/3MB Switch Not Working In XP on a UD3R

[2therock]

Just got a UD3R up and running on XP Home. I have 4GB RAM 2x2GB on it but it only shows 2.5GB.

The same HDD on the old Gateway Mobo showed 3.5GB.

I did the /3MB switch but she will not show more.

There is a part in the line (/fastdetect) I'm not sure about see it here:

multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows XP Home Edition" /fastdetect /3GB .

The GPU is a XFX GeForcw 8600GT.

Thanks

How much MB ram is on that PC's GFX Card?

And you want to use /PAE not /3GB >>>

also look for memory hole remapping or some such in the bios and change it. It sometimes messes with memory limits.

and the /3GB is a switch that allows each windows program use 3GB. The default is 2GB and if you go past 2GB it will give a MAF error (memory allocation failure). I have mine enabled as my game (EQII) has a memory leak and errors out after a few hours without the /3GB switch. Now it doesn't error out anymore. at least not yet, not even on my longer 12 hour gaming sessions.

Good luck

Ya, that is not what he was trying to do so I did not link that. But here is the info about that since you mention it incase anyone would like to see if later
