Topic: GridSeed 5-chip USB miner voltage mod - page 11. (Read 157001 times)

The large ASICs can mine multipools too, or any Scrypt altcoins, so I don't think that small scrypt rigs are somehow immune to the arms race. You'll see more and more new coins use other algos, this is already happening. To me it looks like the only chance to ROI is upgrading to the next ASIC while you can still sell the old one, which is what I'm trying to do. Got so far as Gridseeds (5-chip) -> blades -> Zeus (backorder unfortunately, I hate those).

Yeah thats cool for such hashrates on gridseeds! Im running 19 basic ones for 7.1 M/hash  and 150W in total.
Getting a replacement (had a DOA) and 4 more next week to bring it up to about 8.8M/hash with an expected 180-185W.

You might want to underclock them again if profitability reduces to much but atm your setup is great!

Approximately 560W total .... not bad, eh?

$20.00 bounty to anyone who can make me a pre-loaded SD card with Sandor's latest autotune for Rasp Pi that is working, and give me an hour of their time on teamviewer this weekend to make it work.


I am in Toronto.

I get that, but what I think people must consider is that difficulty increase with LTC is not the deathknell to 10M scrypt rigs that everyone might think, as these rigs can still be profitable as proxies for LTC through alts. In other words, you can bank on at least one or two or three alts having awesome profitability--and almost all of them are scrypt--as time goes on, and you just stay on the profit pools like waffle and clever while your colleagues continue the asic arms race on LTC that will certainly ensue.

Or am I totally off?

nst6563 - I ordered a Fury when it had everything included too!  I wasn't planning on buying anything but I couldn't pass that up.  Zeus Blizzard should have 6 chips now (yesterday's update) so potentially 1.5 Mh/s so I really hope that is what a Fury ends up being.  Fingers crossed.

Sorry... I'm using sandor's cpuminer fork with the autotuning features.

He actually made two calculations, one straight LTC and one where the diff would have very low increase to simulate higher income from multipool for example. But alot did still not make any ROI

thanks, but what program to run the seeds?

sad, but true. The thing is, though, and correct me if I'm wrong, these ROIs are based on litecoin, correct? I plan to multipool these gridseeds to death.

I just have them hooked up to my win 8.1 pc. 

Considering it came with around $60 worth of accessories that I didn't have but wanted anyway....I didn't consider it too bad.

I (and apparently others as well) had seen no mention of 14mhs units for anywhere near that price either.  The closest I saw was 13mhs for 1800 or so.

No I'm not talking about price decrease of A2

there are so many companies that will deliver asic miners soon.

Fibonacci is coming out with a miner that will give ( at this point 14Mh ) for 350$ not yet updates on their website but it is 14Mh and this number could get higher to match competition.

Flower tech ( funny they make a gridseed looking one as well )

and I suggest everyone to look at this chart https://docs.google.com/spreadsheets/d/1msn9gC7wgBYdiyOLZLhQifOSKpt3ukdnuTy14m-F-s8/htmlview?usp=sharing&sle=true

somehow today the days to ROI collum does not work, but many, especially gridseeds will never roi

what controller are you using?

so the silver ones are less stable overclockable?

Hold on, which companies and when?

This must be a reference to the Titan. I hope I'm not wrong, but I don't think we will see Titan until September.

Unless you're just talking about the natural price decrease of the A2 chip over the next few months.

The hardware hack itself is flawless; the problem is I have no time to change from hashra controla (which seems to be the problem I guess--though I have a crazy reject rate reported when I run above 600khz), and last time I tried to get a pi to boot on my own with wheezy, I had zero luck and lost precious sleep for the following work week. So here I am with zero time to change image on pi (if that is even the problem...) and I am at less hashes and paid out to my modder $200.00. So I am set back two weeks at least in profits at this point and losing ground fast.

I have lost so much money in mining....I wanted to stay ahead somehow by getting an A2, but realized I can't even really afford a blade at this point, so I thought, "hey, I can get 2.5M for $200.00? OK, that's what I can afford to do at the moment....let's go for that with a volt mod".

I am using clevermining, but I'm not married to it. I don't think the problem is the volt mod at all; the problem is either controller or pool.

I don't quite understand, however, if it is the controller--ie that you need to tune out the gridseeds with specific khz--as other users in this thread are running all of their units at 1150, 1200, etc.

I ran mine at 1200khz for 12 hours and I have a few HW errors, but the reject rate showing on controlla is crazy! Like 20%. Reject showing poolside is substantially less though: like 7%. But overall hashes poolside are about half of what they should be....

That's pretty expensive knowing other company's will have +10MH for around 350$

Some are using 49.9k, some are 50k.  Some gridseeds have trim pots on them, others have 2x100k resistors in parallel to equal the 50k.  I just used what I had on hand since I had a surplus of trim pots and 100k resistors  

I've only got 6 gridseeds but they're running along nicely at 3MH/s.  I put in a pre-order for one of the GAWMiners 1MH/s Fury units that came with just about everything including the kitchen sink for $199.  It was a deal I couldn't pass up since it came with the miner, all power cables, network cable, raspberry pi, pre-loaded sd card, and free shipping.  

Hey Wolf, what is the power usage of those 26 OC miners? just wondering if its still worth OC'ing with the upcoming nextgen ASIC's.
