Miners would notice they are not seeing as many shares on their stat page as they see in their miner. Within hours someone would raise hell. Now its just blamed on luck.

Mind you, it could very well be bad luck and coincidence, but deepbit 24hr luck is now down by almost 40% 45% now. Is that a record? Bitminter hasnt found a lucky block in ages. And mystery miner doesnt seem to have any effect on global hashrate. I dont claim to know how it would or could work, but it looks suspicious to me.

Interesting read Organ.
I do wonder if perhaps you are not misinterpreting the data; when a round starts, you get fresh work. Even assuming zero delay from the pool, and zero network latency, only the fastest miners are going to be able to submit shares within seconds. Slower miners may take up to a minute or more before they submit their first share.

I wonder if that by itself couldnt cause both the drop at the beginning of the round, and the slow spike afterwards. After all, deepbit rounds are very short, and I wouldnt be surprised there a lot of slow and clueless miners on there.

As for the poll:

Bitclockers.com    - 2 (0.6%)

Will the one person besides the pool admin who voted for bitclockers please stand up?

To get this back on track...

Thin foil hat scenario; deepbit is having  terrible luck (down -33%), so do some of the other pools Im looking at (bitminter for one, its also down by 30% at least). At the same time, mystery miner seems to be increasing his output (5 out of the last 20 blocks!), and the overall network hashrate is going slightly down, not up as youd expect if this is LargeCoin.

Is it somehow conceivable mystery miner is "stealing" blocks? Sniffing network packets? Bitminter and deepbit are hosted by the same company I think.

get in touch with BFL. Even if they wont ship you a test sample (you can always ask!), at least they should be able to give you some information and remote access to one.

Why the sensational post title? Clearly you have some kind of connection problem, or a full disk or whatever. You should have

blocks. Since you dont, its completely normal you dont see recent transactions or balances. Check your firewall, your drive or whatever needs checking.

run it again after you added (or removed) a card, then reboot, then try again. You may also try with -f

sudo aticonfig --adapter=all --initial -f

You can use the transaction count of 1 as filter to detect the Mystery miner. Its a crutch but would be fairly accurate for now.

If you could add another zero to that sum, you might want to look at doing an altera hardcopy. Its the logical next step after FPGA; significant power consumption and (given enough volume) cost advantages, without the excessive NRE of a full custom asic. Should also be much easier to develop, if you have a working FPGA implementation, and a bundle of cash, you have all you need.

Anyway, needed a VPS, so I signed up.

Im building an oil/water cooled setup.  The idea is simple: invert the motherboard, place only GPUs in the oil bath, pump the oil through a cooler, and in my case, the cooler will be placed in the filter of a large pond.

I have been doing experiments with an old frying pan and aquarium pump and an oil cooler. Lessons learned so far:
- mineral oil here is difficult to find at reasonable prices. I am going to use vegetable oil and replace it every year if needed.
-  As expected, the aquarium pump (even though a very powerful one at 1600L/H) was utterly inadequate. I gave almost no flow when the oil was cool, only at ~60C+ did the oil become fluid enough to generate some flow, but still way too little. I ordered this:
http://www.ebay.co.uk/itm/New-12V-DC-CPU-Cooling-CAR-Brushless-Water-Pump-DC50C-1240-High-performance-/120828500685

And I hope that will work better (4m pump head is a fair amount) because the others need 24V and thats no so easy to generate at those amps. 12V can be powered by a PSU. If its still not enough, Ill may just add more.

- air cooled, my small radiator was completely unable to cope with the 1750W frying pan. That too was expected. Submerged in cool water it seems like it should work, although I have yet to generate high enough oil flow to be sure.

- reinforced garden hoses seem to work fine, even at 60+C they didnt become weak. They are cheap (I have to run them a few meter distance to the pond). Dont use clear tubing if you opt for vegetable oil, sunlight is the prime cause for oxidization (=oil going rancid), far more than humidity or air.


Ill post some pics later when the pump arrives and I begin testing with an actual rig.

While the above chart seems to work fine, I do see all recent blocks as orphaned. I suppose thats a related problem?

FAKE!

It also sounds as if your stick has gone haywire. Try another stick.

I still stand by my point that you are overstressing your motherboard way beyond what is was designed for though; it may or may not work for some time, it may go up in smoke, it may give all kinds of weird problems. Its not worth the risk and time troubleshooting IMO, just get some powered risers. Even if it wouldnt solve your current problem, it will likely prevent other, and possibly more serious ones, like a smoking motherboard.

This is probably not a good idea. No way that mATX motherboard was designed to deliver that much power to the PCIe slots.
Remove one or two cards, and see if it runs stable. If it does, you are going to need powered risers.

The easy solution for Ubuntu: open Ubuntu software center, search for "IcedTea Java 6 web start". Install it. Done .

Subscribing as this looks like a perfect fit for my oil cooled rig.

one small comment; rather than removing the cpu heatsink, I assume you could use a PCIe16x cable with their male/male adapter and put the entire board a bit higher. At least Id give it a shot.

To be clear, Im not implying its not random. Im just curious how rare it is.

LOL, talk about a streak of bad luck 
I just saw your last 10 blocks averaged a hair under 4M shares per block.

Anyone want to calculate the odds on that?
