    Binning sempron

    in General overclocking

    Posted · Edited by Bilko
    Removed recalc part from link

    Ok I did some test with ud7 ver 2.0 and bios f5a 

    I tested 3 145, one stopped at 410 second stopped at 412 and the last stopped at 449 ?

    All tested with same profile, with dram set to ganged mode.

    For this I set vcore 1.45 cpu-nb 1.375 dram 1.79

    I used stock cooler plus a 120mm fan to cooling dram/nb.

    Next step try with hyper and unganged.

    Binning sempron

    in General overclocking

    I will try d9's when I will find some sticks.

    High vdimm for me is useless, with sempron from 1.72 to 1.85 I give same reference.

    It's chip related. Same settings give me 435 fsb geekbench 3 with 960t at 1.81vdimm.

    I think some chip have better imc, I just need to find another one :(

    With ud7 and biostar 890fx I never lost dual channel, only with asus or 990fx ud3 I see that problem.

    UPDATE !

    Im not passing to much time on the platform but binning for th moment is impossible to do (890fxa-ud7) its seem to be limited at around 385-390fsb whatever cpu i put in it, overdrive or not, single stick or 2. FSB seem to scale with VID northbridge but not that much, i know that board do much higher, i think ale belo or cnzdrn push it between 415 and 430. maybe someone has a idea ?

     

    Ganged help but not at this point!

    The main problem you have is dram.

    For bclk with ud7 my best result is based on elpida hyper, high binned hyper, bbse is good and psc is the worst dram to use.

    All sempron 145/150 that I tested can do atleast 408 dual unganged or 415 dual ganged.

    Single stick can do the same you can do with ganged.

    Best stick slot 3, the second slot 4.

    I bin each stick individually, max boot and max on Windows. 

    PS I use ud7 rev 2.1 maybe rev 2.0 works different 

    PS 2 cpu-nb is the imc voltage, if you set 1,3-1,35v you can do about 2800 imc freq and push dram to max reference they can do
