We need grumpycoin to go to different exchanges!!!! Mintpal would be good but we need more like bter etc, the chinese have to buy this coin like crazy!

Welcome!

Agreed - Only problem is from what I've read you need mega BTC volume to get onto BTER.

For now not. We are working first on design, later on when design will be ready we are going to make some changes. Also we will try to give you changelog at downlaod page: http://www.grumpyco.in/wallets/

Ok. Design is interesting, i personally grow tired of absolutely identical wallets for most coins.

p.s. I think that you need to start a new thread, as you can't change first post and people cant see all new changes new community is making.

I am working on a new ANN thread now Smiley

Yeah well done Clarv. I could tell you where getting stressed, and now you can get back to designing images!

I've had a thought.

Why haven't we tried getting on:

https://www.swisscex.com/market

I've emailed both but no response, can you lot do the same and show some suuport?
385  Bitcoin / Hardware / Re: Server Power Supply Interface Board - for standalone miners and GPU rigs on: March 12, 2014, 03:54:14 AM
Would you be able to? I think that questions your capabilities as a hardware assembler and I can't answer that for you.
But anyways... If the risers only take in 12V from the molex, and the cards you mentioned pull the power you mentioned combined through the 6/8-pin and risers, then yes the DPS-1520 should be able to power your 4 GPUs and their attached risers. Your ATX would then only need to source power for the other GPU/riser (~300W?) and motherboard (~200W?) so a 500/600 ought be sufficient. Probably?

I'd rather run wires for each connector instead of sharing. It can be wired with two connectors sharing the same wire, but its reliability depends on the length and gauge of the home run because you'll be pulling the full current of both connectors through it. The more current through a wire, the more power dissipation in the wire. That means the wire warms up and, if it's way under spec, could melt or burn something. Power dissipation in the wire is also a result of voltage drop in the wire, which means less voltage getting to the load, which means a higher current required to power the load fully, which further increases the strain on your wires. If it's calculated out properly you shouldn't have any problems, but in general the more copper the better (at least as far as is practical with weight/price, like for most of what you're doing 000AWG won't do you any better than, say, 14AWG).

Yes I am more than capable of putting it all together, but thanks for picking apart my question when the intention was plain to see :p

No, seriously, you've answered everything I need to know. I will get some Molex connectors tomorrow and put it all together.

And for the record I'm using 16awg wire, direct from China! Haha. Although it looks suspiciously thin for my liking, and I'd guess its actually 18awg. Either way I'll wire up the connectors separately to be on the safe side.

Thanks again for your time.

Tony.

When we receive the information from Cryptorush we will ensure we ask the proper questions i.e. account id and amount they will have to match in order for us to initiate a refund.

By the way thank you for the first donation we hope to see more to help he ones that lost.



Hate to bring this up again, but still no sign of the 50k as promised. I was one of the first to Like your facebook page, and also to follow and retweet.

I have DM'd you on Twitter but no reply too.

Also, how much power is drawn through the powered risers?

 Smiley

Powered risers molex draw max of 75 watt which is the same as if you use 16x PCI-e riser without molex.

Thank you.

Do the powered risers have to come from the same 12v rail as the motherboard?
388  Bitcoin / Hardware / Re: Server Power Supply Interface Board - for standalone miners and GPU rigs on: March 12, 2014, 02:38:48 AM
Depending on the strength of your desktop supply, it should. Powered risers you should allow at least 75W of 12V per riser, and at least 300W of 12V for your other GPU. Depending on your board/CPU, you'll want 100-200W for that. Looking at getting at least 800W desktop supply to run all that.

If anyone, ever, anyone at all, has any actual experience building GPU rigs with riser cards, feel free to chime in. The most I've done is 3 GPUs direct on a board, with an ATX giving 35A of 12V and a 500W server supply doing the rest. The only advice I can give regarding high-end crap is somewhere between theory and conjecture. Never used risers, never used an ATX supply over 500W, never used more than 3 GPUs, never used a DPS-1520.

Still a damn site better than knowing nothing - Thanks buddy Grin

Two more questions while I've got your attention, if you don't mind?

-Would I be able to wire up MOLEX connectors aswell as the PCIE to the DPS-1520 to power the four cards/risers. And then use say a 500-600w PSU for the other card/riser/mobo?

-Is it wise to run two lengths of both live/earth from PSU to each 6 pin connector per card, or can it be wired so that the second 6 pin is jumped off the first?

Like this -
389  Bitcoin / Hardware / Re: Server Power Supply Interface Board - for standalone miners and GPU rigs on: March 12, 2014, 02:14:00 AM
Preemptive disclaimer that I don't work with GPUs a lot.

But I would imagine the 300W and 280W from your cards, part of that is coming from the risers. If you don't plug the risers into a heavy external supply but run them off your ATX, I'd allot at least 6A of 12V per riser. If the 300W/280W is straight external, they should all run off the DPS-1520 without issue. If that includes the socket power (from risers in this case), you could power the risers off the DPS-1520 and still only be at 80% capacity.

If, then, you ran your 6950 and motherboard off the ATX supply, I'd recommend probably at least a 500W unit. Maybe more depending on what processor/motherboard you're running, and what overhead you want to allow for.

