Thanks for answering my questions about overclocking and power guys but i had one more question i was hoping you guys could answer, i just got my antminer s1 in the mail and set up yesterday and last night i overclocked it to 375ish it ran okay for a little while then a bit later i noticed that it was not running at top speed. It was running at 125 GH in the over view tab i saw that about 3/4 of my chips were not working, so i rebooted the antminer several times and it changed nothing then i shut down the psu it was on for about 5 minutes and the chips came back online, ive googled every thing i can think of but cant seem to find an explination, should i be worried about overclocking or is this normal?

these are the settings i used and there were minimal hardware errors.

option 'freq_value'     '5f05'  #350M
option 'chip_freq'      '393.75'
option 'timeout'        '36'
