better cpu performance???? how???

Recommended Posts

Posted · Original PosterOP

i bought 3000mhz corsair vengeance memory sticks 2x8gb, so basically in cpu z when i execute the benchmark it comes with, the scores i obtain are higher when the memory is set at 2133mhz instead of 3000mhz, so now should i leave the memory at 2133mhz for better cpu performance???

 

it is as if lowering the mhz speed of the ram freed up resources for the cpu to use so it can run faster??? is that so???

the cpu is overclocked to just 4.5ghz cause im waiting for a better cooler i ordered to arrive

What are the timings. Might be that you can achieve much lower CAS latencies with that lower clock speed

i think the timings are the same as if the memory were running at 3000 mhz, because i still left the xmp profile active, maybe the timings have been changed automatically??? lowered automatically by the xmp??

i guess ill just have to experiment around a bit to see how far i can push those down, ill google around a bit more also

Tbh this seems more margin of error than anything

maybe, cause its just a little bit better, is lower cas latency better for gaming??? i wouldnt see any other reason to keep the mhz low otherwise

CPU Z benchmakrs sucks. The score can vary drasticaly between each runs.

The stress test is useful though

in cinebench r15 the cpu score is higher when the memory is at 3000,as i would expect , i guess its just cpuz then 😄

 

the lower score is the cpu with memory at 2133
