Memory problems, need help.

Hi everyone iam a total noob in ram tuning. 

 

a week ago i build myself a new pc , the gpu is from my old pc.

The problem i have is that i cant get RAM to work at rated speed 3200mhz cl18-22-22-42, if i enable XMP profile it crashes even at 2933mhz . So i started to tune my Ram manually and got some results.

the system is stable at 2800mhz   18-22-22-42 1.35v 1T Gear 1 anthing above that its unstable at those timings.

so i went back in bios and left timings and command rate on auto and manually bumped the frequency  to 2933mhz and the motherboard choose these settings : cl 21-21-21-47 2T Gear 1 and its stable. 3066mhz is unstable at the same auto settings.

 

In gear 2 everything works perfect at rated speed and timings 3200mhz cl18-22-22-42.

 

so my question is whats going on ? what should i do to achieve rated ram number in gear 1 or close to rated .

should i just run in gear 2 ? or try to lower the timings at 2933mhz cl 21-21-21-47 2T Gear 1, i use this pc for gaming so iam only interested in fps.

 

RAM is in correct slot 2,4 i tried to move it to 1,3 and the result was the same.

I’m not exactly sure why you can’t reach your desired settings but the difference between 2800 MHz and 3200 MHz (with the same timings) will be unnoticeable outside of benchmarks, especially with an Intel CPU. In gaming it could mean less than 5 FPS difference if you are CPU bottlenecked. 
Basically RAM speeds, especially a difference of ~400 MHz, will not be noticeable in the real world.

2 things, Depends on

 

The CPU 

And the Motherboard

I have a 2400G And 3200MHZ LPX Corsair 16GB RAM

Still cant go 3200, stuck at 2666MHZ

 

 

Id say get a new MOBO or your gonna have to bank out
