The Quest for a GTX 680 FTW

In today's article, we will be diving into the world of graphics cards as we explore the disassembly process of a GTX 680. This particular card has been on the author's wishlist for quite some time, and finally, the opportunity arose to acquire one on eBay. However, finding the perfect GTX 680 with the desired specifications was no easy task. The author was determined to find a four-gig FTW version that possessed a superior PCB, as the reference GTX 680 PCB was notorious for its inefficiency. After careful consideration, the author settled on the FTW variant, as it offered the desired specifications without the exorbitant price tag associated with the classified versions.

Disassembly of the GTX 680

Upon receiving the GTX 680, the author was eager to embark on the disassembly process and explore the inner workings of the graphics card. The initial inspection revealed a card that was dusty and in need of a thorough cleaning. As the disassembly progressed, the author discovered interesting features, such as the textured design on the heatsink and the surprising presence of a vapor chamber cooler. While a blower-style cooler would typically be disregarded for its lackluster performance, the author couldn't help but appreciate the aesthetics it brought to the card. Despite the initial assumptions, the GTX 680's power consumption was relatively moderate compared to newer models.

Examining the PCB and Components

As the disassembly continued, the author meticulously observed the GTX 680's PCB and its associated components. The FTW variant showcased an impressive PCB layout, reminiscent of the renowned classified versions. The author noted the presence of an eight-phase Vcore voltage regulator module (VRM), which, although not as robust as the 14-phase version found in the classified models, was more than sufficient for powering a GTX 680 core. Additionally, the author discovered a three-phase memory power section, a substantial upgrade over the reference GTX 680 design. The memory chips, supplied by Samsung, were arranged in a clamshell configuration, effectively doubling the memory density.

Understanding the Memory Configuration

Delving deeper into the memory configuration, the author explained the unique approach taken with GDDR memory. Unlike other memory types, which utilize ranks for increased performance, GDDR memory excels at increasing capacity. By reconfiguring each chip from a typical 32-bit wide interface to a 16-bit configuration, manufacturers can effectively double the memory capacity without compromising performance. This approach offers advantages for memory-intensive tasks and provides scope for future expansion.

Upgraded Output Filtering

Compared to the reference GTX 680, the FTW variant boasted an upgraded output filtering system. This improvement resulted in cleaner power delivery and minimized potential interference. The author highlighted the importance of such enhancements, as every improvement over the reference design contributes to overall performance and stability.

Thermal Pad Considerations

One crucial aspect of disassembling and reassembling graphics cards is the proper utilization of thermal pads. The author stressed the importance of using the correct thickness for optimal cooling performance. Incorrect thermal pad thickness can lead to warping of the PCB and even component failure. To ensure accuracy, the author used calipers to measure the thickness of the thermal pads and marked the measurements on the respective components.

Cleaning and Reassembling the Card

With the disassembly completed, the author proceeded to clean the GTX 680 and prepare it for reassembly. The dusty and sticky nature of the card prompted a thorough cleaning process, ensuring that all components were free from debris. The author also took the opportunity to replace any corroded or unsightly screws, aiming for a pristine and restored appearance. Proper reassembly was crucial to maintaining the card's performance and aesthetics.
