I have your board and cpu. I can overclock just a little more than you with air cooling. Water cooling is useless for you. You will have to be in the -C to get any more of an oc. You seem to have way too much voltage also. I set the bios to 1.5 and asus probe reads 1.6. I am not sure which is correct.
Have P4GPL-X + 740M and a P5GDC-Pro.. i915PL and i915P rescpectively..
It seems that these boards/chipsets overvolts quite a bit..
If you set VCore to a value.. "actual" value usually is 0.05 to 0.075 more read from AsusProbe (or any other utility "probin" Bios sensors).
Must agree with previous "speaker".. It is of little use to increase VCore (actual) over 1.55/1.60 unless we're "talking" sub-zero cooling.. :)
I've been reading old posts about dothan and overclocking to see if there are any tips i might missed,
and I have a couple questions maybe someone can help me figure out.
What does VAGP has anything to do w/ overclocking? If PCI/AGP is locked at 33/66, then how dows VAGP help?
Some says VAGP helps system to run stable at higher FSB, but how so?
Anyone has clear answer to whether or not P4x800 series has correct PCI/AGP lock (33/66) at 200FSB?
From what I gathered, at 200FSB, PCI/AGP is indeed set to 33/66, but if using SetFSB or Clockgen, then PCI/AGP divider will not stay lock?
Lastly, what is vdroop? Is this the mod done to either cpu or adapter so it always gives a certain vcore?
vagp also increases volts to the northbridge, thus maybe helping you get to higher FSB..Quote:

Thermalright SI-9XV mounts perfectly with the stock mounts!
Can't test yet, haven't got a 24pin PSU atm...
Can you take a few more picts? This setup looks promising!
But I am a bit worry about if it will stay perfectly flat between the die and heatsink's surface.
From the pict, it looks as though the mounting hook is a bit tilted?

Sorry I'm not much of a photographer...
i cant see it clearly on the pics, so ill just ask; do you need to bend the power pins to the adapter to get it fit?
Yeah, or just remove the pins and solder the power connectors onto the other side - you need that for most coolers...Quote:

Solution: Remove the burnt ground and 5V wire. :D

Figured the heatspreader wasn't making good contact.
Removed it and went to stock cooler.
Still up at 75C.
Shut it off, felt the die - a healthy 30C (approx).
So i figured I have on ****ed up sensor.
So went back to my thermalright solution, got it to 45C in the bios.
Set the vcore to 1.54V.
Set the FSB to 218MHz (max of the RAM).
And made it to windows- just getting the bench stuff ready.
EDIT:
Lol I love this board:
75C idle!
69C load...
:P
Ain't throttling either.
A quick bench in single channel with crappy Kingston Value:

And she overvolts like a *****
1.6V goes to 1.68V
1.65V goes to 1.72V
1.4V to 1.54V
1.5V to 1.6V
Kamerat, what did you use as the shim? It looks like some kind of a foam?
Is the P4P800E-Deluxe supported? And do I have to flash my bios? Cause it won't boot now :( I can see on the asus site that it's supported, but just want to be sure...
yes, it is :)
But I guess not from the default bios? Cause it just won't boot :( And I don't have an old cpu to flash it...Quote:

I have the P4P800-E DLX and my RAID works even though I am using the SE BIOS.Quote:

'elp...
I can live with manual tweaking but not for long...
uh... is the SE bios really ok, don't want any raid issues...
If you use the Promise controller, it won't work. If you use the ICH5R controller, it will work. You really shouldn't use the Promise controller anyway as it has performance issues. Try benchmarking your drives using each and you will shortly be using the ICH5R full time.Quote:

It posts then goes to the RAID configuration and where it typically comes up with the Windows XP screen, it goes blank and does nothing. I have tried the jumper settings for 400 and 533 FSB with no change. Has anyone else had a problem like this?
Using:
P4P800-E DLX w/ the SE BIOS and with the P4Ped BIOS
Perhaps someone has a more positive comment, but isn't this just the perennial overclocking problem of being able to boot the PC, but not make it into Windows?Quote:

Since I am running in RAID, I will try it without. Maybe I will try booting off PATA. I don't think these things will make a difference since I am not booting at high FSB speeds (220 max and usually less than 210).
Anyone have any idea where i could find a guide for modding the fsb jumper bit, so it doesnt stick up, i've seen a few pics but never really a description, cheers
Yes, it's some kind of 3 mm thick "self sticking" foam, not sure what type or brand. Used the same stuff to isulate the CT-479. :)Quote:

Without pot (line 3,3 to Vdimm) it is easy to control Vdimm voltage (beacouse of monitoring line 3,3)

