Thank you for the friendly and constructive feedback. I am actively cooling the DIMMs now. My temps seem to max out around 41-42C, now. I could use some advice about where the peaks and troughs are in this DRAM configuration. Which settings are running closest to the applied voltage (meaning...

5950x at 4200MHz, fclk at 1900 SMT disabled

I did disable it, but it won't boot anyway, even with the settings that work for CAS 14.

I have disabled all CPU overclocking for my memory testing. I want to get CAS 15 working, but I have not been able to yet. CAS 14 is stable (although very hot), but that is because this memory kit seems to be entirely dependent on Geardown Mode for stability. The same settings will run with CAS...

The temperatures slowly climb to mid 50s because the airflow is good, but not directly over the DIMMs. I have to get some new hardware to add to give adequate cooling to my RAM. That will be an interesting project. In the meantime, I am doing shorter stability tests. Right now, I am stable...

I decided to adjust the tRFC first before moving onto trying to lower CAS. I noticed that my system seems to benefit from GDM, which may make it difficult for me to get CAS 15 stable. I was able to get a first attempt at a lower tRFC in a few different configurations with hours of stability...

I know I can get more performance out of this kit if I work on it. What I really wanted was to get my fclk higher, but the IMC does not seem to be able to support this capacity at a higher frequency, so instead I'd like to lower my timings. I'm very happy to increase DRAM voltage to 1.5 or 1.55...

Thank you for the detailed suggestions. I tried to utilize all of these settings. I have tested the new configuration a lot. Here are the current timings that appear to be stable. I'd still like to improve if I can.

The stock SOC is 1.2 for the 5950x on B550. That comes out of the motherboard. So, perhaps this has been increased for Zen3? I have tested 1900fclk with many hours of Prime95 tests, and it seems stable to me. 1933 fails Prime load tests.

I have a pretty good B-die kit, but it's 64GB, and the IMC cannot keep it stable past 3800Mhz. So, I'd like to tighten my timings instead to improve performance. My current configuration is: Auros Master B550 SOC: 1.2V with "Low" LLC. I think this is 25% although the BIOS doesn't explicitly...

I have some general questions about using these three components together: ASUS P5K DELUXE INTEL E6700 GSKILL F2-8500 I am going to overclock the CPU but I don't know where the FSB is going to end up. I see a lot of systems ending up around 3.6Ghz. I am assuming this is 400x9 for the...
