上次組裝電腦已經是6~7年前的事了,昨天終於下定決心把公司那台半古董桌機換下來,一方面增加工作效率也讓已經逐漸老化的硬碟退休.
之前已經在網路上研究了配備一陣子,主要還是與Ubuntu的相容性要好.最後定案的配備如下
Intel I5-2500K (有K的表示可超頻,貴幾百吧)
ASRock Z68 PRO3 GEN3 (這張Ubuntu直上,還有一個COM port,重點是便宜啊)
Kongston 4GB DDR3-1333 x 2 (共8G memory,這在十年前簡直是無法想像)
Seagate SATA3 1T ST1000DM003
CM Hyper 212 PLUS 塔型散熱器 (CPU不怕著涼的,裝大顆一點就對了)
振華400W power
裝好搬回來後直接裝Ubuntu 11.10,一路順暢都沒有什麼問題.
我最擔心的Intel HD 3000 graphic controller也能正常工作,Perfect
接著是一些監控系統資訊的方式
1.CPU 溫度
modprobe coretemp
sensors
gigijoe@gigijoe-i5-2500k:~$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +31.0°C (high = +80.0°C, crit = +98.0°C)
Core 0: +25.0°C (high = +80.0°C, crit = +98.0°C)
Core 1: +29.0°C (high = +80.0°C, crit = +98.0°C)
Core 2: +26.0°C (high = +80.0°C, crit = +98.0°C)
Core 3: +30.0°C (high = +80.0°C, crit = +98.0°C)
2.硬體資訊
sudo lshw
3.CPU 超頻
現在的超頻很容易,直接在BIOS內用懶人設定選取希望的頻率即可.
3.3G -> 4.6G還蠻穩定的,CPU溫度只稍微上升.
在linux環境下cat /pro/cpuinfo會發現超頻之後的CPU clock一樣顯示是3.3G.
嗯,經過一番google後先試著用wine 跑 CPU-z這個Windows上廣泛使用的程式...失敗.
最後正解是一隻叫i7z的程式 http://code.google.com/p/i7z/
Cpu speed from cpuinfo 3292.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 3292 MHz
CPU Multiplier 33x || Bus clock frequency (BCLK) 99.76 MHz
Socket [0] - [physical cores=4, logical cores=4, max online cores ever=4]
TURBO ENABLED on 4 Cores, Hyper Threading OFF
True Frequency 3391.76 MHz (99.76 x [34])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 60x/60x/60x/60x
Current Frequency 1793.89 MHz [99.76 x 17.98] (Max of below)
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 %
Core 1 [0]: 1793.89 (17.98x) 38.2 38.7 9.4 31.1
Core 2 [1]: 1655.03 (16.59x) 9.69 13.6 5.07 76.5
Core 3 [2]: 1657.92 (16.62x) 2.77 2.38 1.3 94.9
Core 4 [3]: 1618.08 (16.22x) 1 0.747 0 98.9
C0 = Processor running without halting
C1 = Processor running with halts (States >C0 are power saver)
C3 = Cores running with PLL turned off and core cache turned off
C6 = Everything in C3 + core state saved to last level cache
Above values in table are in percentage over the last 1 sec
3.還有一個小問題是boot會卡在Checking Battery State.
按Ctrl+Alt+F1進 console login.
sudo apt-get install gdm
安裝過程中選lightdm
或是
sudo dpkg-reconfigure gdm
然後reboot就解決囉
