[QUOTE="mojahid_1st"] I don't appreciate you calling me a liar. If i am wrong you can simply correct me, but to dafame[ sic ] my character by calling me a liar is plain wrong. You should consider your forum eticate[ sic ] before posting.
Also, 8gig of ram is still a waste of money regardless of wether[ sic ] or not 64bit OS can recognize the ram. The money is better spent on a better Mobo, GPU or CPU.

The fact that you're incapable of proper grammar suggest to me that you're incapable of realizing your own errors. And if we are to evolve this place from a cesspit of 4-year-olds, then one should learn not to spread misinformation and FUD around. I said that your statement that "no OS would recognize greater than 4GB" is a flat out lie. Windows Server edition OS's have been able to support greater than 4GB from the start with NT server; that is largely due to the fact that most of the Server editions that can recognize that much memory are usually the kind that are meant to support a minimum of so many CPU's, and thus each would have separate memory controllers to address varying amounts of RAM. Linux has supported greater than 4GB of system RAM practically before we even moved to 32-bit CPU's, given its inheritances from Unix, which had servers with 4GB of RAM back when 128MB of system RAM in a home computer seemed astronomical (i.e. Windows 95 era). Hell, if you were so inclined now, you could buy a Cray with up to 4096 multi-core CPU's (IIRC, the X1 which used about this many Opterons can be had in a flavor that has about that many quad-core Phenoms), and likely several Terabytes of RAM. Back to home/workstation OS's though... 32-bit Windows and Linux were limited to 4GB of addressable memory, and without being able to enable PAE, some of that memory address space is reserved for I/O addressed for hardware devices connected, and sometimes a 'local cache' of addressed for your vRAM. What PAE is supposed to do is then take the extra bits of address space that a modern CPU would have, and do some hardware magic to have those reserved I/O addresses instead go on the .5GB or so of addressable memory after the initial 4GB of addressable memory space - thus the result is that an end-user on a 32-bit OS can see and use all 4GB of system RAM. However, in order to be able to enable PAE, you need several things: - a PAE-supporting CPU (all 64-bit x86 CPU's do so by default, but there were some 32-bit CPU's that did, too) - a motherboard chipset that supports PAE - said motherboard must also employ a supporting BIOS with this functionality, as a lot of the I/O addressing would have to be done at the BIOS level anyway - an OS that supports PAE (Windows 2000, XP, Vista, or any modern Linux distro) - device drivers for your hardware that support PAE You could have all of the other things, but if any one of these do not support PAE correctly, the OS then kicks in a fail-safe to prevent crashing and disables PAE, limiting you again. And for many, the part preventing PAE from functioning as it should is the last part - the drivers. You would think by now that driver writers would at least add in a PAE-compatible path or code for their software, but the reality is that many don't even bother in a 32-bit OS driver. Thus why we have to suffer with not being able to use all 4GB of memory for ourselves :evil: :cry: Vista Home Basic/Premium (64-bit) are market-limited to 8GB of addressable space, while Business and Ultimate (64-bit) are able to address up to 128GB of memory. Most Linux and Mac OS X (at least in the software side) are configured to support the maximum physical amount of addressable memory, which is somewhere in the order of 1200 petabytes. Though realistically, finding motherboards that can support a lot of RAM and high-density RAM sticks for the job is another matter entirely. I can guarantee that the first systems to even start reaching the limit of 64-bit addressing will be in the supercomputer/HPC segment, and it will be quite a while after that before end-users have to even remotely start thinking feasibly of a system that could have petabytes of RAM - we're not even near having hard drives or file systems that can support petabytes' worth of storage yet. :lol:wow you found 3 spelling mistakes..... good for you *thumbs up*
The fact is, the original poster wanted to know how much memory he is getting, I answered that, and added an opinion which was partly backed by some incorrect information to which I take responsibility. Your reply to my post, although very thorough, is completley off the topic.
"I said that your statement that "no OS would recognize greater than 4GB" is a flat out lie "
This is where i have an issue, you are obviously well learned in this area, and i respect that, however my statement was not a "flat out lie" it was "flat out incorrect". I can handle being incorrect as that is due to misinformation and i can eventually educate myself, as you have obviously educated yourself.I cannot tolerate being called a liar as I did not intend to milead anyone. You called someone else a liar in this thread also, maybe while you are reading up on the many different OS's you can also work on your people skills?
