Nice job man. I tried but couldn't catch you. :)

Thank you!

I'm not very happy with this combo jet- 260MHz is max FSB I get. But mem timings is lowest possible and 2x512MB dimms is not so easy like 2x256.

Then monitoring Vnb volage with oscilloscope I've see quite big pulsation @load.

Adding bigger LowESR+ceramic+tantalum caps help, but can't eliminate them.

Other voltages are ok, no drops.

But perfomance is ok, you can compare it @2200MHz:
