Utilize the Ryzen DRAM Calculator to adjust timing settings
Hey everyone, I'm adjusting my RAM timings using the Ryzen DRAM Calculator. So far everything looks fine, and I'm seeing around 10 FPS in my favorite game. I haven't run full stability tests with memtest86 yet, I'll do that later. I'm curious about some BIOS settings that don't match what the calculator suggests. There are images attached. I'm not sure how to handle tRFC since it only shows "tRFC" in the tool, but I have multiple entries in my BIOS. Also, RTT_NOM and RTT_PARK don't let me configure RZQ/7(34); I can just turn it off or set a resistance value instead. Need advice! Any step-by-step instructions on using the calculator properly would be great.
Adjust Trfc 1 by reducing the count. Make small changes (10) and check progress. Lower RTT_NOM and RTT_PARK values gradually. Test one at a time. Alongside Memtest, run OCCT in Windows. Use Linpack. Ensure minimum 50% CPU usage and full memory. Suggest testing with 16GB, reduce to 12GB, keep 4GB for OS. This should provide sufficient load.
I figured it out. RZQ equals 240, dividing by 7 gives 34, which explains the notation RZQ/7(34). It's a bit confusing. Up to now, I've just used the values from the calculator and everything is working well at CL 14 (originally 3200 MHz on a 16 MHz chip). The Hinyx ICs are actually good quality and affordable. MEMTEST86 passed.
Adjustments to timing are acceptable. They usually don’t provide substantial frequency boosts and don’t improve much with higher voltage levels. It seems the specific die type matters a lot. I recall using Hynix with Cas 13-15-15 above rated speeds, but only reaching around 3000mhz to 3066mhz or a bit higher somewhere. There were some noticeable gains.
I can boot this ICs up to 3600 MHz, not stable tho but I did't really mess with high voltages, there's a chance I can get that frequency to be stable but I don't really see a huge benefit on doing that. I may look into it another day
