To run twister on strong or higher you will require alittle more NB juice then your 1.29voltsQuote:

I require 1.39vNB for 1130MHz running 471x8.5 on 333 strap
DRAM Static Read Control: Enabled
Dram Read Training : Enabled
MEM OC Charger : Disabled
Ai Clock Twister : Stronger
Transaction Booster : Manual
Common Performance Level [8]
Why is that?Quote:

it's a great board, I love it!
It doesn't leave you much room for selection of an appropriate ram speed, for most people, you're stuck with 1:1.Quote:

eh, 1:1 is really all i need... i really only play warhammer. but now when i get my SS fired up and ready to rock im definetally going to be switching it up some.
I can't game on this board with 500+ FSB, as it makes the games play in fast forward, even the menus etc run at super speed and its ridiculously unplayable. For example if I play a Need for Speed title, the cars take off at what looks like 600 KM/H and you crash almost immediately. it does not matter what multiplier or divider i choose, and changing every setting does not prevent it from happening. At 499 FSB or less its ok. That is also one of my reasons for using a sub 500 FSB setting. BTW my P5Q-Deluxe did the same thing, i think it may be a P45 'feature' lol.
Wow. Would never have thought that it makes such huge differences.Quote:

Seriously if i made a video of the games when it does it you'd laugh your ass off its so fast. Not 'awesome you have high frame rates' fast, but 'stupidly ridiculous unplayable something is definitely wrong' fast.
Sorry for the double post, but could someone with a quad (9650 or 9770) please do a max stable FSB test on this mobo using a lower multiplier? I'm very curious to know what it can achieve.
EDIT - I mean stable as in preferably SPI32M stable, but 3D stable, 1M stable, whatever, just post it up.
It all depends on your ram and specific oc. Mine can't do 1200mhz, in conjunction with my oc, i'm stuck @ 1:1.Quote:

What sticks do you have XP2-8500 ?Quote:

My Dominators will do 1225MHz @ 2.2volts but sadly there only a 2x1GB kit.
2x2gb redlines reaching 1200mhz? :confused:Quote:

If i was to go with 2x1gb, i would stick with my Cellshock pc8000 which could do 1260, but vista and 2gb is a no go... :p:
I havent seen any hard proof and cant recall what forum the claim was made on .Quote:

Can anyone get the 1:2 divider working? I cannot get it to even boot using 1:2 divider no matter what voltages/PL etc I set. I think the divider is broken. I'm using BIOS 1307, I've tried the older BIOSES and the 1:2 divider is broken on those too.
I can boot at 650 - 700+ MHz on the ram on the 2:3 divider.
Here we are friends of mercy :D Tha same as you Cryptic : gat a lot of DDR2 to test on this board and nothin' over 650 at this time !! Yuc!!
Some GEIL PC8500 are comin', so I'll try to push them up over 700, even with the Commando which is with them ;)
A question about Crossfire please :
Gat a 4870 and a 4850, so want to test Crossfire, but nothing happen when I enable it in the CCC
Is it real that I should put the 4870 on the second slot, plug the screen there and put the second GPU on the first slot ??
Something to change in the bios too : PEG/PCI or PCI/PEG ??
Don't know how to do and even thought gat to change the way of installing my rads to one or other configuration...
That's why I'm asking cus' I don't want to waste any time whith this rads installation :D
EDIT : So it was that :D to get the CrossX I must put the 4870 in the second slot and the 4850 in the first (we should know that ;))
That's nice !!! Tryin' to bench 3D harder now !! @3,6 2k more for 3DM05 & even better at 06 ^^
Sorry I can't help you with the crossfire issue.
About the divider problem, have you ever got the board to boot/run with the 1:2 divider?
I have got 666 MHz on the 2:3 divider, but nothing I do will get the board to boot with 1:2.
this is really annoying ...Quote:

Even if I increase vdimm to 2.33v, it does nothing for stability at 666 MHz. I have tried altering NB DDR Ref voltage & DDR2 Channel A/B Ref Voltage up to +150mv & -100mv with no differences observed in stability at max bootable speed (666 MHz) and no increase in max bootable speed.
I think there should be a ram driving strength setting to assist stabilize high ram clocks. I think the option 'ram OC charger' is a drive strength setting (but it can only be enabled or disabled, which is too coarse & perhaps enabled is not strong enough), as I cannot load windows at more than 605 MHz with it disabled. This has never been confirmed by anyone though, it's just my personal speculation.
I have finally gotten my rig stable @ 4ghz! Vcore @1.352 mem 400mhz strap @ 942 mghz.
Q9550 2.83 ghz @ 4.02 ghz
4 x 1GB Patriot DDR2 1200
All voltages on auto except Vcore and mem. meme is set to 2.0 volts. Loadline enabled and all spread spectrums disabled. Speed stepping enabled. 18888 marks on 3dmark 2006 and 12999 GPU score on 3D mark vantage. Intel burn test stable with 100 passes. Prime 95 stable 8 hours. I think its good to go.
Throwing all the games I have at it now it now to make sure it is reliable.
