Q6700, P5Q-E... 500 fsb quad

[prime81]

0605 currently... it's what was on the board when i got it.

This board could be the next P5K, if they can fix the PL issues.

That is the whole secret right there. It's a trade up. You could tell from the everest bandwidth tests how loose the PL is. As you can see from the ss below, I get better RAM bandwidth at 7x500 on X38 than he does with the p45 at 8x500 at the same frequency even with 5-5-5 timings.

i beg to differ, only 1:1 strap is truly f'd.

pl8 is do-able w/ 500fsb

however latency is not as nice

Lowest stable PL I could do with 500fsb/1:1 is 10, not terrible but could be better.

Show me 500 fsb, 1:1, PL8. Cos if I change strap, then I could PL7 on x38. Also, doesn't that dualie act differnt on strap?

As far as CPU PLL volts... what would be recommended? Is this voltage bound to same regulation as the vcore itself of 1.55 max?

Thats a no boot mate on current Asus lineup... also one of the reasons why X48 and co remain the high end enthousiast boards... but I'm pretty happy to have traded my Formula SE for this easy to setup mobo... I was so tired of all the overvolting on the X38 and instability issues... Yesterday we tried a new formula with some 9600 sticks and 4870 crossfire setup... we just couldn't get it to post stable with the Qx at 4.5.., let alone get into windows... reverting back to an older bios solved most of our issues... and really bandwith is not all that matters for most... stability is... pretty hard to find for normal users on X38/48... the learning curve from previous Intel chipsets was too big for many... and many reverted back to P35 or previous generations... P45 is easy to setup but it get's tricky at high FSB too...

I would love to see your numbers too on P45... but hardly think it will be possible... like you said it's all about compromises...

Here is mine with 1200mhz DDR2, PL8..

Hey guys, could you put ur BIOS config plz? I´m trying to get stable @500 and can´t. Thanks

i was able to do it on q6600 and e8500... and that is actually pl7 (8 w/ pullins enabled, setting directly to 7 however results in no post) stability wise i found that 333 strap worked the best.

as i said before 1:1 is currently f'ed, changing the strap however allows better pl and faster ram. now conversely, really high fsb gives a nice bandwidth and latency that i could not achieve on x38 and x48 due to fsb limitation. 1:1 strap really starts to shine @ 550+ fsb. i guess i should re-rest on x38 and x48 when i get home as my previous maximus was fsb limited to 530ish. i can check 550fsb + pl7 (or 6 w/ cas4) to see where highfsb + pl start to make heavy gains. its going to take another week to sort through my dfi bios again to test this i must have been high and not uploaded the screen shots to photobucket...

Not hardly ... just had to adjust my PL to 8 for 7 x 500. By default the p45 loosens timings to get things stable. I had a Maximus Formula SE flashed to Rampage before this board, and I gotta admit this p5q-e is faster.

where do i find this 'PL' setting?

where do i find this 'PL' setting?

performance Level, usually under transbooster settings.

AI Transaction Booster: MANUAL

My new baby will be here wednesday... picked up a new retail qx9650 fer $750.

Which BIOS are you guys using with the -E? Have one coming in today with a Q6600.
