Use this RAM latency calculator to learn how RAM works, how to calculate its latency, and the formula behind the calculator. Instead, any set value of tWR gets fed into tWRPRE (which does exist). Rules for tras, trc related to other timings and trfci being that high causing heat related instabilities. ROG MAXIMUS Z690 FORMULA. B. It's recommended to go off addition of tRTP because it can go lower than tWR. The maximum value is bounded by the limitations imposed by refresh. I think tWR hard walls at 8 or 6, though it's recommended not to go below 8. For optimal performance, use the lowest value you can, according to the tRC = tRAS + tRP formula. 0 Desktop Compter Memory CL34 32GB (2 x 16GB) DDR5 7000 (PC5 56000) RGB Model #: ShenCe DDR5 16Gx2 7000 $ 169 . 05. 8 GHz = 30. 2 Gen 2x2 front-panel connector, Dual Thunderbolt™ 4, PCIe ® 5. tfaw，理应为trrdsX4即32，但，d5似乎不必遵循这条规则，可以设置为24，最小不能小于16 到底是32效能好还是更低效能好，不知 Oct 25, 2021 · Example: tCL at DDR5-5600 DDR5-5600 has an actual frequency of 2.

Even values for tWRWR SCL and tRDRD SCL can improve system stability. Have seen a few posts on here where certain members are stating that peoples timings do not make sense because it should be for example tRAS= tRCD (RD) + tRTP (this is just an example it may be wrong). Between 16-20 should be good. Information really isn't that consolidated for DDR5, so I'm just struggling to get values that are safe 24/7. Then try tRTP at 20, it should be fine, if not try a notch higher.
