Topic: [ANN][TAG] TAGMining.Com is now the official pool of Tagcoin! - page 3. (Read 45653 times)

Just in time to get my second rig.

I can vouch that TAGMining will be back... bigger and better... but not until a key issue is resolved with accounting code in MPOS.

Fuse and Vesper are working tirelessly to work out and resolve this problem... they have both been putting some very late nights... going through the MPOS code line by line and running simulations on private pools which I am part of... we are getting there... slowly but surely.

^Yeah, what those guys said! 

Pool will open back up soon.  Vesper and I, mostly Vesper in his honestly infinite wisdom, have been tracking stuff down and looking at how things work.  Hopefully, with his help, I can mitigate what was going on before.

Maybe this weekend, but don't hold me to it.

Looking forward to Fuse opening up the pool back up and working some kind of magic to mitigate the orphans.

That's cool opportunity to try your own skills and be rewarded for finding that 20 blocks! Good luck for everyone who are in

I'm confident it will be coming back online very soon, and that it will be bigger and better than before. There's work underway to ensure the orphans and other small technical issues, are mitigated and no longer an issue (which was the cause of the original shutdown). The issues weren't related to the pool but to the coin network, and it looks like the storm is passing.

There's more exciting news I'd like to say, but all I can share now is to stay tuned to this thread.

Crank it back up. Need a good pool to get my TAG position back.

Op, are you going to turn this pool on again? Need to get some TAG. I've got enough POT for now. (well, you can never really get enough.)

Left side is 5 second running average. Right side is average over a longer period of time (could be all-time since you started cgminer).

Both numbers should be close. If the left side is too low, something is wrong or your GPU went SICK or DEAD, and you may need to restart. The right side takes some time to adjust since it's the average hash rate of all time.

this may be a dumb question but my figures i see on screen fluctuate alot while i'm watching

when looking at for the hash rate my cards produce and I see    705.2K/710.8Kh/s  I am assuming its the rights side figure thats important the 710.8kh/s

Because sometimes the left side is higher and sometimes the right side figure is higher but it never stays around 1 figure for long enough for me to decide what i'm getting

Using VBE7 I only get a drop down menu to choose new figures from


1275, 1256, 1250, 1225, 1200, 1188, 1175, 1163, 1150, 1131, 1120, 1100 an so forth.

 With TRIXX I can adjust it down by 1 unit.... not sure how 0.05 and 0.1 relates to these figures.  Later tonight I was just going to play around with VBE7 and the figures above increaseing to the next option higher on card 1 till it is stable

My cards are all the same model all Sapphire R9 280X DUAL-X OC version with the same sku and PN numbers on the label

It's basically finding an equillibrium between efficiency and stability, reducing the voltage the card needs to lower heat and sometimes increase or decreash hash in a stable fashion. You typically do it in slight increments per card to see what works best.


I don't undervolt but I understand it. Every card is different just because of component variance, even if you buy 10 of the same model/brand. Generally speaking same-model cards should have the same default operating voltages, so if you have 2 cards which have different "stock" voltages, make sure they're actually the same model.

Yes, you can undervolt too much and cause an issue. You typically want to do it in increments. Lots of people go in steps of .05, sometimes .1

Well I am no planning to attach a fan to the wall above pointing into the case, and leaving all the panels off. testing it i.e. holding it above the rig, seems to keep temps to the 70s C. some progress there and might enable me to leave the cards where they are.  I haven't decided if I can actually find a way of taking the middle card out and suspending it some how with risers.

I reduced the VDDC to 1100 on all 3 cards using VBE7, the 1131 cryptobadger suggested for his 280x cards wasn't an option on the drop down menu.  Now does anyone have some understanding off undervolting?  I've never tried it before.  My orginal VDDCs for each card were 1175/1225/1175.  I set them all at 1100 and at one point I was getting 710/724/724.. though it fluctuates.  Then card 1 started getting 800+  like this

http://prntscr.com/2ti12h

which as much as I wish I could get that stably I doubt thats right and the screen crashes and windows recovers from a driver failure with sgminer saying something about card 1 having a problem and can't be restarted.  Does it stand to reason that as it already had a VDDC that was higher than the other 2 cards (no idea why they are all the same card bought at the same time) I've set the VDDC too low on that particular card?  I'm going to try chaning the bios again tomorrow i think because the 1100 VDDC on that card clearly doesn't work.  Also has anyone set a VDDC lower than 110 on a 280x card. Or is it a case or changing it around untill the driver doesn't crash?

