- Doomhammer, on 10/12/2007, -0/+0The 32-bit Linux kernel, v2.6.*, can support up to 64GB of RAM.

CONFIG_HIGHMEM4G=y
or
CONFIG_HIGHMEM64G=y
Not really a "tweak" with xconfig or menuconfig. - Doomhammer, on 10/12/2007, -0/+0Yes, I suppose it really does depend on your definiton of "tweak". When building the kernel, compiling in high memory support, IMO, is not a tweak.
- xdigitalkill, on 10/12/2007, -0/+0I always remember windows being able to use up to 4 GB, but 64 bit machine can handle up to 16777216TB ram(i did this rather quickly with a calculator so it might be wrong and probably is)but anyways 64bit can handle about however much ram you can afford to throw in it
- 7of7, on 10/12/2007, -0/+0Suddenly I want to put another GB in my laptop. Though I'd have to buy 2GB and try to sell off my 2x512MB in an effort to recoup my costs.
- Otto, on 10/12/2007, -0/+0He's also wrong. A well-written 32-bit OS should be able to address 4 gig, not just 2. That's if every bit of the OS has address pointers treated as unsigned long's like they should be.
- AT0MIC, on 10/12/2007, -0/+0Wouldn't that be tweaked?
- dconlon, on 10/12/2007, -0/+0One-line sentence from the article that summarises it:
"...vendors are starting to pitch 1 GB memory modules for the PCs, which in pairs give you 2 GB capacity, the maximum a 32-bit OS can address without tweaks."
