To: linux-kernel@vger.kernel.org Date: Mon, 3 Sep 2001 01:13:51 -0700 (PDT) X-Mailer: ELM [version 2.5 PL2] MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Message-Id: From: Eric Olson Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I have found these Athlon problems are very interesting. Is there a usermode memory testing program which uses the K7 MMX 3DNow streaming cache bypass load/store instruction sequences that appear in linux/arch/i386/lib/mmx.c ? Could Robert Redelmeier's burnMMX at http://users.ev1.net/~redelm/ be modified for the Athlon to detect these problems? It would be usefull to have a Microsoft Windows program that could detect a faulty system without having to load Linux. This would allow testing a system in a store before purchase, and quick testing of a new system shipped with Windows to determine whether it needs to be returned before reformatting the harddisk and installing Linux. The reports I've know are for KT133 motherboards. Have problems been reported with the KT266 DDR-SDRAM chipsets as well? All the best, Eric Olson
