On that last picture, if you could mount a fan to blow air out of the case on the grill on top, it would cool it down a lot.
Also, if your PSU is hot, double check the side to make sure there's no minimum for the outgoing power.
Some PSU's need to be letting out a certain amount of power to not fry themselves.
Thanks kain, I checked forthe psu, i don't think so these are some bad ass psu plus with that video card sucking i doubt it has a low power out situation.. but as far as the extra fan.. Interesting idea.. so remove the pipe that leads to the cpu cooling from the side of the computer case and add a fan there that sucks the hot air from the "top" and blows it out ? .. won't that lead to the cpu not able to recycle are well, or even too much air going out (already 1 far + psu up there) and not enough air coming in so possibly creating a stale mate and not really helping? .. god i wish i smoked if toss in some nice cig smoke and record it, slow it down and see the actual air flow  so mounting an extra fan in the BACK of the psu (directly onto it's grill) would prob be a bad idea? |

Hey guys just got a small airflow question. I have cats at home so I have to use a "closed" case and so I'm re-using an old case I had Specs 2g ddr3 kingston (cheaper then buying 1 g) 225 AMD x2 AM3 (long story short 5e more then the 140 so might as wel) G-byte MB 1x 5830 - Slight o/c at 850 runing stable 24+ hours at 62c 525w Bronze 80+ enermax pfc modular power supply My problem is two fold, 1 i notice a few hash rejections (4000 shares submitted 100~ rejected) in a pool, not sure what that means but i dont think it's a problem as even without the o/c and so on it did it anyhow. My real problem is my PSU feels sooo hot and so is the top of the case, i was thinking of adding a fan in the back ONTO the grill of of the PSU sucking the hot air and pushing it out but i was unsure if that would mess up the air flow from the 120' fan it has built in .. the rest of the pc seams pretty cool mb is around 30c' and so on.. .. i've added fotos, if any one has any idea on how to reduce temp to further help + see any out points, let me know.       THANKS SO MUCH for your time and suggestions...  |

ok ragazzi sto minando usando GUIMiner con server solo dopo aver scaricato tutti i blocchi con bitcoin. la velocitą č circa di 315Mhash/s. una domanda ma come faccio poi a sapere quanti bitcoin ho prodotto? dove lo vedo? come prelevo i soldi dopo aver venduto?
ottima domanda... me lo chiedevo anche io, pero per quanto capisco e semplice, essendo che quando fai solo mining il server e il tuo bitcoin, il cui se collegato alla network, se uno di questi giorni davvero scopri un block vedrai nel tuo wallet 50btc, guiminer lo dismostrera anche se solvi un blocco pero tieni presente che con la difficolta attuale e pur essendo che ai un mh/s "carino" le probabilita che ne solvi uno non sono molto alte. |

Something to consider...unless you have an Austrian (real) economic background, you may just think bitcoin will fail or is not a threat. You won't see it as the most magnificently beautiful and elegant monetary solution man has seen thus far. So even though the CIA was given a presented about bitcoin, they probably won't understand the full potential. People in general won't understand the potential either. People will probably come out with conspiracy theories claiming the bitcoin technology was handed down by aliens to save humanity. I guess my point is that most people today can't think rationally, so bitcoin should have some time before governments start going hysterical.
This. I can imagine the FED getting hysterical in the future and i do look forward to it. Ahhh just reminds me of this http://www.youtube.com/watch?v=ZPWH5TlbloUI'm going to pass this vid on for ever, awesome stuff mate, thanks for linking it. |

I'm sorry I must of not been so clear about my question...
Anyhow, I found out that there are no 128 -bit versions of this card, or better none from sapphire. After calling the merchant I had him give me the exact part number, and was able to find it on the sapphire help line and it is indeed a 256bit memory interface card so i bought it (113e). Plenty in stock btw if you live in Europe.
Meanwhile I don't have a good way of testing this, but it would still be nice to know how much the memory interface would affect mining (as in speed loss/gain based on 128 vr 256 bit interface).. i don't see my miner using much memory at all on the card thus I'm thinking it would not as most work is just gpu based but i do see on the forums that tweaking the speed of the memory does make differences so i'm not sure ><
thanks for all that replied btw.

Hey guys,
I have the oddest issue, I've been shopping for a nice ATI card, I've seen a lot of very very good statistics in the hardware forum for the ATI 5830 card. While I started shopping for it though i seam to find 2 different versions.. both with GDDR5 BUT on some sites they say there is a 128 memory interface version and the other 256 bit version.
This is the "supposed" 128 version
SAPPHIRE AMD RADEON HD5830 XTREME PC
● AMD RADEON HD5830 EXTREME
● PCI-E 1GB GDDR5
● HDMI, DVI, D-PORT
and then the 256 bit version
VGA SAPPHIRE ATI PCI-E HD5830 1G GDDR5 D
● ATI PCI-E HD 5830
● 1GB GDDR5
● HDMI, DVI, DISPLY PORT
but on the saphire site, all the 5830 that i find all have 256 bit, i'm wondering if this is a mistake or what it might be as well as, has any one had experience between the two "versions" of the card and will they cause differences in mining speed? I noticed the memory load on my nvidia card is really low during mining so i was not too sure it would make a difference.
Thanks guys

sorry might sound quite "stupid" but as the difficulty scales go up (meaning less bitcoins are generated per mh/s) would it not cause by default, an increase of value of BTC as they become more "rare" or "harder" to "produce"?

IF the retailers realy honour their warranties, why not just buy 2 cheap PSU:s at the same time? It's often cheaper to buy two cheap ones than one really good. When the first of the two gives up, the switch will only take an hour since you already have the replacement in hand. And it doesn't really matter if it takes a week or two to get the faulty PSU replaced.
it's a nice "idea" but keep in mind that it "can" do a blow back and knock out other parts of a pc when a PSU dies. Or even worse it can give sub par power/w to the machine, causing them to fail much faster...  thus why it's worth it to get a nice solid one IMO. |

I tried using search, but I did not quite find the "resolution" to this problem... so i figured I would ask. First of all, thank you so much, as soon as a few bitcoins are in my wallet I will donate for sure... meanwhile though if you have an idea as to what might be causing this I would so appreciate a reply. If i start the latest version of the miner (not the new beta from today but the latest release).. and i set it up to do CUDA mining within my mining group .. i'm getting a nice and constant 45m/s which based on my card (nvidia450gts with slight over clock and no extra "flags" used) i gather is "ok". BUT If i "stop" mining, then use my pc a little (say watch a movie via vlc.. or run a game client) then i close everything and go back to "start mining" it will top out around 19m/s and stay there.. reguardless of what I do. Only way to get it back to the "right" 45~m/s range is to re-start my pc, then it will go at 45 for days with no issues... Any ideas? If you need more info ler me know, but I have win7 installed, latest version whql drivers for the card and .. thats about all i think is important no? Thanks... --- EDIT: I'm including the logs where you can see that right after "starting" and then "stopping" if i start the cuda miner again the video card slows down drastically (about half as fast).
