1  Alternate cryptocurrencies / Mining (Altcoins) / Re: GridSeed 5-chip USB miner voltage mod on: March 28, 2014, 07:04:07 PM
so anyone tried swopping out the oscillator crystal (x6 tink its marked no?) for a higher frequency one?

alos whats wiht the reistor values, i mean where did the 39k reisitor value come from? could it be higher?Huh (in line wiht chip u9 upo1111)

and laslty has anyone got or know where to get hold of the data sheet for the 2-bit VID buck converter chip u2, (up1509)

and for ref r211 is labeled a 3.65k -1% 04 and R212 10k 1% 04

And final why do the solder bridge to short out vid0 and vid1 ? then replace the matching reistor. Why not just replace the corresponding resistor to vid0 open and vid1 open? which i believe would be R139 default value set at about 22k. )

or did i miss something.

i try but i dont have the values and compents sizes -at the moment - to try.

Are you an electronics engineer? I'm interested in any hack that works well and is the easiest one to do.
I found one other shortcut that negates the need for the pencil mod part. I'm still testing its results.
So far, 135% to 150% stable gain in overall hash rate has been achieved at 1000MHz.
1100MHz throws less red nonce HW errors but it's still too much.
1200MHz stable is still pretty much impossible at this time with current mods.
PM me if you'd like to correspond and we can figure something else out together.

thanks ill take that as compliement - electronics engineer - but no. i did study appplied physics wiht computer over 12 years ago. didnt really get into it as a carreer started travelling instead. now ive forgot more than i know. still know the basics and beyond and dabble in it as a hobby - heck been into the electronics and computer since a kid wiht my dad. assembled a circuit at 5 and wrote a compuiter program on spectrum 48k at 7. ahh back in the days. problem i now have is though that i live in finland and dont know where tyo get most of the stuff from - language also an issue - so i result to online purcahses most of time which takes time to delivery. heck if i had the parts the crystal would be swopped out now along wiht the reistors. heck im itching to use my new rework station. oh and have things moved forward so much in 12 years. so im a bit behind. but i catch up well - just wiht coding you know the basics you can pick it up and understand it. so anyone know a good site where i good hunt for the datasheets for the chips?

Do you live in Helsinki or close by? In Helsinki (or you can just order online) there's at least this shop for electronics that I know of: http://www.partco.biz/verkkokauppa/index.php?language=en .

As soon as someone finds a way to replace the pencil mod with resistor or something (and/or when wolfey2014 reveals the new, better mod), I think I'll try to mod one of my gridseeds as well (and then the rest if I don't brick that one..Smiley

thanks ill chcek it out, especially postage - helsinki prices are pricey Smiley - not far from there about 1.5 hour on motorway. Id say youd nearby yourself? If youd like someone to mod them for you, ive got the kit, not the parts let me know.

Yeah, I live in Helsinki. I'll wait still a bit and see how this goes..  And thanks for the offer, I could see first if I can do it myself, and if not, I'm going to contact you then!:)

I just had to come to make a small update; i've had all the miners running now for about 10+ hours (3,6MH/s, 850mhz) without any problems or crashing with raspian wheezy & cgminer. So yeah, although it took time to get the miners, I really think to include raspberry pi instead of the controller is a brilliant idea!

They do make a lot of noise I think- now if only there was a way to adjust the fans programmatically..


You can probably put some resistors to downvolt the fans or just unplug them completely. That's what I'm planning on doing, my GPU fans are loud enough haha

That's what I actually ended up doing- I unplugged the fans and now i'm in process (as in the PSU in in my bag right now) of replacing the included loud PSUs (they're almost as loud as all the 10 units! And they make the room smell like something you're not supposed to be inhaling too much:) with a better, quiter and meant to be in a room you're living in -type.

Hashra is not a scam but they are more expensive than some of the group buys over on the bitcoin mining>hardware>group buys forum.

Concur - not a scam.. just a very (VERY) poorly run operation thus far.

I agree- yesterday finally got my units that I ordered on 24.2 and can also say they're not a scam BUT the company seems to be run by only one guy, and he has too much to do. The (too) long delivery time (almost a month) is too much, and on top of that, there's no communication/support on this forum from the company after 25.2, even though user "HASHRA" visits here almost every day if you look at the profile. The other user, StevenJ, who also claimed to be working for hashra hasn't visited the forum since creating and "filling" his profile , there's no updates on facebook and twitter is in some kind of auto-spam-SEO-mode, so I don't know, there are lot of these small uncomfortable strange things going on here.. but speaking of SEO, they've managed that well, since their site is top result on the important keywords..

It would really help if someone from the company would be here to provide support, answer questions about delays etc. Seems every other company even with fake products does that, so I can't understand how they're not.. The phone number on their website doesn't work either, and to reach Simon you have to send multiple emails and wait. Although when he does answer, the communication is professional and he does answer the questions, so as long as you can just wait few days, everything is basically ok, but since we're talking about $2000+ devices here, I would expect faster responses and more transparency.

Also I wasn't first sure what to say about the Raspberry pi.. I mean, I did order the controller, but on the same time I was thinking of buying raspi anyway.. But now when they're running (and they do work, which is a relief), I am happy I got raspi in the box (and hashra promised to send me the wiibox and their own software anyway, so no problems there..)- so yeah, I guess this was a right choice from them. As a bonus, the Rasberry Pi is red, not green.

Also I have to give them credit for the new support page and instructions.

So all in all, even though I got the miners - because of the delays (I did lose a lot of mining time==money because of all this), poor communication (nothing here on bitcointalk, days delay by email, no phone), and the strange feeling about fake posters and "ghost" profiles (if you read this thread you'll understand what I mean), random waiting stuff etc uncertainty (when I order stuff, I shouldn't feel so great relief after I got what I actually ordered and paid for), I can't really recommend them at this point. But I do sincerely hope they'll improve, for all I know it could be just a rough start and some bad decisions for a very new company..

I send a private message to both users "StevenJ" and "HASHRA" asking them to reply to this thread, hopefully we'll get some updates from either of them soon..

also, there's this thread: https://bitcointalk.org/index.php?topic=416672.40 where people are more or less on the same situation...

ok I take back what I wrote previously.. I googled a bit more about "Shipment information received" in DHLs system, and this simply means the seller (hashra) has sent them the waybill number, which is the one we've got in the mail. This DOES NOT mean the package is actually shipping anywhere, it's likely not even picked up yet..




Nice that your tracking number is showing in the DHL system, mine in not showing :-(

Yeah, but the sad thing is that that doesn't yet mean anything, I could have sent the number to them by myself, and it would show up there, since it just means they have the number, not the package.. So until it says "package picked up" with a time, there's really nothing to confirm yet about actual shipment..

just a quick update, my tracking number is found on dhl system now, it just says "Shipment information received", but after all this waiting I'm really happy things are moving..

I just realized that the problem why this waiting has/is been so long is that it takes a week between any kind of update: hashra received my payment 28.2, status changed to Awaiting Shipment on 5.3, and today finally on 12.3 I can see that there's a package in DHLs system.. During this time I've seen group buys that have been cheaper than this, and of course many people who ordered from asiabtc (& others) on the same time have already got theirs (and running these on rasperry Pi's, which wasn't either possible on 24.2), and for some reason at this time the mining profits on many scypt coins are down (just as example on 24.2 clevermining.com had 0.01 BTC/day per MH/s, currently it's 0.00651) , Mt. Gox went bankcrupt and Satoshi Nakamoto was found, until we found out he's Dorian Nakamoto, and actually not found.. I guess I'm just saying that 3 weeks+ really is a _long_ time to wait miners, something I didn't worry about too much when ordering Smiley

What I find interesting is that Hashra only has a handful of customers, they are with 4 FT members working at hashra, they have time to logon to this site (last logon 2 hours ago), they have time to read this thread, but they do not have time to do proper communication with their customers?

