Default Memory Clock on my 680m seems horribly wrong

My default clocks are 719Mhz and 900MHz for the GPU clock and memory clock respectively.

Every review I've read says that the 680m is at 1800MHz. Is there something wrong with my card? I have been getting way worse performance than I had expected with this unit so this would explain that if so.

I originally ordered a laptop with a 7970m but the vendor sent me a 680m by accident. Would this have anything to do with it? Should I check to see if I have the wrong bios installed or anything?

EDIT: Ooops, meant this to be in the hardware section. Any chance a mod can move this thread?

 

The reading you get depends on the application. Some applications such as GPU-z reads GDDR5 memory as dual data rate, so on a GTX 680M it would probably give you 1800 MHz. 900 MHz would be correct as well if you refer to it as a single channel speed. Either ways, both readings will equal to 3600 MHz memory clock speed.

On the note of getting the GTX 680M instead of the 7970M, congratulations and I would not even exchange it. You ended up with the more powerful and expensive card.

 

Oh I know I'm definitely lucky - especially as it will increase the resale value of my laptop tremendously.

Still, I'm having poor performance on a bunch of titles (SC2: HoTS, DOTA 2 and a few other's I can't remember) and it hasn't quite been the experience I was expecting. Still much, MUCH better than my old 285m, but I always see people getting much better performance out of titles with their 680m at stock clocks. Makes me constantly worry that something is wrong with mine.

 

Interesting. A few things I would check:

- Make sure you are not gaming off the battery. Your system needs to be plugged in for optimal performance; playing on the battery will cause the CPU and GPU to downclock massively and give poor performance.
- Update the nVidia driver with the latest WHQL from the nVidia website.
- In Windows power profile, ensure it is not set to Battery Saver. Ideally you need to be on Balanced or Maximum Performance.

 

Yeah, done all that already. Still no luck.

It's really annoying that DOTA 2 and HoTS always run at 40% GPU utilization so I can't get a smooth 60FPS. Not sure if that's an issue with the games, drivers or my rig.

 

your 680m is the 2GB version, which is weaker than the 4GB version that Clove has.
neither way, there seems to be an underutilization issue with it. HoTS doesn't really require high amount of GPU raw power but more dependent on CPU.
I will come back in an hour or two to see if my 680m 4GB version has a low GPU utilization on HoTS

And if you plan to get 60fps for multiplayer, it is impossible to get 60fps in late game. Even desktop 4.4 ghz cpu cannot run ZvZ late game full supply at smooth 30fps)

Just checked, I got full gpu utilisation for HoTS, so not too sure why it happens to you

 

Less vram doesn't mean it's weaker. It's the same card. If it were weaker, the M18x wouldn't be highest benchmarking laptop out there; the P370EM would be.

 

With it's lazy cooling design the p370 has no hope of getting anywhere near the m18x.

Can't believe people still think more ram means more speed. lol That's only true when the card runs out of ram which is quite unlikely at 1080p.

 

So true. It's very difficult to consume 2GB of vram at 1080p unless you are using ungodly texture sizes and a large amount of multisampling. Almost all today's games played at a sane level of "ultra" settings will be fine with 2GB at 1080p.
