Delivery! Sempron overclocking motherboard purchase book
Source: PConline Author: Dong Yun, floating [2004-12-01 00:34:10]
On July 29, 2004, AMD officially issued a Sempron series processor. The Sempron processor is AMD to replace the DURON processor, the name originated from the Latin Semper (meaning "forever"), plus the technical suffix RON (meaning "low-end processor"). The Chinese name of this series of processors is "flash dragon", including "like lightning, such as stars shine", which has also fully embodied Sempron's main attack direction is a low-end market (low-end SEMPRON2200 market) Only 355).
Flios Dragon Series CPU's outer box This is a sempron2200
However, since AMD replaces a new PR value naming method again on the Sempron processor, the same nominal Athlon XP and the SemPron processor frequency does not correspond, so the same identified SemPron and Athlon XP, performance Can't wait. However, the Sempron series of CPUs still have a good inheritance of the overclocking characteristics of the CPU of AMD. Detailed overclocking evaluation See "Review: Sempron Fraction Yang D Low End Wang Hui Want"
I. Precautions for overclocking SEMPRON
Let's take a detailed understanding of some details of Sempron overclocking.
1. The real frequency is equipped with a real frequency (such as the Great Wall 300P4, priced at 150 yuan) and the motherboard that can stabilize the CPU. The stability of power supply directly determines the stability of the machine after the overclocking, only the voltage current is stable, in order to make the CPU fully exert its overclocking potential.
2, the heat sink purchase as much as possible to purchase well-known brands such as TT and AVC, Coolermaster, their products are quite strict from design to work, and ensure that the CPU does not overheat to stabilize the overclocking machine.
3, equipped with memory. Because if the memory does not have a high frequency, it will become a bottleneck that will become overclocking in the whole machine, limiting the CPU to higher frequencies. The author recommends that overclocking users choose KST, Kingmax's memory, and the quality is more guaranteed. In order to overclock successfully, the outer frequency and memory running frequency of the motherboard can be selected into asynchronous operation, so that the memory subsystem of your system maintains stable data processing performance at high frequencies. But remind you: Try to keep the outgoing frequency and memory frequencies so that the strongest performance performance can be obtained.
4. Improve the heat dissipation of the North Bridge, the performance of the North Bridge is critical to your CPU to get higher foreign frequency, so DiYer can try to create a more powerful heat dissipation system for the North Bridge.
Second, the principle of sempron overclocking motherboard purchase
Sempron's overclocking motherboard is purchased from the following aspects:
1, must be over 200 or more, because the Sempron series CPU multiplier has been locked, and overclocking can only be superio. Therefore, a motherboard that is not suitable on an outer frequency is not suitable for overclocking SEMPRON.

2, the motherboard is stable to the power supply of the CPU. This is to look at the materials and work of the motherboard. In fact, the motherboards, work and prices in many first-line big plants are now intensive. Do work (such as ASUS, MSI's high-end motherboard) often price is worthwhile; and the low-cost motherboard (such as Hua Shi, Xing Xing's low-cost motherboard) is relatively humor. Therefore, when you purchase, you should carefully observe the comparison, for example, is it necessary to watch the power supply design of the motherboard (Sempron overclocking power consumption is not large, one design reasonable two-phase power supply design is sufficient to ensure the system Stable operation); whether the capacitance used by the motherboard is quality pass (the quality of the capacitance of the quality, even the phenomenon of the pulley), do not look at the brand and the price, we will decide to purchase.
3. As the main board for overclocking, there must be as many over-cell settings as possible. Such as: The voltage of the CPU can be adjusted in a smaller unit (the general motherboard on the market is adjusted in 0.025V); support 6 division, even the frequency of the AGP, PCI; the memory voltage is adjustable. It is best to have a function of automatic recovery of overclocking failed, so that in case of overclocking failure in debugging, it is not necessary to remove the CMOS without disassembling the chassis.
4, in the end, the author believes that the reason why Sempron is selected is for its outstanding cost performance. So, when choosing the Sempron overclocking motherboard, it is best to be 600 or less. If you exceed 600, you will be less cost-effective -_-
In addition, we should learn more commonly supported Sempron chipsets in several markets:

A fully equipped I / O interface including fiber optic interfaces.
