Does any one know the Max fsb on an AW8

Deanzo · Aug 12, 2006

As the title says does any one here know what the Max fsb is on the AW8 / AW8 Max
I can post fine at 340 but not any higher
Or has anyone had there fsb higher than 340 on this board and if so what was it.

I do sooo like looking at this picture.
But more would all ways be better :clap:

And a 4.8 Suicide Screenshot on Air would be cool

If you were able to get 340 FSB out of your AW8, you are doing a little better than me.

Deanzo · Aug 12, 2006

This board, chip and ram all seem to like each other.
but I do think its the fsb thats stoping me go any higher

dicecca112 · Aug 12, 2006

that you can get above 245 is what floors me.

Finally found my old O/C notes. Looks like 315 was about my highest stable FSB. I was able to boot at 320, but it sure wasn't stable at that speed. That was with my old 3.8 Prescott using the 14X multiplier, so it was probably getting close to the CPU's limit too.

I hit 300fsb no problem, and just stopped...didn't really try and see if it would go any higher...

dicecca112 · Aug 12, 2006

I'm working on something over at the Abit forums, what ram did you use for it, and do you know what ICs they are?

Deanzo · Aug 14, 2006

Sorry for the late reply, I had to go out of town for work and Ive only just got back in the door...

Thanks for the input guys, now to answer some questions.
340 fsb isn't stable for any thing but at 330 or 4.6ghz I can bench 3Dmark01 http://service.futuremark.com/compare?2k1=9024782 but not 06 or PCmark04
At 300 I can bench any thing so far 100% stable

On the subject od Vcore
300 @ 1.375 100% stable
320 @ 1.4 stable so far (24/7 testing not done yet)
330 @ 1.45 only stable for super pi and 3Dmark01
340 @ 1.55 suicide screenshot only (didnt try any thing else to scared)

I cant tell you off hand what the IC's the ram is (as I dont know what that is to start with) but I can link you to the ram I have, if that helps http://www.dragonpc.co.nz/p.aspx?69096 4 of them in total
Let me know if you need any thing else.
I may all so ask over there to see if any one has had any luck over 340

A couple of other things I thought I'd say.

Im sure its the fsb holding me back as if I boot at 339 or any thing lower and then use uGuru to clock it up, as soon as i go over 340 it locks up and when I re-boot it wont do anything, wont even let me access the bios I have to reset the cmos first.

All testing is done using my XP120 to cool the chip with a 80cfm fan and AS5.
Kind of makes me think what this chip would do with better cooling and a higher fsb or multi

I have also got it to post at 339fsb with 1.45volts in the bios you can see in the picture below the drop

You are reaching the limit on the CPU, probably in addition to the FSB limit on the mobo. Temps must be smokin' hot on air during that suicide run.

What are you trying to say, 6C on my CPU Temp in uGuru isn't right ??
Next you'll be telling me Santa isn't real :santa:

Have you tried running just 2 sticks of ram instead of 4???

Deanzo · Aug 14, 2006

Ive done a bit more reading and found this on the Abit website under the bios for the AW8D

BIOS: aw8d11.zip Bios Issue Date:2006/03/20
Mirror Site: ASIA Europe US
BIOS ID:1.1
1: Enhanced compatibility with certain HDDs.
2: Enhanced compatibility with certain storage cards.
3: Fixed the issue that the external clock cannot be set higher than 340MHz.
4: BIOS compiled date: 03/20/2006

Now as the AW8 is its little brother 340fsb could be all she's got

Now how am I going to hit 4.8

No but if you think it would help I'll give it a go later tonight when it gets cooler

3: Fixed the issue that the external clock cannot be set higher than 340MHz.

it may have but has't fixed the memory incompatibility. Be happy your board hits 300 and not 245 and no higher like mine

Deanzo · Aug 14, 2006

I know this is going to sound dumb as I sit here looking at all your white stars
But........
Im going to take it you bios will looks kind of like mine,
In the uGuru utility have you changed the N/B Strap CPU to PSB1066 so it dumbs your ram down to 533 and run it at 1:1 ?

dicecca112 · Aug 14, 2006

hahah, white stars mean nothing. I have and it did nothing

Well maybe "modesty"

Ive posted over on the Abit Fourm as you may have seen but I dont think Im going to have much luck there so Ive filled in a questionaire sheet to Abit technical support on this issue and the low temp readings

Ive got this back, so now its just a wait and see

Thank you for e-mailing ABIT. This is an automatic reply to inform that your message has been well received.We will check and come back to you very soon

It might help...I've seen even wierder things like putting the ram in the second slots instead of the first ones to get higher speed...

Does any one know the Max fsb on an AW8
