    This is probably as good as it get for me..... Maybe 50 more mhz, but thats it... Not posted here, but SuperPi 1M is back down to 11.5 seconds w/ 2 x 2gb of DDR800 ;)

    Set it to auto then >>>

    Why 544-12 at 840? Did it fail at 444-12? Hmm, have you tested maybe tRD 8 again, but with a bit more MCH

    It didn't fail anything... except the BSOD issue we've been PM'ing about.

    I loosened up the ram a touch to see what would happen.

    On the MCH... my buddy has the board clocked to the max and has yet to go over 1.1v, so I thought 1.2v would cover me.

    I'm taking any tweaks slowly since this beast is stable all around at 3.99Ghz right now.

    Edited post #71.... Back to 4.038ghz 24 hour Prime 95 stable and all around stable with graphics apps. as well.

    I'm not sure what exact change made it more stable, but I'm going to try 4-4-4-12 again instead of 5-4-4-12 where I am currently stable as a rock. After that back to Static Tread of 8 possibly.

    From there I'll drop down on the Vcore although temps are not an issue at all on WC'ing.

    14+ hrs. P95 @ 4.1ghz and still going. Relaxed timings to 5-5-5-15. Everything else is the same...... and I got my best SuperPi 1m time at this setting- 11.36 sec.

    E8500 @ 4.1ghz

    28 hrs. stable enough? ;) Rock solid here w/ 11.36 SuperPi 1M times at loose timings. I may try to get it to 4-4-4-12 at 4.1ghz, but my G.Skill will probably not play.

    LSD- Why doesn't Gigabyte put memory dividers on these boards? The BIOS only allows you to run 1:1 or higher with the memory. I could use a 5:4 or 6:5 FSB to memory divider.

    Sure would be cause for a bios update for me if you added that setting like most other boards have ;)

    WHAT? You can use all of these memory dividers >>>



    If MCH is manually set you will only see the available ones per that set, if MCH is in Auto you would see them all with thier respective letters.

    But anyway, ANY/ALL Straps have more then 2.00 (1:1) available, why do you say you only see 2.00?

    I'd like to run my memory LESS than 2.00......

    I think having to run memory 1:1 or MORE limits my overclock. I don't see any way in the bios to run my memory less than 1:1.

    ie.... say I want to run 500fsb- with this BIOS I don't see how I can run my memory at DDR800?? See where I'm coming from? I have to run my memory at DDR1000 with any MCH/NB setting if I go to 500fsb.

    2.00 is the lowest setting available on any strap. How about a 1.25, 1.5 and a 1.75 setting? At 1.25 I could run 500FSB and have my memory at DDR800. No more memory tweaking issues and I could clock the heck out of my chip without stressing my memory and having to overvolt that as well and play with timings.

    I'd love to keep tight memory timings with my CPU at it full potential.
