OK guys.....got a weird thing going on here.
Have some kind of limit at 142mhz FSB...100% stable @ 140...superPI @ 142...no boot @ 143 an I got a loooooonb beep.
Tried to lower the multis...but still the same. I know it´s not my memory because they do 280ish @ decent timings and a tad below 300 with crappy timings, so that shouldn´t be the problem....also tried running singel stick but nogo. Tried different agp/pci locks but still the same.
Mabye an agp/chiset modd in order..?!?!? :confused: :confused:
That sounds like a memory error.
Are you trying to run cas 2,5 ? If so you need to use the 105 bios, cas 2,5 won't work on earlier bioses.
Hvis du fremdeles er online kan du stikke innom kanalen vår ;)
That points to how the clock gen has been programmed....I will have the DFI guys have a look over here at what we are doing and see if they can help.Quote:

I am running 1.05 bios....first thing I did before installing OS was to flash latest bios. Haven´t tried to run cas2...tbh I haven´t even thought about it since it didn´t like cas2 in my winchester rigg....toped out at about 220 with cas2.Quote:

But AGAIN, I can confirm that at lower speeds, the difference in sPi between like 200mHz mem speed and 240 is like 2 seconds!!! These things are ABSOLUTELY bandwidth-starved!

try 88/44 :DQuote:

the higher you go the higher AGP/PCI you need (w/ the DFI that is..).
Have no idea wtf is going on with this....tried some memtest86+ v.115.
My mems wont do much above 230 with cas2...so I ran it with 2,5.
140/234 is OK....runs thru all tests and test5 multiple times...but when I set it to 141/235 it freezes instantly at test5.
Memory I´m running is Adata DDR600.
why would you bother locking the pci/agp clocks at those speeds? especially if the agp really doesn't lock at all.Quote:

AGP not locking at all? Really? you mean w/ DFI or with AOpen or w/ both?
with the DFI, I believe it was bigtoe who said that or at least he leaned towards that conclusion.
Definiatly with the dfi. :(
Just to clarify.
The PCI lock on the DFI works bang on..set 33 and it stays at 33.
AGP lock im not so sure about.
Max fsb 1:1 for me was 190, max fsb async was 170.
I can run 3:4 low graphics at 150/200 all day at 16x150 1.26V for a super quiet server but it has the odd issue with my ATI cards if I go AGP..setting a higher lock value helped.
Hope this helps you guys
OK guys....have been fiddeling around with abit more...mobo is still unmodded...everything is as it comes in the package.
Higest 3D stable fsb...won´t post any 3dmk shoot because I´m running ati9250 atm...and it would just be embaressing...
http://upl.silentwhisper.net/uplfold...han_170fsb.jpg
One other odd thing I ran into with this Aopen mobo ....as I reposted before I couldn´t go past 235mhz on memory no matter what I did...really anoying, knowing that those A-Data DDR600 sticks does 280ish in dualchannel on Neo2.
So when fiddeling around with different settings I noticed the timings reported by memtest was not the same as I have set in bios....and reported by Cpu-Z.
In bios I set 2,5-3-3-7 (that is "By SPD" settigs to)...and 3:4 and 160fsb..this gives 213mhz as you can se....but take a look at the timings reported by Memtest and Cpu-Z ......WTF :confused:
Cpu-Z
Memtest
If memtest DOES report the right setting being used by the mobo and cpu-z gets it all wrong.. then this might be the explination to why it won´t go further...as those stick won´t run stable much above 220ish with anything set to 2.
Anyone else noticed anything similiar to this with Apoen mob and TCCD sticks...or any other 855 mobo...???

