Should I optimize timings for Gloway DDR5 6000 in RDR2?
Galloping through the frontier in 4K Ultra is an incredible experience once you get the timings right. The Gloway 6000MHz kit had a tRFC above 500 cycles, which caused memory access latency to swing wildly between 70-95ns during 4K texture streaming. I first tried the 'Ultimate Performance' mode, but the RAM hit 65℃ and the fan noise was unbearable, which was a total waste of time. I went back into the BIOS, manually crushed tRFC down to 450, and bumped the voltage from 1.35V to 1.38V. My telemetry now shows latency locked in at 62-68ns, and the hitches are gone. I did have a bit of a struggle at the start—I set tRCD too aggressively and the system wouldn't boot, so I spent half an hour clearing the CMOS. CPU temps are 65-72℃ and RAM is 55-62℃. The mode switch is confirmed, though the voltage increase makes the sticks run a bit warmer.
