P5B-Deluxe and Ballistix PC2-8500 problem

[graysky]

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)

waht if you overcock the front side bus and keep the memory divider at 2:3? Is is stable above 800MHz?

I'm curious to see if it's something with certain dividers.

Yeah... 333 is fine... I just don't know if the sticks are bad or if it's my board. I'm on my way to buy some rip off pc8500 from a local shop to see if the board can run 'em... these sticks could be bad... I've never had memory work at lower speeds and NOT at higher speeds....
