Underperforming PC?

[Kenna]

 I have installed a ryzen 7 2700 however my PC performance isn't as good as it should be, though even with my old ryzen 7 1700 I had some performance issues. In games I get lag spikes and stuttering quite a bit. Games in question being fortnite, Witcher 3 and COD WW2. In cinebench R15 I haven't been able to breach the 1700 point barrier and this is with 2700 being oc'ed to 4.2ghz.

Not sure what is bottlenecking my performance.

Full PC specs are:

Ryzen 7 2700 @4.2ghz

16GB DDR4 @2666MHZ

Asus turbo GTX 1080Ti

Asus x370 prime pro MOBO

Intel 512gb 600p drive 

2 TB HDD (not sure the brand)

CoolerMaster AIO CPU cooler 

Acer x34 3440x1440 ultrawide gsync monitor

 

Bios is fully updated

 

I tried overclocking the ram to 2933mhz by increasing the stock dram voltage but performance was very bad, chrome especially was basically unusable with major lagging and stuttering, CPU also didn't clock any higher than 3.2ghz instead of the 4.2ghz clock I had, cinebench R15 performing dropped to just over 1100. Maybe I didn't increase dram voltage enough?

Stock it should be around 1500, and overclocked around 1700 - 1800. Is the CPU OC stable?

Yeah, I have a mate with a ryzen 7 1700 @3.95ghz and his cinebench R15 score is also around 1700.

Though for me the main issue I have is lag spikes/stuttering in games

my CPU has a cinebench R15 score of around 830CB and i have no issues with games running at 1440p high-refresh high/ultra settings or rift VR 1.4X supersampling with GTX 1080 it's stupid smooth in all scenarios so there has to be more tha that to it
