I updated to K and i got much better memory frequency from the previous J BIOS. I couldn't get my 3333mhz at cl16 rated memory to go any higher than 3066mhz on the J bios without having memory errors. Now i'm at 3266mhz at cl16 (rated timings) for almost a week without a single crash.
On the other hand, overclocking the r7 1700 has been a hassle, i can get it to 3.8ghz at 1.32V stable, and 3.9 at 1.45V to get it stable. I have a good cooling solution but i feel i'm already stressing the VRMs at 60 degrees (wouldn't let the cpu go higher than 70 degree at load). i feel i probably wasn't lucky at the silicon lottery or is it the same with everyone else?
Also now that AMD confirmed that Zen 3 processors are supported on our boards, should i wait for the new cpus or go for the 2700x? (my question is mostly related to the benefits of upgrading also the motherboard if it would have any performance repercussions).
