Asus Strix Disconnects

[Icarusfixius]

Every time this machine reboots the strix is missing form the card list, only 5 show up in device manager. If I swap the riser usually it is recognized again. It doesn't make any sense to me that a card would repeatedly kill risers. Does anyone have any idea what may be causing this issue.

you flashed bios and fucked it up  it draws extra power through the riser.

you over clock like mad trying to get every piece of hash  and that card while perfectly fine for say small over clock pulls power like mad on an overclock

look at the two card rigs same cards as you.   and one set works at higher clocks one does not.

still yet another reason to have multiple smaller rigs rather then the massive six and seven card rigs if you have under say 18 cards.


I binned and sorted my asus strix


BTW a powered riser = 10 bucks you burned 2 so far.  so two three rig setups  are looking more and more like what you needed to do.

Philip,

Thanks for taking the time to respond. none of my cards have flash bios's or have been overclocked at all. All RX470's running at factory settings aside from fan speed which I have sped up. I would consider doing smaller rigs though it seems that most user risers with 6-7 cards each no? Just trying to make efficient use of all the other hardware.

properly re-paste that asus card as well;  if you have ever accidentally put too much pressure on the cooler in the wrong way, the cooler will flat out lift off the die and screw up the paste job.

it is not efficient to do six and seven card rigs  if all you have is one of them.

How many threads do you see my three card rig is fucked up

vs my 6/7 card rig is fucked up.

That doesn't make any sense at all. 6 cards in one rig beats having them in multiple rigs.

only if the single rig works correctly.

only if the psu does not fail

and only if one coin is good to mine. both zec and eth are good to mine at the moment.

2 three card rigs  allow for mining zec on one and eth on the other.


2 three card rigs allow for a three card nvidia rig for zec
2 three card rigs allow for a 3 card amd rig for eth.

if you want to try to run 1 six card rig with 3 nvidia and 3 amd and say a zec miner and an eth miner all at the same time have fun getting that to run weeks on end.
I get my smaller zec nvidia and eth amd to run weeks on end.

three card rigs can be run quieter with less cooling issues.

and three card rigs can use a 750 watt EVGA p2 .

also if it is the winter  and you need heat the two three card rigs  can be in two different rooms going them heat.

so like I said if you run one six card rig  it is not the best way to manage your mining.

two 3 card rigs are better.



if you have a lot of six card rigs  2, 3 or more  this does not apply.

I think efficient may be the wrong word to use.  Using multiple smaller rigs can reduce you failure domain, since the cards are the only thing that makes you money, but also increases the number of parts to troubleshoot (motherboards, CPU, power supply, etc).  I've run two 6 card (GTX1070) rigs flawlessly for months, but I was very methodical about what parts I used and how everything is wired up.  I do agree, as little overclock as possible is the best and undervolting/reducing tdp is good as well to keep things rock stable.  I would rather have my two six card rigs run 24/7 for months at normal clocks and cool to the touch, rather than burning hot with fans maxed.

If you are burning through risers, you need to deconstruct your setup and look at how you are wiring things up.  Also, if you have pulled the cards apart and messed with heatsinks and paste I'd scrap them and start new.  Never a good reason to pull cards apart, in my opinion, unless they are already out of warranty and you don't care about actually being stable and profitable.  Make sure all of your power connections are solid and not over heating.  Are you running split power supplies?  If so, make sure the card and riser are powered by the same power supply in each pair.  Also you could try swapping the "bad card" to another slot and see if it still burns out the riser; although if you have narrowed it to the card itself, get a new one or send it into repair.

you are a two rig owner  so my statement does not apply to you as much as  a one rig six card owner.


you can point a rig at eth
you can point a rig at zec
you can locate the rigs in two spots.

I am against one six card rig as your only miner as you lose a lot of flexibilty.

Multiple six card rigs can be just as flexible as multiple three card rigs  in the three cases above.

one thing you got right is multiple mobos  mean a  bigger chance of mobo failure.

