Asus P5N-E SLI/OCZ2N1066SR2GK/Q6600 Probs

Have you tried booting with a single stick ?

Yes I have and it boots up and then swapped sticks and it booted again but put 2 in and beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep and no boot know what I mean

If it boots with one stick go into the bios and set the memory voltage and timings manually, then try with 2 sticks.

If the above doesn't work...

Did you check to see if there is a new version of BIOS? I remember people complaining about the same deal with the P5Q-E (I used Gskill and worked first try when I built my system). Either an updated BIOS or new sticks seemed to do the trick for that sucker.

Gooday been flat out lately, only just got to it and you are a wizard man, I am not gonna mess with the BIOS coz if it aint broke dont fix it,SLI works fine and I am blown out by how quick it opens windows now23-25 seconds from start.Now tomorrow and the overclocking and................well you know,BTW Thanks heaps and cheers
