I have probably asked this question sometime here in the last few days

it will be burried amongst the threads now so sorry if i am duplicating a
question (im sure that happens alot on usenet)

But can mobile Athlon XP's with an unlocked multiplier be used on a standard
socket A board? and with a standard AMD stock heatsink?

plus would you reccomend OC'in it with a standard AMD heatsink i got with my
locked 2600+ XP

I have a few case fans and my case is massive, airflow is excellent

and my PSU has 2 fans that keeps things cool (when fan is on full power)

Thanks,

Chris.

You need the ability to adjust the multiplier and FSB in increments, either
through the BIOS or on-the-fly in Windows. If you can't do either, then
your XP-M may only run at a very low default multiplier. What motherboard
and RAM do you have?

You'll be OK up to a certain level, but you'll get better results with
something more substantial. Don't expect to get 2.5Ghz with a standard AMD
heatsink.

What is the standard socket A board (via 266, via 333, via 400, nvidia
nforce 2, ect.)?
I would not recommend using a standard AMD stock heat sink for overclocking
unless you don't plan on raising the cpu core voltage.
If you use a standard AMD heat sink, overclock the processor, and increase
the core voltage you will have to watch the temperatures closely.
The AMD heat sink will not dissipate enough heat to keep the cpu stable in
an over voltage environment. Most AMD heat sink will provide about 0.5 to
0.55 C/W. At 80 watts that's a temperature differential of 44°C
(0.55x80=44) over the case temperature. At 90 watts that's a temperature
differential of 49.5°C over the case temperature. Assuming a well
ventilated case ambient temperature of 26°CO and a case temperature of 30­°C
to 32°C that adds up to 76°C (32+44=76) on the cpu at 80 watts. At 90 watts
you will have a cpu temperature of 81.5°C. The max temperature for the cpu
is about 90°C. At 45 watts the cpu temperature is 56.75°C. You really need
a heat sink that is rated at 0.4 C/W or less to keep the cpu stable when
overclocking and the better heat sinks are rated around 0.3 C/W. These are
not motherboard temperature cpu sensor numbers. These are core temperature
numbers. The mother board cpu sensors are generally 6°C to 10°C less due to
calibration and placement of the sensor. Simple calculation for power in
watts, power = voltage x current.

I am sure that you have seen this before.

The NF7 will run a mobile fine. The only minor issue is that the stock
BIOS will not recognise it and will show 'Unknown CPU type' at POST,
you will also have to manually configure the multiplier and FSB the
first time you start up.

also note that nf7 with amd mobile doens't like it too much if you change
multi, fsb, and cpu core voltage at the same time (no boot, needing cmos
clear)
it works ok if you change cpu voltage first, then change multi/fsb

With PC2700 you can only guarantee 166Mhz times your multiplier, which
limits your overclock considerably. Anything over 166Mhz is a bonus, but
you'll need at least PC3200, or preferably PC3500 or PC3700 to reach its
full potential.

Agree about the PC3200 comment.

PC3500 or PC3700 are usually more expensive not worth it. If you get good
3200, its probably the same chips anyway.

no worries i just recently updated with flashmenu got bios 26, believe i was
on 25 when the board arrived.

and as for the FSB etc,

would you reccomend starting at 11x166?

with a vcore of about 1.6 ish

The PC3200 needs to be cas 2.5 or cas 2.0 and the cas 2.0 ram will allow you
a little head room.
The PC2700 that you have maybe able to run at 400Mhz depending upon the
original cas latency. If the original cas latency at 333Mhz was 3.0 it is
not likely that the ram will run at 400Mhz, but if the cas is 2.5 at 333Mhz
you could raise it 3.0 and increase the other three latencies to something
like 3 3 11 or 4 4 11. Also you may need to increase the ram voltage to
2.8v.

The Merlin modified bios (D25_Cpc_On_rev.3D_by_-=Merlin=-.zip) will
recognize the mobile amd and helps with some stability issues at higher
clock speeds. Another good one is the tictac bios
(d24_3d_4227_d10bpl.bin.zip). Both of these modified bios's will give you
the 10.5 multiplier if you need it.

1. Start at 10x166 them increase the FSB until you reach the highest FSB the
ram will run at, you may want to set the ram at cas 3, (4 4 11) and a
voltage of 2.7 to 2.8. This will let you know how far the DDR2700 ram will
go.
2. then back down the FSB back to 166 and increase the multiplier to 11,
slowly increase the FSB until you reach the limit of the ram or cpu which
ever comes first.
3. If you reach the limit of the ram before the processor then repeat step 2
with 11.5. If you reach the limit for the cpu the back down the multiplier
to 10.5.
4. Leave the voltage at the lowest possible setting to start 1.525v or 1.55v
and then increase it in small steps to maintain stability during both steps
1 & 2. Remember that the higher the cpu voltage the more heat that cpu will
generate and the more power it will draw. Watch your temps and 12+ voltage
rails.

You need to know how far you can push the ram before you start to push the
processor. The ram DDR2700 will be the limiting factor. No two system will
respond the same and you will have to find the best setting for your ram,
cpu, and video.

I hope this helps.

Never said it couldn't be done it all depends on the ambient temperatures
and how well the cpu you have is put together.
The C/W values for heat sink are based on the physical laws of thermal
dynamics. What your cpu will do in reference to the thermal properties of
the cpu will vary from cpu to cpu and from batch to batch. Sounds like your
cpu will run at lower voltages and requires less power to do it. Be willing
to bet that not all Mobil AMD will OC that well on a boxed AMD aluminum heat
sink and fan combination. All AMD Mobil's are OEM and do not come with a
fan. I assume that you are using a solid aluminum stock AMD boxed heat sink
and fan and your case temp's are below 30°C. AMD does box some of it's
cpu's with copper core heat sinks, which one do you have? It makes a
difference. I believe the copper core heat sinks have a value of about 0.42
C/W to 0.45 C/W. If you add 8°C to the thermal cpu reading from the bios
and run the burn in wizard on the Sisoftware Sandra software v2004.SP2b for
20 iterations you should be able to figure it out.
That should tell you just how fine it really is. The destruction from heat
does not always show up immediately it could take months for the you to see
the damage. It first appears as memory errors as the cpu writes data out of
the L1 and L2 cache from the cpu to the ram. I know from experience. Some
times you can salvage the cpu and some time you can't.

If it were me I'd set it up at 13 x 166 @ 1.65 V to start with ....
You should be able to go higher on all settings but around 2200MHz
clock speed and desktop default vooltage is a good starting point.

What are you multiplier and fsb settings ? I just got my abit nf7-s and
