I just bought two OCZ 1 GB DDR2 800 sticks from Tigerdirect and when I popped them in only one shows up. I originally had two Corsair XMS 1 GB DDR2 800 sticks and both of them showed up and were in dual channel mode. This new memory is also dual channel so I should have a total of 4 GB of ram but when I right click the computer and look at properties it only shows 3 GB and DXDiag only shows 3070 MB. Is there anything special I'm supposed to do to get it to show or does this mean one of my sticks might be dead? I have an EVGA 750i FTW motherboard and I'm using Windows XP Professional Service Pack 3. I know Windows will recognize up to 4 GB so I don't get it. I have another PC I could test this memory on, just didn't want to go to the trouble. Oh, and I have an X1900 XTX with 512 mb of ram if that matters.

You will only see 3.xGB if your using 32-bit Windows. IIRC, 32-bit Vista will still show 4GB in the welcome center/info, but will still only address some 3GB of it.

To actually make use of all 4GB, you need a 64-bit operating system. As long as your BIOS is reading 4GB, there is nothing wrong with your ram. Or, run CPU-Z and see if it is detecting all four sticks.

Ah, I forgot about CPU-Z. I ran it and it shows 4096 MB of ram so they're all working. I plan to be upgrading to Vista soon (Have the disc already for 32 bit) but doesn't 64 bit have lots of drawbacks? I have a Core 2 Duo so I can support 64 bit but I just recall people saying it has program compatibility issues and everything has to be special made for it.

Now that 64bit is starting to get some more support things are working alot better with 64bit than before. You should be fine with a 64bit OS.

Vista 64-bit is pretty good with compatibilty from what i hear (i don't have it myself, but plan on getting it soon). I know a few here use it, and most have good things to say about it.

The only thing is that, IIRC, it requires digitally signed drivers for your hardware. But, from what i've seen, that can be disabled.

Hmm, that really makes me wonder then. I already have a 32 bit copy of Vista Home Premium. How much does the 64 bit cost over the 32 bit?

Looking at Newegg, they seemed to be priced the same for the OEM versions, or you can get the Vista Ultimate retial pack that includes both the 32 and 64-bit versions.

If you can get a hold of the 64-bit DVD you can install it without needing a new key.

So if I install 32 bit, can I just pop in the 64 bit later and tell it to install or does it require something special? Why does it require signed drivers for everything anyway?

I'm pretty sure you can just do a format and install the 64bit with the old key. If you can borrow the disk from someone go that route.
