In very simple words is a feature to lower latencies on the memory controller. Is a way to differentiate the higher end chipset (875) from the mid end (865), but you can fully activate also on the P4P series using some options in the bios. There are still some small drawbacks but I don't know what and why.Quote:

its defenitly holding you back! i can run 260x? and others only run 250x? with pat on! :(
try not me and others, try you with pat on and vs. you without pat :) then talk :)
So, PAT doesnt really matter to me, because I have P4C800-E Deluxe? I was just wondering, because 220x12 is prime stable, and 221x12 it fails after 1 minute.
did anyone experience this phenomenon with corsair XL 512:
my 730 can reach 2.6 (fsb217) with one module, but only 2.46 with 2 modules.
it seems that tccd works better on single channel, but as other said bh5 suits better...
My 730 reaches
2500MHz without VCore increase
2,6GHz with 1,30V.
2,7GHz with aren´t stabel with 1,6V :upset:
But i think the 2,5GHz are enough for the most games ;)
What cooling are you using ? For 1.6v you need a very good air coolerQuote:

Yes, but this is not critical in my experience...
My Dothan 730 did not get any cooling at all (almost) in my first defective P4P800 SE board...
I could bench at 2520 with a Zalman "resting" on the core.... reaching temps of 65-75 without any problems..
As we all can see from many postings in this (and other) threads about Dothan OC.. You just hit a wall at some FSB... and raising VCore etc. has little effect (if any at all).
It just give You some more "peace" to see the load-temps (on good air-cooling) stable out at 38-42 in Prime'ing.. but 70 degrees goes just as well..
Of cource.. using "phase-cooling" and benching at sub-zero with high(er) VCore will give results...
Edit:
You may ask why I just put the cooler on to the core... Well... with my first board.. it just shut down when any pressure was applied to the socket.
And I just had to do some testing... :)
(The "mobile" CPU's sure take high temp's with ease..)
My 745 does 1.6V fine with a tiny chipset cooler (Swiftech MCX159). Loads under 30C priming (at 35C it will reboot no matter what the vcore - will reach that at 1.7V). Mind you that's from the bios on an 855GME-MGF, given that it idles at 9-15C with roughly 12C ambient temps, chances are its reading a bit low. The heatsink itself is only mildly warm on load so it's still pretty cool.Quote:

I use the stock cooler .... i tested only with 1,6v if it is stable and maybe for benchmarks and nothing more.Quote:

Gaming performance-wise, how much would I lose if I only ran 200FSB 1:1 as opposed to 250+?
edit: Priming @ 187x15 @ 1.525vcore now.
Edit2: Looks like it will be prime stable @ 2800mhz with the board drooping as low as 1.5vcore.
Well new ct-479 arrived and still exact same problem with my 730's. Guess I'll try another board (the only cpu I tested the p4c800e-d with was the origional 730 which apparently cuts out right at the FSBx12 that I'm stuck at, and didn't support multi adjust when I tested it, so maybe I was hitting that cpu's max and assuming it was a FSB max) then call it quits.
On the plus side, I can now offer a decent combo deal and get rid of this board, my massacred ct-479 and my B1 725 all at once.

And about those mem clocks, it could be the memorycontroller :)

because the memorycontroller will crash at a higher fsb, could that be?

the NB get his voltage from the vagp or?
Vagp mod seems to give some boards a boost so try it out :) BTW, very nice CPU speed :)Quote:

OK a little update.
I have now recieved a newer m-740 than my previous SL7SA
pack date 05/28/2005 , batch 7514B588 .
I can now POST at 250mhz FSB , where as before (same mainboard/CT-479/etc) I could'nt post over 235mhz.
So IMHO its the DOTHANS that differ allowing different POST FSB's.
http://img.photobucket.com/albums/v3...33/PIC-002.jpg
Look at the vcore ;) , stock air :)
I stopped prime95 and it had been running for for 1 hour when I did, this pic is just to show the drop in vcore under load.
I have to do some more testing but I think I will chose 13*200 as my 24/7 setting because of the PAT problem this mobo has. Vcore is set to 1.3v in the bios and drops to about 1.25v. I also tested 1.275v in the bios but this failed to run prime95 at 2600mhz. There is another option between 1.275v and 1.3v that I have to try.
Just to keep the thread alive.
I can't go lower then 1.5 in my bios with a P4C800E-Deluxe Bios 1.23
I wish I have the one which does 2.6GHz stock and with Vcore lowered...
As I said, awesome chip !! That one really needs some decent cooling :)Quote:

