thx u
im quite happy with the perform of the 730 can overclock more then a ghz that what im aiming for =)

Very nice overclock. :)

/me shakes fist at his motherboard + error. :(

how u get the xp90 to fit in ur p4p800se?

Bend the brackets back so they will tighten the cooler again.
Then bend the 'feet' that hook into the retention module back so it will fit again.

http://members.home.nl/djthesp/xp90bend.jpg

Just keep in mind that everytime you think it fits ok and you want to turn on your computer you make sure it is
thoroughly connected with the processor surface.

Hey guys, I was wondering if anyone knows how the C0 400FSB Pentium M's overclock? I'm looking at a SL89T C0 "725A". But do these CPU's have the same problem the Celeron M C0's have? (~180FSB).

Yeah thats the way, however me being changing cpu's now and then have broken one of my retention clips due to metal fatigue... were can I get new retention clips?
Alternatively some other solution...

Try these, perhaps. They're for another model of Thermalright HS, but I believe they are the same:

i try to do it, but i found i can't fit XP-90C on the CPU COOLER module, would you explain it clearly and show me more pictures.

thanks a lot.:toast:

i got two PM740, one is normal, another is better. pls take a look at pic below:

Here's another hand drawing:

See how the cooler brackets are different?

All you have to do is bend them with some tools.

The easiest way to do this is to just put the cooler on the processor and try to point out where you want to bend it to make it fit with your tools.

Be sure to bend it 2-4 mm sooner on the cooler bracket then where you initially wanted to bend it. (This will ensure the bracket will fit tightly on the processor).

Still the risk is all yours, but its not that hard really.

PI time is around 31s for 1M (my P4 OC'ed to produced 34s). It has been very stable at this speed. I might get more but I wanted greater stablilty.

Ok, I have my 730 installed and it works fine at the stock speed. I want to overclock it but I have two problems with the first page in this thread...

1) the link to the vcore wire mod is dead

2) the clockgen link is dead, and the latest version at http://www.cpuid.com/clockgen.php doesn't allow you to save and load settings on startup.

Can anyone help me out with a copy of the wire mod pic and/or a copy of the right version of clockgen?

Just for the hell of it, I lowered the memory speed to 233 and tried to just bump the FSB speed up just using clockgen *without* doing the vcore mod but it was *really* unstable.

Once I get the vcore mod done and get the clockgen thing worked out, I'm planning on doing some sort of aftermarket cooler setup but I have a very cramped case (the Superflower case in this Tom's Hardware review... http://www.tomshardware.com/2003/12/...review_part_1/ ). I'm thinking leaning toward either the Zalman CNPS7000B-Cu or the Zalman CNPS6500B-Cu as it seems people have had good luck with these coolers.

Can anyone provide pros or cons to either cooler, especially in a cramped case?

Thank you very much. i understand what you said. the XP90 is not hook the rentention module, it is withstand inside the module. am i right? i will try to do it again.:D

i mod CT479, and it is work on my P4C800ED. the cooler bracket is very tight, it is difficult to bend. i will upload pic later.

thanks all.

I also have a weird issue completely unrelated to the board. Out of 3 boards, and several processors, I always have a default voltage of 1.55v. I pinmodded my adapter last year, and removed it ages ago...yet the results seem to have "stuck"...there is no way it seems for me to lower the voltage. I even tried forcing a pin mod for 1.356v to no avail. And even on this P4P800VM which doesn't even have vcore options, it's still way up there at 1.55v. :confused:

---

You can change multi downwards on P4P800-VM if you are using BIOS version 1017. The function has been disabled in newer releases of BIOS?? For beeing a SFF-board it performs great!

Rather than bend the brackets on the cooler, why not just raise the P4 heatsink retention bracket with nylon washers?...

Hold on, this doesn't make any sense to me. I thought it was a little weird to bend the clips *UP* but I didn't think about it beyond that. Now I have to ask: Shouldn't you bend the clips *downward* to reach the retention bracket that is effectively farther away with when the heatsink is mounted on the CT-479?
Thus:
Extra height of the CT-479 (1/4" for argument's sake) = bending the clip down by an equivalent 1/4" to reach the extra distance to the retention bracket.

And if you are talking about hooking the clips somewhere else, like on the CT-479 itself, where is there a secure and sturdy enough spot to do it? Wouldn't it damage the circuit board of the adapter?

Along the same line of thought, raising the clips with washers would be wrong too, wouldn't it? How about mounting the clips using the same screws, but underneath the heatsink instead?

Somebody correct my error in thinking, here, if I am wrong...

Yes this is another possibility.

But it will require the right screws and bolts for the retention module as well.

NOTE:

I am _not_ saying the hooks of the cooler should be placed inside the retention module nor did i mean to imply you have to put the hooks around the CT479.

