http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00297771&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=443756The Asus PTGD1-LA motherboard, is a Proprietary motherboard, made Especially for HP.
HP's name is PufferM-UL8E
You won't find it on the Asus Support website.
Fortunately, HP listed basic information for CPU (Processor) Support.
When you look to the right of the CPU/Processor heading, you can see it states -
A) Socket LGA 775 (Processor socket)
Looks like this,
http://en.wikipedia.org/wiki/LGA_775Processors that fit this processor socket, have the socket holes.
775 of them.
The LGA 775 processor socket, has the pins that go up into the socket holes of the Processor.
775 of them.
[The Socket 478 processor socket, that was before the Land Grid Array 775 processor socket, has the socket holes (478), and the processors that fit this processor socket, has the pins. {478 of them]
B) Supports processors with up to a 3.8GigaHertz frequency rate.
3.8GHz.
['Speed' is a slang term for Frequency Rate.
Giga = Approximately 1 Billion
Hertz stands for Cycles per Second.
3.8 Billion Cycles per Second.
Can also be stated as 3800 MegaHertz.
Mega = approximately 1 Million ]
C) Can support Intel Pentium 4 processors with HT.
Hyperthreading Technology.
D) Looking to the right of the Front-side bus (FSB) heading, you will see it states -
800MHz.
This means the Asus PTGD1-LA motherboard will support Pentium 4 processors with,
1) HT
2) UP TO a 3.8GHz frequency rate
3) Up to a FSB frequency rate of 800Megahertz.
4) Use an LGA 775 processor socket.
Now let's look at one example, of a chart of Pentium 4's with HT, that fits these specifications,
http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_.2890.C2.A0nm.29_2See the heading - Prescott (90nm)?
This means the processors in this chart, are based on the Prescott Core, and the 90nm architecture.
(nm stands for NanoMeter. Approximately 1 Billionth of a meter)
Looking at the headings in the chart, you will see Model Number, sSpec Number, Frequency, L2-cache, Front-Side Bus, Multiplier, Voltage, TDP, Socket, Release Date, Part Number/s, and Release Price.
At this point I would only concern myself with the,
Model Number, (If applicable),
sSpec Number,
Frequency,
FSB, (Front Side Bus),
Voltage,
Socket,
and Part Number(s)
1) Model Number:
The older Intel Pentium 4 HT processors did not have a Model Number.
Intel didn't start using a Model Number until later.
Model Number examples start with 517, 520, 520J, and so on.
Look for the sSpec Number, and the Part Number, for the older Pentium 4 HT's. They're printed on the top of the processor's case, and should be listed by the seller.
2) sSpec Number:
Intel brought this out.
Their way of marking a processor.
Another identifier for you to use.
3) Frequency:
The Maximum frequency rate, ('Speed'), that the Processor is supposed to be able to operate at.
4) L2-cache:
The small memory area for the Processor. The Processor accesses this small memory area first, because it operates at the same frequency rate as the Processor.
You can't change it, and 2MB of L2-cache, is the largest size for an Intel Pentium 4 with HT.
Just thought I would include this information.
(Ram Memory is next. Typically, Ram Memory operates at half of the FSB frequency rate. The Harddrive is next)
5) Front-Side Bus (FSB):
The frequency rate that the Processor transfers data (Information) to the Northbridge chip, and back from the Northbridge chip.
More on the Northbridge chip in a moment.
6) Voltage:
Pretty self-explanatory. The Voltage range the Processor will use.
You need the Voltage range of 1.25/1.4 Volts.
(1.25 Volts to 1.4 Volts)
Any Processor (That is Intel Pentium 4 HT, Socket LGA 775), that uses Voltage in this range will work.
7) Socket:
The type of processor socket that the Processor will fit in.
Has to be LGA 775.
8) Part Number(s)
Self-explanatory again.
The Part Number, that is stamped on top of the Processor's top case.
Part Number(s) is listed, because there may be more than one Processor in the Model Series, that fits the same specifications.
If there is no Model Number, refer to the sSpec Number, or Part Number.
The largest frequency rate (Speed) of Processor you can use, is a Pentium 4 HT that operates at 3.8GHz. (And fits in an LGA 775 processor socket)
Barring that a Pentium 4 at 3.8GHz cannot be found, you will know what Processors you Can use.
Scroll across the headings with your eyes, and start under the Frequency heading.
Find the frequency rate ('Speed') you wish to try.
Go across to the Front Side Bus heading. You should look for a processor listed that has an 800MHz listing.
Look at the Voltage.
All of the Intel Pentium 4 HT processors that fit in an LGA socket, use an 800MHz FSB, and are in THIS particular chart, fall within the same Voltage range.
Keep the Voltage range in your mind, as you look at the other charts below this one.
Socket.
You know you need a processor that fits in an LGA 775 socket.
Look at the chart below this Prescott Core (90nm) example.
Prescott 2M Core (90nm)
Use the above criteria above in this chart.
I wouldn't recommend any Pentium 4 HT's, in the Cedar Mill (65nm) chart.
It isn't that the architecture is smaller (65nm), but that the BIOS program,and version on your motherboard, may not be able to handle these processors listed.
I also do not see a BIOS update for one, and for two, if you make a mistake when performing a BIOS update, your motherboard becomes an expensive Frisbee, or doorstop.
You also do not want any of the processors listed under the Pentium 4 Extreme Edition heading.

(Mobile Processors are for laptops Laptops are M-O-B-I-L-E)
Northbridge chip.
1) The Northbridge chip, and the Southbridge chip make up the motherboard chipset.
(Does not apply to the new motherboards that support the Intel i3, i5, and i7 Core processors)
2) Chip and Chipset are slang terms for I.C.
Integrated Circuit.
http://en.wikipedia.org/wiki/Integrated_circuitThe Northbridge chip handles the faster processes of the computer.
Processor, Ram Memory, and High speed graphics.
(AGP or PCI Express. Not a graphics card in a PCI slot, nor Integrated Graphics on the motherboard. These are slower processes of the computer)
http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg(CPU = Processor
Memory Slots = Ram Memory slots)
Looking at the diagram, you can see the slower processes handled by the Southbridge chip.
Looking back at the Motherboard Specifications, look across from the Chipset heading.
Northbridge: i915P graphics and memory controller hub
(MCH)
Southbridge: ICH6 Intel I/O Controller Hub 6
Uses an Intel 915P Northbridge chip, and an Intel ICH6 Southbridge chip.