In general, the motherboard is a main product, powerful, overclocking ability, is a high-end model in the NF2 motherboard. The media quotation of this motherboard has been launched 790 yuan. Falling to 590 yuan, friends who pursue functions may wish to pay attention. 3, Yan Zheng 8VTAI market reference price: 499 yuan
Advantages: Compared with the NF2 motherboard of the same price, SATA is supported, and the VIA's KT series is better in the user's compatibility word of mouth.
Disadvantages: More unfortunately, there are few memory slots, only two, but this kind of ratio is not too picky.
Yanzheng 8VTAI continues the stagnation style, using generous green PCB substrates, and the components of the entire motherboard are reasonable, and the installation of each accessory does not conflict. This motherboard supports full range of Socket A (AMD K7) processors and provides support for dual channel DDR400 specifications while supporting asynchronous transmission. The introduction of dual-channel technology has made a large increase in the performance of the memory system and overclocking space. However, it is not enough to provide 2 memory slots, which makes the main board's upgrade space decline. The performance specifications of the motherboard, everyone see the label on this packaging.
Most of the KT880 motherboards are two-phase power supplies, this is no exception, and the capacitors are three three-dimensional capacitors, five OST capacitors, and mid-rules.
ATXP1 is an overclocking / protected two-in-one Super PLL chip, typically near the CPU slot. It can ensure that the CPU, Memory and AGP or the like are divided by dividing, voltage regulation of the CPU, Memory and AGP, etc. if the CPU does not cause burnout due to the unstable voltage unstable. The overclocking options on the Qizheng motherboard and the adjustment function of the relevant parameters are it controlled.
Comparable Alc655 and VT6103 chips provide 6 channel AC97 sound and 10-100M adaptive network function.
In the backplane output interface, in addition to the common interface, there is also a S / P DIF interface.
KT880 is the only chip that supports dual-pass in VIA's KT series, as well as the KT series to be used and NF2 counterfeit weapons, its performance and NF2 series on the same grade. This price of EP-8VTAI, which is produced by traditional big factory, has been killed below 500, which is undoubtedly another better choice for Sempron overclocking. 4, Qingyun KM400A Pro market reference price: 488 yuan
Advantages: The material is solid, and this price uses KM400A's motherboards, and the 8237 South Bridge supports SATA is also a highlight.
Disadvantages: The material is not unified, some versions use ordinary brand capacitance rather than Sanyo capacitors, pay attention to check when purchasing.
Qingyun KM400a Pro uses Micro ATX small board design, based on the traditional blue PCB style of Qingyun, is quite rigorous, and it is also good. The motherboard is integrated with the VIA UnichRome graphic core of GF2 MX400, and has also left an AGP 8X slot for users who want later upgrades, as for the 6-channel AC97, 100M NIC also onboard.
This motherboard uses a combination of VIA KM400a North Bridge VT8237 South Bridge, which is the specific performance parameters.
Since the Nanqiao wafer uses VIA 8237, S-ATA is supported, which has made it a largest function of the low-cost KM400 series motherboard on the market.
The power supply section uses two-phase power supply design. Due to the capacitance of the Japanese Factory Sanyo's 2200U capacitance, the quality is trustworthy, sufficient to ensure the stable supply of CPU overclocking.
Rich interface.
In terms of attachment, the data cable with S-ATA and the hard disk line, in the low-priced integrated motherboard, is indeed.
If your entire machine budget is within 4000, the 3D performance requirements are not high. Then this Qingyun KM400A motherboard will be a good choice. 5, Shuangmin UK600N Lite Market Reference Price: 399 yuan
Advantages: Although the performance in terms of the medium rules, this price is really unacceptable, and the accessories are very complete.
Disadvantages: Usually, the capacitance near the CPU socket is too close, and some fans may be difficult to install.
