Covington right|thumb|180px|Intel Celeron Covington Launched in April 1998, the first Covington Celeron was essentially a 266 MHz Pentium II manufactured without any secondary cache at all. Covington also shared the 80523 product code of Deschutes. Although clocked at 266 or 300 MHz (frequencies 33 or 66 MHz higher than the desktop version of the Pentium w/MMX), the cacheless Celerons had trouble outcompeting the parts they were designed to replace. Substantial numbers were sold on first release, largely on the strength of the Intel name, but the Celeron quickly achieved a poor reputation both in the trade press and among computer professionals. The initial market interest faded rapidly in the face of its poor performance, and with sales at a very low level, Intel felt obliged to develop a substantially faster replacement as soon as possible. Nevertheless, the first Celerons were quite popular among some overclockers, for their flexible overclockability and reasonable price. Covington was only manufactured in Slot 1 SEPP format.