Bending the hooks backwards is necessery to make them shorten in length because the processor will indeed be risen by the CT479.
After bending them backwards you should take the tip of the iron hook and bend that back to make it fit back into the retention module again so it will fit like it normally should.

For anyone who is looking for the older ICS952607 specific version of ClockGen (aka CG-ICS952607.zip) that supported "ghost mode" and can be run at windows startup, I've collected all the old versions I could find and put them on my web site. Enjoy...

http://krick.3feetunder.com/clockgen/

Nice.

Too bad i cant seem to stop my Onboard sound chip to get affected by overclocks.

Even though my bus speed is locked in the BIOS.

(My northwood didnt have this problem at all on the same motherboard).

i solved the problem in my own way about how to install XP90 on CT479. you should mod CT479 power supply module. i will send pics later.

I'm currently running a (non-overclocked) Dothan 730 in my P4P800-VM. I've tracked down the right version of clockgen but I still need the instructions for the easy vcore u-wire mod (1.55vcore). The link on the first post is dead. Does anyone have a copy of the pic or know where to find instructions on how to do it?

I also recently got ahold of a P4P800 Deluxe. Does anyone know if the latest beta BIOS 1021.006 has Dothan support? The first post of this thread only mentions beta bios 1021.003.

I'm still not sure which board I'm going to use the Dothan on. Any thoughts?

I understand where you're going with this. The idea is to have the heatsink apply the same amount of pressure to the core of the Dothan/CT-479 combo as it did to the P4 mounted in the original socket. Since the Dothan?CT-479 raises the height of the heatsink, it means the clips would need to be pushed further to hook onto the motherboard bracket. Pushing the clips further means the heatsink would place more pressure on the core of the CPU. We want to alleviate this and the only way to do so is to permanently bend the heatsink mounting clips downward by a distance equal to the extra height of the Dothan/CT-479 combo. We want to negate the extra height to keep the mounting pressure the same. Bending the clips back (upward as is depicted in your drawing) will do the opposite.

Please understand that I'm not arguing with you just to be contrary. I'm concerned that someone who performs your suggested modification will run the risk of their heatsink placing too much pressure on their shiny new Dothan and crush its core. I think the idea of bending the clips to mount an XP-90 is a great idea and will work as long as you bend them in the right direction: downward toward the motherboard.

-Erik.

i got the say the dothan 730 is one of the best oc chip i got mine to 2.7 with 225 x 12 with 1:1 ratio just cant the 2-2-2-5 timing vcore at 1.6v

most stable with 1.6v would be 217*12 at 2.6 with 730 dothan

Hello

My p4p800SE has been died :( I have a p4c800 deluxe and I put bios beta 1021.005 so that it can work with they dothan and it works well but by defect multiplier 6 is put and there is no way to change it :mad: to somebody but happens this to him, or knows as I can solve it?

What kind of cooling are you using?

I was looking at the Zalman 7000 and the Zalman 6500.

I think the heatsink retention frame is too close to the edge of the board for me to use the 7000 as it will probably hit my power supply.

ZALMAN 7000 works fine, without mod.

the only thing u r going to do is to reverse the clip and find two long screws.

I mounted a zalman 7000Cu on it

I have a P4P800 SE on it's way to me and as I'm sure you know, the price of Northwoods is crazy. I just recently realized I might try a Dothan in this mobo. The hard part now is finding a CPU to use. What's up with this ebay link listing the Dothan as 478? Is that correct? Does that mean I wouldn't need the CT-479 adapter?

http://cgi.ebay.com/Intel-Pentium-M-...QQcmdZViewItem

You definitely do need the ct-479 adaptor, I have recently replaced a
p4 2.6c in my p4p800 deluxe (bios flashed to p4p800se 1012.001 beta)
with a dothan 715 @ 2.42ghz. I got my adaptor here in Australia for
$59 only 4 weeks ago but they now don't have it listed anymore.
I think Intel still views it as a 478chip even though it is not compatible
with that socket. Just make sure if You get one off ebay that the
Piccy matches up with the description, as usual buyer beware.
Mine runs at 162fsb and ram at about 404mhz on 333 ratio.
I recently borrowed a 730 533fsb unit , and even though you can
get over 200fsb no problems It doesn't make any difference to
ram bandwidth, which I found surprising, although the 533fsb
units will give you about 200mhz extra.
By the way it kicks the old 2.6c's ass when it comes to games.

Has anyone got a piccy of the simple 1.55v u-wire mod? [Link dead on the first page, unfortunately]

Just got my 750 through the post this morning, £50 off ebay, so I'll find out what my P4P800-X makes of it tonight if I get time :D

I'd get a Pentium M 730 and a CT-479 adapter.

eWiz.com has pretty cheap prices and I've never had a problem.

