Editing Celeron (section)

== Dual-processor support ==
As a budget processor, the Celeron does not support a [[Multiprocessing|dual-processor]] configuration using multiple CPU sockets, however it has been discovered that multiprocessing could be enabled on Slot 1 Celeron processors by connecting a pin on the CPU core to a contact on the processor card's connector.<ref>{{cite web|url=http://kikumaru.w-w.ne.jp/pc/celeron/index_e.html|title=The Dual Celeron System|last=Kawada|first=Tomohiro|url-status=dead|archive-url=https://web.archive.org/web/20010210013824/http://kikumaru.w-w.ne.jp/pc/celeron/index_e.html|archive-date=February 10, 2001|access-date=November 1, 2009}}</ref> In addition, Mendocino Socket 370 processors can use multiprocessing when used on specific dual Slot 1 motherboards by using a slot adapter.{{Citation needed|date=August 2013}}
The unofficial SMP support was removed in the Coppermine Celerons, and dual-socket support is now limited to higher-end Xeon server-class processors. Conroe/Allendale based Celeron processors and later support multiprocessing using [[multi-core]] chips, but are still limited to one socket.

The [[ABIT BP6]] motherboard also allows two Mendocino Socket 370 Celeron processors to operate in a [[symmetric multiprocessing]] (SMP) configuration without any modification to the CPUs or the motherboard.
