Keywords

💡Mineração (Mining)

The practice of using graphics cards to mine cryptocurrencies, which can age the components like the memory and GPU. The script discusses how mining may have been done with this particular graphics card, judging by visual signs of use.

💡Usada (Used)

The main finding of the analysis is that this graphics card, while sold as new, shows clear visual signs of prior use and repair work. Examples given include solder flux residue and darkened memory chips.

💡Garantia (Warranty)

An important consideration raised is that the vendor provides a 1-year warranty despite the used status, which may still offer consumer protection compared to unofficial imports.

💡Investigação (Investigation)

The script mentions how the channel focuses on repair, modification and investigation of electronics like graphics cards. The video represents this investigative process.

💡Autêntica (Genuine/Authentic)

The memory chips are confirmed to be authentic Samsung modules rather than counterfeits, based on the specific identifiers checked.

💡Cooler (Cooler)

The new/unused appearance of the graphics card cooler and packaging initially suggest it is new, but upon opening it is an older used model.

💡Remarcada (Relabeled)

The printed circuit board is identified to be a relabelled/remarked MSI model rather than original to the current branding.

💡Conserto (Repair)

Signs of repair work are pointed out, including re-soldering traces and cleaning flux residue, indicative of prior fault rework.

💡Reaproveitado (Salvaged/Reused)

The script concludes the specific graphics card was likely reused rather than assembled from salvaged parts, since the PCB, GPU and memory match rather than being mixed-and-matched.

💡Desempenho (Performance)

The expected gaming performance is clarified to be similar to an RX 570 rather than the advertised RX 580, since the GPU model is suited to the earlier card.

Highlights

The video is analyzing if an RX 580 graphics card sold as new is actually used

The GPU chip is from 2018, so the card is not brand new

There are signs of rework and corrosion on the PCB, indicating the card has been used

The memory chips are Samsung and have uniform date codes, they don't seem to be counterfeit

The solder on the memory channels doesn't look very good, evidence of prior use

Testing shows the memory chips are not painted/fake, they are authentic Samsung

The PCB layout matches an MSI RX 570 Armor card, this PCB has been rebranded

The conclusion is that while the cooler and box are new, the card itself has definitely been used before

The memory chips and GPU show signs of use but are still in reasonable condition

Ryan Mod should clarify in listings that these are used cards, not brand new

They offer a 1 year warranty so used is OK if disclosed, unlike cards from China

This RX 580 is actually an RX 570 or RX 470 with the BIOS modded for more performance

Considering the warranty, the card is fairly priced even if used, if condition is disclosed

Ryan Mod should remove "brand new" from listings and admit cards are reused to be transparent

This video aims to provide an honest analysis of the true condition of these cards
