How to choose SGM8304 operational amplifier module correctly?

The SGM8304 operational amplifier module level conversion board is suitable for Antminer S19kpro, T21, S19XP, and S21 hash boards. It can quickly amplify the hash board signal voltage, and with its high gain and frequency compensation design, it improves miner efficiency and mining capabilities. The original and replica SGM8304 Op-Amp modules are produced and used differently. The following will explore their differences in detail.

I. Appearance details

1. The difference between number codes

• The digital code on the back of each original SGM8304 operational amplifier module is independent. The manufacturer sets this code for purposes such as product traceability and quality control. The form and content of the code adhere to strict standards.

• Replicas of the SGM8304 Op-Amp module are divided into two types: non-coded and those with identical digital codes. The identical digital codes are used because different manufacturers or batches use different templates. Then they are replicated and produced according to a template without independent codes.

2. Silkscreen and materials

• The silk screen of the original module has a three-dimensional effect. The official material standards are strictly followed during production, and the materials are carefully selected to ensure good performance. Its surface is smooth, the color is uniform, the pins are bright, there are no signs of oxidation, and the production process is exquisite.

• Replicas are mostly made of ordinary materials, the silk screen and appearance are relatively rough, and there is a problem of uneven color.

II. Performance

1. Stability

• The original SGM8304 op-amp module is designed for official machines and has been verified by many actual applications. It has been strictly tested and optimized during the design and production process and can maintain high stability during long-term operation.

• Although the replica lacks strict standards in the design and production links, it can also achieve relatively stable operation in actual use scenarios.

2. Impact on hash rate

• The original op-amp module provides precise and stable signal amplification for the hash board. Under normal operating conditions, it ensures the hash board delivers optimal performance and maintains a high-efficiency hash rate output.

• The replica can also function stably and maintain stable signal output.

III. Other considerations

1. High-quality original SGM8304 op-amp modules are priced higher than replicas and undergo rigorous inspection before shipment to ensure no issues arise. Prioritizing original modules is recommended to maintain efficient miner operation.

2. Although the replicas we sell are slightly inferior to the originals in silk screen printing and some performance, all products will be strictly tested before shipment, which will not affect normal use. They are also affordable and suitable for users with limited budgets and no demanding performance requirements.