What you could do, and an idea I've toyed around with but haven't tested yet, is actually get two server supplies in parallel load-balanced (I don't know enough about that particular model to know if they current-share or not, but I think most do) and get a picoPSU running off the 12V bus for your motherboard. Those things aren't terribly expensive, and run around 96% efficient. If you isolate your riser power from the motherboard power (either by using the recommended USB-style risers or cutting the 12V lines to the ribbon) you shouldn't overload anything on the picoPSU by trying to pull GPU current through it, and anything else requiring 12V (like GPU, or processor VRMs) would pull straight from your ~3KW 12V source.

Right, I've somewhat conflicting info from elsewhere now.

Simplified - I have DPS-1520 wired to 4x GPU's. Can my Desktop PSU power the MOBO and the powered risers too (plus an extra card if I have the headroom) ?

Keeping coins on exchanges is stupid and ppl can blame only themselves if they loose something. It is your own risk sending coins there. Don't snivel like 13yr old schoolgirls. Accept your mistakes. Same with Cryptsy, Kraken or all other.

Its the fact that trust has been lost yet again. Why shouldn't we be able to keep coins in an exchange. I assume Day traders must have to.

Fuck me, has this really happened?

I am so glad I got a window of opportunity to withdraw my coins about a week ago, and can only feel sorry for those of you that didn't.

What really annoys me is that I really liked Coinmarket, and although there was quite a bit of downtime, they kept us updated on the status of the problem.

I wonder (if the owner stays alive  Lips sealed) would this stand up in court because the warning about it being Beta was up and to use at your own risk?

Grumpycoin has a new windows wallet!

First version developed by Clarv with help from our Grumpycoin community.
Details and download links coming up.

Fixing github and website first.

Check out the idea of BatCoin guys:
https://bitcointalk.org/index.php?topic=400753.msg5639469#msg5639469

I kinda like it but on the other hand I still think it is very expensive to spend 7 BTC on adding the coin to Cryptsy.

But if it works, then why not.

Hmmm, Food for thought!
394  Bitcoin / Hardware / Re: Server Power Supply Interface Board - for standalone miners and GPU rigs on: March 11, 2014, 09:41:59 PM
Oh, and regarding your initial question "Is the DPS-1520AB 1440w?" I've gotten used to dealin with people with horrible grammar, and people asking about different models, so that I misread it. A quick glance at the Internet tells me it is a 1440W supply. If a single GPU doesn't pull more than 360W then technically you'd be within range of the supply with 4 GPUs; for longevity I'd try not to pull more than 325W (90% load). PCIe standard doesn't really allow for more than 300, but not all high-end cards are standards-compliant with regard to power usage especially when overclocked.

Admittedly, I didn't word my question very well, and even my edit isn't much better!  Roll Eyes

Can I pick your brains while ive got your attention?

I have:

2x 280x VaporX's (300w each?)
2x VTX 6950's (280w each)
- These will be running off the DELL 1520ab.

I will have one more 6950 and 5 powered risers and motherboard running off another PSU.

Can you suggest what wattage PSU I would need to power the MOBO/RISERS/6950?

Thanks again.

395  Bitcoin / Hardware / Re: Server Power Supply Interface Board - for standalone miners and GPU rigs on: March 11, 2014, 01:56:22 PM
Seems like it wouldn't be necessary. I don't think anything cares much which 12V rail, as long as there's a common ground. I haven't used any risers but others have been strapping them to home-rigged server supplies without any problems... I think. Someone'll surely mention it. Odds are it's been talked about sometime in the thread so far though.

PCIe standard allows 75W through the socket, 75W through a 6-pin and 150W through an 8-pin. So the riser, taking over for the socket, should top out at 75W, or at 12V 6.3A

Thanks for your help. I've read through the thread a few times and didn't see anything. I've got my head around this now, so time to get it all put together!

What I meant was -

Do the Molex Powered Risers need to come from same 12v rail as the motherboard?

And also, how much power is drawn through the powered risers, do you know?

yeah keep posting people with hats on! there's plenty on the web, won't change the fact that this coin is dead.

Well worded and backed up by facts to support your point.

Just the type of post I love reading.

As above really.

Have a Dell 1440w server PSU nearly ready to go, but need to know if I need to use the 'MOBO' PSU to power the risers?

Thanks

If anybody ever turns a profit on this coin they better thank Mk2vr6 and placebo. These guys have been relentlessly bumping this thread day after day, week after week. Rarely anything important to say but they never gave up. The effort is seriously commendable I'll bet Mk2vr6 is in this thread for 14 hours every day and any excuse at all to post he posts. If it wasn't for these guys this coin would have been dead a week after it was released buried in the abyss of junk coins. It may go down as the crappiest coin in history to end up being profitable so people owe these guys some beers or something. At this point I will literally be bummed out if these 2 guys don't get something out of this. If there was a bitcointalk award for effort I would nominate Mk2vr6. If I was a coin developer I would become this guy's best friend!

Thank you for your kind words. Really appreciate someone taking the effort to realise how we have all been keeping this alive, not just myself!  Cool

Don't forget KRO55, and CLARV for his amazing artwork too. There are a couple others I dont know if they want to be names that are active on the IRC that have been helping, and as this is now a community run coin, we urge everyone to get involved!

If you've got some ideas, or just want a chat come and join us on the IRC channel.

We have a few neat little tricks up our sleeve we are working on at the moment, so I again ask you all to keep an eye on this thread  Grin
