    Made 2 main changes, MCH Core to 1.38V, also upped MCH Ref, it's now only about 1 notch below CPU Ref.





    And for comparison, Arctic-k20's same IBT.

    http://forums.tweaktown.com/f69/ep45...tml#post344258

    EDIT: Tried Performance Level 9 using memset, but it froze my machine.

    EDIT2: Ran IBT again with above settings, only thing changed was Performance Enhance in BIOS set to Turbo.



    Appears to be about .4 GFLOPS increase.

    Did you try setting tRD = 9 in the bios? This might work when using the 2.00D memory multiplier.
    With 8GB of memory, tRD = 9 might not be stable with 500MHz FSB.
    Additional tweaks with MCH Ref and CPU Ref might be needed.

    Obviousely in the first run tRD is disabled and the second it's 10, avoid the turbo, set it manually.

    9 in BIOS won't post. I have not tried 2.00D yet, I'll try this later and get back to you.

    The number in BIOS do not mean anything, use those that give the best performance.

    2.00D would not post. Here's some benches with my current config.

    Slight update, after some more consideration, I chose to go to my 9.5x444(4.21GHz) template, for long term use. I wasn't happy with having to keep my VCORE and CPU termination so high, for long term use.

    My 4.21 template has now been modified, and tested 12 hours blend stable; also tested it's performance in IBT and the gflops look right.



    Something interesting to note, looks like my 421 OC has higher memory read, and higher L1 and L2 cache performance. However, my 421 is using 8 tRead, vs 10 tRead on my 8x500 (4.0GHz).

    Something else I noticed, it seems like you can't use as low tRead values if your system is running 1:1, seems like too much strain. This is probably common sense to most people, but I just found it interesting. (Which MAY mean if I ran my 8x500 template at something a little different, possibly a tad lower but at 5:6 ratio, I may have been able to use a lower tRead value - something I may experiment with in the future)

    And just for the record, I couldn't get the tRead values any lower than the values I listed. The tRead for the Turbo setting in BIOS (while value set to AUTO) seems to be the lowest stable available.

    P.S. The graphics corruption problem that I posted about earlier seemed to be a widely known issue with the 5700 and to a lesser extent 5800 series cards. A driver update may solve this problem, but I didn't have luck with it. It hasn't been verified if this problem is purely software related, or of faulty hardware/overheating may also have an impact.

    Yes, but......with some qualifications.
    Your statement applies with high FSB speeds.
    With 420 - 450MHz FSB, tRD = 8 or 9, and a 1:1 memory ratio is often stable.
    With 400 - 420MHz FSB, tRD = 7 or 8, and a 1:1 memory ratio is often stable.

    An interesting read is AnandTech's ASUS ROG Rampage Formula: Why we were wrong about the Intel X48 review that deals with memory straps, timings and related bios settings. Reading and understanding pages 4 - 10 qualifies you for a masters' degree in DDR2 memory configuration.

    Page 4: The Basics of Strap Selections, Dividers and Derived Memory Speeds
    Page 5: The Clock Crossing Procedure and MCH Read Delay (tRD
    Page 6: MCH Read Delay Scaling and Default tRD Settings for Each Strap
    Page 7: Real-World Results: What Does a Lower tRD Really Provide?
    Page 8: The Rules of Working with tRD: What's Allowed and What Isn't
    Page 9: How to Choose an Appropriate Memory Configuration
    Page 10: Conclusions and Final Thoughts

    Page 8 has a formula that lets you mathematically test potential configurations.

    Another good read is AnandTech: Gigabyte GA-EP45-UD3P - P45 at its Finest review.

    Here are some general 400+ MHz P45 tRD guidelines using 4GB of DDR2 memory:

    • tRD = 7, 2.00 or 2.40 B-memory strap is stable up to about 420MHz
    • tRD = 8, 2.00 or 2.40 B-memory strap is stable up to about 460MHz
    • The D-memory strap requires tRD to be 1 step higher than the stable B-strap setting up to about 470MHz.
    • With ~480MHz or higher FSB, the D-memory strap usually can be set 1 step lower the B-memory strap.

    P35, X38, and X48 motherboards use different chipsets so there will be some differences. As always, YMMV.

    My 2x2GB setup is stable using:
    492 FSB (7x492 = 3.44GHz)
    984MHz memory @ 5-5-4-12 with tRD = 9

    I'm sure that others would benefit if you posted your final (for now) bios template, "standard" settings screen-shot, and several benchmark windows.

    Thank you for this goldmine of information, will be some good reading for later. I'll post the 4.21GHz template along with some screenshots after I get some Zs.

    I Appreciate your input as always!
