I have an Asus VL/I-486SV2GX4 motherboard, which is based around the SiS 85C471 chipset. According to the chipset documentation, this chipset supports parity checking. However, the BIOS for this board does not have a setting to enable or disable parity. When looking in Modbin for hidden settings, I also do not see the parity option.

If I am to insert parity RAM, is there a check I can do to determine if parity is working, preferably some small program? Thanks!

If you can not enable it in the BIOS, it will not magically work by inserting parity RAM. There's no parity auto-detection.

I know the German "ct' memory test" (CTRAM51) is able to show if parity is enabled or not, but most hardware test/detection tools should be able to show this as well.

Know of anything in English?

If there does not exist an auto enable/disable for parity, know of any software which will enable parity?

Not sure if it supports 471 chipset tho.

I'll take a look, but I'm pretty sure it doesn't support the 471.

You sure about that? That might be, but seems like you could detect the presence of memory at the stick's parity pins. I guess if such a check was there, it would have to be a chipset feature.

If they never use the parity chip, I guess I can uprate a couple of my sticks that were built with parity of a slower grade. 😀
