I did run it once, for a little more than half an hour. All seemed ok, but I think that only the "visible" 128Mb part of the 256Mb sticks were tested, the "missing" 128Mb left being ignored.
that problem is IMHO a BIOS problem. I have seen similar. My guess is the chips on the SDRAM are too big, and the BIOS doesn't support the highest address line. I had one that only saw 128M of a 256M stick, because IIRC they used 64M chips, and the largest I could use was 32M chips. I could use 256M SDRAM, but I could only use the lower chip size. I was able to swap for an older 256M that used 32M chips with a newer machine. YMMV, but the newer the memory, the possibility of them using the bigger capacity chips (lower chip number) on the stick goes up, and barring the motherboard coming out with a BIOS update to fix it (assuming it isn't a hardware limitation), you may have the same problem with newer memory.
That's possible.
The strange thing is that when I first installed the memory sticks, they properly showed as a total of 768Mb RAM. Later, I realized that the RAM had fall to 384Mb.
I also recently updated the BIOS, but that didn't fixed the problem.
Erm, well, while I was installing the new 256Mb SDRAM I bought, I saw the older RAM sticks were NOT 256Mb as I thought, but 128 ! (Shame on me) I don't know were I saw I was once having 768Mb, as it was not possible. Maybe I dream too much... (At least, that made me upgrade the BIOS and increase the available RAM) Hu-ho, Memtest-86 is now reporting errors at Test 7 - Random number sequence: various locations, but the Err-Bits is always 00000080 AmigaPhil, world citizen. /No MS-HTML mail please/ PGP key: 0x9C07F6C1 -----BEGIN NSA TEASER----- The following garbage may or may not contain crypted message.
