My r7 370 is not working with 2 pci-e extensions

[Candor]

I'm pretty sure that 20% power limit is default and correct.

I hate to say it but I think we have exhausted all the options I can think of.

For some reason the signal for detection of the card just isn't happening.

The fact that HD5770 works means the 370 may be on the way out.

It seems to be a case of signal strength or timing. It could be that the card has deteriorated or has a component that isn't performing as well as it should.

You may find that new pci-e extenders may work or may not. That's a cost to you and that may be a futile endeavour.

Either way, I think we have been beaten today.

i will keep trying I want to remove the fans from video card , to see if something happen

 

[Candor]

I also just had a thought.....just check that the pci-e connection pins on the card are nice and shiny-clean.

 

[vrl112]

I removed the fans , the same result , is not detected , now , i removed one extension , is running fine , with ONLY ONE extension .. wtf

 

[Candor]

Because of "reasons". It's just a quirk with that particular card it seems.

IT JUST DOESN'T WANT TO

I understand your frustration. Any other gpu's lying around to try?

Otherwise, sell it and try another one.

I saw something, when the gpu is not detected ,after i turn on the pc the keyboard is turning on , the lights are on, after 2 seconds, the lights are off, the mouse is on, is there a conflict?, or something like that ? Because not every time is doing like that.
I have another card , but very old , i will try with that , i hope you understand the issue with the keyboard

 

[Candor]

Yes. My keyboard lights do the same thing. It's definitely not a conflict.

 

[vrl112]

These are the results for unigine valley benchmark, i saw on youtube the same test and he got score 1810, the gpu is with one extension connected

Does flipping one cable over make a difference?

 

[Candor]

If you mean swapping the order, we tried with no change.

Yeah there's no question the card works. It just doesn't want to play with your 2 pci-e extensions.

I'm curious what is your motherboard bios version?

I only ask because:

Version: 7A34vAC
Release Date: 2018-03-12

Description
- Improved memory compatibility.
- Improved PCIE device compatibility. ******
- Update AGESA Code 1.0.0.1a to support new upcoming processors.

No, I meant physically flipping one cable over 180 degrees.

 

[Candor]

I don't think you can....can you? Because of the notch?

 

[vrl112]

The power cable ? or the extension ? My Bios version is E7A34AMS.AE0 fronm 05/02/2018

 

[Caring1]

I don't think you can....can you? Because of the notch?

Yep, just checked mine, and it is notched.

 

[Candor]

Couldn't hurt to update your motherboard bios.

May as well try anything at this point.

 

[vrl112]

the power cable doesn't have any notch, right now I'm updateing the bios with the latest version

 

[Candor]

...and the computer never booted again...

 

[vrl112]

no , the bios is the last version now , i checked the extension with another pcie card , but very old , without power cable , and is not working at all , even with only one extesion , is not working

 

[Candor]

Well, I am out of ideas unfortunately. Sell it and get another gpu.
