Getting Close to Final RAM Settings

By 1 Min Read

New to overclocking, getting totally obsessed after watching a bunch of BuildZoid videos.

I think I am getting close to where I want the RAM timings at for my daily gaming build. Wondering if anyone has suggestions of where I could safely (stability wise) tighten things. I've tested the stability out to 13 hours on Karhu and supplemented with y-Cruncher and OCCT.

Here is my tuning spreadsheet:(https://docs.google.com/spreadsheets/d/1f3WDfdRUVaPIXWr7ytSrz5vo9lGGcOK5aPXobGY4VOQ/edit?usp=sharing). Disregard the CPU notes, I am going to redo those with per core undervolts then see how far I can push the clocks after I am done with the RAM. GPU is basically locked in, although I just improved the cooling so maybe I can get a little bit more out of it.

Some things of note:

  1. PHYRDLs match

  2. DIMMs run hot on y-Cruncher at like 67 deg celsius but system is stabled even with max tREFI

  3. VDDIO won't go lower than 1.38V, I tested extensively

  4. tRCD won't go below 39, instantly unstable

  5. I was getting a ton of PCIe Error Counters until I forced the main PCIe slot to Gen4

  6. RAM kit is 2×48 6600 CL32 Corsair Dominator Titanium RGB (Hynix M-Die)

  7. ReBAR is enabled

Thanks in advance.
