CH7 Bios 2703 Issues

3200 speed seems to get me the best clock speeds with 3900x. If i go back to 3600 speed - I never see my 4.5 clocks again unless manually setting them in ryzen master.

I think it has to do with Infinity Fabric - I settled on 3400 ram clock and 1700 IF clock.

Sorry, I meant when you change the frequency to 3600MHz is it after setting DOCP or are you setting that value to Manual and then setting it to 3600MHz?

Ok, so like my picture above shows my ram is 3200mhz cl14 out of the box. If i run DOCP (3200 CL14) the boost frequencies are normal or operate as "intended" with two cores hitting 4,375mhz while the rest of the cores are 3,500mhz+. one could call the configuration stock or default.

Now, if I change from DOCP to manual and physically set ram and IF frequencies to 3200mhz/1600mhz while physically changing timings and ram voltage, I get a CPU all core frequency of 4,200mhz. If I overclock the ram to 3600mhz, the CPU response is the same.

Actually, I apologize. I thought I was clear on that at the beginning. My thought process is DOCP is stock/default and Custom timings is considered overclock. Although, with a concern for high ram speeds and lower cpu frequencies, I can see the confusion.

This is kind of interesting. So, you are saying that with higher ram speeds, you are getting lower core frequencies? I don't believe thats how the CPU was "intended" to operate. I do understand that higher CPU temps yield lower cpu frequencies but from my research 3600mhz is close to the sweet spot. On bios 2501 I could easily overclock ram and CPU boost frequencies did not change a bit. Only issue was boost speeds would max out at 4,350mhz (on the 3700x max boost 4.4ghz) and default voltages were a bit on the high side.

After install Bios 2703 after installing bios 2703 i noticed an amazing performance decrease of my ryzen 2700x processor mainly in the use of image rendering. I venture to say that it has decreased by 50%. I returned to Bios 2501.

Same here. Any BIOS after 2606 results in the same (talking about official and beta and even with the latest SMU mixed with 0002). At first -- I only noticed the decrease in memory bandwidth, but then I tried CB 15 and I lost about 120 points. This is using the same multiplier (42.8) on 2606 and everything after.
