    Some ddr2 settings
    775 quads and duals at hi fsb on ep-45 ud3

    for information the usual bench records on air for a 8200(c2q) were about 3.6 ghz and 8400(c2q) about 4.1.purely related to cpu multiplier nd fsb.

    The ddr3 aspect makes a difference,, just so long as you think of 500 being around the practical maximum ,u can use your cpu multiplier on.
    Thas 2000mhz fsb.

    check back thru some older p35T and p45T posts

    Hey ugh the corsair memory is it dual or tripple channel ddr3? Also you may need to reset your CMOS after all your testing. Your full system specs in your sig would help greatly so we know wot were dealing with. Guessing wot you have is a disadvantage for all.
    Dual Channel DDR3 1600mhz, I think the only things that are not in my sig are my power supply (thermaltake tr-2 600w) my vga (xfx hd5770)

    Another approach I might take is to search your mother board model and 8 gigs memory.
    Why you think that 8 gigs might be a problem?

    Keep in mind that entering settings that fail and trting a completely new settings won't bring you anyway.
    Identifieyin the problem and adjust settings accordingly one by one is the right way.
    Also stating "I tried those settings" does not help us to help you, be more specific, what settings have yoy tried what have you changed and what made difference for better or worse.
    Yeah I know its kinda frustating that one time works, not changing anything and next time doesnt work.. I'll be posting full settings next time I try OC

    Not necessarily but you may need more dimm voltage and MCH voltage. You might try one stick and see wot happens and then run memtest86. You can get that in the latest overclocking tools thread.

    Also I would look at the link kick provided.

    Also I don't what your trying to acheive or any thing about your cpu or board but, if your trying to get the full 1600 mhz, by my calculation you would need a 500MHz FSB and a memory multiplier of 3.2. Is that possible? I don't know but, what I do now is it will take a lot of testing.

    This is was my 8x500 settings when I was running it (I have since switched to 9.5x400). YMMV with RAM and CPU, especially since you have 8GB. Also, make sure you have a fan on that NB heatsink when getting into the 1.3v and up range for MCH.

    I need to know when do I put more or less, MCH Core MCH Reference, etc on what depends? Just putting differents settings you guys said to me Won't leave me no nowhere

    Well thats why you test with prime95 and use real temp to monitor tour cpu temps. I'm not going to go into details about the procedure right now. But I/we will if your really intrested in Ocing your system. I/we can walk you through the whole process if you wish. It's up to you are you game?

    Im already in the game conners haha Yesterday I spent the afternoon testing a lot, y tried with FSB above 400mhz, can't be much specific now because I tried about 15 diferents settings, all of them without changing load line calibration, and mch core at 1200-1240 mch reference at 0.78 always (like I said, I want to learn when do I need to lower or increase these settings). I tested some settings with memtest86+ (using hiren's boot cd) and learned that low timing isn't always the solution to performance. I've get much more mb/s speed with my original timing (9-9-9-24 @ 1-5) with FSB 450 at 3.2D (ddr's where at 1400mhz more or less) than the full 1600mhz, 8-8-8-20 at 400mhz. I'll be posting this afternoon some full settings that kinda worked for me so you guys help me to set the load line calibration and other advance features, hope I've learn all about it in the process.

    Okay the very rough basics are:
    Higher CPU clock - more vcore
    Higher FSB- higher MCH Core and/or VTT(CPU Termination)
    Higher memory clock - higher MCH Core and/or DRAM Voltage.

    As far as references(CPU or MCH) go, there is no more or less, just right.
    Those two are relative to VTT(percentage) and scale with VTT. You need to find the right vaue by yourself, every system is different. e.g. mine are 0.73 CPU reference and 0.72 MCH reference at 1.2v VTT at 450 MHz with 1.22v VTT.
    I stated references at 1.2v VTT even though VTT is set to 1.22v because this way no one need to do mathe to know what percentage of VTT I use.
    always make reference adjustments at 1.2v VTT then set VTT to what you want it at.
    1. Set VTT to 1.2v
    2. set reverence (CPU or MCH) to desired value.
    3/ set VTT back to its desired value.

    usually I start testing higher FSB with a known stable CPU and memory(as close as possible) frequency. Then higher the CPU clock(ratio). That is why I recomended the 7.5 CPU ratio and LLC(because idle clock is higher too).

    You have stated that in all your testings you had <CH reference at 0.78v was it the most stable value you found?

    thanks for the info! Thats good for a starting point. So I tested a little on 400fsb, I wasn't getting valid settings (by valid I meant good enought for at least booting windows) until I removed one memory stick and left just 4gb in single channel.. I guess 400 or 500 fsb won't be good on 8gb, so I tried this like you said a higher fsb for an known cpu and/or memory frecuency

    Well thats a start. In prime95 do you have under the advanced tab sum(inputs) error checking and round off checking checked? Also while testing disable Load-Line Calibration.

    Wot I do is when I make a chang I start out in P95 using Small FFT's and if it fails righ away or after about 15 min I up the voltage in the previous post where I had the P95 failures. Then test again. If ok after that move onto large FFT's if htey fail see chart apply settings, test again. If Ok move FSB up say 10 - 20 mhz and teast again starting with small FFTs' and so on...G/L
