Cryptocoin Mining?

[geokilla]

Ayup, it's going to be quite interesting to see what happens to the entire altcoin market once the doge block reward halves. If doge price doubles then everything will continue status quo, whereas on the other extreme if the price stays constant then it's pretty much a given that close to half of the current doge network hashrate is going to go elsewhere... which could easily drag down profitability across the board when you consider that half the current doge network hashrate is around 50 GH/second. (The LTC network is 'only' at 75 GH/second currently for comparison.)

Anyway, that's why I'm definitely hoping that doge price will adjust to compensate.

I stopped mining DOGE a long time ago because I felt I wasn't getting anywhere with it. There's way too much network hashrate.

And this will mine Maxcoin without a recompile?

MAX is dead. But to answer your question, no.

I have tried the Z87-K with 2 GPUs on the 16x slots but the 1x slot won't work at all with 1x->16x powered risers (the second one is covered by a GPU).

I am looking at the MSI Z87-G45 and Gigabyte Z87X-UD3H. My plan is to have 2 16x slots in use for occasional gaming, and 2 or 3 1x to 16x risers for additional cards strictly for mining. Which of these is the proven option.

Windows 8.1
i7 4770k
MSI Z87-G45 or Gigabyte Z87X-UD3H

2 290x's
1-2 79xx cards
1 69xx card

The only thing I care about is 2x slots for gaming/mining, and 2-3 1x slots to use for risers (at the same time).

It seems hard to find anything which can use most of the slots and they seem to disable certain slots depending on how you populate them.

My thought on the Z87-G45 Gaming would be to use the first and last slot with 1x to 16x risers, and the 2 PCI-E 16x slots with cards in them.

Has anyone used this board, or the UD3H like this, successfully?

Do not store coins in an online wallet.

Roger that.

I decided to try setting up a worker on my laptop just for the heck of it. AMD's VLIW5 architecture was a mining all-star back in the day, right? However it's giving me an error when I try running cgminer. It says "GPU 0 failure, disabling!" Is there any way to work around this? I set it at intensity 10, thread concurrency 512, and GPU threads 1. Running Catalyst Mobility 13.9 (my desktop is running 13.12; the mobility download tool won't properly download mobility 13.12).

 

[IEC]

As a corollary to "do not store coins in an online wallet" I would add:

"Do not store coins on a pool" - always use the lowest auto payout to a secure wallet that is possible with the pool. Actually, to take a step back, make sure the pool is legit first before even using it. I lost ~.1 BTC worth of mining to the scammers at BitClockers back in the BTC mining days before I realized they were never going to pay out. I consider it an inexpensive lesson.

 

[Red Hawk]

I found someone online asking about the same error I was getting (error 55) and someone responded who said they had resolved the problem by entering the following. They even had the same GPU as my laptop, Mobility Radeon 5470.

https://bitcointalk.org/index.php?topic=270452.0

Following the password, they had:

-w 128 --lookup-gap 2 -g 1 -I 17 --temp-target 75 --temp-overheat 80 --temp-cutoff 90 --gpu-powertune 20 --no-submit-stale

I tried entering it in and it didn't work, but it did do a nice job of crashing my display driver.

I have a number of Z87X-D3H mining rigs. (not UD3H, but I'd guess they're pretty similar).

The 1x slots cannot be used if there is a card in the 16x (physical) slot furthest from the CPU. The mobo detects the presence of a card here and electrically disconnects the 1x slots, and routes their signals to the big slot.

Further, I have never been able to get this mobo to detect more than 3 GPUs, no matter how they are connected.

 

[KlokWyze]

Someone placed a market order and sold at whatever was the highest price they could get, seems they had enough BTC to wipe out almost the entire orderbook so it went down to $102.

Dunno how you could be so stupid. Well whoever got the coins made 6x profit in a day.

All I can say is bwahahahahahahaha

 

[Red Hawk]

Ok, I lowered the intensity on my 5470 and it's not reporting any errors or display driver crashes. The command prompt window is now going completely blank upon running the batch file. However, MSI Afterburner is showing GPU temp climbing to ~64 degrees celsius, and the PC is chugging. So something's going on. At the same time though, Afterburner is not reporting any GPU usage, and Dogehouse's worker monitor is not showing my laptop worker as active. Is it possible that my laptop is just not reporting the GPU load to Afterburner and the Dogehouse monitor just takes some time to update?

Thanks!

The manual for the D3H states that if the 4x slot is in use the 1x are slots are unusable, thanks for clarifying that.

1 x PCI Express x16 slot, running at x16 (PCIEX16)
*
For optimum performance, if only one PCI Express graphics
card is to be installed,
be sure to install it in the PCIEX16 slot.

(The PCIEX16 and PCIEX8 slots conform to PCI Express 3.0 standard.)
*
The PCIEX8 slot shares bandwidth with the PCIEX16 slot.
When the PCIEX8 slot is
populated, the PCIEX16 slot will operate at up to x8 mode.
1x PCI Express x16 slot, running at x4

*
The PCIEX4 slot shares bandwidth with
all PCI Express x1 slots.
All PCI Express x1 slots will become unavailable when a PCIe x4 expansion card is installed.

When installing a x8 or above card in the PCIEX4
slot, make sure to set PCIE Slot Configuration in BIOS Setup to x4.
3 x PCI Express x1 slots (The PCIEX4 and PCI Express x1

1 x PCI slot

The UD4h states:

The PCIEX4 slot shares bandwidth with the PCIEX1_2/3
slots. The PCIEX1_2/3 slots will become unavailable when a PCIe x4 expansion card is installed

http://download.gigabyte.eu/FileList/Manual/mb_manual_ga-z87x-ud4h_e.pdf

I hate copying from mangled PDFs.

