Good luck, let us know how it goes!

I unlinked my memory speed and set it to the same speed as my FSB and it's stress testing like a charm.

EDIT: Slowly cranking up the FSB. At 462.5 FSB at the moment. Increasing FSB after every 10 passes of 4GB LinX.

Edit #2: 29/250 4GB size LinX passes @ 3.7 GHz for now. Testing overnight. smile.gif

Bumping my own thread to request more help.

Anyways, I left LinX running overnight with 4GB problem sizes and it ran 100+ successful passes without any errors. However, running Prime95 (blend test) for a few hours ended up locking up my computer. Would this indicate that my memory isn't stable?

My memory voltage was at 1.9V but is now at 2.0V (skipped 1.95V) as of the following screenshot.

Have you bumped up your NB voltage to compensate for the amount of Ram sticks you have installed?
I had to take mine from 1.1v to 1.2v to increase stability.. 8gb puts alot of stress on the NB.
What are the NB temps aswell?
My 9400 is running @ 3.4ghz with 1.264v at 100% load, this is ofcourse with LLC enabled as i found disabling it needed a higher vcore to be stable for the simplest of stability tests.
However im running it on a UD3R board compared to your 780i.
