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)

I have 4x1GB on my P5B-D & E6600. It runs error free in memtest at 9x333/1000/4-4-4-10/2.15v
I was also able to run these sticks error free at 1066/5-5-5-15/2.25v, but only by raising the NB voltage to 1.45v.
I attached the 1000FSB BIOS config file I use. You can give it a try if you'd like.

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

I can run these PC8500 sticks at 800/3-3-3-10/2.25v w/o raising any other voltages.

You might have a "better" copy of that board than I.
