uclajd, Im getting some wicked behavior from my P4P800SE as well.
Now and then it wont boot, then it needs some time, then it boots fine. Sometimes I need to tamper with the fan connectors to get it to boot.
Then it gives me the "chassis intrusion" message, then dont. This is with a regular P4 chip. This board is even worse than the K8N Neo2! But I'll get that piece of junk to comply. I swear it!
U can use Asus uptade winflash program... no corrupted floppy problem.
Got my adapter and 730. 2,6GHz seems to be about the max for this chip with conventional cooling. Damm Asus P4P800 SE board looses the agp/pci -lock wit ATI -card when booting 200FSB. Bootin 201 locks them but looses the PAT -latensy enhancement... kinda sucks. :mad: ...doesn´t help much even when performance mode is enabled wit Tw865 -memtweaker. About 10ns slover latency, 60MB/s slower memory write and 450MB/s slower memory read measured with Everest home -benchmark with 1:1 217FSB PAT vs no PAT.
People with dothans 2.4+ what are your temps around. I hit 50C and i was wondering if my board is jacked up or it is actually that hot
On the stock cooler 50C+ is typical.
18 c ? On boxed cooler.Quote:

Sub to thread
After killing one Gigabyte X800XT PE, i just recieved another one yesterday.. So..., time to put my Dothan 750 to the test again.. After doing the Vcore mod on my P4C800-E DLX i have all the voltage i could possibly want.. :D
It also helped that Overklokk lended me his Mushkin pc3500 level II sticks of memory..
I used Eist to increase multiplier, ClockGen to increase FSB, and the 1022.003 BIOS, Cooling provided by an OVERKLOKK modded MACH II @-50 deg. C with Chilly1 evap. Videocard is a Club 3D X800XT PE which turned out to be a lot better on air than the Gigabyte..
But, NO DOUBT, the Dothan rocks bigtime. Seems (to me) that the Dothan is a lot easier to OC than some of the newer processors from the same producer, as well as those of the competittion..
Well here are the results I got.. Quite pleased actually, considering the fact that there were no mods on the video card, and stock cooler..

Very pleased... tuesday i get my OVERKLOKK videocard cooler too.. with chilly1 evap as well... :banana:
I would recommend the 740, as it is between the 730, and the 750 has a bit high stock mult (would need to be able to do 2.8GHz on stock multi when booting at 200fsb).Quote:

K, I am ready to kill myself and this rig. Would probably have to kill the rig first, because otherwise I'd be dead.
This F'n card keeps causing shutdowns under load, and isn't clocking like it used to. :upset:
Anyway, so far I am at 37124. Sounds nice, but this card has clocked so much higher, and never used to cause shutdowns like this.
I feel for you my friend! Is it too much to ask, to tell you to keep on fighting?Quote:

BTW, Im posting from my rig now! Finally. Gonna do some stock benches and then turn up the heat. Need to get my booster and BH5 sticks rockin' as well...
Update: I might be looking at a quite nice CPU. 1M stable @ 2550MHz with stock voltage and stock cooling :D
Finally got my dothan rig up and running. My combination is P4GD1+CT479+730. Everything is working really nicely and totally stable with Asus X800XL PCI-E graphics. At the moment I am at 2.4Ghz with default voltages and 200fsb. Haven't tested for higher clocks yet. I am quite happy with these setting and will probably be running it like this in everyday use. But I am going to try some more oc action in the next days and maybe post some pics. I did try SuperPI 1M and got about 30.9s which is about what it should be I quess at 2.4Ghz... :)
Sounds nice... wish we could get P4GD1 here in the USA.

And some updates on this end,
We MUST find a way to shim these cpu's... after monting evap and remounting about 10 times I have SEVERAL cracks across the top of the core on my cpu... of course it still works, but this needs to be resolved.
I have some .025" aluminum sheet that is .8mm, nearly the exact same as the core height above pcb, .83mm... I will try to get my neighbor, the machinist to make me some shims!

