Cryptocoin Mining?

[suklee]

At 20 intensity? If so there's something very wrong. If it's at like 12 or something it may be ok for such a low intensity, turn it up if so.

Yeah, tried 13, 15, 20, still not stable at all.

Have you run into this black screen problem? http://www.overclock.net/t/1441349/290-290x-black-screen-poll/360

 

[wand3r3r]

Suklee, I found this to be the best settings for R290s..

Thread Conc: 24440
GPU Threads: 1
Vector: 1
Worksize: 256
Intensity 19 or 20

This yields 836 kH/s at stock R290, for the card with Hynix, and about 818 kH/s for the Elpida card.

Also you may need to increase power tune to 25 or 50% and let it do what it wants to not throttle. Also Elpida vram gets WORSE performance when its OC or underclock, by a massive margin. Damn you Elpida!

I doubt they are universal (TC), the rest are the same as my 290x config. I have 2 290x's and both require completely different thread numbers. I should do more testing but the worse card couldn't handle the higher TC anyway, it would crash.

Dual card configuration
--thread-concurrency 32765,28600

The slower one is confirmed Elpida and requires a lower TC. The faster one (by 100 khash) is suspected to be Hynix but I doubt I'll ever bother checking.


The Stilt is getting a little progress, I am over 900 on one and would like to hit 1 MH/s on it and raise the other from ~830.

https://litecointalk.org/index.php?topic=12830.msg101575#msg101575

Edit: Cranking up powertune to +50 resulted in a slight boost. I was getting ~930 but I believe it's about 945-950 now.

No, I haven't had any black screens. The only issue I've had is when testing mining configurations or in BF4 it's crashed, although it's rare. Actually between afterburner and mining configuration I've had plenty of funkiness, however it's 100% stable when I quit tinkering with it and just use it. When I switch from mining to gaming I've often had to reboot since AB doesn't let you touch the voltage in Crossfire (haven't tried, it's blocked out) so when I quit mining to game I enable crossfire and reboot sometimes.

All I know is that I spent several hours tinkering with cgminer before I got it to work. I don't know what to suggest since it's quite the temperamental piece of software.

I tried downclocking to low speeds like 800/1000 and mining is still crashing on me. Sometimes it's the black screen of death, sometimes the display driver stops & reboots in Windows. Very strange. Still racking my head and trying different settings...

BF4 is still rock solid.

If I'm going to spend another $1000 for another R9 290X under Water is it worth to say an 1800Khz Hash with Litecoin to make $380/mth - Remember my rent don't consider Electrical bill.

Will a XFX Pro 850W KM3 Black Edition BEF handle 2 Ref R9 290X's under water when Crypto Litecoin Mining?

What are your settings and what mining software are you using? I run 2x XFX 290x at 860/1250 and get about 823Kh/s each undervolted.

try
cgminer --scrypt -I 19 -w 256 --thread-concurrency 40200 --lookup-gap 2

$1000 is too much an investment for the hash. Unless you plan on using it for gaming and want full waterblocks, just do a ghetto AIO mod for dirt cheap. It gets the job done for mining loads.

My 850W is fine with both cards mining and CPU compressing a zip file.

So doge

I don't know about the xfx psu, I have an Corsair HX850 with 2 290x's and it's (stock core with +50 power limit and 1500 memory) around 700w. It was under but with the +50 it seems to jump around above and below (it's not a static read, hops around). 850w is fine, depending on the quality of the PSU.

As for the value, paying $1k will take a while to pay off at current rates and who knows if it's going up or down. Sure it will cut part of the cost off the card anyway, but it's up to you to decide if you want to subsidize part of the cost and plan on not being sure if you'll recoup the full cost.

I use cgminer 3.7.2... Tried the above settings, it shows a high hash rate (from 1.0 to as high as 1.7M!) but nothing is ever accepted. I always hard crash when pressing Q to quit cgminer.

According to afterburner, the memory is jumping between 150 and 1250 constantly:

 

[Silverforce11]

So doge

I am happy for Doge..

But so sad for me.

Edit: There is no doubt about it now, Doge is THE THIRD COIN. It's trading volume is matching LTC, in terms of total $/BTC exchanged. It's network hash rate now has spiked up to 1/2 that of LTC.

