PLLs can be used to provide a slower clock frequency to the core of a DRAM, while the interface operates at a higher clock frequency. RAM runs dual channel (two channels) therefore each channel is 50% therefore that why 1067 MHz comes from. ) Use the lshw command with the memory class: $ sudo lshw -C memory # Some things about firmware and caches *-memory description: System Memory DRAM. The 2nd overclock profile is a to try to get the timings as tight as possible with memory frequency a secondary. In this article, we will be using a large set of benchmarks across both Intel and AMD platforms to show that RAM running at higher frequency at the cost of increased timings gives little to no real-world performance improvements. In an ideal world, RAM would have high frequencies and low timings. Okay, before everyone tells me to use the search function, I understand that the true RAM frequency is DRAM Frequency x2 on CPU-Z. 0 MHz witch would amount to only 800 MHz being a DDR3 Increasing DRAM frequency in BIOS.
