This is probably the most useful post along the 10 pages in the entire thread. It should be pinned to the top.Igor has published a new in-depth analysis of the supply chain and quality control mechanisms regarding the issues with the vapor chamber.
Unfortunately it is only available in German: https://www.igorslab.de/einzelfaell...x-7900-xtx-kuehler-problem-samt-qm-qa-und-qc/
Here is ashortrather long summary:
- The whole card is manufactured by PC Partner, the cooler is made by Cooler Master, the vapor chamber is supplied by AVC (Asia Vital Components).
- As we all know by now the issue is caused by too little liquid in the vapor chamber. As far as Igor knows one charge of vapor chambers from AVC was affected which usually consists of 10000 units.
- Not all vapor chambers from that charge are fully defective, some work ok-ish, some show the 110°C issue.
- This slipped through quality control at Cooler Master and PC Partner which casts a damning light on their quality processes.
- To make matters worse vapor chambers and coolers are not serial number matched. That means the defective charge of 10000 vapor chambers is split among several charges of coolers and was mixed with non-defective charges.
- This means AMD has no way to match the serial numbers of the cards with the defective coolers, they can not issue a list of defective cards and the customer has to find out by himself.
- The amount of cards affected is quite high, AIBs (like Saphhire and Power Color) report ~10% of RMAs of their cards.
- At the beginning AMD support offered replacements within 2 weeks, now they say they can not provide a delivery date as their shelves are empty and rather propose a refund. This might be worsened by the problem that they themselves do not know which cards are affected and do not want to ship out another faulty card to an already unsatisfied customer.
- For us end consumers this is annoying, for the bigger system integrators who build hundreds of systems this is a real problem since they now sit on unfinished PCs they can not sell.
I wonder where der8auer is now to tell us that it's all crap and AMD hates everyone.
