- Primary Video Controller : tùy chọn thiết bị ở khe cắm hay khu vực nào sẽ được ưu tiên làm thiết bị xuất hình ảnh chính của hệ thống, điều này rất quan trọng khi thiết lập cấu hình Hybrid Crossfire. - Nếu : + IGFX : ám chỉ VGA tích hợp có sẵn trên mainboard (ATI HD3200) + GFXO : VGa được cắm ở khe PCI express, dùng khi bạn chọn ưu tiên cho VGA rời. + GPP : ám chỉ VGA rời được cắm ở khe PCI express 4x. + PCI : VGA được cắm ở khe PCI thường. Muốn kích hoạt được chế độ Hybrid Crossfire khi sử dụng VGA rời như HD2400 hoặc HD3400 series, bạn cần chỉnh về chế độ IGFX first !

With AMD Phenom, there are a total of five different types of clocks: CPU-Z *********************************************************** * Reference clock (Bus Speed) * Processor clock (Core speed) * Northbridge clock (short NB-clock) (NB Frequency) * Hyper Transport link (in short: HT link) (HT link) * Memory clock (DRam Frequency) *********************************************************** note: Phenom is much like Athlon is that is uses the same 200MHZ HTT bus frequency, it also has an overall HT frequency although this can run a lot faster than the "official max of 1000MHZ" on Athlon. Phenom uses the same base HTT bus clock of 200MHZ BUT its base HT speed is 2000MHZ for the B3CPU's such as 9850 or 1800MHZ for the lower spec B2 Phenoms or near 2X what we saw on Athlon. It also has multipliers available to push this HT bus to 2600MHZ. Multipliers available are 1 2 3 4 5 6 7 8 9 10 11 12 13 Most bios files show this as actual bus speeds, so you may see the following repor...

+ "SP:UMA Interleave Ratio" = Assign for sideport using capacity and UMA using capacity Example: sideport = 128MB SP:UMA Interleave Ratio set 1:1 ==> UMA use 128MB *********************************** JWooT -> DRAM Timing Configuration -> Memory Clock Mode Memory Clock model: auto: the DRAM speed will be based on SPDS; limit: the DRAM spe will not exceed the specified value; manual: the DRAM specified will be programmed regardless; DC Mode: ganged mode is 1x128bit dual channel unganged is 2x64 bit dual channel

A) CPU SPEED = CPU FREQ X CPU MULTI B) HTT SPEED = CPU FREQ X HT MULTI NOTE: Remember that the HT Bus (AMD systems only) is equivalent to the Bus Speed in Intel systems. Substitute the terms if using an AMD setup.The name 'HT Frequency ratio' should hint that this multiplier is the 'HT Multiplier'. C) RAM DDR2 SPEED = RAM DDR SPEED x 2 D) RAM DDR SPEED = (CPU SPEED / RAM DIVISOR ) x2 E) RAM DIVISOR = CPU MULTI / RAM DIVIDER RATIO F) RAM DIVIDER RATIO = RAM ACTUAL SPEED : CHIPSET HT BUS SPEED G) RAM ACTUAL SPEED = (DDR2 SPEED / 2) / 2 H) CHIPSET HT BUS SPEED = NOMINAL MOBO CHIPSET HT SPEED / NOMINAL HT MULTI AMD systems use a HT Link (also known as a LDT Bus) .

What settings did I use to reach 3.6Ghz with the E4300? * non-standard chilled water cooler with water at 4'C * Corsair TWIN2X2048 PC8888 memory * 400MHz FSB * 9x multiplier * 1000MHz memory * 1.65V core voltage * 2.4V memory voltage * 1.55V northbridge voltage * 1.5V southbridge voltage * 1.215V ich voltage * 4-4-4-12 memory timing But what is truly impressive is that the chip was stable at stock voltages at 3.2GHz (400x8) with the stock cooler! It was also stable at 3.42GHz with a Noctua at 1.575Vcore.

What is overclocking? Overclocking is pushing your CPU to run at a faster clock speed than the manufacturer has it set at. What is involved? FSB For Intel Core 2 Duo’s typically you overclock by simply raising the FSB (front side buss). This speed is set at 266Mhz for the E6xxx-X6800. The FSB is set at 200Mhz for the e4xxx series. Raising the FSB is the only way to overclock your Core 2 Duo, unless it is an engineer sample chip or an X6800+ (Both of these have unlocked multipliers.) Multiplier To overclock your Intel Core 2 Duo by using the multiplier, you simply change that number to a higher number than its stock multiplier. For example an engineer sample chip E6300 has a multiplier of 7x, but you can change it to a higher value, say 9x. If you leave the FSB at 266, then 9x266 = 2400Mhz = 2.4Ghz. PCI-E When you overclock your CPU by raising the FSB, you not only overclock the CPU, but you also overclock your PCI-E. On most motherboards you can lock your PCI-E to 100Mhz (recomme...

DDR2 memories are already supported on high-end motherboards. We compiled below a short list with the main differences between DDR2 and DDR memories. * DDR memories are officially found in 266 MHz, 333 MHz and 400 MHz versions, while DDR2 memories are found in 400 MHz, 533 MHz, 667 MHz and 800 MHz versions. Both types transfer two data per clock cycle. Because of that the listed clocks are nominal clocks, not real ones. To get the real clock divide the nominal clock by two. For example, DDR2-667 memory works in fact at 333 MHz. * DDR2 memories have a lower power consumption compared to DDR memories. * DDR memories are fed with 2.5 V while DDR2 memories are fed with 1.8 V. * On DDR memories the resistive termination necessary for making the memory work is located on the motherboard, while on DDR2 memories this circuit is located inside the memory chip. This is one of the reasons why it is not possible to install DDR2 memories on DDR sockets and vice-versa. * DDR modu...

Dual Channel Memory can help improve the RAM speed, because this technique doubles it. In order to use Dual Channel Memory, your motherboard has to be capable of supporting this technique and you will also need two equal memory modules. We'll explain this further, but first let's understand deeper the bottleneck problem. Understanding RAM Timings DDR and DDR2 memories follow the DDRxxx/PCyyyy classification. The first number, xxx, indicates the maximum clock speed that the memory chips support. For instance, DDR400 memories work at 400 MHz at the most, and DDR2-667 can work up to 667 MHz. It is important to notice that this is not the real clock speed of the memory: the real clock of the DDR and DDR2 memories is half the labeled clock speed. This way, in fact, DDR400 memories work at 200 MHz and DDR2-667 memories work at 333 MHz. The second number indicates the maximum transfer rate that the memory reaches, in MB/s. DDR400 memories transfer data at 3,200 MB/s at the most, hence...

Nhớ cái ni: Tốc độ của CPU được tính bằng công thức : Tốc độ CPU = Hệ Số Nhân(ratio) x bus hệ thống(FSB) VD: P3-500Mhz có HSN là 5, FSB là 100Mhz Như vậy để cho một CPU chạy nhanh hơn thiết kế ban đầu bạn chỉ “đơn giản” tăng HSN hoặc tăng FSB hoặc có thế tăng cả 2 nếu được. VD: P3-500Mhz chạy ở FSB 130Mhz bạn sẽ có con CPU P3-650Mhz mà ko tốn thêm một đồng xu nào hết ! chú ý: việc overclock sẽ làm hệ thống bị nóng lên nên phải ưu tiên giải nhiệt cho hệ thống là hàng đầu. thêm nữa cần phải tăng từ từ và kiểm tra độ ổn định của hệ thống sau đó mới tăng tiếp lên những mức cao hơn.
