Leme tell you a little story about ultracoin!

[torin3]

I have a 7770 with a mild OC, there probably isn't any point, but would it be worthwhile to mine this (or any other) type of coin, or should I upgrade in order to try and do that. Also can this coin be CPU-mined or is that also a complete waste? Sorry about the n00b questions, I know enough to be dangerous about mining in the first place.

According to this post/database: http://www.overclockers.com/forums/showthread.php?t=741513

Your 7770 should do around 200 Kh/s, though given that a 5770 does better than the 7770, I think the 7770 in that list might be having other issues. The auto-trading pools do about .01 BTC per day per 1 Mh/s.

This thread: http://www.overclockers.com/forums/showthread.php?t=743399 shows which are the best coins to mine. It looks like Ultracoin isn't doing better than the auto-trading pools anymore.

200 Kh/s should get you .002 BTC per day. So, at current rates, just over $1 USD a day.

$1/day and then my electric costs $.06 KWh and I pull just under 400W at maximum load according to the kill-a-watt...

So I'd make about 40 cents per day.

nfactor change again? hashrate dropped down by half again on my cards.

 

[bigup]

yep, nfactor kicked in y0

this should get you 150 hash on a 280x

--thread-concurrency 16384 -g 2 -w 128 -I 12

Well, got my UTC outta crypto-trade, but my BTC is stuck there, its below the 0.01 min

UTC still worth mining? I'm on wafflepool right now. Wondering if I should switch.

EDIT: what? Now I'm getting tons of HW errors on the same settings??

 

[bigup]

SP, look above mate for the new settings for UTC

I currently have my hash rate split between the two. UTC is currently at a point where you don't want to sell. As miners get their UTC off of CT, the price will drop down heavily on the other exchanges and then rebound in time. I recommend holding your UTC until after the recovery after the dip occurs.

[torin3]

Bitcoins showed up from crypto-trade about 10 minutes ago.

 

[Janus67]

I'm currently still split between UTC and vert. UTC dropping a lot in value. Dark looks to have risen a bit.

 

[Silver_Pharaoh]

This is ridiculous.

HW errors everywhere, even using --lookup-gap 4. If tuning my 6850 is this bad, I can only imagine what the 270x tuning is like.

I'm done with UTC for now. Until someone makes a guide on re-tuning mining settings.

 

[Janus67]

People have posted working 270x settings in the btctalk thread. I have my 7950 running at 110 and 290 at 150

Thanks! I'll have to look around then.

Still gotta figure out what to do with the 6850



EDIT: Okay, the 270x is up to 80Kh, but the 6850 is dead in the water. Not even lookup gap 4 can help it. Looks like UTC on the 270x and waffle (maybe VTC?) on the 6850.

What are you using? I'm using ultracoinminer on 3 270x's and getting this:

Whoops forgot batch

ultracoinminer -o stratum+tcp://poolinfo -u xxx - p xxx --scrypt-jane --sj-nfmin4 --sj-nfmax 30 --sj-time 1388361600 -w 512 --thread-concurrency 8192 -g 1

if I add -I and anything then the display driver crashes and then the other two run at 91+ Kh/s

My clocks *were* something like 1150 or 1120 core 1500 mem, I can't run my full overclock of 1220 core on UTC anymore..

But that got me 80 Kh.


I basically added --lookup-gap 3 to my old bat file.

Ah HA! It was the intensity, -I 16 is the sweet spot, I tried 19,18 and 17 they all crashed, but poof 16 works great thanks!

Is now getting me the following:

Glad you got it working.

I'm thoroughly done with UTC. Even using our settings with stock clocks produces HW errors within seconds.

If I want UTC I will buy it. (like I have already done)

Might mine PTS since I'd like to hold at least 10 PTS just in case.

 

[zizux]

I started doing UTC just to see how it would compare, I think I'm going to stick with PTS on the rest of my boxes. Probably switch this one back over too.

On lower intensity I get less hardware errors. Still it is annoying.

Yeah, but I just found this little gem: -w 256 --thread-concurrency 24576 -I 15

Using that, no HW errors so far and I get 95Kh with my max overclock.....

Might mine UTC becasue I know the price will recover.
But I'd still like to mine PTS....

EDIT: No. Fu*k this. Now I get HW errors. I'm boycotting this coin. I'm sick and tired of restarting when cgminer locks my cards up. I'm done.

Add some good configs in the comments, and I'll edit the post accordingly!

i get 180kh/s off the 7970/290x config @ now 1200/1850 "core/mem"

and 195Kh/s with the 290/x config. @ 1075/1400 "core/mem"
