Dual Channel Memmory Errors

[coliver]

I have an Asus A8N-SLI Deluxe mobo, AMD 64 3800, and 2 sticks of VS1GB400C3(1MB Value select 3200), With both sticks in a dual channel memory cofiguration i get an error with memtest(latest version) at test 7 (257.6MB) on every pass; and occasionally get an error on test 8 (2047.6MB). When I test each stick separatly I get no errors. What gives?

 

My Bios settings are as follows:

 

Dim volt - 2.80 volts

Legacy USB: Disabled

Latency settings at - 2.5-3-3-8

No overclocking of CPU or Memory

Flashed bios with latest version for Asus web site

 

Thanks for any help u can give me.

I'd compare my bios settings to the listed settings on the first page of the following link:

These worked perectly for me and most others even though it's for revision 1006. (now up to 1007, I'm still using 1006 because its stable as a rock)

And can you tell me the make and model of PSY and video card you have installed?

By PSY im assuming a typo for PSU: Cooler Master 450W Real Power, Model RS-450-ACLY.

 

Graphics: EVGA e-geforce 6800 GT, with the 6 pin adapter hooked up to 2 of the peripheral powerconnectors, alone(no other devices on the same cord).

 

My system also has:

 

WD 74G Raptor Drive

DVD Rom Drive

Sound BLaster Audigy ZS

 

Thanks for the Reply

I am not sure that PSU will meet the MB makers requirements. Please check that you have an ATX 2.0 compliant PSU and I would suggest 500 Watt Minimum with that configuration.

I agree with Ram Guy. The amperage on the +12volt rails is way to low. The following link states 12amps on one rail and 10 on the other:

You're gonna need more like 18 and 16 amps on a two +12 volt rails supply or 28 amps on a single +12 volt rail supply (minimum) for stability with this board.
