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.

Athlon processor upgrade assistance:


Go to this link:

Select the model motherboard you have and click on the CPU support link, it will show you a list of CPU's that are supported. You have a socket 939 board and AMD CPU's are now AM2, AM2+ and AM3 socket, which are 940 pin. It may be difficult to find a new CPU for your motherboard that is new since they have not been made in awhile.

2600+ with ASUS MB A7V266-E/AA


Here is the CPU Support list from Asus Support, for the Asus A7V266-E,
http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=A7V266-E/AA&product=1&os=17

Scroll down the list. 34th one down, that is listed.

1.Did you get the Athlon XP 2600+ that has a 266MegaHertz, (MHz), Front Side Bus? (FSB)
The AXDA2600DKV3C?

There is an Athlon XP 2600+ that has a 266MHz FSB, and one that has an FSB of 333MHz. <-This one Won't work.
Model number ->AXDA2600DKV3D will Not work.
Both are Thoroughbred A/B Core models.

The AXDA2600DKV3C has a 12.5x multiplier.
Your 1900+ has a 12x multiplier. (AXDA1900DUT3C) They both have an FSB of 133MHz. (Shown as 266MHz because AMD processors are 'Double-Pumped')

A.The AXDC2600DKV3C will not work. It has a 16x multiplier. (Thorton Core)
B.The AXDC2600DKV3D will not work. It has a 333MHz FSB. (Thorton Core)
C.The AXDA2600DKV4C will not work. It has a 15x mulitplier. (Barton Core)
D.The AXDA2600DKV4D will not work. It has a 333MHz FSB. (Barton Core)
E.The AXDA2600DKV4E will not work. It has a 400MHz FSB. (Barton Core)

2.Are the jumper blocks -> CPU RATIO, and SYSCLK, still set in the Jumper Free Mode?

By the factory default settings these jumper blocks, (DIP switches), should already be set to Jumper Free Mode.
The white DIP switches should be in the OFF position. (The white switches will be DOWN, towards the numbers on the jumper block CPU RATIO. They will be UP, away from the numbers, on the jumper block SYSCLK))

The CPU RATIO jumper block is right above the processor. It is a blue rectangular block.
The SYSCLK jumper block is down the motherboard, right below the AGP graphics card expansion slot. (And above the first PCI expansion slot)

If those two jumper blocks are not set to Jumper Free Mode, set the DIP switches in the jumper blocks to this setting.

Now go into BIOS Setup. In the main menu use the Right Side Arrow key on your keyboard, and highlight Advanced.
If -> CPU Speed is set to Auto, you won't have access to set your CPU parameters. If it is set to Manual, you will see them. If it's set to Manual, write down the headings, (CPU:System Frequency Multiple, System/PCI Frequency (MHz), and so on) Write down the numbers to the right of these headings. If something goes wrong, you can go back into BIOS Setup, and change them back.

1.CPU:System Frequency Multiple should be
12.5X
2.System/PCI Frequency (MHz) should be
133/33
3.System/DRAM Frequency Ratio should be
(Auto)
4.CPU Vcore should be (1.750)
5.CPU Level 1 cache, and Level 2 cache should be (Enabled)
6.CPU Level 2 cache ECC Check should be (Disabled)
7.BIOS Update should be (Enabled)
8.PS/2 Mouse Function Control (Auto)
9.USB Legacy Support (Auto)
10.OS/2 Onboard Memory >64M (Disabled)

Leave the rest alone.

The AXDA2600DKV3C uses 1.65 volts, has a 12.5 clock multiplier, and a 266MHz FSB. (You will see 133MHz, and set all your settings to 133MHz. AMD processors are 'Double-Pumped'. Intel processors are 'Quad-Pumped')

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.

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.
