DFI CS61-EC i815EP SOCKET 370
Thursday, March 01, 2001
Introduction
Well, it seems that it's DFI's turn to present us with a new board, and so they have with the CS61-EC - a board based on the more & more popular (at least to manufacturers) Intel 815EP chipset. Not all i815EP boards are created equal however; some are designed with Overclocking in mind, others tend to be aimed for pre-assembled systems. With that in mind, let's take a look at the DFI CS61-EC, and see how it comes across.

Configuration
Configuration of the DFI CS61-EC is accomplished, for the most part, from within the BIOS.
On the board itself, there are only two jumpers to be found - J2, and J3 - which can be used to force the FSB to operate at 66Mhz, 100Mhz, or 133Mhz.
Its also possible to set the FSB frequency from within the BIOS, with settings including: 66/68/75/78/80/84/88/92/96/100/105/110/114/117/122/127/129/133/140/144/146/150, and 157MHz,
The processor's clock multiplier can also be set to a value ranging from 3X to 8X.
Unfortunately, it is not possible to manually adjust the Vcore or Vio voltages - these settings are determined automatically by the system.
Finally, the CS61-EC possesses an independent memory bus, with can be set to operate at 100MHz, 133MHz, or set on auto, at which point the operating frequency is determined by the system.
