RAM here, but not here

[paladin]

I just added 2 gigs of RAM to my computer, I checked everything in the bios 4096mbs. But when I check the specs from the desktop and from the windows start center, it shows you specs, it only says 3 gigs? I cant figure out why? Any suggestions?

Windows 32 bit can't detect more than 3. When I had 4 gigs in ym rig it would cause a BSOD withing 24 hours of each startup. Either upgrade to Vista 64 bit or remove the 4th gig.

[ImSpartacus]

yeah, 32 bit os's cant use more than 3ish gb of ram. just stick with 2 (for dual channel and 1t command), or get a 64 bit os like mr m1337 said.

[Kybo_Ren]

Not true... Some 32-bit OSes have difficulty addressing more than 3 GB of RAM because they were designed poorly, while others can address the full 4GB.

Either way, upgrade to a proper OS.

What 32bit OSes support 4 gigs? None of the windows?

Can't Vista 32bit support more than 3 Gigs? I might be wrong (and I probably am).

You're wrong. :)

I hope I'm not wrong... or else I just looked like a complete idiot!

The Windows server 2003 editions support a whole mess of RAM depending on the version. Enterprise edition supports 8 CPU/64GB RAM or something crazy. Google it for more info.
That's a 64-bit OS (that can address 64GB, there are x86 versions) :)
Well, it can do eight-node clustering and therefore 32 GB in a 32-bit OS, but the 64-bit version will address up to 1 TB of RAM.

See?
It's possible. Poor design just makes most common 32-bit OSes (read: Windows) crap out when there's more than 2 GB of memory. It has to do with how the Windows Memory Manager handles memory internally.

Ok Thanks guys. I just ordered the 64 bit version. Thats stupid that it only supports 3. On Microsoft's website it says the 32bit version supports up to 4 gigs? Any idea if that true or how to do so?

Any 32bit OS should be technically limited to no more than 4096MB of memory because any memory address higher than that would overflow.

[Kybo_Ren]

It wouldn't overflow... It just wouldn't exist.
And take note of the "should be"

[Kybo_Ren]

I know. He just asked about any OS that support it though. :p
Semantics :P

You also might wanna check the RAM clock...you probably fucked it up unintentionally.

The RAM clock has to "sync" with the processor speed...you might wanna post RAM stats and CPU stats if you don't know how to check yourself.

It doesn't have to. How do you think people overclock with low end memory.

Well actually it HAS to sync...it calculates and reduces the clock automatically for you.
