These settings would not post (a reset cycle). (one time it did post but freeze on the gigabyte logo boot screen)

1 stick will do the same at 1066.

(Settings and test results at 800: http://forums.tweaktown.com/f69/ep45...tml#post331745) this produce a pass on DDR 800 but a boot up issue...

Good luck and let me know if you need any thing else

Re: EP45-DS3L Dual Ch. RAM Issue

Try this, from your above settings. Since you are not overclocking right now lets leave the vcore alone/auto so you are sure that is not the cause

Re: EP45-DS3L Dual Ch. RAM Issue

Slots 2+4 act the same? Just wondering since you mentioned the slots.

Did you check your ram voltage in PC Health section to see what is applied when you set what?

Well continue you tests, then if you want please try these settings for 333 FSB

OK< before you get into these I made some MCH Ref suggestions. In my signature you will find a link to a small guide I made on setting this. Please read that guide and try a few changes with your above settings as well before you get into trying with 333 FSB. MCH Ref can be the key to stability sometimes and since you already have to lower your MCH this may mean your MCH Ref is getting to be set way wrong as well. MCH Ref and Vtt are connected, so you will need to set your own Vtt. Just check out the guide and if you want try MCH Ref .68-.80 with various Vtt amounts such as 1.20-1.32
