New boards promise to enable hidden AMD Phenom II cores

  1. On Tuesday, MSI and Gigabyte were the latest to join Asus in announcing official plans to support hardware based methods of enabling the hidden cores found in AMD's new dual, triple and quad-core Phenom II processors. In scarce detail, motherboard manufacturers have been outlining their own hardware-based, BIOS-configured solutions which will allow users to enable or disable cores as they please. Not surprisingly, each manufacturer will have their own name for this technology such as "Core Unlocker" for Asus and "Core Boost" for Gigabyte.

    Will be interested to see if AMD has any official comment on this.

    Wondering how how AMD will take this. I see them not being very happy about it.

    I think AMD would be happy, because they would sell a great deal of these CPUs that have thier cores dis-abled (due to what ever reason), and the majority of the people who buy these CPUs are OC'ers and tech savvy users. People who want the latest and greatest and do not desire to either upgrade thier mobo will just buy the CPU that has all of the cores active or they do not care nor might not know that the CPU they bought has two hidden cores. Win-win for everyone.

    Hmm, well my Gigabyte board I have (which was released in 2009) unlocked my 4th core in my Phenom II X3 720 BE without any problems and I'm currently running it overclocked to a 3.51ghz with no issues what-so-ever.

    I think the difference they are trying to promote here is 'ease of unlock' being a hardware based unlock as opposed to a software adjustment via ACC, and maybe getting a slightly higher OC of the 'defective cores'.

    I just bought a M4A89GTD and a Phenom II X2 550. I tried unlocking 4 cores, it wouldn't boot Vista. It just sat there in with the green bar scrolling endlessly. Thankfully the BIOS had an option which let you try each of the two locked cores alone, and on the last try I unlocked one of the cores, and have a X3

    However, different programs recognize it differently, some call it a X3, some call it a X4, even though the 4th core is not enabled in BIOS.

    Cores are usually disabled for a reason?
  9. Cool
    Some cores are disabled because they have "issues".
    Sometimes cores could be disabled to make a 4 core a 3 core (to sell w/ nothing wrong).
  10. This is very good, I certainly hope these motherboard have more than two USB 3,0 and eSata connectors?

    I would think AMD does not care if they can be unlocked, only a few that take the time to do this and properly check the stability. I would believe only a few run with lock cores opened, but this could help improve that number.

    Can the Athlon 11 be made whole with these motherboards? Can the L3 Cache be opened easily on some of the Athlon 11 processors?

    I was surprised to discover the 890 motherboard I looked over did not come with numerous USB 3.0 connectors...
