Been playing around a bit with my new toy :D (Cooled by a XP120)

SuperPI 1M @ 26sec (see pictures below)

A little round of 3DMark01 running with stock X800XTPe

And here is a max SS:

With the thread at 45 pages and me just discovering it. I've flicked through the odd page throughout to build from start to end.

And most people seem to just be using the stock cooler. And getting ~2700mhz.

Has anyone given it a go on phase yet or is there not much difference up to a point?

Plus are there any pci-e mobo's floating around or they all agp?

After playing with a 2nd hand m725 400fsb 1.6 i decided to get a new m730 to test the booting at 200fsb and see how far i could take it.

mobo p4p800-e bios 1007.003
cpu m730 533fsb
cooler xp-90 custom mounting system
ram 2xxms 3500 bh-5

The bios gave me more vcore options then with the m725 but they are still 1.6v max.
I setup the ct-479 and broke a pin so i had to improvise buy putting some wire into the socket and it worked.

Booted into windows at stock made sure temps are ok and the xp-90 was mounted well enough before i started going for it.

Booted at 200x12 first time at 1.5v bios gives memory options of 266,320,400,500,533 at 200fsb.

I set the memory at 320 and fsb at 200 and vcore at 1.6 to see how far i could take the fsb and got the cpu upto 2800 12x233 but as i started a 1m superpi it crashed. I tried to restart but the mobo is dead. tested with p4 and same wont start no post at all. tested bios chip ok.
just hope ct-479 and m730 are ok.

Well, I went ahead and bought the 730ES, so we'll see if it's any different compared to retail.
My current Dothan rig:

P4C800E-Dlx (1021BIOS)
CT-479
730ES

Ummmm.... On a cold boot I get 1.35vcore, but a warm boot gives me 1.6vcore. There's no where to change the vcore, and Im using a p4p800se with 1008 bios. Is this normal?
05-25-2005, 01:36 PM
Astral7

Have you tried 1009se01?
05-25-2005, 01:51 PM
Lithan

Not yet, I'll try it if I can't get this thing working.

So far I reboot/lock at anything above 170FSB. Seem stable at 169 though. Here's the really wierd part... ONE time I had this thing up close to 2.8ghz and prime was running fine (ran over 15 minutes at 2750+) but CPU-z wouldn't launch, so I rebooted and since then I haven't been able to break 170x15 again.
05-25-2005, 03:17 PM
Lithan

1009 now. Voltage works right, but I was under the impression Dothans could be underclocked via the multiplier. Mine says it's locked.
05-25-2005, 03:44 PM
Lithan

Still stuck at 15x170 (2550). Any more and system locks or reboots. Cpu is at 1.5v and can go lower, so Im not maxing it out in mhz. So I assume I've hit the 400fsb Dothan FSB wall. I need to know if anyone knows a mod or workaround or bios setting I can change to get higher.

p4gd1 is pci-e. Hard to find if you are in the US.

On another note, I got my 730 to run at 2690 for few superpi 1 meg runs. Still, pretty lame for 1.6volts and a 7000alcu heatsink.
05-25-2005, 10:41 PM

I did the U-wire mod, thx for the hints :D . Vcore is now locked on ~1.55v. I cannot lower it. :( The BIOS doesn't show any Vcore option. EIST and CPUMR still show the same voltage range 0.988-1.356 but don't work for the vcore adjustments anymore. I am kinda worried because the crappy stock HSF keeps the temp in the 55+ range. This after that I replaced the original thermal paste with arctic silver and got a ~10C improvement Is a 1.5+V vcore safe for 24/7 use? Any suggestion on how to lower the vcore to something like 1.4v?

Anyway, the Dothan is cool. So fragile and light but also freaking powerful. I improved my own SuperPi record. Close to break 24 sec with OCZ EB 1:1 3228 3.2v In the meanwhile I completely :banana::banana::banana::banana:ed up my awesome 9800 pro and I got a x700pro as temporary replacement. I will do some 3D testing later this week.

Damn nice piece you got there man, mine does 150 MHz less with stock cooler and 1,55V. :( There isn't any danger running it at 55-60°C. :)

Just pull it off. It's not attached any way except fitting snugly on the pinns unless Im mistaken. I ripped the Plastic floppy molex connectors off dozens of 9700/9800 cards.

Damn. A 730 would have been perfect too. 12 is just the multi I need. Wish I had done more research before I bought. My 1.5 is pretty good (Priming at 2.5ghz 1.39vcore now), but I know I could hit 2.7ghz+ if it wasn't for this 170-200 problem.

Hey Guys,
I set up my Dothan Rig:

P-M 730 U-Wire Mod => 1,55V
Asus P4C800-E + CT479
512MB Twinmos BH5

I cannot go anything above 2350MHz stable with it, can this be?
I can't imagine that 2350 is all, a dothan can do?!

bro easy to know, try at lower v-core, if you can reach same frequency isn't the cpu :)

So, with 1.25V-1.3V I can go @ 2250MHz stable..I'm really frustrated...Does anybody know something?

I'll assume you are scaling the FSB via Windows. I've found I can go higher with Clockgen if I don't jump the FSB all at once, creep up the clocks in 2 or 3 steps. If I go 2000-to-2700 in one step, freeze. But if I go 2000-2400-2700 it usually works.

2x512 will run ok at 255mhz 3.3v
2x512 and 2x256 is very unstable at all speeds i tried i dont know that 4x512 would run

I used the retention clips that followed the adapter, but it's something I wouldn't recommand. It's a tight fit and I chipped a bit of my core, but it's still working. Also cut a bit of the opposite corners of the housing of the avaperator to make the using of the retention clips possible. :fact: <- Bit scary looking he is. :p:

It sucks because from my experience if the cpu is under load 24/7 (i.e folding). 1.55v can't be handled by the stock HSF. Temps fly in the +60C range. :shocked: So until I develop a better cooling solution, I would rather lower the vcore to something like 1.45v and let it run at ~2.7G.
I like this Dothan and I'm trying to not destroy it too early.

