Hi everyone,

Me and couple of my friends are thinking about buying a huge amount of GPU's for mining. Yeah i know it might not be profitable soon blah blah blah, thats not the problem, the problem is that it is extremely difficult to find a supplier that could offer 1000 piecesof RX 580 Graphic cards. I did buy 240 pieces in the end of the last summer, and I managed to find it in the local stores. Now it is impossible.
The question is if any of you guys know how we could order this number of GPUs?

Thanks for the replies, I will try another mobo today, to see if its the problem of PCI-e 2.0

@Cereberus
Yes, I did try Windows 10 as I mentioned before, but I got a lot of bluescreens, even when installing recommended drivers for Vega56, I did not get these errors on Windows 7 until I tried to install blockchain drivers.

Thanks, I will try using Simplemining OS today.
Any other suggestions what might be wrong ?

Hello,
I am building my first GPU mining rig (GPU - (6x) Sapphire RX Vega56; Motherboard - H81 Pro BTC 2.0; PSU - (2x) EVGA 850W; SSD - Corsair force 3 60GB; RAM - Kingston 4GB 1866MHz DDR3 CL10 DIMM HyperX Fury Red Series) and there are a couple of issues regarding GPU drivers:
1) When Official recommended drivers (from AMD Radeon Official Driver Utility) are installed on Windows10 there are a lot of BSOD (Kernel-power 41 and other) while trying to install other drivers or opening AMD Radeon Control Panel. We didn't try to install Blockchain drivers on Windows 10, but I have a feeling that BSOD's wouldn't go away.
2) While using Windows 7 and the newest official drivers - everything works fine. However, after uninstalling these drivers with DDU and installing blockchain drivers (also tried installing them on top of recommended drivers) - PC instantly reboots and shows an unexpected shut down table (BSOD error) when HDMI is inserted to GPU from Motherboard (while PC running). And if the rig is being turned on with HDMI inserted to GPU then it keeps rebooting without showing anything on the monitor.
Some details: - There is only 1 GPU connected to the motherboard and it's inserted into main slot; - Motherboard has PCI-E 2.0 while PCI-E 3.0 is required. However, I've read articles that people are running rigs with identical components to mine (read above).
In Overall, the rig is able to mine, but it would be great to get some help regarding these issues.
P.S. Yes I've tried different GPU's and different risers, as well as PCI-E 16slot.
P.P.S. There are many people using PCI-E 3.0 card in a PCI-E 2.0 slot, because as far as I know they are backward compatible, is that right?

Maybe simplemining OS could help?

Hi guys,
I am a new to crypto-currency mining, but I am still willing to start mining in a month. I am planning to invest 50-100K EUR in mining 25-50 GPU mining rigs(6-7 x RX480 i guess) rigs, for Ehtereum/zCash/Monero etc.
I know about difficulty bombs, as well as Casper coming out in late 2018 (hopefully), but according to my calculations I will still get my investment back in about 12-18 months (I guess I can still sell GPU's after (if mining wont be profitable anymore. I know it is a risky investment, but I guess everything in this market is. But everywhere I go I see people complaining about market beeing overflooded, not profitable mining, and mostly a lot of negative oppininions about starting mining right now. Am I missig something, does anyone have a constructive oppinion why would GPU mining be unprofitable soon for sure? Any advices for a noob like me? What rig components would you suggest? Any oppinions about Nicehash (I only found out about it yesterday, so I dont know a lot about it). Any info is more then welcome. Thanks in advance.
