can't get new stick of ram to work with old stick

[alfhead]

specs:

amd TBird 1 gig
Shuttle AK31 rev.3
256 meg crucial pc2100 ECC Registered
256 PC2100 hynix chips nonECC nonRegistered


ok, so when both sticks of ram are in my comp, only 256 megs get recognized. Everything works fine, just that the other 256 is absent. When just the crucial is installed, the comp works. When just the Hynix is installed, the comp works. I just can't get my system to recognize the full 512 megs. any ideas? are these rams incompatible?

the problem should be registered and unregistered...

you should use one kind of ram in your system

I have experience with mixing 2 kinds of ddr ram in my system, the result is unstability

I was mixing two stick of samsung pc2100 with hyundai pc2100, i just get frequent lock up

but once i took out the hyundai (sp?), everything seems fine....then i swapped out the samsung with the hyundai ram...it ran fine too

So, is it not even cool to mix different brands of stix?

I've mixed stix before and it hasn't caused any trouble at all. Hmm. What can you do I guess.
