Check out this thread
It's a bit complicated so here's a post by me helping another member understand how to test the lanes.
I really need to quit putting off making a thread on GTL lane adjustments......
Could you please find the correct link for the 2nd link there, it just takes me back to OCN's front page.
*EDIT* Ok, so I read the EVGA thread, and I think
I know what I'm doing, but not completely sure.
He said a FSB voltage of 1.2 should take you to at least 400 (which is what I am trying to accomplish right now), so I downed my FSB to 1.2v. Also, since I'm upping my CPU from 3.0 to 3.2 GHz, I upped the voltage from 1.343 to 1.39 I believe, to make sure I'm getting enough voltage.
I set all the GTL lanes to +50, and I'm booted right now at 3.2 GHz (FSB of 1600) with Linked & Synced RAM running at 800 MHz.
So now, I guess I am supposed to run Prime 95 (how long?) til the core(s) fail(s), and then continue to increase the GTL lanes by 5 or 10 until I can run Prime95 stable. Record these numbers.
Then I continue to keep adding 5 mV until the core(s) fail(s) in prime95 again. Record these numbers. Then I find the mid point (rounded up) between the 2 recorded GTL values, and thats my final GTL value.
And after all of that is done, I guess I should try lowering my CPU voltage as running Prime95 to find the lowest, yet still stable, voltage possible. Correct?Edited by RapidFireGT - 9/18/09 at 11:11pm
