Since I haven’t decide to either mine bitcoin or litecoin, I am upgrading my existing system that can do one or the other.
My existing system has been running well for over 3 years. Now is an opportune time to put it to good use. The only hardware I’m replacing is of course the graphics card.
Hardware under the hood now:
- ASUS P6X58D-E LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
- 5 x SAMSUNG Spinpoint F3 ST1000DM005/HD103SJ 1TB 7200 RPM SATA 3.0Gb/s 3.5″ Internal Hard Drive
- ASUS CuCore Series EAH5770 CuCore/2DI/1GD5 Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready
- OCZ Agility 2 OCZSSD2-2AGTE60G 2.5″ 60GB SATA II MLC Internal Solid State Drive (SSD)
- COOLER MASTER HAF 932 Advanced RC-932-KKN5-GP Steel ATX Full Tower Computer Case
- Intel Core i7-930 Bloomfield 2.8GHz LGA 1366 130W Quad-Core Desktop Processor BX80601930
- COOLER MASTER GX Series RS750-ACAAD3-US 750W ATX12V v2.31 SLI Ready 80 PLUS BRONZE Certified Active PFC Power Supply
- HighPoint RocketRAID 2640X4 PCI-Express x4 Four-Port SATA and SAS RAID Controller Card
- CORSAIR CMXAF2 Fan & Heatsinks
- 3 x COOLER MASTER R4-L2R-20CG-GP 120mm Green LED Case cooler
- CORSAIR Hydro series H50 High Performance Liquid CPU Cooler
- 2 x G.SKILL Sniper 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Model F3-10666CL9D-8GBSR
New Hardware:
- 2 x XFX ATI Radeon HD7950 3 GB DDR5 2DVI/HDMI/2x Mini DisplayPort PCI-Express Video Card (FX795ATDFC)
- 2 x Sapphire Radeon HD 7950 3GB DDR5 HDMI/DVI-I/Dual Mini DP PCI-Express OC version Graphics Card Graphics Cards 11196-10-40G
I was thinking of building another rig with an AMD processor I have collecting dust at the moment. This is why I purchased 4 graphics cards. I will use the Sapphire Radeon HD 7950 in the Intel rig and the XFX ATI Radeon 7950 in the AMD rig. The AMD rig will be in a midtower case.
With the existing Asus 5770, I get 175 Mhps for bitcoin mining and 155 Khps for litecoin mining. With the current rates, litecoin mining came out ahead by almost 50 cents per 24 hours. In a few days, I will find out how much more I can mine with the two Sapphire cards.
Stay tuned…
Bitcoin trading at $207 this morning. All the motivation you need to big your mining rig.
