The maximum PCI-E specification of a PCI-E 8-pin connector is 150W, not 360W. The maximum specification for a 6-pin PCI-E connector is 75W.




The PCI-E specification is not just based on wire gauge. It's also based on power delivery. Wires and connectors have resistance. The voltage drop and power dissipation as heat increase as you increase the current. The resistance of connectors also tends to increase as they are plugged and unplugged so after enough uses they can overheat and even melt when passing a large current. Which is why it's NOT safe to overload a 8-pin connector with more than the rated specification. ESPECIALLY for a mining rig under constant high load 24/7.

Except that it's not. For one thing the total capacity of the PSU has nothing to do with the maximum rating of the individual ports or the cables. RX 570's even undervolted, mining Equihash or dual mining can easily use 100-110W each from the VGA 8-pin. In the best case, that's 200W+ from one cable. Depending on the gauge of the wire used for the cable you would be far exceeding the the rated capacity of 18 AWG cable, which is 10A or 120W max at 12V. If 16 AWG cables are used, you would still be drawing over 200W from one PSU connector and it's NOT safe, especially for use in a mining rig under constant load 24/7.

Splitting an 8-pin PCI-E connector to dual 8-pins is not recommended. That's a good way to overload the PSU cable and rail with up to 300W. That PSU has 4 PCI-E ports. With 3 cards and 6-pin risers, you can use 3 PCI-E ports for the VGA 8-pins and use a 8-pin to dual 6-pin splitter cable to power two of the the 6-pin risers. The last riser can be powered with a 4-pin molex to 6-pin adapter cable.

If you're running v1703 it should be compatible with the v1709 fall update. I would try the Microsoft media creation tool to create a bootable flash drive with the latest build and do a clean install.

I wouldn't suggest overclocking and undervolting the cards through the Bios for just a couple rigs. If you're using Afterburner with the AMD blockchain drivers for up to 8 cards, you can unlock voltage control in the Afterburner settings. A better option would be to use the Claymore config file to automatically apply the settings at runtime or use OverNdrive tool to create overclocking profiles for your cards as explained on www.mining.help.

There is no 'as it should be' overclock setting. How much you can overclock the memory and undervolt a card depends on the Bios mod and ASIC quality of that particular card. Assuming you did a good Bios mod based on the cards memory type, you need to find out the best settings to use for each card individually. The way to do that is to try different settings and adjust them based on the results. A good guide to use is www.mining.help.

Yes, unfortunately you bought CPU/RAM that aren't compatible with each other. I would exchange the RAM for a 2133 MHz DDR4 that's listed on the QVL.

Your Celeron CPU only supports 2133 MHz DDR4 RAM.

Typically the faster memory speeds are only supported by the higher end processors, like the i3-i7. Either return the RAM or CPU. It's always best to go off of the motherboards qualified vendor parts list to make sure you are using a CPU and RAM tested to be compatible with the motherboard.

You bought 2400 MHz RAM. According to the specifications 2400 MHz RAM is only supported with KabyLake CPU's. What processor do you have?

Yes, leave all the PCI-E slots empty, connect the monitor to the DVI port and see if there is a video signal during POST. If you can get to the Bios. What is the model number or link to the RAM you bought.

Disconnect the GPU's from the motherboard and see if the onboard video is working. What RAM are you using?

Check for memory errors with HWinfo, it could be a bad Bios mod. -20% power limit is very low for RX 580's and too little power will cause them to crash. I set mine to -15% or to -5% on the ones that crash. Dual mining GPU power only is around 100-110 W in GPU-Z.

Try using OverNdrive tool to set the clocks and power limit, like it says in www.mining.help instead of using Afterburner. I set mine using the Claymore config file that automatically applies them when the miner starts. It could also be a buggy miner.

30 minutes?   Try 30 seconds if you're lucky. Basically unless you are at the computer to click on the email link the moment you get it, login and go through chceckout, chances are you will be too late. I keep nowinstock.net open to monitor all the different websites and set off the alerts. It's usually faster than waiting for the email.

The motherboard should automatically switch to the GPU video output once a card is plugged in the primary x16 PCI-E slot. With new GPU's, it's usually best to use the latest drivers from Nvidia. Before installing the latest driver, you should use DDU in safe mode to uninstall the driver Windows automatically installs. The first time you run DDU it will automatically disable the Windows automatic driver install, then select clean and shutdown to remove the drivers. After shutdown connect all the x1 GPU risers to the motherboard and install the latest driver. I also enable the group policy to disable driver updates since I don't want Windows Update to change the drivers I install.

gpedit ==> Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

Many RX 570/580 have dual sets of timing straps. PBE shows the memory type for the first set of timings in the drop down by default.

I use the latest AMD Adrenaline v17.7.2 drivers on Windows 10 v1709. You need to toggle the GPU's to compute mode in AMD settings. I also enable the group policy to disable driver updates in Windows Update.

You need to use Claymore v10.3 with the AMD Adrenaline drivers. Dual mining I get about 29.8 MH/s 895 MH/s DCR with ~105 W VGA power only with a modified Polaris Bios Editor v1.62 'one click timing patch' strap. The only change I made was to copy the PBE bundled strap to the 1625 and 1500 MHz straps on the second set of timings as well. The overclock settings I use in Claymore are:

Since they are mining cards, you can probably run all of on the Asus B250 mining expert motherboard.

To be fair, the problem with the lack of profitability from the D3 was compounded by the DASH block reward structure, which reduces the block reward as the difficulty grows. The massive influx of new D3's on the network created a double-whammy where the difficulty rose exponentially, while at the same time the block reward was being reduced the more the difficulty grew = a race to the bottom as more and more hash power hit the network with each successive batch. In the DASH block reward structure, 10% of the DASH block reward goes to the treasury system and the rest is dived equally between miners and masternodes, further compounding the problem for miners.
 
LTC and BTC are much more capable at handling a sudden influx of hash power due to the block reward and transaction fees going 100% to the miners and their difficulty adjustment structure.

2175 MHz memory overclock is very high for a Bios modded RX 570 4GB card, which have slower memory than 8GB cards. My Sapphire Nitro+ RX 570 4GB card has Hynix memory and I can only overclock it to 2020 MHz before it starts producing tons of memory errors. It also depends on how aggressive the Bios mod timings are.
