I've got two troublesome blades that I think may be hopeless, but I figure it doesn't hurt to ask.
The first one hashes, but several of the chips register a clock of 999 while still showing O, but it cripples the cubes efficiency down into the high 50's and low 60's. In the first pic you can see some bad soldering in two places. Anyway to clean it out fairly easily?
The second one kills the whole cube regardless of the slot it is installed in. In the second pic you can see how bad the pins look. There was a lot more (solder? flux? crap?) basically connecting the pins together that I tried cleaning up a bit, but it still looks bad and doesn't run.
Anyone have any suggestions? Also, is there anywhere one could purchase replacement blades?
Thanks for reading.
