Litecoin miningrig

litecoin miningrig
I decided to start mining some Litecoins (LTC). After thinking about it some months now I gathered some parts together of which I think they should suitable to mine some litecoins. I checked this page about hardware comparison for litecoin mining: https://litecoin.info/Mining_hardware_comparison and choose for the Sapphire R9 280X 3GB GDDR5 OC VAPOR-X and what the hell, bought 2 of them. Still in doubt about the OS… Linux or Windows. Windows maybe easier to set up. Linux is more stable. Maybe I try both 🙂
Here is the list of hardware I ordered today:

CPU: AMD FX-4300 Boxed
Mainboard: ASRock 970 Extreme4
Memory: Corsair Vengeance LP CML8GX3M2A1600C9
GPU : 2x Sapphire R9 280X 3GB GDDR5 OC VAPOR-X

A PSU I already have: Corsair CX750M, should be enough to power 2x 250W max for the GPUs and 1x 95W (max) for the CPU. If not.. I will have to buy a more powerful PSU but we will see first how this one will perform. The CPU will be undervolted so it uses less power, CPU power is not important for Litecoin mining, the GPUs do all the work.

Each GPU will hash at ± 750 kH/s so total hashpower should be around 1500 kH/s. That’s ± 14 LTC a month with current difficulty of 3231.183.

I hope to receive the hardware just before Christmas. How I will setup this rig and what my struggles and experience will be with the litecoin rig you can read here laterrrr…

  1. dude, do you have the correct config for the 2? we have exactly the same build on GPU

      • I have with this, the configuration file at around 720kh / s
        How can I get faster?

        • I am not getting 750kH/s those are peaks. Average is about this:
          GPU 0: 60.0C 3066RPM | 709.5K/711.5Kh/s | A:6875599 R:17582 HW:0 WU: 657.7/m I
          GPU 1: 59.0C 2461RPM | 732.0K/729.9Kh/s | A:7009376 R:25646 HW:0 WU: 670.0/m I

  2. you’ve got 750 kh / s pop GPU? I’m also waiting for their graphics.
    thanks for your reply

  3. with this config file.

  4. sorry, your configuration file :). Are you aged 750kh / s per GPU?
    Are you still doing some changes to the configuration files?

  5. I am not getting 750kH/s those are peaks. Average is about this:
    GPU 0: 60.0C 3066RPM | 709.5K/711.5Kh/s | A:6875599 R:17582 HW:0 WU: 657.7/m I
