It turns out Sciencemark 2.0 (www.sciencemark.org) and LMBench produce nearly identical memory latency results. Here are all of the results I have gathered from some of my computers thus far. Also, memory timings stated like "2-2-2-5" are CAS, T(RP), T(RCD), and T(RAS). LM BENCH: 2.4GHz AthlonXP | Epox 8RDA Board | Nforce 2 chipset | Single Channel DDR 100fsb CL2 | 123.7ns 133fsb CL2.5 | 114.7ns 150fsb CL2.5 | 102.3ns 200fsb CL2.5 | 73.0ns 220fsb CL2.5 | 62.2ns ------------------------------------------------------------------------- 2.4GHz AthlonXP | Epox 8RDA Board | Nforce 2 chipset | Dual Channel DDR 220fsb CL3.0 | 66.2ns 133fsb CL2.5 | 107.3ns ------------------------------------------------------------------------- ------------------------------------------------------------------------- ScienceMark 2.0 (Windows XP/2k, etc) 2.4GHz AthlonXP | Epox 8RDA Board | Nforce 2 chipset | Single Channel DDR 100fsb 2-2-2-5 = 121.79ns 133fsb 2-2-2-5 = 113.31ns 200fsb 3-3-3-7 = 74.49ns 220fsb 3-4-4-8 = 68.73ns ------------------------------------------------------------------------- 2.4GHz AthlonXP | Epox 8RDA Board | Nforce 2 chipset | Dual Channel DDR 100fsb 2-2-2-5 = 123.46ns 133fsb 2-2-2-5 = 106.69ns 200fsb 3-3-3-7 = 74.41ns 220fsb 3-4-4-8 = 68.47ns ------------------------------------------------------------------------- 2.5GHz AthlonXP | Epox 8K5a2 Board | VIA KT333 chipset | Single Channel DDR 200fsb 2.5-3-3-6 = 94.54ns ------------------------------------------------------------------------- 2.0GHz AthlonXP | Asus A7V266-E | VIA KT266a chipset | Single Channel DDR 133fsb (no idea on timings) = 110.76ns ------------------------------------------------------------------------- 1.6GHz AthlonXP | Abit KT7a Board | VIA KT133a chipset | Regular SDRAM 133fsb 2-2-2-5 = 128.20ns ------------------------------------------------------------------------- Celeron 566@1004MHz | Abit BE6-2 Board | Intel 440BX chipset | Regular SDRAM 118fsb (2-2-2-something) = 89.51ns