Firefoxx please post your mod results. Thx ;)

Anyone heard of problems with ES 533fsb chips??
My 730ES acts like a 400fsb part. I am on P4C800E-Dlx and 1021.
At 165fsb, no matter the multi it will lock. I have Vcore @ 1.53, can't boot at 200 and can't OC there from clockgen, either.
Tried 400/533fsb JUMPER on ct-479, noticed NO difference... always boots at 533.

There is no FSB option in the BIOS, with CPUCool I can get 120 MHz 3:4 @ 1/3 PCI divider but 120 1/4 freezes. The board ignores the FSB jumpers @ CT-479. With a P4 2.66 160 MHz 1:1 (SD-RAM... :stick: ) were stable.

That's boring. :(

Tested my Pentium M 730 on a friends Asus P4S800-MX, it bootet. I will try to install Windows and se how it does. :D

Didn't want to boot Windows XP nor the Windows XP installation, but Slackware Linux booted just fine. :confused:

Edit: Slackware runs like hell, but the motherboard only boots with 6x MP with the Pentium M 730. Threw my Celeron M 350 in who's locked with 13x MP and running 13x180MHz just fine. :) The board is using the Award BIOS.

i have a p4c800 dlx flashed to 1021.003. When i adjust the FSB with clockgen my agp/pci speeds move and don't appear to be locked. Is this an error or do I have a problem? Also i have a dothan 725(400fsb) and I set the jumper to 533...my multiplier seems to be locked at 12 even if i try to change it in the bios. Is there anyway to be sure that my agp/pci is locked?

It's the same on a p4p800 with bios 1021.003 if you set fsb to 133 and enable memory turbo the pci/agp lock does not work. I used the p4p800-e bios 1007.003 and this worked ok and i am told it will work on the p4c800 too.
Plus with the p4p800-e bios you can change the vcore.

If you boot at FSB 201Mhz, the AGP/PCI will stay locked.

Is there any way to lock the AGP/PCI when you use clockgen if you don't boot at fsb 200 ?

Well I bought a P-M 750... to replace the B0 730...
Only question IS.... will I be able to boot @ 14 x 201=2814mhz @ 1.5v on AIR?? Obviously it'll be fine on phase change, but hopefully I can play with it on AIR, too.

there are some "tricks" of the trade, too :D
One thing that can be done is to take a piece of DI and sit it on the heatsink for 5 or 10 minutes before boot... or freezing spray...

I'm pretty sure I have a 725 but cpuz says i have a 730 and i'm locked at the multiplier 12...how can i be sure which it is?

I think it's possible but for sure not with the standard heatsink. My Dothan is running 24/7 at 2.7G 1.5V temp 55-65C range. I ordered an XP-90, I hope to hit 2.8G stable with that.

I'll write down the numbers tommorow...I can't take a pic cuz i don't have my camera with me. Its strange...the mutipliers 12-28 can be selected but only 12 works (it can't go up or down). Also when ever I open my bios the 28 multiplier is always selected but boots up as 12?? My cpu can do 158~159 max fsb so I can't really overclock it too far. Could it be a bug in the 1021d.003 bios that won't let me select a 16 multiplier?

Going from stock heatsink to zalman 7000 only gave me an extra 40-50 stable mhz at 1.6 volts. You may get better results though....you seem to have a much better cpu.

What are your temps?

The maximum temp I've seen is 40 C....during a superpi 1 meg run at 2690mhz and 1.6volts. Might have gotten a little hotter if it was loaded for a longer period. Used a panasonic 69cfm 92mm fan. Also, forgot to mention, that is the alcu version of the 7000.

does it matter if its a 478 pin dothan or a 479 pin?
Just now i got an offer for a 478 pin, 533mhz C0 stepping Pentium M 750, but the drawback is of course that it is a 478 pin PPPGA socket processor.. Would this matter? I have used Banias processors earlier both on Aopen 855 motherboard, and on a CT 479 adapter, but havent done any overclocking on them...

Could someone please help me?

With hatemi moded machII, Dothan 730 with asus p4p800 e dlx 3Ghz.
Only 200mhz more than with air :(

Dothans are 478 pin, they just call them 479 to differentiate from 478 desktop chips. Despite the same # of pins, the layout is of course different.

This is the overclocking thread; see this thread for general Dothan questions.

These Dothans seem to hit a wall at a certain point. Still, its surprising that you didn't get more than 200mhz using youe mach II.

Anyone able to link me to any benchmarks of Overclocked Dothans vs overclocked A64's in Call of Duty? I was going to do my own benching, but Im getting sick of waiting for my A64 boards to get back and need to decide now which rig will be my main one.

This is the only one I found, and its benched on the AOpen i855GMEm-LFS which aint performing on line with ASUS cards :rolleyes:
Clocks:
P-M 755 @ 2.0GHz and 400MHz bus
P-M 755 @ 2.4GHz and 600MHz bus

So looks like clock for clock the Dothan will be slightly faster, but if my a64 clocks 150+mhz more, then it'd probably be the best choice.

Dothan was going to be a no brainer, but it looks like I've got my hands on possibly the best stepping venice available right now. But I've also got a 730 and a SLK948u coming, so I won't know for sure for a week or two which will be my main rig... though I suspect the A64 will be main and the dothan will be my micro-case/silent server/secondary.
