Topic: [ANN][TAG] TAGMining.Com is now the official pool of Tagcoin! - page 19. (Read 45656 times)

Actually, the non-x card is the next 6-9 that I will be purchasing.  I'm just trying to go Amazon to be able to use BTC via Gyft.  If I don't pull the trigger on those today, I'll be piece-mealing a bunch of 270Xs.


I am with you guys 100%.  In fact if you look back in the main thread, I was one of the first people, if not the first person, to bring up the unusually high orphan rates.  I understand that people are saying that it is correcting itself, but lets say TAG gets as big as LTC.  Take one of the top pools, GiveMeCoins, and they are hashing at about 8-9GH.  That's 8-9 times what Botpool is doing.  If we're seeing issues with one pool at 1GH and the rest equaling about 1GH, what is going to happen when the network hits 10GH?

I agree with your concerns and complaints.  It's very difficult for me to look at the block page and see it dotted with ORPHAN ORPHAN ORPHAN ORPHAN.  It's especially hard when you can't do anything about it because it's not a server issue.

I think if anything is to be done about it, the difficulty needs to retarget every X amount of blocks.  I say 10-20 blocks.  That's every few hours if things are running smooth.  I think it would help to even out the difficulty, and reduce the issues we're seeing.  I really do think the wild swings are what are causing a majority of the issues... as well as Botpool being such a blubbering whale in Asia.  But I'm working on that  .  

In the meantime, I think we should campaign for the difficulty to retarget less often.  Even if that doesn't solve the orphan issue, it will smooth out the round targets, and stabilize the rewards a little bit.

I want to try 270's, but they're as scarce for me as the X's lol. I have a feeling Amazon will get some in today.. fingers crossed.

All my rigs run Windows... I don't own a dummy plug... my mining rigs must not know about this... so don't tell them.

All my rigs run without a monitor, keyboard or mouse plugged in after I get them running and stable.

As far as I'm aware, you need dummy plugs with Windows.  Linux doesn't require them. However there appears to be no hashrate penalty in using them but when a card is connected to a live monitor, there is a price to pay, which I never really realised until tonight.  That would explain why I have 2 x 7950s that are identical but one runs a bit faster than the other as one is connected to the monitor and the other one has a dummy plug.

Is the dummy plug(hot-plug) necessary for the 270X... the 270???

All my 280X's run without a hot-plugs just fine.. or at least I think so... maybe if I used hot-plugs I would get better hash-rates.

Me thinks my next rig is a 3x270...

OK. To quote myself.    Spent a few hours testing both the 270X and the 270. One common thing I've discovered is that neither will hold 1500 memory speed (for me) for more than about 1/2 an hour.  I've found that the sweet spot for both cards is around 1120/1475.  The 270X will crank all day at about 483kh/s with a dummy plug attached and about 468kh/s if it is doing double duty as the card connected to the monitor.  Similarly the vanilla 270 will do about 478kh/s and 463kh/s if it is attached to the monitor. 

So there you have it.  In my opinion the 270X is a 5kh/s better card.  Is 5kh/s worth the extra money?

PS: All testing done at TC 24000, I 20.

Make that 2 orphans in a row, another hour wasted.    I'd go and mine DOGE except I've already got over a million of them that are worth sweet FA.  Might go join 24kilo over at the EAC ranch!

John,

I agree wholeheartedly... with an orphan rate of nearly 33%... just check the 24hr stats - 61 blocks found - 43 valid - 18 orphans... TAG is no longer a profitable coin to mine for me... and as everyone here knows I am a big TAG fan and been mining since the beginning as well... Mark and the team must address this... it is vital for the long-term usefulness of the coin... and if Mark does not know how to remedy this problem... then the coin faces a real long-term confidence issue.

Fuse is in no way implicated in this fiasco... he has set a gold standard for pool admins... and he has to be extremely frustrated to see this happening after all the hard work, energy and real money he has invested in this pool.

I have moved on... I am mining EarthCoin... the other coin that I believe has real potential and usefulness... now and in the future... and it is reasonably profitable to mine... at least until it starts getting hit with multi-pools.

Fuse... you know I will support any pools that you choose to open to counter your losses from TAG.

EDIT - Another orphan - #28256 - that makes two in a row.

Fuck this for a joke... Pool is hashing at nearly 400Mh/s, busts it gut for over an hour and a half only to find another fucking orphan... (Block 28546).  Sorry Fuse, not having a go at you, it's not your fault, just venting my frustrations.  If Mark doesn't pull his finger out and fix this problem, I'm moving on and that's a big thing for me to say as I've been mining TAG since day 1 as you know.

