我租了一台服务器,服务器上有:8 GB DDR3-RAM ECC。
在启动时,日志文件打印如下所示:
EDAC amd64: This node reports that Memory ECC is currently disabled, set F3x44[22] (0000:00:18.3).
Jan 15 03:24:44 big kernel: [ 75.821734] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.

我在SupermicroX10SLM-F/XeonE3-1271 v3上运行ubuntu服务器14.04
内存: SuperTalent 32 ECC DDR3 1600 ECC
大约每4天,Ubuntu上的日志将显示如下:
{1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 1
{1}[Hardware Error]: It has been corrected by h/w and requires no further action
{1}[Hardware Error]: event
我有一个富士通TX150 S7,我想为它升级内存。我原以为这很简单,但显然并非如此。
该服务器的手册声明如下:
Memory slots: 6
Memory slot type: DIMM (DDR3)
Memory capacity (min. - max.): 1 GB - 32 GB
Memory protection: ECC
连同一些注释:
Memory notes: For the following modules a maximum of 4 DIMMs can be configured:
4GB (quad-ranked) with 1066MHz, 8GB RDIMM,
我试图找出RSA和ECC在TLS 1.2密码套件中的用途。
让我们以TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256为例,服务器和客户端之间的通信将如下所示(根据下面的答案进行修改)-
C S
|<<------| 1. [PlainText] signed certificate
|------>>| 1.1. [RSA] Authentication: encrypted message using the public key in certificate

我有一个运行Ubuntu12.04服务器的无头工作站,最近安装了新的Tesla C2070卡,但在运行CUDA SDK中的示例时,我得到了以下错误:

如何禁用有关ECC的这些警告?我没有ECC内存,所以在bios中也禁用了它,但是它仍然打印它。
[ 4.697057] EDAC amd64: Node 0: DRAM ECC disabled.
[ 4.697061] EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
Either enable ECC checking or force module loading by setting 'ecc_enable_override
