Good for you! Isn't lots of memory just grand?

Oh, no, no... you can check...

Funny you should ask...
   Look at the individual memory modules (chips) on the SIMM boards. Up
in the top right corner of the chips there should be a speed rating. "-15"
means 150ns. "-12" means 120ns. "-8", unsurprisingly is 80ns. These methods
of marking have been consistent with all of the SIMMs that I have seen, though
I am not certain that yours will have the same markings (but more likely than
not, I think). I honestly don't think you'll notice a large difference between
150ns and 120ns. Those are the maximum amounts of time that the chip could
take to return the info. Most chips will perform below (i.e., faster than)
their reported speeds. So what's a few billionths of a second between friends?
