If you go here
' ">http://www.xbitlabs.com/articl...ay/sempron-2600_2.html you will see that almost everything is disabled on Sempron for socket 754 compared to Athlon64. Just the "older" 3100+ have other features then the rest.
The reason for not have CnQ enabled are that it is allready on the lower side of clock (1600 or 1800) and don't get that warm (69 watt) as Athlon can get under load. If Greyhounds information are right, then Sempron are built from mobile CPU and therefore also of a cooler design. See link above and to Greyhound for more information.
X-bit labs page are usefull if you want to know more about this group of Semprons.
