still can't work out what aod is changing that i haven't done in bios myself that can cause a drop in performance. meh, will track it down eventually.

The AOD button? Or a half enabled patch?

What I suspect it a stored value from learned settings eventually comes back to bite your tail when you progressively OC. From these experiences, you have to pull the RAM and drop one stick of different timing RAM to get the number(s) to correct settings.
Anyone want to back up or prove this wrong, go for it. I would just like to see my board work.

This is exactly what happened with my Phenoms on both a DFI and an MSI. Esp. if you use AOD to get a failed oc, when it reboots, the BIOS doesn't clear the settings, so you fail bootup until you clear CMOS, but the problem is, *some* BIOS settings don't get cleared even with the battery out unless you leave the system off without power for over 8-9 hours. Then you can attempt to boot with minimal components installed and just one DIMM and it should work fine... until you repeat such a procedure. Many times that'll kill your Windows install totally, I mean you won't be able to recover your HD docs which makes me think, it's actually the PCIe gettin stuck at highr than 100MHz which causes these problems in the first place

I am still working on it with the devs to see if its a BIOS issue but I have tried clocking using AOD at time, closed it and restarted it to see the PCIe at plus 120MHz, sometimes reading 150-190MHz and then crashing.

I have just noticed that cpuz 1.43 & 1.44 are both reporting my PCIe slot running at 8x. Has anyone else noticed this.
I can't find anything in bios to change it. It's currently set on auto.

I'm using F4B bios.

with cpuz 1.44.1 , bios F4B and 5000BE i have pcie on 16x.
2 of the pcie slots are 8x and the other 2 are 16x.
you have the card not in the first slot near the cpu?

[Aussie FX]

Yeah it's in the top slot

Hi Folks, I just picked up a 790FX-DS5.
How similar is this for OC'ing to the DQ6?

I guess what I'm asking is can I use the info from this thread on the DS5?
Any BIOS preference using a Phenom BE?

Thanks in advance.... Dave

Hi Dave, yep it's pretty much the same as a DQ6. F4B is the latest Beta bios and it's nice and stable.

I still can't get my pci-e slot to run at 16x. I ran optimised defaults in bios to try to fix it - no luck.

Does anyone know where you change the pci-e speeds on this mobo?
I'm stuffed if I can find it
