3693.4 Mhz RAM with bclk tuning. 4381.7 Mhz CPU as well. Latency at 68 but performance in general has improved the most vs all other configurations and there have been a ton of changes during this burn in period. I’ve decided to save up for better RAM because I’m pretty sure my if could handle 1866mhz with ease. But my ram can’t without loosening the timings to the point of no benefit.
