Phenom II x3 720 with 6 cores???

post #1 of 28
Thread Starter 
So, I updated my BIOS today because of some RAM compatibility issues I was having. The motherboard in question is in my sig. I updated to BIOS v. 2104 which according to the notes improved stability, memory compatibility and included support for the newer x6 CPUs. I did everything by the book pretty much, downloaded my latest BIOS revision to a flash drive, reset the existing BIOS to default, rebooted, opened up the Bios flashing utilities option and proceeded with the update. Upon rebooting, I went back in to unlock my CPU like I had it before ( X4 @ 3.3 GHz) and noticed when I enabled ACC and Unleashing mode, it listed options for 2, 3, 4, 5 and 6 cores??? Anyone else notice this with a BIOS update and this processor or any phenom IIs??? Below is a screenshot for proof of what I'm talking about.

I am just wondering if this is just my BIOS telling me that I have the option of adjusting UP TO six cores, since this is a C2 revision of the 720. I doubt that I'm that lucky, and I seriously doubt that if this CPU does indeed unlock the 2 extra cores (I've unlocked the stable 3rd and 4th cores successfully) are probably nowhere near stable. Just wanted to get others input on this since I couldn't find any topics about it.

Only the t series of the Phenoms have 6 cores. There were some 9xxt 4-cores, but they were OEM only and short-lived.

Sounds like your BIOS is just screwing up. :\\

C2 revision is old, C3 is the newest which the Phenom II x6 would of been based on.

Even if you left all on the [on] position, you still wouldn't have six cores. This function is only possible on quads that could have been 6 cores, which are all oem cpu's anyways.

I think it might just be your Bios telling you that it can handle a 6-core CPU.

my mobo shows that too... though it doesn't matter if I put the 5th and 6th core on or off, it is always the same number of cores (in my case tri-core, the 4th is unstable)

Yep ASUS bios does this.

Exact same on mine.

Core control on ASUS AMI BIOSes is buggy as hell. 6 cores on all CPUs and some combinations don't even work.

EDIT: Could you turn all cores on except 2nd core and tell me what happens?
