The results of memc are below. It looks like the backplane is running at 133 MHz, not 150.
I believe the router has been configured with the last sb_clock_table[] entry in:

Looks like it has been about 5 days since the last post - has anyone's router gone poof yet?
Hacksaw.
Good question. If we're counting, I have personally set 2 routers to 300MHz.

Here is a question...
I left my router on for 24 hours with the HDD spinning. The brick is damn hot. Would attaching a USB fan help out with the heat dissipation?
Without taking the router apart, I can't tell if there is any airflow access to internal components. Would cooling on the top or bottom be better? I am standing mine up so I have access to both sides.

Mine gets pretty warm when the HDD is spinning, but I wouldn't call it "damn hot".
I'd have to say that trying to reduce the temperature of any of the important components with external airflow would be largely ineffective. The HDD is completely sealed in a metal box. The CPU and SDRAM are also buried under a metal EMC shield. To complicate things further, they're on opposite sides of the router.
IMHO, the long-term reliability of the HDD will suffer because it's packaged so tightly in the router. I believe that idling the HDD to keep it as cool as possible when not in use is one of the best thing that can be done to improve its reliability. The electronics really don't care.

nice you are trying to get the most out of the wl700 but none of you have written anything about expected, and actual performance gains. Can anyone elaborate on this?

Usually, Oleg recommends to avoid doing that unless you ensured better heat dissipation for the CPU, i.e. attach a heatsink to it.
My wl500gp runs @300Mhz for several months now, but some guys were not able to even boot @300Mhz (i.e. bricked the box, but recovered using a console), but clkfreq=288,144 worked fine for them. My other wl500gp with 128mb of ram was unstable @300Mhz (i.e. showed memory errors during tests), it's running @264Mhz now.
And yes, I've a heatsink attached.
IO performance does not change, as PCI is still running @33Mhz.
I don't think the 30 mhz will make such a big difference. At least, not as much as I would like to see for the pain it costs to recover it. 300 mhz would be nice though, but the probable need for a heatsink makes it less interesting.
