I just saw that our manipulator is back buying 50k coins at $2.30 a piece of MtGox. Does this mean we have seen the last of this bear market? I think he figures he manipulated the market as low as it will go in one day. Quite the profits for him. Based on what I see over the last month we could see a rally to $3.50 in the next couple of days.

Whats everyone elses thoughts on this?

I still had the cover on my case but I do not think it was from anything overheating. My gpu and cpu were at full load and its 5 or 6 year old power supply. I never had both at full load but it was likely drawing somewhere near 600W and i suspect that it just crapped out. It can happen and the main thing with power supplies to see if they can run your gpus is to look at how much current is on the 12V rail (mine had 2 x 12 V 18A rails).

Edit

Thankfully it was only the power supply. Have since installed an Antec HCP 850 and an additional 140mm case fan. Idle speeds have dropped 10C and everything else appears to be in good shape... phew!

FML something just fried and good. There was a loud pop then it shutdown (probably a capacitor). I waited several minutes and tried to restart (2 more loud pops). My motherboard is rated for mil spec and has a 5 year warranty. There is also the clear smell of burnt electronics. Either my GFX card or power supply went I figure. I am hoping it was only power supply as i have been thinking of upgrading and its 5 years old or so. Either way this really sucks. A risk you take when overclocking.

Update

Just did the sniff test. I believe its the power supply. I removed the card and there were no signs of the smell of burnt electronics. Someone at work luckily just bought a 750 or 850W modular power supply and is selling it for 30 less than he paid. There are no signs of burning around the cpu and I am extra glad i got a mobo with surge protection. I just hope I didnt fry all my hard drives lol. Also the smell from the psu smells like burnt electronics furhter leading me to believe my 600watt psu finally gave up.

f1 is the only one I can connect to. pit.deepbit.net:8332 will not connect for me but f1 seems to every time.

On a positive note I seem to have optimized my mining. I have my cpu worker set to 5 threads using ufasoft miner at about 18Mhash/s and about 373 Mhash/s using phoenix miner for my gpu with vectoring. This puts me around 391 Mhash/s while I was getting about 383 with polcbm in guiminer. Thanks for the help.

Edit

I can really feel the heat pumping out of my case now. I guess my apartment wont be so cold this winter lol. Kind of makes me want to take it out of the desk though.

Hmm interest so I set the server to f1.deepbit.net and I got a connection right away this time. I am mining at 20.3 Mhash/s with my CPU now which is almost as much as the GTS 250 I just replaced from this computer. Sweetness lol.

Update

Ah crap spoke too soon, the increased CPU load forced my Guiminer to drop to 100-150 becasue there is not enough CPU speed available enough to request data. Going to set it to 5 cores.

Update 2

So with 5 cores I am getting about 17.4 from Ufasoft. Might have to run both with ufasoft to make it more efficient as my guiminer is dropping with ufasoft miner enabled but at times it will run full speed.

Update 3

I just noticed I have GUIminer set at 6 cores and I think it is being about as optimal as can be. I am going to try ufasoft miner with one worker for cpu and one for gpu overnight and see how that goes. I see -v flag specifies verbose output but this flag is for vectors on other miners. Is that what they mean by verbose? Everyting I do seems to indicate about the same performance as I was getting on guiminer.

As I mentioned earlier since I am in Canada and we do not have net neutrailty I believe for whatever reason Rogers DPI boxes are dropping my requests for work from deepbit. I am sure my command line is correct now

bitcoin-miner.exe -u username -p password -o http:\\pit.deepbit.net:8332 -g no -t 6

Guiminer usually takes several attempts to connect before it can successfully. The retry interval for Ufasoft appears to be set about 30 seconds and for guiminer (polcbm only) its about 5 seconds and it alternates servers. If I could increase the retry attempt to 5 seconds I might have some more luck but I did not see a flag for that. Thanks for the help though.

