AOpen mobo, no mods (yet)

my watercooled dothan running at 2.6 3/5(2-2-2-5)
2.6 water

31 secs/air
superpi

Aopen

Nice! Unmodded?

Glad too se that my waterblock will fit.. using the same

Charlie, if you open CPUz first then you can open clockgen. kinda wierd but it works.

Hi, I'm new to the board.

Does one stick of memory perform beter then 2 sticks?

No, no dual-channel

thx, FUGGER!!!

Cracked 30k in 2k1 w/ dothan - not too difficult obviously. and this ain't very well set up OS. My original Dothan OS w/ dfi mobo was hitting a bit higher scores clock to clock if I remember correctly. Need to reinstall WinXP and see if it helps.

Here you can see a compare between that run, and my P4C @ FSB238 (4046Mhz) 1:1 2-2-2-5-64us, at very similar card clocks.

Darn i want a dothan.

[macci]

Got a nice round number this time

The Dorthan's just a bit over 3000 points behind your Winchester @ almost the same clocks speeds on CPU and GPU. It's damn nice work though! You're just the man to keep our hopes in Dorthan alive!

It would be kinda cool to see an FX55 @ 141x19, single channel and XT@636/639

Hi,

i am stuck with my AOpen i855 at 137 MHz FSB.

Has anybody some detailed pictures about a Chipset Voltage Mod for the AOpen Board?
Actually I only find mods for the DFI one,

cya, Simon

thx mate
yep , no heavy mods yet ,i'm js usin an ocz booster and a little north cooler mod

Glad too se that my waterblock will fit.. using the same

really good job from zalman ,the cylinder form and the small(?)size sounds great for almost boards.
and i`m tryin to fit this k8's block for the next round.
k8 block

How high can the booster get on the AOpen board?

up the agp/pci speed.

*edit* wrong pic, sorry.

I don't have the link anymore but luckily I still have it on the HD

for more mods, maybe someone else can help you out or PM kyosen/k-ohashi

*edit bis* uploading doesn't work when editing I'll make new post then...

and another *edit*

I couldn't upload cuz' the pic was too big

but I found a link





what's a very robust vidcard pci/agp clock wise? nothing too fancy...

[macci]

Like I said Mark03 looks a bit better than 2k1

Its a very nice score for those card clocks. Winchester at 2.52G w/ card @660/620 hit only 14988.

[BitpowerPM]

Yeah i got the new BIOS Version 1.05 and now i can push up the FSB upto 164 MHz at a multiplier of 16x.

I Think my Pentium M 745 1,8 GHz stuck at ca. 2470 MHz without V-Core Mod.
But 31 sec SuperPi is really nice for beginning.

System: AOPen i855...
Dothan 1,8
512 MB TwinMOS TwiSTER PC3200 pro 2-2-2-5 FSB:RAM ratio (164 MHz FSB) 3:4
Tagan 380 Watts NT

Maybe V-Core is coming next week.

Can you say OUCH



Tip: dont try to install XP120 on top of Dothan chip

Chip is alive and kicking. Not the best clocker thou - maxes at around 2.7GHz aircooled. Seems that the 'made in Philippines' dothans dont really like higher volts at all. The Malay chips seem to respond loads better.
So far the 1.7G chip has given the highest CPU speed for me (2760MHz aircooled). 1.5G would have gone even higher but mobo limits it.

Well....same story as always with the Intel cpus in the past ...Philippine ones tend to not respond to higher voltage and OC like pure crap.

Good to hear that the 2.1ghz is stille alive...would have been a real PITA to kill that one.


I´m eager to get my gear going...got my cpu next me and my mobo is at the postoffice...just waitning to get picked up.
Only sad thing is..I just checked my cpu and it´s a Philippine
Just have to hope for the best.

Is anyone having issues with the DFI board and x800xt pe driver crashes? I think it must be the agp/pci speed.....I'm using 12/10 BIOS, and have tried 33/66 and 36/69 and still have the same prob....my 9600x works fine up to 160fsb....

Macci, Yeah I think the 1.7 is the best deal, mine runs 2701(160fsb) max, at 1.59v. I have a 2.0 coming Monday or Tuesday.....
Fortunately I got both cheap, $209 for 735 and $215 for 755.
So after reflection, how do you compare DFI to Aopen?

where on earth would you get a 755 for $215 but ebay? insane!
maybe the aopen is the better choice. iirc the pci/agp lock is working. so that should take care of the problems with the high fsb having vidcards crap out.

oh and was that 2.7g on air or already some di goodness?

2.7 was on air
I just used the pin mod to 1.59V and attached the Swiftech MCX159 Northbridge Cooler, and VOILA! Oc'ed like MAD... sPi stable at 2692mHz @ 29s

[Shade00]

What kind of temps are you getting with that speed and voltage, charlie?

[charlie]

idling mid 30's and loaded once I saw 49C

[macci]

yes. I saw the 'VPU Recorvery' thing way too often w/ DFI. Should be stable up to around 133FSB right?
With AOpen I haven't seen anything like that yet.
