EVGA has discovered that some of the GTX 670 products (Superclocked model to be exact) are not working as they should. Apparently not every card was properly screened during QA/AC procedure. If you are the user of this particular model and you notice some problems, EVGA will replace it with GTX 670 ForTheWin version for free.
EVGA GTX 670 SC may cause BSOD’s, Desktop Freezing, Artifacting or won’t even load any benchmark/game.
You can learn details from this EVGA’s note :
The EVGA GeForce GTX 670 just launched, and we are all very excited about the great performance as you are aware. Some customers have just started receiving their cards and playing games on the new 600 series architecture.
On the forums we have noticed several users experiencing artifacting with the Superclocked version (02G-P4-2672-KR). We understand some users frustration about receiving a new product that is not working. Customer satisfaction is EVGA’s top priority and in order to ensure this, I have received special permission to those affected users above to offer an upgrade to the FTW model (02G-P4-2678-KR) with 2nd day cross shipping (in US). Replacement cards will begin processing Monday with shipments planned for Tuesday (5-15-2012).
This issue has already been escalated to top management, and is receiving top priority. We will update on this by Monday end of day.
If you have any concerns or issues with your GTX 670 Superclocked, please register your product and email our Product Manager, Jacob Freeman at firstname.lastname@example.org with your serial number and detailed issue.
