Everything you say is correct except your paean to memory manufacturers.
As memory prices have dropped the percentage of defective brand new ram
sticks, regardless of cost or manufacturer, has risen.
Sadly brand name does not guarantee working RAM. I have had recent failures
of new Mushkin and your beloved Corsair ram sticks.
The same seems true of hard drives, possibly worse than RAM, as hard drives
are more complex to assemble. Fortunately hard drive manufacturers actually
honor their warranties. RAM manufacturer warranties are something else.

Yes

When they say "max 2 GB RAM", they mean the RAM types supported by the MB
only go up to 2 GB for the total amount possible from the number of chips
possible at the time the PC is released. If they later release a larger RAM
chip of a speed that is compatible with the MB, the max possible RAM for
that PC increases, and they will not likely update the specs.

There is a max 3 GB RAM for any PC which has a 32 bit CPU or a 32 bit OS.
This is remotely related to Vista, since there is a 32 bit Vista and a 64
bit, but this should probably be discussed in a hardware specific forum.

Now as an Electrical Engineer I proved this point and upped my HP to 4GB
w/3.25GB usable:


If your chipset is Intel945 - as in my HP dv8408us & MANY NEWER HP laptops
(Pavilions/MediaCenters), ignore HP claim of maixmum memory = 4GB.

You can install 2GB+2GB sticks, you'll get 3.25GB usable by Windows, I know
you waste about 1GB but it still makes sense. Intel945 chipset is hardwired
for 32-bit adddresses so Windows whether it be 32 or 64bit is not a
limitation, it's the chipset which is a limitation, STILL it can address
4GB, not 2GB as HP claimed on my laptop specs. I've done the same with IBM
Thinkpads, where they claimed 512MB to be max 5 years ago, but I was running
with 1GB. It appears idiots sometimes write these specs because 2GB laptop
SDRAM modules were unavailable at that time at reasonable price/pinout?

By the way if your Windows is 32bit - that is a software limit at 4GB,
chipset - is a hardware limit. Th eoverall system limit is obviously
SMALLESt of these numbers.
The only way to use over 4GB is if both hardware + Windows are 64-bit, AND
BIOS is updated.
Also the trick above may give you BLUE SCREEN of DEATH if your HP laptop
BIOS is not latest, and you never get full 4GB due to memoryhole in older
laptops, and I/O overhead which wastes 0.7GB

I use strictly CORSAIR memory - not their Valueselect series, but regular
Corsair - made in Colorado, CA, world's top speed/US-designed/US-made maker,
with their valueselect line outsourced to Taiwan but regular still made in
USA. This is in the same class as QCZ & Mushkin, etc but made in USA with
all premium manufacturing/semiconductors/quality. They continue mislabel
some SDRAm modules as "for Mac", but they're dual Mac/PC since Apple is
using Intel chipsets now, that is one problem with Corsair they didn't
listen to my complaint and lose revenues when nontechnical people don't
realize what Corsair labeled as Mac, is for PC.

So 3.25GB here on a laptop claiming to be 2GB max. I can appreaciate extra
1GB+ (55% increase!) for CAD & Engineering simulation wares som eof which
list 8GB as 'recommended"

PAE enables the use of up to 64gb with a 32 bit system. Several MS server
OSs have that capability as well as Linux. It is true that there is still
a limit of 4gb per process.

Sorry, this is not correct, for a couple of reasons.

All 32-bit *client* versions of Windows (not just Vista/XP) have a 4GB
address space. That's the theoretical upper limit beyond which you can
not go. Please note that this is for client versions only, not
servers.

But you can't use the entire 4GB of address space. Even though you
have a 4GB address space, you can only use *around* 3.1GB of RAM.
That's because some of that space is used by hardware and is not
available to the operating system and applications. The amount you can
use varies, depending on what hardware you have installed, but can
range from as little as 2GB to as much as 3.5GB. It's usually around
3.1GB. Please note that this *not* 3GB, but an amount that varies,
depending on the computer. It's *usually* a little more than 3GB.

Note that the hardware is using the address *space*, not the actual
RAM itself. If you have a greater amount of RAM, the rest of the RAM
goes unused because there is no address space to map it to.

No wonder you've been unemployed for months now.....

AutoDesk Inventor sucks.....The industry standards for solid modelling is
Solidworks or Pro-E.

Microwave Office is much more popular than ADS also.

This is what happens when posters edit someone else's post or an article and then
try to put it in their own words and terms and having no clue as to what they are
saying or what it means. :-)

Yep, that's what sometimes happens.

Technicalities. Point is you can't use 4 GB RAM unless you have 64 bit
hardware running a 64 bit OS.

Were your failed Corsairs ValueRam serie smade in taiwan, or premium made in
Colorado/California, USA?

Besides stupid consumers demanding cheaper & cheaper & government alalowing
upto present deceitful advertising, harddisk failure rate has risen due to
fundamental physicis - specifically Quantum Theory which is starting to play
role as magentic domains have shrunk to molecular level... not yet, bu tat
nanolevel already. There're other storage mediums on the horizon to resolve
this Probabilistic behavior which is replacing deterministic behavior of
older, lower capacity drives.
