Question about Soltek SL-75FRV Motherboard

1 Answer


Just upgraded cpu, bought the amd athlon xp 3000+ with front side bus 333mhz. My board is the VIA Apollo KT400 series Socket A which supports the FSB with this processor, my problem is that when the computer starts, the speed is displaying 2800. I altered the jumpers on my board for the cpu clock to 166mhz which is what it's supposed to be and is showing this correct in the CMOS setup utility. Also in CMOS the processor speed is correct, reading 2167 but when computer boots, the speed is displaying 2800+ when it's supposed to be 3000+ I've been told that the motherboard's bios doesn't recognize the processor and that I should upgrade the bios. Is this correct, if so, how do I do this?

Hi, I have to agree "...that the motherboard's bios doesn't recognize the processor and that I should upgrade the bios...". Though I think that this is only a display issue and not necessarily true CPU speed. You can check if the correct CPU is displayed inside Windows by right click on My Computer and details would be shown in the System Properties. To upgrade the BIOS: 1. Determine/log your current BIOS and its date by pressing Pause on initial boot when motherboard details are shown; 2. Continue booting by pressing escape and run your Windows normally. Go to the website of your motherboard manufacturer and verify if they have an updated BIOS (compare date of release). If an updated BIOS is available, download. Likewise download the flashing utility. Further instructions are also available on a step by step procedure. Some newer mb versions/models have a Window based update feature. Check if you have such. Hope this be of some help/idea. Post back how things are or should you need further information. Good luck and kind regards.

I'm upgardeing my ms-7061's cpu from a 1.5 to 2.2

Supports AMD Athlon / Athlon XP / Duran (Socket 462) processor.
(Socket 462 = Socket A)

Supports from 1100MHz to 3000+ model.

VIA KM266 Pro motherboard chipset - Front Side Bus support of 266MegaHertz.

(Same specs as a VIA KT266A but with Integrated Graphics.
The 133MHz FSB support shown is doubled. AMD processors are 'Double-pumped')

VIA KM400 motherboard chipset -
FSB support of 266MHz to 333MHz.
(Same as KT400 but with Integrated Graphics)

VIA KM400A motherboard chipset -
FSB support of either 266MHz, 333MHz, or 400MHz
(Same as KT400A but with Integrated Graphics)

Looking at the Bottom/Right corner at the CMOS battery;
There are THREE sets of jumper pins to the bottom right edge of the CMOS battery.

6 pins towards the outside edge of the motherboard, 3 pins to the inside of the motherboard. (Left side of the 6 pins)

On the 6 pins in a row configuration, the top 3 pins is SW1.
The bottom 3 pins is SW2.
The 3 pins to the inside of them is JBAT 1

In the 3 pins for SW1 the bottom pin, or pin closest to the bottom edge of the motherboard, is Pin 1.

Same for SW2. The bottom pin, or pin closest to the bottom edge of the motherboard, is Pin 1.

Jumper on pins;
SW1 pins 2 and 3, SW2 pins 1 and 2 = 266MHz FSB support
SW1 pins 1 and 2, SW2 pins 1 and 2 = 333MHz FSB support

For the KM400A (KT400A) motherboard chipset;
SW1 pins 1 and 2, SW2 pins 2 and 3 = 200MHz FSB support

1) What is the model name, and model number of the AMD processor you are going to use?

2) What kind of Thermal Paste are you using?

3) What are you using to clean the bottom of the Heatsink with, and is the top of the Processor clean?

4) Are you following Anti-Static Precautions?

Can I upgrade my 1Ghz processor to a faster 2 or 3Ghz? I have an EliteGroup 741GX-M, socket 462 desktop with an AMD sempron

yes, it is possible, but the Front side bus will limit the functionality so much that it wouldn't be worth it.

I need a m7vig400 supporting prossers

You can see the supported CPU list from Biostars web site;
Listed under Model. Scroll down the CPU list untill you come to M7VIG 400. Highest CPU supported is, AMD Athlon XP, 3000+ (333MHz)
Main web site for the M7VIG 400;

List of possible CPU's; AMD Athlon XP 3000+ - AXDA3000DKV4D;

Hope you find this helpful.

2600+ with ASUS MB A7V266-E/AA

Here is the CPU Support list from Asus Support, for the Asus A7V266-E,

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
2.System/PCI Frequency (MHz) should be
3.System/DRAM Frequency Ratio should be
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')

Changed cpu on an abit va-10 mb but the fsb stays at 266

Unless the mobo is compliant with a front side bus speed of 333mhz, the cpu you have will only run at 266mhz max, in other words the cpu will down-clock to the 266mhz bus clock and therfore run more slowly. check with the mbo handbook, or on CMOS tosee if yoy can change the fsb setting. ask for more help if needed.Can you give me the full code of the mobo ?

I have AMD Athlon XP 2200+ m7vit bravo m-b

All current 333 MHz capable Socket A chipsets (VIA KT333, KT400, nVIDIA nForce2, SiS 746FX) should be compatible with Barton based processors although you may need to flash the BIOS for the processor to recognized properly
your board has a 333mhz front side bus so should be capable of running them
You must ensure that the cpu is for 333 mhz and not more and that it fits socket A which your board is
Please post rating thanks

Upgrade my processor

You can use either an Athlon, Duron, or Athlon XP processor, with a max front side bus speed of 266 MHz. This is slow compared to today's standards. Most of today's newer processors have front side bus speeds of more than 2 GHz, about 8 times faster.

CPU Upgrade

Athlon XP 3000+ is 400mhz FSB according to the link(,,30_118_1274_3734^11672,00.html), means that in order to display the actual speed of your Athlon XP 3000+ you have to set your board 166mhz to 200mhz jumper setting or in CMOS utility overclocking option. and also just to inform you that your motherboard is in Overclocked condition when set, because it only supports processors up to 333mhz FSB (
