    OOPS! I made a mistake in reporting what I was seeing. I THOUGHT I was at DDR 3600 because I was reading HWinfo and AIDA. But ACTUALLY, I was at 1066-> 2133!
    I explicitly set speed to 16-16-3200 at 1.35 v and it would not post!

    I think Thaiphoon just reads what's in the specs, not actually what the memory is DOING so I checked with CPU-z
    CPU-z says I am running 15-15-15-36 tRFC 374 clocks CR 2

    I

    This 'neo' memory is marketed for AMD. And I know that AMDers like tight timings because high clocks are not possible with infinity fabric. (It desynchronizes above 3800. So the hocus - pocus of this memory is that it likes tighter timings and indeed, the Maximus Hero has 'automatically' set it for CAS 15 and 3600. I dont know why it did not do this from the start and required me to visit XMP 2 first. If I try to boot with XMP 2 , it fails.

    I dont quite understand? Yut get into BIOS .. chose XMP 2 .. then goes back to AUTO? and set manual 3600 mhz? or what? won the AUTO just default to 2133 mhz?

    And did you actually get them down on CAS15? sounds crazy at 3600 ?

    Please explain in detail, sorry for not understanding.. thanks.

    I read you later posts..

    No matter WHAT I do, I can only get 3333mhz stable.. 16-16-36 2N

    I even tried your 17-17-38 no luck ..

    it sucks when you paid for that.. I have 4 x 8 gb modeules btw

    I had them in slots A1 and B1. Got them to 12-12-12-33 at DDR 3000.

    All rigth.. I guess ill have to settle at 3333 mhz... the difference between that and 3600 is basically nothing but its just a principle for me! that buying something that dosent work as advertised..

    sigh!
