    You should also test all of this Vtt/MCH Core with MCH Ref in Auto to see if that helps as you really might not need to set it until you get your settings all finalized

    You should be able to use 7-8 easy on the B Strap, but then again you may not be able to with 8GB?? Sorry I have not tested much with 8GB, this may be one thing that is limited by that amount?
    Hi Lsd,

    Thank you for your reply, time and hard work!

    You helped me alot with overclocking!!

    So second, I will try playing around a bit and see if I get a tRD of 7-8 working.
    Again, thanks alot for now!

    Regards,

    killman

    p.s. ofcourse I'll let you know if the settings worked... .

    Hi Lsd, :)

    Tried various voltage values on MCH and Vtt. Computer wouldn't boot at a 7-8 tRD value. It was great fun to try though!!

    I don't mind.

    The settings I got now (working and stable):

    tRD is really the only sub-timing worth tweaking I think, so if you hit the lowest value you can achieve there then I wouldn't bother trying to lower the others.
    Voltages look good, I can't see a reason to not run this system 24/7 with those settings.
    If you want to tweak more, I would go higher on the CPU, if you have a decent cooler that should be no problem.

    Hi Nickel020,

    I already tried that out. Wouldn't work with CPU and RAM 1:1. I think the problem there is the RAM amout (so the 8GB). If I'd go higher on the FSB 1:1 the computer wouldn't boot, but that isn't a problem because it's stable and very fast now. I also have Vtt on 1.2V and the references a bit lower then auto. I read the article of Lsd about the changes that made Vtt. I think I begin to understand that a bit more.

    Again, thank you guys for helping me out! It was great to seek thing out, to try and 'reach' a certain value.

    Regards from the Netherlands,

    killman

    Ya, some memory just will not do it, but I think yours should, but then again maybe the 8GB amount is why it wont.

    Did you try this with all other timings loose (High)? If not you should, I see tWR to low right now (FOR SURE), that could be it but maybe not so I would set them all high before trying to lower tRD. Did you try with higher Vtt, maybe 1.28-1.32, this could help alot when it comes to tRD

    Anyhow, nice to see you have a stable system and are happy!

    Post back anytime if you start tweaking things more or need some more help or suggestions

    Hi Lsd,

    I tried lowering the tRD value with the following settings:

    tRRD...........................................4
    tWTR.......................................... 8
    tWR............................................ 10
    tRFC........................................... 88
    tRTP........................................... 8
    Command Rate (CMD) ....................:2

    So, that are the values you suggested before.. I used them..

    Yes also tried raiseing the CPU Vtt to 1.32V

    Regards,

    killman

    p.s. If I need help I'm sure I'll return to this great forum!!!
