getting into bitcoining?

Litecoin is a ram whore, just watch your VRMs. I'm getting a steady 650 to 670 khash using 13.1 drivers, 1100/1700 at 1095 and 1550 mem voltage. Funny thing is I got better khash by reducing memory voltage but keeping mem speed the same.

Core is 63c and VRM is around 85c

Coinotron is reporting 740 khash for me which is weird.

Where can I check VRM temp? On Trixx/GPU Z/Afterburner I only see core temp.
The wierd thing is although CGMiner reports 680khash Coinotron is only reporting 223.7khash, next refresh 321.6. The highest I've seen coinotron go in the past was like 550. Is it just being reported wrong or is my real rate low due to some errors or something? I'm not seeing much stales. I would slow down my fan and temps if CGMiner is being pushed too hard.

The good response I was getting with cgminer from CMD turned and I actually locked up. But was getting 675 k/hash average and 680 k/hash max. I'll try to turn down the thread count or difficulty and maybe go back to underclocking.

What's your ASIC quality?

You could try both and see if it yields any gains. Otherwise I'd stick with that single quad.

By the way, the Black Ice GTX 480 is a beastly rad. I had one several years ago and it cooled just about anything I threw at it. I eventually migrated to a pair of XSPC RX480's as I wanted to run my fans at a lower RPM - something the Black Ice GTX doesn't perform well at.

Nevermind about the BlackICE, I got the EK quad rad with four 1150RPM Gentle Typhoons. The person I bought it from said that there was no performance difference between using 1150RPM fans versus 1850 RPM fans. I find that odd though, and I don't believe it until I test it. I'll probably not be testing it ever, since I'll be swaping the 1150 typhoons off the EK rad anyways to four 1850 typhoons that I already use on my swiftech triple, and then move those 1150 typhoons to the triple swiftech. I bought 1 extra 1850 for upgrading to quad.

Woke up. Hash was down to 570. Restarted the job an back up to 670. Weird. Any ideas ? I check VRM temps with gpuz and am using reaper, not cgminer.
 
I have found cgminer to be superior to reaper so far. Reaper may be based on older architecture.

How do you check VRM temp in GPU-Z? Is that the same as GPU temp? Only temp I see.

I'm having problems as well, I haven't got 24/7 stable. I can run cgminer up to 670-80 khash for hours at 80C. Then when I go to bed and leave it on overnight I wake up to see PC on but screen won't turn on, restart and see windows reports bluescreen error. So I guess I haven't got 24/7 stable yet. My card has voltage issues with low ASIC (57.1%) maybe that's the cause. I don't know whether I should underclock or overclock. My normal OC is solid for gaming and normal usage. I'm getting 2 Noctua 140mm Variable Impeller Fan with Vortex Control to replace fans on my H70, and replace a rumbling top vent 140mm fan and install extra fans perhaps for cooling.

Also in MSI Afterburner, I can't raise memory clock higher then 1575. It is the only software though that I can find to change memory voltage down to 1550 etc. Trixx I can go higher on memory clock but no way to adjust memory voltage, just core voltage option. If I setup OC in trixx with 1700 memory / 6800* , then open afterburner it shows up as 1700.. but it says core voltage 1125 vs 1250 on Trixx. Any idea why?

Shits crashing


I saw that it jumped to $260 and then prices immediately plummeted back to yesterday's average of $230, saw a long candle wick on the daily candle chart and placed an order on physical goods. Special cookies :)

Servers have been getting hammered for the past few days, bitcoincharts, bigcointalk forum are timing out constantly.

I still have a little bit of rewards on slush's pool and the piece of shit hasn't sent me funds over the last couple days. Things are getting hammered so hard that you can't even get your own coins out.

This reminds me of the stock market crash in 2008 when the exchanges got so jammed up that orders couldn't execute and people got stuck in plummeting long positions.
 
Both ltc and btc are sinking fast on btc-e, I wonder whats driving the sudden, massive exodus.
 
Peeps be cashing out.

10 bucks says the wall street people have hedged their btc shares on the price of a stable commodity...

Mining sure feels like daytrading these days ;)

Probably the dump phase of the classic pump and dump. It looks like the financial sharks began their shenanigans in late January. Just look at a few charts; before and after late January is like a night and day change. $13 to $266 in four months? Taking less than a week to double before the crash? Shenanigans.

Glad I sold a bunch of coins at 220....
 
I fully expect it to jump back up. There is no ceiling on bitcoin prices.

With one, maybe 2 7950s. How many coins can i expect to recieve each month.

Also can anyone point me to where i can get started making coins. Thanks

and how long would you say it would take to make money to buy a P9X79 Deluxe(380 bucks or so)

If you are wanting to do some mining of some sort with graphics cards, I recommend getting into Litecoin, much more effecient then mining bitcoin these days. You can always trade your litecoins to bitcoin if you want to, I have two 6970's and would make less then a single bitcoin per month. However if I mine litecoin and then trade to bitcoin I can make 1.3 bitcoins... that or sell your litecoin for $4.50 per coin.

Like other people say ASIC mining is close, and once that happens graphics cards just wont cut it anymore. If you want to do some asic mining of your own www.butterflylabs.com is your place to go. Just be sure to read the forums before you buy there is a lot of delays and failed promises at the moment.
 
price is half of what it was around 130 last i checked
 
It looks like things are starting to reverse a little bit. I'm not sure how long the buying will last for, but its probably setting up for another round of pump and dump in the next few days... They'll keep doing it until volume runs dry from a lack of panic sellers/impulsive buyers, and hopefully the action flattens out and prices hold just above $100 for a long time after this mess. I'd really hate to continue mining if shit were back at $30, even $70. I won't even want to install this quad rad if this becomes the case. I'll lose all motivation.
 
