    I did take your advice, fRee_, and went with an 850W EVGA G2 Gold PSU. I can grow with it.
    I'll plan on putting that and the GPU in the old Dell (has 1 spare 16x PCIe and 1 spare 1x PCIe) unless I hear anything against it.

    Open cases for rigs look like that: scheme and photo1 / photo2. There you'll see how to position external fan. ;)

    Yes, you definitely can repurpose your old desktop and start with one GPU. :) In fact, that's exactly how I started two years ago.

    Excellent PSU. It will easily power three GPUs. I won't say anything against - that's a good first step you've made.
    The only concern is if the profit will be enough to pay it off.

    I thought mining was starting today? not sure where I remember that date from. Will instructions be posted here when it starts?

    Would you mind posting the full spec of your rig? I'd like to assemble something myself - mostly for the learning experience and supporting the network when it launches - less so for chasing profits.

    Thanks!

    Hi Esper,
    I will be running a Dell Inspiron 546
    1 spare 16X PCIe slot
    1 spare 1X PCIe slot
    CPU: AMD Athlon X2 215 2.70 GHz
    Ram: 4 GB
    Windows 10 Home 64-bit
    850W EVGA G2 Gold PSU

    I just replaced the power supply with the one mentioned above (very easy, and the machine still runs; so that's good). The stock one was 140 Watts.

    The on-board video card (integrated) is an ATI Radeon HD3200.
    I haven't purchased the GPU intended strictly for mining yet as I was waiting for some test results from the forum. If I get antsy, I may go ahead an purchase a Sapphire Radeon Nitro R9 380 4GB at $220. Any thoughts on that one from the vets are welcome.

    I'll say, at this point I may not be the one to be emulated. Still, happy to let you know how everything's working on my end and help on the way as I'm able.

    Anticipating testnet this week, I did go ahead and order a Sapphire Radeon Nitro R9 380 4GB at $220. With success, I'll let you know how it works.

    GPU install was a success. With testnet binaries out, was able to start mining. The GPU is averaging just under 1 Gh/s (935 Mh/s) using cgminer, no optimization.

    Am I reading this correctly 24,083Gh/s?

    That seems really low. I am inputting 1.142Gh/s by myself.

    GPU 0: | 1.151G/1.142Gh/s | A:2771 R:0 HW:0 WU:3887.6/m I:12

    No @drunkenmugsy, really low is my Radeon HD 4350 at 30 Mh/s. The numbers that I see here are not bad.

    Not bad. My 2011 27" iMac w/ Radeon 6970M is getting on avg. 600Mh/s

    Yeah not shabby for an older machine. I think you may want to tone it down even more though. From my understanding the A:680 R:680 means you had 680 units accepted and 680 units rejected. You are pretty much just circle jerking there.

    Thanks for the information. Any idea why that would be happening and how to tone it back?

    I am not a guru but you can try taking your intensity lower until you stop getting rejected work(or at least >1%). If you push GPUs past certain limits(different for each card) it starts introducing errors causing rejects. Small errors may make for miscalculations. In most cases it may not matter if you get 1.00123 instead of 1.00122. That small change however would throw off a HASH entirely. Less intensity sends less data to GPU. You do less work as a result. You have a pretty low, WU:4.4, as well. It may not even be worth it to mine with that rig if you cant get the rejects down and the work units up. It may take several hours to try each setting. Dont change a lot at once, typical troubleshooting methods etc etc.

    Each column is as follows:
    A: The total difficulty of Accepted shares
    R: The total difficulty of Rejected shares
    HW: The number of HardWare errors
    WU: The Work Utility defined as the number of diff1 shares work / minute
    (accepted or rejected).

    This may be true. I was going by what I read in link below. As stated I am not a guru... hehe
