DDR400 RAM won´t run at 200MHz?

Question

What can this be? First off my specs:
- A64 Venice 3200+ (cooled by ZalmanCNPS7000AlCu, all temps ok)
- MSI K8N Neo2 Platinum (BIOS v1.8 )
- 2x 1024MB DDR400 OCZ Performance
With some overclocking guides I got these max values:
- HTT Max: 300
- CPU Max: 250
- RAM Max: 215
My settings:
- 10x235
- HTT x3
- VCore 1,475v+5.0%
- RAM-Teiler 166 (=195MHz @ 2350MHz)
- Timings 3,3,3,8,1T
- VDimm 2,6v
- disabled: Spread, Q&C, Aggressive Timings
Normally I would set everything to 240/200 or 250/207 with a RAM divider of 166. But this won´t work! Somehow I not even get 200MHz with this divider. I reach the CPU´s Max at a 100 divider, and I reach 215 with a 200 divider. But 166 makes me nuts. Is it a bug?
I hope someone can help me, or show me a link, where this has been already discussed. Sorry, if it has been discussed before, this is my first visit here

Good benchmark. Seems as if I can forget 4x 512. I wonder if I have more chances with the ASUS A8V Deluxe and my 2x 1024MB if there´s really a bug in MSI´s BIOS. It can´t be that my RAM runs up to 199MHz and then locks up everything...
Yes, I got an ASUS A8V Deluxe rev2, myself and I will make some tests with that MoBo / Venice / 4x512, in the days to come.
However, their latest beta biosversions 1014.006 are horrible regarding voltagecontrol ( extrem overvolting ) and mem.dividers logic.
The 1011 with venice support seems ok except for the 1T/2T control ( same result no matter what enabled / disabled / auto-setting).
I would most of all, see a new good written venice-bios version for the MSI Neo2 MoBo.
By the way did try higher RAM Voltage, like 2.7 -2.8v ?
Does not hurt running memtest86 as well.
