I'm trying to think... For one that wants to dual-boot XP x32, and Vista x64, what amount of memory would compensate between the two OSes? I was thinking about 3GB DDR2 800, since I only have 2GB, but willing to add at least 1GB more to compensate, but would this be about the "go between" amount between the two, should dual-booting be something to look forward to?

You should be fine with 2 gig.

Hopefully it won't bottleneck on Vista x64's MCE, tho. However, I'll take your word for it. Since Hauppauge built the HVR-1800 to be Vista certified, then it should probably get some fairly decent results in both OSes.

You'll be fine with 2GB but since x86 maxes out at 3GB with the switch, and x64 can go much higher, and because you usually buy ram in 2GB pairs these days, you might as well go with 4GB since x64 can use more and x86 just won't use the last GB of that.


You could go with 3GB sure, but as I said it seems to be easier to buy ram in 1GB pairs these days, meaning another 2GB.

The /3GB switch, like I said, lol. It's a complicated issue...


Read the 3rd paragraph here (also applies to Vista x86):

And then for some real fun regarding virtual addressing, physical memory, kernal virtual address space, etc... Read the various entries here:

To make things easy with 4GB or more of RAM, just use an x64 CPU and x64 OS
