    EXACTLY what I am wondering. Doing some tests, I am finding that some much lower values than recommended from the charts gets my rig more stable.


    Core i7 920 D0 B-batch (4.1) (Kinda Stable?) | DFI X58 T3eH8 (Fed up with its' issues, may get a new board soon) | Patriot 1600 (9-9-9-24) (for now) | XFX HD 4890 (971/1065) (for now) |
    80GB X25-m G2 | WD 640GB | PCP&C 750 | Dell 2408 LCD | NEC 1970GX LCD | Win7 Pro | CoolerMaster ATCS 840 {Modded to reverse-ATX, WC'ing internal}
    CPU Loop: MCP655 > HK 3.0 LT > ST 320 (3x Scythe G's) > ST Res >Pump
    GPU Loop: MCP655 > MCW-60 > PA160 (1x YL D12SH) > ST Res > BIP 220 (2x YL D12SH) >Pump

    Heh, great tip


    According to some tests and my own findings, for 45nm chips it's about 55-57% BUT it's my not for 100% sure...

    Here's an example using E8200 on DFI P35 LanParty (link)

    4200MHz - 8x525MHz, VTT 1.2V, VCORE 1,45V
    GTL - AUTO - restart during OS load
    GTL - 85/85/85 - restart during OS load
    GTL - 76/75/76 - SuperPI 32M - error just after start
    GTL - 73/72/73 - SuperPI 32M - error after loop1
    GTL - 70/69/70 - SuperPI 32M - calculation done. Goin' further...

    4304MHz - 8x538MHz, VTT 1.2V, VCORE 1,45V
    GTL - 70/69/70 - SuperPI 32M - error jus after start
    GTL - 69/68/69 - SuperPI 32M - error jus after start
    GTL - 64/63/64 - SuperPI 32M - error after loop8
    GTL - 62/61/62 - SuperPI 32M - error after loop12
    GTL - 60/59/60 - SuperPI 32M - calculation done

    I used it just for orientation to have good "start point"... then found stability and gave up OCing

    i used faster method
    i used memtest test 5
    i set ram aggressive lots of settings i averaged 200 errors then i found settin with -20 errors n tweeked
    every cpu n every board n ram react different
    dual core cpus are verry forgiving on bad setting not quads
