Memory in Quadra 950

[Elv1s]

I have bought 2 second hand memory modules of 4mb each to put in my Quadra 950 and they arrived today, but it have a sad Mac start sound…mem fail. So I checked the manual and learned that memory needs to be installed in 4 not in 2:s (that I thought) so I found 2 more modules but of a diffrent brand but they come from another Quadra 950. So my question now is can I mix modules of same size but from diffrent brands in the same bank? (se pictures, the pic with black plastic bankground is the 2 I have)

Yes, that is fine. As long as they're the same size, it should be ok.

Thank you

Sure. Not a problem.

Sure. Not a problem.

I forgott to mention that I have a PPC-card inside. Someone informed me that that can make it more demanding when it comes to memory modules. Know anything about that?

Most 30 pin SIMMs are 60-80ns and are just fine. There are very old SIMMs (probably 256K nobody wants to use anyway) that are 100ns, avoid those.
