PCIe 2.1 x16 @x2

[MrJets]

My video card is a PCI Express 2.1 x16, but it's running as PCI Express 2.0 x2. My motherboard says it supports PCIe 2.0(but doesn't specifically say 2.1) x16, but I find it hard to believe that would be the reason it's running @x2 and I can't get it to x16. I hope someone can help me.

Here's a screenshot of GPUz, if it helps.

What is the make and model of the motherboard?

 

[megamanx00]

Exactly what motherboard do you have? Could you have put it into a shorter 4x slot or something :O

 

[MrJets]

Sorry, forgot to mention that, the motherboard is ASUS M4A78T-E. My video card is in the first slot (PCIe 2.0 x16). I just looked up my video card online and it says 2.0 x16, this is starting to drive me crazy. I hope someone can help me out because as far as I can tell, this should be running at x16 not x2.

Edit: I just put my full system specs in my signature for further reference.

download gpu-z and post a screenshot
http://images.hardwarecanucks.com/image/mac/reviews/asus/M4A78T-E/M4A78TE_3.jpg

Check my first post for the gpu-z screenshot. Sorry but I'm not sure what that point of the diagram you posted is, all I know is that if you look up my motherboard http://usa.asus.com/product.aspx?P_ID=cf8IZzbU4m6GHKnW and check the specs it'll tell you it has 2 PCIe 2.0 x16 slots.

Thanks for the replies.

 

[MrJets]

Sorry didnt see the screenshot images was on cached for some reason. That image was just to get the details of your mobo up so that everyone can see the slots its got. Can you please run furmark or a benchmarking utility that will stress the gpu and run gpu-z again see if it stays the same

Please make sure your onboard graphics is disabled in the bios aswell

Alright, I ran furmark and unfortunately gpu-z stayed the same(I assume this was to test any power saving that might be happening). My onboard gfx is disabled, I did this yesterday hoping it would change something but it didn't.

Reseat the card, I had the same problem with my 6950 when I first installed it, the problem was caused by a little grease on the card edge connector, a light clean with isopropyl alcohol and a pen eraser resolved the issue.

 

[MrJets]

I cleaned the card connector, reseated it in the first slot with no change. Moved it to the second slot, no change. Thanks for helping me out, I hope someone has more suggestions, I'm willing to try anything.

HWiNFO gives a lot of different information, I've been looking through it for the past 15 minutes and I'm not sure what to post that will help but here goes:

Current Link Speed: 5.0 Gb/s
Device/Port Type: Legacy PCI Express Endpoint

Sorry the reseat did n't work...One can but try.
Something seems a litte odd, HWINFO is showing the current link speed as 5Gb/s, which is correct for PCI-E 2.0 at x16! Perhaps something is preventing the monitoring software from reporting the correct values.
Can you benchmark any games and compare your results with those from reviews of the HD5770? Your results may not be exactly the same but a big loss in framerates would at least rule out software errors.
Can you try the card in another machine?
Can you try another card in this machine?

Out of everything I looked at in HWiNFO, the max/current link speed both being the same struck me as odd which is why I posted it.

So I downloaded 3DMark Vantage and I'm comparing things to this http://www.tomshardware.com/reviews/radeon-hd-5770,2446-5.html

GPU Test Results:
Performance - 9033
High - 6261

Those scores are actually a bit higher than what is in the graphs, does this mean that it's running at x16 but software is seeing it as x2?

Once I get into the PCI Express Configuration, there is no option for Primary Video Controller or anything that you mention after that. I've looked through my manual and I know it must've been there in an older version of the BIOS, but not in the latest version.

 

[ko888]

What does CPU-Z report on the Mainboard tab page in the Graphic Interface group box for Link Width and Max. Supported?

Does it also have the same reporting error?

In CPU-z it says pretty much the same thing. Graphic Interface: PCI Express; Link Width: x2; Maximum Width: x16

Do you get a list of ports from Port #02 to Port #07?

Yea that's what it looks like for me and I have the Link Width set to x16. That's really the reason I'm frustrated that every program tells me it's running @x2.

Gb/s is gigabits per second.

16-lane PCI Express 2.0 should have an aggregate throughput of up to 8GB/s. Note gigabytes per second (i.e. 64Gb/s).

 

[MrJets]

Well, I guess pretty much everyone has ran out of ideas by now. I have noticed that in the BIOS, I can set it to x1 and it runs as x1. So it's like I only have the option of x1 or x2, I would love to see it at x16 so if anyone has anything else to add, please do.

 

[ko888]

Clear CMOS.

Run a driver sweeper to remove all remnants of the graphics card driver and reboot.

Download and install the latest graphics card driver.

If that fails try the graphics card in a different system to determine if there is a problem with the graphics card.

Try a different graphics card.

 

[MrJets]

This is what's bothering me. Sorry for coming back now I see you were assisted nicely. But ko888 can check as well look at what aida showed
GPU Clock 157 MHz<--------- that's a bit low ain't it? Power supply maybe?
Op your gpu-z screenshot show 5800 series yet your gpu is the 5770. I suggest you do a clean sweep of the drivers by using a driver sweeper. Then you can either try and update your chipset drivers or reinstall them in windows. I suggest you put them on a disk just incase then uninstall them then reboot. Reinstalling or updating the chipset drivers

Take a look at the gpu-z screenshot again, it says 5700 series. Also, when the card is idle it sits at 157mhz and gets up to 850mhz when in use.

At this point I'm doubtful that anything I do will fix it but I'm gonna use a driver sweeper before clearing CMOS and re-installing the latest drivers.

 

[MrJets]

So I tried clearing the ATI drivers/Clearing CMOS/Re-installing the drivers and that didn't work. Unfortunately I don't have another card or computer to test things in that way, which I know would be helpful.

Correct me if I'm wrong but isn't the chipset installer nothing more than the driver for my onboard gfx?

So no one ever really commented on what I said earlier, when I said:

well the card seems to be working quite fine... And correct me if I'm wrong but isn't a x2 linkwidth a bit odd in every way, usually available linkwidths are x1, x4, x8 and x16.

Mobos chipset drivers should have whole bunch of different drivers, for different controllers and buses (including the onboard gfx, I think...).

 

[Kari]

if you hover your mouse pointer over the bus interface field there should be a tooltip showing some extra info.

 

[Kari]

when the chipset driver gets installed it extracts into 20 to a hundred driver files alot of them with sysextension. The chipset are made out of a lot of devices but the igp aint one of them. theres a different driver package for it. Go to device manager and have a look

even when the integrated chip is actually part of the northbridge?
I dont have igp so I can't.

 

[Kari]

ok so x2 is allowed in the standards
