According to our industry source, Diamond Multimedia has been aware of the problem, but decided to keep the faulty cards in the channel. We were told that all HD 3850 512 MB cards shipped between January and July are defective as well as a substantial number of HD 3870 512 MB cards and X2 models. All cards lack power management features; the 3850s were identified to have quality issues with poor soldering and integrated memory problems while the 3870s were delivered with a wrong resistor value, which can result in computers not starting up and system crashes.

The whole issue was amplified through a complaint by Alienware, which, according to sources, returned all graphics cards it had purchased from Diamond Multimedia. The system builder found failure rates of more than 10% with X2 cards, more than 2% with 3870 models and almost 8% for 3850 versions. Especially problematic were artifacts in common games as well as system crashes.

For Alienware, the issue was serious enough to scrap its business relationship with Diamond and replace it with another supplier. In total, Alienware returned more than 2600 graphics cards. In a previous instance, Alienware had found 100% of a supply of Diamond Multimedia graphics cards to be defective.

It is important to note that Diamond Multimedia was not the manufacturer of these graphics cards. A fair amount of vendors actually contracts other manufacturers to build their cards. Diamond works with companies such as Sapphire and Info-Tek Corporation (ITC). In this specific case, it was ITC, better known for its brand name GeCube. Companies such as Diamond Multimedia usually change the cards they receive to differentiate themselves from their competitors: The most common changes are BIOS modifications as well as GPU and memory overclocking. While researching this story, we found that an obvious suspicion was that Diamond may have applied some unusual changes, as similar problems did not Surface with 3800-series cards of other manufacturers. However, according to the information that is available to us, it appears that the errors were most likely caused due to manufacturing problems at ITC. Diamond may have received flawed cards from its contractor

מה שעצוב הוא שלפני כשנה קניתי 3850 של GECUBE :'(

[Nemesis]

זה לא אומר שה-GECube דפוקים.

התכנון והייצור של הכרטיסים יכול להיות שונה לחלוטין.

החברה הזאת בונה כרטיסים לחברות כמו Sapphire ו- Gecube.
