I've heard 10%+ penalty on speed for using the non-SC drams. I've not noticed that they're any cheaper if you go with 1 meg chips instead of 4 meg, and the following justifies why I bought the 1 meg chips. Add 256K static col. zips relatively cheaply, but limiting expansion to 6 megs Add 1M s.c. zips at a higher price (best I've seen is $54@), but have to add in 4 meg increments (8 chips)... Unless you're going to go to over 6 meg right away, then I wouldn't bother with the high-density chips. Remember, they're still very new, and the prices will go down quickly. The best numbers I could find were $6 for the 1 meg parts, so that for meg was just under $200, vs. $45 for the 4 meg parts, so that 4 meg is just under $400. Now, if you don't need to expand until the price drops by 50%, you break even for cost. With 1 meg parts, you spend $200 (4 meg now) + $400 (8 meg later), and have 4 meg of 1 meg parts to sell. If you buy 4 meg of the 4 meg parts now, you wind up spending $400 (4 meg now) + $200 (4 meg later), but don't have the 1 meg parts to sell, and haven't had the $200 to play with in the interim. I've got more memore than I've ever had before (5.5 meg vs 5 in the 2000), even with kickstart in RAM. Running 2.0, many of the hacks I used to run now live in kickstart, so there's actually more free memory than that 512K left over. So, the question are: 1) What applications you got that require more than 4 meg? 2) Prediction on how long until the 4 meg parts drop to $20-$25/chip.
