Cryptocoin Mining?

[thilanliyan]

Has anyone tried mining on the Z87 Sabertooth? I'm curious if the risers work and multi gpu etc. My Z87-K cannot use the PCI-E 1x -> 16x risers for some reason.

Not sure about risers but I'm running 3 7950s in my Z87-Expert. Are you using powered risers?

For some odd reason, it interferes with my GPU minining only on my i5 2500k & P67 deluxe with a 7970 & 5870. It did not interfere or affect my hashrates when I had a 7850 & 5870 in the same rig... Which is very strange. I am forced to run the command "-genproclimit=1" which basically tells it to run only on one core and I get about half the rate I used to get with all 4 cores and my CPU runs at about 50%+ CPU utilization which is also weird.

It doesn't affect the hashrate on neither one of my two other rigs.

Only thing I can think of is because 7970 is running on two threads (-g 2) or because I am using a riser for it. Neither of those two make sense, but those are the only two possibilities that come to my mind.

It is pretty decent, and it's such a joke to set it up on any PC or laptop... Just pop in the USB, transfer the folder with the files, and you're good to go. I have my 2GHz i7 laptop pulling the same numbers as my crippled OCed (@4.2) 2500k rig :$

Nice one. So this WILL increase wattage though it seems. I only have AMD rigs. 2x A6 APUs, 1x Regor 240 and an even older Athlon dual core. Are these even worth it or should I be using CPUs with @ least 4 logical cores?

Would low power consumption servers be profitable? I can easily get some Proliant stuff with 12 logical cores in a low density RAM config. Probably pull like 200-250 watts.

Is there a way to increase the khs for an nvidia GPU?

cudaminer -H 1 -i 1 -C 2 -l K7x32 --url stratum+tcp://stratum2.dogechain.info:3333 -u T_Yamamoto.xxxx -p xxxx

These are my settings. I tried overclocking the memory but that didn't seem to help at all. I did up my power limit to the max.

7870 2GB Sapphire Dual-X: 1050/1250 core/mem, 1.25v stock core. TC 15508 W 256 V1 I18 T1

7850 1gb XFX CORE: 860/1200, 1.1138v stock core, TC 7500 W 256 V1 I17 T1.

I have the exact same two cards you have (in two different rigs) so I'll try to give you some constructive feedback.

7850 Core is a monster, but it will only get 300kH/s at stock speeds.

Here is my 7850 bat file, this is the important stuff:
--thread-concurrency 8192 -g 1 -I 18

If you want to max out the hashrate on it, you want to overclock the core to at least 1050, ideally 1100+ and at least 1300VRAM. I currently have mine running at stock voltage (can't undervolt, but I can overvolt :\ ) 1000MHz core and 1250MHz RAM. It is the top card, sitting above my 7950 so it runs extremely hot which is why I don't want to push OC any higher. When I had it in my open case config as the bottom card with a 5870, I had no issues running it at 1100/1300. At 1050/1250 with I18 my 7850 gets 350kH/s.

7870 is a lot more simple... just underclock the core to 975MHz or somewhere within that range until you find a sweet spot. Leave the VRAM at 1250. With I18, you should get about 390kH/s on it. Report back with your results and we can go from there.

Yes, it will definitely increase wattage, rough estimate is around 100W for most CPUs, for simplicity purposes. I haven't personally tried XPM mining on any AMD CPU. If you get cheap or free electricity, it's worth a shot.

It is worth checking out the following comparison chart. However about a month ago, the primes/sec went down roughly 30% across all my PCs, and others have reported the same, so just keep that in mind:

Anyone mining Foxcoin? Difficulty is still very, very low. Almost negligible.

I was actually about to get into it when silverforce or someone else made a recommendation in this thread a week or two ago. I found a decent pool, registered, was about to fire up one of the rigs but then.... dogecoin jumped in profitability tenfold, so I think I'll stick with it for now.

 

[T_Yamamoto]

What do you guys think will be the next big thing after dogecoins?

I wanna get on the train before it leaves the station.

Kittehcoin pulled a Doge recently. From being in the utter dumps(.00000003 MOEW/BTC) to a much larger .00000066 or so, but with some major swings.

Ah, I heard about people with dummy plugs and so on but in my case it 'just worked'. Strange. But okay my setup is:
Mobo DVI to Monitor DVI
HD7950 DVD>VGA adaptor to Monitor VGA
(my monitor only has DVI and VGA)
And on the "Control Panel\Appearance and Personalization\Display\Screen Resolution" settings I have it set to only "Show Desktop only on 1" (that is the Mobo DVI).

