The Computer Hardware Question Thread

[Yrrek]

I need help.  Somebody.  I remember during my CIS course something about having to have the same size sticks of RAM in your computer, but that may have just been with the old old computers we were dealing with.  I don't know if that still applies.  I have a 512mb stick.  I want another one, a 1024mb one if I can.  Is this OK?  Will it work fine?

Second question.  About UPS (uninterrupted power supplies).  Are they useful, or even worth the price?  Just for using with my personal computer (gaming, homework, surfing).  I just recently had a scare with my power supply, I thought I had managed to kill everything somehow.  Turns out it was just my old power supply.  But what are your general thoughts on them?  I don't have any experience in this region.

Thanks for any answers!

For the RAM, newer motherboards don't care if the RAM sizes are different, as long as they are the same type (i.e. DIMMs, SIMMs, etc.). You will need to check your motherboard manual though to see if your board will support 1.5GB of RAM. Some do not.

As to the UPS, I reccommend them. Make sure the battery will stay on long enough for your computer to shut up in case of a power outage, otherwise it is just a glorified surge protector.

Newegg,com has some great deals on everything.
