P4C800 gives 2 beeps when booting

I recently built a system based on the Asus P4C800 mobo, with a 2.8GHz P4 and 2 sticks of PC3200 DDR ram (512M each). The system appears to run fine. However, whenever I boot up, I will get two short beeps just prior to the Asus splash screen. According to the manual, 2 beeps is supposed to mean "parity error". So, um, like, what the heck does that mean? Thinking that it might be something to do with my memory, I tried booting it with just one stick, then with just the other stick, and got the same behaviour. Putting both sticks back in, I booted again and ran a test program that fills almost all the system memory with pseudo-random bit patterns and reads/re-writes the memory areas to make sure there aren't any errors. This program will run until killed and doesn't show any memory-related errors. Anyone else with this mobo getting just one beep at start-up, and/or able to explain what might be going on?

P.S. the power-up sequence shows that the memory is running at 400MHz DDR, in dual-channel mode, just as expected.

heya dmcmahon;
This may sound strange but how many USB devices do you have, would you happen to have the same amount of USB devices as you have beeps, i know someone else that is having the same strange beeps and it happens to be the number of USB devices he has, his board is also a Asus motherboard, if we can nail this down as a problem even though it doesnt affect operation maybe they will find the error and fix it, this is a bazaar error but stranger things have happened...

Re: beeps when booting on the P4c800 dlx. After I plugged my speaker in properly on one system, I do have the beeps on both boards, corresponding to the # of usb devices I have plugged in. The usb mouse does not generate a beep. I have 2 identical p4c800dlx boards in 2 separate systems, and both do the same thing. Each system has different usb devices. 1 beep at post, and # of usb devices = # of beeps. System runs great.

As it happens, I do have 2 usb devices hooked up. Strange "feature" though.

P.S. Confirmed: with just one device attached, I get just one beep. Way weird.
