PC only post with GPU on a PCIe 4x

[brehndo]

The problem: when I put the GPU on the top PCIe 16x my monitor shows "NO SIGNAL". But when on a PCIe 8x/4x it post and run whitout issues.

I've tried in two MBs and the same happens.

 

The system:

• First MB: Gigabyte 970A DS3P
• Current MB: Asus 970 PRO Gaming AURA
• Radeon XFX R7 360 P 2NF5 2Gb
• FX 6300 3.5Ghz
• SSD HyperX Savage 120gb
• DDR3 HyperX Savage 8gb 1600
• PSU Thermaltake 750w Smart 80+ Bronze
• Windows 10 64 bit
• Latest BIOS 

 

Ps.:

• The asus MB have LEDs that shows if have any problems with CPU, GPU, DRAM and boot device. CPU, DRAM and boot device are always fine, but the GPU led turn on when on a PCIe 16x and it's ok on a 8x. Actually, the GPU runs at 4x like it shows on image bellow;
• I've already double checked all the cables and reinserted a couple times the video card;
• I couldn't find anything in the BIOS setup related to this;
• Cleared CMOS;
• I had no beeps whith both MBs;
• All drivers are up to date.

Edit 1: This is NOT my bios, but look exactly the same

Edit 2: I'll send to retailer tomorrow. When I get a response I'll update.

Could the GPU be damaged at all?

Have you tried the GPU in a known working x16 slot ( I know you've tried two different motherboards but maybe the Gods are not on your side)

Any x16 port will work, doesn't matter how old the motherboard is.

 

Have you also tried another GPU in your current motherboards?

 

I'm leaning towards the GPU being faulty in some way.

Tried a different GPU?

[Droidbot]

Does it matter though? Your GPU isn't amazing but it's not like it's gonna saturate a whole 16x bus anyway.

Is this under load? Check again when it's under load.

The entire system is new, but it could be damaged by the Gods... who knows?

I don't have another system to try it;

And no. I'll have to wait 'till next month to buy a new GPU.

Nope. And the only person I know that I can borrow one lives miles away.

Yes, it does! Cause if its a MB problem I won't buy a better GPU.

Click the question mark next to the highlighted box, and run the test. See if it goes to x16.

He can't.
The port is a wired x8, so it can onlt go to x8.
x16 and the PC won't post.

 

You're thinking of power saving features. That would make sense if it was in a x16 slot.

It simply changes from 1.1 to 2.0, but still x4.

Yeah, he made me think about that too, so... I disabled everything related to power saving and still the same

Nvidia and AMD's flagship cards will run fine on an x8 bus without losing performance.

The difference between x16 and x8 it's no big deal. But in my case its running in x4 

[LabRat]

check bios to see if x16 is "live".

Already checked that. I couldn't find anything like this

[LabRat]

what software are you running on both ( like stuff off any of the discs that came with the board?

can you try ( even if you borrow ) another card. if it happens on 2 boards it could be the card............or. wait for it........... the CPU could be bad.

Well, I don't use any stuff of the discs at all, I just downloaded the drivers from the manufacturer's web site. 

I'll have to buy another GPU.

And I don't think the CPU is bad.

Can you take a clear picture of:

1. The PCI-Express X16 slot
2. The PCI-Express metal (gold coloured) pins
3. Picture of your graphics card installed in the PCI-Express X16 slot

There may be a chance that some of the pins on your graphics card may be dirty or damaged.

Just to be sure, I want to have a look at the contact pins ON the motherboard, in the PCI-Express X16 slot.

I don't know if maybe the card is going in crooked (e.g. slightly bent computer case), so that is why I am asking for a picture with the  the R7-360 installed.

 

[SkilledRebuilds]

I had an issue like this just yesterday.

Prior to change I had set Manually in bios that slot1 uses pcie 3.0, not auto.

 

HD7970 didnt display unless in the 2nd slot

Back to bios, pcie is now auto and it works.

Silly things.

I didn't see this option.

This is how my bios looks like

The PCI-Express X16 slot itself, as far as I can see, seems to be okay.

 

I noticed that you do not have any screws in, or locking tabs on the back of the graphics card, but the expansion slots.

Have you always just installed the R7-360 without any screws holding it up, and straight?

If so, that could contribute the the problem -- depending on JUST the PCI-Express slot mechanism to hold the card in place is NOT good.

 

Can you take the graphics card out, and take a picture of the gold pins along the card?

Both sides if you can.

I want to check for any signs of damaged contact pins or two.

 

Examples:

 

 

[LabRat]

easy to see........... the tab that supposed to slip between the motherboard and the case is not in the proper position. looks like it's hitting the back of the case. remove the card and carefully insert the card in then slot while making sure the "long" end of the bracket slips into it's proper position.

I always install my GPUs with screws, unless it forces the motherboard. I took this picture without de screws but it makes no difference with, I checked that.

Here the card's gold pins:

I always test everything before putting inside the case and it happened without hitting anything, so...

[LabRat]

you had your motherboard out of the case when you slipped the gpu in?

AND WHAT'S WITH THE COCKED BRACKET THAT CLEARLY SHOWS THE CARD IS NOT SEATED PROPERLY?

I did a "test bench" with the motherboard box, put the system together and turned on and then a got the problem! And inside the case it remained the same.

 

Yes, in that picture it is hitting the case. I put the card there just to take that photo, when was for testing nothing was wrong, the GPU was seated properly.
 

Anyhow, I'm sending to my retailer tomorrow. They will fix it or give me a new one.
