ABit AX78 Overclocking/Stability

[LIKMARK]

Sorry for the delay LIKMARK, I've had many many issues and only made posts I can risk losing - lost my post to you about 8 times before I quit [unstable Phenom]

No problem

It looks like you have a BIOS limitation or a CPU limitation, as 9500/9600/9700 should be capable of dropping NB multi. I had one 9600BE which did not drop NB multi in the same BIOS which dropped NB multi for the second 9600BE, so its very possible

I love inconsistency..... Makes things so much easier pinpointing...

It's a Phenom limitation, yup. They don't oc RAM well although 3-3-3-3-11 1T 450, 4-4-4-4-11 1T 500 and 5-5-5-15 600 is easy on them at 2.2v if MEMs can do it.

That's with two sticks right?

Your board is better for RAM/Monitoring than the DFI 70FX, try one of those and try getting some good stability and accuracy, or RAM compatibility and RAM oc, and you'll see why
Their BIOS has tons of good options but also tons of problems with basics settings and options. They are improving but since Nov'07, not enough.

Yea I know, really bad example there I saw that as soon as i wrote it. Its beginning to look like the last AMD chipset board DFI made.. crfx3200 or what it's called. Brilliant when you made it work, but pure hassle for most of the time.

They wouldn't have added an 8-pin 12V connector if it couldn't support above 16A CPU draw

That's what I'm thinking too, one of the reasons why I bought this board.

Your oc'd 9500 runs at minimum 126W TDP, if you take 95W TDP being stock. You're using the same hardware voltages and CPU/NB speeds as 9850BE does, and the current draw is the same, so is the end power.

I thought 95W was ACP, not TDP. TDP being about 120W for the 9500/9600

Anyway, I'll talk with an Abit rep today and find out if 9850BE is officially supported and with which BIOS.

Case closed

Which is the most stable BIOS ATM BTW?

I've only tried #12 so far.

KTE, I just found one person who has tested ax78 with 9850BE (been searching for days lol). --> http://forum.uabit.com/showthread.php?t=137048&page=2
He mentioned that there is no sign of PWM problem....so I guess it's your BIOS? BTW, he haven't stress that CPU enough to be 100% sure the PWM is a non-issue. He has problems with detecting the HDDs, so i guess it's still remain to be seen if the mobo can handle it under full load.

At the same thread, someone pointed out that he blew a MOSFET when ocing an x2 6000+ (125W TDP) within 4 days. But it has been running without any problem for a week after replacing the mobo (RMA).

Basically down to getting a bad board I think.

Thanks

On another note, the mod there showed how to access CPU/NB FIDs in the BIOS: http://forum.uabit.com/showpost.php?...9&postcount=15

Actually he shows a noob how to unlock cpu fid by disabling C'n'Q....

BTW, I have clarified 4 months ago with Abit and they did not get any problems with running RAM at 1.8-2.3v with this board and Phenoms, even after I gave them instructions to test what I thought was highly likely a Phenom killer setting

I'm running my ram at 2.2v ATM. Just to test this. (low vcore/imc - high vdimm)

Wouldn't mind if my Phenom died of this as it oc's horribly. Early version....
