5-10% GPU performance degradation without heavy usage in 3 months?

Hi everyone, please help me out if you know something about this!

I bought a GTX980 Ti in January and of course I've done a lot of benchmarking back then to see how awesome it is. For more details, it is the MSI Twin Frozr model with highest "guaranteed" clock speed. Unfortunately I don't keep tabs about those benchmarks as much as I should, and at this point my ONLY reference is the saved 3D Mark record ran in January.

I haven't used it a lot because current job is very demanding, and I've ran more tests on it then use it to game. When I do game it's some online multiplayers which aren't the most demanding, although I do tend to leave my OC up whenever gaming.

Now in simply 4 months time. My GPU performance degraded 5-10% according to 3Dmark tests, and with the exact same OC (you can see my GPU clock speed, memory OC, in the screenshot below).

I ran multiple times to make sure it isn't a inconsistency issue, and they fluctuated a little bit but never got less than 5% decrease, and this is the worst run.

To make the result even more consistent. I had 3 OC settings, which push the performance to 3 different level, with all consistent degradation across the board. AKA at low OC, my current result is 5-10% worse than in January, so is mid OC, and at high OC. There isn't anything funky going on pushing it sofly or to its limit.

I honestly find it hard to believe this is natural, but I've tried as hard as I can to eliminate external factors. I have dual screens, but I'm positive I had the other screen on in my January test as well. I don't have any other weird apps running in the background, and quite honestly whatever that's going on now was going on back then. Therefore if I try to remove all of them it only makes it a worse comparison?

The only concerning factor that I want to address is that because I haven't benchmark in a long time, my initial plan wasn't to compare it to January, but to simply test its limit OC as I've heard G1s can easily do 1500MHz+, mine indeed could not and crashed hard at 1550MHz. It was after this I thought to do normal testing and compared them to old result.

I build and test computer for quite some time now, yet I never keep track of things very well so despite the experience I have no idea if that's something to be expected. As far as I used to know, a crash by barely pushing a GPU over its limit does little to no damage to the card; and I did this once. Also with my usage it's hard to see anything else causing this in this amount of time. I do OC it to play some not-even-demanding games quite a bit, but it is at a OC range where it's stable and never crashed.

All ears for what anyone think might be causing this?

I've fixed this problem and the cause is really stupid.

Apparently 3dMark went through some updates, so is Nvidia driver and a lot of other things... the point is, some configuration got messed up.

Usually when 3Dmark fires off a benchmarking it would turn off the other monitor if you have one. I don't know where the settings are for that but it's the default for me. But due to some mis-configuration this was not the case when I ran the tests recently which made me make the post. I'm not sure exactly what made it so, but at the time I had Shadow Play running as well as a bugged out Nvidia Geforce Experience (like I can't even open it and had to reinstall it).

I had no memory of this being the default, and knowing that I never personally tweaked any settings, I assumed the default has to be the same back then vs now.

Later I updated my Nvidia drivers and fixed those other issues, turned off shadow play and tried again. As soon as I started the benchmark 3dmark turned off my 2nd screen and I'm like "is this how it's suppose to be?" The final results are almost identical to my original values back in January. So I can only assume this is exactly what caused the difference. And not that my GPU degraded just the right amount to have the same value as before with another screen on.

Eh another stupid post but things happen :p