Didn't post this on the main thread for obvious reasons.

Fuse.  Have you considered the non "x" version of the 270.  See my post earlier on this page.  It should be easier to get than it's "x" rated brother.    I've had one running for 24 hours happily at 469-473 kh/s (expect for an hour or so when the bride unplugged it to using the power point to vacuum the room - I kid you not... Came home and wondered why the miner was down... Sheesh!

As I said in the earlier post, I think they are good for ~ 480kh/s if not also powering a display. In fact, I'll yank the 270x out of the other miner and put them together and report back with a back to back test. 

3 times now, I've put cards in my cart on amazon, and by the time I check the cart total, they're out of stock.  Damn it, people... let me buy all the GPUs!

I know, I know... one-click-buy.  I'm an old fashioned kind of guy.  I like tallying up big orders, and ordering everything all together.  I've still got about 40 empty amazon boxes in the living room waiting to be broken down for recycling from Xmas.  If I can reduce the number of boxes that come in, the wife will be happy lol.

Update, #4 finally took a dump and got marked dead, after about 50 hours of hashing. Give or take, I can't remember exactly. Restarted it and so far so good. No HW errors when it died, just died.

It's back to hashing happy. It seems to remain lower than the others for output. Might lower its overclock if it happens again.

I don't have one I would absolutely say blows the others away. PowerColor AXR9 and Sapphire both are doing a bangup job, and it looks like the VisionTek's are as well.  The cooling design of the Sapphire and PowerColor appears superior to the Visiontek's (the copper piping), but all of them are doing fine right now. Picture:



0 - Sapphire Dual-X
1,3,4 - Visiontek
2 - PowerColor

Physically the layout is: 2,0,4,3,1

I would buy them all again. I had a chance to get some more today for MSRP but couldn't convert the BTC->AMZ in time.

Use this pool at your own risk... the last found block was 27540... the pool is reporting this block as needing 153 confirms... I have not been able to reach admin, LeftToeCut, for several days... this will be my last dealings with this pool... I no longer support or mine at this pool... I would recommend all miners at this pool to contact admin through Tagyak, his user ID is Ingvar, to try and motivate the admin to respond.

The admin was due to be home from hospital by the 10th of January... I have not had any response from the admin since the 9th.

I believe the admin is an honest person and will honor his obligations... I could be wrong and if so it has cost me dearly... please do you own due diligence.

Interesting. I'll go make a comparative study on them. So a 5 slot motherboard is also cheaper than the 6 one from ASRock.

What brand do you recommend for the 270? The guy in Taiwan has them all priced within 5 USD of each other.

Deleted.  See my previous post for updates.

John,

Thanks for the information. I still have yet to spec my last miner... and I am not sure what it will be... 2x280X, 3x270X, or 3x270... I currently have a set of Sapphire Dual-X 280X's running 760Kh/s each at 1.187V... pulling 640W at the wall with 80W system load... so 580W for the cards... that is roughly 2.375Kh/s per watt... which is right on par with the 2.73Kh/s that vesper is getting with his 270X's.

Sapphire Dual-X are the most trouble free cards I have run... they just hash... hard with no fuss or muss... I use Sapphire TriXX to regulate voltage... start cgminer... get it up to speed... exit TriXX... and gain another 20Kh/s per card... once TriXX fixes the voltage... the cards will hold that voltage even after you exit TriXX.

If I can get the system load reduced further by turning stuff off in the BIOS... that will make them even more efficient.

The ASUS cards are going to equal or beat the Sapphires... just have yet to tweak them.

So decisions... decisions...

Funny you should mention that as I was just about to post about my experiences with the vanilla 270..  OK, I took one for the team today and bought a vanilla Sapphire Dual-x 270 which was $40 cheaper than the top shelf Sapphire 270x Vapor that I bought a week or so ago.

Now I can't get my 270X to run at 492kh/s reliably like vesper can, it craps out after a while at 1500 memory speed but I have got it running happily at 1130/1475 producing 487kh/s.  OK. Plugged the vanilla 270 in today and afterburner gave me default settings of 945/1400 which produced 405kh/s, so far so good.  Slowing pumped it up to the maximum that afterburner would allow which is 1050/1500 and got 454kh/s.

I'm sure that it will go a bit harder but even after downloading the latest afterburner beta, it would not let me go any further.  If you look here: http://www.hardware-360.com/sapphire-radeon-r9-270-dual-x-2gb-review/5/ someone has got past the limitation and I'd really like to know how.  

Any ideas?

