Without the error, the speed on this machine was the most impressive: Athlon dual 1.6GHz : 16 sec P4 Xeon dual 1.7GHz : 52 sec P III single at 700 MHz : 35 sec No error log in /var/log/message. Very rarely but certainly the Athlon dual crashed with the Reiserfs error (horrible!! I lost a file of a chapter. I recovered it only from a backup.) Initially, I thought that it is a kernel problem in the recent kernels. In the end, I realized that the kernel version really does not matter. I finally checked the memory one by one using memtest86 with the ECC disabled in the CMOS setup. No problem. I then installed all four memory modules and did memtest86. Alas!!!!, it found the memory error. Did the test three times. All three times, it always stopped in the middle with slightly different error messages, everytime reinstalled the memory modules just to be sure about the contact. That was when I returned the motherboard the second time. The first time, the board gave me a CMOS error. The third time, the board even did not give me the first beep. I now think that I should have bought the Tyan board instead of the ASUS. Regards, G.
