avalon4: max gh/s not going above ~200 gh/s

Hello,
Just purchased an avalon4. Using with a 1000w HP psu. The psu is able to power an antminer s5 just fine with speeds up to 1100gh/s. But cgminer does not show the avalon4 miner going above ~200 gh/s. This is regardless of what frequency, fan speed, or voltage is supplied via the command line. Is there a cgminer option maybe under pool settings that needs adjustment? What else could be the issue here?

Started via:

Code:

sudo ./cgminer --avalon4-fan 10 --avalon4-freq 420 --avalon4-voltage 7625 -o stratum.f2pool.com:3333 -u {user} -p {pass}

Edit: Running from a desktop machine on Linux, plugged into the USB. Cgminer version is:

Code:

$sudo ./cgminer --version
>cgminer 4.9.2

Edit: Just want to also mention that there are two avalon4 miners and both produce the same result. They are not running simultaneously. That is, neither machine goes about ~200gh/s when run individually.

Here is cgminer running...
