One of the chips on an H-card received last week has been giving hundreds of miso errors per 5-min, and is giving no good results, but all other chips and cards, before and after in the chain, seem unaffected. Is there something I can do about it, or should I just write off that chip as bad and ignore it?
probably a bad chip. theres a few things you can try:
1) put the board as the last in your rig and/or try a different slot(s)
2) raise the voltage slightly. probably wont make a difference, but sometimes the chips seem to get themselves settled in with a little bit of heat/runtime. i had a chip go from <0.7GH for the first 2 days to being a totally normal operation after voltage tweaking.
3) look for any issues in the components and traces around the chip. (you likely wont see anything, but worth a try)
4) send it to me and ill test it in my system
