Sorry, It's me again.

Behind the chips there are some tiny holes formed in square shape, I wonder what are they for and if it's okay to place a thermal pad on it?

An update to my yesterday's post: The 3 chips were hot in idle only if both power and data cable are connected (without plugging in the data cable all chips are cold). After leaving it overnight, all chips are found again and working fine. All chips now in the idle state are cold, so I guess probably there was a short circuit that caused the 3 chips to be hot.

Hello! I recently moved homes and today at my new place when I tried to run my R909, unfortunately, it shows 0 chips found. I guess something went wrong during shipping.

Anyway, I just dissembled everything. When it's connected to the power cable but without running the CGminer, Chip '1', '2' and '5' (which are on the same side) are hot while the other 3 chips are cold. I wonder in idle, should all chips be hot or cold? and what could possibly cause this ''half hot, half cold'' scenario? Many thanks!

Hello, newbie here and I'm also a newbie miner.

I just got a R909 and today I've been trying to connect it to Nicehash, which worked but xnsub is not supported.

The customer service told me to enable extranonce using the code "stratum+tcp://sha256.auto.nicehash.com:9200#xnsub", however, it did not work.

I wonder if there is any tweak that can make it work? Many thanks!
