What's the error code? How long did you run Memtest? Did you let it run for at least 2 complete pass?

Edit: Since you're using four dual-sided 2 GB modules (a configuration that isn't officially supported on that motherboard), you may have to increase the memory and the northbridge voltages a bit.

tanks a lot

I run memtest about 1 hour( 1 PASS , 0 ERR.)

this is

Other than the RAM upgrade, anything else was done? Do you have the issue if you run 4 GB instead of 8 GB?

 

[erosalex]

before update RAM absolutely 0 problem, nothing. With only 2 stiks (4Gb) the problem is the same

 

[GhislainG]

What RAM was installed before?

 

[erosalex]

dimm A1 and A2 corsair 800 MHz XMS2 4 4 4
dimm B1 and B2 buffalo select 800 MHz cl 5

I think not in dual channel, but anything problem with this 4 x 1 Gb

 

[GhislainG]

You are correct; they probably didn't run in dual channel mode. Can you reintall the old modules to make 100% sure that the problem doesn't occur? I presume that the old modules are single-sided (8 chips) while the new ones are double-sided (16 chips).

If you can't reinstall the old modules, check the memory voltage and the northbridge voltage.

 

[erosalex]

the corsair is double sided

I think to try a flash bios to latest version

 

[GhislainG]

That might help, but don't do it from Windows.

 

[erosalex]

YEEES, this is the way

PC is stabilised, the screeo on CPU-Z is the same

all warks properly;
tanks a lot

I have a maximum of performance for this configuration?

 

[GhislainG]

You have better performance only when your system uses more than 4 GB of memory.
