Topic: My second ZEC + XMR+ ETH thread builds info links thoughts and photos. - page 94. (Read 147923 times)

Thanks Vapour & Phil, your comments were very helpful! So, I actually found the x1 to USB adapter piece buried in the bag in came it, so am actually good with that one now (except for the fact it wont fit with a GPU plugged into PCIe slot #3 lol.

As for the ribbon riser... firstly, I just think i got the wrong one because if I was going that route, it seems this would be the one (x16 to x16):

https://www.amazon.com/PCIE-Micro-Express-Flexible-Extension/dp/B00D79EV0G/ref=pd_sbs_147_2?ie=UTF8&pd_rd_i=B00D79EV0G&pd_rd_r=5T5M5AQX9J6XBWWVWFS1&pd_rd_w=9IOqu&pd_rd_wg=wFz0a&psc=1&refRID=5T5M5AQX9J6XBWWVWFS1

... not the x8 to x16 that I got.  But, aside from the fact that you (and others i have seen in this forum) have had less than stellar results with the ribbon risers, I also don't like the fact that they really do limit you to rising the cards directly above your rig, which my open-air rig will not be able to support unless I make some unwanted major additions to it.  I would highly prefer to go the route Phil has and use only USB extenders so I can mount them to the side of my rig, which is much easier than building something to suspend them above it.

The problem is, I cannot seem to find and USB powered risers that plug into a full length x16 slot.  In Phil's 2nd photo above, he has 2 plugged into the Mobo but they are both going into 1x slots, not x16.  Do they even make such a thing?  I searched ebay, amazon & newegg and didn't find any but maybe I am using the wrong search terms.

Unfortunately, I have now come to the realization that the only way I will be able to get more than 2 GPU's running off this board is if I use 4 riser/adapters, so am really hoping I can get a hold of three x16 USB adapters that are similar to the 1x adapter I have, so I can move them off-board to the side and mount on plywood a la Phil's rig in the pics.

So, can anyone recommend a good x16 to x16 USB powered adapter/riser?

Not sure why you would write something nasty when I just asking why you preferred that pool over a "little bit everyday" as opposed to a "nothing for days then a big chunk". Of course your answers explains it well enough.

I was mining on that pool with my small rig, but waiting 20 days for a payout was just not doable  

for the usb based riser the pics in this link show how it goes together.

 you dont want to use the sata to molex adapter, just plug a molex directly to the adapter. max of 2 per string, that will be 150 watts or so per molex string.

to use all the x1 slots all gpus usually have to be on risers as some will get blocked when double wide cards are plugged directly into the mobo.

as for the flat ribbon cables you to linked to

https://www.amazon.com/gp/product/B00H8VVD00/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1

they may work and i used them in the bitcoin gpu days and while they usually do work the adapters with the usb cable are much better  imo. the molex wires deliver power to the adapter better as it uses thicker cables vs the very thin wires in the ribbon cable style.

ethpool is strange unique pool - its not a solo pool but behaves like one paying the usual coins and uncles - its not an "all or nothing pool"

I started my ETH project December of 2015, and build a mini farm around ETH and later a rig on XMR. After trying out solo mining for awhile, and all other pools, I settled for ethpool and ethermine as my main and backup pools respectively.

I really like this combination and get paid regularly. The OP is also active and helpful in the Ethereum forum. Also, I get good stats and monitoring on my Android phone for both ethpool and ethermine. Life in ETH is as good as it gets mining there :-)

  I could write something nasty  but the    the truth is it is not all or nothing.  It simply adds your hash marks up and when you did enough points that you should hit a block it gives you the next block. Frankly if you are getting a block every 40 to 50 hours time after time and once in a while you get a bonus uncle it pays better then any other pool.
  If you have 200 mh it takes about 5 or 6 days

I wanted to chime in again and firstly thank everyone who contributed feedback to my first mining rig build. So, I finally got my heatsink, installed it today along with the CPU, RAM and the 1st MSI 470!  I have yet to do anything with the power supply/cables since I wanted to get the layout built and tested before that final step, but everything including the test bench assembly and mounting/hooking up the SSD & Optical Drive went well.

