Gigabyte GA-EP45-DS3 and F2-8500CL5D-GBPK unstable

[Touffe]

Hello,

Sorry for my english, but I'm french.

Here is my problem :

Mother board : Gigabyte GA-EP45-DS3 (bios F9)
RAM : F2-8500CL5D-2GBPK
CPU : E8400
OS : Vista 64

My PC is unstable (blue screen) and CPU Stress MT find errors after 1 or 2 mn running.
I tried default bios settings and also to set manualy RAM settings. It does not work.
I tried to set Ram Vcore to 2.1V. It does not work too.

I'have seen on your website that you qualified my model of mother board with my model of RAM. Here is the webpage.
Could tell me what were your settings ?

Thanks a lot.

I already did it :

I set my ram at 1066 MHz, 5-5-5-15, 2.1V (as mentioned in the thread)

Is there other settings to do ?

[G.SKILL]

we don't have other settings
would you like to test one stick at one time?
thanks

OK, I will do it and I will post my bios settings.
May be I make a mystake.

[G.SKILL]

thanks
we'll wait for your testing

Here are my bios settings.
I'll test one stick at one time in a few hours and send the results.

are these setting default?
if not, please keep them default

and try to set the MCH voltage:

and please try to test one stick at one time to check if there is one defective
Thanks

are default settings

I tested one stick at one time on differrent slots and they are both OK (CPU Stress MT and memory test of Vista at reboot)
I tested again quickly the 2 sticks together and it seems to work fine now...
I don't understand. I only removed and put them in the slots.
I will test it strong again and give you the results.

Just a question : how does the MCH core influences the good work of memory sticks ?

[G.SKILL]

adding MCH voltage would improve the stability of memory controller of northbridge
if your issue is solved, it may be caused by installing not properly
thanks

Here are the result of some new tests :

1 stick on slot 1 => OK
1 stick on slot 3 => OK
2 sticks on slots 1 & 3 => KO
2 sticks on slots 2 & 4 => OK

thanks for updating the info
