Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH - page 131. (Read 451266 times)

it's gold i belive, but one of the drawbacks is it's coolers which consumes ~70W at zero load.
no point in using such a powerfull PSU with only one S5. 3 is good load for it.
i will test it with S5s later this week also i plan to disable some of it's fans.

Thank  you for hanging in with us during the RMA process.  Hope our fast domestic RMA helped you ease the pain a little.

for others, if you need RMA, or its too hard to trouble shoot, please use the Warranty Center in Denver, Colorado to get the diagnostic and usually the same day turn around service.

Happy Mining!

Thanks again Bitmain, the two S5 arrived about an hour ago!  Swapped the push fans and have them up and running to check them out before moving to CGminer 4.9.0 and 312.5MHz.

Have decided a push S3 fan is fine, but adding one as a pull makes it a little loud.  Would like a quieter pull fan.  Am considering the Silverstone FHP141 (per Philipma1957), however, it isn't PWM, just dual speed with a PWM connector -- would definitely prefer PWM.

It was great getting the news that my S5 shipped before the 30th. However mine is being held up in customs. Fedex is asking for an FCC form 740. Any help with this would be great as I don't know any of the information they want on the form.

so i've gotten myself a poweredge AHF-2DC-2100W power supply... does anyone know whats the efficiency (80+ gold? plat?) and power consumption on the wall for a single s5

I think his WTF is from the fact that buying bulk for a later batch, is more expensive than buying individual for an earlier batch.  Given some of Bitmain's earlier statements with regard to how they price their items, this situation would appear to be counter-intuitive at best.  There's no stock indicators though, so if the March batch is almost sold out, and anybody wanting to buy a bunch of them is pretty much relegated to the June batch, then the higher price might make some sort of sense, especially with regard to lack of competition from the March batch.

In an unrelated thread somebody at Bitmain suggested waiting for a newer chip from them, have to wait and see what they produce with it though

That's what lack of competition will do. Bitmain claim's this is their last run of s5's. I hope they have something in the works for the next generation or mining will be hard for the average joe.

What the f***?

Not too worried about it, my overall hash rate is outgrowing global hash rate by reinvesting in miners.

Not to mention btc dropping below 250 again may impact hashrate

All these new S5 batch are getting powered up and difficulty is going to high new highs. Sucks for anyone who bought new hardware this month

44-45C does feel like slightly worm, but not hot.
I have no idea about anything else but EVGA 1300

what is keeping you from using those molex to pcie adapters on 2 of the plugs?

I just had a thread in the Hardware section about feeding one pcie cable over 300w and although they can do it if you watch them, IMO it's just too much for safety concern unless you run aftermarket heavy duty cables and a very good power supply.

I was running 600watts through a Thermaltake 750W gold with 2 pcie cables using 4 conenctors. Almost 300w each cable.
The cables started getting warm to the touch after an hour or two. The cables are ribbon 18awg stock cables.


I'll try the same with my evga 1300 to see how it handles the same.

It is totally fine (for regular speed). I run them more than two months like that. I connect two doubles (with two connectors each) to one machine and four singles to another with each single double cable feeding one board (side) of the miner, although others use a different architecture. I also checked with a laser thermal probe and cable temperature never exceeded 42-45C. Connector temp also never exceeded 44-45C (with 28C ambient). If you are concerned about temp-get the laser probe-I liked to play around with it.

It's 6 cables, but many people have had success pulling the ~275W per blade through a single cable using the two ended cables. It's still modular so you'll be pulling over 22A at the connection between the PSU and cable and that's pushing it, but it's also the cool end of the cable. Run the two individual cables to the board that powers the controller and fan, and the double headed one to the other board.

If your ambient is high, I wouldn't push it much with overclocking. Mine pulls ~700W at the wall running at 400MHz on a 1000W Platinum supply, and that's pretty boarderline through a single connector.

That's 8 cables. Eva 1300 has 6.

They should run cooler with no internet because that will stop them from hashing.  I wonder what makes some heat up when they're not doing any work?

2 x 6 Pin PCI-E

My RM850 took a dive on me. There is a known bug on several batches of them that will randomly pop a capacitor and the fan will never work again which will overheat the PSU. I sent it back to Corsair for replacement and they didn't have any stock to send me one back. So a week later I called them to "complain" a little bit and said if you can't give me a replacement PSU can you please refund me on what it cost or send me another upgraded model. I lucked out and they are now sending me the HX850i model. One of their high-end models.

This applies to ALL RM series power supplies. Too bad Corsair is still shipping these knowing there is a problem. I'm thinking of stepping away from Corsair products just because of that.


It's been confirmed since last year that any RM series that's shipped out with a lot number below 1341 suffers from a defect of the fan not spinning resulting in the OTP tripping.
This has been confirmed by corsair rep themselves.
If you DO have one of these models, judging from the thread they're still shipping out the older ones, either return it to Amazon and roll the dice again or contact corsair and they will send you a newer model with a prepaid shipping label!
Please note this issue is generally caused by ppl with rigs that use less than 50% of the psu power.

evga1300 has 4x1pcie + 2x2pcie
use 2x1pcie + 1x2pcie for 1 antminer s5 and it will be ok (1x2 pcie connect to 2 boards, one single pcie to first board and second single pcie to second board. Do not connect 1x2pcie to 1 board and 2 single pcie cables to second board)
