    Default LSD, a little GA-EP45C-DS3R overclocking help?

    OK I hope you can help me out again with my EP45C-DS3R! RMA'd the Crucial RAM that was giving me so many headaches, and now I have 2x2 GB of GSkill in this thing running at 4-4-4-12 800MHz. CPU is an e7200.
    Currently, I have it overclocked to 3.163 GHz (FSB= 333 and multi=9.5) and it is perfectly stable. Ran Memtest+ for 8 hours or so without an error, coretemp shows around 35 degrees idle and 57 degrees per core while running prime 95 on both cores 100% load (after 12 hours, also with no errors). All I've really tweaked so far is the Vcore (I think thats at 1.2 or so). MCH and advanced RAM timings are at stock/auto for this.
    The problem is, I'd like to see this thing go just a bit faster, say 3.5 GHz or so, and I can't obviously get the multiplier any higher, but it won't even post for me with FSB at 400. Just goes into a reboot cycle until finally it rolls back the cmos. I've tried increasing the Vcore as high as 1.35 and the MCH to 1.3 or so with no luck. Any idea on where I should start?

    Ok, tried those settings and could not get it to post. Just get a reboot cycle until it lowers bios settings on its own and if it gets into windows after that without me manually adjusting things its actually below stock clock speed. The new memory seems pretty stable and I've heard of people running these GSkills harder than I am so I don't think thats the issue, especially with them basically at stock. Could vdroop be the issue? I set the vCore to what you had listed in my bios, but I've never compared my stable bios values to what the windows based tools show to see how bad my vdroop is. Is the value you listed what I should see in bios or in windows? Or is something else more likely the problem?

    Did you use the highest here >>>
    tWTR..........................................4-6 (May need 8-12)
    tWR............................................6-8 (May need 12-14)

    And do you have Drive Strength profile set? If not set it to 800

    What you see in windows would likely need to be 1.325 or so for 3.6, But I am not for sure with your CPU

    If you set the ram on all highest and it is failing, then it is more then likely CPU voltage.

    Try upping it a bit and also setting this >>>
    CPU Termination…..... 1.200V*.......: <<< 1.34
    CPU PLL…………………....1.500V*.......: <<< 1.56

    your really gonna have to pump the vcore (sometimes more than 1.4V) with the ep45c boards because you'll get a huge cpu droop with this chipset. also try upping the northbridge voltage to around 1.3V

    Did all this, with tWTR @ 12 and tWR @ 14, even cranked vCore to about 1.4 and northbridge to 1.3 as BongWizard suggested (thats obviosly the voltage shown in bios) and still no post. Perhaps it still needs to be higher, but how high can I go without worrying about burning up my CPU? Also, I'm not sure what a Drive Strength Profile is or where to find it. As always, thanks for the replies!

    What do you have the MCH latch set to?

    Driving strength profiles may not be in your BIOS unless you are using the latest. They will be in The advanced memory timings page. So if you have everything for the ram on one page then you either have a older BIOS or you BIOS will not have them as of yet.

    Here is a example of where you will see them in the latest BIOS >>>

    MCH Latch = 333. Honestly didn't try 400 because it seemed that was less likely to work. i do have F4 bios since it went non-beta, so I think the driving strength profile may be there, I didn't pay much attention to the changes I didn't recognize straight away yet. Thanks for the pics, I'll check to see if I have that setting when I get home tonight.

    Just got a chance to try. F4 bios for this board does have the driving strength profile options, so I set that to 800, have Vcore cranked all the way to 1.45 (in bios) and it still won't post. Have I maybe gotten a weak chip or do I need to play with other settings, like loosening the main RAM timings? Everyone seems to suggest Vcore but I'm afraid to go higher, especially for regular use.
