k-ohashi Pentium-M LN2 is cooling25 second, ID3.3G

[Learn]

Hello, I'm k-ohashi as known as kyosen
Thanks for your interest to my OC result!
...and thanks especially to sxs112 for beginning new threads

> another interesting note - it seems that pci/agp lock is missing? :o
--
AGP/PCI lock is available on AOpen i855GMEm-LFS!
I simply want AGP clock for 3DMark etc. and also want to show
robustness for higher AGP/PCI clock of this motherboard

I'll try LN2 cooling again...in FSB/mem=3:5mode.

good luck kyosen
24s 23s?

kyosen,

Amazing results there.

How far do you think these chips goes on water?

I would also like to know, if you could get the RAM up with 3:5 or if 230-240MHz is the board's max.

Thanks

Yes, this board has AGP/PCI clock option in its BIOS,
which is selectable from 66/33, 75.43/37.72, 88.00/44.00,
and we have to set 75.43/37.72 or 88.00/44.00 for fixing AGP/PCI clock.
If we choose 66/33 setting, it behaves synchronous in case of using
AOpen's clock-mod soft.
Now Mr. abo's SetFSB is also available for modding clock

Kyosen, for what reasons did you choose the AOpen board over the DFI board? Was the DFI board not available?

Hmm, I've not tried Dothan water cooling, but I expect that
there is no significant difference of max clock between air and water.
From my friends, I've heard that PenM725 goes over 2.6G,
and PenM765 goes over 2.7G. Both by air cooling and with Vcore-mod.

My A-Data BH-5 256MB@near 3.6V(by DDR-Booster) goes over 260MHz
Screen shot is here:

And also BH-5 512MB goes upto 258MB(no screen shot).

Here in Akihabara/Japan, DFI PenM boards are not yet available broadly.
Only a few pre-production/sample boards were shipped last week,
and they say that formal shipping starts from mid of this month.


I'll borrow my friend's XT-PE for 3DMark2001 in a few days

Hi Kyosen

With the Aopen board u can only get 1.45v for the vcore with a mod???
I hope with the DFI and another mb we'll can have 1.5v and more

[caater]

i'm not sure if DFI has voltage options or whatsoever at all.
that 64bit PCI slot (or is it PCI-X?) tells what market they are aiming for.
and DFI board doesn't have standard mounting holes :/

but only time will tell..

it also appears that banias/dothan bus is not compatible with "p4 bus".
it uses lower signalling voltage plus some powersaving features and
has extra signal paths/pins for this.

so it would need big manufacturer to produce non855 board and
apparently it would come with a price :/

[Kanavit]

holy cow, that chip rox! 3.3 ghz dothan is equal to a 4.4ghz P4 probably.

[caater]

for 3dmark scores, i'd say a 2.6 dothan is equal to 2.7ghz fx, 2.8-2.9ghz nonfx and 4.2-4.3g prescott
don't know exactly about EE.. but in 2001se, prescott needs plenty of mhz
to take 3.3g dothan down

holy cow, that chip rox! 3.3 ghz dothan is equal to a 4.4ghz P4 probably.

Thanks kyosen.

Well I guess I'm gonna wait and see how the DFI board performs. But I will get a Dothan that's for sure.

Im sorry but holy crap

http://www.x86-secret.com/pics/cm/dfi855/28sp.png
And i see no mention of using anything but air cooling, they actually used a nb cooler on the mobo since the holes fit perfectly.
The also mention the temp never got above 38C.
And yes, i speak french.

So 25s air cpu, *kicks his p4c* i need to get me one of those.

The dfi review was a beta version

[caater]

hmm, they had 25sec superpi @ 2.8ghz, k-ohashi needed 3.2ghz :o

[Denniscooldelux]

whats that why is that. anybody have a idea?

I have ordered the aopen bord now . in germany by mix comp.
i hope it come in the next weak.

[Learn]

hmm, they had 25sec superpi @ 2.8ghz, k-ohashi needed 3.2ghz :o

i'm surprised me too, no idea, why is so faster?

[cpulloverclock]

The aopen is a bad mb?

[Denniscooldelux]

that differentiated is too large


the aopen has ich4 or not?

the dfi has ich5 i think thats it.

i have no other idea.

can that be the problem?

i am confused

[cpulloverclock]

dont know, I talked with The Mad but.....

[althes]

board looks interesting.

[Denniscooldelux]

which? the dfi or the aopen?

[HawainPanda]

awsome..hmmm considering how cheap the dothans are...

[kyosen]

Yeah, DFI's mb looks pretty good!!!

SuperPI English version is slightly faster than Japanese one on Dothan,
and my OC results is upon FSB/mem=3:4 mode, but anyway, DFI's mb
looks faster than AOpen's one!

I expect that memory interleave is enabled on DFI's mb.
In AOpen mb, SuperPI time is same at any memory configuration,
256MB x1 or 256MB x2 or 512MB x1.

I'll get DFI mb in near future...
...and today I go to purchase PenM765 from now

[Denniscooldelux]

do you plan a max fsb overclock on the aopen? or is 178mhz the max fsb?

[kyosen]

> do you plan a max fsb overclock on the aopen? or is 178mhz the max fsb?
--
I regret to say that FSB 178MHz seems to be almost limit of this mb.
Over 180MHz is difficult...
I don't know DFI's mb case, but I think it is indicating something that
x86-secret shows PenM765ES running at 2.8G=175x16.

But i855GME motherboards are running at single-channel DDR, so,
low FSB clock does not matter, maybe...
For example,
3G=FSB150x20@3:5 -> FSB(QDR)=600MHz, Mem(SingleDDR)=500MHz
3G=FSB176x17@3:4 -> FSB(QDR)=704MHz, Mem(SingleDDR)=470MHz
the former may be slightly faster, I think.
