Thinkpads Forum

Ah, thanks, I hoped that somewho else tries it OK, it seems to be indeed a memtest86+ problem then - see also the strange frequency and CL-values. They seem to be random, and after a short Windows boot there are zero.

On one of the laptops I got one bit flip with 4x memtester 1536M, but during a nigh-tlong test no further problems.

P.S. it seems that http://thinkpad-forum.de is dead?
