Cool .. Not a bad price either. I'm still good to go on the hard drive setup for now.

I would really just like to get the ram working right.

Thanks

Thanks

edit your boot.ini and add /pae /nolowmem /noguiboot

Cenatek has software that allows you to use the extra 2GB as a ram disk. All data is transfered to and from the Hard Drive to RAM on boot and shutdown, be sure to be using a good ups with a nice runtime if you use this software.

Have you tried turning off the swapfile? See if that changes the ram available.

You cannot turn it off in Windows 2000/XP. You need it set to a minimum of 4GB, there are boot switches you can use to minimize Windows usage of the Swap File but it is needed for debugging should the computer crash due to a bad program, bad driver, or Operating System Fault.



You have not told us what kind of Motherboard you have? Who made it? What Model is it?

Will the switches work by themselves or do I have to pay $50 bucks for that software.

Thanks Allot

Maybe vista will have this fixed but we can only hope.

DFI "LANPARTY UT nF4 Ultra-D" NVIDIA nForce4 Ultra Chipset Motherboard (3/16/2005 BIOS)

Is the memory you are using listed on the DFI web site as a Module that has been tested for compatability? If so then the Ram you are using might be the problem.

I doubt this will work but you can relax the memory timings to something like, 3-3-3-10 and see if that helps. (doubtfull)

The ram worked flawlessly at 2 gig. OCZ is supposed to be one of the best. And when I built the system It was the best performer and if I remeber correctly the only vendor I could find with 1 gig matched dual channel specs. Some info I got at DFI was becasue it was 2 sided I wouldn't be able to run at full MHZ with a Winchester core CPU. Which is fine. I plan on upgrading the CPU eventually anyways.

I just would like to have windows utilize the full 4 gig.

Seems to me that if it was SP2 that disabled it there should be a way or tweak to reenable it. From what I read it was because of security reasons. I have confidence in my skills to deal with that on my own. Just would like to have the rest of SP2 installed. So I need to just undo the one so called fix that SP2 installs.

Thanks Again

Oops .. Just updated my BIOS also so "DFI "LANPARTY UT nF4 Ultra-D" NVIDIA nForce4 Ultra Chipset Motherboard (6/23/05 BIOS)"

Why do you need 4gb of RAM? It's a waste....

Heard the same thing when I got 4 meg of ram

I believe you found the answer to your question. Four Double sided DIMMS usualy do not work well in a lot of motherboards. At this point if you want more than 2GB buy a server motherboard or ABIT's UL8 motherboard. Both handle double sided DIMMs rather well.

Not a answer just a alternative..

Common you guy's .. This can't be that tough. If Windows XP Pro SP1 recognizes the full 4 gig and SP2 disables it .. There must be a way to undo the specific patch that causes this without disabling ALL of the SP2 patches.....

If you have 3dmax you need at least 2 gigs to do mid poly models .

It appears that the big difference with SP1 and SP2 is that DEP is enforced by hardware and software in SP2.

The /AlwaysOff switch may fix the DEP problem and allow you to actually use the ram. Most of the tech notes mention Intel processors only. I'm not sure how PAE applies to AMD based 64bit, even if it is DEP supported. Turning off DEP may leave you open to code exploits due to the nature of the protection.

Now we are cookin.. With the built in AMD Antivirus stuff and running a secure system as I do with firewalls ect. I'm not concerened about the code issue at all. I also do allot of backups.

But I've tried a bunch of switches in the boot.ini and haven't had any luck?

Any suggestions?

OK.... This has been killing me for some time now....

I recently built a custom machine running 4 Gig Kingston DDR2/533 and we all know the story. BIOS reports 4 GIG but XP Pro reports 3.0Gig. My question is very simple....

A few weeks ago I was looking up this same topic and I saw a posting on another forum (I cant remember the site) in which somebody stated that If you install 4 Gig in Windows XP the machine will only perform as if 512MB (or around there) is installed.

Now I know what you all are probably going to say and frankly I'm hoping you say it because this was the only place I saw something like this posted and I havent been able to get it out of my head since.

Is windows using the entire 4Gig for SOMETHING? Is having 4Gig installed actually doing more harm than good???

Please put my mind at ease so I can say that I built myself an incrediable machine without thinking I overlooked something horrible.......

Thanks,
Jim

Jim,
I tried running 2 gig at PC Pitstop then Ran the same test with 4 gig and the results came back the same .. the scores were identical. So I doubt it's hurting to run all 4 gig. I'm still working on it. Will let ya know if I come across anything.

Here's a question" If we are running dual channel and you need matched pairs to run dual channel .. How can we be running Dual Channel with only 3 gig showing up?

Livin on the edge I guess. but Oh well .. My system runs as well if not better with all 4 gig but I must admit the differance isn't what I was hoping for.

Good Luck

To bring this back.. heres the intel chart on why your pc can't use 4gb
