P5B-Deluxe and Ballistix PC2-8500 problem

I just bought a pair of BL2KIT12864AA1065 and they will work in any mode except the fastest two. These work fine: 1:1 (533 MHz), 4:5 (667 MHz), and 2:3 (800 MHz). If I boot them in in 3:5 (889 MHz) or 1:2 (1,066 MHz) windows will not start.

If I boot into Memtest86+ v1.70, they give TONS of errors in the faster two modes, but are just fine in the lower 3 modes... I've tried manually setting the timings/voltage and also letting the board do it with no luck either case. I'm using 5-5-5-15-4-30-10-10-10-11 @ 2.25 v initially.

I have a P5B-Deluxe running BIOS 1215. Anyone else out there have this board with these sticks? I'm thinking since I get errors at the higher modes, it's my board, not the memory.

Opinions are welcome.

Thanks!
Additional info: q6600, x1950 pro 512 meg. I normally run the system @ 9x333 @ 1.2625vcore with my old memory (DDR2-800 ballistix @ 1:1 with these timings: 4-4-4-12-4-20-10-10-10-11)

Thanks for the info. Turns out I had to jack the NBVcore up 2 notches and the ICH up to it's highest setting to run error-free @ PC7100 (1,111 MHz). Not worth it to me when I can run my older Ballistix (DDR2-800) @ PC4300 (667 MHz) @ 3-3-3-6 :p

No so good RAMs will force you to jackup voltage. In general, if you see DDR2 800 rated at 2.0-2.2V, then move one. High quality DDR2 800 RAMs should be able to hit 4-4-4-12-2T with 1.8Vdimm and no change in Vcore, NB, and SB.

100% incorrect.

Higher FSB and Higher Memory Speed will cause you to raise NB voltage. This is regardless of which type of ram you are using, even your fancy smancy JEDEC value ram than performs better than highly binned DDR2.

SDRAM, DDR, DDR2, and DDR3 all have done this.
