О: Наиболее вероятная причина - переразгон памяти. Так же проблема возникает из за нестабильного\недостаточного питание или производственного брака .
Последнее чаще всего наблюдается на разогнанных картах производства MSI .

For the HD6800 card AMD is using CHiL 8214 VR. This VR is used in multiple products and in different configurations. The chipset comes with a 00 default configuration, however the manufacturers have the option to write individual configurations for their graphic cards. When this happens 00 is substituted with a different number (in 8214 module’s case there are 18 configurations). These configurations have to be provided to CHiL (AMD, NV and the manufacturers are doing this) who in turn does the necessary modifications and the VR has to be ordered based on the modifications there on. The cause of the problem is that the cards in question have not been using the properly configured VR that in some cases caused voltage fluctuations which in turn caused no signal. Gigabyte manipulated memory timing through BIOS so the memory is more forgiving to voltage fluctuations, with positive results for some customers.
The problem came to surface because AMD’s main partners ordered a large number of CHiL 8214 configured for HD 6800 therefore creating a shortage for the rest of the manufacturers who are not partners. Most likely Gigabyte did not wait until the properly configured 8214 shipment arrived and used a similarly configured 8214. According to the information approximately 100 cards were built with these chipsets. Since there is no recall Gigabyte is probably waiting for individual warranty calls, also noting that other manufacturers could have the same problem, only because of a malfunctioning VR, simply a manufacturing defect. One can recognize this is a Gigabyte problem since their cards malfunction under similar applications for the majority of users versus other VR faulty customers where the freeze happens randomly if the load is slightly larger.

просьба доработать фак

Могу слить свой биос от HIS HD 6870

Конечно, есть возможность. Подключай кулер видеокарты к функциональной панели и вперёд.

По чёрному экрану дополнил FAQ , добавил инфу от Ty3uK_UA`а , лишние потёр .

RaymanRUSSIA У вас НЕ в этом ! проблема . Если монитор потух наглухо , то как вы на нём читаете сообщения о драйверах ... Ну хоть немного думать надо перед тем как писать .
Проверяйте другие компоненты системы, БП в первую очередь ! А карту желательно на другом компьютере .

Какую из этих 6850 порекомендуете: Sapphire, MSI Cyclone, Sapphire Toxic? И почему?

Sapphire Toxic
