You say its unstable in gaming. Most likely your ram is getting warm from gpu heat and your low trfc is causing errors. try setting your trfc to 400, open hwinfo64 during some gaming sessions so you can log your dram temps. if it cures the issue then its simply your sticks getting to hot for the set trfc which is temp sensitive. Long term fix- increase cooling or increase trfc accordingly.
Thnx for feedback.
My RAM never gets hot as i keep an keen eye on temps on all of my components. My RAM never exceeds 35c during gaming or even heavy stresstesting as i have an fan blowing on bot dimms.
I think this RAM kit is just a dud as my FlareX kit could do much the same at lower voltages.. I might return this one and get 3800 MHz kit instead or higher speed.
As of now its running pretty good but with some mouse lag issues which i don't know what is causing this. Can be Windows, can be the BIOS, can be software, can be anything really. So i stick with it so far until new updates roll out.