Is there any theory around the stepping. Higher in the alphabeth means newer stepping? Like on AXP's and Winbond chips? I'm new with Pentium.
Edit:
I found what those codes mean:)
SL7GL = 1.5ghz dothan
SL7EN = 1.8ghz dothan
SL7EM = 2.0ghz dothan
Does your vidcards/whole system get glitches when running high fsb/agp clocks on the Aopen even when usin 37/74 lock? I have been reading some experiences complaining about system laggin´ ...i´m seriously thinking about buying Aopen + 735 set(Already have Rad X800 Pro VIVO@ XT PE +), but the overal smoothiness of the combo on high clocks(fsb >160) makes me wonder if this is worth it?
Anyone got a link to a picture of the Boxed Dothan cooler?
Yes I´m having glitches when using agp/pci lock 88/44...like small laggs in 3dmark...this doesn´t occur when using 75/37 lock....but when running above 155fsb I have tu use 88/44 otherwise it will slowdown the system like crazy.Quote:

A64 Clawhammer @ 2.4GHz (10*240HTT)

Nice WiCKeD, now get that A64 down to 133HTT to show the REAL deal about the Dothan power ;)
Does a Pentium M (dothan) ES exsist?
What are the benefits of an Engineering sample? Cos a dothan is unlocked :). Maybe on an ES you can choose higher multipliers :banana: ?
I've found this picture on eBay, is this for real? Or a hoax? I've never seen a Pentium M chip with resistors on top :banana3:
looks a dang lot like an A64 mobile clawhammer to me.
An A64 Mobile Clawhammer with 'INTEL' written on it? :p:
I think this is a picture of a Dothan without heatspreader.
And I think this is what a Pentium 4 without heatspreader looks like.
And I think this is what a Mobile Athlon 64 Clawhammer looks like.
So I've got no idea what it is... :confused:
BTW I thought a Dothan only has it multiplier unlocked downwards.
Its entirely possible, dont believe everything you read on the internet :stick:Quote:

I benched 3d2k1 and this is the result. Not bad. :)
http://service.futuremark.com/compare?2k1=8334389
Been watching this for a while and the Dothan looks seriously impressive against FX-55s and EEs when overclocked. From what’s been said it seems that bandwidth is the way ahead rather than all out CPU speed.
I was saving up for an A64 system but seeing how this will be cheaper for comparative speed I'm changing my plans but have a few questions before going mad with the money!
Memory
Seeing how FSB is more important I'm assuming that TCCx based memory is the smart move. Both due to it being widly available on the market and the lower voltage needed to overclock (~2.8-2.9v right?). Is OCZ's XV any good assuming a vdimm mod to the mobo. Also If I was to use an OCZ voltbooster I was intending on running 1GB of RAM, so in this situation I'd need a single 1GB stick. Anyone know of a suitable stick based on TCCx or whatever else is recommended.
Cooling
Though it’s pretty obvious that these things don’t run hot, I was planning on using water cooling (CPU and GPU). I was thinking that the Swiftech MCW50-T would be pretty mint, as a retention frame could be used in the same way as their FX adaptor, just drilled differently for the 4 holes on the DFI board. Perhaps its early days yet to be asking, but is there anything to be gained by using a TEC on these CPU's?
Cheers
JB
Why hasn't anyone here phase changed one of these yet?
Are the mobos too buggy to run at those speeds? :confused:
The Dothans are plenty stable at lower fsb's....
Running at 20 x 133 = 2667mHz, at 200mHz DDR400, 2-2-2-5...it's ROCK-SOLID with a northbridge cooler.... just the mem b/w is a bit low.

If your refering to the DFI, then the head will need some serious mods. The Aopen mobo however has a standard 478 HSF cradle so the Vapo should be compatible. However, the heating pad for the top of the CPU surface prob won't fit and due to the lower profile of the CPU the head may need to be screwed down more. I'm not totally firmiliar with the retension mech. for the vapo but I think you can get away with it. Anyone willing to give it a try?
Yeah, I just found this review, and it reveals that the DFI's holes are non-478-standard (how dumb is that?).Quote:

In fact, we scanned the web thoroughly and couldn't find any aftermarket Pentium M embedded heat sinks available anywhere. If you are looking for more aggressive cooling, it's more than likely going to require a custom design effort on the part of the enthusiast, at least for now.Why would these DFI tards design the holes non-standard, with the plethora of 478 cooling options out there? Idiots! :rolleyes:
As far as the Aopen goes, I only see 2 small mounting holes around the socket on that board. :confused: The Vapo uses all four 478 mobo holes to secure it to a steel plate on the back, which also holds the heating element.
I'd be happy to give it a try if someone wants to loan me the goods, but no way I am pulling the trigger on this to have my expensive Vapo sit in the closet. :( Man, I would love to throw my Vapo on one of these chips doing 2.8 on air, and run 1.7v through it! :slobber:
uclajd: I have the Aopen board...and I can confirm that it has 4 mounting holes...and it uses P4 standard mounting mech. So both Vapo and Mach II will fit with 478 brackets....however the height of the cpu socket and the cpu it self may or may not be a problem.
But here's the MAGIC about the Dothan....
you don't NEED a HS/F like that!!!!!
A Swiftech MCX159 and a MicroCool NorthPole are good for 2.8++
Customize a s370 hs/f just for fun....
C
The DFI board has standard northbridge holes, which is all is required to cool the dothan really.

I think the numbers are off. If you look at the schematic of the 479, the holes are 41mm x 41mm. Based on measurements I just took on a P4C800, the 478 socket's mounting holes are more like 77mm x 60mm! :eek:Quote:

3 inches = 76.2 mm. 2.34 = 59.4 mm. So my cheap plastic ruler measurements were a little off, but you get the point.
WRT the height of the CPU and socket, no problemo. When you install the Vapo, the evap is supposed to protrude from the foam like 2mm. As you tighten it down, it makes contact with the IHS, and snugs up against it. To some degree, it retreats back into the foam/housing. It really is quite flexible in terms of height. Just let the evap protrude 2.1 mm for the Dothan. ;)
Need? Need? LOL, since when is XS.org about practicality? :ROTF: These pursuits are about conspicuous excess, getting faster, quicker, lower times. If I lived in Antarctica I'd be burying my Vapo's compressor in the permafrost! If I got my processor down to absolute zero, I'd wonder, what if I added a bigger fan on the raddy? (yes I know this would be both impossible and futile).Quote:

^^^^ good Question, Aopen seem to be freely available in the UK but I can't find a single DFI board unless I import :(. I'm currently leaning towards DFI as they usually follow a mobo with good BIOS support whereas most manufacturers only upgrade their BIOS if a problem is found, rather than attach better overclocking options.
macci can you verify one thing on aopen?
On mine i see a weird behaviour.
If you open aopen software inside windows and look at the cpu T you will see the same or higher T that you see inside bios.
Now is it the aopen software that grab its T from bios (weird) or idle is not working properly in your opinion?
My windows driver is uniprocessor ACPI and idle process is in my task manager.
Other weird thing is that bios cpu T starts at 36.5° w/ 20° ambient T and goes up to 41/42° and stops there. Full load or not full load.
Give it look if you can.
P.S. a first Pi look w/o booster. :)

Charlie, I totally understand what your saying, the fact is these CPUS will overclock to ~2.7GHz on air due to their great thermal properties. Perhaps I should reword my question a little. Is there anything feasible to be gained from using watercooling/TECs over air, or is the performance gain minimal when you reach these dizzy heights?
Im from the uk also mate, can u post the links of all the websites that sell the aopen mobo??Quote:

