No matter what, I can't get my OCZ PC4800 RAM (
http://www.newegg.com/Product/Product.a ... 6820227217) to run at stocks speeds

I'm wondering if it just isn't isn't working well with my mem controller on my Opty. A guy from OCZ has been trying to help on Anandtech but no luck so far. I'm going try with my new Opty when I get it on Monday and if it doesn't work out I amy sell these sticks and get some Corsairs. My Corsair 3200's worked awesome. You think they'd AT LEAST run stable at rated speeds (600mhz 2.5 4 4 10)
Here is what I have tried with the 704-2BT bios @ 2.7, 2.8, 2.9 & 3v...(items in parentheses are other settings tried).
