Mining Rig - Airframe Upgrade

My make shift case from Bed, Bath & Beyond bent on me due to me putting some weight on top of it.  Good thing is that no hardware was damaged but the rack is now unusable.  Instead of buying one from eBay that go anywhere from $85 to $300 (most you must assemble yourself) I decided to make one.  Lucky for me I have a family member with tools and he precut all the aluminum and wood for me.

The YouTube video I followed is here.

Here is what I ended up with:

Fix for Claymore Miner Randomly Restarting

So, I have noticed that my claymore miner will freeze and then initiate a restart of the miner.  While I think that is a cool feature in case of a lock it was happening frequently enought that it started lowering my hashrate averages.  I did some research and tried MANY different things (most made things worse) until I found out what I think is the issue.

My issue was two fold.  Not enought COUNTINOUS page file space and PCI-E power savings under Windows 10.

Note:  Stop all mining and reboot before appling these fixes.

The Build - Overclocking

Overclocking is difficult

I have found out that not all GTX 1070 are the same.  There is a HUGE difference between manufacturers and different versions.


I ended up getting my 6-GPU rig overclocked to an average of 179MH/s (which is ~29.5MH/s per card).   
I am sure there is more tweaking to do as I move foreward, but I am going to leave these setting for a week or so before going back and adjusting.
Through research the GTX 1070 should get an average of 30MH/s per card in a stable configuration.


The Build - OS and Software Install

I was actually very surprised that this worked without any issues.  From Windows install and updates to actually mining was just under 3 hours, which isn't that bad!  I am running the rig in a stock configuration without any overclocking to make sure there aren't any issues.  The rig is doing ~150Mh/s for ETH with its current configuration using Claymore Dual Miner 9.6.  Claymore 9.7 only ran for a few mins before crashing but 9.6 seems stable.

After this burn-in period I will start to overclock with the hope of ~180MH/s.


What I did:

Making an ETH miner - The Breakdown

With ETH (ethereum) hitting going over the $300 mark, I have decided to try to build an ETH GPU miner.  Researching what it takes to build a miner seems to be pretty simple.  You need GPU's, motherboad, processor, memory, a hard drive and a case.  Sounds pretty simple and worst comes to worst I have a bunch of very sellable or re-usable computer parts.


My HOPE is that ETH will have a growth rate like bitcoin.  Bitcoin is currently ~$2567 and was trading ~$400 around a 1.5 years ago.
