Your DRAM has multiple SPD timing profiles for different clock speeds. The ones for the slower clock speeds have lower latency. When you switch the multiplier with the settings in "auto," the motherboard is switching to the lower latency profile. You can look at your memory's timing tables using the SPD tab of CPU-Z.Crayon Shin Chan wrote:All DRAM timing values were set to "auto". I tried setting CAS, RAS to CAS, RAS PRE and ACT to 9-9-9-24 (the motherboard actually runs them faster than the SPD recommends, so 9-9-9-24 is actually a step backwards, plus I set the speed to 1100MHz).
