Upgrading to more ram

You probably won't want to upgrade DDR (not DDR2 or DDR3) RAM because it is very old and expensive (because it's hard to find).

You might be able to find someone here that will give you their old DDR 400 RAM cheaply or for free. Try posting in Classfieds.

You may want to start looking into building a new computer. That can be done for as little as $250. If you are interested, feel free to ask or post in the forum.

Make sure that the new memory modules have the same operating voltage as your current memory modules or you'll run into incompatibility issues.

I had an A8n-SLI Premium and I never had any success running 4 sticks of memory..  

I couldn't even get into BIOS with 4 sticks installed  

I have an A8N-SLI Premium. I use it as my alternate computer if my primary one fails.

All four memory slots are populated with 1024 MB memory modules and it works fine. The Command Rate has to be set to 2T to get all four memory modules to work together.

The memory modules should all have the same timings and voltage. Any mismatch will give you nothing but headaches.

As far as running with all slots populated: Reduce speed and timings, then install memory and it should post and allow you to get to the bios. Then change settings to auto (although you might want to bump voltage to 1.9 or 2.0V). It should continue to post and boot. You can go to the bios to tweak settings after that.

Thank you very much everyone!
