    may reacted to NicoD in Xulong Linux 4.9 images for H6   
    I've just installed it, and first impression is, it isn't much better than before.
    It's unstable. Runs at 1.5Ghz, but seems a lot slower than others at the same speed. 1.8Ghz isn't possible anymore.
    Temperatures are of course better now.
    Here a 7zip benchmark with stock settings.

    I've then set the governor to performance and everything starts to lag like crazy. 7-zip results are very bad.

    may got a reaction from iamwithstupid in Orange Pi Lite2 - heatsink?   
    I bought a large heatsink size 37*37*24mm and modified with my dremel. And then connect the heatsink and the soc with a pice of copper and 3M™ Thermally Conductive Adhesive Transfer Tape 8810.
    I've learned that both the ap6255 module and the ddr ram onboard generates lots of heat.
    ap6255 gets overheat under heavy load and stop working until core temperature drops under alert temperature without a proper heatsink
