BIOS 0036 and 0037 solved a couple of overclocking problems. It is now possible to change multipliers and their values seem to stick.
What is still a problem is that in the performance screen of the BIOS:
Burst Mode Power Limit (default value = 118)
Sustained Mode Power Limit (default value = 95)
are white in the BIOS screen but cannot be changed 
When doing a stress test with 1 thread the Processor Frequency goes to the configured frequency (all multipliers are configured identical). When doing stress test with more than 1 thread the Power Limit becomes very quickly the bottleneck.
In XTU and HWiNFO64 v4.02-1700 the Turbo Boost Power Max values are even displayed as 4095,875.
Observed on DZ68BC, AA30742-401 with i7-2600K.
Hello,
Thank you for your feedback. We will make sure your comment reaches the correct department for future consideration.
Thanks for forwarding it.
I have found a kind of workaround. By setting the overclocking to automatic and select a higher ratio the automatic algorithm will update the power limits. Switching back to manual allows then to change the other settings.
During performance measurements it seems however to me that this setting is just visual as higher values don't seem to have effect (as it did in BIOS 0028)
I really like the hardware build quality of the DZ68BC and the clear documentation, it is a shame that the BIOS quality isn't as good.
Hi Dan,
Is there any update on this issue? Wondering if there will be a BIOS update for the DZ68BC that solves this problem.

Installed BIOS 0039. The issue is still present
