DFI CS65 SC i815 Motherboard Review

DFI CS65 SC i815 Motherboard Review - PCSTATS
Abstract: The Intel i815 chipset can be considered as the true successor of the renowned Intel 440BX chipset. Starting from the 810, Intel has shifted its position from the standard north/south bridge design in favour of what they like to call Accelerated Hub Architecture, or AHA for short. Under this particular design, there are 3 individual hubs: the Graphics and Memory Controller Hub (GMCH), the I/O Controller Hub (ICH) and the Firmware Hub (FWH). The GMCH and the ICH are connected through an internal bus, which offers a bandwidth of 266MB/sec (twice as fast as the PCI).

Installation and Testing

The installation of the CS65 SC went along smoothly without hitches. The board can automatically detect the CPU type & FSB. Windows 98 installation went fine and all the necessary drivers were easy to install.

Testbed Setup

OEM Intel Celeron 566MHz FC PGA
Tested boards: DFI CS65 SC (Intel 815), Soyo 6BA+IV (Intel BX), Soyo 7VMA (VIA PM133), DFI CA64 EC (VIA Apollo Pro 133A with ATA 100 support)
128 MB PC 100 CAS 2 SDRAM
3dfx Voodoo5 5500 AGP
Western Digital 30GB ATA 66 hard drive, 5400 RPM
Orchid Nusound 3D (Aureal Vortex 1 sound card)
NEC 5500A DVD ROM (8x/40x)

The memory speed on the Soyo 6BA+IV was 66MHz as the Intel BX does not provide support for asynchronous memory/CPU FSB. The Soyo 7VMA was unstable when we used the HCLK+33MHZ (100MHz) BIOS memory option, so we had to stick with 66MHz. Our DFI CA64 EC board didn't have any option for asynchronous memory/CPU operation, so its memory access was also left at 66mhz. The only board that had a working 100MHz memory operation was the CS65 SC.

All BIOS settings were tweaked for maximum performance on all of the tested boards. On all of the tests we used the Orchid Nusound PCI soundcard for audio output instead of the integrated AC97 codec, unless noted otherwise.

Business Performance

The CS65 SC excels in the Content Creation Winstone 2000 performance suite. This was somewhat expected since the rest of boards were using a slower 66MHz memory bus (for reasons we previously explained). If the DFI CA64 EC and the Soyo 7VMA were running memory at 100MHz, they could have reached performance levels of the CS65 SC. Only the 6BA+IV, based on the powerful Intel BX, is capable of keeping up with the CS65 SC even though it uses 66MHz memory access.

The Business Winstone 99 performance of the CS65 SC was top notch. But this time, the performance differences are relatively smaller than those seen on Content Creation Winstone 2000.
