    Is this going to overclock well? ASrock 939dual / 4 x 512Mb Corsair XL 2225 / Opy 146

    Since my Asus A8V isn't overclockable I'm thinking of selling my current 3500+ and A8V and treating myself to an opy 146 and ASrock 939Dual (so I can continue to use my 6800GT)

    Do the Opy's have the problems with the memory controller that newcastle/winchester cores had - will I be able to run in T1?

    Does the 939dual have AGP lock? I've seen reviews of the board reaching 280mhz HTT so I'm assuming this must be the case...

    What kind of overclock could I expect with an opy 146? Would be looking at getting 2.7ghz (270HTT x 10multi) with my corsair XL 2225 ram (could relax the multiplier or just set a higher divider...)

    Any thoughts?

    You'll have to run 2t with 4 sticks of 512mb ram which is a slight (~5% or so) performance hit.

    280htt should be possible, I would run 280x10 with a 3:4 divider. This would put your ram at 210mhz which it should handle as most 2-2-2-5 ram is tccd based so can clock up to about 215 without having to drop timings.

    What a well timed thread, I'm about to try exactly the same thing except with 2x512mb Crucial Ballistix PC4000!

    Also it'll depend on what stepping Opty you have.

    I recieved an Opty 146 CACJE stepping, and these need a little more voltage to reach 2.7-2.9ghz, apparantly, new to this whole clocking thing myself.

    Currently running:

    146 CACJE @ 2700.88 MHz Prime Stable
    Mutliplier = x10
    HTT = 270
    Voltage @ 1.5 (Burning it in, might be possible to lower it)
    CPU Temp = 31-33c IDLE
    FSB = 270
    RAM = 180

    NOTE: Whenever i tried altering ANY kind of setting in clockgen or the ASUS AI Booster above 2.4ghz the comp froze, not sure why. Manually changing the settings in the BIOS worked perfectly.

    I'm going to drop the voltage tonight and see if its still prime stable at this speed, then try upping the HTT a little more.

    If anyone else has a 146 CACJE stepping i'd appreciate what speed and settings their running on please, seems hard to find much info on these steppings so far, thankyou.

    u will only reach 2.75ghz as the board will not overclock higher, if u use an unofficial bios u;ll be fine, u also cant change volt setting much without a simple(ish) voltmod

    Update: Dropped CPU Voltage to 1.475 and upped HTT to 290

    Currently running:

    146 CACJE @ 2920.88 MHz Prime Stable
    Mutliplier = x10
    HTT = 290
    Voltage @ 1.475 (Lowered from 1.5v)
    CPU Temp = 33-34c IDLE / 40c Full Load
    FSB = 292
    RAM = 194

    Seems like i have room to hit the magic 3ghz mark and possibly more

    Nice clock for a Cacje.. you need to update your sig if it's prime stable
    Wish I'd gone for the Asus premium board ... and not the standard

    where would you get an unofficial BIOS? Not preapred to volt mod ...I'd be happy with 2.7Ghz

    Get OCWBeta1 BIOS from www.ocworkbench.com/asrock

    It's the best one. I'm using it atm with my Opty 146
