In the standard DDR3 "fly by" topology, there is a significant delay from the time that an address or command signal reaches the first DRAM on the module to the time that it reaches the last. That's a fair amount of latency across the bus that has to be accounted for in memory timings. In a...

I've got a variety of Sun computers that are all way past the three year mark - one SparcStation 20, three Ultra 1's, two Ultra 2's, an Ultra 5 and a Blade 100. Does that count? I've got a 7 year old Micron notebook and a 4 year old Toshiba. Prior to my new build, my last PC was good for...

Madstork, I'm not sure if your question was rhetorical, but I'll take a stab at it. You can't have analog anymore because everybody and their dog has a cell phone. The call density is just too great to process the number of simultaneous calls per cell that analog will allow. Add to that the...

I don't have a problem with the size of the phone - I have a Cingular 8125 now and actually wish that it had a screen more like my Palm LifeDrive (which is a catastrophe of its own). I thought that I would have a difficult time getting used to dialing on the touch screen, but it isn't a problem...

Is Clearwire around in your area? They're pretty popular where I'm at, particularly for folks a little further out in the country. I haven't heard a lot of good about satellite internet. Between rain fade and really high latency, I'd say that it's a solution of very last resort.

Holy cow, that looks like a signal integrity engineer's worst nightmare. I can only imagine just how hard it would be to get any kind of useful signal from the memory controller to the box and back again! And I wonder how they think that the computer will manage to synchronize the signals if...

Also, consider other interference sources, such as bluetooth, microwave ovens, and practically anything that is wireless and uses radio frequencies to transmit. Also, range is affected by the number and thickness of the objects in the signal's path. Walls can be a problem, particularly if the...

Actually, this could be an excellent overclocking board. It removes one of the most stubborn problems that memory modules introduce: the socket. The socket presents an impedance mismatch, a break in the return current paths and a source of radiated noise. With good quality memory (which is...

I'll put in a plug for DarkSynergy's first 650i recommendation. I have that board and it is definitely a winner. It's kind of a Frankenstein's Monster of parts, but it sure does get the job done with style and performance.

The drill that you're talking about is called a hole saw. The bit in the middle starts the hold and aligns the saw (the part that looks like a can). You can drill the plexi with one. Before you drill, cover the area that you're going to drill with masking tape so that you don't mar the...

Intel's Bearlake (P35) chipset supports DDR3, if the motherboard manufacturer elects to include it. I think that Gigabyte and Asus have just released motherboards with both DDR2 and DDR3 sockets. Be prepared to drop some serious cash, though...

I don't think that the RV systems use Freon. If I remember correctly, RV-type refrigerators use either ammonia and water or ammonia, water and hydrogen. They also operate at very high pressures. In the ammonia and water system, the heat source causes the ammonia to boil out of the water, then...

Live and learn!:eek: At least now you know what the problem is!

When I say "loading", I mean that when you put two modules in a single channel, the address drivers in the chipsets have to drive a total of 32 "loads" (each memory device represents a "load" on the driver). The address driver sees the chips as little capacitors - 32 of them. So, based on a...

Ideally, the BIOS will look at the SPD and configure the system for the slowest memory speed. The Ballistix modules _should_ run at the slower speeds of the Firestix, but it's possible that the table doesn't have those speed grades programmed. If that's the case, then you'll have to set the...

Everybody would love a notebook that had a huge hard drive, super fast processor, loads of RAM, a big screen and a high performance GPU. Oh, and 10 hours of battery life. And make it weigh two pounds. Those last two are kind of a problem, eh? Hard drives only have so much areal density...

Look along the short edge of the Crucial module and see if you can find either a four digit number that starts with a zero or a three digit number that does not. Post it here and perhaps I can help you out.

At work, my system has 12GB of RAM so that I can run multiple 3D electrical simulations at one time. I can get close to eating up all of the memory - the CAD program manipulates incredibly huge arrays of numbers. Other than that, I'm not sure what I'd do with that much memory.