Edit

Wait is it -a? I think im going to try setting that to a lower number than the default 15

Well I hope the GPU isnt damaged but I guess thats a risk when you buy it used. I am trying to run UFAsoft with 6 cpu threads right now. After leaving it running for a minute I see my problem before was that it was not connecting. "Error 80072EFD: A connection with the server could not be established". I will see if it connects soon and if it does I will update this post with what I am getting

This was at the stock settings and nothing tweaked at that point. It does not happen with other miners really too. polcbm has since jumped up to a stable 383 Mhash/s. My motherboard has 10 phase VRM and in theory should be great for overclocking (Sabertooth 990FX). I suspect that was likely due to a lack or work available from the server and Guiminer has comparable performance. I launched GUIminer right after and got the expected performance numbers immediately. I did buy the card secondhand though and I suspect the previous owner used it for bitcoin mining when prices were higher (card was originally bought June 9th). My CPU never goes full load but if I could mine that at 100% in addition to the GPU it would be nice. I have a 1090T 6 core processor running at a stable OC of 3.6Ghz/core with a Corsair A50 and it has a hard time ever breaking 50C, even with prime95. I figure that this cpu should be good for a few Mhash. Please note electricity costs are irrelevant to me as I live in an apartment and my landlord is an a-hole who charges more to me than new tenants.

I live in an apartment so I do not pay for electricity. The landlord recently decided to jack my rent up $50 instead of the $8 that would normally be allowed so I have no qualms about using extra electricity. My only concern would be overloading my 600W power supply.

Update

Some famous last words. It died last night in violent popping death. Was planning on buying a new one anyways

I tried CGminer too but even at my lower clock speeds it would run great at first and then the performance would drop by about 50% after 10 minutes or so. Someone told me it was the most efficient but so far I am finding the most efficient for my card appears to be phoenix with settings someone else provided for me but as I said I cannot connect to deepbit with that. I do not know the programmer personally and OC issues are the main suspect to the crash I had but I am hoping thats not the issue. Its about as fast as I can push it without the catalyst drivers crashing on me. My card is a 6950 and Im running it at 1.2V (1.1V stock), 955Mhz Core, 400Mhz Memory (Underclcoked by 900Mhz) and a custom fan profile that keeps it runnign around 80C under full load. I lowered it from 959 to 955 after the crash and if it happens again I will try 900. The joys of finding a stable OC lol.

Its also good to know about the temp monitoring thing. Asus AI Suit loads at startup for me (I cant find the service to disable), I had HWMonitor running (becuase it shows max temps) and I had MSI Afterburner running (to get the required clocks and fan profile) so I technically had 3 running. I will try to avoid doing this from now on.

My comptuer crashed while running the DNSBenchmark but it could have been duie to my OC settings. I have since been able to connect with GUIMiner to deepbit. There were some servers I saw that DNS Benchmark was unable to connect to and I am hoping that the crash was due to poor coding of the program and not the OC of my card. I will run overnight to confirm. At least I am mining for deepbit again. Deepbit speeds are about 374 compared to 388 but that is probably just the innefficiency of polcbm over phoenix. Its livable though considering without any flags and at default clocks I was getting 300.

I am in Canada and on a third party ISP on a rogers network. They are known to do traffic shaping (rogers) which could be causing dropped packets. I am not using my connection for anything else but mining at the moment so there should not be any packets dropped. Rogers recently got in trouble for traffic shaping WOW and other games so this would not be a complete suprise to me. What is surprising is that it seems to be affecting deepbit only. I have been trying to connect for almost 2 hours to no avail. With Slush's pool most of the blocks I am mining don;t seem to mature so I have next to 0 BTC despite thousands of shares. ABCPool sounds like its similar to deepbit with the proportional mining and payment despite unmatured blocks but their registration is closed ATM. I will try that dnsbench and see if I can find anything.

pit.deepbit.net I am getting 53ms constant through multiple ping commands (groups of 3)
f1.deepbit.net I get 52ms constantly
f2.deepbit.net could not connect a few times but the ping to that is out of whack.

Should I change my DNS from my ISPs to google? I have had some issues with connecting to some sites before using my ISPs DNS but I am not sure if I want google knowing and storing every web page and connection I make. I have been trying to connect to deepbit for the last 50 minutes with no success. Shame too since I boosted my mining speed from 340 to 389 Mhash/s.

The other pools are Slush's pool and bitcoinpool. I mainly mine on Slushs but I find the rewards are much less than deepbit on average. As far as I know they use the same port however.

Edit

Just tried Ufasoft and since the login for deepbit is your email (with @) I think it is confusing my email with the server address and I am getting 0 Mhash. So much for that idea.

The card is non-reference design and I heard the ones that could be flashed have a bios switch which I was unable to locate. I tried running the mem clock as low as 300 but at 400 I can push about an extra 2 Mhash out of the card. I let the card run for about 20 minutes at each setting keeping a running average of the hash speeds. This is how I discovered that anything above this caused crashes anywhere from 2-10 minutes after running at full load. I have not tried unlocking the extra shaders but I did have it running briefly at 407 Mhash/s then crash. The fan profile I have created helps to keep the thermals down. Whats interesting is that even though afterburner says the voltage is at 1.2V HWMonitor is still saying 1.10V. My power supply might not handle a 6970 too well because its a 600W thermaltake with 36A on 2 12V rails. This makes me think that I am probably pushing the max safe Mhash/s out of my card.

