    Good luck, I know it can be a bit difficult to get things working perfect!

    hah, well right you are. I didn't think I would get stuck so soon...

    I managed to get up to 3,5 ghz using the following settings:

    Robust Graphics Booster - AUTO
    CPU Clock Ratio - 9x (+fine clock 0,5 for e8500)
    CPU Host Clock Control - Enabled
    xCPU Host Frequency (MHz) - 369
    PCI Express Frequency -100
    CIA 2 - DISABLED
    System Memory Multiplier (SPD) 3.33 B= mem freq 1228mhz
    DRAM timing Selectable (SPD) Manual

    Performance Enhance - STANDARD


    xCAS Latency Time - 7
    xDRAM RAS# to CAS# Delay - 7
    xDRAM RAS# tPrecharge - 7
    xPrecharge Delay (tRAS) - 20


    ********Advanced Timing Control*********
    xACT to ACT Delay (tRRD) - 4

    xRank Write to Read Delay - 5

    xWrite to Precharge Delay - 10

    xRefresh to ACT Delay - 60
    xRead to Precharge Delay - 6


    xStatic tREAD Value -7

    xStatic tREAD Phase Adjust - 0 AUTO

    xCommand Rate (CMD) - 2

    ********System Voltage Not Optimized********
    System voltage Control - MANUAL
    DDR3 Overvoltage Control - +0.30 (=1.840 under PC health)
    PCI-E Overvoltage Control - NORMAL
    FSB Overvoltage Control - + 0.1
    (G)MCH Overvoltage Control [+0.225V]
    Loadline Calibration - AUTO
    CPU Voltage Control - NORMAL
    Normal CPU VCore - 1.23500V (two notches up from default)

    Everything works fine like this.
    But once I try to get to for example 3,8 ghz, by going to a fsb of 400
    (which takes my mem to its native 1333mhz on 3.33 by the way) and overvolt to 1.30Volt windows fails to boot.

    Do you have any idea where this goes wrong?
    (what do I need to do with the loadline cal? And is 3.33B on 400FSB still a good idea?)

    Thanks
    Bram

    You may need more then 1.3 for your CPU Voltage, I would say set to 1.35 or so and then lower later.

    You should also use 402 and not 400 exactly. And until you get it running I would use Static tRead of 8

    You can enable loadline or put in auto, what it does is try to stabilize/lessen vdrop and vdroop. So that what you set in the BIOS for Vcore is closer to what you actually get in windows. I would say leave it disabled, and just up the voltage to the actual amount you need. Which as of now is more then 1.3 for sure, as you are likely only getting 1.28 or so with that

    Check with CPU-z and see how much vdrop you have from any other voltage setting. Then you will have a better guess on what you set will actually give you in windows. You may need 1.325-1.34 actual to get 3.8, but not likely all that much. But for sure at least 1.3-1.32 actual

    woa, that was fast.

    It worked well too...
    I put 1.33125V in my BIOS, CPU-Z shows a voltage of 1.328, I left the loadline calibration on Auto. I put the FSB to 401, and changed the SPD to 3.20B which gives a 1260mhz memspeed. The 3.33D option would result in 1337mhz, that might be shaky right? Tread at 8 and a clockspeed of 3,81ghz.

    Cool bananas, first time overclock!

    Hah,

    Once I thought I got the hang of it I tried to push it to 4ghz, using a 423 FSB and 1.345V on the chip. According to Cpu-z that results in a 1.34V in windows. Let's see how this config holds up.

    Once again, thanks for all the help

    1337 would be fine if you would like to use it, and more likely you just may need to loosen ram timings a bit at some point for stability

    Nice to see you are getting somewhere! Glad I could help you along, post back anytime
