Different overclocking values?

[mistermaximal]

Hello LTT community!

Today, I tried overclocking my GTX970 for the first time (Model: Asus GTX970-DC2OC-4GD5-BLACK) and I was wondering why the Mhz and other values are inconsistent.

On the Asus GPU Tweak software, I set my GPU Boost Clock to 1400MHz (+147) and let the voltage sit at stock (1175mV).

When running FurMark, the GPU Monitor shows a clock of 1475MHz and a voltage of 1212mV.

When running the Firestrike Benchmark, it tells me my GPU had a Core Clock if 1261MHz.

 

I tried different clockspeeds and when changing the offset, it also changed on the other values (e.g. when lowering the offset by 20MHz, the other two values also went down 20 MHz)

Can anyone explain why it shows me these different values? Thanks!

Come on, anyone have an idea? Or at least tell me which one should be the actual clockspeed

Maybe because your not supplying enough power to the gpu?

GPU Boost does weird stuff like that. I'd trust the clock you're getting in Furmark, since that's generally more demanding than most other things.

 

GPU Boost will only push it as far as it needs to for whatever it's doing. Usually. Well, most of the time.

It really is screwed.
