    Okay yeah it must be that, and that I was thrown off by MIT telling me it was running 2t command rate and everest/memtweaker both showing 1t when left at auto. Took me a while to realize that MIT screen is displaying not only an incorrect qpi-rate, but also wrong cmd-rate.

    I'm still kind of struggling why I can run these 1333 dimms up to 1600 with the main timings at 9-9-9-22 and subtimings at 1066 level from the spd without seeing much change in bandwidth over way looser auto setting.

    I'm guessing the IMC is not able to fill the bandwidth of the mem fully, and because it's not hammering the mem I'm getting away with too tight settings... (and not seeing any improvement going from(in bios order): cas-trcd-trp-tras-trc-trrd-twtr-twr-twtp-twl-trfc-trtp-tfaw-cmd-trd

    to
    9-9-9-22-27-4-4- 8-19- 7- 78- 4-16-1- 12

    anyhow, I've decided to get an other cpu (i860) for the board and see what happens then...

    You can ignore any settings you see on the left side of the BIOS, those are not what Auto/current is using.

    If you need help or suggestions with your settings please fill out a template from my signature with your current full settings and I will advise back

    Okay here's my template, have a look maybe you can see something I missed from it,
    my main questions are:
    - how to get lower latency on the mem, I'm struggling the get sub 60ns(everest)
    - how to get to 22x bclock, I've tried upping vcore and vtt several steps, but it did not make much difference, windows will boot, but prime fails in a bsod (ususally 101 or 124),.

    Since I took several steps onn vcore and vtt I think maybe I should tweak some other voltage, so I tried the PLL one step up and on step down from default, but that's not it... maybe it still needs more vcore, but since I'm on air I don't want to go beyond 1.45v witch seems quite a step up for 200mhz already.

    Maybe this will help...

    BSOD Error codes and what they mean:
    0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
    0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
    0X00000101 << Not enough Vcore Voltage

    As for your CPU multi, what is the max multi you can set anyway?

    Your QPI looks too high, set that manually to x36 or whatever your lower multi is

    Can you give me a link to your memory before I advise

    For now, you may just be needing more QPI/Vtt, Intel has updated the max for this to 1.4 so you have a bit of room to go anyway. I't try 1.25-1.34 and see if that helps, if not do pay attention to your BSOD's and see the above notes on them

    thank you, yeah I knew error codes, but after like going 5 points up on each vcore and vtt, you start thinking maybe it's something else.

    Max cpu multi is 48x and in theory should go even higher. I've left QPI at auto, resulting in 24x (bios will show 48x) or 22x as soon as I go over 190bclk, can set 12,14,16,18,20,22 and 24x.

    I don't think it's too high because it's working ;) and changing the cpu multi won't change the QPI frequency, but will try at lowest multi just to be sure.

    The memories are OCZ3G1333LV2G/4GK nothing special...

    I've tried upping vcore and vtt up to 1.45/1.40 in steps, but it did not help... maybe it needs more V still, but somehow I think 0.18v up on both should have been enough for an other multi... I don't care much for intel limits ;) where would we be if we all obeyed them... but maybe I've reached the max of my own limits on air, just can't cool it down enough to give it more V...


    As for the timings, you seem to agree that what I've set now and seems to be working is insanely tight for these mem's ... but hey it's working... so...? it's giving me the feeling some of the settings make no difference at all, or maybe something else is going on. Can't imagine the sticks will run with these timings if I pop in a lynfield...

    I hear ya, and you know what sometimes they are wrong too. Like sometimes 124 can mean you need more Vcore instead of Vtt, and also sometimes they actually do mean you need less (Normally when this happens it is less Vtt)

    Thanks, if you need CPU multi 22 then all you have to do is manually set it and disable turbo boost. I have to say though, even CPU multi's can sometimes be terrible to use, not always though, but generally they take more voltage and are less stable.

    QPI, set 18 (36), you are using 8.8Gt/s now which is 22 (44), and it's too much. You need to keep the QPI ideally under 8.0Gt/s to keep it stable, yes it will work higher but it will cause you issues and you wont know what is doing it, like now.

    Try these settings and see how you get along, of course you will need to tinker around a bit

    Okay!

    I'm back and I'm at 4.4GHz! You tip "sometimes 124 can mean you need more Vcore instead" helped out indeed...

    The more I upped the VTT towards 1.4v the sooner the 124's started to happen, so I put VTT back where it was (1.23v), that was enough for 200fsb anyhow it seemed.

    Rule nr1 kept ringing in the back of my head, "Vcore nevermind the limits, as long as you keep it cool enough just give it what it needs..." and so I did... at first I thought 1.4v should be enough but it wasn't... so I ended up at 1.45v ... peak temp only 2c up(at 83C) from the previous 4.2GHz/1.33V OC ...

    I tested some with the QPI but in the end I just left it at 44x, it seemed fine there anyway...

    I did manage to tighten-up mem some more to 800mhz c8-8-8-19 trfc:78, trd:10 and I'm still tweaking. Still 60.7 ns but looking at the overclark thread at xs I'm getting descent mem scores, so I should be content I guess...

    So... thanks for your help and the good discussion. I'm satisfied now ...
    I'll post my final template for reference later on, after a play with the timings some more.

    Nice to see you got things going!!

    Ya I wish I knew what caused the BSOD codes to be "other things" sometimes, but at least we know so when needed we can try to remember.

    I sometimes also see 124 when memory voltage is too high too, but not often.

    Good luck with the continued tweaking, let us know what you settle in for