If you use Froogle to find the items, click through, and add them to your cart, you get a special discounted froogle price. You can get both for $162. The items should show up in your card prefixed by [FR]. See attached picture.

Here's the Froogle links...
CPU $120: http://froogle.google.com/froogle?q=...m%20730%20ewiz

Superb - thanks a lot krick, appreciate it :D

Thanks for the help krick but I'm being turned off to the idea now. I just want to drop in a CPU and go without having to modify or mess around with heatsinks.

Who says you need to modify heatsinks?

The CT-479 comes with it's own special heatsink. No modifications necessary.

I've got a Pentium M 730 overclocked to 2.7GHz using the stock heatsink in my P4P800 Deluxe motherboard.

The only reason I'm asking questions about other heatsinks is because I want to try to get to 2.8GHz or higher.

Well I did a pin mod of my own earlier, but not the good kind. One of the corner pins of my CT-479 snapped off in the socket, rendering both board & adapter useless until I can fish out that pin. The odds were stacked against me with an unsupported board, unless I get that pin out I can't even try a dodgy flash from a different model, in an attempt to get the chip to post. Ah well...

When I overclock to 2.7GHz and run prime95 torture test, it hovers around 50 degrees celsius I'm pretty sure that's still within the thermal envelope but I'm hoping a better cooler will bring that down and allow me to run a slower quieter fan.

It seems that on my P4P800 Deluxe, I'm hitting a wall with the memory (225fsb). I'm currently using 2x512 Crucial Ballistix PC3200 and I managed to get it stable at 1:1 running CL2.5 but only if I set all the other timings to their slowest.

I've got 2x1024 Mushkin XP4000 PC4000 at my disposal and I'm going to give them a try and see if I can do any better.

The "thermal envelope" for the P-M's is very high (>70c) since it was designed as a laptop CPU where temps tend to be high

Ok. I'm running prime95 torture test (blend) at 2.7GHz (1.55v) with my new Zalman CNPS7000B-AlCu. It's hovering around 43 degrees Celsius.

I can't seem to get it to boot past 225 FSB. I'm not sure at this point if it's the processor, the motherboard, or the memory, but relaxing the memory timings with two different sets of memory modules didn't make any difference.

I also swapped in a different more powerful high-quality power supply, just in case.

I've got the Vcore in the BIOS cranked up to the maximum. The setting says 1.60v but according to SpeedFan, the Vcore is 1.55-1.57.

I'm wondering if more voltage will help. Can you do the easy vcore wire mod in addition to the BIOS adjustment? If so, how do you know what the actual voltage is?

Well after googling a bit, I think I'm running into the infamous p4p800 "voltage droop" problem.

Luckily, there's a vcore "droop mod" documented here...

You should be able to get more FSB if you boot at 200 or 201 -- then raise the FSB more in windows (250+ depending on your RAM) using clockgen.

I can boot into windows at 225, but if I then try to bump the FSB up with clockgen, it crashes.

no not at this point cause in q4-06 e4300 c2d's are out have 8x multi and more then likly can go from 800fsb to 1066 no problem. i read that intel plans to price it at the 150 mark. would be the best bang for buck when released. i cant suggest to anyone atm a dothan setup unless you got a really good deal for all of it togher. i sold the mobo/ram/ct-479/dothan 730 @2.4ghz for $125, was a great gaming machine.

nice price considering i paid 150 for a pm730 last june/july.

hey guys, can you guys post some pictures on how you mount the xp-120? and has anyone tried to mount the ultra-120?

@CRXican

unless you could find the rare p4gd1 or a ct-479 ready mobo on hand already, it's not worth putting your money on brand new dothan setup, plus high end agp cards are way too expencive these days

You can get one of these Thermalright metal retention brackets...

...then use nylon washers and longer screws to raise it up to the right level so you can use any P4 heatsink without modification.

i have a overclocked p4p800-e deluxe with ct-479 and a dothan 730. cpu was overclocked to 2.7Ghz stable. i havent turned the machine on in the past 2-3 weeks, yesterday when i tried, the machine starts. goes to the post screen and shuts down. keep repeating this. sometimes it shuts down right away when it gets to post screen. sometimes it shuts at scanning ide drives.
I tried the cmos clear, i also see the cpu and the memory are detected correctly on the post screen.
anybody have seen this issue before?

here is the system spec
p4p800-e deluxe with ct-479 + dothan 730 w/zalman 7000-cu
2x512 ocz platinum tccd
6800ultra agp
seagate pata drive and generic cd-rw.
antec 550W True power PSU

I am running a 730 P-M and the stock CT-479 cooler, 1.424V core a 227fsb x 11=2.5ghz on a P4C800-E, with corsair value ram pc3200 SPD cas2.5,3,3,8 @ 1:1 so ram is at 227 at stock timings, 2.85V, also running a 9800pro and true 550watt PSU.

