Best guess would be not possible.
Why not 800 x 600? If using a CRT monitor, attempting to force an unsupported aspect ratio may even damage hardware.
In my experience Xorg aspect ratios are usually 4:3 or 16:9, never 1:1. Desktop applications are designed for this.
These links might be helpful to learn more and configure Xorg:

I am using PXI-8102 controller Board which have maximum resolution of 2048x1536 at 75 Hz . I want to change it to 800x600 which is also supported but i need to change refresh rate 60 to 75 on this resolution. I mean i want to use 800x600 at 75 Hz not 60 Hz. I am using Xorg in tiny core 4.7.7
nitram:
Could set up an /etc/xorg.conf file, specify desired resolution and refresh rate. For example:
Option "metamodes" "1152x864_75 +0+0"
Example xorg.conf that you would need to customize for your hardware and needs:
--- Code: ---Section "Monitor"
Identifier "Monitor0"
#VendorName "Monitor Vendor"
#ModelName "Monitor Model"
HorizSync 28.0 - 96.0
VertRefresh 50.0 - 75.0
Option "DPMS"
EndSection
Section "Device"
### Available Driver options are:-
### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
### <string>: "String", <freq>: "<f> Hz/kHz/MHz"
### [arg]: arg optional
#Option "NoAccel" # [<bool>]
#Option "SWcursor" # [<bool>]
#Option "ColorKey" # <i>
#Option "CacheLines" # <i>
#Option "Dac6Bit" # [<bool>]
#Option "DRI" # [<bool>]
#Option "NoDDC" # [<bool>]
#Option "ShowCache" # [<bool>]
#Option "XvMCSurfaces" # <i>
#Option "PageFlip" # [<bool>]
Identifier "Card0"
Driver "intel"
VendorName "Intel Corporation"
BoardName "82810 DC-100 (CGC) Chipset Graphics Controller"
BusID "PCI:0:1:0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 16
#Option "metamodes" "1152x864_75 +0+0"
SubSection "Display"
Depth 16
#Modes "1024x768"
Modes "1152x864"
EndSubSection
EndSection
--- End code ---
There are other ways too, such as a snippet in xorg.conf.d. Maybe even xset or xrandr, no idea. You will likely have good success just researching Xorg setup, just ensure any configuration file(s) you set up are saved in .filetool.lst and backed up for persistence.

i am using persistent home. so how i change this file at startup
nitram:
Sorry slight correction, xorg.conf resides in /etc/X11/xorg.conf. You need to manually create this X11 directory if not present then place your desired xorg.conf file. Having persistent /home is not helpful as the file save is specified in /opt/.filetool.lst and after back up is stored in /tce/mydata.tgz. Add xorg.conf to backup via Control Panel -> Backup -> Included for Backup or manually add this line to /opt/.filetool.lst:
etc/X11/xorg.conf
Either run exittc and backup or in terminal run backup command to backup your settings, then reboot. With a proper xorg.conf file you will get the desired resolution and refresh rate. If not you may not be able to boot into graphics so best to learn how to use vi in terminal or install Nano. So then from text mode manually edit the xorg.conf file to try other configuration settings, then run backup and sudo reboot to try again. As mentioned, the xorg.conf file above is just an example, it can take some tinkering to get running properly. Also note it has commented out lines (#) that i am not using. You need to modify for your needs. It also specifies intel graphic driver, not sure what you need.
