I have 2 theories.
1. Power supply. As an electrical engineer, I understand electronics will last longer with a more continuous, clean flow of electric current under load and spikes. That requires both a good power supply and a good motherboard that is not skimpy on capacitors. My $350 EVGA mobo is designed for that and is powered by PC Power&Cooling one of the best power supply companies out there. I even receive a technical printout of the actual test from the factory when I got my power supply.
2. Ambient temperature. Although this is just speculation, a 70 degree room vs. a 85 degree room makes a difference I believe in how much you can overclock stable due to all the transfer of heat to the actual GPU themselve. Higher lock, higher temperature.
Well my GPU is definitely outdated, I've had it for around 5 years. It's a Coolermaster Real Power 850w. I don't think it's the problem though as I have no instability issues what so ever with my system, this specific card just doesn't OC well at stock voltage.
My ambient is warm for sure, I live in AZ and the last couple days have been hot. Thermometer is reading 78 degrees, but that's in the hallway and it's quite a bit warmer in my computer room. Either way though, I'm on water and temps never even get above 50 degrees.
I will probably just need to give my card some voltage if I want to do any real overclocking
edit: Room temp in Fahrenheit, card temps in Celcius. Us crazy americans!!Edited by sublimejhn - 4/3/11 at 3:28am
