Mining on CPUs with 300 computers?

[HuLaN]

New to bitcoin and I'm a bit curious about the mining side of bitcoin.

Hypothetically speaking, If I have access to ~300 networked computers at work and have ways with a queue manager to easily monitor and launch processes or run python scripts on these, what kind of output can I expect when only mining in the CPU?

A bit mixed setup but average is:

- Linux 64bit
- 2x Xeon Quad processor @ 2.4 ghz (8 physical cores, no HT)
- 16gb ram
- Simple office graphics card. No GPU mining
- shared 50mbit Internet connection

Let's say that I'm allowed to utilize these machines for 12 hours a day and don't need to worry about electricity.
How much gigahash and bitcoin would this setup generate a day? 

Cheers

Find your CPU on this page: https://en.bitcoin.it/wiki/Mining_hardware_comparison#Intel and multiply the Mhash/s by 300. It looks like the fastest is about 20 Mh/s, so you might get 6 Gh/s. At least that is more than a Jalapeno.

Thanks for link! too bad though..  not enough return to have that many machines running at full steam for the return that something the size of shoebox can do... crazy

Should be careful. Can probably damage hardware if you leave if unattended. How are you going to monitor temps or reduce workload if heat becomes an issue?

Mining BTC/LTC with CPUs these days aren't worth it. Perhaps some sort of other altcoin. But, if you were to mine a Bitcoin over the course of a few weeks (and use thousand USD in power costs), it may be worth it to sell the single coin in 20 years from now when that single coin is worth a small fortune.

I don't recommend CPU mining for anything other than some obscure altcoins that "may" be kinda worth something someday.

Also, (obviously), you might have to worry about potential legal trouble.

Just saying, it's been tried before and people have been punished before.

go scrypt!

I get ~120Kh scrypt from two 6core xeons.. one i5 quad core got me 50Kh so I'd say at least minimun 300*50Kh = 15000Kh and max 30000Kh is possible depending on your hardware... that's 25-50LTC/day or 75-150usd/day

on the other hand, those xeons of mine rise power draw by around 100W per server on full load, so that's also an extra of 30kW/Day power to pay and 30kW heat do dissipate
