Recently, a large number of RTX 3080 and rtx3090 players reported that they often encounter black screen, overclocking and even serious crash problems in the game, which may be related to the type and number of capacitors used by the chip on the back of the graphics card.
What are the causes of rtx3080 / 3090 frequent crashes?
Nvidia chose the MLCC POSCAP scheme when determining the chip capacitance scheme, in which the MLCC is ceramic laminated capacitance and the POSCAP is tantalum polymer capacitance. For example, the common version RTX 3080 graphics card adopts 20 specifications of MLCC 4 POSCAP. The MLCC is that the number of ceramic laminated capacitors is related to the stability. If a single POSCAP capacitor is selected, the overclocking performance and stability will be poor, and the video card will crash.
How to choose the capacitance of video card?
After the assiduous research and development and testing of ASUS engineers, the full MLCC capacitor is used in ASUS 30 series video card capacitor. ASUS independent power R & D team found that the design of full MLCC capacitor can better pass the practical application test and greatly increase the stability, so it made a capacitor design scheme like this.
High cost of fittings
The full MLCC array used in the 30 series video card is 6 groups, with 60 array points in total, while the poscap scheme only needs 6 array points. Because the manufacturing industry's cost calculation method is based on the number of points, which can be simply understood as the cost of one piece, the installation cost of full MLCC array is much higher than that of poscap in terms of production cost.
As we all know, there must be losses caused by production errors in the production process. Asustek uses the full MLCC array graphics card, and the times of placing parts are 10 times higher than that of poscap scheme. For example, for the same production of 100000 graphics cards, using MLCC array graphics cards requires 6 million MLCC, with 6 million pieces of parts; while poscap scheme only has 600000 pieces, with 600000 pieces. Obviously, the number of repair and scrap caused by factory error will increase a lot when using MLCC array, which also increases the production cost and difficulty of graphics card.
Only fully automated process can produce MLCC reliably
But asus's pursuit of graphics technology will not be limited by production costs. The guarantee of ASUS quality is embodied in the production of graphics cards. Even if the cost of full MLCC array is significantly higher than that of poscap, ASUS will also choose components that are more conducive to the quality and performance of graphics cards, and launch high-performance and high stability products that players can rest assured to buy.
Why does ASUS dare to adopt full MLCC array scheme? This has something to do with ASUS's unique fully automated production, because only the automated process can effectively and reliably produce MLCC arrays. Full automatic production avoids the dip wave soldering process which must be used in manual production, and also avoids the brushing and washing process that must be carried out after the wave soldering process.
The inevitable damage of PCB in manual production
It is fatal to wash the MLCC array by hand. It is impossible to control the washing force manually. It is very likely that the MLCC body will be seriously damaged or even directly torn down.

In addition, the cleaner used in the brushing process will dissolve part of the flux and flow into the MLCC array, which cannot be completely removed. The organic non neutral pollutants remain in the MLCC array for a long time. Especially in the high temperature and high humidity environment, it will lead to solder joint corrosion, mildew and other problems, resulting in reduced reliability and even direct damage and scrap of the graphics card.

The ASUS automation process technology has no dip wave soldering and does not need to go through the manual plate washing process, so it can boldly use the full MLCC array, which is the exclusive technical support of ASUS. Every ASUS video card solution is closely linked, in order to produce hardware products that the players are satisfied with and guarantee the quality.
Reliable brand makes a unique choice
Asus brand professional R & D, for product technology innovation drive, has always been only right, irrelevant price. Through its own strong R & D strength, constantly introduce more excellent hardware products, and through fully automated process technology to ensure the quality of graphics cards. For the quality of no compromise, only to create a higher performance Asus graphics card, the future will also use excellent PC solutions to meet the needs of various extreme applications, become the game hardware industry benchmark, continue to bring players
