How about a 735, in stock at overclockers.co.uk

They are 400fsb so it would be 100x17 stock ?

I would be happy @ 2400MHz tbh for everyday things and gaming, it would be a nice setup.

Whats the lowest multi that can be used?

And did you just solder between the fsb jumpers?

Thanks! :)

Yes, I did solder between the FSB jumpers, but you can try to run without jumpers befor you solder. :)

Solder it with wires outside from the ct-479, then you can still use a big heatsink

From the standpoint of another cap couldn't hurt, or for a specific reason?

I also soldered a molex to my ct-479. I'm gonna try and keep the fsb jumpers changeable by clipping the pins a little and keeping em low profile.

CT-479 from kustompcs.co.uk

Cheapest 1.6 533fsb dothan i could find from Ebuyer.com

P4p800-e / p4p800-se and any of the p4c boards are all good options.

Whats the best dothan to buy for air use and maybe some DI action in the future but air 24/7? A 1.6 dothan?

The P4C800-E dlx the best board to work with?

Where can I get an adapter from?

Thanks :)

No problem, ebuyer is 100% but i never used kustompcs before should be ok from what other peeps have said.
I will be ordering both soon too.

On my best 1:1 with same tweaker settings as my above posted runs, I scored 22.34 1mpi at 263.84x13(3419) 5-2-2-2, tras 70, rms 7.8, and dram lat par 00.

So 310.4x11 with 5/4 divider verse 263.83x13 with 1:1 divider was about 1/10 second faster for 1:1. I'm sure from your 3d benching :toast: , you see a bigger margin though.

I think it's a pretty close tradeoff between fsb speed / ram speed paired with cpu ghz.

Did not make a difference for me between -145c and -180c .That chip just didnt want to go any faster. I was able to match my scores again last night using only -145c. If my system crashed during runs below -150c, I had to wait for the temps to rise back to 150c before the pc could reboot and the resum benching again. Very weird.

:woot:
I have some questions:
-How did you reached such high fsb :slobber:?
I assume you must have boot below 200fsb? Cos you have P-M 760 (MP15).
Still wanna know how :D :eek:
-With what bios did you flashed your P4P800SE to get the 5/4 divider? P4P800 (dlx) bios 1021.003?

With 760 pent m, The default multi is 15x.....and cannot be changed in bios.
The chip can only do around 2.7ghz on the ct-479 aluminum cooler max.

232 is the limit on my boards(p4c and p4p), IF I BOOT AT ANYTHING LOWER THAN 200FSB FROM BIOS. It is impossible for me to boot at 200x15(3ghz) on default cooler. When testing with the default alum cooler on, I boot the chip at 166x15, then up to 232fsb is available in windows using software along with 6-15 multi's. TO get over 232 in windows with a pent 760, you need to put cold on the chip so you can boot at 200x15 from bios. Once you do that, the sky is the limit on fsb.......well really the max your board will allow ;) Try to find the beta bios 1009 for the p4p800se. Works very well.

I'm currently on the 1009 beta bios :D
But you mentioned you had a 5/4 divider. I can only see 1/1 and 3/4 as available dividers in the bios :(
With what kinda HS you've replaced the stock HS? I suppose you're not cooling it with LN2 all the time :D

guys then if i don't boot at 200mhz i cannot pass 230fsb or so???

sky

that's what he said, for his board anyway. other boards might be able to reach slightly higher than 232 or slightly less when booted at fsb's lower than 200.

once you made it into windows with fsb >=200 you can do pretty much what you want, chaning the multi and fsb via clockgen and eist or whatever tool you prefer. you can even use those tools in an autostart kinda config and make those changes happen on bootup, so you don't have to bother doing it by hand every time - if your sys is stable at whatever you chose to have anyway :D

What sky said EXACTLY....
When on ln2, dI, or even reular phase change, it is possible to boot at 200x15(the multi your stuck with for 760) and then the fsb is opened up.
The 760 pent m is really not the ideal chip for everday air use because of this. The 730 like macci has or 740 possibly are better choices until asus releases a bios that unlocks the multi's from within bios.
When not on DI or ln2, I boot at 166x15(2489). Then once in windows, I set multi to 13 and set fsb to 200 for 2.6ghz. My 760 is very stable at 2.6ghz with using just the ct-479 aluminum cooler and def vcore.

Guys , what waterblock is possible to use with ct-479? May be Maze4?

i have ordered a 740, than a boot at 200 seem possible...

watercooling on these chips is unnecessary

:) so my bad , i was thinking , that watter always help :)
Anyway is there something like better steping or something like that? I just got mine set up , but i gonna have to build the PC tomorow after work...

Revision C0 is the way to go, but how big performance difference can I expect in games between a 1 MB CM and a 2 MB PM running at the same speed? I've checked for tests but couldn't find any.
Does somebody know what the other two FSB jumper combinations would do on a CT-479?

While I was reading GamePC's review of AOpen i915GMm-HFS I saw this:

Quote:

AOpen will be releasing a full-sized Pentium-M desktop motherboard based on the Intel 915G (not 915GM) chipset in the coming months which will boost the amount of DDR2 slots and SATA ports available. While the full-sized board will be better for gamers and desktop users with a lot of expansion cards and peripherals, the Micro-ATX board suits us just fine for the time being.

:toast:
Do you know about other PM mobos on the way?

915 always suck...

Well, I managed to get a Asus CT-479 and a Pentium M 730 to put in my P4C800-E Deluxe that was gathering dust.

So far I've managed 2.66Ghz with the stock cooler.

http://home20.inet.tele.dk/pressure/Dothan2666.jpg

That gave me a 3DMark2001SE score of 32790 Marks.

Not bad for a stock X800XTPE (520/560Mhz)

Great results you got there Pressure. What's the max 24/7 100% stable clock for that chip with stock cooler?
05-23-2005, 06:21 PM
NoX

Right out of the box that's what I get:

http://img50.echo.cx/img50/6933/7301fg.jpg

http://valid.x86-secret.com/show_oc?id=19401

If I boot at 200FSB and then overclock with Clockgen, the PC800 runs with the Performance Mode ON but I lose the AGP lock (ATI issue). SuperPi 1M at ~2.6Ghz is 29sec. If FSB>200Mhz in BIOS, the AGP stays locked even if I use Clockgen but the Perf Mode is OFF and SuperPi at 2.6Ghz is 30sec.
