the 2mm come while the dothan dont have a heatspreader. the p4 has a heatspreader. sorry for my bad english.

Worst case is you get no contact. The only one that I know will work is the Intel retail HSF.
There may well be others - I think one of the SLKs may work - but I only have experience with the Intel HSF.
DFI's motherboard is officially out.

Does the problem with the OCZ Booster also occurs in the latest/retail versions? :confused:Quote:
DFI ® Brings Dothan to Performance Desktop Computing

DFI ® Brings Dothan to Performance Desktop Computing
- The new Pentium M based 855GME-MGF “green motherboard” aims at energy-conscious enthusiasts who demand the best cool and quiet platform for overclocking or underclocking --
DFI, maker of the award-winning LANParty™ and record-scoring LANPartyUT series of motherboards, today launched industry's most enthusiasts-oriented desktop Pentium M motherboard, 855GME-MGF. Based on the Intel mobile 855GME/6300 ESB chipset and supports socket 479 Pentium M processors, this motherboard merges cutting edge mobile technology and performance potentials onto an environmentally friendly platform. Its low heat generation, virtually fan less operation and performance-oriented design makes the new 855GME-MGF the perfect solution for small home servers, silent home theater PCs, or blazing fast gaming systems.
Designed with versatility in mind, the 855GME-MGF is based on the standard micro ATX form factor and features support for low latency DDR333 memory and AGP 4X. Similar to the CPU socket used in notebooks, the motherboard features a low profile CPU socket that fully supports socket 479 Pentium M and Celeron M processors with 0.09 µm Dothan or 0.13 µm Banias core. Migrating the mobile chipset and CPU platform to the desktop means DFI users can now truly enjoy green computing without the expense of performance degradation. From lowered energy consumption, low heat generation, low noise generation to a possible fan-less system design, the 855GME-MGF motherboard promises more than any current desktop can deliver.
In addition to the green features of this motherboard, DFI's 855GME-MGF also brings performance desktop computing to a new height. “In general application performance, a 2GHz Pentium M actually outperformed the desktop chips and even in gaming and workstation applications the Pentium M was competitive, all while running at significantly lower temperatures with much lower power requirements.” said Anand Lal Shimpi, Editor-in-Chief of Anandtech.
To equip overclockers with the best platform to work with, DFI's new Pentium M desktop motherboard boasts a robust BIOS that is packed with optimization options at the widest ranges. Advanced BIOS features include adjustable CPU clock (100 to 250 MHz), adjustable CPU ratio (6 to infinite), adjustable FSB to memory ratio (1:1, 4:3, 5:3), asynchronized PCI/AGP modes (33/66, 36/73, 40/80), and built in stability testing for both memory and CPU. In intensive gaming, DFI's new 855GME-MGF with an overclocked 2.8 GHz Pentium M processor flies past competing platforms with ease. Compared to the performance of Athlon64 4000+ and Pentium 4 3.4 GHz Extreme Edition in Doom3, DFI's new solution tops the chart with a large margin lead (see chart).
http://www.dfi.com.tw/Upload/News/US...s/arch333a.jpg
The DFI 855GME-MGF will start shipping in North America through DFI's authorized distributors and resellers starting November 8, 2004. Each motherboard is bundled with a specially designed heatsink/fan to ensure highest compatibility.

bump for new toys :D
Just waiting for the DFI to come into the retail channel...
@ all can any body test the aopen bord with booster in the first slot is it there running to?
my ram has cooler and when i put the ram into the same slot as kyosen i cant put any booster or ram in the other. so i must put the booster into the first slot near cpu. but is that runing? can anybody test that? my bord and my 1.7gigg dothan comes friday.
Greets Dennis
It looks like the Booster needs to be trimmed or re-sinked cause that little extra piece of heatsink of the mosfets blocks a CAP if you try to put it in the 2nd DIMM slot...if you put it in the 1st DIMM slot it block part of DIMM slot 2 area....I think best option is to trim down the heatsink on the booster and put it in 2nd DIMM slot...gonna do that this weekend..Quote:

Well if it is BGA isn't it very possible that there is no contact being made between the socket & the ball grid?Quote:

Now i am not at home but tomorrow i give it a try.
P.S. but are we all sure that socket was universal?
EDIT: is your 1.6@2.3 dothan at default vcore?
EDIT2: unfortunately it is a no go. Only a dream. BGA dothan on aopen does not work. :/ aopen manual is at this point a little weird. :/

nice chip the 725. :)Quote:

kiko it give a adpapter for bga dothan. on pga sockets.
i did not think that it needed an adapter. I have no adapter. But adapter is not sufficient coz you have to knit (i do not know if is right in english in italian is "saldare") it to the socket.Quote:

Good find charlie. Hopefully it'll reach some other retailers and drop a bit...
Hopefully i'll get my DFI today...at least it was sent out to me yesterday.
Darn, i wish i hadn't promised my gilfriend to go snowboarding this weekend so i only have a few hours to put the sys together and run some benches. :(

You've got quite a nice one yourself, Siphilon.. Hows the temps? :)
Temps are fine for the stocker cooler. 38-43c. I'm going to try a better manufactured hsf setup early next week and then play with the vcore. If I can get 2.5 stable on air out of this chip I'll be really happy...and I think it may be possible (the sky is the limit of course...no need to stop until the chip stops me!! :banana: )Quote:

Here are my new results of i855GMEm-LFS over-clocking.
Now nearly 1.7V is available for Vcore.
I could run the system at over 2.9G by natural air-cooling(17degree centigrade).