So the UDxH with the one extra PCI-E 1x slot should support the first slot and then the three long PCI-E slots? At least it doesn't claim to disable the first PCI-E 1x slot.

The MSI G45 Gaming on the other hand, doesn't say anything about the PCI-E 1x slots. It does say you can use 3 cards in the 16x length slots at 8x, 4x, 4x.

The ridiculous +170% MSRP markup NewEgg.CA graphic card prices are the lowest of any retailer in Canada. Amazon is a joke in Canada. @*&$ NAFTA.

Really? I saw NCIX had a couple of reference 290s for under $500 about a week ago, and memoryexpress in Alberta has not done ridiculous markups either but they never have cards in stock. Haven't kept up tbh.

No, this has happened to me sometimes, AFAIK it's crashed and not hashing.

I would start at the lowest possible intensity to start with. Go with 5 or something. Once it's working, up the intensity.

Also, I assume this is a laptop that you're willing to lose to heat? Because crap happens. People's GPU fans die, things like that. In a laptop, that's a lot harder to replace. Not to mention, the CPU and GPU are a lot closer together and with a lot less thermal headroom.

 

[JDG1980]

Well don't tell GPU prices about the BTC crash.

Higher than they've ever been, and substantially so.

Newegg must thinks folks are crazy, bam 280x's >$500, 270x $300. lol wow.

That's utterly crazy. Now the price hikes are hitting Pitcairn too? Fortunately it doesn't look like anyone else has followed suit yet.

Strangely, they still have a 7870 (same silicon as the 270X) on sale for $179.99 (plus an extra $30 rebate).

Although 7870 is comparable to a 270/270X in terms of gaming performance, it is lacking behind the 270s in terms of mining performance. 270/270X is capable of pushing an extra 70-100kH/s compared to a 7870.

 

[zhorx]

No its not.
Its 380-400 MH/s for stock 290; 450 MH/s @1100MHz



That's because VRAM barely gets used, and it stays at 150 MHz while crunching

Hi! Just wondering the settings you are using to get that hashrate with the 280x? I've been trying many different combos and can't get more than 160M/h per card. I was using a config file with more options so I stripped it down but still no joy.

"gpu-fan" : "85",
"temp-cutoff" : "91",
"temp-overheat" : "85",
"temp-target" : "75",
"log" : "5",

"keccak": true,
"kernel" : "keccak",
"api-listen": true,
"api-network": true,
"api-allow": "0/0"

Could you please let me know if you think about anything?

Thanks.

The halving is coming. In 2 days, the rewards for finding a dogeblock will be halved.

I pray that the price of them goes up.

[SunnyD]

The "Anti-Keiser-Coin" has been announced and will launch in two days. (Anti-MaxCoin)

Do I need to set up a pool for this one?

Do I need to set up a pool for this one?

If I can make a few BTC in a week with my 3MH/s, like others have done with maxcoin, then by all means sign me up and count me in!

hey guys I have to warn you about bter.com

I didn't do my homework and it seems to be a very poorly run site with no support. A lot of people have lost a lot of coins so I'm trying to save you the trouble. I've got a lot of coins stuck there now.

It kind of does - it mentions the fact that the PCI-E x16 slots are all Gen3 which means that they're all connected to the CPU. So instead of driving the third PCI-E x16 slot from the PCH they split up the CPU Gen3 lanes to 8/4/4. MSI is one of the few (if not the only?) manufacturer that does this on their 'mid range' motherboards.

Have you tried messaging them on QQ (Chinese messaging service). They apparently aren't too quick on responding to emails, so might be worth a shot.

Are you using cgminer or that arOpenCLMAX?
arOpenCLMAX is 1/2 of cgminer hashrate

Here the latest cgminer 3.7.3
http://maxdl.1gh.com/cgminer-windows.zip?nocache=0.03300142637453973

Im on R9 290, pm IEC for 280X

Is 420MH/s normal for Maxcoin mining with a R9 290? And 350MH/s normal for a 280X?

I ask because keccak mining seems to have my GPUs running about 12C cooler than normal... none of them are breaking 68C which makes me think they're not running at optimal settings... but if they are then all the better, less power usage

I just add "--keccak --no-submit-stale" to my usuall scrypt CgWatcher profile (under arguments)

 

[IEC]

So, what's the next Maxcoin?

I made 0.15 BTC on it since last night but price and profit are declining - combined with DOGE's average reward per block halving in a few days, it'll be a 1-2 punch... unless DOGE's price doubles.

The lowest intensity CGMiner seems to allow is 8, it gives me a new error message if I try to set it lower. Even on 8 the same thing is happening, with the blank command prompt window. And I know this could wear out the laptop; I'm really just getting it setup for the heck of it. It's not my 5470 could hash anywhere near enough to make a real difference alongside my 7870.

I've been hashing dogecoins for the greater part of the day, and I installed the Dogecoin wallet app, generated a wallet address with it, and linked that address to my Doge House account. I've had the Dogecoin wallet app running the whole time my PC's been mining, but nothing is showing up in it yet, regardless of if I change the automatic payment threshold is set to 500 or 150000. Is there something else I need to do with setting up my dogecoin wallet, or do I just need to wait a while for a transaction to process even when auto-payment is set to 500?

 

[zhorx]

f1sherman, I'm running on Linux. What I've done is pull the git tree here:

https://github.com/Eropi4/cgminer_keccak

and compiled it with keccak support. It's made from cgminer 3.6.6.

I'll be doing more digging and will let you know what happens!
