Gave up trying to get the benchmark to work. Went straight to xmrig 4.2.1.
edit/update: Thanks for the detailed guides in this thread. Using turion and the custom bios for overclocking, was able to get 12.8khs. Very happy.
I am building out another identical setup but after flashing the bios, CPU2 does not working. Meaning, if I take the CPU out of CPU2 slot, it boots. If I put it back in, it doesn't boot. I tried flashing the original stock bios but that didn't help either. No bios beeps, no screen, nothing with CPU2 in. I checked for bent pins but don't see anything. Have you experienced that with any of your work?
For now, I will have to just use 3 CPUs which seems a little like a waste but better than nothing I guess...
On the defective CPU be sure the pads on the bottom are clean and that no thermal residue is on any of those pads. Some of the ones I bought had thermal residue on the pads.
I examine the pads using a high power bright light and a magnifying glass.
Use Isopropyl alcohol to clean the bottom pads on the processor and canned air to dry the pads.
