I have an opportunity to get an old Pentium 266 dual CPU PC. I was wondering if this would be able to one overclock and two, if it would do any good. It does have two slots for sdram but I dont know how much I can put in there. I am going to try this out with a Live distro of linux and it will only be used for Folding. Is this even worth spending the time doing? I know that every little bit helps but if the benefits are not going to outweigh the money I am spending on electricity I won't mess with it.

 
You can run the console version, run two separate processes, and have one instance of F@H for each CPU. That's the way I'm running it on my Dual PPro @ home
 
Is there any way to get both CPU's working on the same project? The thing is this will not have alot of RAM in it therefore I think it would be better just to run one at a time. I am new to the the Dual Processor scene so I am just asking question before I jump in head first into thei project.
 
You can't have both CPU's running the same instance, or as you said 'the same project.' The Folding@Home client does not work like that, nor would it complete Work Units (WU's) any faster. One CPU, One Instance.

How much ram is in the box, and what OS are you going to be running?
 
Prolly a *nix distro. Havent decided yet. It will be Live CD though. I am trying to do this from parts just laying around and some old boxes that I have been given that are just piling up. I dont know yet how much RAM I will have. Maybe only 128MB of SDRAM. The other thing that I would like to know if anyone has had any success with overclocking these. The have active cooling on them and if they run anything like my wifes PIII 450, do not run hot at all.
 
With those speed processors, all you'd be able to run reliably are timeless tinkers. Normal projects will probably be a stretch to turn in on deadlines. You might be better served by selling that if you can, and maybe look into a cheap Semperon or other low end PC setup. Anything much lower than around 667mhz probably falls into the timeless tinker category as well.

 
Thank for the input. I dont think that I will mess with it. Maybe set it up as a file server or something.
 
Well if you plan on running it anyhow, by all means run the timeless tinkers on it, or possibly even the UD project. Granted it won't get any huge volumes of work done, but it will be doing its part while its just sitting there serving up files. :D

 
If you will use it for something else, then go ahead and run F@H on it. Just make sure it's set to timeless tinkers. I have a dual PII 266 system and once I get another hard drive in it, it will be up and folding again. I have no problem running WinXP with two instances of timeless tinkers running on it with 256 meg of RAM. It's no massive points machine and it's not really worth running to just run F@H on it since the number of points it produces vs the power used is not a good ratio. If you have plans for something else for it then go ahead and run the machine. I plan on turning mine into a file server eventually.

Also, there is no way we can tell you if it will overclock unless you tell us what motherboard will be running the CPUs. There aren't a lot of dual boards around that time that will overclock very well. They were made for stability, not performance.
