With regard to overclocking: I noticed that in the /home/pi/Garden directory there's a familiar looking "miner.php" file.

So, I copied that over to /var/www/ and chmod'd it 755 and what do you know: your.miner.ip/miner.php serves up the familiar no-frills cgminer web display. This is nice as you can do instant pool switching and also monitor the hardware error rate. I was getting 8% at 310clock with 623GH/s over a 24 hour period - I'm testing 320 now.

It's worth noting that ducking down to 310 I didn't see a real aggregate change in the poolside hashrate so I'm thinking any additional speed is eaten up by errors. Nonetheless, these additional stats will help me maybe tweak some more of the command line parameters.

6.21% here @ 310 stock clocks. I would OC but my input temp is too warm. Does anyone know how to monitor temps? Is there really no temp sensors on these things?

at 350mhz this unit is hashing at 700GH/sec!

power consumption at XFX 850 Core Bronze+ (not modular, cheap one)

only 780W

nice

Damn, 1.111w/gh not bad.
What's the poolside hashrate like? I'm worried about the error rate of these chips, especially since there's not an easy way to see it.

Also how's the heat output of the unit? Heat sinks still staying reasonable?

I'm also curious to know how he managed such extreme OC. (Maybe ignoring HW errors?)

I tried 330mhz but HW errors brought the hashrate down to ~280ghs. 320mhz seems to be the sweet spot for my machine giving me an additional 5-10gh without additional HW errors. (only tested 310,320,330).

Just for the info, thanks the btcgarden fake invoice, that I asked them for, I paid only 8€ customs fee (from 700$ was 50$ invoice Wink

Thanks for the recommendation, I don't want to toast my nice new btcgarden so I'll probably be buying a nice corsair

Hi I think one of the best PSU for a set of 4 is :
CORSAIR CS750M 80+ Gold
The CORSAIR CX750M can also do the job but for 24/7 et nobody at home I want no risk so I have bought the Gold 89€ (120$ ?)
Silence, allways cold.

Correct, I'm using the four pin plugs and the +/- between the 6 pin and 4 pin plugs is reversed!! thats how I did it.

Also for the record, as I'm using 4 pin plugs on my btcgarden I can confirm that two wires carrying the current seems to be ok... so long as they are 16awg or better.

Also, I'm using two £20 LED 400w power supplies that I found on ebay... here are the ones I use. They read 12.25v with no load and amazingly 12.25v when the miner is running!!!! great value!

HTH

I would strongly recommend not using these. They are really terrible PSU's and will likely fail on you in short time. Hopefully they won't take out your miners with them...

Really? they're that bad? I was only trying the kit out on these but now you've got me wondering. Is it likely the voltage will shoot up above 12v if they fail?

they are not designed for 24/7 load, and are not very efficient - probably only 70% efficiency or so at full load. By comparison spending $150 more on a 80+ gold or better PSU would probably pay off in power savings within a few months

Hi, I got my miners Yesterday. F..K DHL they play football with one miner and the package seems ok but when I have open it one steel panel was twisted. The card had a shock, I think, I shall look this evening more exactly. I disconnected it because it badly put on the set.
I don't know for other countrys but in France I lost my time to set up correctly.
I have 2 lines for the web Free and Numéricable but it doesn't work.
I finally find the solution you cannot use the router for the DNS you must use the DNS of you Internet Service Provider.

The miner run Grin

Remenber only 3 blades Undecided

but good results.

Guys how do you can talk to the Rpi it ask for a login password ? how do you find it ?

BtcGarden I know that'is not your fault. I'll put a photography of the miner tonight.
I will buy 2 set of 4 blades soon Grin

Thats good to hear btc garden.

Regarding PSU efficiency. I was looking and 90+ PSUs were £100 !! I suppose they are cheaper if you plan to keep upgrading your mining kit over the next few years and use the same PSU each time.... however think about it, the miners you buy today will probably be good for nothing in 4-6 months time and I'm only "playing" at this for now so I choose to buy £20 PSUs, save myself £160.... if I keep mining then that saving will be spent on extra power fair enough.... if I find myself buying new kit down the road I'll invest in efficient PSUs.

I placed my first order with BTC Garden 2 days ago.

Is it normal to still see no updates on my account for payment and shipping 2 days later? Huh

I hope to place another order this week. Cool

Thanks

Rob

have you paid for your order ?
have you received email about order?

if not contact with customer service, ask about how much you should pay, pay and wait for shipment.

dont worry they are not scammers.

Got an email today from them letting me know shipping will happen in 2 days. I hope! Cool

I mean I've heard it takes over 30A to melt 16awg cable that's only a foot or so long. So theoretically these could run on one cable a piece but for the love of god nobody try that.

Also with regard to that PSU - 78% efficiency? That's got to be at least 120 extra watts you're pulling. Don't know what you pay for electricity but I've learned that a top-shelf PSU is key these days.

When I got the rig today I checked every step of wiring it, even used a multimeter... guess what? I wired two out the four power plugs BACKWARDS! Good news is the unit seems to be protected against this so once I corrected the problem all was OK!!!

I didn't pay attention when hooking one of mine up and somehow managed to plug in an EPS cable instead of PCIE. Luckily it did not damage the unit - no idea how i was able to do that since I thought PCIE plugs were keyed.
