Do my GPU work, or not?

[Seizan]

Yo!

One fast question: No matter what settings are set in windows or bios, the power light will be lit on the gpu if its working?

 

-Having issues with second gpu in second PCIe slot, its not detected and no power light is lit.

 

-Since i just finished a custom water loop on those two cards, I really dont want to take em out to look for errors if I dont need...

GPUs dont normally have a power light? do you mean fancy lights such as making the logo glow e.t.c? then yes it should be on while the PC is on

Iirc, there are leds on that gfx card that indicate GPU load but there are no simple power indicators.

I assume you tested the gfx cards before watering them?

[Seizan]

Yeah there is led lamps that indicate GPU load, if no load it has always been one lamp that is lit. Didnt test them right before watering them, but the waterblocks was on from an earlyer build. Took them out from that build a few days ago...

[APasz]

Sounds like the load indicator doubles as power indicator. So both were confirmed working, right.

Either the card is dead for some reason. Probably static.

There is a missing connection somewhere.

Or there is a compatibility issue.

 

Try (if possible) to have just the second problem card installed and powered. If the system boots, we can assume there is some type of compatibility issue.

When i try with the power cables disconected from GPU one ad have the monitor cable on power cable conected to GPU2 (the trouble one), when i start the pc then the monitor detects a signal and turns on, but after a couple of seconds it goes back to sleep mode...

[APasz]

You need to take the first card out of the PCIe slot as it gets power through it.

[Seizan]

You'r prob right, but then i need to empty the water loop and modify it to one card, will be A LOT of work. Will try to see if I can find out something else before I do that ;;

 

[APasz]

Why'd you need to do that? Do you have one of those weird rigid dual card blocks?

Lay the PC on it's side if possible and just set the card down next to the slot (preferable with a bit of paper in between the pins and mobo).

[Seizan]

No dual card blocks, just made a tube from top card to the next one. The water loop is very custom made, as shown in the pic lol. there is also show what i mean lamp lit on gpu 1 but not on 2.

[APasz]

I don't see what the issue is.

The PCB has flex, just enough to allow the card to sit next to the slot.

It's a tedious maneuver with both cards watered but it can be done. I've done it on more than one occasion with client PC's.

[Seizan]

Yep, but will do that tomorrow. 1AM here now, so best to taking a break before i continiue working on that pc;)

 

TY for help and advice so far tho!

-- Big picture snipped out -- 

 

Check the PCI-E power connections on the top card.

I can't see it very well in your picture, but it looks like one of the PCI-E connectors is not in properly.

 

Also, when running the GPUs in Crossfire, you're suppose to connect your monitors to the PRIMARY GPU (e.g. the top one).

The second GPU functions as a "slave", and the output ports are disabled.

Got second card tested in first PCIe slot, and it works. So that makes it an MB issue or some software thing.

 

Thing is now i might have fuked things up, when i going to put the cards back i acidently pulled them a part, and result was ofc cooling liquid flowing out! 

Atleast i had pulled out power cord from PSU before i started this, but.... guess i'll see how stuff are after i get it dryed up lol

 

Dont do this at home >>

So it was all tested prior to the build?

Yeah, kinda

[Seizan]

Okay PC dryed up and nothing seems to have taken damage

 

So now back to the issue, the pic show the bios that only one gpu is detected while there is two...

[Mick Naughty]

Test the good card in the other slot. 

[Seizan]

Both cards are good

[Seizan]

But well, i should maybe make a new thread since i now know the GPU isnt faulty.