@FortuneSeeker, I've had good experience with Litecoin BAMT. Grab 1.3 (or 1.5, or both), write it to your USB flash drive, and boot.

Then just get it's ip address on your network, and SSH to it using PuTTy (windows). Edit /etc/bamt/cgminer.conf and put in your own pool details, delete everything else, you can fine tune it later.

Reboot. Watch it mine for a few minutes.

Yeah they're pretty close. If you didn't mind not being able to close the case, you could get some risers and move them up and away from each other and lower the temps naturally. I'm not familiar with how sgminer handles kernels, but here's a link of the official modified kernels, which includes announcement sublinks to the various forums for each which describes how to properly use them (as each one is for different driver versions): https://github.com/veox/sgminer/blob/master/doc/KERNEL.md

If this was a dedicated system solely for mining, I would personally suggest a linux-based approach for stability and higher output, but if this is your personal system I can understand wanting Windows.

Yes I have and it got it working. I was just removing things and trying it and removing the kernel bit did the trick,  So now i'm wondering if I delete all the other .cl files and just leave the optomised .cl file that i downloaded for my card in the kernel directory

 I also have to flash the bios on the cards yet.  but I was getting 2 cards at about 707kh/s and 1 at 680 kh/s, this is an improvement on the cgminer results.  temps are about 70/81/78 but as you can see from the picture cards 2 + 3 are very close together.  I found a fan I can attach to the wall (box fan) which seems to get the temps i mentioned rather than a pc smouldering 90C so I'm hoping with the undervolting the temps will be more stable and I can start fine tuning the settings

I presume you're running windows. What version? Have you tried removing the kernel info from the commandline and then run sgminer?

I've been keeping temps below 75 C. But it should run fine even if it went to 85 C right? Fans are at 80%. Running it at 1125 Engine, 1500 Memory.

I haven't had the chance to undervolt it, I might need to install windows to do that, or plug the cards to another system, but I could also just leave it alone for now. It's not broke, so  ... ...

Thanks for the tips Vesper!

I think I may end up doing a 4x 280x (3 on the 1200w and on the 650w 1 card/system)

With that set up I may be able to squeeze one or two more 270x's or undervolted 7950's on there but I will most likely just play it safe.

EDIT: Was able to pick up 2 Gigabyte 270x for $210 at microcenter. 270's were $199.99 so I said what the hell haha. Can only get them up to around 470 kh/s though. Was hoping for 10-15 more then that but I am satisfied  

If you play it safe, figure 350watts per card. That's 2100 watts, not counting about 100 for the system itself. You'd be looking at two 1,200w PSU's. It's overkill and inefficient IMO, unless there were other reasons for the 280's (such as availability or a great price).

If you get 6 Sapphire Toxic 280X's, the finest 280X I've personally seen yet, and you push it to its limits, you could expect 4800kh/sec, and you'll be at the limit of 2400 watts of PSU.

If you get 10 MSI 270 (or 270X, they hash the same), you would hash at 4900kh/sec, at around 1900w total. This would still require 2 PSU's and would be split up into 2 systems of course. But you can see the benefit of this setup vice a 280 setup.

If I could, I would switch out my 280 collection for MSI 270's in a heartbeat and save wattage.


Yeah, I must have been thinking about the 79xx series or maybe underclocked 280X's. Looking back on my notes, my 280X's draw 340-380 watts each, depending on which one it is. Power-wise here's what I've personally noticed, real-world mining power usage per GPU/model:

79xx: 270-275
280X: 340-380
270X: 175
270: 167-175



Usually it's heat-related, keep an eye out on the temps. Also make sure your power connections are solid.
