Ok guys,

We have problems we have to work out. As many people will get this problem

=============================================

Problems occure: stuck FSB

when?

No difference between:

- step 4 and step 8 cpu's
- Pci-e clocks to even 140mhz
- pci-e voltage to max
- Northbridge voltage to max
- vcore voltage with mods to even 1.6v
- Many differrent ddr2 sticks from different brands
- Cooling from better aircooling to even -190°c and no difference
- I changed the cooling paste on the northbridge cooler
- I placed a big fan on the northbrigde cooler
- from sample bios to the beta bios
- placed memmory in other dimm's
- i ran single channel
- i used clockgen so in windows on the fly overclocking
- i used many memmory settings

=======================================

So what would it be..

Hicookie has the same problems as me.
We both have a Rev 00A bord (he has retail. i have sample)

If you have an other rev.. please post

please post comments in order to help if you have tested!

maybe in need of more VCCA like the dothans?

[cirthix]

i doubt it, there would be a larger range of instability then

i'm guessing bios. newegg is showing 1066fsb support, so they better update it soon!

[Waus-mod]

i got the newest beta bios.. still doesnt change the problem.

[lawrywild]

Check what week your PLL was made and see if there's a dodgy week or something...

well... I know that with my dothan it booted fine 255 but 256 was a NO GO

yes but that problem was to do with vcca on the adapter.

[Waus-mod]

or its the rev of the baord.. or the 1066 support wich also means an other rev.
it cant be something else!

maybe

I hope it isnt

[lawrywild]

there wasn't a problem at all... it just needed more.

the adapter supplied stock voltages perfectly.

These Yonahs still use a VCCA supply so it's no different.

[lawrywild]

Here we are:

well if the "PLL Supply Voltage" was increased, FSB wall may increase right?

[Waus-mod]

the main weird thing is that our boards are stuck... and the ones from tarosa and tam are out of the box doing 275mhz. So i still say its the revision.

yeh, true say..

[wwwww]

I have the same prob, stuck at 224FSB.

Tried NB volts, PCI vid card, 2 sticks of ram, better chipset cooling and a few bios settings, no luck.

[wwwww]

Finished PI 1M @ 225FSB!!!

And she's still stable!!!

Did a few changes, just gonna check which one worked or if I just got lucky and it's gonna freeze at 226...


nup 226 froze at loop 3 - but she's getting better.


What clockgen are we using?

[Miwo]

lol, what did you do to get an increase of 1FSB wwwww?
Some random bios changes? Just curious

I set tRas to 12 (Cpuz 16) - definately on 12 though, my sticks won't do tRas above 12.

However when I raised Vcore to 1.5V it was unstable at 225 again.

Trying again at 1.4 atm,

yep seems stable enough, just finished two 1M loops...and died on 3rd

[Waus-mod]

i had the same wwwwww... but youre still to a wall sometimes.

[Waus-mod]

doesnt matter! he tried 8 differnt brands. and hicookie also tried other brands.

update @ startpost.

[Waus-mod]

The working boards are out of the box performing like that... our's not.

[lawrywild]

I stick to my VCCA comment...

[Waus-mod]

but if it is the vcca who do the other boards go so high out of the box

[lawrywild]

but if it is the vcca who do the other boards go so high out of the box

improved VCCA supply

[Waus-mod]

they didnt mod anything according to prjapan

[hipro5]

Could you guys plese try to boot at 1:1 CPU:Ram in case the mobo has some issues with the deviders?........

ALSO EVEN 275MHz are not enough......