They are even too lazy to start their own thread in the Mining sub forum.

Something is not right here and I really hope all of you will get their miners but I am happy I didnt order with these amateurs.

Actually, status of my order also changed to "shipping" and I received the tracking code just after I had posted my last message here.. I was thinking it's a bit funny that the email went unanswered, but as soon as I post here, the product is all of a sudden shipping..Smiley

I asked them what "awaiting shipment" means. There only response was just as vague. It means its one step from being shipped. (kinda figured). However I got that status change Friday night (China time). And I got it delivered just today. I have a tracking # now. So I would assume that you to will probably get yours shipped soon enough.

I to will post here with pics and such once I get mine in the mail.

Can I ask if your tracking code is working already? Mine is not found yet from DHL:s site.. Propably it's not yet in the system or something, but I was just wondering...
11  Alternate cryptocurrencies / Service Discussion (Altcoins) / Re: hashra.com asic scrypt.... scam? on: March 10, 2014, 02:08:40 PM
Hmm.. I was told that estimated shipping date was on friday, but so far haven't heard anything. I also sent an email to ask about the tracking code today, but haven't heard back yet and the website still just says "awaiting shipment". Let's see how this goes, hopefully my units are shipping then today as well..
12  Alternate cryptocurrencies / Service Discussion (Altcoins) / Re: hashra.com asic scrypt.... scam? on: March 04, 2014, 02:16:07 PM
I'm in same boat, I ordered a week ago and emailed them asking when they'll be shipping but no reply yet...



If this is of any help, I ordered on 24.2 and received a confirmation that they'll ship my order between 6.3-13.3 - I asked about the one week delay between payment and shipment, but didn't yet receive any reply.. But they do state this on their website as well (that delivery time is from 3 to 14 days after payment (http://hashra.com/shipping/)).. I was also told they'll contact me when closer to the shipping date, so far haven't heard anything, but there's still time..

There's discussion (& screenshots) on LightningAsic -thread about their controller being able to be upgraded to hash at 500kh/s per unit in stead of the 300kh/s per unit. Can these be upgraded on similar way, or is it just the LightningAsics with custom firmware..?


I have a set of 10 of these from LightningASIC...do NOT rely on that.  Per my earlier post on this page, the firmware is janky and bug ridden.  Lots of folks (including myself) have to spend a fair amount of time babysitting these.  I'm willing to make a trade off on hashrate if it means I don't have to spend lots of time monitoring the devices as is the case with the LighteningASIC firmware.

That's also the reason I was asking Hashra a question about this...lets hope they do!  Because at the price they're offering these if its much more stable then it's totally worth buying these from them.  If its going to have the same issues as LightingASIC users have mentioned then I'll pass.  Make things worse, I was sleeping last night and heard a pop -- one of the PSUs blew out!  So now I'm out a PSU to power 5 of the 10 miners. Sad

thanks, and sorry to hear about the PSU! I just ordered mine (10pcs) from hashra, so let's see how this goes, I'll post here as soon as I get them and keep you updated how reliable they work.. I paid with bank transfer, so might have to wait for some time..

I've been following these gridseed asics since they were announced last month, and been a bit unsure where to order- I was going to go with asiabtc (especially after that firmware upgrade thing), but seems he has too much to do with the current orders so that and now these bugs made me change my mind (well and price in eur is a bit cheaper as well:)..

I'd like to reserve 10 of the 5-chip Gridseeds please.

There was doubt about the CE markings & shipping to Europe in the thread- I'm also based in Europe and was wondering if UPS/DHL would be safer delivery method then? seems it costs much more though compared to regular mail.. so would you think there is any possibility of getting those markings on these, or will there be CE markings on next batch?

And just one more question - is the software windows only, or are linux/os x supported as well?
