You can scale down the size of your area lights and that will help. The smaller they are, the faster they will render. Set the area light quality to 2. Turn on Shading noise reduction later if you need it to smooth out the shadows. Turn off all of the raytracing features except for Raytrace Shadows. It looks like your camera may be looking through a window, so if you are raytracing transparency and refraction that will really slow it down. Use no Antialiasing or just 2-3 PLD passes and the Mitchell Reconstruction Filter.

Radiosity may actually help speed it up if you use interolated radiosity and turn off the area lights.

For a test you can use these settings:

Ambient Intesity: 20%

Check Shading Noise Reduction

Type: Interpolated

Check Cache Radiosity if you are rendering multiple frames.

Intesity:100%

Rays per Eval: 3x9 (you may want to increase this if it looks patchy.

Indirect Bounces: 1 ( you may want to increase this to 2 or 3 later)

Tolerance: 0.1

Min Eval Spacing: Set this to match your grid size from the screen grab. If your grid is 1m then set it to 1m. (you may also need to adjust this if patchy spots are a problem)

Your system is slow but you should be able to get a render out of it. Just keep the render resolution at 640x480 and no more than a 50% multiplier for test renders and you should be OK.

Good luck!
