By stake an address, I presume you mean save an email address?

Unfortunately can't do this as it requires the password to save.

To be honest, I thought this account was lost until I randomly opened this site on my phone.

If you see my history, I posted images of a miner.

I was thinking I could post these again but include my forum name or message...

[Help] Change Email / Password

I currently have access to my account (this one) on my phone, however when I set it up last year I used a fake email address.

I have since forgotten my login password and obviously cannot make any profile changes as a result.

If I logout from this phone, I will forever lose access to my account.

Can anyone/mods help?

I am willing to prove I'm the original owner if necessary.

Re: Antminer S5 + 3D printied mods

Hello Vorta and others.

I am wondering, do you recommend the mini heatsink on the exterior side? Do they actually increase thermal dissipation (by themselves)? I might want to add some if there is a difference on temps and properly balance the temp on the outer chips.

Are these too big? http://www.ebay.ca/itm/100pcs-Aluminum-8-8x8-8x5MM-Heat-Sink-for-StepStick-A4988-Chip-IC-LED-Power-IC-/171857107604?pt=LH_DefaultDomain_0&hash=item28037b5a94

Any recommendation on thermal glue?
I've been informed directly by Bitmain that the external heatsinks have basically little or no effect on cooling, which is why the only shipped a few miners with these mini heatsinks.

Probably a waste of time/money IMO.

Thanks very much for your response - I thought for a while you were managing to keep your 400Mhz miners under 60°C in a warm ambient environment!  Grin

Running @ 350Mhz in a warm environment I'm getting temperatures of about 68/72°C. HW errors = 0.0012% which I think is pretty acceptable judging from your response. I would like to overclock to 380/390 however my only concern is whether or not running the miner at these temperatures, and higher, will affect the miner's lifetime..  Huh

Keeping HW errors low is a good sign that it's running well, but surely 70+°C couldn't be too good for it...I'm not sure..

Edit - I will send you a small tip when I get home, really appreciate the models!  Wink

I updated all my 6 S5's and theres is not an issue about it. They run smoothly and the load has decreased.
Good to hear. Can you elaborate on what you mean by decreased load? Thanks

Fit it just like the mod is, linearly aligned with the fan ducts aka on top of the heat-sinks.  The idea of the mod is to get most air through the heatsinks rather than escaping through the sides and top.
I am assuming here that it is a temporary fix as card-board can be a fire hazard IF the the dreaded S5 overheat bug hits you.

Ok - so I've fit it pretty well I have to say. On top, its going from the very front, under the cpu/mobo, then all the way to the end. The bottom is similarly covered to the mod, without the bulge obviously.

Temps are 64° / 60°, so unfortunately it doesn't seem to have helped.

I live in a very hot country and during the day there's no A/C so room temp will be pretty warm, not sure if I'm comfortable leaving it running if I'm getting these temps in an AC'd room  Sad

Maybe I could manage it remotely and underclock if it gets too hot?

There, ma friend, lies the root to the rise in temps ..... try using simple card-board over the top and bottom (while you sort out the 3D printing) and you will see a drop in temps.
Should the cardboard on top sit just above the heatsink and not extend across to the sides? Or should I try to sit it on top of the PCB board, extending to the side panels?

Thanks

Printed off the 2 ducts and have them mounted with 2x Ultra Kaze's. Here's a comparison:

Old setup
Kaze Pull + Stock push + no ducts = ~53°

New setup
Kaze Pull + Kaze push + 2 ducts = 63° / 59° (there's a few degrees difference between both boards strangely..)

Are the above temps expected with my new setup? I was expecting a bit cooler, especially in this air conditioned environment.

It's possibly worth noting I don't have top or bottom plates due to printing difficulties.

Edit: temps have risen to 65° / 61° now  Sad

No you will want to go trade it in for one with 4 pcie cables. You seem to be sticking with Corsair brand.  If you are really wanting that brand I suggest the RM1000.  You will have zero issues using it.

When your looking at pci-e cables they most likely will list each plug.   So if you sort by ones with 4, you are going to get a lot of PSU's with 4 plugs but being powered by 2 cables.
I returned the PSU and got the GX1050 instead, for the same price. The Cougar has 4 separate cables and the S5 is whizzing away as I type this  Grin

It's running at 49 degress on stock, but I'm going to change it and add 2 Corsair SP120's I also bought...Will be interesting to see how much quieter it is, but also how much hotter it will be without stock.

Now I just need to figure out what all those numbers mean on the S5 dashboard!

Edit - I noticed for the past 5 or so minutes it's actually been mining at around 1300 GH/S. Thought it was odd considering it's running stock..

I'm currently pointing to - stratum+tcp://stratum.antpool.com:3333

This doesn't mean I'm solo mining right? This is pooled mining and I have to pay 1% fee or something...

Should I also include stratum+tcp://stratum.antpool.com:25 + :443 ?

What if I pointed to solo.antpool.com instead? Would that be solo mining?

I have just received an S5. I know absolutely nothing about the different types of mining pools, and after some researching it looks like it would take a lot of time to fully understand them all.

On that note, what pool can you recommend to an average Joe with an S5?

Ok, say I ended up getting a CSM750, not the CX750.
It's an improved semi-modular, Gold-rated version of the CX750 - http://www.corsair.com/en/cs-series-modular-cs750m-750-watt-80-plus-gold-certified-psu

I thought it would have 4 separate PCIe cables but there are in fact only 2 cables, with 2 PCIe plugs on both.... Angry

Should I 100% get a refund and buy something else, or will the above be ok?
I'm at the stage now where I just want to get it powered and running.

It has arrived  Grin Grin Grin Grin  Unfortunately doesn't have the mini heatsinks that some other user got :-(

The side panels are fine to leave them the way they are right?

I've had this one as well, and you're correct.  It's two cables with two PCIe connections per cable.
Ok, I presume given that it'll be powering a miner 24/7 it would be advised to have dedicated cables for each PCIe connection...

And my seach continues  Cheesy

It would likely work, but there are better PSUs out there for what you're doing.  Such as the ones in my signature lol Tongue
I would consider one of yours if it wasn't for the fact that you're on the complete opposite side of the world to me  Tongue

Also remember that the Corsair CX750 only has 2 x pci-e plugs and the S5 needs 4.

In all honesty you're better off going for a branded psu with minimum 4 pci-e connections or a server supply with the same.

If you're thinking about getting another S5 in the future then the EVGA Supernova 1300 or 1600 look just about perfect for the job as philipma1957 mentioned a few posts back as they both have 8 pci-e connectors.
I've seen other people mention this here that the CX750 only has 2 pci-e plugs, this is wrong. As per Corsair's site it has 4 plugs - http://www.corsair.com/en/cx-series-cx750m-modular-atx-power-supply-750-watt-80-plus-bronze-certified-modular-psu

I also don't like using Dogie's guide. Reason being he gives his rating but doesn't state why for example EVGA Supernova 1300W gets 93.0 rating, while the exact same model in 1100W version gets 78.0 or something similar  Huh Huh.....No explanation and it doesn't make sense. Also, he states the CX750 has 2 connectors, which is probably why people don't realise it has 4.

One last comment, what constitutes a no-name PSU? Corsair/Thermaltake/Cougar/CoolerMaster/EVGA/Gigabyte , is it safe to say these aren't no-names?

Try not to get no-name PSU's, as they can fry basically anything.
I totally agree, but does Cougar really classify as a no-name? That's the question...
Also it is Gold certified so that helps.
