Install 4GB into laptop whose manufacturer claims 2GB as MAXIMUM

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"
(Autodesk Inventor2010 Profressional with assemblies over 5,000 parts,
Agilent ADS RF simulation suit - wants quad core, 8GB)

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.

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

Technicalities? Is that always your response when you say something
that's wrong and you get corrected?

If that was the point you wanted to make, it should have been what you
said. What you said ("There is a max 3 GB RAM for any PC which has a
32 bit CPU or a 32 bit OS") was *not* correct, and I simply pointed
out the correct thing.

Moreover, the thing you now say ("you can't use 4 GB RAM unless you
have 64 bit hardware running a 64 bit OS") is *still* incorrect. It
applies only to *Client* versions of Windows, as I said. You can use
4GB of RAM, and more, with some 32-bit Windows Server operating
systems.

Even if you have 64 bit hardware running a 64 bit OS, odds are
you won't be able to use all 4GB, unless you're running a 64 bit
application. Most 32 bit applications can't use more than 2GB
of address space, and the ones that are large address aware
can usually only use 3GB. The OS may use 100 - 200MB above
the 3GB division. Photoshop Elements 6 & 7, 32 bit Photoshop
CS4, and MS Flight Simulator X with SP1+SP2, are some apps that
are large address aware.

Using PAE hardware and PAE aware software (Page Address Extension) one
can address up to 64gb of RAM with a 32 OS. Several MS server versions do
that - so does Linux.

Your failed Corsairs are likely to be "ValueSelect" made in Taiwan
I never buy these, I only buy VA-series labeled "for Mac" but in fact are
dual-purpose (ANY Intel machine, be it PC or Mac).

For example a regular individual will use Corsair or vendor (I like
ZipZoomFly.com) memoryconfigurator and find fo rmy HP laptop this:

VS1GSDS667D2 or something like that. Sorry to brag, but I go deeper.
I will construct a part# as VSA1GSDS667D2
Just one letter makes a huge difference, the regular sales idiots have no
technical background and no understanding what A stands for, they see one
thingL
APPLE MAC memory and immediately claim it's a wrong choice.

Nope, this memory works in PC's and is made in Colorado, USA; whereas VS
series = Value Select is a nongaming onCAD regular memory made in Taiwan.
The rest of part# is identical.

But I swear VSA* part is highly unlikely to fail, we've been using them in
really hot high-speed environment.
I contacted Corsair explaing this must be marketed to both PC and Mac but
while excellent engineers, these people dont know marketing.

So they lose to cheapies from Kingston, and horrible PNY. Sorry for PNy
which is made in my homestate New York.... nothing comes close to VSA
series.

The next higher step is CG or something like that series, but I can't use
those in a laptop, they com ewith heat sinks and usually for desktops

As you can see the same Corsair comes in different shapes, you probably got
a cheapie, my 2GB cost $80. You could buy SEVERAL 2GB module sfor these
money if it were value select

You're running Server, and Server has the PAE extensions, therefore
it can use more than 4GB by paging. I wasn't talking about OS's. I
was talking about the memory use capabilities of 32 bit applications.

If you are running multiple applications they can use much more than 4GB
combined.

Why do you think PAE mode is that much slower than 64bit mode?

 

Hey,

Whck what "Agilent ADS" CAD/EDA package recommends for best performance (I
used to use it for RF circuits design, but switched to much betetr AWR
MicrowaveOffice2009):

They recommend Quad-core processor & 8GB memory.
You can never satisfy these hungry software makers, they WILL use all
avaialble resources and complain.

This is in part due to Capitalist system where one industry stimulates
another, they want 8GB, so you go buy mor ememory, and amemory maker ends up
making profits as a byproduct of an Engineering company making software.
Same with Windows - Microsoft stimulates more powerful PC sales.

I am NOT saying it's bad, for the simple reason humanity has no better
social system to offer yet. Twenty years in USSR taught me what happens
when government regulates hi-tech --> it becomes LOW TECH & INFERIOR to the
West!
But it's just bad on environment - endless cycle of increasing consumption.
I think 8GB memory is a catastrophically large amount LOL! Back in 1991 we
bult Z80-based mcirocomputers where entire GUI & OS and some games fit into
32KB memory.

 

Your're not running Windows client!!
Your OS is a Server using memory extensions which are SLOWER, well it's
really slower, than true 64-bit OS.

Get educated!

 

AdobeCS4 is what I use here.

But I got much larger monster you guys probably never heard of, which can
use 12GB (TWELVE GIGABYTE) memory:

AgilentADS2009
Autodesk Inventor2010 Professional simulation assemblies w/over 5,000 parts
and running FEA Stress analysis.
AWR MicrowaveOffice <--love it, best RF circuits design suite ever!
Cadence Allegro or Orcad16.2

And so on....
