In all the accessories of the computer, the motherboard is one of the easily failed devices, which leads to a lot of factors, where the motherboard itself is a key. For these, many motherboard manufacturers also provide new BIOS program to solve compatibility issues. Despite this, in such a complex level of hardware technology, it is not only a soft method. In order to let everyone master the consequences of the motherboard BUG, and how to solve these problems, this article lists the common bugs of KT600, 865PE and NFORCE2 motherboards on the market, and make reasonable solutions for this purpose!
Advertising: D_text [B] 1, KT600 Common BUG and Solution [/ B]
[b] 1, PCB design bug [/ b]
Although the KT600 is VIA as the last AMD motherboard spindle product based on the KT400 series (Figure 1), in addition to the South Bridge VT8237, there is not much difference from the previous KT400A, so Some compatibility and performance defects in KT400A, still see some footprints on KT600.
The first is the main board PCB layout, because many low-end brand KT600 still use KT400A's PCB, so the motherboard is working, because some tiny metal conductors are accidentally falling on the motherboard, very likely to cause short circuits, author The KT600 is because the static electricity of the TV card is burn broken, and the TV card has not happened in MSI MSI6199 old motherboard for 1 year. Therefore, be careful not to let the conductive object contact the motherboard PCB. Of course, this fault may be an exception. After all, static or short circuit will bring harm to any motherboard. Then, the compatibility of memory, the KT600 has three memory slots, but it is said that only 2 DDR400 is inserted, there will be only one phenomenon, but this phenomenon has not been encountered on the 8krai of the author.

[b] 2, driven bug [/ b]
Secondly, the problem of driving, the VIA motherboard has not solved compatibility in driving, leading to low disk performance, compatibility, and stability are guaranteed, KT600 is not so, especially don't properly install immature drivers, such as Hyperion V4.49VP2 driver, this driver has a large bug, which will cause the system to restart the hard disk error 'Blue screen hard disk error, and the reinstalry system result partition cannot recognize the fault, and the internal integrated IDE driver is very large. The problem (including 4-in-1 4.50), so everyone should install the latest mature Hyperion 4-in-1 driver (Figure 2), such as VIA VIA HYPERION 4-IN-1 latest driver 4.55 version correction is in some The problem of DELAYED WRITE (delayed writing) in the KT600 appears in a specific environment, and there is also a good improvement in the performance of the disk and SATA hard disk. And you can solve some compatibility issues during some use.

[b] 3, BIOS's bug [/ b]
The final serious problem is BIOS, the SATA function added by the South Bridge VT8237 is not very mature, the boot detection speed is very slow, it takes a long time, and many users have found that WinXP cannot be installed with the SATA hard drive, which is not only due to technology. Not mature, and because BIOS also has a BUG. The problem of solving is to upgrade the latest motherboard BIOS, such as the author's Zongzheng 8kRai, and install the S-ATA driver restart on the Windows ME system. There is no normal shutdown issue after replacing the IDE hard drive, and once the dead or system is wrong, the BIOS will automatically return to the default state. If it is the KT600 before October 2003, it may not be able to identify the Barton, Thorton core, and Applebred core CPUs, let alone identifies the latest AMD Sempron.
However, the motherboard manufacturers have developed the latest BIOS for our upgrade. After upgrading the BIOS, they will basically solve the above problems. After the author upgraded the BIOS, increase the AMD Sempron CPU self-test information code, improve the compatibility of the FSB400 CPU, Improve SATA support attributes, increase SATA IDE enhancement channel mode (Figure 3). The VIA 6420 serial ATA adapter ROM version is upgraded from V0.97 to V2.20 (as shown in Figure 4, Figure 5), and the boot speed is improved, and the performance is also improved. So, the KT600 motherboard user, you need to pay attention to whether there is a new BIOS to appear, and some will be updated immediately.

