Unlocked Athlon II x3, want to relock L3 cache

post #1 of 12
Thread Starter 
I recently got a new motherboard and gave a shot at unlocking the fourth core on my Athlon II x3 445. The core unlocked and I also got 6mb l3 cache out of it, but after some testing I believe the l3 cache is bad (I went through and tested each of the cores one at a time by disabling three out of the four cores in the bios with the l3 cache enabled) and I'm trying to figure out how to re-lock the l3 cache while keeping the fourth core. The motherboard is an Asrock extreme4 970 and core unlocking is done using the Turbo UCC function.

Do you have a tab that looks like this?

462

You'll want to set it to BSP only.

I can find nothing of the sort. By bios, I meant uefi, so of course mine doesn't look exactly like that, but nowhere, under any options, can I find anything that relates to L3 cache allocation.

Why do you think the l3 cache is bad?

You may have luck getting the l3 cache stable by slightly increasing the cpu-nb voltage.

what it sounds like to me is you have a bad core that is the reason AMD disabled that core and made it a Athlon x3and not a 4 core with L3 disable the 4th core and you will be good to go

Thread Starter 
Continued tests show that at minimum the l3 cache is unstable. I went through and tested each core individually with the l3 cache enabled and each time it would bsod on startup. Changing the core and cpu-nb voltages don't do any good. So is there really any way to disable only the l3 cache while leaving the 4th core unlocked?

as I recall a 4 core AMD chip needs a L3

not sure what to tell you but acording to the AMD site a Athlon chip has no L3
post #10 of 12
It's not an Athlon chip, it's a Denab with bad L3 cache and 1 bad core, rebadged as an Athlon. There are no L3 cache controls in bios,ACC either turns it on or off.To turn it off you would have to disable ACC.
