Voltage dip causes artifacting and restartingIsolated issues with some GeForce 8800GTX graphics cards have forced NVIDIA to stop shipment on some launch cards
A memo published by NVIDIA has circulated through GeForce 8800GTX launch partners claiming some initial G80 cards have been stopped from reaching resellers. Parts of this memo were republished on Bit-Tech earlier today. Specifically, the memo states that some vendor (including EVGA) GeForce 8800GTX based cards will generate artifacts and cause the system to restart after 30 minutes to 2 hours of operation.
Other manufacturers are also affected, but EVGA was specifically mentioned as having this problem. Any manufacturer shipping cards based on the NVIDIA reference design is not affected.
The artifacts and crashing are a result of an incorrect resistor value. According to the document, a 50K ohm resistor was installed instead of a 30K ohm and results in artifacts during heavy operation. Nevertheless, the document recommends checking the MOSFET to ensure the proper ones were installed and replace them if necessary.
EVGA has released a statement to DailyTech claiming "EVGA has been working very closely with NVIDIA to correct an error in an early BOM list for internal testing, sample boards and a few review units. There is no issue with production boards and this will not delay the launch."
Several other manufacturers, including XFX and ASUS, have confirmed to DailyTech that their GeForce 8800GTX cards are unaffected and will ship at launch without problem.
DailyTech previously explored the performance of NVIDIA’s upcoming G80 GeForce 8800GTX. The card used did not exhibit artifact or restarting issues.
