Hi All,

So I set up my Mercury miner on Tuesday night, managed to get it hashing at around 80 to 100 at midnight. As soon as .89 was released, my Mercury happily hashes at 102 on the pool. Today was a little odd, I witnesed on the pool side that my machine jumped from 50G to 150G then back to steadily hashing at 102G, very odd I thought?

I'm with Slush's pool and currently am sitting at 0.25505708 BTC since Tuesday night from my Mercury. I've roughly estimated it will take me 10 days to mine one coin if rounds are 2 hours each with a reward of .008 / .009 BTC.

Are you getting a higher hash rate from your Mercury? What settings are you running?
I've read heat helps some machines, I might try this when I get home...


Can we try and keep this thread specific to KNC Mercury machines?

Cheers,
jmevz

I'm pretty sure you mean 0.98 firmware.

Ordered and paid 2100usd total for my Mercury Aug. 8, got it Oct. 25, and it is one of those

with 1 underpowered vrm out of 4, so it is at 75%. Its on bin .98

I spent a few days trying everything short of pulling the
board apart to get the vrm working, all to no avail. The only
thing I noticed, was that bin .94 gave some crazy unstable speeds and burned hot.
It is true the hotter the burn, the better the hash. These chips can go 70C no prob.
I would use bin .94 if it were more stable over 12 hours, but I use .98 and burn at 48C.

I have a Coolmax 500 PSU, and the whole thing makes almost NO sound, which is great.
Draws 102w, so it is approximately 1gh/watt.

At Eligius pool, where I have been stable at since sometime Tuesday,
I get 105GH constant, but it does burst up to 150GH on 128 second.

So every 28 hours, I get a 0.16777216 btc payout, and I've collected 3 so far.
As a first time miner, thats pretty fucking cool, but I did buy this at 50m diff, and did
not anticipate getting it at 390m diff.  No big deal, I bought this because I believe in
Bitcoin and supporting the network, not as a get rich quick ROI toy.

Heck, if bitcoin stays around 200usd, according to blockchained.info,
at 4.75billion diff, I'll still make 3.25usd a day if my electricity rates stay low.

Even though my miner is at 75% strength, I feel I got a good deal from KNC,
when I bought it I only expected what I have now, though the extra 43GH would come in handy.

I feel sorry for the guys that got miners that were 50% or more crippled,
the RMA process by KNC is BULLSHIT. Guys, I feel for you. Our best hope is:

A. Its a software problem, after all, there are 4 other unused VRMs on the board.
B. They make a bin that overclocks the working cores, getting the whole tub of shit up to speed.
    This makes the most sense to me, we're burning cool, a little hotter would be closer to normal.

Shit, in perspective I got a great deal, because I was one of those fucktards who actually put a 3200
dollar bid on a BFL Single Pre-order on EBAY in July. Thank God a bigger fucktard outbid me. Grin
Phew, that was a close one.

Well, good luck all, and whatever you do, keep mining. Cool

 

Good luck mate, glad you didn't win that eBay sale! My miner is mining at 102Ghs roughly and I've estimated 6-10 days to mine a full coin. Since Tuesday night midnight, which is 4 days, it's mined .4 of a coin on Slush pool.

I'm just glad I got mine without damage and in good working order and hope it stays that way for a long time to come. My thoughts are with those who received faulty miners in one way or another, that would suck completely. It's a big investment for any miner.



Everyone, how long does it take your Mercury unit to pull 1 coin?

So my Mercury is hashing at 105, which is fine, I paid for 100. However, I'd like to get the proposed 130 that it's suggested to be able to achieve. I'm waiting for the Die 0 Error patch that they're releasing, hopefully that will solve something.

Anyone else experience this on their Mercury and find a fix?

Cheers,

Also, I estimate 10 days to get one Bitcoin from my Mercury, what are you getting out of yours?

Hi all, I have the die0 problem on my Mercury and nothing has worked til now.

I turned off my main fan, and shoved the PSU in the case to get it hot.

The most I got was 62C, and after letting it run all night, there was no change in performance.

The only change I noticed was the dead vrm going from .25 Amp to .5 Amp-.635 Amp

I woke up, put 98.1 beta bin on, and now ALL vrm's function. I'm hashing at 140 steady.

I put the bin on, nothing else. No enablecores or hard boot. Just BertMod to check stats.

My temp is 70C. I pulled the hood off to cool it down a bit.

Nice to get it up before the next DIFF change. I will still pull a coin a week with DIFF at 523M.

UPDATE: Stabilized at 146GH using CGminer, running 98.1 beta BIN with BertMod, burning at 64C 155W.

It'll save folks going thru the same shenanigans I did.

Thanx Bitcoinorama, for the support you've given to the die0 sufferers.

I put the hood back on with the PSU stuffed inside- cooling it killed off the hashing.

All VRMs failed at 55C. I couldn't fucking believe it.

I put 98.1 official bin on, it got to 65C and took off again.


I'm gonna watch the temp, not let it go past 75C, and not touch a thing.

Good luck, jmevz, your upgrade should be a cinch.  Smiley

Don't forget to merge mine for namecoins.

UPDATE:
Mercury at 143Gh avg hash / 2.1% error rate
running 98.1 bin / Cgminer / Bertmod
burning at 69C 158W


Its done. Everything has been stable for 24hrs+.
Even the box it came in I've re-used sending packages.
Goddamned flimsiest cardboard I'd ever seen.

Incidentally, I ran my info at blockchain.info's calculator,
and at 90 BILLION difficulty, I'll still pull a penny a day
if btc is at 242usd. Technically profitable at 90 billion DIFF.

Ridonkulous.
