my current memory kit is gskill ripjaws v 2400mhz cl17 (8*2)
what i want to know is what speed is should run it at?

stock 2400mhz timings are 17 17 17 39 55
when i bump it upto 3000mhz 18 21 21 48 69
for tighter timings on 2133mhz 15 15 15 25 50

Now i only wanna play with speed here not timings because last time i played with timings on my vengeance lpx cl16 2400 kit i think i fried one of the sticks,luckily i was able to get the current kit in place of that so dont wanna take that risk again here.
Also what i have noticed that 2133 gives better performance than 2400 and equal or a bit less than 3000 but thats just what i felt,didnt ran any memory benchmarks or anything.Plus running the memory on 3000 also increases the cpu temps by around 5C and as I also OC the CPU the temps sit around 64-68 around heavy gaming.so if performance gain isnt much then this increase in temp also aint worth it

You might find this helpful, tons of games tested using 2133 vs 3000 and only 1 game showed a difference other than a couple of frames. This is a 50% larger gap comparison than what you are working with so you should notice even less gains. They also use top of the line cpu / gpu and with something lower the gains will be even smaller.

Timings are in terms of clock cycles. So CL 18 @ 3000 MHz is lower (better) latency than CL 17 @ 2400 MHz or CL 15 @ 2133 MHz.

With those timings 3000 MHz offers the lowest (best) latency (except for 4th timing, which you could maybe try tightening a bit further), and best bandwidth.

I'm pretty sure whatever performance differences you thought you 'just felt' were in your head. You're definitely not going to notice a difference just doing normal stuff like desktop and internet browsing, and even in games it might not be super obvious.

64-68 degrees under load is totally fine.

Thanks i was worried about temps in the long run
