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!!!

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

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.

It's hit the low end of target spread.

0.001789 BTC =  80 PHP = 1 TAG
0.002236 BTC = 100 PHP = 1 TAG

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

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.

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.

[ny2cafuse]

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

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!

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.

[24Kilo]

Ideally I would deploy these in groups of 5.

What motherboard and PSU will you use?

Here in Australia PSU are expense... think $200AUD plus for a good 850W and around $400AUD for anything decent over 1000W. This is why I have been sticking to 2 X 280X rigs which work very well on the $149AUD Antec 750W PSU's that I have been getting. A Corsair HX750 is $215AUD.

Are you running the scrypt.bin file that you posted?

I've been exploring the ASRock 970 Ex4's extra pcie slots, the 1x. It has 3 x16 slots, and 2 1x slots. I've successfully plugged a card into them and mined. For BAMT to use all 5, I have to tweak the driver setup a little bit. So I'm going to explore that some, mainly to run 4 GPU's because my PSU preference won't handle more than that.

If I have to, I could move to the ASrock which supports 4-5 GPU's by default. There's a place I can get them for about $160.

As for PSU, I've been trying out 1050w units, specifically Corsair HX/AX and Thermalteke TPG-1050M. I'm going to grab the Seasonic 1050 once I get more GPUs.

I do have the scrypt file loaded on all of my copies of BAMT, but it doesn't do anything for the 270's as it's designed for the Tahiti series chips (280x/79xx), and the 270x series is the Pitcairn.

And here is me thinking that the 270x cards were my little secret as value for money cards!  I picked up a Sapphire Vapor 270x a few weeks ago and was happy with it hashing at 460kh/s.  I took vespers tip and increased the thread concurrency from 15232 to 24000.  Bang! I'm up to 493kh/s with virtually no extra current draw.  It's running happily at 63 degrees C at 74% fan speed with 2 other cards spinning away next to it.    

There must be something different about the new X series card that benefits from such a high TC.  I've got a 7850 which is also a Pitcairn card that gains virtually nothing running it higher than 8192.  Even my 7950 Tahiti's aren't really interested in anything higher than 16384.

Glad my post helped you out a little bit

These cards are a smidge different, they seem to favor 24000 TC and/or higher speeds. What's strange is it seems they all like engine speeds in the mid 1000's-1100's regardless of brand or chip, as if there's something in them which can be unlocked.

I'd been hearing faint rumors for awhile now that AMD had a tiny subdivision working on scrypt-focused ASIC cards. If it's true, it would be revolutionary. Makes me wonder if they're letting some of that code into the wild in these cards, with how they're performing. All rumors of course, but makes you wonder.

Of course, now that I want to pickup like 10 or 12 of these 270X's, i can't find them anywhere.

Hmmm... I am on my way today to pick up my order of 280X's... maybe I need to pick-up a few 270X's as well... maybe build my first 3 card miner... that sounds like fun!!!

Checking the stock of my local MSY now... it's all your fault John!!!

EDIT - The big news could that the 270X's run cooler... a lot cooler and cooling is a big issue for me and probably for you as well, John... if the 270X's run 10C cooler without any aftermarket cooler or risers... that is even more economical... what is the concensus... Fuse... do you have anything to report? Cooling a huge for me... I have a few of my 280X's throttled back to keep them running under 84C on these last few hot days.

My order comes in over the next couple of days with most of the GPUs coming Friday/Monday.  So I'll need to get it all set up, and I'll let you know.  I'll be running 3 cards on the MB, a ASUS M5A99FX PRO, with a Cooler Master V1000 PSU.

Just a heads up... I'll be pulling my miners to mine Coinye tonight and maybe tomorrow.  I hate Kanye West, and this coin has already been reported on TheVerge.Com, the Wall Street Journal, RapGenius, etc.  Pure pump & dump.  It starts at 7PM PST... so heads up

The one I have is still in the 490's and enjoying itself at 60 or 61C. The room its in is 24C. They definitely run cooler, especially since they're pulling 175w max vs the 340-350w the 280x's are pulling. With the stock cooler I bet it would be a good choice for you. If you can get your hands on 1 to 3 of them, do so. You can always hotbox test it yourself

I'm ready to buy like 4 or 6 or 10 of them, but all I have is amazon gift cards and amazon is sold out lol.

Just read this... shaking head... shall we all hit it hard?

Is this thing worth even wasting hash-rate on it?

[ny2cafuse]

I think it will be big just because of the media attention that his lawyers are pouring into it.

Time, WSJ, Washington Post, etc., etc., etc.... all reporting on this.  I think the initial launch will be very much like Doge, where there will be a ton of hype, and a large following just to see how this will pan out with his lawyers over the next few weeks.

So I'm going to throw some hashing power at it for shits and giggles for a day or two.  A day of mining isn't going to kill me.  But if it goes big, it'll be well worth the days effort.

[vesperwillow]

I saw those cards earlier, but I can't choke $30 or more over MSRP when prime has them for $209 usually.
