Wrestled with one of these for 4 hours today and I have my doubts.  No provision was made for two power supplies, or even 2 power cords fitting into the back grill.  No fans come with, which is okay I guess because I tend to replace them anyways.  The long horizontal fan bracket -- I really wish this were fitted to the front, not so that you had to squeeze it between cables and the motherboard towards the middle of the interior.  The fan bracket is not for 120mm fans, 80mm only, unless you want to do some custom drilling.

You can fit a HP server PSU sideways behind the bottom support bar and a full sized motherboard, so that would be nice -- if I could snake the power cord for that out a pre-punched hole in the grill, but one doesn't exist for that.  So I will have to get my tin snips out and get to work

Don't get this if you have large 3-fan EVGA 1080 Ti cards - they are too tall and their power connectors (2x8) are on the top of the card, so you won't be able to get the lid back on.  Other 1080 Ti's fit fine (Aorus, smaller EVGA 1080 Ti), 1070's are easy to work with in this case.  AMD 480/580's would be a breeze.

I would not get this model if I had to do it over.  It's bare bones and to get it working well is going to require some structural modifications.  Which I would not mind if it were cheaper and if it were not advertised specifically as a miner case.  But brilliant marketing on Rosewill's part, I guess.

I also wish it were all black instead of a black front and bare metal sides and top, but that's a minor point.

It varies from specific model to model, but we generally have found that our GTX 1060 3GB GPUs do best at somewhere in between +75-125 on the Core with Memory at stock and power limit at 80%, at least for mining Equihash based coins. 382.33 drivers

I would recomend to try -500 memory +200 core, power limit 58-59%. I'm getting smth like 280sols and just only 65w power consumption with these settings it's 4.3sol/w, better than my 1080ti which are doing only 3.9sol/w.
I noticed that lowering memory gives more power to the core what is more important in equihash.

What are your 1080 Ti settings that get you 3.9 Sol/W?

You are correct.  1080 Ti's on my 1150, couldn't really do better than 3.0x Sol/w.  I am now getting 3.6+ Sol/w.

And the Ryzen is a decent CPU miner for the power it uses.  Not a huge difference, but enough to matter.

MSI X370 will do 6 Nvidia GPUs, but it is difficult depending on your version of Windows 10 (build version).  My OEM Win10 disks were build 1507 (I think).  Lots of errors, restarts, was driving me nuts.  And that is after I installed the AMD newest chipset drivers.  What's more frustrating, is that Windows Update just crashes and fails over and over with this build version - just doesn't work with Ryzen.

Download Microsoft's "Media Creation Tool," download to ISO and make a USB boot stick (search for "Rufus bootable .ISO"), do not use the Microsoft product, just download the .iso image and use Rufus to make your Windows boot USB device.  This will take a long while to download and run through updates.  Then reinstall Windows10 using the USB stick/key only this time it will be build 1511.  Start the build with one Nvidia card in the main slot.  When you get to build 1511 (and before you install lots of software), make sure the one card is recognized and that you can mine.  You need to then launch DDU and remove all drivers and shut down, not restart.  When shut down, plug in all your other cards.  Reboot.  If Windows doesn't install the drivers, do so manually under Device Driver.

If you errors on startup, hit F11 to get to the Boot order menu and click on wherever you just installed the new version of Windows.

Beware the Microsoft Update Assistant (Blue icon) that comes with build 1511.  Takes forever and it *may* update you to the 16xx build, and if you run it again, it *may* update you to 170x build.  But you'll probably tear your hair out first.

Go to "PC Settings" > System > About: to see what build you have.  If you have build 1507 or lower, that might explain all your problems.  Update to at least 1511.

Disable Hi-Def audio in Bios.  Disable Serial/Parallel I/O.

I think, more than anything else people mention, when it comes to Ryzen and 5/6 GPUs, it is a Windows issue.

I am not so sure.  I put together an X370 rig just to see.  With a Ryzen 7 you can mine Monero + your GPUs can mine away as well.

Two advantages:  using new cards like the 1080 Ti, I see better performance, more like 3.5 Sol/W than 3.x <lower> on an 1150 board using the exact same GPUs.  Nothing changed but the motherboard/CPU.

Also, there is a speed bump up that I notice when using the CPU to mine; that is, the GPU hash rates jumps up a little bit when mining Zcash.

And if you get the 65 watt Ryzen, when the motherboard is just idling (not mining) you'll see right away that the power draw is a bit less.

Biggest drawback to Ryzen is installing Windows 10.  If you get an old OEM disk with Win10 64-bit build 1507, for example, constant errors and freezes.  Ryzen does not become stable until Win10 build 1511 or higher.  But good luck using "Windows Update Manager" to get there.  I would say, get at least to 1511 or build 16xx, and then  stop there and mine.

Yes.  Unless it's a hybrid pos. But on any large, 3 fan 1080 Ti, yes.

i found this one on system log...

Use Display Driver Unistaller to completely remove any AMD drivers, then reboot.  Repeat the process to remove any Nvidia drivers, reboot.

