A7N8X-E Memory Problems

I'm building two A7N8X-E based systems:

Gladly I decided to equip one with an XP 2800-333 and 2x 512MB 333
Infinion. This box works fine. (except for the RAID problem mentioned
in the other thread)

But for the other box I decided to use an XP 3200-400 and 2x 512MB 400
Infinion. (I should have listen to my stomach and go for a 3000-333)

I can't get the memory to run reliable at 400 MHz: www.(memtest86.com)
2 x Infinion @400 Mhz @ different timings BIOS 1007

I exchanged the RAM at the shop:
2 x TwinMos @400 Mhz @ different timings
1 x TwinMos @400 Mhz @ different timings

I changed back to the Infinion:
I tryed to flash 1008 with awdflash, but I needed to make it via the
Autoexec.bat option from Ben Popes page (thx!) to get it flashed, but
still no luck with it: (But seems to be a bit better)
2 x Infinion @400 Mhz @ different timings BIOS 1007

As a solution I run the memory asynchron to the FSB:
XP3200-400 / DDR333
But I'm not satisfyed, because the system was to expensive to run
handycaped. (but memtest gives it a slightly better value for the
memory bandwith than the 2800-333 system, so async seems not as bad as
I would have suggested)

Anybody with similar problems?

Any ideas?

Try upping the voltage on the memory - 2.7V should be enough.

You're a braver man than I to flash when you know memory is unstable.

Are you sure it is the memory failing and not the processor? Can the
processor run with a 400MHz FSB? Also, there have been numberous
posting on this NG that the nVidia chipset is not stable running the
memory bus and processor bus at different clock speeds. Anyway, your
memory may be fine.

I already tried that without success. (But I don't know if I tryed it
with BIOS 1008)

NO! I'm not STUPID! :-)
Of course I did it with a stable memory setting at 333.

thx!
