Having the same issue lithian. Above 2557mhz it reboots. Burning in has helped a little though, can get 2.6ghz boots just about now :)
Using stock cooling? Im thinking with upgraded cooling maybe it will go away.
ive noticed all who are running the p4c800 e dlx like me hit a wall around 2.6 . ive just managed to put the vapo head on and still no gain . i could do 2,5 with the org cooler . anyone getting higher with a 730 on a p4c800 e dlx ? i to get reboots after 2,652 ghz no matter what ram or cooling
p4c800-e deluxe rev2 bios 1022.003
m730 at 2750 12x230 1.55v.
it gets unstable at 231 and above when the cpu is stressed.
1.64v made no differance.

This is very dissappointing. Im hoping we find a fix quick. I had high hopes for this cpu.
edit: As I recall, 1008 forced me to use the bios it had been set to when I flashed to it (except on a "system crashed due to OC'ing hit f1 to enter cmos" boot wherein it used 1.3v). So once I upgrade cooling I might just set to 1.55v or so, and flash back down to 1008 and see if that fixes my maxx overclock problem.
I do think 1008 has pentium M microcodes.... :stick: :nono:
I have the P4C800-E DLX mobo, with the 1022.003 bios, and right now i am benching 3200mhz using an Overklokk modded Mach 2@-50 C. :banana:
The cpu is an M750 dothan and i am using Mushkin level II blach 3500 memorysticks..
Super PI is done in 24 sec (soon to be 23...) in 3d mark 01 i just pressed 36 000, with an unclocked X800XT PE ... This setup rocks bigtime.. Pictures will follow...
nice clocks there.Quote:

Maybe the chips just hit a wall?
hey do you have a link for that beta 1022.003 bios for p4c dlx? I did not find on asus site...
ftp.asus.de/pub/ASUSCOM/BIOS/Socket_478/INTEL_Chipset/i875p
they always have the new bios here before the .com site

I'm almost embarassed to post this, as bad as my RAM is holding me back. I just can't get it to finish @ 2.5, so 3.0 it is:
http://209.35.180.29/misc/dothan/pi25.jpg
This is under stock Vapo. Eventually will use the -85 cascade on it, but first, some 3DMarks...
just got an adapter, so son it will be P4C800 dlx + ct-479 + default cooling.... atm.... will notify on results. oh by the way... I have dothan 1.6@2.13 on asus Z7100Z notebook :) - they have jumper for 533FSB :)
one question... what is better for overclocking with ct-479? setting jumper on 400 or 533 FSB? does ir have any influence?
Mine clocks 5fsb better at 400setting.
Did some 3DMark01 testing on my Dothan @ 2.6Ghz (260x10)
http://service.futuremark.com/compare?2k1=8614821
Not bad for 300c / 700m, with 12 pipes ....needs OC'd now...
BTW. superpi 1MB at those settings is 27.813sec
just got my dothan up and running. it does the 2.4 at stock volts.
http://members.accesstoledo.com/gabr...2400dothan.jpg
I just ordered a Zalman ZM7000B-AlCu for my Asus-Dothan combo. I also ordered a 80w (16v) Peltier element to experiment with. As I don't have any previous experiences with TEC I'd like to ask something:
-I'll be taking power directly from my Enermax 485W 12v line, I think I have enough wattage overhead to spare. 2x HD, 2x DVD, R9700 and Dothan are the power-consuming components. Comments?
-With aforementioned power I think that the element is definitely enough for Dothan but do you think the heatsink can handle the load? If I've thought this correctly the combined thermal power of the peltier and CPU shouldn't rise much above 100 watts which is in Prescott region.
-Am I going to hit sub-zero temperature readings? What about condensation then?
-Any thermal greases needed?
Any other comments, tips and tricks related are welcome.
what ram timings are useing that seems kinda slow @2.4ghzQuote:

then spend yesterday night and today in the morning getting all ready for phase change benching and bam!!! no post... :slap: trying to figure if i forgot any cable...nothing...all well connected....clearing all insulation again....:slap:
there was no condensation at all and no cracked chip....no nothing...just it does not post...but i don't know if it's the chip or the adaptor (board runs fine with some spare p4)...and i thought it was the best insulation i had ever done...and i :banana::banana::banana::banana:ed it all... :rolleyes:
i hope it can revive...so i can do some real superpi and also some 3dmarks...:D
anyway....GREAT cpu....!!!!!!
evil_raver -
Check to make sure your not grounding out on the adaptor plug. (Top and Bottom of plug)
My guess would be if your rig isn't doing anything (no fans, no nothing) then you may be grounding out somewhere.
thanx a lot for your tip runmc.... :p:
i'll check tomorrow in the morning...well..the systems starts (fans spin...even keyboard leds light up) but screen just doesn't work...it stays on no signal screen....it reminds me when i killed some years ago a p4p800 with condensation....this time board work for sure though as i tried it with other p4's....
i'll check adaptor as you said...and i'll connect pc speaker from a case near the bench rig to hear if "asus bios little girl" has something to tell me about it.... :D
have just put P4C800 dlx, ct-479 and dothan 740 (1733MHz) together with the crappy stock heatsink/fan combo.... now it runs at 2157MHz at 50C at its 1.325V. when changing under windows it craps out if I put like 170FSB even with multiplier lowered... :( It is able to post at 201FSB at 1.600V but only to post... :(
what can I do? is there any other heatsink, which would be all copper and fit this combo?
try to put the jumper on fsb 100 instead 133, it might help!
where does it come from, packdate?
yes, the jumper is at 400FSB - I did not change it - it came like that.
packdate?... Well, it comes from my laptop, so I have no Idea. the one I put into laptop at the moment is dothan 725 (1600@2130 at 1.34V and not a notch lower) from philipines and packdate of that one is 05/06/2005.
the one I have on P4C800 dlx is 1.73Ghz and it was able to run in a laptop 100% stable 24/7 at 56C at its speed at 1.052V
and I have put it here because it was said that 533FSB models tend to reach higher fsb....
I have a feeling that it is a cooling that stops me from reaching high FSB...
oh, i was just messing around with it at spd.. te timings were 2.5 4 4 7. ill adjust some of the timings and play with a bit. it did 2.5 (10x250) at 1:1 and did 30sec with the same timings.Quote:

i don't think so, because my dothan 725 @2.4 temp on p4c800ed (bios 1022.003) is also at 56°C (stock cooler undervolted).
you may have a "bad" 740...
is it your cooler undervolted or your 740? :slobber:Quote:

im using vapo . but your problem is the agp lock . you have to boot at 201 fsb .so the agp locks . use the 1022 biose .it sets multipler to 6 . so it should not be any probs booting at 201
guys arrived my new 740!!!
it just fly... 1.35v boxed cooler it hits 2700mhz at 1M pi...
congrats malachia... :toast: that one seems great...!!! now throw it some volts.... :D
Awesome! Put it at 1.6v, RAMMING SPEED NOW!

ok, tryed better
with 1,55v from bios i can close 1M pi until 2765mhz, still on boxed cooler!
now i try to get a good pi score like 25s mounting the ddr boster...
ah, BTW, ambient temperature here is 33°...this little bastard 740 is awsome!
if you have 1022.003 you will boot with the 6x multi...like this you can boot at 201mhz and than you can change the multi in windows with EIST or other programs...Quote:

Thxs,
I think it'll be very usefull to see for O/Cing potential, if the cpu origin is important... ;)
my 725 fron philipinnes SL7EG with pack date of 05/06/2005 ia laso barely reaching that limit and no more with default cooling.
and for the jumpers - it did make no difference as to set them to 400 or 533 - dothans with 400FSB have multi options in bios and dothans with 533 do NOT.
by the way,I have 2 dothans 725:
one on a p4c800ed 1.6@2.4 vcore 1.425v(fsb 160 bios so ratio x15)
the other on a dfi855 1.6@2.4 vcore default 1.34v(fsb 150)

Dr. Ychock
I've got a 730 in a P4P800SE, the chip seems pretty good, it'll do 2.4 at stock voltage. I'm doing 2544Mhz (212mhz) right now at around 1.35v.
The thing is that even if I reduce my ram to the 5:4 ratio I cant get past 217fsb. Even with the fsb at 217, the voltage at 1.6v, and raising the fsb in windows, when I raise it to 218 it won't take very long at all to spontaneously restart.
Of course I can change the multi in windows too and then raise the fsb past 217, but I'm still stuck with low cpu speed. Dunno what to blame. The cpu shouldn't be hitting a hard wall like this.
Shadrag: Is yor agp/pci locked? ..if you have Ati Radeon card and you boot up at 200fsb the locks dont work. U hav to boot at 201fsb.
Yes my card is ati and I didn't boot at 200, everything was locked according to the clockgen.
Shadrag,
can you tell us your cpu origin & packdate? Thxs!
My quess is that maybe your CPU -has simply reached it limits. Generally OC-ability seems to die suddenly after a certain MHz point wit these Dotties.
I would say past some point in FSB, cause my 725 cannot bot at more than 150FSB be it 16x multi or 6x multi and 740 looses stability after 170 FSB, even if you use 13x or 6x in windows.Quote:

I think there cannot be any difference on top of which bios you flash right?
try to use the last windows update utility, i used that and all worked ok! :)
I have used asus update 6.03.01... is it the last one?
No, last is 6.07.01.
Could anyone who has tried the adaptor with p4p800 std tell if its any good?
have tried that version, have tried afudos again... no way I get that multi option for 740 dothan... :( everytime after reflashing with 1022 version I get checksum error during the first boot, but when ajusting bios settings that dissapears.
are there any tricks to get that working? guys, the ones with dothans with 533bus please, attch your working bios here in a zip or rar archive, please... p4c800-e dlx of course
This
bios as posted by bigtoe in another thread gives mutli options with the P4C800E's
original thread here
http://www.drunken-student.co.uk/pic...1_023_beta.jpg
thanx, will try now :)
bcn
use floppy when flashing
try this comand
"afudos /iromname.rom /n /pbnc"
thanx! I have just reflashed from windows that 1023 beta bios, multi now works in BIOS and I have managed to boot at 201FSB, but...
then was it a BIOS bug, or is it really AGP not locked when booting at other speed? then setfsb and clockgen are wrong????
first screnie :)
If you set fsb to 200 or less and try and up it via clockgen, the PCI/AGP locks arent engaged. Boot at 201 and they'll lock fine.
ok, now have started priming at 201x12=2412MHz at 1.45V in BIOS.
what about booting at higher than 201FSB? - I could not boot at 230, but could up from windows up to 245 with setfsb and run some benches, though it locked when I uppped it to 250, might be the chipset then.... are those AGP/PCI not locked either if it is more than 201??? :confused:
then there is a thing that sometimes setFSB or clockgen crashes if you change it like 20FSB down for egzample.... :confused: is it bug or what?
I have noticed that my 740 does NOT boot with multi set to 8x when at 201FSB and crashes in windows when set.... but boots at higher or lower one. did not try all of them yet with different FSB...
you tell that agp is not locked when booting lower than 201FSB, but then WHY clockgen and setfsb show them as locked???? well, when you boot at 200 yes they show that they are NOT locked, but at 170FSB they ARE.... :confused:
If you boot 201 or above then the PCI and AGP will be locked at 66/33.
Had a similar issue, iirc 8* wouldnt booot at all, 9-12 were fine, didnt try lower though.
Not sure how the AGP/PCI locks work on these boards tbh, only VERY recently moved over to them. Guessing at 170, the board is running a lock based on 166 fsb (ie setting 167 locks the bus) so 170 would be locked.
Thats only speculation though, someone who knows the answer will be able to explain it properly for you.
the point is that I was not able to boot at 180FSB, anything above 173FSB in windows gave errors in prime, but was able to post at 201FSB... well, now I the maximum I can boot is 238FSB (5:4) and currently with 10x ans started priming just now. anything above 238FSB is IMPOSSIBLE whatever voltage I give to it..... though strangely I was able to up to 260FSB (it locked there) with setfsb in windows in small 1-2FSB jumps. I was able to run a 3dmark 2001se at 245x9.....Quote:
Originally Posted by Highland3r

I just do not believe a 875 chipset would crap out at such a low 238FSB, but then again, if it would be a chipset, there would be a graduate decrease in stability and ability to boot when increasing FSB.... :confused:
Has anyone any idea?
Not sure how I managed this:

So I figure it out, that it is not a promise controller, though did not think of an intel one until now... but then how do I disable it? disconnect drives?
I think PSU is out of question, because it would be crapping out randomly... :confused:
then why do you tell without a lock? when I launch setfsb or clockgen, it tells me agp is ok and fixed at its 66MHz.... are they wrong? :confused:
IIRC all the SATA's are locked on the Intel boards as they are controlled by the SB...
As for no boots, thats a random one, however 201 -> is where its at, so wouldnt worry tbh.
well, I DO worry cause I do not like setting all the fsb and multis when booted to windows, I want a setup to boot with the highest options. I will try will less hdds and then will change the default thermal compound of NB to AS3 these days. and will see if anything changes
and Highland3r, what voltage do you use for those twinmos?
I have SATA -drives crapping out on Intel -sata ports when uppin´ fsb to over 210 wit no agp/pci locks on (P4P800SE). Without a SATA drive system works flawlesly to 217FSB when the memory craps out. Hav to install OCZ boostah to get some more out of those new Twinmos BH-5 sticks.
If you use Nvidia graphics adapter the boards lock agp/pci -bus when booting at 200fsb (PAT on), when usin´ a Radeon card they don´t. Wit Ati -card u have to use 201fsb to lock up. Big downside is that u don´t get PAT memory boost then.
Thats why i don´t use SATA-drive in this system... u can try to test the difference for example wit Everest PAT vs no PAT. Huge loss in memory performance when PAT is not enabled and u cannot make it up with TW865 -memtweaker just by enabling performance mode and tightening the RMS latency. Maybe i hav to by a Nvidia -card :(
When agp/pci locks are enabled there really should not be any reason why 217fsb would be the problem for these 865/875 Asus -boards when the memory is not the limiting factor.Quote:

I've decided to give the dothan a try for some benching sessions. However I must admit I know nothing about intel but experimenting is always part of the fun when it comes to Overclocking!
I do need a little advice before I go out in the next few days and waste the money I got for selling my FX55...
Is the P4C800E Deluxe the best board so far for Overclocking a dothan for good results?
Is it worth spending the extra for the high end dothan chips or am I fine with a 760? (will be going single stage, one each for cpu and gpu)
I'll be spending a lot of time reading and learning while figuring all this out and I'll probably be bothering some of you more experienced intel users... thanks again for all your help as always!!! (^_^)
760 is ENOUGH! :) and yes, for going skyhigh FSB, P4C is the best so far :D
yes p4c800-e is the best one!
After all is a 133MHz cpu, couldn't be just a matter of luck (read an extremely good Die) with such high FSB frequencies?Quote:
