After a bit of research, ive been able to locate some of the RAM settings in my BIOS. Honestly you should try tweaking RAM as well as CPU clock speed if you want improved fps.
Before I had no access, I had 1600Mhz DDR3 at 11-11-11-28. All i did was bump up voltage from 1.35 to 1.5, increased frequency to 1866MHz and increased tREFI to the max. Wasn't able to get 2133 working with my limited knowledge though unfortunately no matter how much i loosened the primary and secondary timings.
CPU: Intel Core i7 5700HQ @ 3.6GHz (HT on) core affinities 2-7

GPU: NVIDIA GeForce GTX 960M 2GB stock with 417.35 drivers

I wasn't seeing 100% CPU utilization on any active cores relating to TF2 before. Now i see much closer to 100%, which i speculate is due to NVIDIA and their copy system to the system RAM (optimus bleh). I say this because before I was getting lower FPS the higher resolution I went. Before I was getting about 21GB/s in memory tests at 80ns. Now I can get 26GB/s at 69ns. May be i'm wrong and these are expected gains from RAM tuning idk.