Idel cpu temps is 37C and full load is 50C

is this the best deal for a good cooler??? or can somebody post a link to a better deal in the USA please, thanks.

I have the Zalman CNPS7000B-ALCU.

I have two motherboards that I've tried my CPU in. In my P4C800, I'm seeing idle temps at 37C *with* my Zalman. Under full load, it hits 50C. I really don't understand what's going on. It doesn't appear to be overvolting it but the heat output would suggest that must be the case. It also won't overclock as high. I can only boot at 2.6GHz and it's far from stable.

However in my P4P800, it idles around 30C and hits about 45C under full load when overclocked to 2.7GHz with the voltage cranked up to 1.6V. At the stock speed (1.6GHz) and voltage it idles at 28C and hits 35C under full load.

$25.95 is the best price I've found for the Zalman CNPS7000B-ALCU.

It's dead simple to mount too:

1) purchase longer 6-32 x 1 inch machine screws Lowes/Home Depot
2) remove the fan on the zalman cooler
3) flip over the "floating bracket" that was under the fan
4) re-attach the fan
5) install the aluminum bars upside down into the P4 retention bracket
6) screw down the heatsink with machine screws purchased in step 1 (make sure that the fan power wire is on the same side as the power cable on the adapter.

Just a tip though, before you try to install the new cooler, take the stock ASUS cooler and carefully peel the felt spacer/shim thingy off the bottom. Now carefully stick it on your CPU instead. That will help protect the core from being crushed when you install the new (much heavier) cooler.

Also, it's a little tricky to work around the wires on the adapter power plug. Many people pry off the white plastic base and bend the pins over. If you're careful, it's not really necessary. You can install it by just bending the power wires out of the way and being very careful to not pinch them when tightening down the heatsink.

How do you 'crank' up your voltage?

Is there an easier way then soldering stuff onto the CT479 PCB?

On most motherboards, you can adjust the CPU VCORE voltage in the BIOS. My Pentium M seems to do 2.6GHz at about 1.45 volts. If I bump it to 1.55 volts, I can get it about 99% stable at 2.7GHz. If I bump it to 1.6v, I can boot into windows at 2.8GHz but it's nowhere near stable.

If you don't have BIOS options, you can do the "easy wire mod" to bump it up to 1.5 volts. Check a few posts back, I posted a picture of it.

Also, and I'm not positive about this, but I believe that when the jumpers on the CT-479 are set to "400", it sends more voltage to the CPU than when you have them set at "533". However, I'm not sure how much and if it would even make a difference.

Is here anybody, who tested Celeron M380 max oc ?
I have mine m370 running at 2,55 Ghz. Max oc is near 2,6 ghz.
I think the fsb cannt be reached, because is 100 fsb. Anything over 170 fsb isnt 100 stable :-(

I also just got here one Celeron M 360J for 25$/20€ :cool:
And maxfsb is also around that 170.
Imo most of all these celerys do about fsb164-170 without mod but some also ~185
Something to read about M380 OC maybe here-> http://www.xtremesystems.org/forums/...ad.php?t=64608

I secured another Pentium M 730 off of ebay for $45 and another CT-479 from eWiz for $42 and went to work on my ASUS P4P800-VM.

Since the P4P800-VM doesn't offer vcore adjustment or FSB adjustment in the BIOS, I did the easy u-wire mod on the adapter to bump the core voltage to 1.55V.

I put the CT-479 jumpers on the 533 setting.

In the BIOS, I set the memory speed to 266 (to get the 1:1 memory divider) and the memory timings to auto by SPD. If I tried to manually set the memory timings, it would immediately crash in windows so leaving it at auto was the only option.

After booting into windows I have...
CPU - 1600MHz (133x12)
MEM - 133MHz (1:1)

Then it was a simple matter of firing up Clockgen and cranking the FSB as far as I could go. With this CPU, 4 sticks of memory, and the stock ASUS cooler, I was able to get the FSB up to 196.1 and have it still be stable during a Prime95 (blend) torture test.

I can get the FSB a few clicks higher but not stable. If I go to 198 it immediately crashes windows.

So my results so far are...

CPU - 2352MHz (196.1x12)
MEM - 196.1MHz (1:1)
Prime95 blend torture test full load: 65C

I tried this CPU in my other system that happily runs at 2760MHz (230x12) and this CPU doesn't fare nearly as well so it's likely that I've reached the limit for this CPU.

I'm pretty happy with the results, but I can probably do better so here's some things I might try to see if they make any difference...

better heatsink / better memory / less sticks of memory

I probably won't do the CT-479 mod on this one because that was a LOT of work and I don't think it really made all that much difference.
