Topic: 7950x4 LTC Mining Build Check (Read 2148 times)

Why do you need a $120 CPU, total waste for mining machine. Also why go with a AMD chipset mobo+cpu, when you
could go with intel chipset mobo+cpu, for less power usage, and more stable. There's really no reason to ever buy AMD
CPU nowadays, it's way behind intel.

I've build it with 1200 PSU and using sempron cpu. It takes 1400W on full speed, so warning, it needs 1500W PSU!

Get a Phenom ii x4 965BE, underclock it.
Much less power than the 6 core Bulldozer, and much cheaper!
Furthermore, I would dream of such system! I only have 2 HD7850 mining @800kh/s

Instead of paying for a PSU adapter, just jumper the green wire with any of the black wires. I used a paper clip.

Second, cheaper, PSU for the 4th card and:

The question is how to power 4th videocard :-/

keep in mind with Difficulty increase brings Price increase so dont take 90 as a bad thing... Asics only mine about 5-7 BTC back before Batch 3... thats about 400-800$ now ... lol

490 is at current difficulty, but diff will go up soon.

300 LTC in the first month is more realistic.
When more ASIC's are coming and drive GPU miners to LTC mining, it will go up faster.
150 LTC in the second month, 90 in the third month, etc.

haha, good one +1

and you can find cheaper CPU as well
CPU only server the purpose to fill the whole on mobo, so your system can boot,

Hey all,

If you could look after a build I'm about to buy it would be greatly appreciated. Mucked around on desktop before but now I'm looking at getting a dedicated miner. Will be used primarily for LTC.

Making a total investment of $1818

I'm expecting about 2480 kH/s out of it, giving about 490 LTC / month.

Given the current rates it should pay for itself in about a month, but even if it crashes and burns I should be able to hold onto it long term. Considering the money sitting in the bank will only get about 5% a year it seems like this is a better way to spend my money, although slightly riskier (much higher potential returns also).

Am I missing anything with what I'm buying? Do I need to use powered risers instead? Do I need to buy any further adapters for my PSU?

Thanks all.
