Task Manager->Performance->Memory tab but I'm assuming i'ts just reading a memory speed BIOS setting.
Thanks for reading!
