    Dropped a channel of ram a few days ago, set all my clocks back to standard on my system that is in need of an upgrade and gave it a go for laughs.

    Using superpi 1.9, my beast did 32M 24iterations in 18min 57.809s


    Nailed it.

    Just on any of you guys getting a KP pro memory pot,Dino told me a little while back to take my spreaders of my memory and just clamp the memory pot straight onto the bare dims,this is how I ran them yesterday and it is by far the coldest temp I have reached that allowed me to run my latest times.
    Just a temp graph on HS
    Normal memory HS -120 max
    EK alloy spreaders -140-150
    No spreaders -170 no problem
    The best thing about no spreaders is temps drops way faster then the other two ways too,this is what you want because the best results can come from the first 30 minutes of benching

    Thank you Dino for advice

    Splave posted a guide on how to get the ney pro mounted really well with naked sticks on hwbot and kingpin forums, using a very thin double sided thermal tape. And you can buy the thermal tape he uses at pccg.

    Yeah I did see that,last session I ran no paste on my memory's and it ran solid for about 3-4 hours at -170,I normally use paste on the EK spreaders.Im sure splaves tape way is good but never tried it

    for the sake of saving peoples searching, that would be this guide.

    i have a heap of that tape here, will use that :) when you use paste between dimms and the spreaders, the buggers keep slipping out when you are mounting/removing the pot... PITA
    was gonna use the tape next time i try, but might save it for use on better sticks perhaps (these ones were pretty shit)

    edit: just ran this, my first in the 20s;

    now im not sure if it was the timings change, the maxmem change, or the waza size change that caused dropped the times
    *facepalm*

    might revert everything bar the timings and test again.
    no doubt 6 hours later i will realize it was the combination of all 3 :lol: and that i wasted my day, but i wont know for sure what worked until i've tested regardless

    wow bull, thats gonna be a mad CPU for water or your phase.
    edit: oh and nice ln2 freq and uncore!
    hope the IMC holds up as well, good luck :)



    i've been busy testing various maxmem and waza sizes today, my last sub was a little slow at start. apart from TRFC change it was all the same timings as last sub, so overall made some progress :)

    Dudeeee lets see your all out time now bull!!

    Dave, how low you think you can get tRFC down on those sammy? I think i did 102 or something for XTU.

    Plugged in my haswell just now. Probably won't get a look in before Sunday night, but yeh.

    Nice.. Trfc doesn't like going below 105, even 105 isn't guaranteed (was failing runs). Raised back to 106 so I could be fully stable for all the runs I needed to do yesterday.
    Pretty happy with the setup ATM its working nicely
