Supposedly so, definitely hope so.

I a not sure about the settings especially the Power Limit (%). I am curious if I need to change it in addition to the Voltage (mV) settings or what? The image shows what I have and am stable at with no hit to my productivity. Opinions?

@JoxNiceHash you or any of the NiceHash crew on here might have any input on this?

Any GPU I use will be 80+ Gold rated or better.

EDIT: (to add) I don't have the GPU yet, I will use EVGA, Corsair, Thermaltake, Seasonic etc at the above rating. Just what ever I find at the best deal when I buy. Just wanted to make sure that 80% usage was a good place to be for this.

Thats what I was thinking, thanks for the verification.

Just got into this mining thing with NiceHash on my daily driver computer and really enjoy it. I am planning to build a rig with spare parts I have laying around, one of which is this motherboard:

https://www.newegg.com/Product/Product.aspx?Item=N82E16813157477

I plan on building an open air rig with risers and will get my GPUs whenever/wherever I can as they become available at a decent price.

1. How many GPUs can I comfortably run off this mobo with the A10-7890K CPU I already have in it?
2. Which riser cards/cables are ideal?
3. Is 80% PSU ratio the sweet spot or should I look for a bit more extra power?

I have tried running NiceHash 2.0.0.6 as two instances with different permissions in all variations, like I am with the 1.xxx version but can't get it to run more than 10 minutes without crashing.

All I am thinking at this point is maybe my PSU can't keep up or my RAM speeds on Ryzen are somehow a problem.

I am using this GPU:

CORSAIR CX series CX500 500W 80 PLUS BRONZE Active PFC ATX12V & EPS12V Power Supply

The thing I am thinking about the RAM is that my 3200Mhz Kit is just running at 2133Mhz. Not sure if that would have any thing to do it?

Thank you! This worked for stopping the Memory Alloc errors, still trying to figure out the 3rd party miner issue tho.

No joy! Using /dev/urandom's idea of two instances I got the Memory Alloc errors to go away by using the CPU on the elevated instance and miners on normal permissions. After using DDU and installing the 16,12,2 drivers I tried running both CPU/GPU as one elevated instance, running both as a regular instance, running an instance for each with both instances elevated, and running the CPU elevated with GPU normal. Every option with 3rd party workers crashes within 15 minutes.

Any other thoughts or ideas?

I get a crash with admin privileges even with 3rd party miners disabled. The only way it don't crash is regular privileges and no 3rd party miners.

I will try the second instance method to see what happens.

Thanks for the info, that at least explains why the Admin privilege works. I do have the permissions set in gpedit.
Any idea why the elevated command would cause the crashes even with out the 3rd party miners running?

Thanks, I'll try this and see what happens

First problem is I get this error set every time I start xmr stak cpu miner:

The second issue I have is that 3rd Party miners black screen crash within a couple of hours but the regular miners run fine with no problems, just less profit.

What I have tried so far:

My paging file is set manually to 32GB max which is my RAM size.
All optimizations and setting I could find here, on github and various mining sites.
Verified that my System is not crashing due to heat.
If I run NiceHash as administrator I do not get the Memory Allocation Errors but it black screen crashes in less than an hour.
The few Blue Screens I have got are irql not equal or less than caused by atikmdag.sys
My memory passes a full run of Memtest 86.
I have tried AMD Drivers 17.6.1, 17.4.4, 16.11.5 and 15.11.
I have tried running NiceHash as admin with and without 3rd party miners and it always crashes within the hour. As stated above if I start NiceHash with normal permissions and no 3rd party miners it runs fine just at half the profit margin (~$4 a day instead of ~$7).

Anyone have an idea on what to try next?

Nah, the CPU I quoted was a mistake, I was thinking the A10-5800K was a 6-Core http://www.newegg.com/Product/Product.aspx?Item=N82E16819113280
but it is a four-core. Which at ~$129 is probably what I'll use.

The 8-core was in reference to the FX-8350 which looks good to me for ~$200 if I decided on a dedicated CPU instead of the above (not likely at this point).

I am not planning to use the unit for multiple operations at once, I am looking at the options I have other than mining when building the rig. The "rig" must be usable for other things (at different times) for me to justify the investment. That may be where there has been some confusion in this thread for which I apologize.
The best way for me to explain it is that I am looking to put around ~$2250 into this rig. I am going to run it as a miner for BTC initially and see how that goes, if/when the ASICs make this irrelevant I plan on mining LTC or TerraCoin, which if I understand correctly can be done on both the GPU/CPU with the right miner software. Now if I decide to quit mining or want to go to an ASIC in the future, I can either dedicate the rig back to BOINC or I can remove one of the 7990s from this rig grab another CPU and have two pretty nice rigs, one for gaming/video encoding and one for BOINC/CAD work. This would work real well especially since I don't use CAD enough to take away from BOINC. Hope this clarifies my intent!

