Advice? Post by: Noitev on April 12, 2011, 03:53:55 AM I think I thought it out fair, and will use the guiminer for each card. but anything blantantly stupid?
Title: Re: Building computer for mining, bought these. Advice? Post by: allinvain on April 12, 2011, 03:55:06 AM Pretty good..although for a dedicated miner you really do not need a 1 TB hd, unless you plan to use it for some other purpose as well..ie file server?
That Rosewill power supply though, is it reliable and can you trust it with a high end card like the 5870? What do the reviews say? Title: Re: Building computer for mining, bought these. Advice? Post by: Noitev on April 12, 2011, 04:01:28 AM It hadpretty fair reviews. Opted for a 1kw supply since I have the two cards going. The terabyte is for storage as I may use this computer for browsing, etc. probably going to instal a completely legal *coughcough* windows 7 ultimate for minor tasks.
Title: Re: Building computer for mining, bought these. Advice? Post by: nster on April 12, 2011, 04:06:04 AM If this is a dedicated miner, you are paying WAY too much. If not, then it looks good
Title: Re: Building computer for mining, bought these. Advice? Post by: Noitev on April 12, 2011, 04:07:00 AM well its a do everything computer... I may make a dedicated miner eventually, but this is for everything with priority on mining
Title: Re: Building computer for mining, bought these. Advice? Post by: allinvain on April 12, 2011, 04:11:38 AM It hadpretty fair reviews. Opted for a 1kw supply since I have the two cards going. The terabyte is for storage as I may use this computer for browsing, etc. probably going to instal a completely legal *coughcough* windows 7 ultimate for minor tasks. Oh yeah a 1KW power supply will be more than enough. Just remember that if you're going to overclock them your power usage will go up and often it does not increase in a linear fashion - in other words there are diminishing returns. Where have you priced this build? Newegg? Title: Re: Building computer for mining, bought these. Advice? Post by: Noitev on April 12, 2011, 04:12:55 AM WEll i bought all this on newegg already. This is my finished shopping cart. Never built a computer so im trying to have fun with it. Wanted to see if I did anything blatantly dumb, but my friend says it looks fine.
Title: Re: Building computer for mining, bought these. Advice? Post by: nster on April 12, 2011, 04:22:11 AM looks fine.... though next time, if you want a better tweaked build or just want to check, bitcoin.org is NOT the place to go... instead, go to techpowerup.com or similar sites
Title: Re: Building computer for mining, bought these. Advice? Post by: Noitev on April 12, 2011, 04:32:03 AM I thought you would have more experience with the specific info. but meh. How much would a 1ghash dedicated miner cost anyway?
Title: Re: Building computer for mining, bought these. Advice? Post by: nster on April 12, 2011, 04:42:12 AM I thought you would have more experience with the specific info. but meh. How much would a 1ghash dedicated miner cost anyway? depends if you mind buying used etc. A dedicated miner, IMO, should at least have 2* 5970 or 6990s, but IMO, a dedicated miner should be 4* 5970 or 6990 (using linux), as that is what will give the best return on your investment. Dedicated miners are a risky business if you pay for electricity, and even more risky if you pay more than 10cents the KW/h Title: Re: Building computer for mining, bought these. Advice? Post by: dust on April 12, 2011, 03:15:00 PM A good 650w PSU will run 2 5870s at stock clocks and a Sempron. Of course, if you are using a CPU above a Sempron or overclocking you might want to go with 700w or 750w.

Of course, if you are using a CPU above a Sempron or overclocking you might want to go with 700w or 750w. +1 I'm running a pair of 170W cards and an overclocked Core i7 950 on a 700W power supply just fine. Any 1000W power supply that follows the ATX spec will run a pair of 5870s at whatever overclock they can feasibly run at as well as all of the other components in your system, but you would've been fine using an 850W PSU as well. I'm sure that 1000W unit you got will be more than enough. Title: Re: Building computer for mining, bought these. Advice? Post by: sanchaz on April 12, 2011, 04:48:56 PM i'd gone for a 750 or 800+ corsair PSU, imo they're more reliable.

HX1000W is the one I have and it's a beast..it should easily handle two 5970s let alone 5870. HX850 would be a good one. The TX series are excellent as well. But if I'm not mistaken Corsair's power supplies are typically a bit more expensive than the competition. I think the Cooler Master power supply suggested here is a good one too: https://en.bitcoin.it/wiki/Mining_rig $150 is not bad :) Title: Re: Building computer for mining, bought these. Advice? Post by: Noitev on April 13, 2011, 03:41:45 AM well things look good. everything but the cpu, case and a mouse (oh no) are here. installed the ram, waiting patiently...

Post by: phenom on April 13, 2011, 12:06:46 PM You have a lot of unnecessary equipment for a dedicated mining machine imo. Also, when you factor in electricity cost and mining difficulty increasing I'd be interested to know how long it would take for you to eventually generate enough BTC to cover the cost of your equipment. I'd guess 9 months if it's running 24/7.
