    G'day. While back I was playing with Typhoon Burner and changed some timings. After finding that the new timings did not help my overclock, I reverted to a SPD backup I saved with Typhoon.
    Short story long, I would like to check to make sure the timings are right.
    So please help if you have the DDR2 sticks mentioned, or know where I can get the detailed info.

    DDR2 sticks: Corsair CM2X1024-6400 (XMS6405v5.1 [TWIN2X2048-64002GB kit]

    I know the basic timings of 5-5-5-18-2 at 1.8v and 5-5-5-12-2 at 1.9v.
    What I would like to know is these timings: tRC, tRFC, tRDD, tWR, tWTR, tRTP.

    At this time I am using the backup SPD data:
    tRC = 22
    tRFC = 42
    tRRD = 3
    tWR = 6
    tWRT = 3
    tRTP = 3

    But found a SPD file for the CM2X1024-6400 over here: http://softmode.techpowerup.com/spddb/details.php?id=4.
    And am using SPDtool v0.62 found here: http://infodownloader.blogspot.com/2007/10/spdtool-062.html.
    SPD data:
    tRC = 22
    tRFC = 30
    tRRD = 3
    tWR = 6
    tWRT = 3
    tRTP = 3

    The timing to note is tRFC (bold).
    Please help.

    Update: Never mind. I always do a quick search when I have a problem. And then post the question. Then do a more detailed search. lol :bang:, I need to change this tactic.
    Found the answer over at asktheramguy.com: http://www.asktheramguy.com/v3/showthread.php?t=63270&highlight=CM2X1024-6400+trfc.
    So the tRFC needs to be 42. Sorry fellas.
