Asus P3V4X/S370-133/Tualatin 1.2Ghz


I am trying to install a Tualatin 1.2Ghz cpu (1.45v) on an Asus P3V4x motherboard using a Asus S370-133 rev 1.01 adapter.

I set the mobo in jumper free mode (JEN pins 2-3 "'ON'') and DIP switches U12 are all ''OFF''.

DIP switches on S370 are set to DEFAULT (1-2,1-2,1-2,1-2,2-3) and the cpu type(J6) is set to 1-2(coppermine).

I use BIOS version 1006.0004.

When I power my PC there is no BOOT, I only get a black screen(in DOS).

Is there a solution to this problem?

Thanks in advance.

    I am trying to install a Pentium 3 1.4GHz Tualatin CPU in my old, but trusty, Asus P3V4X motherboard. However, the system frequency multiple is locked at 6.5x and I need to have 10.5x to run at 1.4GHz. Therefore when I am running with a FSB of 133MHz I can only get 866MHz. I know that CPUs may be locked, but why would it be locked at 6.5x when its specifications (per Intel) are to run with a frequency multiple of 10.5x with a FSB of 133MHz? I do have the latest BIOS rev.

    Any help would be appreciated. I use a laptop for my daily work but I wanted to “revive” this computer of mine and put the fastest CPU in that I could. If this works then I’ll find some deals to increase the memory and video for cheap. Here are some other details:

    Motherboard: Asus P3V4X

    -Rev: 1.02

    -BIOS version: 1006.004

    -Jumperfree Mode

    -CPU Vcore: 1.45V

    Slocket: Slot 1 to Socket 370 adapter: Upgradeware Slot-T (rev 1.1)

    -CPU Voltage (JP1): 1.45 V

    -FSB (JP2): 133 MHz

    CPU: Pentium III-S 1.4 GHz

    -sSpec Number: SL6BY

    -512MB L2 cache

    -133 MHz FSB

    -1.45 V

    -I actually have six of these CPUs and the multiplier is locked at 6.5x on all of them.

    -My previous CPU was a P3 533MHz Coppermine EB (133MHz FSB, Slot 1).

It turns out that while the BIOS will not appear to recognize the Pentium 3 1.4GHz Tualatin CPU (SL6BY) in my Asus P3V4X motherboard, Windows XP does! I apologize for my delay in posting this.

I have five extra SL6BY processors that I'd like to sell if anyone is interested. I need to make some money to upgrade the memory in this antique to 2GB (turns out that low density 512MB RAM does work in the P3V4X, by the way).

The ASUS slocket will not support the Tualatin cpu unless it is adapted for use. You could try a tualatin to s370 adapter in your asus slocket to make it compatible. As the P3V4X has no native support for the cpu either it will not recognise the cpu as a tualatin. My P3V4X sees tualatins as PII cpus.

You must use SLOT-T adapter for Tualatin CPU on the MB ASUS P3V4X. And i oc 133MHz 1.8V to 1.6G, very stability.

Motherboard p3v4x : during bootup i get a system

This error is usually caused by an incorrect setting of either bus speed or multiplier (or sometimes processor chip operating voltage). These could be set either by software ie in BIOS or by changing tiny switches mounted on the motherboard.
Have you consulted your motherboard manual?
Try here:
or try the ASUS website and look under support or the discussion forums.
This will help:

These freq and voltage settings are set under BIOS which is usually accessed by hitting the DELETE key on your keyboard after turning on your computer.
Sometimes a quick fix is to enter BIOS as per the above instruction and selecting LOAD BIOS DEFAULTS or something similar to that and then save and exit BIOS and allow the computer to reboot.. That may get you to the point of booting up without the improper freq comb error.
If you have no luck playing with the above info, shut down your computer and remove the left hand side cover on your computer box or tower, so you can access the inner workings of your computer.
Remove the cooling fan from your processor chip. It will be a large square or circular (black or silver colour).
Take a look at your processor chip. Note the part number printed on the chip, which is only visible after you remove the cooling fan. For example it may say for example SL52P or something else. It may also be an AMD chip.
Search the internet for its specifications ie search for SL52P.
For example, if it was a Pentium 3 chip running at 800 Mhz go to google and search for specs of P3 800 Mhz processor with the part number SL52P.
Google returns the following info (based on the example above) of:
ie its a chip that runs at 800Mhz speed with the memory running at 133 Mhz (800 mhz processor speed obtained by having the multiplier set to 6 but actually means the memory is running at 133 MHZ but the processor running at 6 times the speed of the memory bus ie 133x6=800 MHZ (one of the settings you need to get right in your BIOS settings)
So if you had this chip, in BIOS you would select 133 bus speed, with the multiplier of 6 usually locked down on the processor physical internal wiring.
If your BIOS doesnt allow you to play with the processor and memory bus settings (commonly done to make the processor overclock to a faster speed) the other option is that you have the DIP switches on your motherboard set to the wrong settings. Again, refer to to your motherboard manual. The DIP switches are tiny plastic switch blocks on the motherboard with a row of (usually) white sliding switches.

Soyo SY-7VMA-B -supports P-3 tualatin (.13u) CPU's?

when looking for a cpu for the socket 370, be sure to NOT get the socket 370 cpu that is made for servers.

this type requires a motherboard made specifically for that type cpu.

use a search engine to find out how to tell if it is a socket 370 server CPU, there is not enough space here for me to explain it.
in that search you will also find out how to determine the answer to your question about cpu's supported by that motherboard..

most socket 370 based systems run pretty well, so you have a good machine there, and it's worth your time to keep it running, and to upgrade it.

When installing this card it has 26 pin conector at the top where do you connect on the mother board or somewhere else . The motherboard is an ASUS 3PV 4X


Onboard you have 6 white connectors, those are PCI connectors, you also have ONE BROWN connector, thats the VGA connector

You connect your vga-card on that brown connector (if it fits)

Good luck

Need help to set-up fcpga processe on asus P3V4X with asus-S370-L

Hi Neel, Are you running the board in JumperFree Mode? If so you shouldn't have to change any jumpers or dip switches. And the S370-L adapter card should NOT have to be set either, it should auto detect both processor core and voltage. If you don't know how to set the board up in JumperFree Mode let me know I'll walk you through it. If you ARE running in JF Mode then I'd contact Asus support. You have the right BIOS update to be able to support that proc but Asus had some issues with Intel chipset support with certain versions of the 370 adapter cards. (issues with both the S370-DL and the S370-L if I remember right) Let me know what happens, Dude
