1  Alternate cryptocurrencies / Mining (Altcoins) / Sources to buy RX 470? Suggestion for other Eth GPUs? on: June 09, 2017, 12:09:10 AM
I am not finding any anywhere for their actual price ~$200, only finding ones for double and triple, presumably from the spike in Eth prices.
I have one 6x RX 470 GPU rig for Eth mining and want to build another.
I see a lot of Nvidia GPUs available but I'm not sure which ones (if any) have a working driver that allows 6 GPUs to run together like my AMD setup?
2  Bitcoin / Mining support / help with first time wallet configuration.. on: May 05, 2017, 10:52:51 PM
Hi all - I've setup an a741 and T9, do i just put my wallet address from coinbase right into the UI for each miner? how long does it take for me to verify the wallet and miners are connected?
i just pasted in the wallet address where it says worker: in the miner UI
3  Bitcoin / Hardware / PSU 8pin to 6pin/6+2pin cable? on: May 04, 2017, 06:56:19 AM
I have an EVGA 1600w G2 PSU. I need one more of the cable in the bottom right of this picture:

It is 8 pin at the PSU end, then 6+2 pin, and also 6 pin.

EVGA calls this a "6+2pin + 6pin PCI-E VGA Cable"

I don't want to order a kit of 4 cables from EVGA and not need 3 of them.. I dont see it offered by cablemod either..

edit: feel free to move this to altcoin mining subforum.. sorry..
4  Bitcoin / Mining support / APW3 power cable in the US, where to buy?? on: May 02, 2017, 06:29:38 PM
i have a 240v 30a circuit that isn't being used, but is wired for a dryer. I have an electrician coming to convert it so i can power an a741/apw3 and t9/apw3, 2 apw3 total.
what power cable do you guys use for this PSU?
what would be the simplest outlet/approach to instruct the electrician for conversion?
5  Alternate cryptocurrencies / Mining (Altcoins) / PCIe 1x to 16x Riser Question.. RX470 EVGA 1600 G2 on: April 30, 2017, 11:39:36 PM
Hi All - Sorry if this has been answered elsewhere.. I tried looking.

Can I power the GPUs directly from the PSU using the VGA 8 PIN cable that came with the PSU?
Then I would just need a PCIe extender (ribbon? USB?) from 1x to 16x and done, correct? Do people that use powered risers, do so because their PSU doesn't have this capability?
Also why do some use SATA connections instead of the 8 pin VGA directly? I don't see why to do that given my setup..?
Also what is the purpose of USB risers instead of just PCIe (ribbon?) risers, the transfer rate? Isn't PCIe sufficient enough for the RX470?

Any links would be helpful, there are so many different risers..
Sorry for the barrage of confusion..

6  Bitcoin / Mining support / UPS recommendations for 2x APW3+ 1600w on: April 26, 2017, 09:38:40 PM
Hi All - I have an Avalon A741, T9, and 2x APW3+ 1600w on the way. i'm looking for ~5 min of failover support (enough time to rush over and turn them off normally) and some decent current filtration, even though the brownouts are infrequent and slight, i'm going for longevity. Is it better to have 1x UPS for each or OK to have one big UPS for both? I think i'd rather go with something like APC instead of the cheaper appearing brands?

7  Bitcoin / Mining speculation / 6.4c/kWh... on: April 26, 2017, 05:36:58 AM
Hi All - Sorry if this is a very basic question. I've been lurking for a few months and have ordered 1x A741 to begin mining with after a fair amount of reading. I'm living with relatives on a large plot who are paying utilities. Before I ordered the unit, I was under the assumption that the electricity costs were around 10-11c/kWh, figured that was about the national average. I found out today it's actually 6.4c... What would you do in my circumstance, finding out you have nearly the cheapest kWh in the country? To add, I could get a fair amount of commercial rental space for $200-300/month.. I'm feeling inclined to order 10x more A741s...
