    This is the highest 32M-stable speed I managed on CL7-7-7-14 1T, VDIMM is 2.04V:

    Now I'm working on CL8-8-8-24 1T, but I can't even get it 32M-stable at 1000MHz with 1.90V, with the same subtimings CryptiK is using. Even on 2T with even more relaxed subtimings it's impossible.
    The specific DRAM skews that worked well at CL7 don't work at CL8.
    What's your secret?
    Heh you mean me? Nothing really, just straight run boot from BIOS with the settings you can see. No idea what I have vNB set to for low FSB/ram around 1996 MHz, I think 1.43v for memtest stability.

    I don't use ram skews though, just leave them on auto.

Memtest would always error out after a few passes...

    For high clocks seems the 266 strap is favourable on my board. This REX is in 3D better than my previous one, but FSB is fully blocked at 635... bummer
    Where can I get BIOS 0002? It's not on the FTP. 635 FSB is pretty nice, my CPU tops out before that so I have no idea what the board limit is.

    When you are running 610 FSB + what vNB are you using? Do you just have stock cooling and if so what is your NB temp at. I find it impossible to keep it under 56*C load with stock heatsink & MX-2 with a fan on it.

    Thanks, now my temps dropped even more, so with more vNB I'm still getting lower temps than before.
    For high CL7 clocks with the D9JNL I had to tune skews manually, for the D9GTR auto works best indeed.

    Today I tested my D9GTR kit a bit further, after playing with skews, GTL and DIMM Vrefs and just upping the Vdimm to 2.20V and not getting anywhere I decided to loosen the timings and it turned out one stick doesn't like tight tRAS at all.



    Leeghoofd, this is for you! Any better?

    You can download it here: http://dl.dropbox.com/u/525714/Rampa...treme-0002.rom


    It was supposed to be a testing BIOS for my ASUS Rampage Formula but they gave me an ASUS Rampage Extreme BIOS.

    The BIOS has 2 new features. DRAM Refresh Period aka tREF and Special 133 Mode.

    This BIOS should give you better stability at high FSB because I've found that FSB 465MHz is about the highest true 24/7 stable FSB for my board.


    I'll share it with you guys so Leeghoofd doesn't have to do it because I don't know if ASUS want this BIOS to be released.

    Hey Daniel, that's getting better on the FSB side of things but PL 10... come my friend, you have got to do better than that!

    Shoot for PL8 and your performance will sky-rocket.

    Good to see the good old REX still going strong, i'd love to get my hands dirty on one again.

    Ok, now you've got it and I'll remove it again from the download link because I don't know if it's supposed to be shared and released.

    Have fun.

    You could do me a favour if someone could post some screenshots with EVEREST benchmark. One at FSB 470 and DDR 1253 tRD 6 with Special 133 Mode Disabled and one with Special 133 Mode Enabled.

    Edit:

    I don't know if you can do that using DDR 1253MHz and CAS 5 with tRD 6 so using your own DDR speed is also good. It's just to see the difference in the benchmark.

    Sorry guyz...currently floating off the coast of Saudi Arabia....won't be home till May sometime....hopefully somebody else can help you out with your requests...

    &...please excuse my ignorance...but special mode 133 allows you to do??? Pretty limited connection out here and couldn't read your thread on the Asus site.

    I don't know what it does. That's why I would like to see the benchmark.

    I think that if you enable it that there's going to be a strap change so it's easier to push the FSB. I'm not talking about 5 or 10MHz gain, I'm talking about >50MHz gain.

    Straps...oh boy...everybody seems to like the 266 strap and here I'm on 333 if memory serves. 400 is a dud on my board. I will give it a try when I get home....more FSB will definetly be appreciated as I'll be gunning for 650+.

    In your Asus thread (before Company filters shut me down) you were speaking about flashing procedure....do I have to use anything special like Afudos ES?? (I think I have one somewhere from when I flashed my Max F to Ram F.)

    @ Alien Grey - I missed out on the BIOS, would really appreciate it if you could relink fo a couple of hours so I can grab it to test. I know it's not official but I'm not going to bork my board and blame you heh.

    I'd run a bench but I've never heard of special mode 133. Is this a new thing in the 0002 version?

    Hello everybody. I'm here testing BIOS 0002. Flashing it went without problems, I used EZ flash 2.

    The only changes I have noticed are "DRAM Refresh Period" and "Special 133 mode"

    I focused on 133 mode and when I set it to enable the sistem doesnt boot, it says "overclocking failed", don't ask me why because I don't know.

    ATM I am using the same overclock that I had in BIOS 1202 (Q9650 @ 4050 MHz)

    I dont have much time to test but tomorrow morning I will continue.

    If you have any question about this bios I will try to answer it.

    Good night everybody!!

    This can only happen with ASUS.

    What if you up the FSB to >466MHz and use the 333MHz FSB Strap to North Bridge.

    Well, I have tried a lot of diferent things:

    -Rising FSB up to 467
    -Relaxing memory timmings
    -Rising voltages
    -Changing from 1N to 2N
    -And I have tried with all posible straps and with different memory dividers.

    Conclusion? WTF is "Special 133 mode" xD it doesn't work anyway!

    Why was it added and what is it supposed to do? (I haven't had a moment to test it yet)

    333 is nice for sub 600FSB action, you can go high on ram clocks... but for plus 600 you need to drop to a lower strap to stay high on the rams and sub 1000mhz on the rams... 400 is a no go here too... good luck on the 650FSB hunt man, I really think you got one of the good REXes...

    I got a NB pot at home if you need it :p

    Hey Leeg, that SS I posted a while back was with 333. So you figure 266 huh? Well, never had much luck with it but will certainly give it a whirl. Thanks for the NB pot offer but have a couple already...a new Otti NB to try, as 6+ months later...still WAITING for Duniek to make amends!?!? Hint hint. There, had to get that off my chest.

    You've played with this 0002 bios, can you shed any light on the 133 mode question??

    I'm also interested in that 0002 bios, can someone please share it with me as well?

    Eugene, PL8 is running perfectly stable now, required NB GTLVref +20mV.

    Everest is looking better now:



    This is my best 32M so far:

    nice runs CryptiK and Don_Dan

    CryptiK, maybe try All pre to act = tRP +1 (bios tRP + all pre to act auto)
    this should give full gain from tRP.

    would like to try 0002 here .. can someone help me too please
