Benchmarking Asgard Valkyrie II DDR5 in Final Fantasy VII Rebirth
I wanted to see how a dual-channel bandwidth bottleneck would mess with particle effects in Midgar's neon-heavy areas. Using a stress test module to quantify memory bandwidth, I saw the frequency wobbling between 2465 - 2595 MHz. My projections showed that without a fix, the frame pool interval would stay stuck in a high 6.8 - 10.9 ms range. The first benchmark run was off by about 7.2%, which was annoying. I had to dive into memory timings and optimize the voltage curve to smooth things out, which finally pulled the frame pool fluctuation down to 4.4 - 5.7 ms. The memory controller power is sitting at 11.9 - 14.3 W, and there's a faint coil whine at night. Cross-referencing the data confirmed that quantifying the throughput is the only way to pinpoint the bottleneck. It was a struggle with thermal peaks at first, but it's stable now.
