Topic: How can I make this RIG more cost/hash efficient? (Read 1236 times)

Don't forget to underclock your memory to between 300-400mhz. You can gain an extra 5-10 Mh/s and the card will run 8-10 degrees cooler.
If you're using guiminer, also remember to use the "-v -w128" modifier to get much better hash rates. Only works with ATI cards though.

Same hashing speed when both at stock, but you can probably OC the sapphire ones better because of their better fan/cooler.

Same card so likely same hash or close to same? I noticed the diamond is about 100 dollars cheaper and actually in stock

They are the same card. However, the main differences between them are:

- Warranties
- Clock speeds (apply only for overclocked versions)
- Coolers

You can do some research and see which one has the best warranty and which one the cools the best.

Anyone know the answer to the diamond vs sapphire hash question?

Build something like this:

- Dont get a case, is a waste
- Get a cheap Mobo if you plan to use single card (no diference i tested this myself), if you are going crossfire buy good PSU and a mobo capable of doing 8x/8x crossfire.
- Since you dont have a case you dont need fans (videocard fans are ok because you dont have a PC case so the card can get fresh air all the time)
- Dont get a dvdRw you dont need it just boot from usb (use linux or instal windows via usb)
- Get the cheapest Hard drive (you dont need a big one anyway)
- Get the best ATI video card you can affort, more than 300-400mh/s. With all the saving doing the things i say above you can get a good card.
- Since you dont have a case you dont need fans (videocard fans are ok because you dont have a case so you can get fresh air all the time).

All the mining rigs i own are like that and all of them are working perfect (9 months no problems so far)

you don't. just use a deskfan.

Hmm...I really dislike the idea of exposed hardware where I want to be keeping these rigs. But I may find a solution. An extra 40 for protected hardware isn't so bad.

Also, do you know if there is a big difference between the m/hash on the diamond and sapphire 5830s??

I'll do it later. You don't really NEED extra fans, unless you want to keep them really cool. The GPUs have fans already mounted, and the cpu heatsink should come with one.

Thanks, someone should make and sticky a thread as anyone interesting in maximizing mining profit will ask this question. Don't need a case, really? Where would I mount the fans then?

OK, you don't need a DVD drive, you don't need a case, you don't need a hdd (you can boot from usb), you only need 1gb ram, and you only need a sempron.

That should save you a bit.

A little help and I'll send a 1/4 of a bitcoin. That's all I've made so far on my terrible mining gpu, gtx 580, but much much better IMO as far as gaming. This is why I need a independent mining rig

Been studying up on the forums, and I found this previously recommended hardware.....on this thread here. http://forum.bitcoin.org/index.php?topic=14166.0

Depending on what you mean by "light gaming" this may work for you and be much cheaper:

Much cheaper, if you think you need more power, substitute the Fusion motherboard for:

I like this list, but even lighter on the gaming if possible, would be preferred if it saves me some cash


Swap out the gpu in this setup for dual 5830s (for $150 you can get a diamond 5830 which seems to average between 250-300 m/hash...or is that the sapphire only? the chart does not specify. https://en.bitcoin.it/wiki/Mining_hardware_comparison#Nvidia) and I think that's a pretty cheap yet efficient rig (anything that can pay itself off in a month is efficiency IMO, I've seen some people pay off in 3 weeks). Is there any improvements I could do here, as far as cost/hash efficiency? I'm open to any suggestions. I'm going to purchase just 1 set of hardware for now to see how I like it, but if its the most cost efficient I'll probably set up a couple others.

Thanks everyone
