No. MaxCoin doesn't use scrypt-jane, it uses keccak.

In the 'Extra cgminer parameters' tab, type in:
--hfa-hash-clock <arg>

Where anything over 550 is overclocked. People generally get good results at around 600.


Note, you will instantly void your whopping 10 day warranty if you do this. This information is sent up to HashFast.com the moment you change it, so they will know.

On the other hand, it's not like HashFast is honoring their warrantees anyway, so it may not make any difference. But still, do this at your own risk.

It will always be easier and less risky for a manufacturer to sell a unit at the same price that they can get by mining themselves.

And if they do that, there will always be consumers willing to buy at that price that is willing to take on more of a gamble than a company run by a CEO would ever be willing to take on.

Companies don't institutionally make bets on horse races. People however do.

What's your core temperatures when you run in -4 C ambient? My cores are under ideal (they're between 57C and 67 C) at even 15 C ambient.

I believe this is a bug in the cgminer display. It doesn't just drop dramatically - it exact halves when the diff doubles.

I've watched it carefully through the stings when it does that - the Hashrate on Eligius itself doesn't seem to be affected, it's just the cgminer display. I'm not seeing CRC errors after switchover though. (3.11 on Windows).




HF-Engineer (Phil), does not have any input or knowledge of the MPP & Upgrade programs. That's an off-topic conversation for this thread anyway (see post 1) - please keep to technical issues.

I don't quite buy the "This is Windows's fault" argument. Bing.com runs on Windows Server 2012 and it's the 9th largest site in the world, and has the same stability as google.com.

But if you do in fact know of any specific issue in Windows that's causing any problems for you, please let me know those are and send the memory dumps - I live very close to Microsoft, and know enough people over there that can look at them for you.

Either way, I'm not looking for even bing.com level of reliability here. If the controller for the BabyJet is merely as stable as all of my other BitCoin / LiteCoin & AltCoin Windows based miners, and it can only run for 3 months before having to be rebooted, so be it. That's still VERY different than having the miner go down every day after 7 hours.


PS: I've now started running cgminer under cgwatcher. This helps. I bet (but don't know for sure) that the cgminer on the RPI probably has the exact same issues, and the watchdog process is just restarting it - same that cgwatcher does. Now that I'm running cgwatcher, my graphs on Eligius looks the exact same as it did on the RPI. Every couple of hours there is a steep down spike into the low 300's. I can now see on the PC it corresponds to cgwatcher restarting cgminer. I couldn't tell what it was doing on Minepeon, but I bet it did the same since the graphs look the same.

I found another minor bug (or may be the same one) on the 3.11 version of cgminer.

I'm on the Eligius pool - when the difficulty that the pool pushes down is 256, it will display double the hashrate. Once the difficulty goes up to 512, it will display the actual hashrate.

Not sure if this was fixed with the versions of cgminer that shows the actual hashrate at 256, or if we'll still see it halving the rate on higher difficulties?

Direct USB cable from PC to the BabyJet. Also only a little litecoin mining on the GPU. I also tried without anything else on the PC.

How do I get the cores warmer without overclocking? Space heater?

My PC cgminer crashes all the time on 3.11. I've never tried 3.12 on the PC. The longest I've ever had 3.11 working successfully is 7 hours - then it just quits (no error to diagnose).

The only stable platform so far is 3.09.0h2 on the RPI.

Is there a way to overclock the cgminer on the RPI? My cores are all now running at between 56C and 66C. Seems like a waste.

I have the exact same issue with cgminer on windows. I had to switch back to the RPI to get reasonable uptime.

Windows cgminer gives a bit faster hashrate, but not worth it if it's down for hours a day.

The real problem here is that Putin isn't a good politician. He may be a good statesmen but he can't sell it to the world.

There are similar laws actively being enforced in Arizona, Texas, Alabama and Utah against gay propaganda to minors.

Moreover, in Russia the law carries a >80% approval rating of the people. In the U.S. the same laws carry a < 50% approval rating.

If Putin was more of a politician, he would go up on stage and read the laws of the U.S. to the press, pointing the finger back at the U.S. and saying that the U.S. is doing the exact same thing - the only difference is that the U.S. is doing it without consent of the populous. There are lots of U.S. talkshow hosts that would just love to prance on a story like this.

I am solo mining, and just saw a block "accepted" within the last 15 minutes (according to cgminer with a 23.6K difficulty), but it did not show up in my Wallet.


I've never seen that before on any other coin. I've also mined hundreds of other Emerald coins, so it's not like I have a configuration issue.

I can't say whether this happened before - I just happened to have been looking at the cgminer screen at the time. And I've had a block after that one that was indeed accepted and showed up correctly.


I haven't been solo mining for long. Is this how an orphan block shows? Or is it something else?

Yip. Just saw mine at 1.3TB in fact. I figured it's just lucky streaks, because I also see 200gh/s every now and again. It's the average that counts.

The image is only 2GB. Did HashFast really send you an SD card that's smaller than 2GB? They sent me an 8GB card.

Or did you perhaps just try and copy the image on the first (90mb) partition of the card using a file copy, instead of following Phil's instructions to use Win32Diskimager?

Even if they did send you a < 2GB card (which I find unlikely since they're hard to find these days), you can wait for Hashfast to send you another one by next week, thereby losing $500 in mining in the process, or you can drive over to Wallgreens and pick up an 8gb card for $5. Your choice.

The PC does seem to help with the crash-and-reboot, but it doesn't actually improve overall hashrate.

I'm getting a 370 rate in all 3 these cases:

1) First day I ran stock software (no crashes)
2) Second day I ran on a PC (no crashes)
3) Since 5 hours ago I'm running on the updated RPI with the new constant crash-and-reboot "feature".  Average 2 full RPI reboot cycles per hour.

All of them however averages the same speed to Eligius to me (around 370). In fact crash-and-reboot might be slightly faster than the other two by about 3 gh/s.

I can see bigs dips on the Eligius graph during those reboots, but I think the rest of the time it's running faster to compensate.

I've gotten 4 reboots (RPI reboots, not just BJ) in 1 hour as a result of the: 3.12.0hf3 upgrade. Not looking too good.

Before the upgrade, my BabyJet + RPI has been running for 48 hours straight without any reboots.

Should I be concerned that my 3rd core is running so cool?

My unit hasn't performed better than 375gh/s since I got it. (As reported by Eligious).

On the original Minepeon it was reporting 425. Now after the 3.12 update it's reporting 751. But it doesn't change the actual 375gh/s perf I am getting out.

Can this have to do with the overly cool core?

You're right. Sorry. Your docs are very clear on this. I've come not to expect docs to be that good, so I've searched the forum and net but couldn't find anything. Should have gone to the docs first.

Anyway, donation sent from me - thanks for doing this!

Yeah, it's been 2 days now, and it's still returning 0.

It updated other values, such as networkhashps, blocks, etc. and I see the CPU being pegged at 100%. But the hashespersec stay at 0, so I can't tell for sure if it's doing anything.

Of course 'getbalance' also keep being at 0, but that doesn't say anything unless it's non-zero.

That's the Russia central bank trying to spread FUD. You can similarly accidentally become involved in criminal activity & money laundering by accepting any amount of fiat and giving back change.
