How to optimize RAM timings on Biostar A320MH PRO?
The moment I saw my frames lock above 60, I almost jumped for joy, because those micro-stutters were killing the vibe. The Biostar A320MH PRO, running D4 2666MHz RAM, had timings jumping between 16-18-18-38, which caused a 10-15ms scheduling delay when the CPU handled complex AI. I tried turning on 'Game Mode' in Windows, but it only gave me 2 extra FPS while the 1% lows stayed trash—not exactly the hardcore fix I was looking for. I went into the BIOS, switched the memory preset to Manual, crushed the tRFC from 600 down to 540, and bumped the DRAM voltage to 1.35V. Using RivaTuner, I saw the frame time variance shrink from a wild 20-32ms down to a steady 12-16ms. I actually BSOD'd upon entering the game the first time I tightened tRFC, but backing it off by 20 units fixed the stability. VRM temps are at 55-61℃, and RAM is sitting at 52-56℃. It's finally playable.
