Why? This chipset is coming out for Intel, too. It'll be a few months later than the AMD version, but pretty soon you'll be able to have it either way.

It's Mushkin basic RAM. I don't think it's on the list. Do you really think Mushkin RAM and Asus boards are incompatible?

I've got the Asus p5gdc-v deluxe, which supports DDR and DDR2. I'm using DDR (only). The memory is PC-3200, and the mobo supports that, but when it posts it says PC-2700. cpuz also says the memory is only running at 166MHz. I've tried letting the mobo detect the memory from SPD, and manually...

Okay, I didn't really think about full power planes, but that makes sense. I was doing some back of the envelope calculations with 1oz (34u) copper and I needed a trace at least a foot wide. With a thicker dedicated power plane, that would ease the requirements a little, and I suppose the...

I read recently that Prescott dissipates something like 90-100W, and its voltage supply is 1.4V. So that's upwards of 60A of power being delivered to the processor. That's a heck of a lot of power. A normal household circuit is designed for 15A and uses 14 gauge wire. So that's like four big...

Take a look at the IEEE Transactions on VLSI Systems. Any good engineering library should have it.

I'm sort of out of my depth here, so it's all just speculation. Ross, I think you're right that interactions with atoms complicates the problem. It's not because the wavelength of light is so much smaller than the wavelength of other radio frequencies. 600 nanometers is still huge compared to...

Yeah, exactly, the antennas would be sized on the order of a few hundred nanometers, and spaced similarly. I guess you could do it with MEMS, nanotech stuff, but that still doesn't get you the 500THz signal source and the ability to control the phase relationship between each of the antennas...

With an array of antennas, you can steer a beam electronically. There are radar systems that use this method, so there is no mechanical movement. In theory, since light is just another form of elecromagnetic radiation, you could do the same for light, but the frequency of visible light is in the...

Not sure of a way to do this electronically. Many radar systems just use a mechanically rotated dish, why couldn't you do that with your laser? Or keep the laser fixed but rotate a mirror. It's low tech, but it gets the job done.

So you're trying to create a computer controlled goalie? Cool project. I would say 2 and 3 either won't work, or would be ridiculously complicated. 1 will likely work, but like you said, you need a high capture rate, and very low latency to work. If you can make a hardware or DSP solution...

You can't measure the distance to the moon and the speed of light. Since what you're actually measuring is a time, speed will depend on distance, and distance on speed. Presumably they use the known speed of light, and use the mirror to measure distance.

I'm not sure if it was the first, but the first accurate way of measuring c involved rotating mirrors. Rotate a mirror very fast. Shine a focused light on it (laser is best, but didn't exist when Michelson and Morley did this). Light will reflect off mirror, travel a certain distance, reflect...

In general, a buffer passes a signal unchanged, but with higher drive strength. (Drive strength relates to how much load a signal can drive). Since the clock goes to thousands of registers on a large chip, it must have a huge drive strength. The clock source (typically an on chip PLL), doesn't...

When I read that "the amperage is too high," what I assume he means is that the current draw of the motor is higher than the transformer can supply. Which may or may not be true, depends on the rating of the transformer. If it's too small, something will eventually give.