Extreme , that is a insane score man .
Congratulations for the 23s .
I´m amazed with the power that 3318 pentium m showed .
Guys with te fx55 ´s fear this man .
Don´t let in get an good vga card .
Congratulations once more
Kyosen, that is an explosive result man :explode:
Congrats!! :worship:
\o_ , nice :)
awful lot resistors u have removed :o
but i think the chip needs more voltage :D
holy cow thats fast.. Do I smell a WR comming up ? :D
superb job there k-ohashi
wow very nice thats the right way. ;-)
That's magnificent, Kyosen! You are truly extreme! :)
If some manufacturer would open up their eyes and release board with some serious voltage adjustments!
Maybe a stupid question, but is any P4 cooler socket compatible? I read that it was the same bracket. :)
Wonderful overclocks from TAM and kyosen. :slobber:
Congratulations for both. :toast:
That two SuperPi's are amazing, 23 and 26 sec are just spectacular times.
We want to see more and more results, precisely a 3dmark score is possible.
I know that with LN2 that is very difficult but just go for it. :)
Again, more congratulations for you both. :toast:
Intel (at last) has a major response for AMD's FX in the Dothan's(Alviso,etc...) :banana:
:eek: :eek: :eek: That is the definition of extreme !!! OMG Kyosen keep up the good work !!!
I just have one question, dont the mobos you guys are using have PCI/AGP locks. Cause I imagine your overclocking + XT PE would ROCK THE ORB !!!
Though I imagine even the ordinary Dothan desktop system (with i855 mobo and 745 proc) would cost WAY too much for the normal consumer, unlike a mobile 2500 or something.

For some reasons, ATI (or its driver) is not working all that well at AGP 4x with AOpen board. I got 23,465 points of 3DMark2001 with both 755 and X800 XT PE were stock. Check here: http://service.futuremark.com/compare?2k1=8228933. Plus, I got random Windows boot problem where my system will be stuck at Windows splash screen forever especially after a failed overclocking. I have tried several versions of ATI Catalyst. nVidia is working flawessly though.
Do you have more detailed pictures of the vcore mod?
Is there a other simpler mod available?
IS a vdimm mod available?
Hey, kyosen!
Is there any trick to get the fsb that high? :confused:
I'm stuck with my DFI at 145Mhz. :(
Already did some voltmods
- vagp/chipset to 1.7V
- vddr to 2.9V
- VID4-Pinmod for 1.6Vcore
...still no success in gettig it any higher.
Even at 1:1 with my Infineon PC2700 6-A ram which is good for FSB220+ at fastest timings there's no go -> errors out in SuperPi (test 5) or sudden reset in Windows.
This happens no matter what multi i have set in bios.
12*145 crashes as well as 17*145. :bsod: :bsod: :bsod:
Hi,
Mathias-K,
> is any P4 cooler socket compatible?
--
2mm or so thickness metal plate must be inserted
between P4 cooler and core.

I expect that you are using Radeon, don't you?
As H2OGun mentioned it, nVIDIA's VGA is more robust
than ATI's at i855GME mb, I also think so.
In my worst case, the system goes unstable at mere 135MHz
with Radeon9200 VGA.
...Try GeForce ;)
Kyosen does have a simpler mod. Check out his BBS mentioned in his previous posting and you'll see some mod pictures. I've tried it myself and it only gave me around 1.45v vCore max.Quote:

Kyosen, would u like to have an utility which detects if the throttling is activated or not?
COPYRIGHT Franck Delattre
send me a MP if u r ok
kyosen or anyother with the AOpen board,
Could you answer a few questions regarding the AOpen i855 board?
Whats the easiest way to get 1.7v of vcore? Also can I use a S478 waterblock on the AOpen board?
Is it possible to connect the vdimm directly to the psu's 3.3v rail?
Hope you have the time to answer my questions. :)
I think the easiest way to adjust vcore is to perform the modification pictured a couple posts above...by Kyosen. You can use a s478 wb but you've got to be very careful because it's pretty easy to chip the core. My solution was to use a heatspreader from a s478 chip and put it over the P-M core.Quote:

I've tried with timings all the way to 1:1 as well..with a 1.6G & a 1.7G. Same result...On occasion I can get into windows above 145 but it either freezes, usually right after arriving into Windows.
and although I havent tried using the booster on the DFI, I tried in on the AOpen w/o any success ;-/

Dang, I still havent gotten over than one Kyosen !!! WOW !!!!
Though, when are you gonna post some 3dmark01 or pcmark or anything at stable speeds or is it not possible with the dothan, cause with the result above, you're making an FX-55 look bad !! :D
Perkam
Hi,
I am very impressed about the results. 3,3 ghz is really a nice clock for a Dothan Core.
I'm going to overclock a Pentium M 745 (1,8) processor with a combo of TEC (maybe 2 cascades) module and the Thermalright XP-120 cooler. V-Core Mod is no problem (i will use the VID4 Mod), but i cannot find detailed pictures and tutorials about VDDR and VIO chipset voltage mods for the AOpen Board.
Can anybody post some detailed pictures from VDDR and chipset voltage mods on this board?
Thanks alot,
BitpowerPM
When you do, pls report back results !!!!! And if you get it to bench with an X800 or ANYTHING, you'll be one of the first ppl to do it. Have Fun.Quote:
