I thought my Opty 154 was crappy, but I thought I should give it a try... And OMFGZZZZZ!!!! S.I.H.!

Opteron 154 wr, and Opteron overall WR, and s939 locked multi WR as well:

This thing was so hot I had to use a pot (normally I use a heatsink with dice on it for B1 chips and other coldbugged stuff), but it worked nicely. -15c/1.824v. temps measured in ITE SmartGuradian, as the temp sensor crapped out at 2c.