EDIT1:  Found "extend official overclock limit" checkbox in afterburner settings.  I'll report back how I go.  
EDIT2: Going for broke! Cranked it up to 1145/1500. 10 minutes in, holding at 489kh/s.  I'll be surprised if it can hold that as it only has 1 x 6 pin power plug. Stay tuned for updates!
EDIT3: Just checked the computer so I could post a 1 hour update (was still cranking after 45 minutes).  Damm thing had rebooted.  Doubt it is due to the 270 card as it did it randomly earlier before I even installed the 270.  I think the 7950 in the same rig is playing up.  Pulling the 7950 and leaving just the 270 on that miner.
EDIT4: OK. Yanked the 7950 and rebooted with the 270 powering the display.  Crapped out within 1 minute so 1145/1500 must have been REAL close to the edge..  Reset to 1130/1500 and is chugging along at 469kh/s.  I'm guessing that if you throw a few of these at a miner they SHOULD be good for ~ 480+ less 10 for the one powering your display.
EDIT5: 2 hours later.  Card is still chugging along happily at 469 whilst powering the display.  Temp 66C, fan speed 50% on a hot summers night in OZ. Conclusion: Good for 470kh/s minimum and a bit more if it's not powering a display. Personally, I'll be buying the 270 over the 270x.  
EDIT6: Next morning and it's still cranking so 1130/1500 appears to be a stable minimum.

Anyone have some good hash rates to share from R9 270 cards?

With my 5 card test unit, I really like the power savings (almost 100w) over my other rigs, and it's providing 200-400kh more on average as well. With the Prolimatech aftermarket coolers, I bet the power savings would be another 20-60 watts. For the watt/hash, these are surprising results, but the variance is noticeable, and I'm not sure how "Stable" the system is yet. I've had it running like this for a few hours. Will know for sure when I wake up in the morning.

Of the 5 I have running right now, 2 of them at any given time are at 490-492, with 2 more varying 485-492, and one of them perpetually 480-485. Varies constantly. Power usage remains about the same, 975-985 watts, which puts it in the 175-180w range for each. When i go back downstairs to the test rack I'll glance at the meter again.

The Sapphire and Powercolor have been the most rock-solid stable on an individual basis, with the visiontek doing a great job speed-wise but with some slight variance. I'd order them again in a heartbeat though for the right price.

I think I'm just pushing the motherboard/riser combo to the limit. No cooling issues so far. I have USB risers coming this week, I'll see if that makes a difference. FWIW, all 5 are using the same gpu settings, I'll share below.


Congrats! Hope it works well for you, let me know if I can help.


Depends on the rack and rig. I use a mix of Seasonic 850 Gold Plus and 850 Platinum, Corsair 1050HX & AX series, Thermaltake TPG-1050M. I've had no issues with these guys yet. Guess I've had good luck so far. I also have 1 Raidmax RX-1000AE which just died after 3 months of use. Lifetime warranty on it so I'll talk to them. I got it for $79 so I can't complain much.


For the 270X test rig, it's pretty much the same as all of my others, usually the only difference is PSU. Here it is:

ASRock 970 EX4
2gb DDR ram (Kingston HyperX or Corsair XMMS, whichever is cheaper)
AMD Sempron 145
ADATA 3.0 8gb USB stick

PSU: Thermaltake TPG-1050M

1x PowerColor AXR9 270X 2gb
1x Sapphire Dual-X R9 270X 2gb
3x VisionTek R9 270X 2gb

Software: BAMT 1.2, Cgminer 3.7.2

GPU Settings:

"intensity" : "20,20,20,20,20",
"worksize" : "256",
"kernel" : "scrypt",
"thread-concurrency" : "24000,24000,24000,24000,24000",
"api-port" : "4028",
"expiry" : "120",

"queue" : "1",
"scan-time" : "60",
"scrypt" : true,

You could ignore the redundant intensity/powertune/tc settings, I just left that from when I was doing individual tuning.


Yes indeed! I saw the challenge he put out, I love it. Oh wait, what's this.. I'm ahead? Not for long I bet lol..


No and No. There's stuff I'd love to buy from Newegg right now.. wish I knew a way to go BTC-> Newegg as well. LMK..

As to Amazon's, I talked to a lady the other day from amazon, she said when it shows that it means it's an item they don't often carry high stock on, so when you place your order, they will then order the item from the distributor. My gut feeling was to not even try since the distributor was probably bone dry. I could be wrong, but I just didn't want to tie money up.

As it is I have money tied up with a TOXIC order which is likely never to be fulfilled. At this point I just want to sell the card for a profit to buy more 270x's, but I'll probably just end up cancelling the order if it doesn't ship this week.

The good news is I think a fresh shipment of some cards may be on its way as the factory seemed to have gotten some more 270's in stock..