With a large number of KT880 motherboards, single-channel KT600 motherboard sells to completely throw a full throw, to KT400 series, such as this double-sensitive UK600N Lite, although there is no support for dual channel, but 399 yuan low price, and such workmanship , Materials, or a lot of pursuit of cost-effective users. Motherboard and all attachments (SATA data cable, IDE data cable, soft drive line, manual, warranty card, drive disc)
This UK600N Lite adopts a VIA KT600 North Bridge, a combination of VT8237 South Bridge. Supports all Socket A (AMD K7) processors, up to 400 front-end bus, providing three DDR400 memory slots. Supports S-ATA150, providing 2 groups of SATA interfaces, 1 group 10 / 100Mbps network interface, integrated 6 channel AC'97 CodeC sound card.
Three-phase power supply, Taiwan SACON capacitor. This motherboard provides more overclocking settings: support CPU temperature, voltage monitoring function; support BIOS to adjust CPU outgoing, multiplier, and core voltage; support AGP / CPU / DIMM voltage BIOS adjustment function; support watchdog technology, Whether the automatic diagnosis system is overclocking, when the instability is detected, the system is automatically restarted within 5 seconds, and the BIOS default function (without disassembling the chassis); support VIA VLINK8X technology.
In general, the price of the motherboard is low, the extensibility is also good, and the three-phase loop is powered, it can be good to ensure that the CPU's overclocking power supply needs, it is very suitable for low-cost users with overclocking dragon. 6, Huao K7S41 market reference price: 410 yuan
Advantages: The traditional advantage of the ASRock is cheap, and this motherboard integration is very high, full of functions, is a good choice for ultra-low-cost configuration.
Disadvantages: The materials are so thin, giving people a single feel.
The ASRock K7S41 uses the SIS 741 963L chipset that applies SIS's HyperStreaming Engine, Ultra-AGPII, SiS Mutiol 1g, etc., so that its overall performance reaches a level similar to KT600. The appearance looks like this K7S41 motherboard material is relatively humored, and the number of slots is also small. However, since this motherboard has integrated sound card, NIC and graphics card and other functions, the scalability is sufficient for general users. As with KM400A, the AGP 8X interface is available, which can meet users with upgraded graphics.
The motherboard also uses two-phase power circuit to power the power supply. Each output coil is matched with 2 MOSFETs (transistors), and the filter capacitance is a product of Japan NCC (NCC has acquired US old professional capacitor vendor sprague), the same is enough Meet the overclocking needs of Sempron.
This motherboard integrates the REAL 256E 3D GFX display chip, which has a comprehensive efficiency similar to GF2 MX 400, and the maximum can share 64MB of memory from memory (but the author suggests that it is 32M, the setting 64m is almost no performance). If the user feels that the performance of the integrated graphics card is not enough, you can also use the AGP8X slot on the motherboard to switch to an external discrete graphics.
As for overclocking options, this K7S41 provides Hybrid Booster safe overclocking technology: support CPU Frequency Stepless Control (CPU Stepless Frequency Regulation), CPU Multiplier, CPU Vcore Adjustment ASROCK U-COP (ASRock General CPU overheat Protection Technology) and Boot Failure Guard (boot failure recovery technology). We can see a lot of useful overclocking options in the BIOS, which shows the use of the ASRock in the design of the motherboard. It is convenient for DiYer's use. Insufficient in the United States is no adjustment of various voltages. In actual use of this ASRock's K7S41 motherboard is not ideal in game performance, but considering that its price is only 400 yuan, this motherboard is still a good choice. The price of 410 yuan is also difficult to find a comparison in the integrated motherboard of other brands, and can achieve such an attainment in the layout of the PCB. Therefore, the author recommends that DiYer chooses this motherboard when a person (such as MM) distribution of 3D games.
Fourth, summary
For a Sempron processor that is not a large power consumption, the above-mentioned motherboards can easily overclock over 200 or more. Of course, there are some excellent motherboard products on the market, such as the NF7, Onda NK7U ... Limited to the space, this will not be introduced here. You can choose according to your actual needs and overall budget. The author believes that in the Socket 462 platform, the most powerful NFORCE2 400 Ultra series motherboard in chipset should be the focus of choice. In addition, SEMPRON 3100 based on the Socket 754 interface is not an advantage over price and performance, so it is not recommended by the author. In addition, you can refer to this topic for the purchase of the SemPron overclocking, you can refer to this topic: summer is like a fire! CPU cooling cooling scheme full Raiders!