I firmly believe if someone puts out a decent mobo (which neither the DFI or Aopen are, by modern enthusiast standards) that could hit higher FSBs and memory clocks, a phase on these things would be scary. :slobber:
Shigs,
So far I've seen Dabs and Kustom PCs plus according to the overclockers.co.uk forums they should be receiving Aopen boards today and DFI boards by the end of the week (heres hoping!!)
EDIT: just noticed that Overclockers has an Aopen board on their site now, DFI to follow...
Actually anyone know what the thermal rating of a Dothan is when overclocked. I know the TDP rating is ~21Watts but this'll shoot up somewhat when running high clocks. Reason being this is the operating range of the MCW50-T and I'm curiousto see if the TEC needs upgrading or if the 80 Watt one currently installed will suffice?
http://www.swiftnets.com/assets/imag...tingrange2.jpg
Hehe, that thing would keep the biggest Dothan frozen @ stock wattage :)
And then chill the water.... :)
mcw50-t would be awesome!!! It'd probably keep the CPU under 0C even under load...
C
Use this handy online wattage calculator. But first you'll need to visit the processor finder to know the stock values. There is no single answer, as it depends on which chip, what voltage, and how high you overclock it. For example, the 2.0 SL7EM, default voltage at 1.34, stock wattage 21, set at 1.6v running at 3.0 would be under 45 watts. Even at 1.7v, at 3.0 GHz it would be under 51W. To hit over 80W, you'd need to run the 2.0 at 1.7v @ 4750. If you find a 2.0 that will run at 4750 under any conditions, let me know, so I can come over to your house and conk you on the head, take it from you, and pwn every bench known to mankind, SLI or not. :lol:Quote:

I have a MCW50 without the T, and its mounting holes/screws are about 55mm apart, too wide for the 41mm Aopen and way too small for the weird DFI holes. The block itself is larger than 41mm, so it would be very hard to mount on the Aopen (80-172W peltiers themselves are 40mm X 40mm). DFI could be done, but you'd likely need to fabricate a bar or star bracket to attach on the back of the mobo. Not hard for some of the McGivers here, but know what your are facing.
I don't want to poo-poo this idea. Frankly, I love it. I'd buy a DFI and Vapo it if I could fab a evaporator housing (I actually use my PC, on my desk, in a pretty case, so I don't want to do the messy foam-and-clamp in the garage method). But even if I could make it work, these boards really do suck (even the almighty FUGGER tried phase change, and it was like perfume on a pig with these boards).
If a good board comes out for this thing, I'll be on it like a pit bull on a poodle, and make the Vapo work. And for those of you who think I don't need a Vapo, I already have one, and they are very expensive paperweights.
Hmmm..... are you sure the DFI pattern is too small? I use a standard Swiftech NB cooler on mine and that's the same size as ATI pattern, isn't it?Quote:

I've got a Dothan and the DFI 855GME, but I'd rather not remove the resistor for more Vcore, since it's a test board and will eventually go back to DFI.
I can't seem to find a link to the wire trick anywhere, my searching skills on the forum and Google are weak today!
Need more Vcore to push past 2.4GHz with my 1.7 :D

Charlie, you sold the DFI?!?, what was the problem, was it too flaky?
Non working agp lock I guess. Go for the aopen anyway.
what on offer from the Aopen that the DFI doesnt, apart from the socket mounts. Isn't the DFI capable of 533MHz as opposed to the 400MHz of the Aopen?
There are some issues when you go past 133 FSB and have an Ati card, it freaks a bit out. We think the AGP Lock on the DFI board is not working.
About the agp lock on Aopen...I don´t know if it´s only mine or if anyome else experienced same thing.
All 3 agp/pci lock options work up to certain levels of FSB....it doesn´t work completly. I.E ....when I set 66/33 I can go up to about 140fsb...with 75/37 it craps out at about 156..and finnaly with 88/44 it allows me to go up to about 170, but when running an ATI 9250 with the 88mhz lock I get stutters/lagging when running 3DMark wheras it dosen´t when locking at 75mhz.
Fair enough, might take a step back til these bugs are fixed, whats the general consensus , can this be fixed via a BIOS update or is a more direct motherboard revision required? I take it these problems havent been detected with the Aopen boards,altho I suppose they cannot reach these speeds anyhow :(
Hmm, I did the v.mod as linked (cheers!) but I haven't been able to push much past what I could before. I'm using an ATI 9800XT. I'll throw in a GeForce....
OK, my bad, it's the DFI that is weird. I got them mixed up. Will be quiet now.Quote:

