Just FYI, I have this fixed now, and you were right on the money. I |
| 21 |
wouldn't have believed it if I hadn't seen it, but it was the RAM. I |
| 22 |
replaced the OCZ memory with equivalent parts from Crucial, and the |
| 23 |
system is fine now. It still seems strange that many things seemed to |
| 24 |
run fine with the old RAM, except for bunzip2 and md5sum, and now |
| 25 |
everything is good -- only some code is intolerant of bad bits? It just |
| 26 |
seems wrong.... Anyway, the system is rock solid now. |

Thanks for the help, to everyone who responded. I have the old OCZ |
| 29 |
memory on another board, where I can do some testing. I'd like to see |
| 30 |
if I can get it to work better declocked, but in any case, it has a |
| 31 |
lifetime warranty, so it will be going back. |
