<DIV><FONT face=Arial size=2>Hello all</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am running CentOS 5 on a small server and I am
having very strange memory malfunctions.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The computer runs perfectly with no problems
whatsoever. From time to time, after a soft reboot, the computer emmits beeps
corresponding to a memory fault.</FONT></DIV>
<DIV><FONT face=Arial size=2>It never reboots again until I find and remove a
now defective DIMM. That DIMM can never be used again because it is out of
order.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This just happened for the *fourth* time and is
costing me a lot of hassle and perhaps expense if the manufacturer does not
replace the DIMM freely.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The memory is DDR400 ECC from Kingston and of the
type recommended by the motherboard's manufacturer. The board is a Tyan Tomcat
i875p (S5102).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Would it be possible that the DIMMs are being
destroyed by some software component from the OS, perhaps the I2C management?
The DIMMs do have EPROMS... Are they being incorrectly accessed by some software
component and their program modified?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Could this be the board's fault? And
how?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I don't know what to think of this, I never saw
anything like that in my already long experience with computers...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I must say again that this memory error
*never* happens while the computer is in service, it always happened upon a
soft reboot.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any hints would be appreciated.</FONT></DIV>
<DIV><FONT face=Arial size=2>Thank you</FONT></DIV></BODY></HTML>
