Folding on a GT630 and GT640

I have a GT630 and GT640 folding for me, and there isn't a lot of information on them, so I thought I could share some light.

The GT630 cost me right at $50, new at Fry's because it was an open box. Normally they're about $10 for the Gigabyte version that I'm using. It has a maximum wattage of 50, which means it sips power. I currently have it clocked at 875mhz and on a 7625 WU it's averaging 28:09 TPF, 7209 PPD. There's also plenty of thermal ceiling to get it clocked higher I believe, as it's only running 60*C.

The GT640 I've kept better track of. To start with, I got a refurb from newegg that cost me $67, shipping included. It has the same 50w limit, and this one is made by EVGA. At stock clocks, on a 7660 unit, it has a TPF of 8:45. I've got it stabably OCed to 1080mhz, with a 10mV increase, and on a 7660 it's now getting a TPF of 7:32, and 8451 PPD. At 1,000mhz, I got a 8071 WU and averaged 5:47 TPF with 9618 PPD. I believe this card can go higher as well, and I'm working to push it. Currently it's running a cool 41*c.

I'll update this thread as I continue to push higher limits of both cards. I'm absolutely positive I can get 10kppd on the 640 given the right work unit.
