So i have to buy a sandy bridge cpu to even for my ivy cpu to work on this motherboard?
If that's the problem (it's makes the most sense), then yes.
Every Asus Z68 board I've seen that has an Ivy CPU installed without a BIOS flash first always presents with the MemOK light lit. I don't know why, but it's always the case.
Edit: I read back through your previous posts and they were about Z77 boards. Why
didn't you get a Z77 board if you knew you would be getting a 3770K?
Incompatible RAM could still be a
very remote possibility, but it's more likely that, if it's the RAM, the RAM is just simply bad. Vengeance is compatible with almost everything (and certainly Asus boards). An incompatible CPU is what I
really think it is, though.
It
might be worth it to just return the Z68 board and get a Z77 board...
