"Stabilize" factory OC'ed GTX 660 Ti (3 GB)

Hey there!

Background:

My GPU (ASUS GTX 660 Ti DirectCU II OC 3 GB) is prone to random and infrequent TDRs (it might happen three times a day, it might not happen 4 days in a row) both in 2D (streaming YouTube videos) and 3D mode (games and other 3D applications) - but never when the card is idle - with every driver version above 347.88. In fact, I've been running my system with 347.88 for over two years without a single TDR in sight. But each and every time I try to update to a recent driver - they're back; which leads me to believe that it's not caused by faulty hardware.

I've tried more "solutions" and workarounds over the last months than I care to list here, all to no avail. My last hope is a theory I stumbled upon in forum posts like this in which the author suspects poorly optimized/too aggressive voltage tables of factory overclocked cards as the culprit and claims to have fixed his by flashing a modified BIOS with an adjusted voltage table.

Unfortunately, the author does not provide further details about the adjustments, so my question is: How would one go about this? I've already familiarized myself with Kepler BIOS Tweaker and nvFlash but with the risk of bricking the card, I'm a bit hesitant to do any experiments.

Any help would be much appreciated! If any further information is needed (screenshots, system readings, stock BIOS, etc.), I'll do my best to provide whatever I can.

Thanks in advance!
