Facts: Dell XPS 400 ordered on 3/15/2006. Rcvd desktop and added additional gig of memory. Factory mem: PC2 4200@533 MHz. New mem: PC2 5300@667 MHz (new guy mistake).
While attending an A+ class recently I discovered that my memory is only running at the speed of the slower modules, which is fine with me. I also discovered that by running HWinFO32, I can check every component in my system as well as the speed of the memory. I ran it an came up with this:

PC2 4200 @266.7 MHz, instead of 533 MHz.
PC2 5300 @333.3 MHz, instead of 667 MHz.

So, my question is, does memory lose it's speed with time, and if not, is it at all possible to adjust the speed from a BIOS set-up that will not allow you to adjust anything, like with Dell BIOS set-ups? Dell won't help unless I pay out of pocket.

Not in A+ anymore, so I can't get the instructors assistance and I'm new to Tom's HW. Thanks in advance for any help I can get.

Never mind. I just reviewed a thread that explained the reading as a single thread speed that has to be multiplied by the number of channels, ie. DDR2 = core speed x2. Sorry for shooting first.

Actually the memory just starts to go with enough time, the brain cells stop reproducing themselves and eventually it's over, oh never mind. Good job!

Even that's not quite right. P55 motherboards use DDR3 in two channels. X58 motherboards use the same DDR3 in three channels.

Either the article you saw was not quite accurate, or you misinterpreted what you read.
