    The SuperPi 1M was disappointing. Didn't break 11s.


    The 3dMark06 was also disappointing. My best score to date was at 3.6GHz with my GPU overclocked, 15191. This test was at the same GPU settings as then but at 4.25GHz.
    The Everst memory test cam out nice, though.

    Now if I can just get to 4.5GHz again... its so frustrating that I was able to get there once, hit 10.5s on SuperPi 1M, and not get back....

    I am starting to think that maybe my PSU might be the reason why I can't get 500x9. I only have a 500w PSU and I read that my CPU might require as much as 130w at load and that the EP45-UD3P needs something close to 375w; add in my 9800GT and I am well over 500w. Any comments?

    Out of curiosity, I changed to 473x9 (4250MHz) and ran a SuperPi 1M... it was a hair slower, 11.197s.


    However, I made the change without changing any other settings, just FSB Clock and multi. That made me think maybe that is a way I can walk my way up to 500x9... or beyond.

    489x9, better than 500x8.5 in SuperPi for sure, but then its 4.4GHz

    That's 10.832s, still not beat my fluke best.

    OMG I got 500x9 to boot.... woooot. I did beat my SuperPi time, by .01s!!



    I am not sure if I want to test for stability tonight though... I think that should wait till I am going to be home for the first several hours to monitor it. So, I will save the profile and work some more on it this weekend.

    Oh, you can't tell, but MCH Ref is set at .72. And LLC is ON, not sure if that is a good idea or not.

    Yep, nothing wrong with your PSU, as long as it's a good brand/OEM.

    I had a go on this PSU calculator, and with 15% capacitor aging, at 100% load I got you to 369W needed. That includes your CPU which is sucking up a massive 122W at that speed and voltage. 500W should be cool. eXtreme Outer Vision - eXtreme tools for computer enthusiasts

    At 80% efficiency, your PSU should be drawing about 443W from the wall. You might want in the future to upgrade to an 85%+ certified unit, which drops power consumption to 425W, but it's not much difference unless you're on the machine 24/7.

    I am going to upgrade to a 800 - 1000w PSU sometime this year.. but for now, I think I agree with you, I am in the clear.

    I got 512x9 (4608) to Boot. No stress test yet. LLC on, pushed 1.4125v, vterm 1.34v, set MCH Ref to .70, MCH Core 1.34v...


    10.328s SuperPi... getting lower... muwahhaha.

    A lightning storm moved in right after I logged on... so I did the SuperPi then logged off, didn't do an Everest Memory Test.

    Sorry to Necro this thread, but I am thinking about my PSU again.

    Here's the thing. At 4.005GHz Everest shows me drawing 37.81 amps to CPU. My PSU is rated at around 36 amps combined on the two 12v Rails. However, at this speed, and 4.25GHz, I am able to stay stable; perhaps the 36 amps is mfg recommedation and really I have a little headroom...

    So, when I try to go higher 4.5 and 4.608, 550 x 8 and 533x8, I can boot in to windows, but when I try to run tests I BSOD. This is no matter what I do. Worth noting, though, that temps are way under TJ max for these speeds.

    Furthermore, I can not get any build higher than those to boot to windows. 515x9, no go. 533x9 no go. I have tried a bzillion voltage combinations, going as high as 1.55vCore, 1.73PLL, 1.42 MCH Core, 1.42 CPU Term, 1.57 I/O , 1.3 I/O Core, loosened timings, set timings to AUTO... I have gone down to 4GB RAM... I have modified Ref's, including DRAM Refs... you name it, I have probably tried it, and no boot.

    Sometimes I get close, but hang at the Verifying DMI Data Pool.... Sometimes I get past this and get to choose to log into Windows in Safe Mode, Normal Mode, etc... However, when I choose any of these options I always BSOD with a Stop Error (I think), as if now a load is being put on the CPU causing the amp draw to ramp up. When I revert settings and log into windows I get the "Hardware Failure" message that we have all learned to kind of ignore...

    The only thing that I can think of is that my PSU can't handle the additional load on the 12v Rails...

    So, anyone wanna validate my suspicions? I mean, if it's the case that my hunch is true, no biggie. Just means that I have to wait to buy a better PSU before I can try for 4.8GHz and higher. If not, then I am at a loss why I can't get these higher clocks when some people that I know who have the same MoBo/CPU/RAM combo as I do who can. Shoot, one of my friends can run 4.8GHz (on air) at 1.47vCore, 1.57 PLL, 1.36 vTerm, 1.36 MCH Core with no Ref mods... one difference between his rig and mine is that he has a 600W PSU that can provide a combined 44 amps at spec, with headroom to spare most likely.

    I still think your PSU is fine.

    Ignore the fictional power and amperage readings Everest shows. You'll need equipment a little more expensive to correctly assess the amount of current being drawn. Their's certainly no0 way you're drawing 37A. If that were all on the 12V rail, you'd be using 444W. Not likely at all while merely running Prime/IBT. If you were also fully loading the GPU, then I could believe it was somewhere close to that but still less.
