Hi John, I've been testing RAM for 2 hours in user space with 3 parallel processes of sysutils/memtest. What can I say? I just got this in second loop of memtest: Loop 2: Stuck Address : ok Random Value : ok Compare XOR : ok Compare SUB : ok Compare MUL : ok Compare DIV : ok Compare OR : ok Compare AND : ok Sequential Increment: ok Solid Bits : ok Block Sequential : ok Checkerboard : testing 59FAILURE: 0xaaaaaaaaaaaaaaaa != 0x400300007007 at offset 0x007dc608. FAILURE: 0x5555555555555555 != 0xf0000070ef00007 at offset 0x007dc609. FAILURE: 0xaaaaaaaaaaaaaaaa != 0x00004003 at offset 0x007dc60a. FAILURE: 0x5555555555555555 != 0x00004002 at offset 0x007dc60b. FAILURE: 0xaaaaaaaaaaaaaaaa != 0xffffffff807cb4e0 at offset 0x007dc60c. FAILURE: 0x5555555555555555 != 0x00000000 at offset 0x007dc60d. FAILURE: 0xaaaaaaaaaaaaaaaa != 0x000002fa at offset 0x007dc60e. FAILURE: 0x5555555555555555 != 0x00000000 at offset 0x007dc60f. Bit Spread : ok Bit Flip : setting 35^C I think this is obvious enough. Thank you for your patience with me. This was a good hint. I would have never thought of a RAM defect. -- Martin
