Here is dual channel run with adjusted ODT.



Since ODT cannot be adjusted (on Asus) from the bios and it is impossible to get in Windows without adjusting (if tCL is under 10CLK) it I have to boot with 470FSB and use clockgen to get higher. When booting under 500FSB the transaction booster / performance level must be loosen a bit because otherwise you won´t reach 500FSB. Of course when booting at 500FSB it will be automatically loosen as the "strap" changes at 500FSB.

ODT can actually be adjusted with tools available to public.
I use the good ol' WPCREDIT and Pmem combination for all of the adjustments.

Unfortunately my board seem to get worse and worse.
Few days ago I had no problem doing 2000MHz / 1T in single channel, today I cannot even get in to Windows with the same settings

There is no difference in MCH temps or voltage.
The chip just cannot do it any more.

Seems that using 1.8V will damage the MCH really fast. It is not a surprise thou, since it is a 90nm part and even the 975X (130nm) could be damaged with 1.8V+ in prolonged use.

I would like to see if there is any difference in ODT register configuration on Blitz compared to P5K3.
