DDR Introduction

Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a high performance and cost-effective solution that allows easy adoption for memoryvendors, OEMs and system integrators.

DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR memory (DDR266) doubles the datarate through reading and writing atboth the rising and falling edge of the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM clock frequency. With peak bandwidth of2.664GB per second, DDR memoryenables system OEMs to build high performance and low latency DRAM subsystems that are suitable for servers, workstations, high- end PC's and value desktop SMA systems. With a core voltage of only 2.5 Volts compared to conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops andnotebookapplications.

GA-7VAC specifications

The Gigabyte GA-7VAC is a feature-rich motherboard designed to accommodate the needs of enthusiasts and gamers alike. Launched during the early 2000s, this ATX motherboard was built to support the AMD Athlon processors, particularly those utilizing the Socket A interface. It became popular during a time when the demand for robust and reliable computing platforms was on the rise, thanks to the growing popularity of 3D gaming and multimedia applications.

One of the standout features of the GA-7VAC is its chipset, which is based on the VIA KT266 chipset. This chipset provides improved performance and stability, allowing users to enjoy faster data transfer rates and better memory management. The motherboard supports DDR266 RAM, with a total capacity of up to 2GB across its two DIMM slots. This capability ensures that the GA-7VAC can handle memory-intensive applications and multitasking with ease.

In terms of connectivity, the GA-7VAC is equipped with an array of ports. It includes five PCI slots, enabling the installation of various expansion cards, including graphics cards, sound cards, and network adapters. The integrated VIA Apollo 8235 Southbridge chip provides support for both IDE and USB devices, facilitating seamless connections to hard drives, optical drives, and peripherals. Users can also take advantage of the motherboard's integrated audio capabilities, which deliver quality sound without the need for additional sound cards.

Another notable characteristic of the GA-7VAC is its support for overclocking. With features such as adjustable front-side bus speeds, users have the opportunity to enhance processor performance beyond stock settings, allowing for a more customized computing experience. However, it is essential to ensure adequate cooling when overclocking, as increased performance can lead to higher heat output.

In conclusion, the Gigabyte GA-7VAC is a highly capable motherboard that caters to the needs of gamers and tech enthusiasts. With its robust chipset, versatile memory support, abundant expansion options, and overclocking capabilities, it represents a solid choice for those looking to build a reliable and high-performance computing system. Despite being an older model in today's market, its foundational technologies continue to appeal to users seeking a balance between performance and value.
