CLI memory teste needed

[SvenBent]

I'm asking the many wise programmers on encode.su for a utility i need for my stress tools package.

i would need a simple memory test that runs from within window like HCI memory test.

i know its better to use memtest86+ or the tools from MS withc is bootable. but it is for it is for another scenario.

The utility needs the following
- auto-detect available memory and test it
- just a simple walk with checkerboard and inverse checkerboards is fine
- needs to be able to above 4 gb memory
- needs to be able to run under win7 x64
- sble to start from a batch file

nothing more is really required but i have no usable programming skills. as all my programing skills are from before windows 95, and even back then i didn't know how to work segments so i could only address 64kbytes of memory.

its is to be used with dnetc +furmark for stress testing pc in a little PC distributor.

PPL will get credits in the readme/help of the package


nice features to have
- able to run under both windows 32 and 64
- parameter for a mod value for the checkerboard mask e.g i write "-mod 128" and it would mod the checker board mask with 10000000 bit mask

The x64 requirement is a bit hard imho - its a bit annoying to access
_all_ memory from a 32-bit app, and a 64-bit app won't run on 32-bit systems.
Otherwise it could be a simple program which allocates all the available
memory and rewrites it - but a specific version for each platform.
It won't do much good as a memory test though, imho.
So what about using some compressor with 64-bit version instead?
Afair freearc had some memory size detection?..
You can try compressing and decompressing something big enough with it,
using all the available memory, and if it crashes or verification fails - that's it.
Would be a better test imho.

Thanx for the reply

i didn't knew fa had the autodetect memory usage and i think it would be acceptable for my purpose. i will look into it


32bit windows support is really not need but support for above 4gb system is.


and i agree the a simple run of checkerboard/inverse checkerboards is not much for a ram test, but its better than nothing. And i wouldn't ask ppl for a big project to make for me free.

Googling shows much of the internet thinks limiting processes in win32 is impossible, but then perhaps they don't know about Job Objects with a JOBOBJECT_EXTENDED_LIMIT_INFORMATION specifying memory limits?

I was aware of these but they dont use CLI to start them which i need for my batch script. hci is cli usable in pay version, but the licesn restricts the usage i need it for. hence why i need a freeware utility

[Shelwien]

there're sources for rightmark thing though...
there're really no command line options it seems, but
you can fix it to autostart and recompile

but then we are back at this issues. with my lack of skills in this area
