help with My rig

[GryphoCry]

Hello,

Im newbie on mining, i've Just finish building my first rig with 4 sapphire rx 580 8gb, but Im having one problem, windows recognized my 4 GPU's but fans arent working, i tried using MSI Afterburn but the software cant even recognize any data such temperature. Im using 1000w psu idk thats the reason...

If i only connect 3 GPU's, they work fine, i Just need to have msi Afterburn on background to keep fans working.


Im using biostar tb250-btc pro, Intel pentium g4400, 4 gb ram.
What can i do?
Sorry for My bad english xD and thanks in advance.

what cpu do you have? is it a skylake or kabylake?
how about psu wattage? theres lots of information you didn't mention that would be very helpful

[Wusolini]

I would say PSU is the reason indeed.

Count with me.
80% PSU efficiency, gives you real 800W
70W for CPU, 5W HDD, some 10W RAM and MB ...do you have any other SATA devices?  gives you remaining 700W for 4 GPUs .. I don't think that's enough.

Thanks for the help, cpu is skylake, and the Psu is 1000w
EVGA SuperNOVA 1000G2

Thank you, if thats the problem, would you recomend installing another 1000w?  or maybe more? ... Considering that Im planning to install another 2 or 4 rx 580.

no its not power, he is using the tb250-btc pro, id say bios settings
go into the bios and look for pci express settings, possibily some pull down menus, change gen3, assuming that's the default to gen 1
also enable 4g decoding

[Wusolini]

I bet CryptoWatcher420 has much more experience with, so do as he says.
The above was just my assumption.

But for 6 GPU rig I'm almost positive you going to need a stronger PSU.

I dont think so, still it depends on how much undervolt can you go.
I personaly use RM1000x for 7 rx 580 8GB with 1150/2100, and it only cost me 850w max.

its not all power, there are other things that come into play depending on the motherboard used, me personally I use a 1200w server grade psu for 6x gpu with stock settings

he isn't at 6 yet, he is at 4. but you are correct to give proper head room 1200w is good for most setups
1000w is okay depending on how much actual wattage those gpus use

The hardware configuration setup seems fine, nothing should be wrong with that. Try:

- changing the slots of graphics cards.
- complete uninstalling of all the driver-related software and install an older version of driver.

changing slots wont do any good on that motherboard, he has to change the bios settings
no 4g decoding and leaving the pci express on gen 3 the mobo wont pick up anymore than 3 gpus that will function with mining

[maralet2020]

go for nvidia for 6 gpu on that kind of psu. or else. buy a bigger capacity psu and spend time on oc and undervolting amd's

[PotatoM12]

What worked for me was enabling 4g decoding in the bios.
I do have nvidia instead of amd.

Thanks everyone for you comments and help, i will try with the bios when i came back to home, and i think is worth to mention that when i power up the pc all gpu fans and leds work until Windows 10 start.

Im using the latest amd drivers, Im also going to try installing the drivers that came on a CD with GPU's.

And again thanks for all the help, i searched trough Internet and YouTube but i was getting a bit desperate.

[fanatic26]

all gpu fans and leds work until Windows 10 start.

I have GPUs that dont run the fan unless the cards are under load.

Also, you need to get rid of Windows. It is the number 1 cause of mining issues. Read through the posts of people asking for help with their rigs, its 90% windows users that have problems.

Im having the same issue with only 3 vega 64s working on the asus maximus iv extreme p67 i have a 1500w and 1010x hx power suply. The bios doesnt have an opion  to change pcie settings to gen 1 or 4g decoding (unless my eyes are painted on) so im very fustraited that 3 out of my 4 cards dont work.

all gpus do that with windows bud, amd or NVidia. and to the fool whom said get rid of windows. don't listen to that guy there is lots he isn't telling you about Linux, like the fact its NOT newbie friendly. then you've got those Linux mining os's that aside from ethos are just crap especially the ones that want a monthly fee for a part of there service. Linux is great if you already are familiar with the OS otherwise its just a pain in the ass

did you bother to update the bios? a lot of the time the first version of said mobo bios doesn't always have all options and a lot of the time get put in later

Hi yes mate i have the last bios update ever released (3604)

I did everything you said, thanks for the help,

Now my GPUs can mine on Claymore, but the fans  are running a bit slow and whenever they want xD (GPU0 t=76C fan=32%, GPU1 t=76C fan=29%, GPU2 t=76C fan=27%, GPU3 t=76C fan=28%) and i cant control them with MSI Afterburn, any suggestions to that?
I think im going to install previous drivers. Or even the AMD  Radeon Software Crimson ReLive Edition Beta for Blockchain, what would you suggest?...

Also the mining rate is very slow, im using nanopool ETH only and im getting 67.22 Mh/s (16.80 for each GPU) but i know i have to flash them, im already reading how to. Worth to mention they´re Hynix.

Thanks in advance.
