I’m looking for some opinions on my current DDR4 tuning. My main goal is gaming performance, especially FPS and 1% lows, not benchmark scores or lowest possible AIDA64 latency.
System:
CPU: Ryzen 7 5700X3D
Motherboard: MSI B550M PRO-VDH
RAM: 32GB (2x16GB) Kingston FURY Beast
Exact DIMM model: KF3600C18D4/16GX
Both sticks are Single Rank
GPU: RX 9070 XT
The RAM is originally rated for DDR4-3600 CL18, with XMP around [18-22-22-39](tel:18-22-22-39) @ 1.35V.
I’m currently running:
3600 MT/s / 1800 FCLK / 1800 UCLK — 1:1:1
Primary timings:
tCL: 16
tRCDWR: 19
tRCDRD: 19
tRP: 19
tRAS: 36
tRC: 55
Secondary/tertiary:
tRRDS: 4
tRRDL: 4
tFAW: 12
tWTRS: 4
tWTRL: 10
tWR: 12
tRFC: 500
tRFC2: 631
tRFC4: 469
tRDRDSCL: 6
tWRWRSCL: 6
tCWL: 14
tRTP: 6
tRDWR: 10
tWRRD: 1
tRDRDSC: 1
tRDRDSD: 4
tRDRDDD: 4
tWRWRSC: 1
tWRWRSD: 6
tWRWRDD: 6
Other settings:
GDM: Enabled
Command Rate: 1T
Power Down: Disabled
BGS: Disabled
BGS Alt: Enabled
DRAM Voltage: 1.40V
VSOC: ~1.025V
FCLK/MCLK/UCLK: 1800/1800/1800
My question is basically:
Does this look like a sensible daily-gaming profile for a 5700X3D, or am I tightening timings/subtimings that don’t really matter in actual games?
I’m specifically interested in real gaming performance, FPS consistency and 1% lows, rather than synthetic benchmark numbers.
Would you personally leave this profile as it is, or would you change any of the timings above for a better balance between performance and stability?
Also interested in whether there are any particular timings here that are unnecessarily aggressive or potentially counterproductive for gaming.
