More RAM with win8?
I like XP. I like it a lot. But....
The only real problem I have with my computer is that, though Firefox
says you can open as many tabs as you want, after about 40 or 60, I get
a message from AVG saying I've used a gig of memory. And later, FF and
also Sea Monkey, will crash. I've tried to cut down the number of tabs
I open, but I'm hooked. I've got a monkey on my back.
AIUI, XP can only use 3 of 4 gig I have, and with win7 or 8, you can
have 8 gig and it can use more than 3. Maybe 7? Would that let
me open many more tabs?
If so, this is as of now the only reason I wouldn';t hate it if I
somehow hads to move to win8.
This is only for my home computer. For the netbook, I don't do real
work there, so I've never had anything crash iirc.
My experience with WinXP x32, and without the /3GB switch,
is a single application can get around 1.8GB before
something complains. (The kernel user split is 2GB/2GB,
but the program needs a little space for code, so the
limit works out to 1.8GB of user space or so. In my testing
below, I managed to get 1.9GB.)
Using the /3GB switch in boot.ini is a possibility, but then the
application itself must be "large_address_aware" to use
the extra space. I wrote a "five line C program" to test that
stuff out, and I was able to get a 32 bit application to use
a bit more memory. It means a second application is
going to get less memory (and run at normal speed), or
you'll drive the system into paging country, which is
only fun if you have an SSD or similar high-performance
storage for pagefile.
It sounds like AVG is spoiling your fun, and
some monitoring function should be switched off.
AVG is pulling the plug, before the fun has even begun.

I tested memory limits, in this posting...

Normal conditions x32 OS
So-called 2GB kernel/2GB user split.
1919 MB (of 2048max) acquired by a simple memory-grabbing program.
Using /3GB boot.ini flag, plus LARGE_ADDRESS_AWARE set on the .exe
2828 MB (of 3072max) acquired by a simple memory-grabbing program.
Switch to 64 bit OS, run 32 bit test program with large address aware set.
3822 MB (of 4096max) acquired by a simple memory-grabbing program.
Switch to 64 bit OS, 64 bit program... (not actually tested, too lazy)
Pretty well all the memory, except what the OS uses. On my
8GB machine, I might have seen it go to at least 7GB in an
unrelated test. Note that not many browsers are available as
64 bit applications.
AVG is shortchanging you.
I don't have any "normal" applications which had LARGE_ADDRESS_AWARE
bit set. It was easy enough to do though, for my testing purposes.
It's just not something they'd think of doing to release versions,
as there are some performance caveats with using /3GB. Like running
out of "Pool" a little earlier.

Like any good rocket ship, the AVG preferences has a
wealth of stupid settings. There is a tick box to
get that warning to go away. No telling what warnings
you might lose though.
