460m Bus is: PCI-E 2.0 x16 @x8 2.0

So I found out it is x8 instead of going x16. Is there something wrong with that???

I know the speed is negligible while gaming, but I was wondering if it was normal for the gpu to behave that way, and if there's a way to fix it.

Thanks

 

Should be x16, so something is wrong.

 

mine jumps for x16 1.1 to x16 2.0 depending on load, but that is all I have seen change

 

Well it doesn't feel slow at all, but it sure is different. What could I do to try to bring it to x16?

 

i have the same issue with 6770m in a hp laptop havok did you found solution?

 

Some programs can report bus speed incorrectly when not being stressed. As a power saving method, the bus speed can be reduced, but when stressed will return back to full speed.

 

Are you getting this reading for the bus speed in GPU-Z? If so, which version? If your aren't noticing any performance drops then it's probably just a software reporting error. I started a thread about this just recently because I was getting the same error on my G73JH.

 

I've tried versions 0.5.1, 0.5.9 and 0.6.0. They all show the same...

Do you have any kind of problems while gaming or idling, such as "Display driver <your-driver> stopped responding and has successfully recovered." ?

Cos I used to have a lot of them on certain nvidia drivers, tho they have been fixed (it happens now once every 50 reboots or so xD)

 

Maybe you should run a benchmark and see if your performance has actually decreased, although I suspect that this is just a reporting error.

I've gotten the "display driver has stopped responding and has successfully recovered" on my Radeon 5870 only when I had overclocked it too far. My games would crash to desktop and I would get that message. At a stable OC or stock clocks, I've never gotten that error.

 

My performance is as good as ever, but sometimes the error pops out. I've googled this problem and it seems to be driver related, and nvidia still hasn't fixed this.

 

Yeah not a big deal then unless you're really OCD about that sort of thing. My bus speed readings have changed over time too as I've updated my video drivers and GPU-Z, but the most important thing is that the performance has remained constant or even improved.

 

Well I suffer from OCD tbh, but well, there are things you got to learn to live with =/

 

Don't worry everyone gets that at one point or another.

 

i used to have the same problem but it was driver related i am talkin about the driver stopped responding etc..as for the first one pci e 2.0x16@x8 2.0 it is shown in every programm like pcwizard aida64 gpu z cpu z..is there a fix on that or it is just the way it is...

 

How did you fix your problem?

Im running 266.58 nvidia drivers now to prevent those issues and it seems to be working all right, but I would really like to run the latest ones for the performance increase in skyrim since I bought it a couple of weeks ago

 

i didn't fix it amd did..i don't know what skyrim needs but try put nvidia new drivers in many ways as possible i mean first try to put them on the former drivers if it doesn't work then try again with clean installation i hope it works and try the last four drivers if that doesn't work be patient and i really believe nvidia fix it..also there is another solution format but use it when you have no more patience..i really understand you because i have lost files important to me that way so i know how bad you are feeling..as for the pci e x8 does it have any real difference?

 

It is ok, as I said I have already fixed it, but not by upgrading drivers, I'm literally using drivers from past year. This drivers give no problems at all (from what I've seen).

 

With a card that slow, you won't notice any performance difference. It was noted that there was a 5% difference between a GTX 480 @ x16 vs x4 on the PCI-e bus. You won't notice anything since 5% on a GTX 460M means like... 1fps difference... big deal.

It's fine.

 

Sarcasm detected xD

 

ok and does anyone know pci e x8 2.0 what is the link data speed in gb/s?

 

Seriously? You're using old drivers just to see a different number in GPU-z? You realize that means worse performance, right?

 

I agree. If you can't use the newest drivers and have to use something from a year ago you may have something more sinister going on or need to update other drivers. Maybe try uninstalling Forceware through Control Panel, running Driver Sweeper in safe mode and removing all traces, then reinstalling the newest ones? Using the newest drivers are really important, especially if you play the newest games on the market because only the most recent drivers have fixes specifically targeted to those games, not to mention that you'll get sometimes vast performance increases.

 

I've done that with 8 different drivers already. With the drivers I'm using I prevent the issues of TDR's every 10 minutes and screen blackouts. Some drivers gave me a 5min black screen every boot up, then they ran perfectly. With these drivers (266.58) I get no problems at all...

I would never sacrifice performance for something as simple as a number in GPU Z ....

 

Since noone else is experiencing these problems, it's safe to assume it's not the driver's fault, but rather your setup's. I'd suggest a fresh reinstall of Windows.
