Recently received these alerts from Malware Bytes while Electrum was running... any ideas?

I did a quick quote on coinwarz:

SHA-256 Bitmain S9
13000 ghz (13Thz)
1350 watts
15c per kw

vs

SCRYPT Bitmain L3+
504000 kHz (504Mhz)
800 watts
15c per kw

The results are pretty interesting... based on the prices we're paying here in Australia for power (it's actually .20c per hour taking into account that the calculator is in US dollars)

Scrypt blows SHA256 out of the water... the top 29 coins are all scrypt! BTC comes in at rank 30. Yes I know that this will likely change as the global hashrate and difficulty increases, but on paper it looks like mining scrypt may be fare more profitable.

Have I made an incorrect calculation?

1) Does the L3+ mine coins other than LiteCoin? A generic scrypt miner?

2) If I have a 10mhz miner atm mining at the moment, returning about 0.0005btc per day, an L3+ at over 500Mhz should theoretically do 50 times that? 0.025btc per day? (assuming the status quo)

Thanks

Is this config suitable to ether as well? I thought the blades could only do scrypt.

Sorry, I haven't been back to this post for a while!

I actually got those heatsinks from Jaycar Electronics here in Melbourne. They were just the right size. Had to drill the holes myself of course, but easy to mark them out and with the drill press.

Post us the cgminer configuration so we can see!

Just thought I'd drop in my 20 cents worth as well.

I didn't have much luck getting cgminer to work, but I'm running 2 blades (4 boards) quite successfully using BFGMiner 5.4.1 with the following config:

bfgminer.exe --scrypt -o stratum+tcp://scrypt.usa.nicehash.com:3333/#xnsub  -u username -p d=2048 -d gridseed -S gridseed:all --set-device gridseed:clock=775,chips=40

I've just knocked down the clock speed to 775 so as to not overheat them, so it runs comfortably around 10-12mhz, with .5% error rate over a week say.

Update...

I was able to finally get through to Martin, looks emails not getting through from the ISP I think, possibly blocked.

iSpace has a policy that unclaimed coins are donated to the pool after weeks... as I wasn't reaching the minimum threshold, the balance was being donated to the pool!

Apparently he's adjusting the minimum payout threshold to prevent this happening again.

Hookers and beer could be option? Anyone know a progressive establishment?

Bitcoin to the moon!

Has anyone else had any issues or lack of response dealing with ispace.co.uk?

I have tried to contact them several times over the last few weeks regarding missing BTC and I have had zilch response.

I was using ispace to mine a variety of altcoins and then shift them to Cryptsy for conversion. But since the issues with Crypsty, I deleted all the payout address for all the alt coins but left the payout address for my BTC wallet, and enabled their full automated conversion to convert to BTC. Once they balance hits the minimum threshold it should hit my wallet.

However, when I view the payouts page, the BTC address and balance are completely missing, ie. they don't even appear in the balances section.

This isn't the first time that this has occurred, it went missing before too. That's when I first tried to contact them but no response.

Yesterday there was a small balance of 0.004 with a bunch of pending conversions, today as I mentioned, they whole entry is missing... no balance, no payout address etc

Has anyone else experienced this problem or can advise of alternative way of contacting them except for their email address which is pools@ispace.co.uk ?

Thanks

OMG!
My payout finally arrived today! The .03897 BTC I tried withdrawing a few months ago finally hit my wallet today.

After many excuses and delays, well what can I say. Even though it did arrive, I more than likely wont be using them again.

Thanks for the Satoshi, but you guys haven't earned my trust yet.

Are there servers down again? Website not loading or mining

Waiting for withdrawal

C'mon guys.. .waiting for a 0.3 withdrawal for nearly a month now... it's been approved and still pending.

"Dear Customer,

Thank you for your email.

We are aware that the bitcoin sent to your address has not yet arrived. Unfortunately we experienced a network error that resulted in -1 confirmations.

It was rejected by the blockchain, but the bitcoin were taken from the wallet. Our developers are testing a fix for that right now.

It should be completed soon.

Please do not worry, it will be resolved very soon.

Regards,

Julie"

I like their definition of soon :-)

Update!

Yay! I finally got the blades to work... guess I won't be hassling eBay for a refund.

Incase anyone else gets into the same trouble, download the BFGMiner 3.00 from:
http://cryptomining-blog.com/tag/gridseed-bfgminer/

The correct parameters for BFG miner to detect the blades is:

bfgminer.exe --scrypt -o u -p -d gridseed -S gridseed:all --set-device gridseed:clock=600

You can also tinker with the clock setting from 600 up to 850, but I found that 850 resulted in more HW errors, but I'll play with it some more till I find a good speed without frying the cards.

Also, on a sidenote, if anyone's interested... I have a handy tool for backing up your wallet dat files. No scams, sourcecode is included.

Thanks for that. I actually have 4 boards.

I know that they should have come in a metal box, but the eBay seller is being abit dodgey. The images they showed on the ad clearly show the box, but they only shipped me the cards. I'm abit peeved off about that, as the product doesn't match the images.

The frame that I built should be sufficient for now, but I'm going to hassle eBay and get a refund if I can't get these to work. I can't verify that the cards actually work atm.

I've downloaded the STM drivers from the following site and reinstalled:
http://www.st.com/web/en/catalog/tools/PF257938

What should the devices appear as in the device manager?

Also, can you please post me a copy of your config file for BFGminer? (you can mask out the username/password of course!)

No advice? Surely someone must be able to steer me in the right direction
 

Hi guys,
I just purchased a couple of Gridseed boards from eBay and I'm having quite some trouble getting these set up and hoping you guys can help. I've used GPU's (Radeons) and Antminers (S1, S2, S3, S5's) in the past without any problems.

I've got a Corsair RM750 PSU to power these up.

I've made a frame and mounted a couple of fans on either end, and attached a chunky heatsink directly to the back of the Gridseed with some Deepcool Z5 compound.

The markings on the Gridseed show D25359H.

When I connect the power supply to the card, nothing happens. There is 12v at the tip of the power cable so it should be getting power. The fan does not spin.

When I connect the board to the USB port on my computer, I get a slow red flashing LED and an Unknown Device appearing in the Device Manager (Windows 7 Pro x64).

I've downloaded a couple of different drivers, but no luck. STW-STM32102 and CDM 2.08.30 WHQL Certified.

I've also installed ZADIG 2.1.2 and it does recognize something. It changes the Unknown Device to Unknown Device #1 and places it in the Universal Serial Bus Devices category.

I've also tried a couple of cgminer and sgminer suggestions I've found as well.

Can someone please provide me with a clearer step-by-step guide to set these up? eg. Download links for the correct drivers and cgminer configuration? I've got no idea what I'm doing incorrectly.

Any help would be greatly appreciated.

Hi,
I just got a couple of black blades (D25359H).

They arrived as just the board with no heatsink blocks.

Can these be run without a heatsink attached?

I suspect that it would be dangerous to do so for a prolonged time without one, so if I get a large heatsink block, do I attached it the rear side of the board without the chips, using heatsink compound and some tight screws directly onto the board?

Thanks

It was working fine earlier this year, I bought/exchanged about $1000 worth, and left a few satoshi's in there to exchange later when the price had risen. I should have pulled out sooner.

I'll contact support again, but I'm not holding my breath.