Like I said that works for me and I never got the thing with dummy plugs etc. The only thing is, with this setup I only found one program which can monitor, HWiNFO64, since all the others only see the Intel HD4000. And I also had to hardwire into the card's BIOS the settings I wanted (925/1250 @ 900mV) since I cannot use Afterburner and the like to change anything. But anyway, my that's the only way I can get Gigabyte 7950 to accept my voltage settings.

Hmm. Just tried it. But when I have "Show Desktop only on 2 (Intel GPU), GPU stops mining and there's no load. Surprised you got it to work..

Oh god thats huge.

I just want to mine something that is easy on my GPU and with the hopes of it shooting up.

Edit: Just read this on Bitcointalk.. Wtf? Definitely ASIC.

https://bitcointalk.org/index.php?topic=361813.msg4840218#msg4840218

There are a number of Chinese factory mines, which were set up by very well financed people looking to get money out of China. By avoiding the Chinese bitcoin exchanges, and instead simply mining, they can stay under the government's radar.

Little information has got out into the English internet, but rumors have suggested that they are buying so many GPUs and mobos, that they have been buying GPUs direct from the card manufacturers by the 10000, and that some of the dedicated mining motherboards you can now buy were specifically designed in response to enquiries from these factory mines who were ordering 1000 mobos at a time.

There are also a number of Chinese vendors shipping Gridseed ASIC miners. These are reasonable value, and they are shipping, but supply is tight, and the big factory miners are basically completely draining the supply. At the moment, the only products actually shipping (well, actually none are shipping as the factories have closed for lunar new year, but the first shipments did go out just before CNY) are barely of beta-quality, and only available in kit form (no case, no PSU, etc.)

Of course, the other option is a bug in the pool. The initial prototype stratum server code had a bug in it which would cause it to accept invalid hashes, because it performed the hash check wrongly. Normally when a share is submitted to a stratum server, the server verifies that the hash generated by the miner is correct to the prescribed level of difficulty. It turns out that if the miner submitted shares with the difficulty set to -1, then the hash validation would be skipped, and any random spam would be accepted. A number of big LTC pools got ripped off in this way, by people running fake mining clients.

I'd give foxcoin a try if I were you

It actually went up to .000001 before falling down to its current prices.

Do you honestly think it'll be the next big thing?

No, but the difficulty is so low that it's worth getting in now and flipping the coins for a nice profit once it takes off in a few weeks/months.

Then, there is also KDC which I don't know a lot about, but I've seen some good things about it a few pages earlier in this thread.

 

[T_Yamamoto]

How easy is it to flip coins?

I've never really done it before. Like what do you use to exchange coins?

 

[nwo]

Use one of the many online exchanges . Typically, with the new coins there aren't many places where you could flip it for LTC/BTC/etc. But once it gains some popularity and serious network hashrate, more and more online exchanges will adopt it.

You'd have to ask the fox.

7870 is now getting a solid 370 at 975 with no other adjustments, and the system feels more responsive as well. the 7850s just weren't stable overclocked before but that could have also been the settings they were being run at, i can test again. worried about heat where they are right now, in my indoor rig on my desktop, but the other rig they were in was producing errors i thought. turned out one of the cards was just bad so i sent it back, which is why i have the 7870 now. gonna test again later today maybe if i manage to get a stable OC on the 7850. im thinking since one 7850 was just bad maybe the other two actually OC well (my buddy has the 3rd, sold it when i was only able to get 300khs out of it and needed cash real fast.

ed: testing at 975/1300 on the 7850 will get back to you.

ed2: 7870 now at 945/1250 getting 390 with small dips to 375 here and there but it seems to be stabilizing around 390 slowly. 7850 is at 345 with 1000/1300 core testing for temps, set it back to 8192 same settings otherwise. ommnomnom hashes, i just got 100 hashes out of that tweaking give or take. Maybe you guys can help me with my 7950s when they get back in from RMA they were only doing 530-560 before with the clocks at stock cause all of the cards were going bad from years of milkyway and seti@home lol. was getting 530-560 on all 3 but no amount of tweaking got them past the 600 mark everyone talks about them hitting, but that 7870 oc was counterintuitive as well so go figure

I pray that foxcoins gain ground since my dogecoins are gonna get cold. I have no school tomorrow so I'll spend 12 hours mining foxcoins and see how it adds up to dogecoins. I get like 500 dogecoins for 12 hours so we'll see.

If you get in early enough and are patient, you are almost guaranteed to make a decent profit.

Don't sell too soon. I lost 206,000 Kittehs for peanuts because I was scared even though it was already at rock bottom.

^^^This, 100x this ^^^.

I sold 200k doges for only 6LTC because I was like wow, they were worth less than 1LTC a few days ago, so I better sell before they tank again! At the recent doge peak, I could have gotten 20LTC rather than 6 if I waited an extra day or two... :\

 

[T_Yamamoto]

Well I guess I'm in it for the long run
