as far as i know you are stuck with what you got until MS fixes PAE. Your option is a 64 bit operating system...
7820X | Asrock X299 Taichi XE | Gigabyte 1080 Ti Xtreme | 32GB Memoriez | Corsair HXi1000 | 500GB 960 Evo
Windows XP 32bit will not see all 4gb's of RAM no matter what you do. You'll have to run XP64bit or Vista.
i5 2500K @ 4.7ghz 1.32v(+.010 offset LLC set to 4) / ASRock P67 Extreme4 (B3) / 2x4gb Samsung Green MV-3V4G3D @ 1866mhz 1.35v / AMD HD 6850 1gb /2x150gb Velociraptor Raid 0 + 500gb WD Green / Corsair TX 750watt V2
I think the maximum you will get is around 3.75 GB, even with PAE activated...
The only solution is 64 bit XP or Vista 64 bit if you want to utilise all of your RAM. Or you can live without couple of hundred of MB's not being used on the XP
Although, there are 32 bit systems that can use more than 4 GB, but those are enterprise systems (Windows Server 2003 Enterprise Edition, and beyond).
What exactly did you do to activate PAE, and that doesn't work?
Intel Pentium E2160 @ 3 GHz cooled by CM Aquagate Mini R80 (80 mm Xilence Red Wing) / Gigabyte N650SLI-DS4 / 2 X 512 MB Kingmax / Leadtek PX8500GT TDH/ WD 400BB & Hitachi T7K250 / Enermax SFMA 370W Noise Taker / Chieftec Mesh series case / 3.5" Floppy drive FTW!
I have edited the boot.ini: these are the tests I have done:
1.-
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /NOEXECUTE=optin /fastdetect /pae
2.-
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /fastdetect /pae
3.-

default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /pae /fastdetect
Is Xp 64 slower than XP 32?
PAE is for servers only. Don't use it, it will result in lower performance overall.

PAE was mainly created as a stopgap solution for database servers until 64bit support was mainstream. It can't ever really be "fixed". It's a hack to emulate 48 bit addressing on a flat 32 bit space.
My gaming benchmarks have shown no noticeable performance increase or decrease in 64bit. ( +/-2% vs. of course 32bit)

Ok, thank you very much, I wish I will not have prolems with drivers or other software.
