    Hey guys so im still tweaking and testing PSC Memory,Dram 1.93.5v air ambient temp 25c,cpu SS -25, 2740MHz 7-12-7-30,got another 20Mhz out of it on 8M Pi
    Little stability 8M Pi ,was so close to getting this pass 32m Pi as well.Not efficiency testing

    Yeah Ive been bit bored lately so just testing memory on air until I get a refill.The imc has a wall at about another 3-4 MHz on air so its funny how its stable 8M Pi stable at 2740MHz and if i bump it up 3-4 MHz thats its limit and its not really stable then even on 1M Pi

    Hey,so I been still pushing along,finally got 32M Pi to pass Memory @2742 7-12-7-30 on air,temps were little bit colder about 15c to 18c, CPU -25 Dram 1.94 V,had to up dram V a bit ,the key was bit cooler temps and when I got it passing half way was working out correct vtt and imc,to much or to little off either was the different s,also messing with some settings in bios like auto Vs Extreme i found sometimes auto was better,this seems to be the best stick of the set.

    Thanks guys,
    @ Robbo yeah I seen Sam OCX run 1.97v on his on air so i thought why not,I even went 1.945 trying to get 2747Mhz to pass.May not scale any more on volts on air tho

    i didnt see any scaling on cold past about 1.95 myself. seems that's the voltage PSCs like

    on BBSE it was actually around 1.88

    i bench all ram that high on air, including new samsung ICs. they can all take some serious punishment

    I've benched psc at 1.95 on air, and Samsung on air at 1.96. People do 2v on air on sammy on xs.

    Yeah I would go higher on air but scaling stopped for my memory on air I believe

    The hardest thing about these clocks is getting it 32M stable that's what I thought myself was the cool part,IMO this is we're us as "Overclockers",our tweaking skills come into play
