Topic: Sixth alt coin thread I forgot to mod last thread. - page 123. (Read 80191 times)

I started working on it last night - just back from my overseas travels.

In BIOS, enable 4G support.

In smOS... PCI slot 1 doesn't seem to work - it could be because I am using P106 to test.

However in Windows 10, all slots are working except for slot 1 - my guess is that its expecting a normal GPU with video-out - will test this shortly.

Will post updates today.

I hope Phil got his package soon too.

@citronick, is there any menu with you Onda D1800 mb? Mine came without it and now the second and third pci-e slots just do not work. Any idea?

 Try setting it for 1 thread per 2 MB of cache, that seems to be the sweet spot for XMR mining on CPUs.


 To an earlier question - I try to keep my GPUs to 70C or less when the ambient is in the 80F range.
 I plan some "rework" of my cooling setup in the current place over the winter to get more airflow through it, and intend to add a 3'd evap unit as well (currently running a pair of Brisa 3004 models "stacked" and have enough room and the proper electrical setup to "stack" a 3'd unit on top of the existing 2).

 Most (possibly all) current ASIC miner models have a 200-250 CFM cooling setup. The ones that use 2 fans in a "push-pull" setup do so to deal with high backpressure, doing that improves airflow SOME but is still only going to max out at the airflow rating of the HIGHEST airflow fan.

thanks for the ideas.

I could use a piece of foam and wrap it in fiberglass blanket. lay it on the psu's then  the tunnel  would be sealed from intake and exhaust.

I wonder if that  would be an improvement on temps of the gear.

Profitable ASICS = S9s or A741s, L3+

Avoid X11 miners because there is just too many D3s, Baikals, iBeLinks out there -- and the diff level is basically screwed to kingdom come. Hopefully something good will come out of X11 coins in near future.

If I can turn back time, I would have bought shitloads of 470s and 1070s for the ETH farm.

A good benchmark from Nicehash as follows:

Nice piece of furniture you built there. Looks strong enough to act as a butt warming bench!

I would add a roll of some insulation material and place it on top of those PSUs to block off the back-draft airflow. That way the ASICs and PSUs would be able to pull fresh air through the inlet air filter much easier. Try to compare the overall airflow with and without the blockage by watching deflection of some sheet of paper or something. Also interesting to see the differences in temperatures with/without filter and/or the blockage.

What's the total airflow of both ASICs and PSUs? 300-400 CFM I guess?

10dB SPL reduction is pretty good. To make it even better you can try and add some baffles in the U-channel and build a labyrinth of sorts. That way you may get another 10 dB reduction easily and still allow for decent airflow.

I would also measure your static pressure by sticking the tubing from a simple manometer into the space in between the ASICs intake and the intake air filter:

I am seriously thinking of buying some ASIC's instead of repurchasing GPU's to replace all the ones i lost in the hurricane damage.

Since the L3+ seems to be on infinite backorder unless you know someone or willing to pay to much, is the S9 worth buying right now or just better off waiting? i know very little int he world of ASICs right now...

If anyone wanted to know i assembled my new gamer/personal PC today, AMD Threadripper 1950x, in Awesome Miner benchmarking for CPU mining on XMR using, it averages 1,387 hashrate @ 128watts, not sure why it only says 50% load on all the cores... maybe tweaking is still needed.

just tell them it started to smell burnt as soon as you powered it up.
don't mention mining don't mention risers..  it is a case of less is more.
i.e. do not volunteer  extra info.

I plugged it into the pc I  powered it up and it smells burnt is enough info.







yeah me too but  I did get to work on the you tube channel







This you tube channel will show how to have a garage mine.  I use 1x 30 amp 240 volt circuit connected to a 24/amp pdu

Yes riser is possible, or bad plugging.
EVGA will accept it without any problem.

Hi Guys, sorry for off topic, but would anyone know how to avoid the "stuck trouble" with Stak XMR miner ?
Because on some rigs, STAK doesn't want to work after about 10 minutes. No error, but I see in the console that the last share was long ago, generally about 10minutes after the miner start.

That's very annoying, and I don't know the cause.
I'm forced to switch to sgminer on that rigs, or claymore ...

Friend of mine has been setting up a rig... One of his GPUs started to emit a burning smell right off the bat. Probably riser related. Can a faulty riser actually physically damage a GPU? I suppose it could if it's shorting it somehow. Would EVGA accept an rma for this type of damage?

My guy in China says his supplier got stocked out and waiting for next batch.

Sounds like the great whale has bought all of it.

I am going to another channel direct to a Colorful distributor... keep fingers crossed.

