Hi, |
2 |
|
3 |
maybe write your hw configuration first. Eg: CPUs, graphic cards, HDDs |
4 |
(size, speed, type) and others. |
5 |
|
6 |
Also provide lspci output and /proc/cpuinfo. |
7 |
|
8 |
Then this is a server, maybe with more than one GB nic. If you dont use |
9 |
spare nics disable them in bios. Do the same with other unneeded stuff. |
10 |
|
11 |
If you can access your server and replace cards, remove everything you |
12 |
dont need. Do not lower fans or dont play with cpu voltage. If you want |
13 |
to run this server 24/7 it can cause serious problems. It will not save |
14 |
you much power. Paradoxly this could lead to higher power usage in |
15 |
some cases, because of hotter devices. |
16 |
|
17 |
Remove spare memory cards, if you dont need much memory, etc. |
