I have a Gateway MX6426 that has 1GB factory, which is two 512MB SODIMM modules. So I bought one Patriot PSD1G33316S module hoping to replace one of the 512MB modules, ending up with 1.5GB total.

All the specs match the original. PC2700, 333MHz, CL2.5, 2.5V, Non-ECC, and according to GW, the computer can have a max of 2GB. When I replace one of the originals with the new Patriot, I get no POST. I get lights, HDD spins up, but no display, no beeps.

So I take out the 1GB leaving just one 512MB. It boots.
I take out both modules, and put in just the 1GB in the other slot. Nothing
I replace that one with one of the originals, so the machine has only one 512MB. It boots

I try different combinations, and everytime the 1GB module is present, it refuses to POST. Otherwise, regardless of the arrangement of the 512 modules, it boots. The new 1GB module fits just like the originals.

Now if I go to Patriot's website they only list 512MB modules for this computer, but an Amazon reviewer said they did exactly what I did on the exact same model and it worked fine. That's the last time I'll believe that.

But still, what's the deal? I've never had trouble buying RAM before. The specs match.....what else is there to do?

What I would do is put the old ram back in and open your web browser and download this http://www.crucial.com/systemscanner/ I use this all of the time if there is an ageing system that I'm unsure of what ram upgrade is the best possible for it. Try to run it once and tell me what you think

I forgot about that tool. I ran it and it suggested RAM with the same specs as what I bought. Unless this module is defective, but I know that's fairly unlikely.

Are you running 64-bit or 32-bit? Just found a tidbit of info, it seems (if I'm reading it right) that model only supports higher RAM with a 64 bit system..... it also mentions slightly different RAM for upgrade than what you're trying. Although I'm fully aware it tends to depend on who you ask ;)

The type of OS will make no difference since it's not even displaying POST.

I'm returning it and buying from Crucial, which guarantees this one.

I'm aware of that with the OS, but I was actually referring to the architecture of the CPU itself.

At any rate, I hope you get your hands on RAM that will work for you.

The computer's specs say 2GB max, and a 32 bit bus will support 4GB, assuming a 32 bit processor uses a 32 bit address bus.
Kingston said it's something to do with single rank vs. double rank modules. I've never heard of this before, but it is a real thing and I assume this is the problem since everything else matches.
