A7V133 Raid not stable above 149mhz

[redraven]

I have a A7V133 Raid, running a AVIA0109 1g @ 1.4g with Mushkin PC150 and Thermoengine, It won't post at 150 or higher even with all the settings slowed down. Is this a northbridge cooling problem, or could it be just the board being a bad revision or just running at its limits.
I've seen the same board running at 155+ no probs..
I tried dropping the multiplier right down to 7 and it still won't go, so its not a CPU limitation.

Ideas anyone..?

149/4 = 37.25 MHz. The out of spec PCI clock is messing up your IDE-based RAID controller.

You're that far out of spec w/ a RAID 0? I'd back up your OS, just in case it gets corrupt and you have to rebuild.

Sorry, I meant the board can't get stable over 149mhz.
I have a habit of confusing people
I have since found out that I have an early northbridge revision chip and consequently doesn't allow high FSB's (bugger).
I have fitted a good heatsink/fan to it and that now allows me to get to 152fsb but 150 is the sweetspot, and no I don't get any raid or hd troubles.
