Are there many other miners out there who are having significant issues with their Terraminer IVs? Mine is currently mining at ~1.1-1.2TH/s as one of the Goldstrike chips on the first board (CTA0) doesn't appear to be online. Originally both chips did not appear to be online for CTA0 until I upgraded the firmware to 0.6.48 (I'm currently using 0.7.6 with no discernible difference). It should be hashing at at least ~1.5-1.6TH/s but only tops out at just under 1.4TH/s when I cool the unit down to just below freezing at 1°C with CTA0 hashing at half the capacity of CTA1. The details of my unit are as follows:

I'm wondering whether I should just RMA the unit if I can (which I've heard can take up to 20 days and I may end up having to pay import taxes again when they ship the new unit out) or if I should open it up, voiding the warranty, and see if I can fix the issue myself however I highly doubt I would be able to unless it's something obvious like a bad soldering job or disconnected wire.
