How about 38,7k in 2k6 with cascade?

[hiwa]

To be honest I can't tell you because I don't know.
Everytime we try to set RTL manually our system won't boot so we stay on AUTO here. Therefore I can't say the used values.
We will try these settings. Not sure if our rig will post but we will give it a try.

with that ram freq and uncore i am pretty sure classi setted them over 63
dipend on your memories too,this settings needs crazy moduls
if system don't boot try relax them and set +1 higher, try max 63 for last channel like 59/61/63

it's very important option for 05/06 and specialy 32m

Good Luck
