Hello Forum members,

I am aware that Tom's Hardware has nothing to do with 3DMark however, this is one of my favorite forums as everyone is so nice here so if someone knows how to help me or knows where I can get better help please tell me.

I recently just purchased a copy of 3DMark on steam and I am trying to run the Ultra benchmark however my results keep coming up invalid. If I don't Overclock my GPU (GTX 980) the score appears valid (however much lower) but as soon as I use MSI Afterburner to Overclock my GPU by the slightest bit (even just a core overclock of +1Mhz) I get two errors, Graphics Card is not recognized and Graphics Driver is not approved (I am running on 344.75 the recommended driver for 3DMark). I am also running on the windows 10 beta however I am pretty sure that this is not the problem as the results are fine when I don't overclock. Does anyone know why this is happening or know a way that I can fix this because I really want to have my scores validated.

System Specs:
Processor: Intel Xeon Processor E3-1230 v3
Graphics Card: NVIDIA GeForce GTX 980 (Gigabyte)
OS: Windows 10 Preview

Results pages:
Non-Overclocked GPU: http://www.3dmark.com/fs/3662729
Overclocked GPU with error: http://www.3dmark.com/fs/3662682

Thanks, I would really appreciate it if someone could help me out with this.