So I started thinking and looking around what I could use. After doing the research the processor is .82mm above silicon. So a 1mm shim would work great. I found a 1.5-2m thicker rubber that I don't think I'm going to use as it is too thick! So I found a gladware container, exactly 1mm thick and semi plyable plastic. Capable of handling 55c easily, think microwaveable, boiling water, etc... Pictures below.
Pic1, Pic2, Pic3, Pic4
Thoughts?
I'm considering adding a layer of electrical tape to one side to up the squish effect under Zalman 9500 tightening. I will seat the HSF and then remove to see how the contact went. I am planning on flipping the S bracket on the unit and will monitor the tightness. Any other hints or tips? I don't see anywhere that anyone ever attempted a 9500 on a Dothan.
Also the EIST util and the CPUMSR link are not working.
Eist is just not there anymore and when you got download CPUMSR the download times out. I'd be more then happy to put these on my domain with unlimited bandwidth as a mirror.
Thanks! PM me if you have it and I'll send you an email addy to attach the file to :)

I did this with some stripped 16 guage wire that I crimped around the stock HSF posts as seen in the pictures below. Final step was inserting a washer underneath the sclip. I am still contemplating a 2nd washer, but have not done so yet. I need to get some feed back on my temps before I try to get the HSF tighter. First my idle temps with 1.6v (1.54v) is 44c, at full load it hits 60-61c. This is at a 13x215 OC. Running Prime95. Temps quickly come down to 44c upon stopping

For those of you who had modded zalman hsf to use w/ ct-479 and dothan,
the clip where you insert screws to mount with brackets has a slight angle makes it not flat.
Do you flatten it out then proceed with tighten the screws or do you leave it untouched?
Left it untouched... you need all the force you can since you flip the brackets it increases the height by about 3/4 inch I wish we had straight bars, that way i could get some clamping force!Quote:
Originally Posted by justthinking
I since have moved the brackets back to their normal position where they droop down but mounted them onto of the existing 478 bracket... it lowered the entire clamping setup about 3mm on each side... it has made about a 4c difference in temps! I was nervous to put that more clamping for down but that is exactly what she needed. Max temps are 52-54 at full load now.
Sunin: You could think of resizing those pictures, they are HUGE....
An other thing is why do you put so much thermalpaste on your CPU? You only need a thin layer to get optimal results.
Well rule of thumb is a bb sized drop... well as I found out the first time that is too much, so I since shrank that down to just a thin strip. When I checked it the last time it had hardly any over spill.Quote:

The way I looked at it, 2w was the max that they would handle but less than that shouldn't be a problem. Most people seem to use 1/4w resistors. I would like to know what you guys think about using 2w resistors for the vdroop mod before I proceed.
So what is too hot for the Dothan? I read 100c on the intel page but that sounds insane!!!
I would rather mine stay below 50 deg but around 60 I get concerned.Quote:

the only thing i find it's weird is my cpu temp, somehow cpu temp stays at around 50-52 regardless of cpu been idle or full load

Hell you both should be happy my P4c800-e doesn't like to post at anything above 240mhz... 250x11 is just a pipe dream for me... I've gotten it to post using 12 multiplier at 230 and that is stable for 2.75ghzQuote:

Next a 3dMark01 run previously this was 24,347 with my 3.2EE Oc'd to 3.6. Now with the Dothan 29760.

Next 1M superpimod runs. Before I could not get past 36.5s, now with the Dothan, I'm at 27.3s. That's a pretty nice increase!
Pic3
Finally 32M superpimod. Pic of the old 32M score, Previous best 35m44s
Pic4
Now with the Dothan 26m51.906s knocking nearly 9minutes off!!!
Pic5
Overall stability is great, I've run Prime95 for over an hour with temps getting up to 54c. Keep in mind this processor is rated at 1.375v and I'm juicing it 1.50-152v under load. Idle temps are around 38c, with 24c ambient temps
I read on Intels sight this processor has a max operating temp of 100c, Am I missing somthing... those are insane temps!!!
Next steps are waiting for a 50k Ohm pot to do the vdroop mod. I'm planning on max of 1.8v, which should translate to about 1.75v at load. Assuming temps don't go too insane! For now I'm happy with the swap and will most likely be selling my 3.2EE since every aspect of my computing experience is faster now! Well I assume multitasking would be slowed now, but maybe not, not sure how I could check that!
try to do an ecoding round, i am sure that 3.2 EE with HT will win...
the perfect cpu is dothan dual core with HT, maybe a yonah with HT is possible?
I know I'm sitting here wondering why Intel never put one of these on a 1066FSB platform with an dual core... I mean honestly this thing rocks... I'm totally impressed. :banana:Quote:
