Problem with PCIX 133MHz slot

Hi, I've installed the Lava DSerial-PCI 1.3V in a 100MHz PCIX and it is working fine. But when I try to install the board in my 133MHz PCIX slot, it is not working. In Device Manager, there is a "!" on the device and and it written it is a code 10 and that the board won't start. Can you help me on that ? thanks

IBM T23 wont turn on after adding new RAM

Hi - according to memory suppliers your T23 has the following memory capacity / requirements:

  • IBM ThinkPad T23 maximum RAM capacity: 1GB
  • Your IBM has Two (2) memory slots or sockets
  • Module upgrade PIN count is: 144-PIN
  • The memory speed is: SDRAM 133MHz, PC133
  • The laptop DIMM type for the ThinkPad T23 is: SODIMM, SO-DIMM, Small Outline DIMM
  • Non ECC

If you are meeting these requirements, you may have a defective module.

Also, according to Lenovo's page on the machine:

The system has 128MB or 256MB of memory standard and can be configured for up to 1GB of addressable memory. Memory options up to 512MB SDRAM SO DIMMs each can be added in the two available slots for memory expansion. The standard 128MB of memory is expandable up to 640MB and the 256MB of memory is expandable up to 768 MB of addressable memory with 64, 128, 256, or 512MB SO DIMMs without removing the 128MB SO DIMM that is standard in one of the internal slots for memory. For customers that need the maximum 1GB to which memory can be expanded, it is necessary to replace the 128MB or 256MB card with a 512MB card plus add another 512MB card in the extra slot. Only 133MHz DIMM memory can be used in this system. The use of 100MHz DIMM memory is not supported in the T23 systems.

This means yo can trouble shoot the 512MB modules individually by installing one of the original 128MB modules and one of the new 512MB modules (for a total system memory of 640MB). If it does not boot, try again with the other 512MB module. This will help you identify a defective module that may be preventing the machine from booting.

I hope this helps & good luck!

What is max new cpu speed to change for old cpu ? k7sv266ad

The KT266A is a VIA motherboard chipset,

The motherboard chipset for your motherboard, consists of a Northbridge, and Southbridge chip.

The Northbridge is a VIA 8366A
The Southbridge is a VIA VT8235

CPU = Central Processing Unit. Another term used is Microprocessor, or Processor for short ]

The Northbridge chip handles the faster capabilities of a computer.
Handles the Processor, Ram Memory, and HIGH-speed graphics.

[A graphics card installed into a PCI expansion slot is Not high-speed graphics.
Integrated Graphics is Not high-speed graphics.

AGP and PCI Express are high-speed graphics.
If you have an AGP graphics expansion slot, it is handled by the Northbridge chip.
If you have a PCI Express expansion slot, it is handled by the Northbridge chip ]

The Southbridge chip handles the slower capabilities of a computer. This is shown in the diagram.

The VIA KT266A's Northbridge chip, (VT 8366A) supports AMD processors with UP TO a 266MHz Front Side Bus.
(266MHz FSB)

In the chart you see under the FSB heading -> 100 - 133MHz
100MHz to 133Mhz.

AMD processors are 'Double-Pumped'.
Therefore 133MHz becomes 266MHz.

233Mhz with the jumpers at their present positions?


Looking at the motherboard, as it is mounted in the computer case; Processor to the Top, Ram Memory slots to the Right,
5 White PCI slots to the Bottom;

The J4 jumper is above the CMOS battery.
The CPU Frequency Select jumper.

(The J1 jumper is right next to the CMOS battery. To the left. That is the Clear CMOS jumper)

The jumper has 3 pins. Number 1 pin is on the LEFT.
From Left to Right; Pins 1, 2, and 3.

With a jumper block,

,on Pins 1 and 2, you have a 100MHz FSB.

With a jumper block on Pins 2 and 3, you have a 133MHz Front Side Bus.

Processor you pick have a broken pin?

You can use AMD Athlon processors with up to a 133Mhz FSB, or AMD Duron processors with up to a 133MHz FSB.

[Actually 200MHz FSB, and 266MHz FSB. Remember what I stated about Double-Pumped ]

No display on DL380 g4

This can be caused by a processor / VRM issue or even a system board fail. Try dropping to a single proc and VRM and swap test with the others.

Unsure of what type of PCI expansion slot in dimension 2400

8 and 16 bit PCI slots haven't been used in years so your slots would be 32 bit unless your PC is extremely old. That card will work fine.

PCI Express slot, eight beeps

Yeah, but it's not the slot; it's the northbridge chipset or a PCI bridge driving it that's perhaps overheated or set funny.  If you use 2 CPUs they can fall out of step several ways, or your clock circuits can age badly by themselves!  Got fresh CMOS batteries in there?  It could be that PCIe was merely asked to run at a frequency it won't run.  You should carefully make sure the board is nice and clean, reflash or at least clear settings on the BIOS, confirm the PCI videocard boots, make sure all the chips are cooled well, and again see if you can get a PCIe card to work without complaint.

Starts without ram but not with ram

The FSB jumper is not for the memory. It's for the CPU.

Set that back to 100mhz and try it again.
