I have a Gateway 386-33 with 256K cache, initially it had 4 MB memory
(4 1M SIMMS, 80ns, three chips on each SIMM). In June, I purchased 4M
from Gateway. These new SIMMs are 70ns and have 9 chips each,
supposed to work fine.

The system boot time memory test never fails. But I was never once
able to compile 0.97. Each time I compiled, there was a different
problem, cc1 cpp and so on. The problems were not predictable nor
entirely reproducible.

Sunday, I got a copy of SLS0.98p1 and tried to install it. Some wierd
things happened and I wasn't able to get a clean install, tried about
four times. So I proceeded to pull out my memory expansion card with
the new SIMMs on it. Remade the file system and then the installation
went without a hitch.

So my question is has anyone else experienced anything like this?

Do you have any idea what could be causing these problems? Bad SIMM?
Bad memory expansion board? Wrong kind of SIMMs?

I plan to try to make the kernel with the original 4M and then again
with one additional SIMM each time.

Any and all help is greatly appreciated.
