I have been using the setup described below for a very long time, the only significant recent addition (apart from a nice new Lenovo 2440x 24" widescreen monitor with LCD backlight) is the addition of 2GB to the previous somewhat sparse 1GB of RAM, but sad to say that's the reason behind this new thread...
So, with my original 1GB of DDR-DRAM, the PC booted up and always emitted one single beep during the process.
But now that I've added two more 1GB banks of DDR-SDRAM, the BIOS sometimes emits a second beep 7 or 8 seconds after the first. When this occurs, the boot process then continues as normal and the PC functions as before other than reporting the RAM now as 3GB.
Thinking there might be some mismatch between the old & new RAM banks, I tried fitting just the two new banks and heard always only one beep. Fitting the old bank together with the new, no matter in what order (old-new-new or new-new-old) the BIOS sometimes emits a second beep.
The old 1GB bank is labelled so:
takeMs 1GB DDR 400 CL3 PC3200
The two new 1GB banks are labelled similarly:
Kingston ValueRAM 1GB DDR 400 CL3 PC3200
Both old & new banks carry memory chips on both sides of the PCB
My SiSoftware Sandra reports the RAM as follows:
Total Memory: 3GB DDR-SDRAM

Bank2/3 - A1: DIMM 1GB/64 @ 400Mt/s

I have checked my BIOS settings and see nothing untoward. Speed is shown as 200MHz; I can change this upwards but not downwards.
Anyone any ideas, please?
