AOpen i975X YDGa Problem Solving thread

> Does your board go above the 230s?

It's OK upto about 246MHz with my T2600(ES, stepping:4),
but upto about 235MHz with my T2600(Retail, stepping:8).
As we can see that several T2600(ES, stepping:8) are running awesome,
I think that stepping itself is not important for FSB limitation...

I've done the Vcca mod, and checked its effect.

Increasing R151 gives higher Vcca.

I tried upto 1.7V Vcca, and got +2MHz FSB...only 2MHz:(
I don't know proper Vcca value, though...

to bad... good you tried kyosen :(
man. im still getting gasoline :P

kyosen, and what are real effects of increased vcca? higher fsb, oc?

He said it right below the picture... Just 2mhz higher on the fsb

Damn this is not good... still I am getting one. So how does this sum up?? CPU(s) are overall dud (OC-Wise)?? As Board (FSB) seems to go up, till CPU(s) can take it.

Sorry, i didn't notice that. With dothans real gain showed above 2v for me, so I think we could easily try a bit more vcca.

Quite the opposite it would seem. Even if people drop the multiplier on the CPU they cannot raise the FSB any higher even with the reduced CPU speed.

Did anyone try 200/266fsb pin mod? Sorry if I missed it

But that is just a problem specific to this motherboard so far.

Remember, theres only two (or is the ASUS out now?) mobos on the market for Yonah. MSI and Aopen.

Somebody can't imagine that a bios later will support ES yonah multip. unlock? (last chance :rolleyes: )

no... as said only downwards.

I agree, I saw no gain at all with my dothan at 1.8v VCCA over the stock 1.5v (which is the same as for yonah) Only by going over and above 2v was I able to see real gains (275Mhz stable @ 2.5v vcca over 250Mhz at stock vcca).

A complete silence about the pinmod.

I repeat, did _anyone_ try the pinmod?

Kyosen.. can you try 2v+ on vcca?
if this gaines fsb..

Off topic, but is does anyone have a model number or link to the MSI board that supports Yonah?

Please, it's a very important question

yes, somebody please try the pinmod

has any one looked at aopens bios to see if their are any hidden settings they can unhide ?
ie 1:1ram ratio ?

if someone would try a pinmod he could only run default mp with 266fsb.. this would mean way more then aircooling could handle. so only with phase or dry ice / ln2.

Might be worth a go with say a T2300? That way would bring the clock speed down to possibly workable levels.

or with an ES cpu, unlocked multi to 8*266 instead of 13*166, that's worth a try :)