Very nice indeed.. just remember to change the "pcie freaquency" as you can read in here: (thanks kamerat)Quote:

My best Pi run so far @ 27sec... I need PAT to be enabled!!! :slapass:
Got the Zalman 7700 mounted, even without modding the adapter. I simply used the bracket from a 7000 turned upside down and some long bolts... Works really well! I would even be willing to mount this inside a case :)
Gotta figure out how to get more from it. Need to do some mem-testing as well.
How ironic that the 300x9 run I always hoped for but never got on my A64 rig should be realized with an Intel chip :D
I haven't been able to get 5:4 to work. How you doin that? What did you boot at? What board? :confused:

But there's a lot of quirks to this board in my experience. I seem to hit a wall at ~2700ish. Let me know if you need more help uclajd :)
This 7700 on the Dothan simply ROCK! I run in at lowest RPM and get 32 degrees idle, 40 degrees load. Silent as a breeze. Need either droop mod or wiremod to get enough vcore. In drops below 1.55 during load when set to 1.6 in bios...
We need not to loose PAT on the 865PE chipset above 200FSB.
Is it doable at all? A Bios update? Any suggestions?

Thanks stryg, we Dothanites need to stick together. ;) Jeez, I really need to try this (Charlie, have you tried this? You have similar clocks to mine). I think my previous problems might be that I was booting at 200, not 201. Is that an arbitrary little feature or what?
I never thought I would say this about a 37K 2001 score, but my rig is seriously underachieving. I woke up this morning and my hair was white. :lol:
I know I have 40K in this rig. I just want to hit it before someone else hits 50K, which the next gen cards are sure to do - if Kingpin doesn't do it with his 850.

Any experiences with the new P4P800SE bios?
Im posting from my laptop, uz my board tells me I have a new CPU installed, and that I should enter bios to set it properly up! I get that message EVERY time i boot.
Im gonna try the new bios, see if it helps...
Hi, just read on the first page of the thread that with p4p800 its dificult to get above 170FSb, is that really true? any chance that a bios update give us p4p800 official ct-479 support, not beta bios crap?
Wuld you recomend going with p4p800+dothan 730 or isn't my board ok for, let's say 2.5-2.6 overclocks?
Thanks guys
They have official bioses with ct-479 support but they suck monkey-balls.Quote:

If you have a P4P800 board I would stick with it.
But if you're buying a new one and/or you funds allow to buy a new one I would get a P4C800(E)-(Dlx) or an P4GD1 :)
I need to clean up on the frontpage.
Is it fair to divide the P4C and P4P boards into two categories instead of P4C800-E, P4C800-E Deluxe, P4P800SE, P4P800 and so forth...?
Any suggestions as to how to make the frontpage more clear are welcome :toast:
Not yet, got some real work to do today. Then (maybe tonight) I am ripping the cascade off of the X800XTPE, which BTW is pissin me off to no end, and putting it on the Dothan. Let's see what she can do at -85C and a new BIOS. :slobber:Quote:

Nah, I can go 274 (at least) on my board. I think this new bios that allows you to set the multi in the bios is huge if it works. It no longer means that the 760/770's are only for phase change, since you don't have to boot at 3GHz+ to get the 201 FSB features (additional ratios, locked AGP/PCI).Quote:

Never thought i would ever see 38k :banana:
Yes sir! Im back in business!
Found out that the small poles holding the mounting frame were pushing very slightly to the adapter from the bottom up, due to the fact that I had the board laying on the box it came in.
Now, I simply mounted the small "she"-screws that normally holds the board to the tray so that it rest on those. The board is now nicely elevated from the surface eliminating the issue...
What a noobie-mistake :D
But I got it sorted out :)
Now, we seriously need to figure out a way to get PAT at 200+ FSB on that 865 chipset!
Great scores, congrats, but jeez get some improved RAM! Even 2.5 could put you into the 22 second club, and a lot of RAM will do 2.0 at 261. I've ordered a RAM booster for just this.
What clocks is your card running at?
You have me motivated to go cascade tonight, but I have work to do!

