    Honestly, I think that you're doing pretty well @3333 using four dimms. Pushing hardware to the limits always has some risks and only you can decide what your tolerance level is. That voltage is creeping up there but, you're correct about the ddr4 spec. Keep an eye on your dimm temps and keep some airflow over them you should be OK.

    Thanks for the link to debauer's vid. I'll check it out. I'm actually satisfied with anything above 3000Mhz.

    I can confirm using TridentZ RGB sticks that I've only been able to get 3000MHz speeds stable u sing 4x16 GB. As these are Samsung B-Die, they are Dual Ranked I believe. I can get 3200 rated speeds if I remove 2 sticks, but that's not fun.

    Same thing here. I have two 16GB kits of FlareX 3200 Cas 14 that seemingly used to run well but I'm seeting anywhere from 0 errors to about 10 in memtest86. Sometimes it comes out clean which is what bugs me.

    I've tried Ryzen dram calc, just upping the ram voltage. Ive even tried different kits all together. Im seeing that as soon as I go from 2 to 4 dimms there are errors. While it seems stable its not.

    This is with a 2700x.

    Im showing on auto that the SOC voltage is about 1.115 but Im going to try increasing it manually.

    I'm wondering if the CPU degraded somehow because I dont remember this always being unstable. The only thing i know that changed was the bios.
