Corsair DDR2 6400 incompatible with Asus P5B?

I recently built my first computer with Asus P5B motherboard and 2GB of Corsair TWIN2X2048-6400. The modules are said to be good at 800Mhz 5-5-5-12 and 1.9v

The system sometimes reboot for no reasons, so I ran windows memory diagnostic and the memory modules failed the ERAND test. I tried manually set the DDR voltage in BIOS. The modules passed the overnight memory test at 1.8v. However the test produced errors at the default 1.9v. If I set the voltage to 2.0v or 2.1v, the test produces even more errors. How could this happen? I always thought that higher voltage means more stability. Could anyone here explain to me?

Also the SPD timing is 5-5-5-18, not the claimed 5-5-5-12. If I set the timing to 5-5-5-12 manually they the modules become unstable. How disappointing!

My system configuration:
Asus P5B
Intel Core 2 Duo E6600
Corsair TWIN2X2048-6400
eVGA GeForce 7600 GT KO
Antec P150 case with Neo HE 430 PSU

Corsair memory is usually quite reliable on Asus boards unless the bios needs an update. On the last build here Corsair dimms started seeing errors. The replacement memory saw even more after the cpu fan quit. A cpu temp problem? Within a month's time the brand new Kingston dimms saw 573 errors when memtest was run on them. It wasn't either brand of memory. The two things to look at after returning to the defaults would be temps and the supply being a 430w model with a 20pin main power connector. That model board requires a 24pin power connector according to the specifications seen at http://www.newegg.com/Product/Product.asp?Item=N82E16813131045 and in the A1 specifications section in the online manual seen at http://dlsvr01.asus.com/pub/ASUS/mb/socket775/P5B/e2620_p5b_b.pdf

it could be just an incompatability, I have seen corsair memory act janky on tons of different systems. I think its speeds and its performance cause stability issues and bottle necks.

I used to work for a microsoft reseller and AASP on their service side and build custom PCs for people/companies and I ran into similiar problems as you have with corsair memory. I ended up usually just going with crucial or viking, or even some generic ram and never had those problems.
 
Lately I have been running Kingston memory on Asus boards without problems. But some model boards can be touchy with certain brands. When the memory was installed on the new build after seeing those 573 errors none were seen. But DDR2 is a new type and design to work with. I would hate to see Corsair ruled out for Asus boards. But the choice for boards may see an MSI rather then Asus model on the next one.