So... once I realized how absolutely HUGE these GPUs are compared to the MoBo, I now totally get when Phil and others stick to a 4-GPU build lol    I was able to plug in the first 470 into PCIe3 x16 slot #1 no problem at all (no blockage issues, etc).  However, after plugging in GPU #2 into PCIe3 x16 slot #3 (slot 2 is PCIe2 x4 slot, so i skipped that for now as I understand that will need a riser cable), I realized that it actually blocks PCIe slot #4, which is the short PCIe2 x1 slot. From Phil's previous advise on risers for this board, I purchased this PCI-E 1x to 16x riser adapter cable:

https://www.amazon.com/gp/product/B01CU1U2XG/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

The first problem is that the short PCIe 1x slot is blocked. Only an extremely low profile plug/adapter could possibly fit in there underneath the GPU.

The 2nd problem is that I can't even figure out HOW this adapter is supposed to work because even if there were space above this slot on the MoBo, there is nothing in the product above that could fit in this slot. Aside from the converter board itself there is only a 4-pin molex to wide sata power cable (i don't even have any of the wide sata slots on this Mobo, only 10 regular sata) and also a 2-ended USB cable.  Am I crazy or is this adapter even meant to plug into that 1x slot at all? Either way, i cant figure it out so would appreciated some advice.

GPU #3 inserted fine into PCIe slot #5 (the 3rd and final PCIe3 x16 slot). Unfortunately, the GPU blocks a bunch of headers/jumpers, but it seems like possibly none of these will be required for this build (BIOS/CMOS stuff, COM & TPM headers, front panel audio, & USB headers).

GPU #4, which arrives tomorrow would therefore have to go into either slot #2 or slot #4 (already described the issues with slot #4 above, so not even sure that is usable at this point).  Slot #2 is PCIe2 x4, so I got this adapter/riser cable:

https://www.amazon.com/gp/product/B00H8VVD00/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1

But, although the short end of this cable fits within slot #2, there's a lot of empty space since the adapter pin section is shorter than the overall slot length.

Bottom line is that I've never used this kind of risers/adapters before so I figure either there is something I am missing, or, i simply bought the wrong adapters.

As always, any feedback is appreciated!

phil has about 500mhs so he is around 2 day payouts

Whats your wait time for a block? Seems to me if you have less than 500 MHs its not worth it to mine on the ethpool all-or-nothing payout system.

I did not know any better  and I had unreal luck on uncles right away.

I was paid  blocks of 9     3 times  in my first 10 blocks,  basically  that is about 12 extra coins.

Since then  2 more  out of 90  which is normal.

  so 20 coins in total.   I suppose I could do the other way but I like that when ever then send a block to me it could be 9 vs 5 coins

I use hdmi emulator, $15 on Amazon, for my rigs. Rigs act as if there is a monitor attached and allow me to teamviewer in.

Phil,

Why did you choose http://ethpool.org/ has your first choice and not the PPNLS ?

Thanks

Herb

I use VNC for my remote needs.

I just don't want any HDMI cable on the rig as I don't need it. I guess i'm gonna have to buy a fake hdmi cable adaptor.

For now, i have to plug an HDMI in the main card or it stops hashing.

use a kvm here also. switches between a freenas box and a 2 x  r9 3x0 ubuntu rig. sure saves space on the shelf.

When I am physically at my warehouse, I use TightVNC to remote control all my rigs there.

From home, I just do a Teamviewer into my main console in the warehouse and take over the TightVNC access to all rigs.

I have 3 test rigs that I am using KVM at home.

MarkAZ. Did it in his rigs.

I go old school I have Kvm-usb switches and monitors.  I can do 12 pcs with 4 on each of my 3 monitors.
My problem is heat just too hot to run my 28 cards.  I will most likely run 4 four card rigs on one monitor.

noob question,

I have a on board video card which I use to setup my mining rig. I installed one of RX470 until I get my riser.

When I rebooted, the RX470 took over the on board video card. So I need to use the RX as the main video card (guessing some bios tweaking might fix it)

And if I don't plug an HDMI into the RX, the card stop mining.

I'm pretty much going to do some remote desktop from now on, so I think I red about an adapter to fake the cable ?

1. Is the cable/adaptor absolutely required ?
2. Anyway to go around that behavior ?

Thanks

It's not worth it. 500-600 xmr is both cpus included. Tdp on those is 115w each. And that was at 100% CPU usage.
I have them water cooled and ran in the low 70c temp wise
You couldn't roi from xeons. Mobo alone was 450$ cpus 140$ for both

how much on the cpu% used and of course on the watts.   

2 rx 470-480 do about 1000  at 240 watts.  so you would need that cpu to do under 150 watts. please  check math on this though.

I am pretty sure those are the -h values no the hashes per second you will get.

I could be wrong, my 290x never got near 1376 when I was playing with it before the 480s.
