  • BIOS defaults vs. factory RAM settings F3-10666CL8D-4GBRM A880G+

    I'm in the process of learning about RAM settings, I would appreciate information from G.Skill and experienced system builders before I make any changes.

    My main concern is the difference between the BIOS default RAM settings and the G.Skill-specified settings, and how this might affect RAM life-span, performance, and stability.

    The following is a list of my system components. I use this machine for games, Photoshop, and web design. It's been up and running fine since the very first boot & os install. There have been no BSODs, beeps(the bad kind), etc. All settings in the BIOS are default.

    mobo: Biostar A880G+ (AMD 880G, SB710, AM3)
    bios: American Megatrends v02.68
    mem: G.Skill F3-10666CL8D-4GBRM CL8-8-8-24 1.5v DDR3-1333 (4GB: 2048MB x2)
    cpu: AMD Phenom II X2 555 3.2Ghz
    gpu: EVGA GTX460 SSC
    hdd: Seagate Barracuda 7200.12 500GB SATAII
    psu: Logysis PS575XBK 575watt
    case: Antec VSK-2000

    BIOS, default (Auto) settings report the following:

    Memory CLK: DDR3-1333, DDR3-1333
    CAS Latency(Tcl): 9 CLK, 9 CLK
    RAS/CAS Delay(Trcd): 9 CLK, 9 CLK
    Row Precharge Time(Trp): 9 CLK, 9 CLK
    Min Active RAS(Tras): 24 CLK, 24 CLK
    RAS/RAS Delay(Trrd): 4 CLK, 4 CLK
    Row Cycle(Trc): 33 CLK, 33 CLK
    Command Rate(CR): 1T, 1T

    Is this an appropriate setting, or should I attempt to apply factory RAM settings?

    Thank you in advance for your time

    The default settings are what the mobo loads automatically based on how the BIOS is programmed, by setting the DRAM manually to it's spec timings (8-8-8-24 1.5 volts and Command Rate of 2T, you'll have increased performance......and if all is well and stable, you can try the default of CR at 1T, which will give a little extra performance boost. As far as life span either/or should have no real effect, DRAM normally long outlives the effective life of a computer, It's not unusual to come accross folks using systems made back in the 90's (and you can still find old DDR and SDRAM available new from NewEgg and some other vendors

      Thanks, Tradesman I've been searching for more detailed information about RAM timings, latencies, command rates, etc. Most sites I've found are pretty vague.

      Could you recommend a site that explains the above topics and the statements trp, tras, trfc0, etc?

      if "8-8-8-24 2T" = "CL-tRCD-tRP-tRAS command rate" then I need to find out what these are:
      trtp
      trc
      twr
      trrd
      twtr
      tRFC0,1,2,3

      By the way, my RAM timing options in the bios are:

      DRAM Timing Mode: Auto/DCT0/DCT1/Both
      CAS Latency (CL): Auto/4..12 CLK
      2T Command: Auto/1T/2T
      TRCD: Auto/5..12 CLK
      TRP: Auto/5..12 CLK
      tRTP: Auto/4..7 CLK
      TRAS: Auto/15..30 CLK
      TRC: Auto/11..42 CLK
      tWR: Auto/5..8/10/12 CLK
      TRRD: Auto/4..7 CLK
      tWTR: Auto/4..7 CLK
      tRFC0: Auto/90ns/110ns/160ns/300ns/350ns
      tRFC1: Auto/90ns/110ns/160ns/300ns/350ns
      tRFC2: Auto/90ns/110ns/160ns/300ns/350ns
      tRFC3: Auto/90ns/110ns/160ns/300ns/350ns

            No problem, there's more out there, but that is rather decent
