Was 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

buildzoid

they 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.

So 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)

Seems like you've done pretty well here on timings and such, very nice. I think you meant m-die though, b-die is DDR4.