If any miners missed out when Doge was released, with low diff and earning a million coins or more a day on a single GPU.. well, I see here an opportunity, because it won't be long when you look back and think, you could have mined 20K a day, if only.

[Silverforce11]

Card: REF 290, Elpida
Core: stock 947
Memory: stock 1250
Core voltage: -25mV
Power tune: default
Fan speed: Ghetto Water
Intensity: 20
Thread-concurrency: 24440
Work Size: 256
Vector: 1
GPU Thread: 1

Hash rate: 830 kH/s

The Hynix one, exactly the same settings: 845 kH/s

What I am interested in, is GPU-Z readings if you guys have it, really interested in the Power usage:

This is my Elpida card mining, peak power is about 203W.

 

[Z15CAM]

Thanks Silver

$1000 is too much an investment for the hash.

For another 800Kps Hash perhaps so but lets face it $1000 is the cost for a 290X and WB including 4 more Barbs in a Loop.

Say Hashing Litecoin at 800 Vs 1600Kps.

As far as gaming - YES - I'm interested in 2560 x 1440p CF 290X Mantle BF4 as I already have the WB Platform but then for an additional $1000 - Can I recoup costs within a year through mining Litecoin?

Reminding that electricity is no cost to me and again will a XFX Pro 850W Black Edition BEF handle mining with 2 x's 290X's under water?

 

[Silverforce11]

I just don't see the value.

You could get a reference R290 (non-X) for ~$400 USD (if its near MSRP in Canada, as it is here where I am). A cheap AIO water cooler, $6 VRM heatsinks from ebay, any 120mm fan.. and have yourself an uber quiet and cool miner that pumps out 830 to 845 kH/s at stock settings, or 900+ with a small OC to 1ghz core and vram to 1350 (Hynix is easy, but Elpida is le-shiat).

So for the price of <$1,000 USD, you can have 1.7 Mh/s with 2X R290 Ghetto Cooled.. the way I see it, you cannot beat that value nor the silent operations nor power efficiency for the price.

As to your question about ROI, nobody can be certain, we can only deal with trends. Currently the trend is very good.

Edit: Z15CAM, I dont think it will be an issue with the 850W, under water they consume much less power than running at 90-95C.

What are your settings and what mining software are you using? I run 2x XFX 290x at 860/1250 and get about 823Kh/s each undervolted.

try
cgminer --scrypt -I 19 -w 256 --thread-concurrency 40200 --lookup-gap 2

Using same settings in guiminer allows (so far) stable hashing @810 kh. Right now I'm at 900/1400. Does anyone what 'aux voltage' sets in afterburner? Memory voltage slider is greyed out.

btw, is 8GB system RAM enough? Is getting another 8GB going to help?

 

[taltamir]

So, cudaminer vastly outperforms every other miner on nvidia cards and make them not totally suck (still not a good buy, but you can profit off of your gaming card).

Is there a mantleminer in development?

Heh looks like your rig and mine hates cgminer.. guiminer works good, 810 at 900 core is spot on. You should test the vram, I found it works quite well at stock 1250 for Elpida..

Try undervolting -25 mV and run it at stock 947/1250 (look at my screenshot above for settings), see if its stable. Should use a bit less power and require less fan speed to keep it cool.

 

[Z15CAM]

Silver you're missing the info on my platform. I can run 2 x 290X's through a Koolance 401x2 with one or 2 x's 400-PWB Pumps and a Magicool CG 280x60mm rad but the additional GPU WB cost around $200 by the time I pay Shipping and HST from NCIX.CA + say another $650 for another 290X equaling approx $900 - Are you saying save $100 and buy a 290? For $100, I don't see the point.

My CPU is already under a Corsair AIO H110.

One concern I have is a 850W PSU enough to mine with 2 x's 290X's?

I'm Canadian too ;o)

You are building a gaming rig first and foremost, so sure, go for it since you already have the loop.

I am just seeing it as a mining rig, so to me, hash/$ matters more.

A. You don't pay for electricity and B. You have two very powerful Radeons.. not putting it to mine to pay for itself is silly. If that answers your questions.

One thing I've noticed is after cgminer crashes and/or the display driver restarts due to cgminer, I have to reboot the PC. Otherwise I get really weird hash rates, if any. That actually may be why you got those almost 0 hashes?
