    How is LN2 doing for PD? Good/bad batches like BD?

    I've been out of the game a little while I have restructured my life.

    I keep seeing decent LN2 results for CPU-Z with Piledriver every once in a while on HWBOT.
    Are there still many duds out there, or have AMD/GloFo finally figured out how to make consistent batches?

    I see FlanK3r got 8.1 GHz. Nice!

    After testing two FX-8150 on LN2 and only achieving 7.3/7.1 GHz on either with worse modules topping at 6.8-7 GHz and two having dud IMCs (2400+ unstable w/ PSC + 2000+ unstable w/ Hyper) I don't know if I want to bother dumping more money on FX-8350s.

    An early batch 8150 did 2500 dual channel 7-11-7 pretty easy for me, go figure...


    So...late PD chips still holding up?

    Thanks!

    On average the difference between max air and LN2 CPU-Z is around 2.8 - 3.2GHz (Vishera).
    2.4 - 2.8GHz for Trinity.

    From my experience, Vishera looks better than Bulldozer not monly at air/watter, but with LN2 too. I tested few FX-8150/8120s and the best was 7800 MHz FX-8120, the best FX-8150 only near 7500 MHz. First Vishera hit easy 8 GHz , and this one is not the best what I have (comparison in watter cooling condition).

    Sweet!

    I should try a few.

    And good is, power consumption after OC is lower than with the same settings at Bullodzer .

    What's the cheapest board one would need for high cpu-z validations on dice? Not sure how far they'll go on dice though...
    Also, how good are the lesser core variants at that or max ddr3 validations? Might get a cheap am3+ rig for that purpose alone.

    What would a good VID be for these?

    I just checked and mine is 1.325v
