How to unlock the Phenom II x2 550 into a quad core plus shows it overlocking to 3.7ghz. Not bad for a $99 cpu :)

motherboards and bios version that allow for unlocking - http://www.overclock.net/amd-cpus/535501-amd-phenom-ii-core-unlocking-guide.html

  • But do you know WHY they disable these cores?

    They have faults in manufacturing.

    They intended to make a quad-core, but one or more cores had a fault and they recycled it by disabling these faulty cores.

  • @almann1117 Doesn't seem to faulty - I've since passed this cpu over to a friend who's been running it unlocked for over a year and it's still going strong..... It seems to be one of those things that either work or don't work and if it works it's stable.

  • @almann1117 Because they would rather make the quick buck by selling the CPU at a cheaper rate than to lose the buy just because the customer might not want a quad core and he might not even want to unlock it. They make these CPUs for around 10 bucks each, if even. They're making more than enough profit.

  • @Orangesplaywith How does that make sense financially?

  • @Cruising270 You get a higher chance for error; they could have also thought there was a chance of failure in the future. I'm glad you've saved money though :)

  • Hey I have phenom ii 550 the same as you but my motherboard resist only 140wats and when i changed the processor in bios i got 4 cores but i also got 158wats and its too much for motherboard. I didn't have any problems. You think it's dangerous to leave 158wats?

  • @almann1117 That's ONE of the reasons why they lock those cores.

    Another reason why they lock the cores is due to demand, when they need duel cores because people want them (due to the lower price) they'll simply lock the other two perfectly fine cores.

  • Hi guys, i've Asrock 770extreme3 mb, with phenom II x2 550 black, my chances are high?:D

  • @Girsheliz no since the 240 is a native dual core (i have it my self OCed to 3.5ghz)
