Određeni primjerci Athlon II X4 600 serije nude mogućnost otključavanja 6MB L3 cachea

The latest in AMD's almost deliberate series of processors that unlock into powerful / more capable processors is the Athlon II X4. Some of the earliest batches of these sub-$150 quad-core processors can be converted to more powerful Phenom II X4 chips using a simple trick. When unlocked, the chip will be equipped with 6 MB L3 cache. Supposed to have been based on the "Propus" core that physically lack a L3 cache, apparently early batches continue to use the "Deneb" core with L3 cache locked (using moist threads instead of a padlock). Currently there's no information as to which specific batches of Athlon II X4 620 and Athlon II X4 630 work. The trick works on some motherboards that support the Advanced Clock Calibration (ACC) feature. Simply set the ACC option in the BIOS setup to "Auto" from its default value of "Disabled", and you're done.

Phenom II X3 740

It's been a long time coming, but AMD is finally going to add to the tri-core line-up (which is nothing but Phenom II X4 with one core disabled). The new product in question is Phenom II X3 740 - running at 3.0 GHz, with a total of 1.5 MB L2 + 6MB L3 cache. No word yet on the power envelope, but it could well remain at 95W—AMD does sell a quad-core, 95W Phenom II with that same clock speed, after all.
