Which card is which?

[pornluver]

If we go to gpu-z or atiwinflash or watttool, we got cards sorted out. There is this first, second, bla bla.

I wonder which card is which? Anyone knows? Do we know that the card in PCI-e 1 is always the first card and so on?

i change the fan speed to max for each card one by one to know which card i am controlling then change it back to auto

Gpu-z and atiwinflash should use the same order.
As for watttool it's a bit imprevisible. Anabil's solution should work fine to find the order out though :p

That's exactly the problem. Anabil solution works only if card is running. If card is not running then all fans are off. When card is running, all fan is close to 100%. I suppose I can turn off some card in claymore. But all fan keeps going.

Perhaps the LED would work but that means using sapphire trixx. Is the order the same with watttool?

[Ambros]

I cannot provide an answer, I use the same 100% trick..

I want to extend the question, someone has info about Claymore ordering?

I am not saying you're wrong. But the trick need more detail. For example, we need to run something "light" so all cards are working. Then we got to adjust fan speed.

In claymore ethereum you can turn off cards by pressing 1, 2, 3, 4, 5, 6 I think. But last time I did that, all fans are on.

i think there isn't a easy way to tell, it's not always the first gpu in the first slot, but you can be sure that the hottest card is the one near the cpu with the pcie x16, try nvidia smi command tool to tell in what position the gpu are

[cashen]

I made a cheat sheet.

Slot
Claymore
WattTool

I did it once and it has stayed the same

It seems that the first card is always the one connected to the PCI-e 16x. At least according to Sapphire Trixx.

Then the second card is following the order

So if the position of your PCI-e is 123456

I use btc pro.

The first card is 2

Then the second card is 1

The 3rd, 4th, 5th, and 6th card is as pci-e number

Turn off the cards 1 at a time in claymore. Whatever monitoring tool you use, check which card goes way down in power consumption/usage. Your fan can stay high, but those numbers WILL go down when you turn the card off in claymore.

Ah a good idea.

So the sequence in claymore will differ from the sequence in watttool?

What about sequence in watttool vs sequence in gpu-z?

[miner417]

Claymore's sequence is finicky, it doesn't always show the order correctly. For GPU-z and Watttool, they should both show the same order, and NORMALLY, it's the order that they're plugged into the mobo, but again, I'd suggest just using what I said to make sure.

These are the order for 2 of my rigs

GPU-z   Wattool   Watttool Index   PCI-e   Claymore   power   voltage   mem voltage
1      0      0      1   75   910      900
4      1      2      3      910      900
2      2      4      5      910      900
3      3      6      2      910      900
0      4      8      4      910      900
5      5      24      0      910      900


How do I find out?

I change frequency in watttool from say 2125 to 2126. Then I look around at GPU-z to see which changes. Then I jot that down. Then I turn off some card in claymore.

Finally, I turn off some card in claymore and go look at the machine. After a WHILE, the card that is off will have the fan stop working.

The order is always the same for both of my rigs.

The only things that changes is the watttool indexes. It's
0
2
4
6
8
24

In others it's
0
20
8
14
2
36

Also the 5th card in wattool is always the card that is on PCI-e 16x. It has samsung memory that should have 30.5 mh/s. However, it only clocks 28.5 mh/s

I have no idea how. If I get rid the 4 hynix card, the one with samsung will give 30.5 mh/s for ethash as expected. Put 4 hynix memory and that card performance drop
