If you can find a couple of bolts with the correct thread beween 25 and 30mm long then the job should be very easy.

When mounting the heatsink, make sure the gap between each of the two aluminium brackets and the heat sink is equal, or the processor core wont be covered entirely by the copper in the heatsink. This isnt as easy as it sounds, since the power supply cables and speed setting jumpers tend to push the heatsink to one side, leading to a ofsett mounting of the heatsink and the core being coverd partly by aluminium.

The center center clip/bracket has to be fipped upside down, I removed the fan assembly to make this easier. The problem then, is that the center clip/bracket isn't designed to be used upside down. In correct orrientation the load is placed through the rounded \/ bottom edge of the _!\/!_ clip, so the relative tightness of the two fastening bolts is not too important. However once the clip is upside down the load of the bolts is taken in two places (each side of the heat sink instead of one place in the center of the heatsink.)

I counted carefully the number of turns on each bolt while tightening, to make sure they were both turned the same number of times. Once the heatsink began to grip the processor core, I made small twisting movements on the heatsink to see which side of the heatsink was gripping the core most. Then I made small adjustments on the bolts until the heatsink seemed to rotate about it's centre when twisting. Then I finished tightening with the same number of turns on each bolt.

Hope this helps.

guys you got to remember to put the white foam that is from the original fan because it helps to not crack the cpu

i have test my PM780es on P4P800se and CT modded

with bios 1008 1010 and 1011 , it s impossible for me to bench over 220 mhz ram 5-2-2-2 :/

i have vcore vdimm vdroop and vchip mod but no way :/

anyone has an idea ?

Hi guys

I just bought a Dothan 750 and Asus P4gpl-x mobo second hand. When it boots, it says cpu overheating. If you go into the bios itself it reads random temps like 124c then -124c then it shuts down.

The heatsink isn't warm yet it is touching (I cleaned off the paste on the heatsin k to make sure).

The previous user had it running ok.

I'm guessing after clearing the bios I need to re-do some settings to get it to work correctly first?

Cheers for any help :)

124c! OH! You should check your mounting system. Stock HS? The hs should be at least warm if CPU is 124c.

I put in a 2.4c which works ok, so I think it's the heatsink itself (?). I've ordered a Zalman flower heatsink which should do the trick ;)

Hi everyone,
I currently have a p-m 750@2.8GHz on 7700AlCu. I am kinda worried since temperatures are going too high (close to 60C). Do you think that switching to the SonicTower will be an improvement ? Any testimonials of users with previous experience, please?

what multiplier are you using?

i had similiar issues before my chip went south. but i think it is a common
issue with the 780es' chip (not the going south ;) bit).

i had the 780es running on a p4p800-se, still have the board though, and
it was / is running the 1009.003 bios iirc. to me that was the best bios for
the p4p800-se.

anyway. i could get the fsb up to 290, with asynchronous ram at 10x only.
one time i also had another 780es that would do a little less fsb-wise
using the same voltage / multiplier settings, but ended up somewhere
close by in terms of absolute speed. but both chips behaved very much
the same in this multiplier vs. fsb issue.
with the multiplier at 12x i could get a max of 243 mhz, and the higher i
would go with the multi, the lower the possible fsb would get. - and i had
not even maxed that chip yet.. was running ~1.5v, so plenty to go...
all those tests were done with the ram-divider set to 5:4, so at fsb 291
the mem was running 233-5-2-2-2, 2x512mb khx3200 (bh5) btw.
with my 760 running on the same board, i had my fsb up to 305, ram at
244-5-2-2-2 and went through am3 with it (the maximum was 313, 5:4,
250-5-2-2-2) - so the board wasn't and isn't the culprit.

also going to lower multipliers, like 9x, didn't help one bit. actually with
the 780es' it seemed to get worse fsb-wise. 10x was where i could
squeeze the most out of them. the 760 on the other hand loved the 9x,
as i could top out the fsb there... strange little fellas. maybe a regular
780 (retail) would do the trick as some suggested?

i test under casacde so i boot bios a 200 x 17

on windows all the coefs make me errors :/

do you have a link for the 1009 beta bios ?


the problem is that i want to bench 1:1 around 3700 :D

i'm sure i have all the 1009 bios files around (001, 002, 003, .. ). i'll check
once i get back from work and am awake again, but i'm positive i have
them. i'll pm you when i find it tomorrow afternoon - can't check from
here as my server is not accessible from the outside world :D..

