Asus A8N-E Pci Lock Problem

[Lucu]

Hi

I have this a8n-e and a 3000 (e6) venice.
I had overclocked it to around 2250 following one of the guides in this forum, with no problems, it was my first overclock and because of that and my cheap ram i was satisfied.

I left it that way for a couple of weeks, and then i decided to try and squeeze a little more out of it, i followed the same procedure i followed the first time but to my surprise pci lock was not functioning, it raised at the same time i raised htt on clockgen.

So I upgraded the bios to 1008 from 1006 although 1006 had already allowed me to overclock fine once, but it didn't solve the problem.

Does anyone know how to solve this ?

Thanks in advance.

U'll have to set the PCI clock to 33.33 in the BIOS. Go to Advanced ----> JumperFree Configuration and under that the last option would be the one for the PCI bus. U'll have 3 options - 1. Auto 2. To CPU and 3. 33.33. Change it to 33.33 and ur good to go. It's the PCI-E bus which is automatically locked at 100 MHz by default in a new MOBO. The PCI bus has to be locked manually.

What guide?

it seems I didn't make myself clear, sorry.

I have set it in the bios to 33.33 mhz, but it does not lock, and as a curiosity clockgen doesn't even show 33.33 mhz it shows 33.58 mhz, before I up the htt.

Then try the Auto setting and up the FSB by maybe just 5~10 MHz and check if the PCI bus speed increases or not. Also make sure that the Floppy Drive is enabled in the BIOS coz' this board seems to have an issue with OC'ing and the floppy drive disabled.

To me, it looks like 33.58MHz is just a variance issue.

The stuck HTT problem can be solved by either using BIOS 1001 or flashing to the latest BIOS in DOS (not in Windows!), loading defaults, saving then return to the BIOS to do your tweaking.
