    Unhappy Re: GA-EP45-UD3P + E8500 + 8gig (4x2g Muskin) ram overclocking help

    Hello everyone. I came to this thread through a google search and wanted the help of Lsdmeasap if possible. I have the R version of the mobo that the OP has (no SLI/X-fire support), but everything else is pretty much the same (1066 Corsair Reaper ram (2X2gig)), E8500 purchased in Jan of this year. I tried the settings that were recommended by Lsdmeasap and could not get the system to boot. The weirder thing, however, is that I could not get it to boot with any combination of multiplier/ram timings, or even lowering the fsb down from 401 to 333. It just refused to boot even to the POST screen. I tried multi's down to 6 which would be under 3GHz, and a whole bunch of stuff in between. I loosened the ram timings to ridiculous values and still nothing. I'm stumped because I am definitely a newb to the OC scene since my last build was a Athlon 64 3200+ 4 years ago. Since then there are a ton of additional variables to change that I just don't understand and this is after reading countless OC threads across the web. I was hoping to be able to simply plug in the values that were suggested and then be able to lower voltages and tighten up timings, but I can't seem to get anywhere. I had been able to get to 3.5GHz by screwing around with just upping the FSB speed keeping everything else on default. That would seem to tell me my CPU is fine and it's something with the ram or more likely all of these weird mobo voltages that I have no clue what they do. Could anyone look at the OP and the recommendations by Lsdmeasap and figure out what the heck could be the problem? I can start a new thread as well if it would be better. Thank you in advance for any help.

    Lsdmeasap currently does not have time, as noted in the sticky thread in this forum.

    List ALL your hardware and fill out the BIOS template and describe what you tried in as much detail as possible. You migh need more MCH Core with 4 RAM sticks but I need more information to tell what's wrong.

    Sorry, I only have 2 ram sticks 2X2gig but they are the Corsair Reaper 1066MHz kit and so should easily handle stock speeds at 2.1v (I even tried 2.2v to see if it was a voltage issue and no luck).

    Basically my hunch is it is a mobo voltage/timing issue with the values:

    CPU Vcore 1.25v [1.35v]
    CPU Termination 1.2v [1.3v]
    CPU PLL 1.5v [1.5v]
    CPU Reference 0.76v [0.823v]
    MCH Core 1.1v [1.38v]
    MCH Reference 0.76v [auto]
    MCH/DRAM Reference 0.9v [auto]
    ICH I/O 1.5v [auto]
    ICH Core 1.1v [auto]

    As I changed virtually all of the multi/FSB/ram timings with no luck. I'm pretty good at deducing problems but this one has me stumped and my guess is it has something to do with those voltages but I don't know where to go (ie higher? lower? combination?)

    I spent about 2 hours today rebooting, changing one setting, rebooting, changing another setting and nothing I did would let it boot. I'm back on stock settings for the time being...

    Bummer on Lsdmeasap not being able to help.

    I need more information to help you. Please fill out a complete a complete template with the settings you used for 3.5 GHz and we'll go from there.

    Also list ALL you hardware!

    My system is:

    Sapphire Radeon HD 4870 512meg (Toxic edition, stock OC)
    Seagate 250gig SATA HD
    SViking case with 120mm fans House between 50-60F during this time of year (it's not a ambient issue!)

    Current settings are back to STOCK but this is what I tried:

    PLEASE HELP!
    EDIT: Does Tweaktown not like Firefox? I typed this up all nice and when I posted it it took out all of my spacing? (NM, found out Noscript was causing the issue. Imagine trying to view that whole list without spaces! Gave me a headache just trying to sort it out.)

    Wanted to also mention something I find very odd. When I look in my bios PC health it says my 12volt line is running at 12.3v. When I use CPUID Hardware Monitor (in Windows) it says my 12v line is 12.48v?!? Can this be right? This is a completely new PSU I bought and Tuniq is not a no-name brand....

    The sensors might be wrong but that does not sound good. Do you ahve a multimeter you could try to measure the voltages of one of the 4 pin PSU connectors with? put one end to a black cable and then emasure the voltage at the yellow and red cable (I don't remember which on is 5V and which one is 12V).

    I do not. Since writing that I did some googling and a lot of people seem to have very wild differences in voltage reporting. I'm just trying to supply all the info so I can get this overclock, but I don't think it's an issue. I've been stable as a rock at stock speeds, even after undervolting my cpu.

    Unstable voltages can be fine at stock (or lower) speeds but a stable voltage from the PSU is extremely important for overclocking.
    Looking at the settings you tried I'm pretty sure that your problem is your PSU. Try to borrow a multimeter (or buy one for 10$) or even better try a differnt, brand name PSU.

    PS: The cause of several people's overclocking problems here in the last couple of days turned out to be the PSU.

    You really don't see any settings I could try in the bios to fix this? I'm still stumped at how I was able to hit 3.5Ghz by just messing around with mostly stock settings, but couldn't even do 2.8Ghz with the recommended voltages and settings when properly setting everything else? That doesn't sound like a psu issue to me.
