Does anyone have luck with 3.25 GB of memory on a P5Q-E Motherboard or do you have to get the ASUS P5E3 Deluxe for 3.25 GB of memory on 32 bit? I know that the ASUS P5B-E only shows up as 2.93 GB and requires enabling memory remap for 64 bit to detect all 4 GB of memory.
Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie. Hi I'm Maddie. Hi I'm Maddie I'm a beautiful black flower,

Maddie, didn't you already have that question answered in a previous post? You are getting too hung up on a half a gig of RAM. If you really need that much RAM to operate whatever you are running then you should install a 64 bit OS.
Concentrate on the other features of a MBoard. I believe jam gave you some suggestion on what chipset to look for. Then just choose a board with the feature set you need. Bingo, board selection is done.

Maddie, in your other thread, I tried to explain how the 4GB of virtual address space (VAS) works. Do you have a 256MB or 512MB video card? The card's memory has to be mapped to the VAS as does several other hardware components (controllers, PCI cards, BIOS). Everyone of those items MUST take a bite out of the 4GB VAS. If the full 4GB is occupied by physical RAM, the RAM is forced to surrender some of that space to the other components.
Do you have another video card you can try temporarily? If you currently have a 512MB card & your RAM is being recognized as 2.93GB, try swapping it with a 256MB card & see what happens. That 2.93GB *should* increase to about 3.2GB. And make sure to disable the memory remapping option in the BIOS...it should NOT be enabled when running a 32-bit OS.
I have a feeling this is another post by Maddie:

I don't want to install a 64 bit, its a piece of junk. 1st, you can't game and 2nd, it doesn't run software properlly like 32 bit.
I don't understand why you would not help me. I also don't know why so many other people have 3.25 GB and I only have 2.93! I only have a 512 Video Card and a Sound Blaster Audigy 2. Please Tell me weather the better motherboards would solve my problem.
Oh and please don't compare my post to other peoples posts. That yahoo post is NOT me.

I know I don't have a problem. I am asking why I am not getting 3.25. I used different computers with 512 MB of Video Memory and they have 3.25. I am pretty sure its because of the motherboard and I think I am going to get something better, like the ASUS P5E3 or the P5Q-E because this P5B-E is a really bad motherboard, but if you are unsure, thats fine. Again, I am sorry for annoying all of you with my repeated questions.

"I don't understand why you would not help me"
We can't help you because there's nothing wrong! Try my suggestion...remove the 512MB video card, temporarily replace it with 256MB card (or even a PCI card) & see what happens to your RAM total.
"I am asking why I am not getting 3.25. I used different computers with 512 MB of Video Memory and they have 3.25"
You answered your own question - because they are "different computers" with different hardware configurations. Here's another explanation of where that memory goes:
The PCI memory addresses starting down from 4 GB are used for things like the BIOS, IO cards, networking, PCI hubs, bus bridges, PCI-Express, and video/graphics cards. The BIOS takes up about 512 KB starting from the very top address. Then each of the other items mentioned are allocated address ranges below the BIOS range. The largest block of addresses is allocated for today’s high performance graphics cards which need addresses for at least the amount of memory on the graphics card. The net result is that a high performance x86-based computer may allocate 512 MB to more than 1 GB for the PCI memory address range before any RAM (physical user memory) addresses are allocated.

No, it's not, but if spending $100-200 for another motherboard will stop you from constantly posting about the same subject, please go out & buy yourself a new board!

Sigh...
"I don't want to install a 64 bit, its a piece of junk. 1st, you can't game and 2nd, it doesn't run software properlly like 32 bit."
64-bit is not a piece of junk. The only program I have that won't run under Vista-64 is Adobe Premiere Pro CS3. It is the one program that keeps me from dumping my XP-32 partition. Everything else runs fine. Even the really old games.
"I also don't know why so many other people have 3.25 GB and I only have 2.93! I only have a 512 Video Card and a Sound Blaster Audigy 2."
Every system is different. If it makes you feel any better, XP-32 only recognizes 2.5GB of my RAM (I have two 640MB videocards). But under Vista-64, all 4 gigs are recognized.

Alright thanks for the responses, I did not mean to annoy all of you, but you already answered my question partly. Here is what I think based on your responses, the ASUS P5B-E has too much stuff it maps, I don't even know how to stop a lot of stuff from mapping, like I don't need the network card and the sound card since I ALREADY have a network and sound card seperate from the motherboard. I will also test a PCI video card and remove the 4870 to test the RAM amount, but based on the ASUS P5B-E Manual, it said it only goes up to 3 GB of Memory so I think its strictly the Motherboards Fault. I am asking if other motherboards would have this restriction.

"you already answered my question partly"
Partly? No, it's been fully answered, in both this thread & your other threads on the same topic.
It is NOT the motherboard's fault, it's the hardware you have installed! Why do you need a separate sound & network card? 1st try the video card experiment & see what happens, then try taking out the two cards & see if they have any affect on the RAM total.

I have a question for BFM.
Putting aside the question of how much system ram your system shows compared to other people's systems, Are you able to run your applications/games with acceptable performance in the current configuration? If the answer is yes then the rest is just a pissing competition and it's time to move on.