I had a z87 fail and take out 2 psu's before I realized the mobo was the villain no the psu's or the cards.

All in all mobos are low cost
gpus are big ticket

All true.  I started with a single rig and two cards, and simply added cards till it was full.  Then added a second rig and split the existing cards between them.  Been adding cards to both until they were maxed, and now have parts for a third.  I guess it's just a matter of planning and where you are going with it.  I prefer planning for the maximum up front so it's easier to expand upon as you go.

Regardless, he's definitely got something wrong in his setup.  I would say we need a full parts list to know where to start as it's pretty trivial to run six cards with the correct parts.  If he's looking to expand more in the future, then now may be a good time to setup a second rig anyways which would allow additional parts for troubleshooting.

[Icarusfixius]

I currently have five 6 card rigs. I just have weird issues with this one card. It doesn't add up in my mind.

[jwarren81]

Are they all identical?  Have you swapped that card to a different slot, power cables, risers, rig etc?

[philipma1957]

At the op you have a shit card it has a higher draw at the riser end.
would have helped me a lot to know you had 5 six card rigs. using 30 cards

here is a suggestion

have a tester rig and run that card in a slot on the tester rig.
the mobo I linked


is good as a development rig

https://www.newegg.com/Product/Product.aspx?Item=N82E16813145007&cm_re=gigabyte_b250m-_-13-145-007-_-Product


it will allow you to slot test cards

this is the cheapest quality small mobo I know

you can start with 2 cards in the slots

and later add  more cards with risers

it can do 2 in slots = 3
it can do 2 in slots and 1 in a riser = 3 card

it can do 1 in one slot and then 3 with risers = 4 card

it is a great trouble shoot board

and it is a gigabyte 250m  so it is physically very small
 80 bucks

I put this cpu in it

http://www.ebay.com/itm/Intel-Core-i3-6100T-3-2GHz-3M-Cache-DualCore-LGA1151-CPU-Processor-SR2HE-/322490605689?

paid 91 for the cpu  it will take this one


http://www.ebay.com/itm/Intel-G4400T-Processor-2-9GHZ-Low-Voltage-CPU-Only-Socket-LGA-1151-NEW-/252844237292?

nice psu sale  so 109
http://www.ebay.com/itm/EVGA-SuperNOVA-220-P2-0750-RX-750W-ATX12V-EPS12V-SLI-Ready-CrossFire-Ready-80-/382026031239?

a stick of ram 25 bucks

http://www.ebay.com/itm/Kingston-16-GB-M-2-NGFF-mSATA-SSD-Chromebooks-Acer-/201888633168?

5 dollars for the m2 and smOS is free at the moment

so 80 mobo
    55 cpu
   109 psu plat evga 750 watt
     25 ram
       5 ssd/os

so 274  for 2 card
    284 for  3 card
    304 for  4 card  you need 3 risers.  

now do this with a six rig
85 but out of stock
https://www.newegg.com/Product/Product.aspx?Item=N82E16813138449


85 mobo
55 cpu
25 ram
5 ssd os
229 for an evga 1200 watt p2 or
189 for an evga  1300 watt g2
 60 for siz risers

so 394 for six cards x 2 = 12 cards at 788 with gold
or  304 for 4 cards x 3 = 12 cards at  912 with plat


so even with 2 six card rigs vs 3 four card rigs   the edge just tips to six card maybe not as the six card may run louder and hotter then the 3 four card setups.

you will save watts with the 3  four card card setups.

All goes by the wayside as you expand   but up to 12 cards it is very close

[jwarren81]

Yep, lots of ways to do it, I'm partial to H81 Pro BTC R2.0's myself.  The sound and heat are the reason I love my STRIX GTX 1070s.  They run quiet and cool at 420 sol/s and 125w per card.  I could probably squeeze more but see no reason to mess with a solid income.  These rigs combined with baikals are easily funding my expansion efforts.
