9Gen memory controller (IMC) design
Thanks for the feedback! I might try 3733-3800 next and observe the results. I recall reading that all Gygabyte Z390 boards use a T topology, though I'm not entirely sure. Just checked—my Corsairs are running at 2933Mhz with 1.23v, both auto, VCCIO at 0.950v and agent voltage at 1.050v. Would increasing them affect CPU temps?
It's B-die too, just a lower bin. 3200 CL14. The system is running at 17-18-18-36 with fully customized secondary and tertiary settings. I haven't adjusted the IOL or RTL yet, but I expect changes soon. A few people say it works, but I haven't really felt much difference myself. I'm sure it does, though.
This discussion is worth exploring for more RAM overclocking insights. It often gets overlooked since it isn't flashy, but the results are impressive.
Topology should outperform a simple daisy chain with four components when executed properly, though this becomes less significant around 3800-4000MHz. Reducing their numbers also decreased CPU temperatures slightly in my setup, but a drop to 0.3V is quite noticeable. Your auto-voltage settings are acceptable; modest adjustments for stability likely won’t affect performance much.
Are you sure about challenging the 2T Brigade? I’m here to provide a serious perspective. For me, 2T is essential for maintaining optimal performance. Pushing 1T actually harms my tertiary timings and disrupts RTL/IO-L accuracy. Thanks for the read—hope it was helpful. I’m still working on refining it with more data. I asked them not to make the guide sticky since I’m short on time and think people can easily find answers online.
I possess two configurations. One runs at 3600 and 4267mhz, both rated B. The other operates at 2700x with good performance up to 4000mhz and 8700K only at 4300mhz. On the Intel board, during benchmarking at 4000mhz with a 14-14-14 configuration on the 4267mhz board, the 3600 model supports XMP timings at 4000mhz but requires slightly higher voltage—typically not exceeding 1.6v for memory.
I avoid benching and prefer constant performance. I've reached up to 1.6V, but it seems my setup doesn't adjust well to higher voltages. At 1.6V I still can't match what works at 1.4V, and I'd rather stay below 1.5V for regular use.
This setup seems efficient but has some trade-offs. I’ll monitor the voltages and temperatures closely after they arrive. I noticed the airflow was subpar because I only used two 120mm fans instead of four, which might affect performance. The cooler also had fewer fans than intended—only one 120mm versus the recommended two 140mm. Right now it’s capped at 4.7Ghz with a BIOS setting of 1.265v, AVX disabled, and AVR temperatures between 55-60°C for gaming. However, under stress testing for over 30 minutes, it risks overheating and throttling, so I want to avoid excessive scaling.
