Also, I never said to OP anything along the lines of the GPU not making up for any PPD lost on the CPU due to folding on a 460 - so I'm not sure why you point that out - I told OP that it would be worth it if he wanted to fold. 8-10K PPD is how many PPD one can expect from a 460 - with 10K being overclocked. So on top of his CPU, about 14K PPD or so might be worth it to OP smile.gif

I only pointed that out because it's true and wanted to convey that to the OP. I wasn't trying to 'prove you wrong' or anything like that, just correct your mistake and give my 2c to the OP. smile.gif

Oh you ought to consider folding on your 670, it can pull 30k+ PPD.

There is little load on the CPU...for now. The new core will be OpenCL, like AMDs. So it will use some CPU when it comes out.

So if I get a semi-decent videocard looks like it may work. Thanks everyone thumb.gif

Hate to "revive" old threads but I had this exact same question. I have an even lower-end build. Sempron 145 ( OCed @ 3.7 GHz) 2 GB DDR3, integrated GPU (which isn't contributing atm due to Ubuntu). It looks like it's doing nothing (I mean it is working and is maxed out). But hell I figure I have a bunch of PCs doing absolutely nothing collecting dust. They're not going to like "get in the way" or take projects someone else could've had right?

I tried to unlock its second core under Windows but experienced strange behavior (web browsers looked extremely weird, certain applications such as Cinebench wouldn't open) however Prime95ed it and never failed/crashed. I'm gonna see if it is able to handle unlocking and/or overclocking. It'd be a hell of a lot more useful being a multi-core.

Edit: Forgot I posted here about it. http://www.overclock.net/g/a/745589/overclocking-unlocking-my-sempron-145/

I've folded on a regor 240 which is basically your sempron with both cores, in both unicore and dual core configurations and it's not a huge difference. You'll be looking at about 800 PPD running in uniprocessor compared to around 1,800 PPD if you can get both cores working. Either way I wouldn't be folding on just the CPU alone regardless of if you can unlock both cores because best case scenario your getting 1,800 PPD for ~90w minimum. The best use for an old weak CPU when it comes to folding IMO is to use it as a machine to stuff dedicated GPUs into, because the CPU should still be powerful enough to feed GPUs.

at the risk of sounding like a skipping cd any ppd will help the teams and man kind in the long run so yes it very much is ok to fold with old or even low end machines and thank you for doing so atm i cant myself im living with a flatmate and im not the only one paying the bills and Australia is too expensive with electricity though im moving to Nevada Las Vegas soon enough and the electricity prices in the u.s.a. are not as steep so i will help there with a new GPU and a higher OC all around perhaps even a 3770K and revo 3 with 1.5Gb/s read and 900MB write speeds and eventually with a GTX 770 or another 670 in the not too distant future also if not even better!!!

Ubuntu refused to boot with both cores enabled. Pretty much expected that to happen.

PSU is only 400w (as built a year ago without folding in mind). Will have to work around that or upgrade the PSU. Is it worth trying to find a GPU that'll work with 400w or should I invest in something bigger?

I'm also gonna dedicate two Pentium 3's to the cause (assuming they can run Ubuntu). Why not right (lol)?
