770 slight performance drop?

Anyone have an idea why this is happening?

Running benchmarks like MetroLL and 3dmark 11 would yield results on average of:

58.3FPS
11900

Now its at
57FPS
11700

Heaven and Valley has dropped too. Clocks and drivers were untouched. I dropped clocks down to same speeds as my other 770 and it was still slightly slower. GPU activity maxes out at 99% but is a bit jittery.

The thing is that I can clock the card further which heats it up more but still delivers more FPS so I doubt its throttling. That and besides I tested it during the night at 4am when it was colder. Temps never go above 66c. If its a driver issue how can performance differ whilst being on the same one. I've been monitoring boost clocks and its definitely not throttled.

There is a difference between throttling and running warmer, most computer parts will run better the cooler they are even though the differences might be tiny, throttling on the other hand is something controlled by your cards bios.

Before I watercooled my GPUs none of my cards throttled due to me keeping the fan profile high enough to prevent it, now the GPUs are under water they give even more performance as they are running a lot cooler.

I find the best time to test something on a PC is as soon as possible after it has started up first thing in the morning, before everything has had a change to heat up.

Thanks for your knowledge. I've ramped up the fan profile and MetroLL shot up to 60.81. Great stuff.

Edit: Nope I had the res incorrectly set to 1080p instead of 1200p. :(

The performance drop is insignificant but it might underlie a more serious problem with the card because I see no reason for this to happen other than some sort of defect.
