Can you mix the RAM speeds? I thought that was a no-no. I found this on

You can use 60 or 70 or 80. Just don't mix them in an A3000 or you'll have all sorts of mysterious errors. I used to get little glitches randomly on my screen because of a single 80 getting mixed in with a bank of 70ns ram. I recall taking about 2 days to track down what the deal was way back when. (We all blamed Amber, and replaced it, but that didn't solve the problem, finally noticing that one different zip and changing it solved it after a whole lot of cursing and fist shaking.) :-)

Stick with all 70ns (they're the most common next to 80ns that I can find).

Although, you might be able to mix 80's and 70's if you pair them in different banks. From what I recall you want to fill bank 0 first, then 1 then 2 then 3. If you are missing a chip in bank 2 you won't see the ram in bank 3 (unless I recall incorrectly). The 3000 (and 3000T) motherboard needs to have the RAM populated bank at a time (you can't just shove ram in the bottom 8 sockets and expect to see it all or be able to use it all).
Would these 80ns chips work?
