Summary: Great laptop S1G4 cpu. The four cores at 2.3GHz provides plenty of power. However, its 45w TDP (shows up at slightly over 40w in HW monitor) makes your laptop cores run hot if you don't have adequate cooling. My medium sized laptop's x4 920 ran at ~60'C idle and 85'C load. However, I was able to undervolt by setting idle voltages at .70v to .75v and load volts at .95v to 1.0v.
Summary: When I received my Dell Inspiron M5010 there was something about the system that wasn't quite right. After much checking of system components and reinstalling software,I thought I'd figured that is was a software conflick that was causing the freezes and slow responses.Then after reading several forums decided that it was that the processor/ram combination might be the problem.
Unfortunately this review will help cause a scramble...

Summary: Well, we can keep this fairly straightforward...if you have a proprietary computer (ie: Compaq, Gateway, Dell, Hp...etc) this 920 and the 940 are the ONLY quad core chips that can be used in an AM2+ motherboard to upgrade to Phenom II (the discontinued tri core chips can be used too). If you build your own then you may obtain Bios updates to allow AM3 chips to run in A2+ boards and have many superior options (965, 955) to upgrade..