Of course any further discussion is welcomed the more input the better. 

Thanks for the input! I am probably going to use an AMD 6-8 core processor to start with considering that they are realtively cheap and have a good general utility for the cost (of course with an open system design such as test-bench, this can be swapped out on a whim if a more powerful CPU is ever needed for anything). RAM, being one of the cheapest components, I was looking at 8GB minimum which also adds to the multi-use aspect. I will also check out the Corsair you recommend.

That hashcat looks pretty cool, I had not seen that before. I am hoping to get back to BOINC at some point, I would really like to have three to five rigs to cover differing specialties at some point i.e. a miner, HTPC, BOINC, General Use, but that is not happening anytime soon which is why multi-use is important to me.

My first post and several after have made it clear that I have never looked at this from strictly a ROI position. Yes I want the latest and greatest GPUs for multiple reasons. One is that these are excellent for mining as far as standard computer hardware (non-purpose specific) can be anyway. These GPUs can be used for several years to come regardless of whether I mine or not. I am sorry if my reasoning was not clear but this whole thread has been about acquiring the best current equipment for mining but that also has other uses. Right now I plan to start with two 7990s as soon as I can get them, these will be used to mine twenty-four seven but if the introduction of the ASICs increases the difficulty levels to the point that BTC mining becomes outdated with them then I can use them to mine LTC or TerraCoin. If I grow bored with mining then I still have to kick-a** GPUs I can use in various methods. It it more about usability that profitability. Do I wanna make lots of money mining? Yeah, who doesn't! But its not important! Does that make sense?

There are other alt-currencies to mine, I also use programs such as BONIC for distributed computing as well as video encoding and other more basic uses of such GPUs. ROI is not my primary motivation for mining *coin, I like the concept and want to help with the development of alt-currencies. It is similar to crunching data for cancer cures with BOINC, while mining does have the possibility of monetary payback its more about the work than the profit.  Three sources for a GPU at a given hour or day does not determine that those cards cannot be had for less than $800, you reference one scenario with someone needing money which is one viable method of getting the GPUs. There is also those that want the latest and greatest like the Titan GPU or the upcoming 8000 series Radeons which will gladly dump the 7990's to get them. Of course there are also those miners that have moved or are moving to the ASICs, when they determine that the equipment performs correctly there may be a few of these high quality GPUs and complete rigs find their way to the market as well. Its not about instant satisfaction or the need to gain a ROI within x number of days. There is no such thing as impossible! 

Thanks for the info and well wishes!

The method to that madness has basis in primarily four points. First, those $800+ GPUs can be had for less if one plans and researches before purchase. Maybe not a lot less, but can still possibly get them for cheaper than average. Second, those GPUs have uses other than mining so for that reason I think the investment is better than with a purpose-driven system like the ASICs. Third, the ASICs have yet to be obtainable in a determined timeframe and have an inflated cost of acquisition which will level out after the rush is over. Fourth, purchasing 2-3 Jalapenos for around $500 with ~10Gh processing is one of those give it a try things, if the ASICs have a few alternative uses other than mining then I could see that but if they do I am not aware of it. Of course I am new to this and may not completely understand what the ASIC can and will do.

I understand your logic concerning the power versus cost of the various ASICs but for me these are still in the "maybe" stage. We read a lot about them but there is nothing I have seen that makes want to jump on that particular bandwagon at this time. If the theories about these machines prove to be accurate and they alter the process of mining in the manner most believe they will then yeah I will be looking at the 60Gh model at that time.




Thank you for your reply, mokahless! I like many of your suggestions, the use of a mid-range CPU does give one more options of what to do with their rigs if he or she quits mining. If I am investing several hundred dollars into GPUs I have no problem spending $50-$100 more on a decent CPU which gives me more possible uses for my investment. That is also why I like the open rack-style mounting system you reference, it makes swapping things out much easier as well as easier to cool because of greater dissipation and airflow. The one thing I disagree with is the use of Linux, I have used a few *nix flavors and personally I am not impressed enough to switch from Windows. I would like for you to expand on your belief of better overclocking through Linux though, I am not sure how the OS would really make a difference here. Of course Windows needs more resources to run than any typical install of pretty much any *nix OS, that is the only way that I can see the benefit.
