Quick and Dirty

HWBot y-cruncher 10b Submission Link

First step to memory overclocking is figuring out what type of memory ICs are being used. This will give you a good idea of the voltage and frequency limitations for starters, with extra nuances between different manufacturers. Given that this is also dual-rank memory, extra attention had to be given to secondary timings to avoid failing the y-cruncher 10b benchmark. 3 GB ICs also have their own challenges to deal with.

Here just the basic overclock was performed. After a few failed posts, it turns out more voltage doesn't equal higher frequency. Presumably this was the limit of the CPU IMC; DDR5-6800 for dual rank, as 7200 MT/s was never stable and anything above that simply would not boot. After locking in on 6800 MT/s for this session, the following accrued. Started out at 1.45 V (DRAM), tighten up the primary timings, adjusted the tRFC for the increase in frequency and raising the tREFI value for more "performance" as well. Of course more could have been done with enough hours. However, at a certain point, the secondary and tertiary values adjusted can only be applied to that specific motherboard / CPU combo and the accompanying voltages. Final step was lowering the voltage to 1.35 V and stability testing. A quick and dirty overclock brings this DDR5-6000 memory kit to DDR5-6800 and stable for daily use.