[b] Second, NFORCE2 Common Bug and Solution [/ B]
[b] 1, bug [/ b] of the memory trough design
Some NFORCE2 motherboard memory slots have problems. For example, when the MSI's motherboard uses two-sided memory, if the memory is plugged in in the second slot, the NFORCE chipset memory can be caused by 20% -25%. This is because the NFORCE chipset introduces the Twinbank memory architecture, such as the MSI's NFORCE motherboard, MSI to design the second memory slot design that the second Bank's B slot location of the chipset, and NVIDIA official itself is the first Three memory slots use the second Bank's B slot, and usually we interpose DIMM1 first, then insert DIMM2, so there is more problems in this motherboard (Figure 6). After this problem occurs, we only open the SuperStability mode or not using the third DIMM slot.

[b] 2, memory compatible BUG [/ b]
NFORCE2 motherboard is relatively poor, especially Kingmax memory, because Kingmax uses TinyBGA package, but TinyBGA packaging processes require strict memory specifications, which may result in playing 3D games in NFORCE2 in NFORCE2 in some specification, etc. Especially Kingston granules), this is completely design issues that belong to NFORCE2 motherboards. In addition, in dual-channel operating mode, if the memory of different capacity of different brands, there will be more weird phenomena in addition to the above faults. Therefore, when you purchase memory, you should pay attention to it, generally choose Kingston's DDR333 (Infengnion particles) and DDR400 (WinBond particles) and Samsung's original memory, NFORCE2 motherboard users are best to [URL "before purchasing memory = http://www.nvidia.com/content/nforcememorycompatability/lstnforceMemoryCompaMPAMPAMPAMPAMPAMPAMPAMPAMPAMPAMPAMPAMPAMPATILITY.ASP]

[b] 3, USB2.0 compatibility BUG [/ B]
NFORCE2 brought light with powerful performance advantages, but considering performance, there is no much consideration, causing most NFORCE2 motherboards to have a lot of bugs, which is the most common is USB2.0 compatible problem, usually we are in USB 2.0 Using USB1.1 device on the interface is no problem, but only the speed of USB1.1, but many USB1.1 devices have compatible problems on NFORCE2_MCP-T and MCP motherboards, such as Sigmatel chips. Equipment, using the USB device using Sigmatel STMP3410 can improve compatibility by refreshing FireWare (Note: These devices must refresh FireWare under non-NF2 systems, otherwise refresh will fail!). As another genesys chip-based device, an error occurs when using GeneSys GL811 in a copy greater than 20MB file, and the device disappears in device management (as shown in Figure 8), the solution is to install the latest V2.00 or more version drivers.

Figure 8, NFORCE2 motherboard USB compatibility list
In addition, from the current point of view, the best use platform for nForce2 is WinXP SP1 or Win2000 SP3 (less chances to have problems). Win9x is not very good because of the support of USB2.0, so it will not use normal use. The phenomenon of USB2.0 device; the NFORCE2 is relatively high, and the general 250W power supply is in use (especially multi-ROM and multi-hard disk users) may be more difficult, recommend everyone to use more than 300W, which can avoid a lot I didn't have problems.
[b] 4, BIOS's bug [/ b]
BIOS is the basis of the motherboard. Almost many motherboards have problems while upgrading BIOS can be resolved, such as compatibility issues for nforce2 chipsets and partial PS / 2 peripherals, resulting in PS / 2 mouse and keyboard unwill, generally Solve by upgrading the BIOS. In addition, in some nort2 motherboards, if the outer frequency of the CPU is different from the outer frequency setting (such as the CPU is 200MHz, the internal memory is 166MHz), the system is unstable, which is a large NFORCE2 motherboard BIOS. BUG, that is, when memory is synchronized with the CPU, it can play its greatest performance, but not synchronization is caused by the above fault, sometimes using the network card connection built into the chipset, there will be a slow start speed, which is due to nForce2 motherboard The built-in network card in the South Bridge chip has caused conflicts, but as long as the latest BIOS can solve the above fault, such as EP-8RDA3 upgrade the latest BIOS, the new brand specification memory is added (Figure 9).

