How to fix memory scheduling on Corsair Vengeance RGB DDR5?
Whenever I hit those high-density foliage areas, the Corsair Vengeance sticks started acting up, with memory latency jumping wildly between 65ns and 82ns. It honestly made me question the binning of these chips. I first tried just slamming the XMP profile to the max, but the system just straight-up rebooted during complex map loads, and the core voltage around 1.35V was all over the place. It was a total nightmare balancing stability and speed. I eventually dove into the BIOS, locked the primary timings at 32-38-38-76, and focused on dialing in the tRFC to 480 cycles. Using HWiNFO, I saw the read/write speeds climb from 52 GB/s to 58.4 GB/s. I did have a few crashes early on due to calculation errors, but bumping the DRAM voltage to 1.4V finally nailed it. Temps stayed between 48°C - 53°C, and loading times dropped from 15s down to 9s. Messing with low-level timings is a tedious grind, but it killed the input lag completely. Frame times are now rock steady at 5.1-6.4ms.
