Upgrade from 600 MHz to 1 GhZ

IBM IntelliStation zPro came with different CPU chips through 1997 to 2006. Depending on which year or type your machine is will determine if you can upgrade to Windows8.

The chips used were

IntelliStation Z Pro

Type 6899 (March 1997 to ??)

• Dual Intel Pentium Pro at 200 MHz (50 MHz FSB)

Type 6865 (October 1998 to April 2000)

• Dual Intel Pentium II Xeon at 400, 450, 500 or 550 MHz (100 MHz FSB)

Type 6866 (January 2000 to March 2002)

• Dual Intel Pentium III Xeon at 677, 733, 800, 866, 933 MHz, or 1 GHz (133 MHz FSB)

Type 6894 (May 2001 to June 2002)

• Dual Intel Itanium at 800 MHz

Type 6221 (November 2002 to February 2005)

• Dual Intel Xeon at 2.4, 2.67, 2.8 or 3.2 GHz

Type 6223 (August 2004 to March 2007)

• Dual Intel Xeon with Intel 64 (formerly EM64T) at 3.0, 3.2, 3.4, 3.6 or 3.8 GHz

Type 9228 (June 2006)

• Dual Intel Xeon Model 5130, 5140, 5150 or 5160

Windows 8 If you want to run Windows 8 on your PC, here's what it takes:

• Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2 (more info)
• RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
• Hard disk space: 16 GB (32-bit) or 20 GB (64-bit)
• Graphics card: Microsoft DirectX 9 graphics device with WDDM driver

As you have Type 6223 which a Xeon faster than 1GHz it should work with Windows 8 but not all Xeon processors are compatible depending on which one you have. See this Microsoft site after you check your Xeon chip family on the motherboard or through the Windows system command. Search for xeon.

The fastest Pentium 3 that will work in your board is a Intel Pentium III 1GHz chip. Here is a link to the specs:

You could also get a Intel Celeron 1.1 GHz but it only has half the level 2 cache size so it's actually a bit slower than the Pentium III 1GHz chip.
Here's a link to celeron specs:

Unfortunately, these are old processors and I don't see any available new. Newegg.com lists a couple available as refurbished. You may be better off getting a new computer with either a Intel I3 or current AMD processor.

I wish that I had better news for you.

(do not attempt to use a CPU that your motherboard doesn't support. It probably won't boot.)

Hello,
The Intel® Desktop Board D845GVAD2 supports a single Pentium® 4 processor with a system bus frequency of 400 MHz or 533 MHz, or a single Celeron® processor with a system bus frequency of 400 MHz.

So you can install upto 3.06 GHz 533 MHz(cache memory) processor and also update the ram 2 GB 400 mhz.
Dont install Prescott processor.
Hope it will help you.

Some laptops have "mobile" CPUs (physically smaller, and consuming less power) than the typical "desktop" CPUs.

So, if you know "how" to disassemble your computer, you may be able to remove the heat-sink & fans on top of the CPU, remove the CPU, and install a faster one.

However, if your current CPU is of the "Pentium III" series (which ranged from 500 Mhz to about 1400 Mhz), you may not be able to find a CPU that will be significantly faster than your current 1.26 Ghz CPU.

Instead, I would check the disk-drive -- if it is 4200 RPM or 5400 RPM, I would replace it with a 7200 RPM disk-drive, for better I/O speeds, and thus help your computer go "faster".

Also, I would add more RAM, again to make your computer go "faster".

You are basically limited to what was optional on the model. So you can only upgrade to one of the following cpus:

Intel Pentium M 745 (1.8-GHz) with 400-MHz front
side bus (FSB)
Intel Pentium M 735 (1.7-GHz) with 400-MHz FSB
Intel Pentium M 725 (1.6-GHz) with 400-MHz FSB
Intel Pentium M 710 TJ85 (1.4-GHz) with 400-MHz FSB;
operates at a lower temperature than other processors
Intel Celeron M 340 (1.5-GHz) with 400-MHz FSB
Intel Celeron M 330 (1.4-GHz) with 400-MHz FSB

And you are limted to 2gb of ram max on this model.

here is a list of processors supported on that machine

Intel Pentium M 745 (1.8-GHz) with 400-MHz front
side bus (FSB)

Intel Pentium M 735 (1.7-GHz) with 400-MHz FSB

Intel Pentium M 725 (1.6-GHz) with 400-MHz FSB

Intel Pentium M 710 TJ85 (1.4-GHz) with 400-MHz FSB;
operates at a lower temperature than other processors

Intel Celeron M 340 (1.5-GHz) with 400-MHz FSB

Intel Celeron M 330 (1.4-GHz) with 400-MHz FSB

Your motherboard supports 2 different fsb's.
look these up @ cpu-world
you can use:
Intel Pentium 4 processor (478-pin)
- 533MHz system data bus - supports up to 2.8 GHz
- 400MHz system data bus - supports up to 2.4 GHz

Intel Celeron processor
- 400MHz system data bus - supports up to 2.0 GHz CPU speed
and here are the suppoted cpus:

you could only upgrade the processor and RAM in this condition i.e.

you can only change your an upgraded p-III processor like 1.0 GHz, 1.1 GHz or 1.3GHz and
upgrade the RAM by changing to 256 in each slot.

that is all what u can do with ur pc

Hi, For Dimension 3000 system here are your options. Pentium IV 3.2 GHz 533 / 800 MHz FSB Pentium IV 3.0 GHZ 533 / 800 MHz FSB Pentium IV 2.8 GHz 533 / 800 MHz FSB but what i'm worried about is the socket where the process goes into. for thermal issues it is expected for the socket to CHIP CREEP. Chip creep refers to the problem of chips that, over time, would work their way out of the socket. Chip creep occurred due to thermal expansion; the contracting and expanding during system heat up and cool down. you might end up replacing the mobo as well.
