Although refreshing a row is an automatic side effect of activating it, there is a minimum time for this to happen, which requires a minimum row access time t RAS delay between an active command opening a row, and the corresponding precharge command closing it. But in the BIOS I only saw 3 numbers that were getting toggled with XMP: DRAM CAS# Latency > 16 DRAM RAS# to CAS# Delay > 16 DRAM RAS$ ACT Time > 36 Jan 14, 2021 · And one more question: After I activated DOCP 3200mhz (loose timings) in BIOS and tested it two times with Hci memory test (one time min coverage 1250%, second time min 1500% - all ok), I transfered lots of data from external HDD to my HDD and installed couple of games. The values range from 4 to 15 with 1 interval. DRAM Voltage - 2. Time Active to Precharge, ACT to PRE . The values range from 4 to 40 with 1 interval. 20000]->[1. We would like to show you a description here but the site won’t allow us. This means that t CL is the only component left of the overall access Oct 28, 2019 · DRAM RAS ACT Time 36 TRC 74 DRAM voltage 1.
