Question about ASUS Intel 845 Chipset P4B (P4B WOA) Motherboard

1 Answer

Advance Bios Set up (CPU frequency (MHz) setting)

My computer has started to run extremely slow (suddenly) for about 2 days, and has become more and more slow each day. The startup is very slow now and when I start using some applications the CPU usage is at 100% for a long time. I initially thought it was my RAM but I already have 1GB ram so it shouldnt be the problem (since the computer just suddenly became slow for 2-days).

Today while i was transferring a file from one drive to another my computer suddenly switched off half way through the transfer. When I tried to power it on again i get taken to the Advanced bios menu, and the CPU frequency (MHz) was highlighted and the message on the right says along the lines i need to choose the correct setting. But I dont know how to determine what number to choose. The value I can choose is 100-200 MHz but not sure which is correct. I now left it at 100Mhz is this the cause of my computer being very slow?

Your computer is telling you there is a problem with either the memory or the interface between the motherboard and the memory. There is a utility you can use called memtest. I would run that and see if you get errors. Often it is easier to simply try a different piece of memory in the slot, because even if you detect errors it could be due to the interface and not the memory itself.

But the first thing you should try is power off the computer, remove the cover, blow all the dust from inside the case, remove the memory and blow all dust from the memory sticks and slots, then put it back together and try again. This is free and solves the problem about 20% of the time.

Good luck.

Computer will not let me change cpu frequencies


Sounds like an old motherboard or CPU. Some have auto sense and will not let you overclock it no matter what you do.

Flash video: make sure you the most up to date adobe flash player from their web site. Some flash players may have operating requirements that may exceed your CPU, memory, video card.

Cpu clock in my bios read only from 1200 to 1600 mhz.


Please read carefully the chapter 2 (page 33 and 47) of User's Manualfound at:
http://support.asus.com/download/download_item.aspx?model=P4S8X-X&type=Manual&SLanguage=en-us

I suggest you select "Auto" on "CPU Speed" setting in the BIOS "Advanced" Menu or adjust 18x in "CPU Frecuency Multiple" if posible for reach optimal setting.

Increasing of FSB (processor clock) from 10% up to 15%.
from 1700Mhz you can get 1850 Mhz.
from 2400 Mhz you can get 2640 Mhz
from 3000 Mhz you can get 3300 Mhz
but not all mater board allow this do.

RAM not running at full speed


Go to page 33 in your manual, see DRAM Clock/Drive Control & press enter. You can tweak your memory to run faster however your manual suggest not too. Hate to see you burn it up. As you will see everything is set to Auto:
Max Memclock (Mhz) [Auto]
1T/2T Memory Timing [Auto]
CAS# latency (Tcl) [Auto]
When DDR Timing Setting by is set to Manual, use this item to set the DRAM frequency. Would be nice to have a side panel fan blowing on your memory.

4 x 1GB DDR400 installed; only 3GB recognized by MOBO


If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as: - System BIOS (including motherboard, add-on cards, etc..) - Motherboards resources - Memory mapped I/O - configuration for AGP/PCI-Ex/PCI - Other memory allocations for PCI devices Different onboard devices and different add-on cards (devices) will result of different total memory size. e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses. On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices. This limitation applies to most chipsets & Windows XP 32-bit version operating system. If you install Windows XP 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met: 1. The memory controller which supports memory swap functionality is used. The latest chipsets like Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture can support the memory swap function. 2. Windows XP Pro X64 Ed. (64-bit) or other OS which can address more than 4GB memory.
