Using double power input with riser 009s

[Viaggiatore]

Hello, I'm having problems in finding an answer to this question: can I use both of the 6 pin PCI-E connectors plugged at the same time? I'm asking that because I hope to have more voltage stability by doing that.
Thank you all!

That doesn't make much sense but sure why not.

That doesn't make much sense but sure why not.

I'm asking because I have 3 RX 5700 XT which seem very picky with riser version 006c (all of them freeze randomly, so I doubt that they have HW problems). And I also read that 009s 12v led is able to show if 12v line is not good, i.e. like blinking instead of being steady and that connecting both of those 2x6 pin fixed the blinking led issue.
So I was wondering if plugging 2 power sources is "better" for some extent than only one.

Thank you

Freezing? Something is wrong because I'm using two RX5700XT with double fan here and running on riser 006 with no issue at all, have you tried another power supply? I have no problem using 006 risers for all GPUs I have, you can also try mining OS instead

That will not change much maybe you will get worse if you are using double psu and mix up power cables. Gpu draws from riser 50-80w which is 6pin cable ALONE can handle well enough. no need for that. there is bad risers always whatever you connect they can fail, usually buy riser like this 10 risers and 3 risers for back up.

I have zero issue with my 570 & 580, RX 5700 XT seems more power angry on risers, in particular I have a Power Color doing that. Tried many risers plugged directly with a pcie 6 pin cable, same instability. Now going to try with 009s

Thank you, I know what you are saying. But my feeling is that my 5700 don't like 006c at all. Maybe is also a matter of MB I'm using? I don't know

lol  youre doing is nothing will effect the stability, basically other 6 pin pcie is same source as the other one, so nothing happen if you using 2 power

but yeah if doing this make you more comfortable and believe make your gpu gain stability then do it hehe, but dont use pcie power from different psu

It doesn't matter what riser version you have, if it is unstable then you have other failure. Maybe bad riser, bad riser connector and so on. test card per card alone in a 16pcie slot and then in a new riser.

The same card on different 006c risers (working fine with other cards) can run flawlessy for 10 days and out of the blue will restart the miner every 10 minutes or so...I tried everything that's why I think must be something related to 006c. BTW should get a couple of 009s in next few days

Actually it seems IT DOES affect stability

there can be some "sort of" stability if the issue is/or the issue will be a loose/burnt power connector, specially if you are using the sata connection which is the least preferable to use.

it is still better to use one power source because-how will you know if a connection has problem?

if you have a luxury of spare power connection, and you think you want to remove the future possible nuisance of a bad power connection-you can do that.

yeah.."DON'T DO IT WITH DIFFERENT PSU"

You don't want advice, you only want people to agree with your assumptions.
Why bother even asking?

Sorry? I'm asking for advice and giving facts, I just want to understand better and your opinion doesn't help me for sure in accomplishing that. But I see, it's very easy to answer like you did.

[JayDDee]

I tried everything that's why I think must be something related to 006c.

Those aren't facts. You shot down everyone who gave advice with nonsense like that.

If you want objective advice don't bias it with your own opinions.

I have nothing to add to the good advice you've already dismissed.

Did you bother to read all of the comments? As I already said I have RX 580, RX 570 and 3 5700 XT (14 GPUs in total). All cards running on risers 006c. All of the GPUs running fine except the 3 5700 XT which have random glitches. Changed everything: cables, risers (but always 006c), PSUs nothing worked. Do you think this is an opinion or a fact?

There is nothing that even remotely suggests the problem is the model of riser.
That's called jumping to conslusions and makes problem solving more difficult.
Instead of saying you've done "everything" how about listing the things you've tried, in detail,
without bias.

Have you tried the 5700XTs in different slots? x16 slot without riser? different rig?
Probably not because you already bought the new risers with the pretty LED and you just
want confirmation to make you feel better. If so fine, the LED will fix everything.

Yesterday I received my 009s risers and I swapped all of the 006c being used with my 5700 XT cards. First of all they look promising because my most problematic Power Color card is now running steady at 1200 mhz without crashing (I had to under clock at 1100 because with 006c was crashing randomly and very frequently - after 1 hour, 10 minutes, 3 hours, etc etc without a specific pattern).
Overall the RX 5700 XT cards with 009s till now didn't crash or restart at all my rig, I guess time will tell if I was right or wrong but it is looking good.
