Also, how are batch 2s getting 14.5k sols/s? I haven't gotten mine yet but from what I've read if I understand correctly they locked them down so no more OC.
They tried to lock them down but the workaround to overclocking them is pretty simple. You just have to hit F12 in Google Chrome, inspect the HTML and change the overclock value for the option to whatever you want.
There are multiple posts on this. You can find one of them here:

P.S. This applies to @steemboatwilly's post above as well.