Hey Razor Sniper.
I have essentially the same system you do for a server. Can you do me a favor and run a 3dmark 01 for me. I get about 27k. Is that about right for a default install of xp pro and that setup? I would think it would get a little higher, but I have nothing to base it on. My 6800gt overclocks to 412/1150. If I put some cold air on it or upgraded the stock heatsink on either the vc or cpu, I probably could get more out of it. It is supposed to be quiet and it already is too loud for my wifes taste at night. Keep in mind, an overhead ceiling fan is too loud for her as well. I have a panaflo 92 mm and the stock ct-479 cooler in place. Those together are too loud. I have an Antec 350 watt PS that is pretty quiet but it has 2 fans in it as well. I guess I wil buy a Thermaltake Typhoon for it. I just am not sure on the mounting....
I don´t want to open an extra Thread for this.
My Dothan reaches 2.5ghz with the default VCore. And 2.6GHz with 1.42V but if i want to reach 2.7ghz it isnt possible even with 1.6V. Are these resaults good for a Dothan 730 although it doesnt reach 2.7ghz?
Seems about average or even a little above. Mine does the exact same and it is a 740.
My 01 score:Quote:

BTW, my dothan only reaches 2700mhz, but isn't benchable... Think the problem is with the 730's and it with will only go higher with subzero temps. I gained nothing with watercooling...
Anyone here with a P4C800E-Deluxe Rev2 Bios 1.23 and can set a vcore lower then 1.5? If I set auto is takes 1.55 :confused:
Well what the heck am I doing wrong? I don't even get 27k evenly. I am running 217x12(2604) @ 2,3,3,6 in dual channel mode. When I run in enhanced mode, it still is not very good. I think I am missing soemething major. What are your 6800gt clocks at? Mine are at 410/1120. I am kind ticked off now. 44 mhz should not give you 2500 points in 01. What kind of tweaks are you using? DO you think maybe my drivers are bad? What forceware are you using? :eek:
77.77 that run... But it doens't matter much... I have lod set @ 3 and a few windows tweaks, not very special... If I set lod @ 0 my score is 400~500 lower.
Well I have never messed too much with the LOD so I guess that could be part of it. I will have to try tonight for better. I see you are running directx 8 and windows 2000. That is probably good for 1500 by itself.
I'm getting an old PCI card in about 2 hours from now. I hope this fixes some problems with my P4P800 SE and I'm going for 24 secs on stock air this evening if I can run PAT at high fsb with the PCI card.
I hope it does help. I've got prolly the same bad rev P4P800SE as you. Doesn't have locks and PAT with X800 :(Quote:

Stupid Asus not locking AGP frequency when booting at 200mhz fsb. Maybe I'm gonna flash a P4C800-E Deluxe bios in it. If the bios works at this board I guess this fixes the problem.
It would probably max out at 2800 Mhz air cooled anyway. 98% of all Dothans do that.Quote:

With the P4C800-E deluxe there is no reason to boot at 200mhz fsb. The 875 should keep PAT enabled when you boot above 200mhz fsb.Quote:

And what about the 865 tweaker beta? Enabling PAT doesn't seem to work so is there going to be a final version EVER with this option working?
I don't know why but booting @ 200fsb is faster then booting @ 201 fsb...Quote:

OK new pics.
I was able to run at 250 memory for the first time tonight. 5692 on sisoft and here is my best superpi 1m so far. I was at the 17th iteration and it quit for what it looked like would be a 28.1 second run. Easily into 27 with some tweaks....Anyways, I am happy. The reason it is faster when booting 200x10 or 11 is that pat is enabled and the memory is running at a lower latency...at least that is the case for me. I can run 240 @ 2.5,3,3,6 and get 5500 on sisoft.Memory is slowing me down a little bit it looks like, but I can not complain.These geil sticks cost me $100 from the Egg and they are 2,3,3,6 up to 220 and 250 @ 2.5, 3,3,6. 2.85 volts. (2x512)
very nice . 26s at only 2600 . It is better than most of 2800Mhz i`ve seen so far .Quote:

Wow, you beat me by more than 1 second with going from my 238 2.5,3,3,6 to your 261 2,2,2,5 with the same exact clocks. That is wierd looking though. It was averaging 1.4 seconds between loops until the 10th and by the 16th, it was doing it every 1.2 seconds. Is that scaling up performance? Impressive to say the least. :)
Good job!