[b] 5, board network card BUG [/ b]
Some early nForce2 motherboards (such as 8rda ) onboard network cards have problems, which can only be sent to use ADSL, can not be received, some netizens put forward the solution below WinXP: Double click in "Device Manager" Network adapter, select advanced options in the Properties window, with a "Connection Type" to change its value to the second item. But this method may be invalid for some motherboards. The best solution is to specify an IP for your onboard network card. This will no longer find the server when the machine enters the system, and the use of broadband friends don't have to worry, specified this IP It is the local EtherNet Adapter IP, and the PPP Adapter ADSL IP used in the broadband is non-broadband, so the specified IP does not affect the broadband.
The method is to right-click the online neighbor (in win2000 as an example), select "Properties", right-click "Local Connection", select "Properties", select Internet Protocol (TCP / IP), click "Properties" below, Select "Use the IP address below", in the corresponding column, enter the number in Fig. 5 (the X may be any number between 1 to 255) between 1 to 255), press "OK" (as shown in Figure 10). Restart, problem solving. If you specify IP under Win98, start it slowly, you can try to shield your own IEEE 1394 card in the control panel.

[b] 6, the bug of the plate sound card [/ b]
Some acoustic cards and nForce2 on the market have compatibility issues, and there is a compatibility issue with the acoustic cards and nForce2 conflicted with the VIA chipset. In addition, the population is a biggest problem with the nForce2 motherboard. For example, the EP-8RDA3 will have a BSOD error when loading a DLS file, and the system is unable to listen, in which the population settings 6 sounds are more prominent, so we You can't use 5.1 good speakers, and there are also game NOLF sound errors. In addition, the NFORCE2 motherboard's hard drive will fail to start or crazy, and the compatibility of the burner also has problems, and this problem is mainly NFORCE2 disk drivers are related to, of course, we can solve these problems as long as we install the ForceWare driver 3.43 or higher. [b] 7, other bugs [/ b]
In addition, the temperature detection of the BIOS is achieved by the thermal probe on the motherboard, and the probe position of different brands NFORCE2 is different, but it is almost certain that NFORCE2 is currently detected in the BIOS. Differences, with 8rda as an example, the temperature measured in the BIOS is about 10 degrees lower than the actual low, so everyone will open the overheated protection function in the BIOS when overclocking, so as not to cause unnecessary losses.
Some nForce2 motherboards (such as ASUS A7N8X) a jumper setting identified as KbpWr1, the default is 1-2, which can be changed to 2-3 to implement the keyboard / mouse boot, this feature requires your power quality to be too hard, If you find any abnormalities after opening, turn off this feature.
Finally, many friends reflect the compatibility of nForce2 and compatible compatibility, especially when using Nero, when using Nero, I have some resolution, here there is some solution, first to ensure that ASPI Layer is already installed on your system, then Install the latest mature stable version of IDE driver, then set your recorder to master (primary disk), if you still don't work, set the recorder's mode to PIO (this will affect performance).
[b] Third, 865PE Common BUG and Solution [/ B]
[b] 1, bug in chipset [/ b]
Basically, the 865PE motherboard is less than the above two problems, but there are many exceptions, such as MSI MSI 865PE NEO2 series motherboard, after the overclocking attempts, once the overclocking fails, in some cases, even if the CMOS is discharged It cannot be started immediately; the CPU's monitoring report is high and cannot be used, and if the Windows 98 operating system is installed, the APIC SCI IRQ Device; the BIOS is available in the BIOS only 2 and 2.5 two gear options. For such a problem, you can try to upgrade the latest BIOS to resolve (Figure 11). If the upgrade BIOS can't resolve, only the manufacturer replaces the motherboard. In addition, I865PE is equipped with support SATA RAID0 in the ICH5R chip, such as in Windows XP, not properly set and install driver correctly, the operating system will have a blue screen that cannot be installed. Therefore, when you do not use the RAID function, turn off the RAID function. When you use RAID, press the F6 button when you install the operating system, then insert the floppy into your computer, you can manually add the RAID controller driver (before you need to download the latest RAID driver from the official And copy into the floppy disk).

