查了一下BIOSTAR
有PCB Version : Ver. 7.x Ver. 7.1 Ver. 7.0
但cpu支援 PENTIUM 4 505 2.66GHz處理器卻是沒有
網路搜尋 的確有此處理器
Intel, Pentium 4 505J, 2.66GHz, 1MB, Prescott, 90nm, E0, 84W, 533外頻
看cpu支援度
其實可以看板子支援度
從這裡看來就是最高支援95w 266外頻
超頻從功耗角度
84w至95w 但95w是基本 所以為了穩定還會再往上支援推測是105w
3相好像是125w
4相好像是140w
雖然早就知道via的晶片不好超 而且是合版內顯
仍下載手冊下來看
看了半天
本來不想看 你讓我認真了:lkl:
BIOS這裡
Performance Booster Zone
DRAM Clock
This item determines DRAM clock.
The Choices: By SPD (default), 100MHz, 133MHz, 166MHz, 200MHz, 266MHz, 333MHz .
你設最低100MHz (超外頻 就不能設spd)
CPU CLOCK外頻
This item allows you to select CPU Clock, and CPU over clocking.
Special Notice:
If the system’s frequency that you are selected is not functioning, there are two methods of booting-up the system.
Method 1:
Clear the COMS data by setting the JCOMS1 ((2-3) closed)) as “ON” status. All the CMOS data will be loaded as defaults setting. 這裡寫到清CMOS
Method 2:
Press the <Insert> key and Power button simultaneously, after that keep-on pressing the <Insert> key until the power-on screen showed.
This action will boot-up the system according to FSB of the processor
It’s strongly recommended to set CPU Vcore and clock in default setting. If the CPU Vcore and clock are not in default setting, it may cause CPU or M/B damage.
這裡寫到超外頻的壞處
The Choices: 100MHz(default); Min=100, Max=400, key in a DEC number.
外頻可設100~400
你的CPU應該是抓133 調整134 慢慢加+1
Async PCIE CLOCK定頻
This item allows you to select Async PCIE clock.
Min= 100 Max=150 Key in a DEC number.
The Choices: 100MHz(default)設定不要動 ; Min=100, Max=150, key in a DEC number.
定頻PCI-E=100MHZ
CPU Clock Ratio倍頻
This item allows you to select the CPU Ratio.
Min= 6 Max= 50 Key in a DEC number.可以6~50
The Choices: 6X (default).原則上我猜應該是抓20x 且官方鎖倍頻
你的cpu原先設定
133*20=2.66G
你超134 慢慢加1 開看看 一直開到140
能上140
140*20=2.8G 再用SP2004下去測穩定度
至於記憶體設100MHZ 是最低除頻 為了上高外頻(參數自己摸索)
原則上 消耗功率超頻就是84W~105W
如果BIOS 裡面都沒有 就是沒法超頻
因為你的CPU不是工程版 沒鎖倍頻的
買不到BIOSTAR的版子啊~因為維修不易啊~
