Sorry if this was already asked, I just couldn't find it anywhere.  But here's my question:  Are you able to clock the Antminer S1 at a frequency that isn't something like  350, 375, 400, etc.  Something in-between those numbers.  I recently received an Antminer S1 and had it clocked to 375 because my PSU doesn't have enough watts on the 12 volt rail to go to 400.  I want to get the most out of my miner before it becomes non-profitable though, so can I clock it to something like 380 or 390?  I think I remember someone doing 389.9 because it ran better than 400, not too sure.  Thanks and sorry if this is a stupid question, I'm new to Antminers a bit.
