    About my temp problem, I have to confess that it's because of my fault. I said earlier I was sure that the heatsink was installed properly, but in fact, it wasn't. I found that I can press all 4 pins even further and they're now very hard/stiff.

    I then fired up Prime and now with 25c ambient my CPU temp is within 60c, as oppose to earlier, where it's around 72c

    Anyway, back to my stability issue, I've just tried using the config you suggested kimboy (except Dram Voltage, which is 2.1 in my case), but at one click lower Vcore (1.4xxx) because my CPU is stable at 3.36 at that voltage, and bump up PLL from 1.5 to 1.57, to see if I can get 3.4 stable.

    Unfortunately it still failed at Prime.

    Now I set it at 6*450 (2.7Ghz), to ensure that it's not the ram that causes this.

    If it can make it through Prime, I will now focus on the CPU.

    I have some questions for you.
    - If it appears to me that RAM doesn't cause this, but it's the CPU, does increasing MCH Core help maintaining CPU stability (it should be for the Dimm, right?)
    - If MCH C doesn't help, then I should focus on VCore, PLL and VTT, right?
    - If I have 2 stable settings I could use, which one you think should give me best performance:
    1. 8*420 (3360) @4-4-4-12
    2. 7.5*450 (3375) @5-5-5-15
    (while typing, I don't even know if 7.5 is available)

    I think that 15 Mhz difference shouldn't matter, but the bus speed does. IMO the 2nd scenario should give me better performance, despite its slower ram timing, right?

    Thanks

    Just while im looking at the thread.

    standard intel cpu cooler should give max load temps8-10 degrees higher than a good aftermarket cooler when the cpu is overclocked,approx)

    If you dont see a .5 multiplier option in bios,the cpu doesnt have it.
    my cpu is either 6 or 7 multiplier,im assuming q8400 is 7 or 8,i could check but im too lazy.

    MCH or memory control hub voltage.. well its not simply for memory,Its more what voltage the interface between the memory and cpu needs at any given cpu /memory speed.
    If cpu is held "relaxed" tho you will only have 2 main adjustable voltages to worry about. like if cpu is working at 3000mhz at 1v and memory is working as hi as you can get it stable say 1000mhz with 2.0 v and mch core is at 1.3V its unlikely u will be able to increase cpu speed to say 3.7ghz just by upping cpu core V.
    I personally have found the simplest way to check what my memory will spin up to is

    hold cpu at near standard speed with standard 333mhz fsb /cpu ref and use a multiplier to test the memory.
    you can slowly increase the fsb this also increases cpu speed but jumping to a 2.66 from 2.4 may be too much initially.
    If everythings good at say 400 fsb you can drop down the multiplier on the cpu and increase the memory speed by increasing the fsb speed..slowly.

    in this sort of testing you should really only have to vary the dram voltge and mch voltage.

    Eventually you will get to know what the memory will clock to under lots of different settings and where its limit is..mine is in and around 1000mhz.
    In other words its not 8600 or 1066mhz memory.
    Some 800mhz memory will clock to 1066 tho

    I cant get it to run at 1066mhz even if the cpu is running below stock speed.
    I do know it will run 1000mhz without going crazy on voltages and 1060mhz is its limit if i do go crazy on voltages and use 6-6-6-18 timings,
    sooo 1000 or a little below if i really want to throttle back is about as good as Im going to get with it on any cpu.
    Surely if i can get 1060 i can get 1066.maybe at the risk of burning out the mem or crrupting OS..not worth it.

    Since I know that, its much easier to adjust max cpu/fsb speed and memory timings.

    Thanks for the tip, kick.

    From yesterday experimental, I know that:
    - my RAM is OK at 450FSB
    - my CPU won't be stable at 3.36 unless Vcore is 1.344, as I tried reducing Vcore and increasing PLL to 1.57, but it couldn't help it.
    - my CPU won't be stable at 3.36 if CPU Termination is lower than 1.3, which is strange since I saw many people with this CPU pushing it even further with 1.2x VTT.

    Between 8*420 and 7.5*450 (yes, 7.5 is available), I choose the latter, even if I have to go with more relaxed ram speed (5-5-5-15).

    Now if I can get another 132Mhz out of it, it'd be great, but if it takes something like 1.4VID, 1.57PLL, and 1.3 MCH to get that extra speed, I'd rather stay here.

    @kimboy11
    EXCELLENT!!!

    I'll be out for several hours, and I'll post back later tonight.
    I assume that you still want to try for a 3.60GHz overclock.
    Save your current settings as an additional bios profile.

    **EDIT** Please post your 3.40GHz bios template.

    @kimboy11
    Right now your memory settings are far from optimal. We'll take care of this after you've reached your final overclock.
    You might want to perform some gaming benchmarks (FPS) now so that you can compare benchmark results with higher overclocks.
    You'll need to watch your core temperatures closely as you overclock further.
    For 3.60GHz, set:

    CPU Host Frequency (Mhz) --------------: [450]

    System Memory Multiplier -------------- : [2.00D] <-- leave at current setting
    Memory Frequency (Mhz) -------------- : [900] <-- this is set by your bios (2.00D x 450MHz = ddr2-900 speed)

    Standard Timing Control <-- these will be tweaked at the end of overclocking
    CAS Latency Time -------- 5 ---------- : [5]
    tRCD --------------------- 5 ---------- : [5]
    tRP ---------------------- 5 ---------- : [5]
    tRAS -------------------- 18 --------- : [15]

    Advanced Timing Control <-- these will be tweaked at the end of overclocking
    Driving Strength ---------------------- : [1066] <-- set this for memory channels A and B, this was previously set to AUTO

    Channel A
    Static tRead Value --------------------- : [9] <-- this is necessary when using 2.00D system memory multiplier and 450MHz
    Channel B
    Static tRead Value --------------------- : [9] <-- this is necessary when using 2.00D system memory multiplier and 450MHz

    Motherboard Voltage Control
    CPU
    Voltage Types------------ Normal -------- Current -----
    Load-Line Calibration ------------------ : [Disabled]
    CPU Vcore --------------- 1..2875 ---- : [1.35625V] <--- 1 step higher than previous setting, 1.36250 might be needed
    CPU Termination --------- 1.200V* ----- : [1.200V] <--- leave it for now, if stress testing fails fairly quickly, increase to 1.22 - 1.26 one step at a time and retest

    Post the full 3.60GHz bios settings and screen-shots after your tests.
    Let us know maximum cpu core temperatures and details about any worker thread errors, including how long the test ran and what the error message was.

    Go for the gusto!!

    Well i hav finally ran into sum problems.

    CPU Vcore --------------- 1..2875 ---- : [1.35625V] <--- 1 step higher than previous setting, 1.36250 might be needed
    CPU Termination --------- 1.200V* ----- : [1.200V]

    i've changed all the settings to what you hav mentioned and tried cpu vcore from 1.35625 and 1.3625 and changing the cpu termination for each cpu vcore setting from 1.200-1.260V. When i turn on my computer it double boots and it beeps continuously. the beeps r in short intervals which i think it means not enuf voltage or something. help??

    oh the computer double boots now even after using the 3.40Ghz bios settings which it never use to.

    Edit* the computer only double boots when i reset the Cmos from 3.60Ghz bios setting. at 3.40 its ok now.

    Default Re: GA-EP45-UD3R/UD3 Overclocking for first time

    Could be the ram, try one step up tRD (Static tRead Value) and CAS 6. To eliminate other problems set one tick lower CPU Ratio.