Ugh man I hate risers so much. Why do these things suck? Did anyone get their hands on that new color master extended length board or whatever it was?

I first started using low temp hot glue sticks, they didnt melt on the gear, but seemed very soft during peak heat of the day.. so i bought high temp sticks and a new gun..

These are the sticks i bought

This is the gun, it was clearance for $0.99
https://www.hobbylobby.com/Floral-Wedding/Floral-Supplies/Wire-Tools/All-Purpose-High-Temperature-Mini-Hot-Glue-Gun/p/157112

In regards to using it, i just firmly assembled everything, booted it up, made sure it worked, then i turned it off, unplugged the power and wiped everything down with rubbing alcohol and rag and just gobbed it along the entire PCI connection, multiple passes, then gobbed it around the usb connector, then around the 6 pin connector, then i hit up all the backs of the connectors at the cables securing each one in its own gob of glue, then on the mobo, i pluged the adapter in and gobbed it on the mobo...

In my case, most of the issues i had were the riser PCI to GPU connection, i used a white paint marker once to test it out on a rig i assembled, and every gpu moved some at that connection, none of the paint marks lined up perfectly anymore and i had zip tied around the riser and gpu on that rig, still the viberations from the fan and such made it slowly move.. with the hot glue i place it everywhere so it cant move...

Maybe if you want to, try silicone, i just went with hot glue because it was cheap and already had it at the time.. just upgraded to the higher temp stuff after started using it...

@storx - how do you apply the glue from a glue gun - i have been contemplating getting one  so that the risers and slots don't move about - I usually end up coiling the USB cable to tighten the contact but this I think will make matters worse. Any good bran - glue gun and glue cartridge?

@philip - anxiously waiting for the mobo to arrive in your good hands.

Still waiting for the mobo. It arrived in the states on the second.

May be lost not sure the Singapore mail  service says it reached the USA

USPS says it is not traceable.

I think if it went to west coast USA  from  Singapore that it arrived on October 2nd.

It is the 6th so maybe it comes on the 7th or 9th or it is lost.

Ya, i have to agree with you when i was 100% operational before the hurricane, running the cards like a skank on the street is just not worth it.. sooner or later it will stop putting out.... I personally sacrafice a little in the hashrate department and create a custom fan curve that keeps all my GPU's below 69c no matter what... I have the mining settings setup to pause mining for 60 minutes if there is ever a time a card ever exceeds 72c, which happened twice and both occasions it was because the MSI Afterburner software had locked up on the machine and stop controlling the fan curve and defaulted to OEM fan curve, both times it happened the software SMS me that it happen, i looked into it and fixed it... My very first 1080ti GPU i ever bought for mining, i didnt really know what i was doing, had it mining at default 84c @100tdp for weeks, that card now is my main GPU in my personal desktop now, because when it mines the hashrates are only about 80% of exact model cards, because i ran it to hard from the beginning and it always mined in the 80ish range for days...

The main issues i have ran into is Riser issues, mostly from expansion or viberations making the connection not as secure. I fixed most of those issues by investing in a hot glue gun, now when i install a GPU in a riser i gob a few sticks of glue around the gpu to riser connection and on every wire connection, to include the pins entering the back of the connections... this alone has dropped my riser issues by like 95%

Just a guess but you could check your BIOS for M.2 options – there might be one for number of PCI lanes or speed eg x2 x4.

well I would say  my cards never fail 100%  worked from day one  until I sold them

this would be all the

 rx 470's
 rx 480's
 1080's
 1080 ti's
 1070's

from the beginning of these threads last year  I have had over 120 cards  no fails.

other then when I stuck a riser in the wrong spot and fully shorted a new asus strix 480 gb

  but  I never run  over 80c  ever.
  i try to run  65-70c
  I sell all cards under 1 year of use.

now  of all the cards I sold  3 guys got back to me they  had killed off the cards  1-4 months use  and I got multiple rmas for them.

So  base on rx 470's up to  nvidia 1080ti's

they all should last a year if you don't push them.

that 120 cards is ball park  but not far off. maybe 160 cards is closer.

most miners push  till  the card dies and don't sell the cards off.


also never had a fail fail but my locations are not dusty  and fans are 75% or less.

I have had  4-5 riser fails
1 mobo fail it killed 3 psu's
4 psu fails
0 ram fails
1 cpu intel 6700k failed


all in all my style of 65-70%  is working  for keeping gear safe.

What are your ideal target temps for cards? (realistic)
+ whats a temp range you consider too hot for the card // why and how long until (estimated) the card will fail?