Do you know about a new bios for the P4GD1? (like 1006.03 or something)
thanks.
An OVERKLOKK modded Mach II with R507@-50 evap, with Chilly1 evap. Works like a charm.. The videocard is completely stock as far as cooling goes, but the clock was 590/595..Quote:

Did you have any problems with your mobo? what bios were you running? Want to go for dothan action but don't know if my p4p800 std, (non deluxe) would work ok.
I've had an eye on this thread for a while...
I have an P4C800-E Deluxe, and a MachII. What would the ideal CPU (740/750 etc..) be, and Bios?
Cheers
About the P4P800/AGP/PAT issue...
I was thinking about a workaround. What if the CPU is recognized as 200 MHz FSB? Then maybe PAT will work above 200...
Remember Athlon XP used with Abit NF7 and other nF2 mobos? You could reach higher FSB OC after making a U-wire mod, making the CPU recognized as 200 FSB. The situation is not comparable but you get the idea.
The difference is that there's no 200 FSB PM, but back then there were 200 FSB AXP, so the BIOS may not like the mod, but I still think it's worth the try!
In a similar way we have seen drawbacks with having the FSB jumpers set to 100 FSB (instead of 133). The bigger difference between the recognized FSB and the actual FSB, the more trouble >>>> raise the recognized FSB!?
...or have you already tried?
Another nugget for the CT-479... annoyed with the noisy 70mm fan on the stock CT-479 HS/F?? Pick up a 70mm>80mm Fan Adapter... and swap it out for a quiet 80mm fan and gain about 10cfm.
C
Just flashed to the latest bios, full multi control available (though cant see to boot at 6*) 12,11,10 and 9 are all fine, will test lower in a bit.
Nice work asus :D Should mean the higher multi'd chips can be booted at 200 fsb now.
Anyone have a 400 fsb chip that can be tested, see if they boot at higher fsb's?

Whats the easiest way to get stable vcore on the P4P800SE board?
I suspect too much fluctuation to be holding me back...
I cant get above 2700MHz no matter the vcore.
It's equally stable at 2650 with either 1.5 or 1.6 vcore...

In fact, you are correct Intel seems to prefer XP over 2k, though sure someone mentioned 2k might be good for ~ 100 points more. If you run a fullly tweaked XP, boot in diag mode, run a services killer etc, sure its as good tbh.
Yea the older cats seem to do a little better 01 wise, ran those as they were on from a 9500NP @ pro softmodded bench, just wanted to get a rough idea of what the card could do..

Last question here, that mulit option looks awsome, but can you go higher? Is say a 730 capped at 12 multi and lower, or could you do say, 13 / 14 (worried about 1:1 ram as mine maxes at 250 atm). ahhh look at me, I am worried about all this and I dont even have the cpu yet :p: Dothan madness I say. Its like an A64 in Intels best chipset (875) :slobber:
Nope, as with the A64's the chips are unlocked down only, so no 12+ options on the 730.
Check how bad the vdroop is on your board, some chips dont like over ~ 1.55v so running 1.6 should put you about that.
N-lite the install, remove everything thats not needed. Kill services, high priority, ricky tweak. Thats about all off the top of my head, others will know of more for sure. Running order can make a difference as well, DL, LL, CH, DH, LH, N and re-run CL seems to work best. Everyone has their own favoured order though :)Quote:

My temperature at idle is around 45C and running Prime95 its goes up to 65C. Is my temperature too high?
I try lowering my RAM settings but that didn't help. Can someone help me?
Temps are a little on the high side, will it run 2.4 at any lower voltage than that?
Would be worth getting some better cooling on there if you cant drop the volts tbh, see Charlies thread below for more info on that.
It could be that the cpu is just maxing, the 533's seem to do this as the 400's do with FSB.
Dropping temps should allow you to OC a little further though (unless the cpu IS maxed) 1.6v is a LOT for *only* 2.4ghz though.
I can use lower voltage to run at 2.4 but I'm trying to get to about 2.7-2.8 on air.
I have the Zalman 7700cm that I haven't installed yet. I'm waiting for Charlie to post some pics on mounting P4 cooler onto CT-479.
I'll try lowering my voltage and see if i can get higher clock.
Is it better if I go to 12 mulipler or stay at 11. The reason i went to 11 was to get better FSB since I can't seem to pass 2.5Ghz
If you cant pass 2.5, with the higher multi and those volts, then chances are the cpu might be maxed. Better cooling might well help you out, but dont be surprised if it doesnt. This 730 is maxed at 2.57ghz stable, tho burning in does seem to be helping a little, can pass pi at 2.61ghz now, where 2.57 was the max possible before.
Shouldn't the 750 be better at OCing than the 730?
What is your CPU temperature?
Its all luck of the draw. Just because a CPU has a higher stock, doesnt mean it will clock further.. Look at the 3000 venices for example, most hit 2.6ghz, with the good ones hitting 3+.
CPU temp is 49 deg, thats after 3 hours of prime, with cpu fan at 80% on the stock cooler with 1.35vcore (201*12)
I too seem to be hitting a brick wall at 2.5ghz :(

Does 2.5ghz ON STOCK VOLTS! But trying to up past this to 2.6 etc, taking the volts upto as high as 5.75 just freezes the computer :(
My memory isn't the one maxing out cause I can drop the multi down to 10 and do 250mhz... so it's the chip which won't do a higher clock speed.
Oh well, it is the first day of me having setup this rig, my memory isn't burnt in and hell, the systems only just been setup to be honest. I'll continue to tinker :D
I haven't really play around with the voltage after installing the new bios.
I'll try lowering the voltage to lower the temperature. I'll set the multiplier at 12 and see how high I can go.
okay... time for some more indepth testing *installs the 3dmarks* >:E
ps: 3 in the morning here... got work at 9... de dums... :p
pps: what's really annoying is that I set myself a goal of a sub-27s superpi... unless I figure something clever out with this gear, doesn't look like I'lll hit it :( Might be able to achieve it by lowering the multi and upping the fsb to increase system bandwidth... depends how far off 27 i actually am in that last 1s.
results: 2001 => 28,656
2003 => 13,792
2005 => 5597
had to boost my vcore from default to complete a run of 2005...
I'm new to the forum, I only want to tell everyone thanks for useful infos.
Mostly the new beta bios for the PC800-E that allowed me to make futher experiments without U wiring.
I already had a sony Vaio fs115S (FS550 in USA) where I obtained:
Dothan 1.7 with fsb forced to 533 = 2266mhz rock stale at stock voltage, mybe a little hot on heavy load but undervolted better.
So I suddenly bought a PC800-E and the CT-479 to make a silent server for my home as I had the old notebook's 1733 Dothan.
At first tryes, not bette than 2400 mhz, because of wrong multipiers in MB.
But, with the new bios
a wopping 2612 mhz (201x13) at first try and at 1,41v, max temp under load 52c with stock asus heatsink.
Now all night long running ok.
I think Intel has some surprises on dothan architecture, because it's too easy to overclock that it's retained underpowered I think.
Again thanks to All

new bios? which one??

Anything above that, it'll put out a pi run or 2 but thats about it.
Primed overnight (still running now fingers crossed) 2.4ghz (201*12) on 1.35v set in bios + vdroop. Windows is reading 1.31, is there a read point for vcore anywhere to check what the actual voltage is?
New bios, check back in the main intel thread ;) One for P4P and one for P4C

i have a really bad problem with my daily use HD, if i open asus update utility, task manager or if i tri to linch regedit or msconfig the program start but disappear in 2 seonds...i am disperated, i have run 1000000 antivirus, done a so repair but nothing to do :(
ideas/place to ask for infos???
Is it a seagate? IF it is go to their website and download seatools, then run the repair one. It solved my problems with my HDD.
no, but i said HD to say daily use OS, win xp with games internet ecc ecc...i think end /OT, i will search... thx the same a lot!
