🖥️ Overview of the R9 295x2 PCB

The R9 295x2 is a dual GPU card that boasts one of the most complex printed circuit boards (PCB) in the market. With multiple voltage regulator modules (VRMs), this PCB is a marvel of engineering. In this article, we will delve into the intricacies of the R9 295x2 PCB, its VRMs, power throughput, and the possibility of volt modding. So, let's take a closer look at this beast of a PCB!

Understanding the VRMs

🔌 Core Voltage

The R9 295x2 relies on a four-phase VRM to supply power to each GPU core. This VRM, controlled by the NCP81022 voltage controller, ensures stability and efficiency. Although the VRM is robust, pushing high core voltages can pose risks due to heat generation and potential damage to the high-side FETs. Knowing the safe operating parameters is crucial to avoid any complications.

💾 Memory Voltage

The R9 295x2 requires separate voltage regulation for its memory. While there are indications of VRMs responsible for memory voltage, deciphering their specific functionalities is challenging without physical access to the card. However, it is advisable not to tamper with memory voltage unless certain about the VRM responsible.

⚡ Auxiliary and Point Nine Five Volt Rail

The auxiliary voltage, often overlooked in terms of overclocking, plays a role in supporting various GPU functions. The point nine five volt rail, designed for display-related tasks, is critical for LN2 usage and higher core voltage scenarios. Nevertheless, overclockers should exercise caution while tampering with these voltages, as improper adjustments may harm the card.

Power Throughput and Limitations

The R9 295x2's power throughput is a balance between its impressive capabilities and limitations. While the card's two eight-pin connectors may raise eyebrows in terms of power delivery, it is essential to understand their capacity. In this section, we will explore the power capabilities of the R9 295x2 and shed light on why two eight-pin connectors are sufficient.

Volt Modding the R9 295x2

Volt modding, a popular practice among overclocking enthusiasts, is a way to gain more control over the card's voltage settings. However, due to the complexity of the R9 295x2 PCB, volt modding this particular model may prove challenging. We will discuss the potential modifications one can make and the precautions to consider before attempting any changes.

BIOS Chips and Dual BIOS Function

The R9 295x2 comes equipped with dual BIOS functionality, enabling the user to switch between different BIOS configurations. We will explore the purpose and significance of these BIOS chips and how they contribute to the overall performance of the card.

Exploring the Eight-Pin Connectors

Many wonder how a card with only two eight-pin connectors can handle a 500-watt TDP. In this section, we will address this question and explain the true power capabilities of the eight-pin connectors. Understanding the intricacies of power delivery is essential for users looking to overclock or push the limits of their R9 295x2.
