Wow nice project mining man,.. i hope some day can do it like you . And i think that configuration good for low cost, and as far as i know your hardware especially your mother board is very cheap and good product. And thank you for your post/tutorial.

Thanks for the info sundownz - you're a champion.
The hope so too MinersRus. I just assumed that as the plug fit it would be compatible. The 'expert' in the shop who sold me the PSU also told me it would definitely be compatible with the XW4600

That 'expert' should then be liable in refunding you if either the Power Supply and/or the motherboard is now bad.

Finally got some air-flow in the mining area of my warehouse.
5x 24" fans feeding in through existing openings... and 1x 42" fan feeding out through what used to be a window.
I may end up adding another 42" exhaust fan but I will have to knock out some block for that one.
I am garage mining here in the Dallas area and am interested in the ambient temperatures your miners are seeing at the high peak of the day. That usually is around 5-6 PM. I have a full house attic fan in the garage that exhausts the heat from the garage ceiling into the attic which has ridge vents for the attic heat to escape. Currently the garage door is opened about 4" to let in cooler air. That cooler air is getting hot now that summer is approaching such that at the peak of the day I am seeing 95 degrees at the intake to the R815 servers. They seem to be running okay but of course the fans are spinning very fast. If possible could you supply the ambient temperatures at your rigs that are in the hottest area at the high peak of the day. I have on order four WindeeVents that I will put into the garage door so I can keep it closed yet have air intakes. https://windeevent.com. Yes I will take and share some temp readings when I get back in there after the weekend =) ----- On another topic -- I did consider re-pasting all the heat-sinks of my R815s... I did take one heat-sink off out of curiosity and the paste was like hardened mud or something... definitely past it's useful life-span. Before I go crazy and do them all I need to see if I can monitor the temps in UBUNTU and do a before / after one just one machine.

Hello, I am more interested in your published comparison. How about the daily income? How long can the investment money recover my principal?

Looks like a great device for temperature and air speed testing.

Hi Sundownz,
I have purchased the cable you recommended, however unfortunately I still get the same red light and “beep, beep” noise.
Is there anything you can suggest that I might be missing?

Profits were a lot higher back then too, though...

I am working in IT and that means lot of spare computers and free electricity. Setup two HP Elitebook 800 pcs with rx580 and yes keep it running until the GPU dies.

The beep can indicate other hardware issues -- such as a bad power supply. Are you certain the PSU is good ?

The beep can indicate other hardware issues -- such as a bad power supply. Are you certain the PSU is good ? I'm not sure even if the original motherboard he has is still good. https://bitcointalk.org/index.php?topic=1955358.msg37523586#msg37523586By attaching the EVGA Supernova G3 750W power supply to the HP XW4600 motherboard and Powering ON this is what happened:
You essentially shorted the +12, +5 and +3.3 power from the EVGA Supernova G3 750W power supply together because the HP XW4600 motherboard expects +12 Volts on pins 12 and 23. The ATX power supply has +3.3 on pin 12 and + 5 volts on pin 23.
Also the -5 volt line of the EVGA Supernova G3 750W power supply was shorted to ground because pin 20 on the motherboard is ground whereas pin 20 of the EVGA Supernova G3 750W power supply is -5 volts.
You need to test the HP XW4600 motherboard with it's original power supply to see if it still functions.

What hashrate would I get on CN Heavy using an Opteron 6272? I could have swore I read it in this thread somewhere, but I can’t find it now. Thanks!

On quad 6380s I only get about 1050 H/s. A single 6272 I would assume would be 220H/s or so on heavy, perhaps even less.

I’d ran across an 8x6272 server and was wondering if it might be worth it. I found the original thread I was referring to... somebody was getting 2000hs out of 4x6276, but that was old CN before the forks. Was hoping to get around 3000hs out of the 8x, but guess not.

Curious, how much power are you pulling and did you have to customize the electrical wiring of the warehouse?

I see the system you are looking at. Be careful. That system is actually four independent dual 6272 servers in one 2U case. https://www.ebay.com/itm/Supermicro-Server-2022TG-HIBQRF-8x-AMD-Opteron-6272-2-1-GHZ-128-CORES-128GB-RAM/202318902893Look at the picture of the back and you will see 4 VGA ports. One on each dual 6272 server. You can also see one of those dual 6272 server modules being pulled out in the final picture.

For those who are interested in mining on quad Opteron Servers this might be of interest: Dell PowerEdge R815 SFF 2U 6-bay Barebone CTO Server 2x 2.5" Tray, 2x 1000w PSU https://www.ebay.com/itm/Dell-PowerEdge-R815-SFF-2U-6-bay-Barebone-CTO-Server-2x-2-5-Tray-2x-1000w-PSU/122964328060I picked up two of these earlier and added Quad 6234 Opterons into each of them along with a single GTX 750. The above systems come with heatsinks so all you need to add is the Opterons and memory. NOTE that these need 4 sticks of memory for each processor. I installed 16x 2GB PC3-10600R 2Rx8 memory for a total of 32GB for the system. If you use less than 4 sticks per processor the system complains. I have Ubuntu 16.04 LTS Desktop installed on a 16GB USB stick in the internal port. Compiled and running XMR-Stak for Monero7 I get 1560 H/s on the four processors and 240 H/s on the GTX 750 for a total of 1800 H/s. I am local to the seller so the R815 only cost me $230, the four 6234 Opterons $87, 16x 2GB memory $37, GTX 750 $38 and $4 for the 16GB USB Drive. Total of $396.
