[Solved] - Why is this Asus GTX 670 Mini throttling?

post #1 of 4
Thread Starter 
According to afterburner, the throttling is caused by hitting the power target. I flashed the BIOS with a modified power target of 300% and ramped the fan all the way to 100% which keeps the temps bellow 65C and it's still throttling under Unigine Valley. Why is this?

PSU: TX850

Are you overclocking the card? And if so to what levels on the GPU and/or memory?

Well, I figured out the problem quite a while ago and thought I might as well share my findings. Basically, the board's power design is the problem.

Even though the PCB has a theoretical power limit of 225 watts (150 watts from the 8-pin PCI-E + 75 from PCI-E interface), in practice, it doesn't like anything more than 150 watts. In order to get a stable clock, I had to set the GPU voltage to 1.15 volts. Anything over that made in the core clock fluctuate all over the place, resulting in reduced benchmark scores and lower average FPS.

I'm pretty sure it's going to be the same story with the GTX 760 Mini. They are nice little cards but I wish that ASUS would have done a bit more work on the power delivery portion of the card.
