Ya, I painted up the card with LET after I was done, so not sure where that loose chunk went as I forgot to grab it after I saw it in the pics, but it probably just fell off on the floor.
The card ran well. Memory clocks stopped at 1050MHz, but I didn't screw around much with memory voltage yet, which is what the mods are for... So hopefully I can find more headroom. I could really use something like 100MHz more on the memory, but that is probably rather greedy.
Core stopped at 1025MHz with 1.362V applied. Tried a bit with 1.4V but that didn't get me any further.
It likes cold down to -130C, then starts artifacting pretty heavily, so no full pot benching on it.
My bench scores so far are lousy on it, as I was benching without hwbot access (their server was offline for about 24hrs), but my clocks and certain subtest results indicate with some LOD tweaks, a driver switch, and maybe one other change, I should be able to put up a couple top scores with it.
If the memory gets further, it should help.
