I disabled all but core0 to do a 4.5 Ghz Prime95 run.
My board hates anything over 3.8 or so with 6 even though as a dual core each one will do 4.2-4.4...

Maybe the one you left enabled was your weak core? Or did you try others?

That's because your board is a 4+1 phase and your VRM/MOFSETs cannot take the voltage required to run the TDP heavy X6.

That's the general idea.
Was just providing a scenario why one might disable cores to address the question in OP

bummer.. well if you ever do again be sure to try all the cores.

Disable core 2 and 3, for the best heat dissipation in the IHS.

Don't forget they start counting at 0. I also wouldn't treat your "core0" as the weakest core, just the core that does a little more hardware management than the others. Core0 is the master core, all the others are its slave, so the boss needs a bigger paycheck (i.e. voltage) because it has a harder job



While it does allow more headroom for OC, it wasn't enough to be a smart option over 6 cores for me. Best of luck to your experimentation.

So I was right.. except I had them labeled 1-6 not 0-5. ... curious to where you found this?

Found it half a year ago when I was overclocking/writing+sharing the data for the first time:
http://www.overclock.net/amd-cpus/85...uest-4ghz.html

I believe its just a spreadsheet of BIOS templates, but I kept track of temperatures, failures, error types etc.

I was experimenting with disabling cores for not only temps, but higher overclocks for gaming/benchmarking. Had some cool records in Heaven, but I ended up selling my mobo/chip for this bad boy... now my comp is just a "dime a dozen" with all those i7 folks

It was just a Google Image search: "Phenom II X6 die", they are all the same, so the models didn't matter.
