Dear Overclocking community,
I recently ran into game performance issues that led me into investigations of my memory settings. As I have very little knowledge about this topic I have found a guide from Buildzoid that seems to address relevant settings in this video.
I would like to understand if the following settings are appropriate and whether they can be considered as stable for my current setup:
AMD Ryzen 5 7600
64GB Corsair CMK64GX5M2B6400C32 DDR5 (2x32GB)
ASRock B650 Phantom Gaming Lightning
I am using the following voltages and timings to successfully boot into a 6000 MT/s configuration:
FCLK: 2000
UCLK DIV1 Mode: UCLK=MEMCLK
VDDIO (VDDIO_MEM_S3): 1.35
DRAM VDD Voltage: 1.35
DRAM VDDQ Voltage: 1.35
DRAM VPP Voltage: 1.8
SoC/Uncore OC Mode: Auto
SoC Voltage (VDDCR_SOC): 1.25
VDDP Voltage: Auto
VDD Misc Voltage: Auto
VDDG CCD Voltage: Auto
VDDG IOD Voltage: Auto
Power Down Enable: Disabled
tCL: 32
tRCD: 40
tRP: 40
tRAS: 126
tRC: 68
tWR: 48
tRFC1: 500
tRFC2: 400
tRFCSb: 300
tRTP: 12
tRRD_L: 8
tRRD_S: 4
tFAW: 20
tWTR_L: 16
tWTR_S: 6
tRDRDSCL: 4
tRDRDSC: 1
tRDRDSD: AUTO = 9
tRDRDDD: AUTO = 9
tWRWRSCL: 4
tWRWRSC: 1
tWRWRSD: AUTO = 9
tWRWRDD: AUTO = 9
tWRRD: 2
tRDWR: 16
When booting these settings the BIOS/UEFI reads the chips' manufacturer (=Hynix) and the desired speed of 6000 MT/s. Booting into Arch or Windows works fine; the desired speed is readable with dmidecode/ Task Manager.
Prime95 runs blended tests fine on all cores for hours. Prime95 ran into issues in 5/6 tests within 10 minutes using the XMP/EXPO which comes with the memory kit.
I would like to understand whether my RAM has any hardware difficulties. I am therefore striving towards stability instead of speeds.
Any feedback is GREATLY appreciated.
