I've just got a i5 6600K paried with a H110M-D motherboard and did not overclock the cpu. The benchmark I got from cinebench r15 was 584 (comparing to stock i5 6600K it should be around 600) and for Geekbench 5 i got a single core score of 991 and multi-score of 2994. These values are pretty bad comparing to the ones online with stock. Also, when I'm playing CSGO, I sometimes have stutters and also a low fps (100-150 on 1080p with everything low) and the GPU I'm using is a RX580. I'm also using a single channel 8GB 2133Mhz RAM if that helps. I've checked the CPU temps and it has been reasonably cool under load (around 60-70 degrees Celsius). I've also just updated my BIOS to the latest verision. Anything I can do to improve the performance? Any help would be greatly appreciated.
