新手超 i7-930 問題 ???

choi_b

以下係我個簡單超頻setup:
bclk = 180, multiplier = 20, cpu speed = 3600 mhz, ram 行 2:8 = 1440, uncore = 2x ram = 2880, QPI = bclk * 36 = 6480, vcore = 1.25, ram voltage = 1.65, QPI voltage = 1.2

1.) 以上setup 可以穩行, 我想問如果我將 bclk set 做 200, multiplier set 做番 18, 得出黎o既cpu speed 都係3600mhz 無變, 咁理論上我係咪唔使加電壓都可以穩行呢? 我知道set高左bclk o既話, uncore 同埋QPI 都會相對地提高, 但我唔知對超頻成功率會唔會有影響. 如果我要加電壓黎行高 bclk o既話, 咁我應該加vcore 好定係加 QPI voltage好???

2.) 我真係好迷失, 底板仲有好多我從未見過o既 voltage 比我set, 例如: CPU PLL voltage, IOH voltage, ICH voltage ...... 我唔敢搞呢d voltage :funk: 我想問隨左 cpu vcore, ram voltage 同埋 QPI voltage 之外, 仲有冇邊d voltage 我要留意架???

咩板? 行bclk 180 i7 920 都做到而且, vcore 唔使1.25v. 930 at least 行200x20 la

asus p6x58 premium, 我唔識超呀, defaul cpu voltage 行 1.2, 我諗住比多少少佢先, 一開波就 set 1.25, 可能 1.2 都已經穩行 180 * 20, 但係我冇試過.
ching 有冇咩野建議呀? d 電壓點 set, 我而家頭都大埋...... 仲有我而家 cpu full load prime 95 = 71 度, 正唔正常? heatsink 係用 venomous x,  2 * wing 12 push pull full fan speed

1. 200bclk x18, CPU freq雖然一樣,但RAM就變成1600, uncore就變成3200, QPI就變成7200.整體速度係會快少少.

Vcore應該冇大分別,3200 uncore我諗QPI行返1.2V都可以,頂盡1.3V但RAM timing可能要改一改.如果你d RAM唔係1600,咁就要花少少時間去set o下d RAM先~

2. PLL = Phase Lock Loop, IOH = NB = mainly PCIe control. ICH = SB = SATA, USB....etc.自己Google唔講啦. 可以講你知200bclk冇需要去改呢d 電壓,行default就得.頂盡IOH由1.1V set去1.2V(我自己冇改).

我條ram 可以行 1600 c9 timing, 如果我冇理解錯, 照你所講我係咪可以直上 200 * 20? 如果唔穩, 我淨係加 cpu vcore 就可以啦? 因為而家超i-7 有好多野要理, 唔同以前淨係得 fsb, multiplier, vcore 三樣

我自己會先行memtest (CPU multi set x12),set好RAM timming同試o左uncore/QPI要幾多電先.

當uncore冇問題先至再去超U.但我見你3.6G都要70C,4G可能會過80C喎........Wing12未必頂得住,考慮o下Wing12 PL/Excalibur~~~

不如拉盡個倍頻呀

wing 12 PL 乜唔係同 wing 12 一樣 spec 咩?
我機箱係用 silverstone ft02b, heatsink 已經用 venomous x, 室溫只係 26 度, 呢個cpu溫度係咪有d唔正常呢? 會唔會係我 heatsink 安得唔好所致? venomous x 扣好似唔係好穩陣咁, 上實左仲可以左右擰 :funk:

Wing12 PL up to 1800rpm (Wing 12 = 1500rpm), and has higher pressure, which is good for HS, but a bit more noisy too.

VX 上實左仲可以左右擰 is normal.

vcore 1.24, QPI 1.2V, DRAM 1.66V, 3.8Ghz, 燒 PRIME 95中, 溫度仍然 keep 到70度, 好似幾穩咁
上網睇過其他 FORUM, 話QPI 同埋 DRAM voltage 唔好超過 0.5V 差別
