I think the GA-G33DS2R has been discontinued. It's a shame, because it's a really nice uATX form factor board. I was hoping to get another to put a 45nm quad in at some point. I suspect that both of the boards you linked to will have undervolting in the BIOS. But it's less of a gamble with more expe...

I didn't actually try overclocking on stock voltage. But from reading a lot of the threads here and elsewhere it looks like a good rule of thumb is that you can either overclock about 20% on stock voltage, or undervolt about 20% at stock speed. Now, since power consumption is proportional to the squ...

To answer KansaKilla's question, I'm running linux and it's very easy to run two instances of folding under linux. Just make a directory for each client, and start each client in it's own directory. Nothing more to it than that. To answer VanWaGuy's question, yes, there is an issue with quad only li...

Other than being diskless, there's nothing special about my systems. For example, the Q6600 system has the following: Motherboard: GA-G33M-DS2R (uATX with BIOS support for undervolting) Processor: Q6600 (G0 stepping) RAM: 2x1GB DDR2-800 (OCZ-Gold I think) Case: Antec 3480 Power Supply: Earthwatts 38...

There's a real trade off between maximizing performance of the hardware through overclocking and minimizing power consumption through undervolting. Since power consumption of the CPU is proportional to the square of voltage, a little voltage change makes a big difference power consumption. My machin...

Same story here. I have a 2.8 GHz P4 that's no longer in use. It was producing about 100 points per day and consuming just over 100 watts.

In contrast, my most efficient folding box is a Q6600 that is producing about 3600 points per day and uses only 80 watts.

Congratulations to you Viking for reaching the 1 million point milestone.

I built my kernel from source because I wanted a small non-modular kernel with just the stuff I needed to support folding on my hardware.

But it did turn out to have other benefits :)

I usually keep an ssh session open in a terminal window to each client and check the logs a few times a day to make sure things are still running (but they almost always are). Maybe once a month I need to fix something. Work unit files are backed up to my main machine every half hour. So if there's ...

I have a setup kind of like this for my folding machines. They're on my main network, and they netboot from my main machine. Every 30 minutes, they tar up the folding data files and tftp them back to the server machine. When a client is started it checks to see if there are saved files on the server...

I'm running a couple of BE-2300 systems, both undervolted. I don't think I'd try running passive with the stock heatsink. But they don't need much airflow at all to keep them nice and cool. And the stock amd fan is very quiet if you run it very slowly. And you can't beat the price. On my first BE-23...

FAH recommends quads for the SMP client, but it runs fine on dual core machines, and generates a lot more points than the regular client :D I'm folding with a core 2 duo E4500 and two amd X2 BE-2300's all running the SMP client under linux. As far as I can tell you get about 20% more PPD with Linux ...