3700 1:1 whoa 284x13 or 264x14... makes me wish i had a cascade at my
disposal.. :)

Is this also generally considered a good bios for the p4c800, or is it better to stick with the 1024.001?

a P4 2.4c must boot with all the bios on P4P800se ?
have found the pb :p

plain p4c or p4c800e-dlx?
anyway, i think there was another bios named 10001_023 (p4c e-dlx),
but i wouldn't know if that was any better than the 1021 or the one
i mentioned above. i never got hold of a p4c800.
also wasn't there a "special" p4c bios customized by tony? i think i do
remember something at the very back of my head. hm


and skirms... is that a default fsb100 part or 133. i don't know much
about the p4's, completely bypassed them, but maybe it's the same
issue as with the p4gd1 that would not like to be flashed / run with
a stock 100 cpu? (just guessing)

What is the best bios for p4p800se?

u'l probably ahve bad contact with the core,are arent using thermal paste

Voltage is close to 1.6V. How better is the Sonic Tower from the CNPS, will there be any significant improvement if I replace it ?

Just in the middle of fitting the huge Zalman flower copper heatsink to my Dothan 750.

It's a bit of a nightmare to fit.. similar fitting as the 7000 range but it sits a little too high atm so isn't getting very good contact - idles ~45c / load 70c+ lol. I'm having to force small pieces of foam between the bracket where it pushes onto the p4 heatsink adapter, so it pushes the new heatsink down a bit.

I'll post some pics when done. Currently running at ~2.3ghz

70C in full load at 2.3GHz ? I am at 63-65 at 2.8GHz. You really have a problem there.

is there anyway to mount a swiftech apogee water block on he ct-479? i mean even with zip ties or something... im highly considering changing out my system for the p4p800-se but only if i can mount my water system on it.

question: has anybody managed to mount Thermaltake Polo 735 on ct-479? and was/is it difficult?

i've managed to mount zalman's 9500 led cooler.

Hi,

anyone an idea whre to buy this adapter ? Cant find it in germany and i like to have it till Saturday .

regards

I recently got a good heat sink for S478 from a dumped Shuttle XPC (poor XPC got its ICH5 fried because of the USB hot plug sudden death syndrone)

Tried to install that heatsink into my CT-479 system and the result was quite successfully.

This is basically what I did

I bent all standing up pins on the CT-479 so that they don't block the heat pipe (The CPU on the CT-479 was a C4M 1.6, just use it as a place holder in case if the test goes wrong I won't crack my 740's silicon :) )

http://img10.picsplace.to/5/HeatPipe_Mod1.jpg
http://img10.picsplace.to/5/HeatPipe_Mod2.jpg

Moreover, use Glue Gun to make 6 pads on the CPU's organic packaging. I found this method is quiet handy, the glue is very hard when formed, hence can protect CPU silicon from being chipped, especially the 4 weak corners.
http://img10.picsplace.to/5/HeatPipe_Mod3.jpg


Then here comes the big guy:
http://img10.picsplace.to/5/HeatPipe_Mod4.jpg

Another important lucky thing that I found was the S478 steel back plate. I fixed that thing on top of the cooler's base, so the CT-479's two clips can be used directly.
http://img10.picsplace.to/5/HeatPipe_Mod5.jpg

This, is what it looks like when installed. The heatsink is so big that it nearly step out of the case! :wow:
http://img10.picsplace.to/5/HeatPipe_Mod6.jpg

Another point of view
http://img10.picsplace.to/5/HeatPipe_Mod7.jpg

Completely silent LOL, (no unless I find someway to shut the video card up)

This mod is done on a P4GD1 motherboard.

i got ct-479, M740 and works at 13x200=2600@1.45V
super pi is 34s. it's extremely small, so is it cos of 2x256MB memory not operating in DC and workin at 400MHz or whay? i have the P4C800-E DLX with 1023 BIOS

My got 29s in Spi, running 512x4 @ 200MHz, 2-3-3-7

check your timings

yeah i'm aware of that i wrote i have s h i tty memory:( 2.5-3-3-8 what's the difference beetween 512x4 and a OCZ platinum kit 2x1GB 2-2-2-5@400MHz?

2-2-2-5 would definitely run faster

Its possible, but theres so much weight that you need to put a IHS on it otherwise it will lose contact with just brackets.

I took the brackets off the CT-479 and bent them to slide them on the ninja, then just bent them back to normal, and it works perfect, difficult to get on but its obviously much better than the stock heatsink.

I managed to take a picture of it after it was all set up, you can only see the C through the fan on the adapter.

Its a 740 dothan at 2.82ghz with a bus speed of 940 mhz. Max temp about 48C, voltage 1.504.

Thats also using some thermaltake white goo, since i lost my AS5

Question for CT-479 experts: Is it possible for the Vcca mod to kill ram? Doesn't seem like one would affect the other, however, I lost one stick and then a second a day later. Happened while attempting to set a high FSB through clockgen. Never had a problem with this memory until the day I did the mod. other info: p4p800se mobo and TCCD ram... Mem voltage never set out side of 2.6 - 2.8 range.