Mounting bracket yes. P4 heatsink no. No because the dothan core is some 2mm lower than the top of a P4 heatspreader. So you can indeed put a P4 heatsink there but its possible that it wont make good contact with the dothan core.Quote:
You are telling me that a standard P4 heatsink and mounting bracket fits the Aopen?
Yeah, so you need a P4 HS/F that uses spring clips like the Zalman or even the Hyper6.... the ones that use levers and such won't hold well. You could even bend the clips a bit to exert more pressure :DQuote:

Hi guys,
Can I ask you guys a couple of questions?
I have bought a Aopen 855 GME board, with a Pentium-M CPU, and I'm having trouble getting it working.
First thing, I have installed the CPU onto the motherboard, following the instruction in the manual. Turn screw anti-clockwise, insert CPU, turn screw clockwise...is there any way the CPU can be seated incorrectly?
I installed the HS, connected the CPU fan and system board fan, plugged 2 sticks of 512MB RAM (2700).
Plugged in the two power connectors, KB, mouse and monitor.
Switched it on. The Stby-LED does not come on, nor does the bios LED. There's a third LED on the board, 'LED2' stays lit up.
When I power up, the KB's LED flash once, but I get no signal going to the monitor.
Any idea? Is my motherboard faulty?

Before I do that, I will try re-seating the CPU and see. I'll probably do that tomorrow though, getting tired :D
Guys...need a confirmation on this vcore modd on the Aopen board...if anyone done it here..?!?!
Does the resistor in the modd need to be removed or is it ok to just solder the cable next to it...?!?!?
If I´m not mistaken...it sure loks like KYOSEN has removed the resistor completly.

I have done the Vid4 modd already...but my board is acting weird....everytime I reboot, either after saving in bios or "rebooting" from windows my system halst upon reboot and I get a series of beeps.
I then have to shut down my system completly and then turn it on again.
Other than that the modd works perfectly...!!
I tried to redo the viretrick but it´s still the same...very anoying. :( :(
Does anybody else get this with the wiremod, as i was thinking of doing it myself?Quote:

Whiremod running here, no problems.
what is the SSE2 patch and what does it do? where can i get it? looking to give my m755 laptop a run for its money and see if it can't go any faster
with the sse2-patch super-pi will run faster on cpus which have sse2. its like the prescott-patch for the prescotts!Quote:

Yeah, i pushed up my Centrino Notebooks SO-DIMM DDR333 from 2,5-3-3-7 up to 1,5-2-2-5. :D

Centrino really rulez !!
cu, BitpowerPM
....SO many opinions....
I understand that if I buy 1.7 GHz Centrino, the usefull overclock would be not more than 140 FSB on both boards. Because of AGP. 17x140 gives me only2380MHz!!!
As I understood on both boards lock PCI/AGP doesn`t work over 140 FSB. Is it save in using for 24/7??
they called dothan or banias. centrino is something else (notebook with chipset & cpu & wlan modul from intel)Quote:

of course I am asking about DOTHANQuote:

To your question werther it is safe to run the agp "overclocked" for 24/7...I would say YES it is...aslong as it can take it...you have to look for the signs when running 3D... i.e small laggs, stuttering and/or other misscalculations. Aslong as your 3D runs fine and smooth I don´t see any problem.
Generally speaking, nvidia cards will take higher agp clocks than ATI cards....atleas on previous ones. I´m not sure how the 66xx / 68xx series is responding to agp clocks.
Mabye someone else care to answer the question...as I´m curious about that my self...!?!?!?
Thanks a lot Naughtyboy... Now I am quite sure that it`s better to buy A-open than DFI.
I have one more question. Which memory should I use??? Now I have Hynix d-43 DDR2x256 should I change them for a good overclocking?
I will certainly do mods... SO how high FSB can I expect with A-open board? Has anyone checked how important timings are? The best dividers I`ll find in the tests of course ...
