[SOLVED] Can't set my RAM up to 2666Mhz - 2 G.Skill Ripjaws V 2666Mhz

I just bought a new ram stick 8gb. Is the same speed and reference from the one I already had (G Skill Ripjaws V 2666MHz) , except the timings are different. I cant get the sticks to run at the same speed, one is 2666mhz and the other 2133mhz. In my bios F6 (Gigabyte AB350 Gaming 3) there is no option for individual config of the sticks and also cant find the XMP option anywhere.

So... What can I do so both sticks run at the same speed (2666)?
And second, adjusting the timings manually so both sticks have the same timings is a must?
 
Solution
they wont run over the xmp settings on cas 15 one like show in cpu-z memory tab also check the special note for amd on the cas 19 one in bios and both of them are not on support list for board from ram maker so they are running max speed now and it is never good to mix ram .

UserBenchmark shows different results than cpu-z, the bench says that both memories are running at 2133mhz: https://imgur.com/a/Vqlk70L

Mixing modules (even if identical) is not a good idea and results in issues such as this. I'd remove your 2x4gb sticks, put the 2x8gb sticks in slots A2/B2 and sell your 2x4gb kit. I would also consider doing a BIOS update to ensure compatibility/stability. This should also bring back the option for AXMP/DOCP or whatever Gigabyte calls it so you can run the memory at the correct speed (makes a big difference with AMD Ryzen).

I don't have 2x4 kit, I had an 8gb stick, now i bought a new one. I'll see if I can give back the new one and sell the old one in order to buy a kit. What kind of memory suits Ryzen the best?

Oh ok, yea the links above showed a 2x4 kit and a 2x8 kit so it was a bit confusing. So yea if possible return the new stick and sell the old one. For first gen Ryzen I'd look at a 2x8gb kit @3000mhz. You could find a kit from the link scout_03 posted but it doesn't include everything. Updating the BIOS will help though with increasing compatibility/stability for your board.

Ok, so... I tried the last time, changing timings to the channel to the ones of the highest latency stick (24-19-19-19-43 according to CPU-Z). Increased the voltage to 1.360v and set the speed to 2666Mhz. And now it worked! Cpu-Z shows the right speed, aswell with the UserBenchmark, it all seems fine now. Gonna do some test on heavy games in order to check stability. If it works for a month, I'll keep the setup as it is.
