Hello,


Is it good to combine two different brands of memory on same board ?

Adding a 256mb simpletec and 256mb kingeston on a p4 intel mb. ?

Btw, are banks accesses by order, that is bank 0 is first then bank 1 next ?


Can anyone recommend a software that tests memory chips ?

Thanks.

I've no experience with a P4 specifically but IME it usually works at
"standard" timings but if the latency specs are different you'll certainly
have to run both at the slower one. If you overclock you're more likely to
have problems. Why do you want to do this though? There's also the fact
that every system misbehaves from time to time, mostly due to software
issues but why add in another variable to confuse the diagnosis of a
problem... and DRAM is cheap just now.

By "banks" do you mean DIMM sides? Yes, physically they are addressed in
ascending order but in a protected mode OS, you *can* get fragmentation of
the physical memory space in its logical mapping to program space.

I can't connect to <www.memtest86.com> right now - possibly since my ISP is
having routing problems - but that's the one you want. Do a search at
Google on "memtest86".
