Use additional cooling to bring the temperature down on both the ASICs and VRMs. The cooler you can get them the more efficiently they will run. My first LV08 is still cracked open with a 120mm PC fan on top of the heatsink. Otherwise, put a fan up against (or close to) the intake vent and you'll see the temps drop.
At 600MHz and 1.25v on the core of the ASICs, my LV08 power is showing 109 watts with the ASICs at 47c and the VRMs at 53c. Power at the wall is 129 watts. The hashing rate sits right on 5TH/s!
1.200v is too low for the LV08 at 600MHz in my opinion...
EDIT:
If the TPS546 current approaches 30 amps, it will start to throttle. The initial setup for the TPS546 is OC_WARN_LIMIT = 25 and OC_FAULT_LIMIT = 30. So maybe need to increase these parameters. The TPS546 is capable of up to 40 amps of current!
I am pretty sure I previously ran into the 30 Amp limit.
With the new beta firmware this is no longer the case.
I am keeping track of temps/freq/voltage in a spreadsheet but I just kept hitting a ceiling without anything overheating.
The PSU inside the LV08 is rated 180watt MAX on the load side with 10CFM airflow x 80% = 144 watt continuous.
But since I am in the USA and only able to feed it with 120volt AC it has to be de-rated with 60% :

I have just increased the voltage on the asics to 1215mV and now averaging 5.03Th with 120.7Watt in the gui, 53C asic temp, 64 VR temp
