Trying to get as much juice as I can from my GTX 660 ti while waiting for Volta to finally upgrade, but I'm afraid to overclock its memory because it has no themal pads. Not knowing memory temperature is quite frustrating for me because from testing I was able to reach more that 7000 MHz stable on it. Right now I have it at 6600 MHz but I'm worried I could be killing it, which I don't want, because I intend to sell it. I have googled and people don't seem to agree. Some say that video memory consumes little power, so just airflow from the fans is enough, but then, why do manufacturers put thermal pads on cards at all? There's even people who say heatsinks heat the memory rather than cooling it. What do you guys think?
