Hello,
I have around 30 AntMiner u1s. During testing I found some don't give hardware errors at 1.8ghz and others at 2.0. Is it possible to run them at different frequencies on the same computer/miner software and if so how would I go about doing this? Thank you for your help

You should be able to have different settings per device, for example BFGMiner (see the readme.txt file) has the option
--set-device Set default parameters on devices; eg, NFY:osc6_bits=50

You'll need to do some research and find the correct syntax for setting individual devices on Antminer U1. Suggest that you read https://bitcointalksearch.org/topic/bitmain-antminer-u1-tips-tricks-390929

An alternative is to "split the difference" for the two. In other words, run both at 1.9 GH/s.

You can get 1.9 by using a frequency value of 0901. While I only have about a dozen of these
I have yet to see one that doesn't run smoothly and error free at 1.9 GH/s.

Most folks seem to focus in on 1.6, 1.8, and 2.0, without knowing that the "in between"
speeds exist and work fine. It's all in the "8" value within 0981 (or 0781). Changing out
the "8" for a "0" let's you get the "odd" speeds.