In addition, many users have found recent Intel 865pe chipset motherboard rework rate linear, and the rebound problem is not limited to a brand, and many brands of 865PE motherboards have similar problems. Most of the failure of the returning motherboard is that the South Bridge chip is burned, resulting in a normal boot. And coincident, these damaged motherboards are using the USB device when there is a problem. When the manufacturer announces that this kind of thing is best to insert the USB device, it is best to release static electricity. When inserted into the grounded metal release static electricity, then touch the metal portion of the USB plug to release static electricity through the human body.
[b] 2, board network card BUG [/ b]
For advanced users need, some I865PE motherboards (such as the upgraded I865PE IS7, Qing Yun PX865PE PRO, etc.) have built-in 3COM Gigabit NIC (Figure 12), but according to an authors, when using its built-in NIC Internet card, there is often a network After the line is unstable, but after the built-in network card function, use the ordinary PCI network card, but there is no such problem, so there is a user of this type of motherboard. If you don't have a network card, it is best to close the change in BIOS, or With a PCI network card, of course, you can try to upgrade the BIOS to resolve this issue.

[b] 3, Hyper-threaded bug [/ b]
We know that Hyper-throwing technology has brought the performance of performance, but not all software can support this technology. For example, in Win98 / WinMe, you can't play the advantages of HT technology, in addition, Hyper-Threading Hyper-Threading Technology in WinXP There will be some abnormalities, such as by default, if Hyper-Threading (as shown in Figure 13) is turned on, sometimes the Windows XP system performance will drop, and later Microsoft also confirmed that the SP1 patch still has some execution error. For example, the Pentium4 processor with HT function and the function is turned on normally. In the Windows XP operating system installed on SP1 (Service Pack 1), an error occurs when a program is executed, and the phase of the error is when the big layer file is opened. The system is suddenly lowered when the two processors identified by the HT technology are coordinated. In addition, HT technology has a significant decrease in IE6 compatibility. After opening HT, IE browsing speed is significantly dropped, but the latest patch or third software in Microsoft can solve these problems, and everyone will pay more attention to these messages.

[b] 4, BIOS's bug [/ b]
It is also worth noting that there are many controversies for 865PE PAT technology, then Intel shields the technology, although Intel shields this feature, but many brand motherboards such as MSI, Asus, Sheng Team, etc. I have developed one. Set of new features similar to PAT technology. ASUS called "Hyper Path", which "Hyper Path" is called "hyper path", and the Game Accelerator is called "MAT". But many 865PE motherboards do not have these special features. In fact We can get this feature by upgrading BIOS. Take the MSI main board 865PE NEO2-S (MS-6728) as an example, by upgrading the latest BIOS version provided by MSI official website to implement the MAT function. MAT can optimize the CPU, North Bridge, Data transmission efficiency between memory, effectively improves memory performance, expands 10% of memory bandwidth, so that itself reaches 875P. After upgrading BIOS, under the BIOS settings interface, enter the "Voltage and Frequency Control" option, we can see Performance Mode option (Figure 14), this is the hierarchical directory of Mat! Enter the PERFORMANCE MODE option, which can be found that this is a MAT function option has several modes, where Turbo and Ultra-Turbo are used to improve memory performance (as shown in Figure 15). ) If you choose a Ultra-Turbo option, then its acceleration effect is the strongest.

In addition to this, some early 865PE motherboards have a defect for hard drives, which is the default, there is no smart function that opens the hard disk, causing a healthy status of the hard disk that cannot be effectively monitored, this is a bug in the BIOS, However, almost all brand motherboards provide the latest BIOS upgrade to get this feature. If you can't find "S.M.R.T." in your 865PE motherboard (as shown in Figure 17), you can go to the official website to see if there is a BIOS upgrade of S.M.R.t. option. If a friend of the author After upgrading the BIOS, there is a "HDD S.m.r.T. Capability" feature option in the BIOS setting, as long as it is set to Enabled, it can be opened (Figure 17).
