Need help to build mining Rig with 5 X R9 380's
Hello,
I need some advice on what hardware configuration I need to build a mining rig with 5 x R9 380's?
What Processor, HDD, MoBo, PSU and what accessories I need to can connect 5 GPU's to MoBo? And ofcourse anything else I may need?
Any advice will be appreciated.
Thank You

Hello, I looked in the forum and generally I understand what I need, but just wanted to know if there is anyone using the same GPU and can share his rig configuration
I figured out this config:
Intel Celeron G1820, BX80646G1820, 2.7GHz, 2MB, socket 1150
Asrock B85 Anniversary, socket 1150, 4xDDR3, 4xSATA3, ATX
5 x ASUS AMD Radeon R9 380, STRIX-R9380-DC2-2GD5-GAMING, 2GB GDDR5, 256bit
PSU Zalman GVM Series ZM1000-GVM, 80+ Bronze 1000W
Kingston HyperX HX316C10F/4, 4GB DDR3, 1600MHz, CL10
1 x PCIe 16x Riser Card
4 x PCIe 1x to 16x Riser Card ( here I don't know what is better USB risers or Flex Cable? ) Please Advice
SSD 30 GB
Total Cost =1400$
I buy everything from Romania ( I'm from Romania ) and we have bigger price's on hardware.
Also I have another question. I already have my PC, which I use every day. I have a good MoBo with 5 PCI x 1 slots. But I have GTX 960 as graphic card. Do you think it is possible to install another 4 or 5 AMD GPU ( R9 380) and to configure it, that for mining to use only AMD GPU's and GTX 960 to be used as display card? So computer would work as usual, with no delays? Would it be difficult to configure, taking in account that onbord will be Nvidia and AMD?
Thank You very much for help
Yes, you can configure your PC that way, but your are going to need a big psu. Don't go with cheap psu's; they are not going to hold up under the 24x7 full-load that mining requires.
About PSU - what is minimum that I need for 5 GPU's?
I though Zalman is a good brand for a PSU, also it is certified. I understand that a good PSU is very important, so I want to buy something very good.
Is there on the forum threads how to configure rig with different gpu brand and how to use one card as display and others for mining?
You can also take a look to the LEPA G1600 : it should be less pricey than most other the other quality PSU while still being a good one (check http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html ).
I bought everything, MoBo have 3 PCI Express X16, X8, x4 + 3 PCI E x1. I connected 3 GPU to PCI Express and all are visible and mining corectlly. But when I add another GPU with Ribbon powered Riser form x1 to x16, it is not visible by computer. Cooler of GPU start spinning, but in device manager it does not appear. The first 3 cards are visible and work fine. I tried 3 different risers, with two of them computer start, but the card is not visible. With third riser, MoBo start beeping for a few seconds and turnoff, even don't load bios. Where is the problem? Is there anything to do more, to make it work?
I use ribbon risers because I don't have other options at the moment
Thank you
2. Try to disable audio codec in BIOS - it also occupies one PCI-E lane.
The R9-380 might not work with a VGA/analog Display. I know the R9-390's don't. They need a DVI-D Digital one. Check to see if that's an issue.
Try with 1 card in there first. Disable the built-in display in BIOS and see how it goes with no other cards connected or even plugged into the Power supply.
One often has to use only certain specific slots when running a +4 card config
For example, on my Z77A-G45 (3x full length, four 1x) some of the 1x slots share a lane and can't be active at once. (I'm able to put a card in either slot 3 or slot 4, but not both)
There's also an issue with the X8 and X4 slots and x16 risers or directly mounted cards, if the board tries to run them at x8/x4 it may disable other PCI-E x1 slots to do so.
Depending on the motherboard, there may be BIOS options to choose what the x8/x4 slots run at... or you might need to populate them in a certain order.
There are also boards with slots that require a PCI-E presence short when using 1x risers (USB risers do this by default)
After that, check all the risers one by one with single card. Maybe some risers are broken.
I tried all card's to be sure that they are working. And they do.
I checked all the riser with the same card, but how I said 2 of them let the computer to start, but card is not detected by the system and and with one of the risers when I press start button, MoBo just start beeping and turnoff the system without even loading the BIOS.
One of the 3 cards is connected to PCI-E x4 with an extender bought from the same store as risers and it works fine. Only PCI-E x1 slots seem's not to work
I saw on internet something about a jumper on PCI-E x1 slot. May be this the case?
In the BIOS I don't any option to disable or enable any PCI-E

I can assume that when you connect any device to long PCI-E slot at the bottom of your mo-bo, you disable all short PCI-E x1 slots.
So try not to use PCI-E slot at the bottom of your mo-bo.
I have 5 GPU's, but can run only 3. I will see, may be tomorrow I will can find somewhere USB risers, to try with them, may be there is not enough power in this flexible cables to transmit data.
Thank you all for help
Try the other ones one by one. If they also show the same, chances are it's a driver issue.
If they don't it's a bad card.
I guess it's still possible your motherboard is bad too, but eliminate the cards and driver issue first.
Now I tried to connect one of the card to another computer, with another MoBo via PCI-E x1 and the same riser, and windows detected the card! Even if on the MoBo already was another Nvidia GPU! So now I suspect that problems is because of the MoBo. I have to see what I can do ....
2. install latest intel chipset driver.
3. Install crimson 16.2 driver.
Any suggestion?
Thank you for help!
After I will manage to make actual MoBo to work ( If I will... ), I want to build one more rig, but now for sure with different MoBo. Do you think it is ok? And it will be more easier to install cards on it?
Thank you
On the 380, you should be able to get down to a bunch under that.
Does ASUS Tweak work with other cards?
1.reset motherboard BIOS
2. connect first card to first pcie x16 directly and connect vga cable to it, it should be ok
3. if 2 was ok then remove card and now connect it to first pcie x16 using riser, check do you have screen?
4. if 3 was ok connect another card via riser to another pcie x16, if it detected continue to add other cards one by one in pcie x1 slot
