Topic: [ANN][TAG] TAGMining.Com is now the official pool of Tagcoin! - page 24. (Read 45656 times)

My transactions with default minimum fee take less than 10 minutes for the first confirmation. You can always do my technique of using 0.00010001 for BTC and 0.001001 for TAG, and those will get included in a block for sure within the hour.

I did the same thing today.  9 x 270Xs and all the fixings to run them.  Looking forward to trying to catch up to you guys finally.

HUZZAH!

Vesper,

If you want the ultimate in hash/watt... the 7790's will run at 250Kh/s at 30W at 48C... not sure how it will scale... but 4 of those would be 1Mh/s at 120W plus system power... the big problem is getting MB with enough slots to make it worth your while.

I can build a complete 2x280X mining rig including MB, CPU, RAM, HD, PSU for $1100AUD, it uses more power but is cheaper to build than a 4x7790 even with the GPU costing $100 each, the extra cost is a much more expense motherboard and cpu.

I may have to revisit the small cards though... thanks for sharing.

Just a side note... I have messed with the 78-series... and was never able to get more than 380Kh/s from them.

Testing out some more gear: 270X

In my never ending thirst to use more electricity, I'm checking out some more GPUs and equipment. As I mentioned to Fuse at some point, I've been doing the math on 270X and 7850 cards. Many of the 270X (maybe even the 270's as well) are under-tapped and under-valued I believe. The primary reason is their kh/watt ratio. They provide more hash per watt than the bigger brothers. These are also a little more available than the other cards, and if you find the right price it could be a deal.

Kh/Watt Ratio (lower is better)

None of this takes undervolting into account, as I overclock, but here's an example of what I'm talking about:

If I run 3 of these and they push 450kh @ 200w each = 1350kh 600w = .44 ($600 msrp)

2 280X units running 740kh @ 340w each = 1400kh 680w = .46 ($618 msrp)

And that 80 watt difference at the end of the month: 59.52kwh @ 11c = $6.54. Now multiply that by X number of rigs.

Every mining design is different, but I just wanted to present some of the math which led me to try these out. Ideally I would deploy these in groups of 5, but 3 or 4 would work as well.

The card

I picked up thisL PowerColor 270X. Well, technically I bought them out of stock, but it's not saying much as they only had 1 left haha. According to my research and math, it should've provided 430, maybe 450 on an overclock, and pull no more than 200w under full load.

I dropped it into a new asrock motherboard (which I also just took out of the wrapper), popped a BAMT stick in the USB port, and flipped the switch. In 30 seconds it was mining on Tagmining. I could hear the card's little cooler spin right up to full blast, it's not as loud as other coolers, but still noisier than my silent coolers.

To my surprise, however, the card--out of the box--was pushing 450, and that's just for starters. I've been working out some settings for it, and I have to say I'm really pleased with it. If these could be had for $200 (maybe even less, but not more), these would be great long term, because they use less power. I'll verify power with the killowatt meter soon.

With my settings, I've let it run for awhile, a few hours at times, to make sure it seems stable (0 HW errors, no lockups, etc). So far so good. Here's what I have verified:

Engine / Memory / KH / Temp / Watt (all @ 24000 TC, Intensity=20, LookupGap=2, stock cooler)

1030 / 1500 / 445 / 60C / 163w
1080 / 1500 / 467 / 61C / 168w
1115 / 1500 / 480 / 61C / 172w
1130 / 1500 / 485 / 61C / 174w
1145 / 1500 / 492 / 61C / 175w

Test Setup:

ASRock 970-Ex4, Sempron 145, 2GB DDR3
BAMT 1.2, cgminer 3.7.2
Room temperature: 24C
Idle wattage: 55w

GPU wattage was determined by taking the difference of total wattage at the wall and the idle system wattage.

Results look really good. ~492kh @ 175w. So 1476khs at 525w for $600. With my 280x's it would be 1500kh-1600kh at around 700w. That's a decent amount of power savings on multiple rigs.

I plan to get more of these as they become available. The Prolimatech MK 26 cooler appears to fit on these without issue, I'll look into that this week, as another box of them showed up today.

It's hit the low end of target spread.


Although this kind of information gets old quickly. I sold some TAG to make some BTC, to buy some hardware, to mine more TAG.

The other side of that coin is without those exchanges, the value wouldn't be as high right now. You make a valid point of course.

Now buying TAG for $1.25 a pop at the TAGbond exchange!

Difficulty of 175... the good old days of the 40's and 50's are over... must be the multi-pools... wish TAG was not on coinchoose or coinwarz... just screws up a coin... you would think that the multi-pool admins would be smart enough to realise that a coins that changes difficulty in one block is no use to a multi-pool.

Edit that - now 180!!!

NM.... Confirmed finally.... phewww.

FYI... it takes about an hour.

Oh I got a doozy for anyone that can help...

Sent a pretty sizable TAG transaction, and in my haste didn't pay attention to the TX fee.  It tacked on the minimum fee to the transaction, which I'm guessing is way to low.  No confirms, no TXID info on the explorer.  I resynced the wallet twice to make sure there wasn't something hung up in the process.  The transaction is being flagged in the wallet as sent, but with no confirmations... just in limbo somewhere.

What's the procedure for this?  Just wait until it confirms?  Does anyone know how long that takes?

I'm not a happy camper right now lol....

Well... I should be in the top 15... but competition is tough!!!

Risers

Ran across these while looking on ebay: PCIe 15cm risers

10 for $44 shipped isn't bad. They're not as long as the 19/25cm risers I've been getting for a few bucks more, but the price is nice. Figured I'd pass it on.

Congrats man, sounds like you're the next whale!

Well Done!!!

Can't wait till Friday... I am coming home with another new mining rig to boot!!!

Cool.  Just noticed I found my 50th block today!!  Hooray for me!  Not bad for a small miner.

FMD... 500MH/s pool hashrate!  1/2 of China has decided to visit Fresno. 

I just looked at the pool's conglomeration of miners. Why do I feel like one of the few non asian fellows near the top, lol.

As always, thanks for the effort and preventative/lookout maintenance man, it's a solid pool. Wouldn't mine tag anywhere else.

Unless there was a crazy temporary special for finding blocks lol.

I'm thinking this is a general TAG issue, as it's occurring across all the pools, some more than others(the bigger pools).

Vesper seems to think it's because of the network hash rate increase.  I hope that's all it is.  But it would still be nice to know why were just now seeing it with this and not 3-4 weeks ago when the network hashrate was at a high as well.

I know I probably sound like Chicken Little, but I want to make sure the issue isn't something I can help prevent on the pool.

Yeah, I retract my statement about the orphans  seemed when I checked earlier but I didn't check again before posting.  

Do we know if other coins are experiencing similar issues?  Just wondering since it seemed to come on suddenly.  ie, is it a TAG issue, or a general latency issue. 

These orphans are starting to piss me off.

We are seeing quite a few of these, as is botbool.  It's not as pronounced on the smaller pools, but it's still happening across the board.  I just wish I knew what the issue was so I could address it.  Like if it was something that needs to change on the pool, I'd like to just change it and move on.

If anyone sees or reads anything, please let me know.
