ASUS Maximus II Formula - new P45 king?

[humeyboy]

@ Grnfinger, I'm kinda temp (I hope) stuck @ 475FSB on lowish voltages for now.

Did you state before latest Bios was bad for you and that 1307 and 1901 are better ?

Thanks for the info the other day, but until I got NB GTL sorted out I could not even do 425FSB stable no matter what.

I could boot into Windows at 490FSB with high voltages though but now its all stable at 475FSB mainly due to the NB GTL.

I found out my set up needs Positive values on the NB (Minus wont boot at current clocks) so set the CPU GTL's to Positive also (seemed ok at Minus but I assume best to keep in line with NB.

[In-Fluence]

Cheers, I'll get to work on detailed timings & stuff after I get a few more of the other setings tuned. There's definitely a few timings I could drop down by 1 or more which might hopefully bump the speeds up a touch. I'm still testing my NB GTLs at the moment, (seemingly at the same stage as Humeyboy seems like negative ones are working better for me. I've done all the way up to +80 with +20 being the best one, that is until I went negative, so far -15 has more than doubled stability time for me, but still plenty to go!
Humeyboy - I think you should stick with the positive CPU GTLs you had in the 1st place. I'm no expert on this level of o/cing, but I'm pretty certain adjusting them to match your NB isn't the way to go. I'm finding that sticking with my tuned CPU GTLs (which are +40,0,+40,0) prevented reboots, and has given me consistent results when moving on to tune up the NB GTL. Of course it might be a completely different story with your 45nm chip...just my 2p Good luck with it!

My PC is empty at the moment since I'm waiting for my Q9650 to arrive so I took the opportunity to remove the motherboard heatsink and replace the crap that ASUS put on with my Zalman thermal paste. I was getting NB/SB temps of 45-48C with everything at stock so hopefully that'll improve. What sort of chipset temps are you guys getting, particularly those of you who have replaced the TIM with something better?

I found 1901 to be a very good bios, I honestly have not played with NB gtls much maybe I should give it try.
When I first got the board I ran my CPU GTLs at a positive value and it worked for me with a Q9550, then when the GTL calculator came out I went with a negative value and its still stable so I don't know

I removed my complete stock cooling and replaced TIM with AS5, my NB is on water running 1.45vNB and I'm sitting at a cool 37c idle, single loop with a Q9650/4870X2/NB 120.3 rad

[humeyboy]

Yea minus or positive on CPU GTL's is kind of the same for me but not for the NB, its currently +40 (worked out on calc, -40 will not even post).

I will try CPU all -40 and NB +40 (they are same since both 45nm and I have voltages the same for VTT and NB.

[Ghostleader]

With all my LGA 775 board I need diffrent NB GTL depends on if I run dual or quad (45nm).

With a quad I need something between auto and +80, I can be stable with LinX and Prime95 blend but Crysis fail, Crysis need between +60 and +80 to be happy and I´m stable with all three around the same.

With a dual I need something between auto and -60

Of course above is depended on which bus speed and VTT value, with a quad is like higher bus speed and higher VTT volt, more at the +, with a dual it´s the other way around.

Please share your results, I'm interested in testing out NB gtl's, I'm going to power up the MIIF this weekend

[humeyboy]

Well it wont boot with 475FSB with the CPU GTL's @ -40 with the NB GTL @ +40.

I thought I had 480 FSB today but it froze, seem many get stuck at about 475 FSB on Quads.

I am on the latest (not necessary the best) Bios though, I may try 1307 and 1901 and then contact Asus and try get some support.

I ain't 100% sure if my settings are the best/lowest they can be but I'm 100% stable at 475FSB with 8GB.

Where do I get a blank template ? (I need print it out to fill in info while in Bios).

[CryptiK]

Just copy and paste a filled out template into Microsoft Word and erase all the values, then print that out.

[humeyboy]

Thanks but I'm 100% stable with my above settings at 475mhz.

Its trying to get above this that's an issue, I have tried more voltage but it does not help, must need mess with some other settings or try older Bios.

NB will not let PC even post the Bios with -settings above speeds.

Hmmm, a bit strange that you guys get that to work, I thought that around this worked for a 45nm dual

CPU GTL Reference (0): +40mv
CPU GTL Reference (1): auto
CPU GTL Reference (2): auto
CPU GTL Reference (3): auto

and around this for a 45nm quad

CPU GTL Reference (0): auto
CPU GTL Reference (1): -40mv
CPU GTL Reference (2): auto
CPU GTL Reference (3): -40mv

and I thought that default value is this

I understood you are stable at 475 FSB, I meant when you go for 475 - 500 FSB, they are the settings you will most likely need to alter. vNB will especially need to be adjusted as you are also running 8GB ram.

[kamieldehond]

im trying to get 4x1gb D9GMH stable on this bord. Atm i have it at 562.5MHz with a divider of 4:5, but i want them at 600+ MHz. Anybody here has 4 ram sticks running at 600+ here on this board?

If so what are your settings?

[In-Fluence]

Increasing the TRFC memory timing is supposed to help a lot with 4 sticks, have you tried vaues over 50?

havent tried that yet. will try it when im done rebuilding my pc

thx for the advice

[Grnfinger]

Just setup the MIIF ran a quick run using Humeyboy's NB GTL settings, will test more today, NB GTL's seem to play a huge roll in high FSB Stability

My NB GTL ain't +40 just by luck, its due to me doing the same calculation as you do for CPU GTL's, its a 45nm Chipset so same formula applies

I think at 1.4108v NB your NB GTL would work out more than +40 (Will it even post at -40 ?)

Seems a tad higher volts esp as not 1:1 but that could be as your on Stronger and 8.

Also for now (not perm) lower to Moderate and 10 to see if you can get more FSB and try it on 1:1

[Grnfinger]

I'm fine tuning settings now, +40 was a base to start cause of your template....
looking for 475 to 480

Have not tried a negative NB GTL value yet, will test this later today and see if it will post

Calculating it will give you a ballpark and a starting point. However experimentation will show the best GTL setting for and particular FSB, divider, and other hardware combination.

[Grnfinger]

Negative NB GTL's will allow my rig to post untill I go below -30 anything lower will not post.....

475x9 @ 1140MHz ram the chip is stable but the ram craps out on IBT guess thats the max for my GSkill 8800 kit, testing my other kits of ram currently
Adjusting NB GTL's from +40 all the way to +80 has no effect on stability at 475FSB setting to +30 and IBT fails

[kwalker]

Nice clocks with that 9650 and decent bandwith

My 9550 settings for 24/7 are with gtl's at auto.
there are a few settings a tad on the high side.... pll, northbridge ,and vtt but Its what I found most reliable running VMserver with two Ubuntu installs folding non stop.
I can do anything I need or want except playing Crysis at the same time
The settings haven't changed for 7 months except 8 gig of gskills @ 1100/1.85 volts. and I haven't smoked a component as of yet

[DonNiger]

Sorry for asking but there are150 pages .....
Is it a good board for OC? For dual and quad cores. Is it better than TPower for duals?

[Grnfinger]

very good board for dual core CPU, quads are harder to overclock on this board
cant comment on TPower board cause I dont own one but I think most boards are better than the TPower
