Bought 2 new Corsair 512mb 400mhz sticks to add next to the already existing same spec Corsair sticks.
Turned power off, gave the two unused sockets a burst of compressed air to get any lurking dust, installed them and secured the latches. Booted up, BIOS clears the CPU, displays the correct new total of RAM, then freezes.
Tried the 2 new sticks by themselves in the 2 unused sockets, starts up fine. Tried 2 new sticks in the sockets that had been occupied by existing RAM, starts up fine. Tried 1 new stick with 1 old stick in both sets of sockets, starts up fine. Anything more than 2 sticks of RAM causes a freeze after the BIOS recognizes the new amount of RAM available.
Talked to a friend, he said it's possibly something in the BIOS settings preventing me from using more than 2 sticks, but doesn't know how to change it himself.
What's the RAM voltage and can you increase it slightly? The required voltage should be displayed in the SPD tab or on the modules. Since you installed 4 modules, try adding .1V, e.g., go from 2.5V to 2.6V. If that doesn't work, provide a link to your modules.

It's listing 2.5v on slots 1 and 2, I'll go into the BIOS then and up it to 2.6v then check, etc. Thanks.
I went into the BIOS setup and into the Cell option to change the Memory Voltage. It was listing it as already being set to 2.65v, and I bumped it up to 2.70v. (options only allow bumping in increments of 0.5v). Powered off, added the 2 new sticks of RAM again, and no progress has been made, startup still freezes after displaying the memory total.
Then you should contact Corsair to ensure that the modules are compatible with your motherboard when 4 are installed. We can't do much more if we don't know what modules and motherboard your have.
