[Ethereum] mine Ethereum from AMD Laptop

I tried it and here's what I found out:

1. Unfortunately the motherboard wouldn't work with the GPU and the powersupply that came with it was proprietary (Dell) and couldn't be used with any other motherboard. I did buy another old motherboard for cheap and it worked fine. So no, as long as the components don't slow down the graphics card then you will have no problems.

2. The speed from the RAM sticks doesn't matter from what I have found. I believe only the graphics card RAM is used for mining. That is why overclocking the GPU RAM has such an effect on hashrate.

3. No idea. But it won't effect mining.

Nothing forbids you to mine Ethereum, however mining such as mining bitcoin,litecoin or Ethereum is most of the time not profitable unless you have a very low cost of power.

Below you'll find some links, however i recommend you if you want to mine - ether, litecoin or most known cryptocurrencies - to mine on a pool instead of mining on your own where you'll have no chance to mine a whole block on your own unless having a mining farm or being the luckiest person in the world as both btc, ltc and eth are mined with PoW.

Mining on a pool makes allows you to join a pool of miners where the reward is distributed beetween all those that contributed in mining a bloc minus a small fee for the mining pool.
