    Just bought an RE to play~ mind if I join in this discussion to contribute
    Yesterday got some test. Settings as below (briefly)
    FSB: 540
    Multiplier: 8
    divider: 200/667

    Voltages:
    CPU: 1.35v
    CPU VTT: 1.19v
    CPU PLL: 1.55v
    vDIMM: 2v @ 7-6-5-18
    vNB: 1.51v
    GTLs:
    CPU 0/2: +50mv
    CPU 1/3: +10mv
    NB: +40mv
    1.5v SB: 1.55v

    Others on auto

    With this strap I was able to boot at tRD = 8 and Pass dual PI 32M
    With 1.41v vNB I got BSOD right before I saw the desktop
    With 333/1066 divider the machine was bootable but BSOD when loading Windows using tRD = 8

    What's interesting is, compare with the anaxxtech's review (Rampage Formula)
    It has a formula about the calculation if the machine will be able to POST or not using a certain tRD.
    While 333/1066 divider's value is bigger then 200/667 in terms of theory we should be able to boot up and load to windows without a problem using the same tRD value.
    The problem is, with 333/1066 divider tRD @ 8 is completely unstable while 200/667 can boot up and pass dual 32M, even memset to tRD = 7 for a memory benchmark (possible to pass PI as well, haven't tried)
    Any suggestions and comments on that?

    And, I have a problem on overclocking my CPU to 4.5Ghz, will post the problem later. Still looking for assisstance
    (Sorry for my bad english)

    EDIT: The scene as below
    FSB 500 Multi 9 4500Mhz
    vCore: 1.3875v 1.392v Load LLC Enabled
    With this setting I can pass OCCT for 2 hrs mixed test
    But in ORTHOS I wasn't able to Pass even 1 minute and always get the same error: Final Result Mismatch
    It does not make a single difference by rising the vCore to 1.425v. However it do pass dueal PI 32M...that's confusing...please help
