perhaps the potatoes are throttling due to poor air flow? try better cable management and a few delta 5000 rpm fans (be sure to strap the potatoes down 1st).

has anyone tried them mashed yet. maybe its surface area that determines hash rate.
4183  Alternate cryptocurrencies / Mining (Altcoins) / Re: Ethereum mining Windows 10 Stability issue on: October 04, 2016, 10:47:20 AM
About windows 10 auto updates I have read somewhere that there is a work around, it is enough to put internet connection as meter one,  then windows won't auto downloads and install those updates... (not sure if that works tho).

it does. got the wifes win 10 notebook set to that, it hasnt done any updates for months, although it does complain once in a while.

I must say Linux is better in terms of running constantly I have run  stick miners for 150 days in a row.

my ubuntu 15.10 basement miner has not needed a reboot for months now. set to never update for any reason. i just install newer versions of claymores dual miner as needed.

might as well choose the same number for this last one as i used for my first one..

+5.5 = vapourminer

thanks phil! this contest is/was a blast.

the cards may draw up to 75 watts per molex, so two would be 150 watts per string. this is generally what is considered the max for a string. so 4 cards, two per string with the molex connectors. for more cards you can use a sata to molex adapter but again only two per sata string.

The other thing that I was wondering about was the 8 pin (6+2) power cables that plug into the top of the GPU's. For instance, I know that I certainly need to connect this 8-pin to my on-board GPU in slot #1. But, will the other 3-4 GPU's connected via the USB x1 to x16 adapters also need this 8-pin power connected?  If both these and the molex are required for each of the off-board GPU's, will this increase to total power draw per card by a considerable amount?

I run one card per string using molex directly connected to the riser, no sata connector between because they tend to get hot and melt. My cables dont even get hot this way.
I do this on my 470s + 480s rigs.

one per string and direct molex to adapter is certainly the best option but its hard to find psus with 4 or more strings of molex, or else im not looking hard enough. biggest i have is a evga gs 850. maybe 1000 watt or above psus?

or maybe 2 - 3 cards direct to mobo and 2 or more via adapters to x1 slots.

I did want to clarify something you mentioned before about the 4-pin molex/2-per string comment. I just inventoried the cables that were included with my PSU and I have 2 with molex connectors... 1 has 3 and the 2nd has 2.  So, what you were saying is to ONLY use a max of 2 per string, correct?  This should work fine since I will at max have 4 off-board cards, so I will just leave the 3rd molex empty on the cable that has 3.

the cards may draw up to 75 watts per molex, so two would be 150 watts per string. this is generally what is considered the max for a string. so 4 cards, two per string with the molex connectors. for more cards you can use a sata to molex adapter but again only two per sata string.

For instance, I know that I certainly need to connect this 8-pin to my on-board GPU in slot #1. But, will the other 3-4 GPU's connected via the USB x1 to x16 adapters also need this 8-pin power connected?  If both these and the molex are required for each of the off-board GPU's, will this increase to total power draw per card by a considerable amount?

each card needs the molex and all 6+2 sockets filled.

some motherboards also have a molex socket on the motherboard, probably near the slots (gives more power for the slots) but i dont think your motherboard has one.

yup, use more x1 to x16 adapters in your x16 slots. a x8 in a x16 will work also.
4188  Alternate cryptocurrencies / Mining (Altcoins) / Re: My new XMR+ ETH thread builds info and other stuff thoughts and photos included. on: September 30, 2016, 10:56:03 PM

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


for mining you dont need a x16 to x16, you can plug a x1 to a x16 with no performance loss. mining takes very little bandwidth and one pcie lane is all you need.
4189  Alternate cryptocurrencies / Mining (Altcoins) / Re: My new XMR+ ETH thread builds info and other stuff thoughts and photos included. on: September 30, 2016, 10:51:11 AM

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.

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.

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

http://www.ebay.com/itm/like/121285554408?lpid=82&chn=ps&ul_noapp=true

 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.

you need very little bandwidth. i have 1.5 megabits per second and have no problems.
4191  Alternate cryptocurrencies / Mining (Altcoins) / Re: PCI expansion question on: September 29, 2016, 11:47:04 AM
?

thats the wrong adapter. you would want pci to pcie adapter, like this:

http://www.newegg.com/Product/Product.aspx?Item=N82E16815158190

not really worth it imo but you should be able to use them in the pci slots on that motherboard you have now. you would also need risers in a open build (ie no case) to run that as the adapter is 1/2 height and you would not be able to use a pc case.

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

i doubt that even miners are running full node.
most of them are doing pool mining and receiving their payment in their exchange address and dump just as fast.
i used to mine to an exchange but now run mist and use it to receive eth from mining. not running it full time but once every few days i will run it just till it syncs and i can see my payments, then its shut down. so much for being a node, even a chintzy one, full time, not worth it.

i do this mainly so i can have a minimum amount of eth for the long term and the lulz, the rest i sell as soon as i mine em. probably 1/4 i keep and 3/4 i sell.

it is possible the password is written down somewhere but its also possible that only hints that would make sense to the owner of the wallet are written down. that way even if bad actors find the hints it wouldnt help them with the wallet.

those hints also might help the family but they would need recognize the hints (which may or may not make any sort of sense) as a lead to the password.

So while I did not want to run any more threads it looks like the universe has a different plan for threads then I did.

So one more last thread.  Wink

did you really think you would get out of the contest this easily?

heh probably there will no correct guess till late 2017 Smiley

i have run cgminer on vista.

cgminer needs zadig to communicate to asics. did you install that?

If you build them, we will come.

heck even if he doesnt build em we are either already here or will be.

My gekko sticks are the only miners I still have running.  Cool