I bet mobo took your ram......Happens all the time I believe with the P4GD1 and P4C800.....I've lost three of my rams on these mobos too......Rams that where working 3 years onto ABIT IC7 mobos......:(

hipro,
are those rams really dead or do you think it's more of the spd-chip that
got bugged? a thing that could be fixed using the tutorial waus posted a
while ago.

At least on my rams, SPD was dead.......

I have a Asus P4P800-E Deluxe with BIOS v.1008

Will a CT-479 work with this version or do i need a newer BIOS?

Its says on the ASUS website v1007 "Added support for CT-479".

Is that still included with version 1008?

Da_maniaC
Yes it is work with bios ver 1008.

OK, thanks. :)

I also have 1 stick with dead SPD and impossible to restore using that Typhoon SPD writer.
That stick works on VIA chipsets though but no other chipsets :D

I have a P4P800-VM.

I'm thinking about picking up a CT-479 and a Pentium M and doing a little overclocking.

Based on the first post of this thread, I'm going to look at the 730 and 750 CPU models.

And I know I'm going to have to resort to using clockgen since the P4P800-VM doesn't offer any overclocking options.

Has anyone been successful overclocking the Pentium M on this motherboard?

I've searched the forums and I can't find anyone who has.

If it's possible, what should I expect in terms of results and what should I look out for?

Krick, I should be able to let you in a bit. I swapped out a P4C800-E Deluxe for a P4P800VM because I need an SFF rig to put my Dothan 730 in.

So far, I have not gotten the multiplier support to work on this board...so it appears we're stuck at stock multi out of BIOS at least.


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:

IIIRC, I think that if you search this thread, there have been problems getting this board to FSB's above 170. I have one and haven't tried, although mine does provide options to change the multiplier in the BIOS.

I have a 730 on a P4P800-VM.

First thimg I did was use the pin mod to up the VCore to 1.55v (see Tricks thread)

I see the multi to 12 in the bios and boot at 133. During the STARTUP, I run clockgen and get the FSB to 200mHz. This gives me a 2.4g processor for my HTPC. I am using stock cooling, running around 57C at load in an A/V cabinet.

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.

Where in the BIOS did you change you multiplier?

For a P4P800-E, you need to flash to a P4P800SE BIOS. If you search this thread, you can find instructions for doing it. Most importantly you need an older version of AFUDOS or you'll kill your board.

And is there any place where i can still get the modded 1021 BIOS (That is in the startpost)?

Also, about the bootblock.
Will the correct version of AFUDOS just leave it alone or do i have to use extra parameters?

Thank you. :)

If you go here:

you'll find instructions on how to do the flash. The AFUDOS link there is not working, though. If you PM your email addy, I'll be glad to send you what I'm quite sure is the version that worked for me.

hey
on my 730 dothan i cant get pass 225 fsb * 12 multi

http://uploads.vancouverxchange.com/.../sadsadsad.JPG

i love pentium M power

One question for P4GD1/P4GPL-X users: at which PCI-E frequency does the SATA Controler fail? Some people say 110 PCI-E, others say 120 PCI-E.

Hi guys - just a very quick question.

My stock cooler (CT-479 on a 770) is dead - need to get a replacement.

Is Zalman 7000CU the best/easiest choice, if I dont want to do moddings on the cooler?

I would love a fast reply, since I have to get my computer up and running asap!

Cheers!

7000alcu is actually a little lighter and cheaper, so that's your best bet. it mounts very easily

Will it cool just as good as the cu model? (and thanks for the fast reply, by the way :) )

The pentium m has so little heat dissipation that you dont need a terribly efficient air cooler to get maximum performance, so yeah alcu is good enough.

My zalman fatal1ty fs-c77 has no difference in temperature when i hold my fan or not.

@ 2slick4u

Very nice overclock. :)

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

yes, it will cool it just fine.

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

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:

http://members.home.nl/djthesp/thermalrightmod1.jpg

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.

Thx... I'll promptly order one set...
awk... the shipping cost is higher than the clips...:mad:

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?

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.

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...

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'm using bios 1021.006 on my p4p800 vanilla (non SE) and it works flawlessly with my 780ES. this new bios adds the vcore adjust which is absent in bios 1021.003

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?

Salu2

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.

PS: alom zhe ge jr bu zai gz upload pics. jingran pao dao zheli fasao. bs

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
CT-479 $42: http://froogle.google.com/froogle?q=ct-479+ewiz

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.

I think I'll just go with a trusty Northwood.

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...

sweet, might have to shell out the dough then
