    I would run as a quick test IBT on Standard 5 passes, then use P95 small fft for at least 15 min run withour error the move to large fft and do the same. If you get an error in either one (p95) use the informatioon on P95 errors and retest. Hope my methodology is working well for you. Just out of curosity after you flashed your bios did you load optimized defaults and make changes as necessary to optimized settings then put in your oc settings?

    A couple of things you may already know, or may not. Never have CPU Term higher than your Vcore. Also keep in mind that cpu term voltage auto sets CPU Reference and MCH Reference likewise DRAM Voltage auto sets MCH/DRAM Ref and DRAM Termination. That's why it's important to calibrate them. Such as set CPU term to 1.2 and you should see .760 in CPU Reference and MCH Reference, if not make them .760 then set CPU term back to 1.3. Same with DRAM Voltage Set to 1.8 and MCH/DRAM Ref & term should read .900. If not make them read .900 and change dram voltage to 1.9. Save and reboot.

    Yep. Loaded FFb via USB, loaded optimized defaults and changed to my current settings. Also know about the vtt/ref settings.

    I'll adjust the settings accordingly, though I have tRD on at 8 (from Auto) as per Chike's suggestion.

    When posting setting please post the reference value also for 1.2v VTT, high math gives me a headach :-)
    like this
    MCH Reference.........0.760V...............: [0.863] ; 0.800 @ 1.2v VTT

    A lot of back and forth adjustments yesterday as per Conners post so I left Prime on overnight on small FFT and it failed about 3hrs in at 8k (I've been testing at 1/2hr intervals and it's been fine). Just bumped the vcore and re-doing now at 8k. It seems I may end up with my previous settings.

    Will report back.

    Personally if were me, I wouldn't worry about memory settings outside of proper memory voltage and concentrate on getting it stable on small fft. Therefore I would set Static tRead to auto for now as we are not concerned with it's performance.

    What I would do is and I know it seems like visious circle i'd to start with V core and lower it down till it won't boot then raise it one or two clicks.
    Then set CPU termination to 1.2 and manually set CPU Reference & MCH Reference to .760and all other settings to auto on Motherboard Voltage Control save for Dram voltage and set it @ 1 .9V and set MCH Core to at least 1.26v
    Then I would raise CPU Termination a click or two at a time and test until it's stable in P95 small FFT and maybe add a little to CPU PLL. From there We'll move to Large FFT data.

    I find it hard to believe you need that much Vcore and Cpu Termination on such a small OC. Maybe not but thats just me. I may also depend on how the previous owner abused those voltages Also how are your core temperatures doing? Can you post a screen of Real Temp or something similar?

    Hey Chike can you if you don't mind explain to me how you calculate GFlop scaling, I didn't know you could do that...LOL

    I took me a long time to get mine dialed in to where I was satisified. I don't claim to be an OC guru and maybe someone with more experiance will chime in. I am just going by my personal experiance.

    A couple of other things I would consider is just using 4 gb memory and testing each stick indivually in each slot to see if they were a problem. But that can be a down the road thing if you continue to have problems.

    Also I am going to attach a spread sheet I made up on motherboard settings finder. Its nothing fancy but you can input diffrent settings and see what the suggestings should be... Oh its in Open Office Org but Microsoft off ice should open it not sure about ne thing else... Well never mind I can't upload that file type...

    Yeah if it fails again I'll restart from the beginning. I'm comfortable with upping voltages on all the overclocks I have done on my systems in the past, I had my old overclocked Tualatin at max 1.825v for a decade on virtually 24/7 without issue so that doesn't scare me. This is the first system I've built that uses quiet fans :D

    The previous owner used pretty much the same type of setup (TRUE120) and he upgraded his components on a regular basis so I'd imagine he didn't thrash the chip.

    My temps in Core Temp (Prime95 small FFT)

    Core 0: 35/66
    Core 1: 35/66
    Core 2: 31/61
    Core 3: 37/61 (this core has a stuck sensor at 37)

    Sorry no screenshots. I don't have a spare patch cable to access internet and don't want to keep swapping the cable back and forth

    The temperatures could definitely stand to come down, though it seems to be fine while at load. I'm wondering if lower temps would help for stability and lower voltages with the Quads. I could upgrade the fans and use a better thermal compound but outside of that I'd have to go with a true watercooling setup which I'd rather do without.

    It's very simple, evvery CPU (or CPU model/family) has a "known" floating point operations per clock it can do. The differences between systems/CPUs will be mostly as the result of cache size(3MB/core L3 cache CPUs like E8400 do about 3-5% better than 1.5MB/core CPUs like E7200), a bit as a result of RAM performance, and then system configuration (# of backround processes.

    Idealy Flops should scale liniary with the clock, ,aintaining the flops/cycle ratio.

    Theoretically C2D/C2Q cores can do 4 flops/cycle, which means 24GFlops for E8400 at 3GHz, in reality it will do less.

    So the best we can do is scale our baseline(stock) flops with our OC flops, )Cflops = BLflops * OCfreq / BLfreq.

    Most important is to do all with the same software/version as there may be major differences between software of even software versions.

    Cool Man it's you system, I'd say your temps a doing just fine if thoes are load temps. Those trues are one heck of an air cooler. I'll offer no more advice since you apparently are more knowledgeable in this area. But don't hesitate to ask if you want my opine. Like I say maybe proJim, Wazza300 or LDSmeasap will stop in and offer help. Thanks for listinging to my rant ...lol

    Lol Chike that's greek to me..... So using my settings in post 7 (say 1.26v as above compaired to 1.3v)what would you calcualte my Gflops to be..and use the formuals you describe. I just want to see a visual example to help me understand.. Thanks man!
