i5-2500K at 4.5 GHz should give you something like 180ish (guess)
Scores have become a bit slower now with all the exploits-fixing updates. Stock i5 with stock Turboboost and stock dualchannel DDR3-1333 c9 used (in the past) to give ~222. With fixed all-core OC at 4 GHz and DDR3-1600 c9 you still get <200 now.
Did you do a typo and did you mean 195 and not 295?
You are running your RAM in dual channel right? If you are running with 2 identical sticks of RAM, that should be in the 2nd and 4th from the socket on your motherboard.
The i5-2500K at 4+ GHz is rarely the slowest in FAF. I host a lot and tend to host with CPU limit of 210. I used 200 in the past, but it seems all scores have gotten slightly worse some time ago.
The real curse is the laptopplayers with their Thermal Throttle...
You might also want to check your cooling. If untouched since 2011, the thermal paste might have degraded into dry powder...
Now that I read your nick; I might have kicked you if I remember right
. Feel free to ask me for advice on FAF anytime. I just hate lag and am happy to help you solve it.
If you run too much junk besides the game, the 2500K will get too much load btw. That is why I sometimes run the "!streams" command in Aeolus and kick if I find a streamer in my lobby before the game starts