Shit got crazy today on btc-e trading. I didn't make it in at the bottom of the canyon and I didn't hold long enough but I still managed to make a 10 dollar profit on small quantities...so im happy...now if my rig would just work at 100%...
 
I can't seem to find alot of information on LTC mining. Driving me nutts because I want to mine but info seems to be alot harder to come across than BTC info. I currently do ~1 BTC every 3 days but am wondering how I would fair up vs LTC
 
dustcoin.com to find profitability. LTC mining rates are basically 1000 times less than btc mining....so if you do a GH btc, youll do a MH ltc. allchains.info for estimated difficulty changes and btc-e.com for your trading desires. I also use GUIMiner Scrypt for ltc mining, but if you are more comfortable with using command line, you can use cgminer or reaper.
 
$170, nice recovery, nice swings. Lots of profitable opportunities. I finally got my .07 BTC from slush's poll. Fuck that place.

What wallet do you need to use to play Satoshi Dice? Anyone have anything to say about it? It seems to be popular, but I sent in a test transaction of 0.001, and got nothing back (was not a bet), which means my wallet can't receive from the same address it sends from...
 
I just got my 2nd XFX 7950 and it comes voltage locked. I have a feeling that's why its running so much hotter than my original voltage unlocked XFX 7950 that I bought a year or so ago. Is there an easy/cheap way to quiet both cards' fans down and bring the temps down too?
 
Looks good to me. Lots of media attention, lots of awareness. Prices go back to normal.

for LTC, the difficulty could double and the price could drop to $0.50 per and it would still be profitable for me.
I have cheap electricity. $1 per LTC and I would be happy.
 
When I get home I'll put up a screenshot, but I've notices 2 odd things.

1. My 7850 @ 1ghz core is preforming ~25% faster than my 6950 (unlocked and OC'd to 6970 spec)
2. I'm getting what I assume is a lot of HW (Hardware) errors reported.

Combined I have ~650-700K/hash

I'm using CGMiner. I've looked at the switches to dictate the number of shaders and threads to use, but I can't figure out how to make one setting for one card, and another for the second.

EDIT: I'm MOST kicking myself for not getting into this sooner. Not only-pre bubble and pre-higher-difficulty, but it would have been an excellent way to burn power in the winter and supplement the house heating and not be fighting against the HVAC!
 
This time i'm gonna mine LTCs and hold them for the long term.

When LTCs rear up in 4 years and hit like BTC did, i'll have a mountain of LTCs to sell.
 
Is there any point in trying to do LTC coins on an OC'ed gtx 670?

I see little talk about nvidia cards...

Also, any tips on finding a good pool?
 
I've heard its because Nvidia's cards have fewer shader units. Even though they are more efficient and make up for it in gaming, they can't keep up with AMD's higher count.

What does this mean?
I have recieved .92 and .98 LTC so far. The second transaction mentions 800+ LTC? and 1.8 LTC?
My total payout on coinotron says 2.10 but my wallet says 1.9, I guess the difference is fees?

I've been using coinotron and they are one of the best pools for LTC. I'm using round based PPS.

I'm having stability issues with my 7900. At 1135/6800 @ 1.25vdc I get best performance 680 k/hash running cgminer (20intensity, 16GB thread) Do I need to add anything about shaders?

Here's my max cgminer script
Code: 
-p x -d 0 -w 256 -v 1 -I 20 -g 1 -l 1 --thread-concurrency 16384  --failover-only
It will run for hours and average 80-85C but if left overnight it gets up to 90C+ and usually freezes.
My 7950 can't run less then 1.2vdc even that crashes it sometimes, I don't know if I'm locked around 1.25VDC or if my low ASIC 57.1% is the cause.

I made a cgminer-low script so I can still use PC. Right now its running at 375 k/hash with full PC responsiveness. Right now I'm clocked at 1200/6000 on Trixx, 71C temp, rock solid
Code here->
Code: 
-p x -d 0 -w 256 -v 1 -I 14 -g 1 -l 1 --thread-concurrency 8192 --failover-only

My question is what further optimizations can I do? Afterburner won't show higher then 1575 memory unless I set higher clock in Trixx first, exit, open afterburner, it always resets to max 1575 on afterburner, and if I drop mem volts to 1550, lower core volts to 1125-1200, lower or raise memory clock, it doesn't reduce temps at all and becomes more unstable. I'd prefer to use Afterburner for its graphs and tray temp but its not as reliable as Trixx for some reason.

Can i adjust shaders in my code? What can I do to get a better Max / Low scripts at more stable temps? I love seeing 600 khash+ but so far PC usually becomes unusable for basic usage and after hours of mining usually fails probably from slowly ramping up heat. I hear that 80-90C is ok for these cards, but I thought my 7950 dual-x boost cooler would do better. I've put some more fans in my case to try and aid the GPU cooling, not sure if this will help.

After getting some new fans in the case positioned properly I haven't seen temps past 85C @ 670/khash. PC is also mostly usable so far. 1250coreV/1550memV/1135/1700 clocks
 
Has anyone got any brilliant ideas on keeping a mining rig in Texas come summertime?
