Usually you have to try such things.
Well dad blast it!!!! I was not paying attention to this memory I bought. It turned out to be registered. My brother has been complaining about his computer, which he should...it's a 333mhz. I got him a cheap 1.1 celeron off of ebay. It's a compaq looks like some sorta 4400 series. Will this computer (beginning a consumer brand) even SEE the registered memory and use it as nonregistered if all registered is in it?