Then re-install Nvidia drivers.  It will probably recognize all your cards if you try that.

Give it a shot, it will only take 5 - 10 minutes.

Yes, I had the same issue.  Use Display Driver Uninstaller to remove all traces of the Nvidia drivers.  Shutdown.  With all 6 cards connected to the motherboard, restart.  Reinstall Nvidia drivers, wait a long while as it works through all 6 cards.  That solved the problem for me and it was driving me nuts.

Hi Sir! Can you please help me. Why does my bios doesnt have setting enable 4g? Even i updated to the latest version as of now. Please. Thank you!
[/quote]

You need to change from EZ Bios settings to > Advanced BIOS.

Then choose the <BOOT> menu.  There you will find the 'ENABLE 4G' option.

Enable 4G is *not* under the <ADVANCED> OR <TOOLS> OR <MAIN> menus.

It is under <BOOT>.

Turn enable 4G on, disable unused SATA/USB ports.  Set speed for PCIe to Gen1.

Then 7 cards will work fine.

If I understand what you are saying, then I disagree.  I have multiple rigs, all have 2 PSUs.  One PSU powers both motherboard power connections (24 pin and 6/8 pin), the SSD, and will typically provide power to one or two GPUs (both the 8-pin power connection AND the Molex/Sata adapter connection to the bottom of the riser card).  The other PSU supplies power to the other 4/5 GPUs, both at the 8-pin power connection AND to the card's Molex/Sata adapter.

No issues whatsoever.  Just luck on my part?  Did you ever personally experience any issues by connecting the 2nd PSU to the riser boards (not just the 8-pin GPU power connection)?

I got better results with SGMiner 5.5.5 than with Gateless Gate.  Intensity setting of 128 works well, intensity setting of 256 is too intense and leads to crashes.  Algorithm "talkcoin-mod" "nist5" same thing, same hashing speeds.  Set a high fixed fan speed.

My SGMiner .CONF file looks like this:

{
    "pools": [{
        "name": "Solaris",
        "url": "stratum+tcp://pool.solariscoin.com:3032",
        "user": "LoginName.WorkerName",
        "pass": "WorkerPassword",
        "profile": "solaris"
   }],
    "profiles": [{
            "name": "solaris",
            "algorithm": "talkcoin-mod",
            "Intensity": "20",
            "worksize": "128",
            "gpu-threads": "1",
       "gpu-powertune": "20"
    }],
    "default-profile": "solaris",
    "no-extranonce": true,
    "no-submit-stale": true,
    "temp-target": "75",
    "auto-gpu": true,
    "gpu-fan": "55",
    "temp-cutoff": "85",
    "temp-overheat": "90"
}


Try that and compare to GatelessGate.

Z97a Gaming 7 is even better and I don't get those weird “shell” messages on your screen, with a “startup.nsh” when you move components around.  BTW if you get this screen "startup.nsh" using MSI Gaming 5 just move the SATA connector from your hard drive to a different SATA port on your motherboard.  With one or two moves, "startup.nsh" goes away and Windows boots normally.  No need to reinstall Windows if you see this.  I have not seen this error message with the Gaming 7, which has more USB 3 ports, HDMI, power on/reset buttons right on the mother board (no need for a paperclip, no need to power on cable).

Gaming 5 is fine, but I love my Gaming 7.

6 RX480s works very well under Windows 8.1, 5 RX480s should be no problem under Windows 7.  Try AMD releases 16.10.3, 16.11.5 or 16.12.2 but I have fan issues (random speed ups) with 16.12.2.  Use DSEO or amdpatcher.exe to sign the drivers, turn Testsiging ON using BCDEDIT commands.  Of course download Net Framework 3.5 beforehand (not 4.5/4.6/whatever) to get 6xGPU to do it's magic.  Install one card at a time, copy signed drivers over into C:/Windows/System32/drivers each time you add a new card, run 6xGPU each time you add a new card.  If you make a backup of your "signed" drivers and simply copy them over to Windows/Sytem32/drivers/ then run 6xGPU, and the reboot, should work fine.  Works fine for me.  PM me if you want all the details, but should be rock solid.   No more dreaded "THREAD_STUCK_IN_DEVICE_DRIVER" :-( if you follow these steps.

Can't say about RX470s, but not a problem for RX480s.

3M 90 adhesive will stick those black pads back on.  Home Depot carries it.

Okay, that works!  Thank you very much.

What's wrong with the pool?  Hash values all over the place...

Yes, Cryptopia is fine.

different problem:  website is not allowing password resets - yes, in my excitement I forgot

That's great advice.  You'll also avoid the hassle of getting 6 cards recognized properly in Windows 7/8/8.1 if the rig is running Windows.

Search for David Mercer's Zcash - he has a good gui Windows wallet and and OSX wallet as well (I think).  Windows wallet works pretty well except that you have to be careful to deduct a bit more than the suggested fee before sending to a hardware wallet or somewhere else.  He will eventually add a "maximum" button like in Jaxx that auto-subtracts out an applicable fees.
