wat pe nak running 1:1 ?
bukan jimat banyak sangat karen pon...? |

to my knowledge, it's for performance. you avoid bottleneck for data transfer when your cpu and ram ratio is 1:1.

memanglah ada bottleneck...
tapi untuk avoid bottleneck, perlukah kita upgrade atau downgrade sesuatu komponen pula? Foe eg... dah ade RAM power, proc tak power, tak leh naikkan frekuensi proc terpaksalah kita downgrade RAM eh?

you don't have to do that if you don't want to. that's why it's important to know the first time you build the PC. regular user may not feel it because the process is so fast. gamers, they usually do and do pay attention to 1:1 ratio.
by the way, you can have the best PC in the house but if you don't maximize its performance properly, you'll probably say, my old PC is faster than my new one - happens all the time (people like to complain rather than understand).

aku rasa kalau ko tengok pada kotak m/board pun dia dah sediakan
spec2 yg sesuai untuk ko jalankan projek ko tu....dan dari spec yg ko bgtau cpu ko
1.8ghz kalau ko check rasanya dia punya FSB800. cukup kalau ko pakai
1.6ghz atau 1.5ghz pun da memadai. dua2 tu mempunyai 667mhz so aku rasa
(walau aku tak pasti) match la ngan DDR667 ram ko tuh....pape pun tanyala pada yang pakar. |

Timing dan tuning RAM untuk processor Intel amat bergantung kepada jenis chipset yg ko gunakan,
Dan ianya meliputi keseluruhan penggunaan chipset dan RAM.
Technically, Chipset Intel 865 dan 875 adalah dua chipset yg mempunyai ciri2 yg hampir sama cuma chipset
Intel yg memiliki satu function yg takde kat 865.iaitu menyokong RAM ECC (Error Checking And Correction)
Maknanya, Dua Chipset ni hampir memiliki funtion yg sama.
Bila masuk bab Tuning Ram ngan Processor ni, maka ia akan menerangkan keboleh-upayaan Chipset
berkenaan dalam menyokong Bandwith RAM.Arkitektur Chipset hanya membenarkan Bandwith RAM
berfungsi BERDASARKAN keboleh-upayaan FSB yg disupport Processor terbabit.
contoh
1.FSB 800 menyokong DDR400, DDR333, DDR266
2.FSB 533 menyokong DDR333 dan DDR266
3.FSB 400 menyokong DDR266
Ada banyak cara nak tingkatkan keboleh-upayaan prestasi ram..dengan cara TIMING RAM dgn mengubah
atau resetting CAS Latency,tRDC( Ras To Cas Delay) dan sbgnya....kalau tak set pun xpe
cuma macam bawak keter tayar kempis, minyak byk guna, perjalanan x lancar...
papepun rujuklah pada yang pakar kat sini... |

Sekarang nie aku guna P4 2.53 Ghz FSB 533,
adakah untuk mendapat ratio 1:1 aku perlu tanggal ram PC3200 aku nie dan tukar ke PC 2100?
haiyah... |

alahai ko nih....benda dah ade, ok dan ko pun dah bahagia ngan spec yang ko ade
skang nak wat per lagi pikir tu sume...bagi kat mereka yg concern bout this matter jer pikir....
hehehehehhe.......... |

i was confused too. i believe the forumer wanted to ask clock speed rather than core speed.

Bagi kes aku pulak, aku nak overclock so aku main dengan setting divider.
First, spec:
AMD Athlon 64 3000+ Venice E6
Asus A8N-E
Kingston VR DDR400 512MB x2 (Hynix BT-D43)
Stock konfigurasi:
HTT (FSB) = 200
CPU multiplier = 9
CPU clock = 1800
RAM clock = 200
RAM timing = 3-3-3-8 2T
nisbah RAM/HTT = 200:200 = 1:1
Selepas oc (terbaik buat masa kini):
HTT (FSB) = 266
CPU clock = 2394 ~2400 lah hehe, clockspeed 3800+ 
RAM clock = 218 ~222 utk senang
RAM timing = 3-4-4-9 2T
nisbah RAM/HTT = 222:266 = 5:6
Extra: untuk kira RAM clock dari CPU clock
CPU clock/(CPU multplier/divider ratio)
2400/[9/(5/6)] = 222 ...agak tepat
Nota:
1. Stock AMD heatsink, satu 120mm fan biasa dalam casing je.
2. Voltage semua aku tak sentuh memandangkan cooling tak cukup.
3. RAM D43 buleh cecah 266 untuk ratio 1:1 dengan HTT, tapi kena up voltage. Kingston xde heat spreader. RAM limit.
Kesimpulannya: Selepas overclock, walaupun 5:6 tapi lagi power dari stok yg dividernya 1:1. Maka, divider takdelah sepenting mana dan berguna kalau nak overclock CPU kaw kaw dengan RAM biasa. |
