@JohnnyDirect thank you for going to the trouble, it is appreciated. This is good news as now I can start tweaking my score.
I was thinking V-sync because, before I swapped back to my 1080p monitor my score was 2490 every time. Then when I switched to the 1080p monitor I forgot to go into monitor settings and set it to 144htz so it was running at 60htz and my score was again 2490. Set 1080p monitor to 144htz and score went up to 4220 and stayed the same when I went back to the 4k 60htz monitor. I don't know why I was stuck at 2490.
Will raising CPU cache help improve my score? It is currently 200mhz behind core because it takes a lot of voltage to get it running faster but I could give it more voltage for benching. Also would raising the memory multiplier help or would I be better tightening the timings? My system mem is a bit lame, not great overclocker and only 3000mhtz 15,16,16,39,2T (was one of the first DDR4 batches from Kingston)
