If I buy a ECC memory machine, will ECC-added-value be used "out of the box", without configuration on OpenSUSE (no SLES) ? -- : ` _..-=-=-=-.._.--.

Yes. Single bit errors are corrected, and 2-bit errors detected. I'm not sure how they are reported to the OS though. -- Per Jessen, Zürich (7.2°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

ECC is a hardware function that has nothing to do with software. In fact, it should be transparent to the operating system and apps. ECC relies on parity bits to perform error detection and correction. This is entirely done in hardware. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hi Dsant, To the best of my knowledge, ECC is handled by the hardware, and is transparent to the operating system. I recall that there are configuration options in the BIOS setups. At least I've never done anything special on ECC systems. You can also see if you have ECC by running this: dmidecode --type 16 This program should be in the standard openSuSE distribution. There's more here: http://www.pugetsystems.com/labs/articles/How-to-Check-ECC-RAM-Functionality... BTW, Puget Systems is a very good "boutique" computer vendor. I've purchased desktops from them and their service and support is excellent. I remember that they even emailed a jpg of one of the boxes they were building for me so I could keep informed and maintain my high level of excitement. The most recent systems I bought are really sweet! The CPU is fluid cooled with plumbing going to a back-mounted large low-rpm fan on a heat exchanger. Very quiet!

Yes, however how much value depends on the motherboard..some say that ECC is supported but by that they only mean it will run. not that it can make anything useful with ECC RAM. -- Cristian "I don't know the key to success, but the key to failure is trying to please everybody." -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It depends on the machine, but mine gets polled via E(rror)D(etection)A(nd)C(orrection).. during boot: [ 4.618631] EDAC MC1: Giving out device to module i7core_edac.c controller i7 core #1: DEV 0000:fe:03.0 (POLLED) [ 4.618700] EDAC PCI0: Giving out device to module i7core_edac controller EDAC PCI controller: DEV 0000:fe:03.0 (POLLED) [ 4.619295] EDAC MC0: Giving out device to module i7core_edac.c controller i7 core #0: DEV 0000:ff:03.0 (POLLED) [ 4.619337] EDAC PCI1: Giving out device to module i7core_edac controller EDAC PCI controller: DEV 0000:ff:03.0 (POLLED) [ 4.619698] EDAC i7core: Driver loaded, 2 memory controller(s) found.