Thanks again for the suggestions.


Update

So after several hours of mining I had a black screen crash. This was either due to the mining or poor coding of a DNS analysis tool I was running. Going to run these settings overnight and see if it happens again.

I seem to always have a heck of a time trying to connect to the deepbit mining pool. It usually takes anywhere from 10-25 minutes to be able to connect and I have had 0 success with phoenix miner (using guiminer). polcbm seems to attempt to connect more often and thats the only one I have had any success with. Any other pool I connect immediately but I would prefer to mine with deepbit due to the way their reward system works. Does everyone have this problem and does anyone have any suggestions on how to fix this other than mining at another pool?

Alright so against my better judgement as per my last post I tweaked the card some more to see what I could get out of it. I significantly improved performance but also hit some limits. It seems anything above 960Mhz causes the ATI drivers to crash after a few minutes of mining. The memory speed has a small effect on mining speed but it does seem to make a difference. The "sweet spot" I have been running in now is:

Core Voltage - 1.2 V (+0.1V)
Core Clock - 957Mhz
Memory Clock - 400 Mhz
Fan 80%
Temp 81C
Mining Speed 389

This appears to be stable but I am worried about the speed drop. Can anyone comment on whether or not this will be safe for long term use?

Edit

Found how to program the fan profile which is very nice. I have it configured to run 80% at 80C, 90% at 90C and 100% at 100C (hope I never hit that). This makes me feel a little bit better than a fixed fan speed which could potentially allow overheating. I also disabled ATI overdrive which other threads have suggested to prevent the risk of it interfering.

Thanks again for the help. I was considering uninstalling MSI afterburner but will try running at 880Mhz core and 500Mhz ram speed now. I can try running lower settings but I think it should be alright with those. I will let you know the new hash speed in an update to this post.

Update

Memory clock will not go below 650 and set core to 881 without chaning stock voltage. I am mining at 360Mhash/s now = w00t. Was running at 84C on average but am getting 81-82C with these settings which is acceptable for this card I read. I could crank the fan up Im sure by changing the profile but this is acceptable from what I have read.

Thanks everyone

Update 2

83C at 899Mhz core clock. 368 Mhash/s. Not sure I want to push it a whole lot faster than that because I do want to use this card for gaming lol. If someone can verify that they have been running faster settings on a 6950 of comparible specs (see above) for the last 6 months I will try that. I read that someone else could only push theirs to 880Mhz so I am grateful to get ~900

Of course you would like us to stop pointing out the flaws in your scam. Of course you would be glad if we believed you so that more suckers would send you money that you are going to run away with. Like the person above me says, provide proof that can be independently verified. Until then you are a liar.

Least unique light source.... hahahaha.

Actually the sun is the most unique light source seeing as there is only one but thats not all I work with. I work with halogens, LEDs (built a custom 150W LED lamp myself), arc lamps, metal halides and high pressure sodium bulbs. If you are working on electronics then you are going to want a bright light, especially if you don't see too well (the glasses). That in itself is not unbelievable. You really are naive if you think someone that tests and certifies solar panels is only going to use the sun as a source of light.

Edit

Forgot to add custom UV lighting too. Built a custom 2kW UV setup just this week. Point is that I know a lot about unique light sources.

You are not necessarily disagreeing with me as I said some of the shadows would have to be caused by light sources around desk height.

I know there is more than one light source and I fully understand the implications. I work with SOLAR PANELS and deal with some very unique light sources myself. I am saying that the shadows on the two boards she is supposedly working on still do not add up. And yes I have dealt with multiple light sources and do on a regular basis. Specifically the shadows I mentioned are unlikely to occur given the arrangement of lights shown in the photo. and would require certain lighting conditions.

Again even if the picture was unaltered the boards could be dummy boards but I admit that they do appear similar to the other pictures listed in thius forum and on the website. This lends some apparent credibility to their case but if you were running a scam would you release any photo that would discredit you? No. If the photo appears legit to you its because it's supposed to.

If they grant a tour and testing session to the user across the road from their so called office in the welfare lofts then I might give them more credit but they have yet to do so.
