Title: Need some advice for my first rig Post by: ltcnim on February 05, 2014, 01:24:19 AM hi,
I'm currently planning on buying my first scrypt mining rig, and need some tips with the hardware. so far, I have the following components in mind: ASRock 970 Extreme4, Mainboard AMD Sempron 145 AM3 G.Skill DIMM 4 GB DDR3-1600 3 x SAPPHIRE Radeon HD 7950 OS: BAMT from USB stick alright, and here are my questions: 1. What PSU do I need? would a Xilence Gaming Series 800W PSU be enough for all three cards? Or do I need more? I was also thinking about 2 x 500WATT PSU and use them both with a dual PSU adapter cable. 2. Do I need powered risers? Or can I use normal ones? 3. Does anyone know if I can undervolt those cards with BAMT, and how much? 4. Is 1.8MH/s realistic? Thanks in advance :) Title: Re: Need some advice for my first rig Post by: QNX on February 05, 2014, 01:52:04 AM Quote 1.

I was also thinking about 2 x 500WATT PSU and use them both with a dual PSU adapter cable. it's cheaper to buy two, and you need a simple wire adapter or you can make you own dual psu switchQuote 2. Do I need powered risers? Or can I use normal ones? probably yes, because ASRock 970 Extreme4 don't have additional power for pcieQuote 4. Is 1.8MH/s realistic? yes, but if you don't plan to add more cards, it's better to get 4 or 5 R9 270 with 460-480 khs you'll get more and cheaper |
