Can any one tell me why, after upgrading my BOIS my RAM failed!

I've just upgraded my BIOS on my Asus A7V133 motherboard from 1003A to 1009. The flash process was completely successful. On rebooting my computer beeped continuously at me. According to the manual, this beeping, in a continuous loop, indicates 'No DRAM installed or detected'.

I replaced the RAM chip with one from my old computer. It ran okay without problems.

Can any one tell me why my old RAM works while my new RAM doesn't?

Thanks in advance.

It is possible that what you experienced was purely coincidental. the RAM failure was not due to the BIOS flash. Those things happen.

try de-grading the BIOS and see if it picks it back up again!!!!!!!

giga's right m8, i have that mainboard & the latest revision has the northbridge enhanced page mode disabled for compatibilty with samsung memory.

just try resetting ur bios to defaults first.

if that fails follow giga's advice

Thanks for the replies guys.

As far as I know all my RAM is 256Mb PC133. I don't understand why one stick of RAM should work whilst the other doesn't. Since my last post the RAM stick that failed was returned to Eclipse Computer Systems Ltd and replaced free of charge. There was nothing wrong with the RAM stick, it was replaced out of courtesy. Very nice of them I thought. Still no luck!

I've tried resetting the BIOS defaults. That had no effect.

Is there anything else I can try?

you can as far as I know with Asus Mobo's always go backwards with the BIOS, so simply falsh back to an earlier version instead of v 1009 say with v 1006
Also go here and ask/read these blokes, they are the best when it comes to BIOS and Asus boards.
