90C not a big problem, but try not go any more beyond that. I'd be more worried about fan crapping out by running on high RPM for a long time.

Great setup for a hobby mining PC Within the last 5 minutes i have learned about Bitcoin, skimmed through some threads and have a very rough idea of how it all works but before i look further into this i would like to know if my Rig is good enough to Mine... Still not quite sure what "Mining" means but ill soon find out.
My Rig was built just after the new year and it was my first custom computer. I was on a budget of £500 and i feel that i made a fairly decent gaming rig for the computer, still waiting to have any problems. Anyway the spec's.
Mobo - ASUS M4A79XTD EVO
CPU - AMD Athlon II x4 640
GPU - Sapphire HD 6850 1GB
RAM - Corsair 4GB
PSU - Corsair 500w
HDD - 500GB
Any suggestions on how i should get start would be much appreciated! Look forward to your answers.
Ben

unasoft's miner will run any CPU+GPU
You can also use guiminer, it can run a cpu miner like rpc

hmm website is down for me, anyone can open the site?
edit: sorry didn't realize I had to put www in front, otherwise it will appear as empty site.

hardware is fine, but your estimate is wrong. Difficulty will increase by 60% in just 3 days. So your $85/day becomes something like $50 per day, and then there's the market crash, but if you value BTC at $30, that's up to you.

ram clock has absolutely no effect on mining, as for the core clock, you can do that yourself easily

Is it ok to put all four GPU on 1 worker? Since I don't really care about individual GPU stats.

Sempron 140 good enough for CPU, no need to go for the more expensive athlon 250
PSU 500W is simply not going to work, you'll need minimum 650W PSU, and you should probably get more in case you want to add more cards to your rig later
you should get even more than 240MH/s with 5830, probably to the tune of 300MH/s once OCed

NOT TRUE, a VM can be set up to be completely isolated from the host If you set up a guest VM on a host computer, the programs in the guest VM can not (easily) attack the host computer.
But in the other direction, it is not true. Programs on the host machine can just manipulate the guest VM, e.g. just modify the disk image file.
Thus, a guest machine for bitcoin does not make sense at all (at least when the intended goal is protection).
But a hint may help:
A wallet file does not have to be online to receive money. You can just create a wallet on a offline computer and use the addresses.
Only if you want to spend money from that wallet, it has to be taken to an online machine.

it's easier to just start buying btc on an exchange. Mining is difficult.

Trying to build my first mining rig, 3 x 6970, 1000 watt PSU, but looks like I underestimated the 6970 power consumption. The rig won't start with 3 card, will only boot with 2. I'm wondering how can I possibly save power to have the 3rd card added.
FYI:
CPU: AMD athlon X4 640 (95W, 3.0Ghz)
MoBo: MSI 890 GD70
HD: 1TB WD SATA3
RAM: 4GB single stick corsair
FANS: 4 case fan
I'm thinking maybe dropping the CPU frequency to somewhere 1.5 Ghz, this would still allow me to run ubuntu 11.04 without problem right?

When I go to download ubuntu, the download says 32 bit (recommended), and then 64 bit. But I think I'll need to get the 64bit machine for a mining rig?
I don't know if there's a difference in performance between the two. Doesn't look to be. But 64 bit is definitely *NOT* needed. I'm running dedicated miners on both 32 and 64 bit versions. Isn't 32bit only see 4GB of ram? I have 4GB ram on the machine, plus 4 x 1GB GPU, that's total of 8GB of ram, wouldn't that cause a problem with 32bit? |

I heard people saying you need 1 cpu core per GPU to maximize the GPU power. Can anyone confirm this? if that was true, then you'll need a quad core CPU for 4 x GPU, and 6 core CPU for 5 x GPU

if I use linux, I don't need dummy plugs right? just planning hardware right now

PSU 1250W is probably overkill. You'll do fine with 1000W,
1250W can accomodate 4 x 6950

hope ur getting paid for their usage  |

isn't 6970 single GPU??? 6990 is dual GPU
