I know I probably squeezed the raspberry. though the usb hub only two devices connected to it, mouse which I rarely use but connected most of the time and bluetooth
the hdd is the worst of all, particularly this one, even on older pcs struggle.
I checked config.txt and more about overclocking, and tweaked it , and now not just it is much snappier, this usb power supply now seems to work fine. I removed overvoltage which was put by default raspi-config overclocking when choosing 950
I removed overvoltage, reduced gpu_mem to 64
core. I simply made it same as one of the posters on this thread: http://www.raspberrypi.org/phpBB3/viewt ... 35&t=24636
now emulationstations even dosbox works like a charm. it was too slow.
Still not sure why the 2.1A/ea port usb psu can't handle overclocking when overvoltage=6 while 1A can handle that but have to connect hdd extra power to PC or else it resets when under heavy hdd work. Both of them has 5v written on them as output.
The 2.1 one still gets hot quickly. normal?
tl;dr summary: now works after removing overvoltage from config.txt, but usb psu still gets hot, hope it is normal and doesn't explode
