Ok far too many posts - both in the threads and on my profile as well! Wink

Someone was really kind and gave me advice on how to use "TWO" PSU units to power "THREE" S5 Units.

Basically using 2 850s or 2 1000s and then running 3 miners of them.

Does anyone here remember the correct wiring to do so? Is it you simply dont power a single blade/side from two miners?

Sorry; I've scanned through like 20 pages and can't find it - and search is currently disabled.

Thanks!

Just run PSU A to S5 X and one blade of S5 Y, then run the other blade of S5 Y and S5 Z off of PSU B.

That is correct. Only 1 PSU per blade. (Don't cross the streams!) Wink

@suchmoon @Biodom
Thanks! I connected the 2 PCIe cables, up to now it seems to work great. I'll do a temperature check tomorrow.

Now I have to make this fanmod before the wife starts to beat me up.... :p

i did not dare to run it at default for more than 12 hr...
Everyone seem to be particularly affected by the S5 default fan sound. You want to stay as far away as possible.
what's your mod?

I replaced the loud stock fan by two 120mm fans I had in spare. The fans are in push-pull configuration and powered directly from the PSU (constant speed).
It makes my S5 really quiet, about the same as my desktop computer. But I had to downclock to 250MHz (~800GH/s) to keep the temp below 60°C.

So at this point I loose 30% of hashing power to reach an acceptable sound level..
Next step I'll try more powerful fans with the "fan shroud" trick mentioned by dog1965 (https://bitcointalksearch.org/topic/m.10250546

I also noticed a big spread between the 2 temp sensors... Any idea what it could be??

I think they all expire 2/4, and you are right 370 isn't.

they probably have to hold the price so S6 would not look overpriced at 3-4th and $1100-1300.

Does any one have AntMiner S5 coupons that they will not be using?

I'm looking for 2 as well. I emailed Bitmain but they are not giving them out anymore, even though I just bought 2 s5's last week. I was hoping they'd drop the price back down, at $370 it doesn't seem like a good deal.

Has anyone tried any of the power supplies from Super Flower?

I am looking at the Super Flower SF-750P14XE(HX) Golden Green HX 750W 80 Plus Gold Certified PSU for my S5 for when it one day arrives.

Don't use 8-to-6 splitters, get a 2xMolex to 6-pin PCI-E instead and put that on two separate Molex cables.

RM750 and CX750 both come with two pcie cables that are branched-perfectly fine to use for regular speed at total 590W.
I checked connectors and cables temperature with a laser probe and they never exceeded 45C
You will just confuse the OP.

Sorry, I thought the poster meant some kind of aftermarket contraption to split 8-pin PCI-E into two 6-pin PCI-E. Corrected my post.

yea right dogie you still did not explain how to do it because you really don't know.

He heard a rumour ..... and unless he heard it before you, then it'll void your warranty. BE VERY SCARED! Shocked

Agreed he works for BITMAIN maybe this is there way of making more money. If they tell dogie then dogie tells everyone else then they will see a lot of s5 controller boards lol.

I answer 10 of your questions via PM, yet you're still aggressive towards me on here. You PM me a question over lunch, and after 40 minutes you PM me again flaming me for not answering it already. So no, I will not answer your question.

That's because you really can't you don't know the answer and stop fibbing saying you do one you really do not !

I pm you 7 times with no response so your full of it !

Sorry for the noob question:

I'm setting up my freshly arrived S5. Power supply is Corsair rm750.

I keep reading everywhere (http://www.enthusiastpc.net/articles/00002/3.aspx) that maximum power output is 75W for 6pin connectors and 150W for 8 pin connectors.
How can the S5 draw ~500W using 4x6PCIe providing 75W each?
And can I power it with 2 cables of the type 1x8PCIe -> 2x6PCIe?

Thanks

PCI-E specs are quite conservative and most miner vendors are pushing the limits here. Up to 200W per PCI-E cable should be ok as long as the PSU and the cables are good quality and the connections are solid - most failures I've seen are caused by poor contact at the PCI-E socket on the miner or at the modular socket on the PSU.

Don't use 8-to-6 splitters, get a 2xMolex to 6-pin PCI-E instead and put that on two separate Molex cables.

Edit: As Biodom mentioned below, you should be ok with your stock cables

251 might be 251-256= -5degrees Celsius Grin

What do you expect when normal operating temps should be between 0 and 35 Celsius!

aah.. i guess i didn't read the specs. -5c degrees makes sense (it's cold right now)

Quote from: pekatete on February 02, 2015, 07:40:00 PM

If you are keeping the PSU's in the same enclosure (and hopefully giving them a decent load), make sure they just circulate the air rather than vent it, that may sort your problem. I think your PSU's fail before the the rigs shutdown.

no. the psu's don't fail, the system was set up to GET THAT HEAT OUT, not recirculate it. Its gotten so cold that i guess i broke the bottom limit.. NEVER expected that.

I replaced the fan with below and added a 2nd (push / pull) in the rear. Cools fine and a lot quieter than stock fan configuration. Fan comes with extra long connector for 3 or 4 prong. Plugs right up and reads and controls as 2nd. fan.

>snip images<

cool. I thought that silverstone 140 mmm does not fit and needs to be cut. Did it fit well without any cutting of shroud both in front and back?

No cutting or trimming needed, just plug patch cable in first then put fan on. It is close fit but works fine without trimming. Back no problem at all.
