[REQUEST] Tyan K8W S2885 OCing unlock (AMI bios)

[vlad01]

I can change the multiplier via software only down from the max. FSB is not available on any software including the AMD official one. This I assume is because it's not enabled in the bios code which is why I want to have in unlocked.

RAM frequency is available in the bios and can be changed though it defaults back to the SPD values when rebooting.

Is there a AMI tool that works with this bios? as it appears all the ones on this site are too new. I think it is AMIBIOS8 but I searched for days for this tool with no luck. I would try myself if I could find a tool that can open my bios.

I have confirmed it is an AMIBIOS8  based bios as it is stated in the manual. See the attached screen shot. 

Does anyone have the amibios8 tool?

I see in datasheet of clockgen ICS950405 no DRAM lines, so surprize how bios it is change.
So next assumption may be wrong(about FSB)

it's not enabled in the bios code

I think - not include. So need write some mashine code to add support for change FSB.
Can you find your model clockgen on motherboard ? Try programm SetFSB.

if I could find a tool

Search by keywords "AMIBCP + v3.37"

I found the ampbcp a few hours ago on a Russian site. I can see there is overclocking stuff there set as reserved but looks like just voltage and multiplier, didn't see FSB options.



The clock gen is this one.