What do u guys think ?
Notice how bad my latanceys are,
and Iam using 4x512mb of ram
So that will be slowing me down alittle.
slightly confused on the screen shot, howcome cpuz shows stock clock at 1.86ghz when the cpu is a Dothan 745?
Maybe this "old" version of CPU-z has a problem to show right values. But on german forum I found some other CPU-z screen which showing wrong values.Quote:

yeah, mine p4c800e dlx does the same, you cannot reboot, but it boots once you power it down and then on again, no need fro cmos though
you have to lower fsb with clockgen without rebooting.Quote:

I can confirm that both the AGP and PCI lock are NOT working at the Asus P4P800-SE when you boot at 200mhz fsb :mad:
they're locked if you use nvidia agp or whatever pci video card.Quote:

No they are not. With a S3 Savage I get some nice screencrap when I up the fsb from 200mhz to 220mhz when I boot at 200mhz. And with my Nvidia card I'm pretty much 100% sure that PCI isn't locked also. The ATI cards just have a lower AGP frequency tollerance, as has been shown before on other platforms.Quote:

New retail 740 is here and I'm praying I dont Jinx it... but priming @ 212fsb 2552 (dropped to 12x multi) now... wish me luck... one thing though... DAMN it's running hot. I probably need to clean the old thermal goop (arctic alumina) off my heatsink and reseat it with a completely fresh layer.
EDIT: FINALLY FIN-A-****ing-LY I got this dothan rig above 2500mhz... and it only cost me about $1600 in parts to do it. Definately was the CPU's to blame. They were ALL Dell pulls from, 9300, and possibly all from the same Dell "deal" on 9300's and also possibly all from the same batch (though the last two are just suspicion). So if you're hitting a similar wall... buy new cpu's preferably retail ones... until you get past it. Sadly, that's probably the most economical solution.

Yes... yes... I saw the Terrance and Philip movie... now who wants to touch me?
Well at least that was not random... :stick: :stick:
Lithan what is the story> What kind of cpu did you get?
740. priming/burning in @ 2900mhz right now. 1.52vcore min so far, but I suspect it will have dipped to 1.5v by the time I get up. Going to bed now. Errored at 26X*11, so I'm at 24X*12 right now. Once I've got a nice burnin, I'll see if I can squeeze some more out of her. I'm hoping I can get a p4gd1 to play with.

Well you have spent enough. You deserve a good one!!!
Dothans are strange... 1.285 vcore and 2684 mhz and wit 1.6 vcore I can't get a mhz higher... Try'ed everything already.
Hey guys i'm trying to find out if the Asus P4P800-MX mobo is compatible with the ct-479, anyone have any experience or know if it is? Thanks for the help
Whoever said mounting a other than default heatsink on a dothan was easy should get smacked! :slapass:
I spent 5 hours today mounting my old Zalman CNPS 7000cu to my brand new and first dothan.. When I finally got it right I was so happy I almost cried :p: That mounting is a great piece of engineering I tell ya :P Anyways the 740 (packdate 07/08/05 "RH80536 / 868608 / 7522A456") is doing pretty well on my P4C800E-Deluxe..! :D Screenshot below is max achieved today, and was not stable. Now I'm priming at 250*11=2750 MHz at 1,4 V and it's liking it :) The temp while priming is stable at 42 degrees celcius - and that's with the zalmans fan at 60% ;) Totally quiet :D
However my cpu doesn't like FSB over 250 MHz! Why is that?

Maybe you should smack yourself :p: (no smack myself icon :(
Including the modding of the ct-479, it took me a whole 30 minutes to remove the stock heat sink and mount the 7000 heatsink. Does work great through!
I just followed the instructions from charlie as he posted them. I read them like 5 times over two nights, looked at the CT-479 and the 7000. Pictured what I should do, etc.
Clips upside-down made it far too high up! One of the reasons it took so long time is probably because I tried several different approaches before I found the lucky formula. I didn't follow any guide. During that time I also biked to a store and bought something I could use as plastic washers.. too bad it didn't work at all using them :p: I also dremeled on the clips to flatten them under to make them fit into the retention frame together with the adapter, just to find out that cooler didn't reach down to them there :P
Also, bhoward I think the orientation is different on the p4p800, and somewhat easier.. :p:
Well anyways I'm probably just incredibly nooby! :p:
Dothan rocks :D :toast:
Edit: Does anyone know something about the 250 MHz FSB issue?

Glad to hear it man... I finally broke 2.5ghz today. Turns out my 730 scales to voltage better than I thought. I thought I had it maxed out at 2.5ghz but today I blew that out of the water by going 294x9 @ 1.45v :D. After I get a better heatsink on this thing I'll put 1.5xv into it and see if I can actually do a 3dmark2k1 run at around 2.6-2.7ghz :)Quote:
