2023-09-20 03:37:57 +0000 UTCSeems like you've done pretty well here on timings and such, very nice. I think you meant m-die though, b-die is DDR4.

Actually Hardcore Overclocking (Buildzoid)
2023-08-10 20:39:30 +0000 UTCSo theres no safe values or recommended values for 6000mhz vs 8000mhz. Found this on Reddit as recommended values for 6000mhz: ProcOdt = 48Ω ProcCaDs = 30Ω ProcDqDs = 34.3Ω DramDqDs = 34Ω RttNomWr = RZQ/4 (60) RttNomRd = RZQ/4 (60) RttWt = RZQ/2 (120) RttPark = RZQ/5 (48) RttParkDqs = RZQ/5 (48)

2023-08-10 20:37:25 +0000 UTCthey affect signal intergrity and demostrating what they actually do beyond just X value works and Y value doesn't is impossible. Why some values work and some don't is entirely dependent on the motherboard/CPU/RAM/BIOS being used.

2023-08-10 20:33:41 +0000 UTCWas wondering if someone, maybe AHOC, could comment about drive strength and termination values such as ProcODS and Rtt values necessary at every level of ddr overclocking? Thanks
