GPU-Z Bus Interface

[.Griff.]

I've had my GTX480 for a couple of weeks and all seemed well until 10 minutes ago.

I just jumped into Bad Company 2 for a game and noticed that my FPS wasn't what it should be and as I hadn't restarted the PC for about a week (I leave it on 24/7) I decided to restart the PC.

I then opened GPU-Z to make sure the clock speeds were what they should be and it's then I noticed something.

The "Bus Interface" seems to be changing on it's own.

Compared to -

Is it a glitch with GPU-Z or something more serious?!?

It's normal it's downclocks when the system is idle. It will go back up when your gaming and is perfectly normal.

yes it's power saving and gets asked about every second day here on the forums

Oops. My bad. I started to panic and fear the worse.

Thanks for the replies.

What about when it's not changing? Mine never changes. No matter what. Stays at PCI-E 16x @ 16x. My previous 4 ATI cards were always 2.0 16x @ 16x 2.0.

if it dosnt change then it dosnt change... ???????

im lost as to what your question is...




of course it wont drop down if the power saving features are turned off...

i really wouldnt worry about it..... i highly doubt it has any significant power saving when it drops down.

No I'm saying it won't go up.

It does this even when running furmark in a Window?

While running anything.

dont feel bad, I rma'd my gt240 for the same reason. never thought to ask here. when I got the new one and it did the same thing I opened up furmark and watched it change back under load.

edit: wait so under any load it doesnt go back? did you check in bios to see what it set to. something autonomous switch or somthing like that

Thats odd, my GTX470 will still drop down to x16 @ x16, even with the power setting set to off, but will go up to x16 2.0 @ x16 2.0 when I run anything on the GPU.

I wouldn't worry too much about it though, it won't effect performance.

No 1.1/2.0 switch in the bios.

I also reseated it. Still not 2.0.