Ok, I tested the Video card thing and I put a NVidia 128 PCI into the system and removed the sound card. It shows up at 3 GB of memory instead of 2.93 GB. I've used an HP Workstation with 256 MB of Video Memory which shows up as 3.5, which means, if I put my 512 Video card into that computer, it will show up as 3.25. It is definitely the Motherboards fault now. Thank You for misleading me and you are just going to come back and say you already answered my question, when you really are not.
All I am asking is Which Motherboard will 'not' have a 3 Gigabyte limit, so that I can freely install my 512 MB video card and get 3.25?
The whole reason I want a different motherboard is actually because I want to get PCI 2.0 performance because my friend told me to get another motherboard since I have a 4870 Video Card.
I am also thinking that my motherboard is having a 3 GB limit and is only giving me 2.93 just because I have a 512 Video Graphics card and I don't want that, I want to be getting 3.25 GB since I have a 512 MB Video Card.
So you keep telling me that I am posting the same question, but you are not giving me a straight answer. All I am asking is what motherboard will give me 3.25 GB of RAM for a 512 MB Graphics card, NOT 2.93 GB. I am also asking weather a P5Q-E is one of them.
Other than the sound card, which really never made a difference, there is NOTHING installed in my system other than 2 hard drives and 2 cd rom drives. There should be no reason why I should be getting less than 3 GB of memory.
Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie. Hi I'm Maddie. Hi I'm Maddie I'm a beautiful black flower,

Hey Good News! I found that the ASUS P5K allows 3.25 GB of Memory on 32 bit! It has everything I need for a good price.
However,
Its not PCI 2.0, but I really like the ASUS P5Q-E, so does that motherboard have a 3 GB Limit?
Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie. Hi I'm Maddie. Hi I'm Maddie I'm a beautiful black flower,

Please, just go out & buy another board already. Because spending close to $300 to *possibly* get an additional 256MB recognized & the extreme speed advantage of PCI-e 2.0 over PCI-e 1.0 is well worth it!

I'm just getting the P5Q-E since its cheaper. They said that the P5Q-E will not have the 3 GB limit and will give me the full capibilities of my PCI 2.0 Video Card.

Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie. Hi I'm Maddie. Hi I'm Maddie I'm a beautiful black flower,

I was being sarcastic.
You will see no difference between PCI-e 1.0 & PCI-e 2.0. And even if you do pick up an additional 256-512MB by swapping boards, you will see little or no difference in performance there either. Is it worth $150? Would you pay $150 for a 256MB stick of RAM? I hope not. And hopefully you realize that you will have to re-install Windows & all Windows updates due to the new board?
One thing I don't recall anyone asking - have you ever updated the BIOS? Do you know which version you're currently running? There have been quite a few revisions over the years. Maybe the latest fixes your "problem".
IMO, what you're doing (or about to do) is a complete waste of time & money.
I still think this is you:

You will see no difference between PCI-e 1.0 & PCI-e 2.0.
^ My friend disagrees and there is an obvious reason, the fact that the PCI 2.0 is the next version up from the PCI 1.0.
One of the main reasons I want to upgrade my motherboard is because It does not support 32 and 64 bit dual boot. I have to keep enabling memory remap just for a 64 bit operating system to detect all 4 GB of RAM. Unless there is a tweak in the motherboard option, its a pain to keep switching and I heard the newer motherboards won't have this bug.

^ No it isn't and coincidently, that answered my question and that is why I came back and said I am getting the P5Q-E Motherboard. Sometimes other people can copy other peoples questions and answers you know.
About the 256 MB extra memory, at least I would have more for extra virtual machines which at least are 128-512 or maybe 1 GB each.
Besides, my motherboard is old, like maybe this is why it doesn't go beyond what I have and has limitations. I honestly should have considered getting a new computer if my system wasn't that obsolete.
Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie I'm a beautiful black flower, Hi I'm Maddie. Hi I'm Maddie. Hi I'm Maddie I'm a beautiful black flower,

You are going to get an ulcer worrying about the lost RAM when it doesn't make a bit of difference in the real world.
As far a PCI 2.0 goes, that is simple an incremental improvement. I guarantee you won't be able to tell the difference. But, as jam said, go spend your money. Need to stimulate the economy anyway.
Finally, I have not played with memory mapping but I am pretty sure that is OS dependant. If you use Windows dual booting I think each OS will configure ALL hardware the way you set it up in that OS.

"My friend disagrees and there is an obvious reason, the fact that the PCI 2.0 is the next version up from the PCI 1.0"
This thread has probably peetered out but I'd love to see proof of your friend's claim. While I agree that 2.0 is the latest version of PCI-e, the chance of you seeing any performance difference because of it is slim. Like I said, it's not a worthwhile reason to upgrade & neither is the RAM issue.
BTW, if your friend is so knowledgable about computers, why do you bother posting in these forums? Why not just ask him (or her)?
The major difference between PCIe 1.x & PCIe 2.0 is the doubling of the available bandwidth from 2.5GT/s (Giga-Transfers per second) to 5.0GT/s. If your card isn't being bottlenecked by the PCIe 1.x bandwidth, performance will NOT improve by moving to a board with PCIe 2.0. Didn't your friend tell you that?
