    If all Ram settings are on Auto, the computer rock stable with this Vcore (1.24375V), Uncore (17x=3400MHz) QPI (1.355V) and Ram (8x=1600MHz).

    I don't want to use the Rams on 6x=1200MHz (I'm sure on this freq work with 7-7-7-24-1 even faster), but it will be a big system downgrade. These rams should be work on 1600MHz with 7-7-7-24, but even don't work 8-8-8-24.
    Maybe RMA?

    With F8 final Bios they worked with 10-7-7-24-1 (I haven't tried less than 10) rock stable.

    I only suggested that for testing purposes, to see if the ram was what is holding you back.

    Yes, maybe RMA the ram as it sounds like they are not functioning properly possibly.

    Can you test CPU at stock Blck and use x12 ram multi and see if they function at 1600Mhz with spec timings?

    CAS 10 is NOT Acceptable anytime! Unless you are at 2400+ Mhz

    CPU 19*133 1.24375V ; Ram 12*133 1.66V; Uncore 24*133
    7-7-7-24-1 ; QPI:1.355 ; QPIPLL:1.00V ; IOH Core:1.00V ; ICH Core:1.00V
    Freeze after 15min. It's the best til now!

    Interesting:
    The same settings with higher voltages (QPI:1.395 ; QPIPLL:1.14V ; IOH Core:1.14V ; ICH Core:1.14V) make a restart after 5min!

    I really don't understand it

    7-7-7-24-2 ; QPI:1.395 ; QPIPLL:1.14V ; IOH Core:1.14V ; ICH Core:1.14V

    More than 5h long Prime stabil, then restart. So You have the truth, it's maybe not Ram problem.

    Why you don't try 21x multi [21x180]? it is much easier to get it stable compared to 200BCLK

    My system is stable at 19*200 but just with slow Ram settings.

    But it seems to be at last I found the solution. Upped the Ram voltage to 1.7V and now:

    CPU 19*200 1.24375V ; Ram 8*200 1.70V; Uncore 17*200
    7-7-7-24-2 ; QPI:1.395V ; QPIPLL:1.20V ; IOH Core:1.20V ; ICH Core:1.16V

    stable. Tested just only 50min.

    Maybe the F9 final bios make more undervoltage then the older version.

    What is this setting you mentioned changing above from 1 to 2?

    777-24- 1/2 This 1/2 one, what is that? Is it command rate maybe, sorry just wanted to be sure. 1T should always work for you unless you got $10 ram.

    I would try 1.4+ QPI instead of ram 1.7v, that would be less harsh on your CPU. And I would also suggest more IOH, like 1.20-1.24

    Yes, the 2 is 2N (or 2T somewhere) the command rate setting, sorry. I found somewhere on a site. It was mentioned this info direct from the OCZ support and about my Rams. Maybe will work CR1T, but I haven't tried it yet. I'm happy now because of

    CPU 19*200 1.24375V ; Ram 8*200 1.70V; Uncore 17*200
    7-7-7-24-2 ; QPI:1.395V ; QPIPLL:1.00V ; IOH Core:1.00V ; ICH Core:1.00V

    settings was stable more than 8h Prime test.

    I would try 1.4+ QPI instead of ram 1.7v
    I've tried it, see my No 25 post, without any luck.

    Ahh well if they suggested 2T for your ram then it may not be very good ram if it has to run at 2T. Was it cheap?
