ASUS Maximus II Formula - new P45 king?

[Grnfinger]

Hello everybody. I finished assembling my rig and am running @4.27Ghz, and am very appreciative of all the time people have spent on this thread. My goal is 5Ghzbut I will settle for the max of this board which will probably be the limiting component.
I did have a question - I haven't found a solution to stopping the clock speed throttling. When I run CPU-Z, it shows my multi at 6 and my Core Speed as 2550, but my multi is set at 10 and my Core Speed is 4250(I can see it flipping back and forth on CPU-Z). I thought it might be ACPI and set it to disabled in Bios, but it wouldn't boot, so I had to re-enable it. I see everyone who posts cpu-z screens has their top cpu speed showing so I must be missing something. Any ideas?

Thanks

Disable speed step/c1e in bios

[Hansfragger]

Thanks - Your awesome!

Try setting Clock Skew to 300ps it will help to get the ram stable
Also relax the timing a tad and it should settle down.

Thanks for advice. I'm assuming the DRAM clock skew right? change all channels to delay 300ps or advance 300ps?

Sorry I should have been more clear.
Set Dram Clock Skew to advanced 300ps what ever channels your running ram in.

Double post alert......

Not killer bandwidth but I'm happy with the final results....

[zlojack]

Nice work Grn.

[SiGfever]

I am still working on my overclock but here is where I am with the memory so far, I know it ain't much but it is a work in progress.

[Grnfinger]

Nice work Grn.

Thanks my friend

Hey folks,
I'm considering this board for my htpc, with a Q9550 (slightly oc).

My questions is:
1) it is stable with this cpu? If so, which bios? I dont want to see a bsod with lenses.
2) The extra sata ports can be used for a dvd and the boot drive? I need all 6 intel ports for my storage.

This board works very well with the Q9550 and you can OC the 9550 easily to around 3.7GHz with everything pretty much stock 3.8 if your chip is decent.(of course 4GHz is doable 24/7 also but voltages get a tad high)
The only thing I noticed is some ram modules cant handle all the dividers available on this board.
Bios 1307 seems very stable
I'm not sure about the Sata ports

CPU Clock skew or NB clock skew?

Well, bit of a stupid question but is that really a C0 what you have there?
Im running the same clock with the same ram speed and timings and i got lot slower L2 cache results.
Dont know that got to do with the motherboard or the cpu differnce.

Yes.

[Grnfinger]

After some fine tuning this is what I'm settling on

Seems the G.Skils are not up to the task of 1132MHz so running Mushkins XP-2's

[radaja]

this is the best ican do with my memory. iwas able to get 4100 w/memory running 1/1divider,but when itry 5/6 i have to back down fsb.my mem is rated at 1100, i just cant seem to get it to run past 1090.any help would be greatly appreciated. ive tried raising myvfsb 1 notch, myvnb 1 notch, my vcore and still not ablr to get it prime stable. here are my settings

[nugzo]

I'm still having blend issues. Lowered mem to 930, removed 2 sticks, up voltages, lowered voltages, ran many memtest runs with no errors, changed dram skew as advised, loosened all timings..... primary timings relaxed to 6-6-6-15, lowered all subtimings by 1 number, still failing blend. not instantly now like before but within 10 minutes. And the memory benchies ar horrible compared to my 780i. My read scores were almost double with the 780i.... Makes me want to order another Striker II Formula. Oh well i'll keep trying whats advised and keep playing and reading. I have soo many settings on auto that i'm sure i'm missing something. Is there an OC handbook per say like i had with the nforce chipsets? where each individual bios setting is explained in detail with positive and negative effects towards your OC and system stabilty? If so please link me!!!!

[CryptiK]

@ Grnfinger - nice work, that is quite respectable for 24/7 setting

@ Nugzo - What vNB are you using? Do you have static read control or read training enabled? 1.28v vNB should be fine for DDR2-1100, and disable the two options I mentioned if you have them enabled.

I would suggest this for 1100MHz

And add a few drops of dram juice

Those work for my CL5D's upto 1120 MHz with 2.1 volts
Also your NB volts look really low imo for what your trying to accomplish

@ Grnfinger - nice work, that is quite respectable for 24/7 setting

Thanks

[radaja]

@grnfinger,this new setup i have is real picky about what volt i can give it. for instance it seem i dont have any headroom where volts(vfsb&vnb) are concerned the only stable setting seems to be vfsb 1.14- 1.16, vnb1.16-1.20 any deviation results in prime failing within the first 2 minutes or bsod or windows lockup. i just trid 9x439 w/ mem 1101 and no boot, ive also been trying 6x485-500 w/vfsb 1.14-1.16 and vnb 1.16- 1.30 no luck. its really depressing to be so limited (9x449 w/ mem at 1080 5/6). my previous g.skill 8500 out performed this new 8800 set.

[CryptiK]

Can you run 1.20 vFSB & 1.25v vNB together? Your voltage limitation is a strange issue. Do you have any other ram you can use to try things out?

[radaja]

@cryptik ill give it a try. no to the ram , im going to get a new set any suggestions ,also would 2x1 kit be better for over clocking.UPDATE just tried 1.2 and 1.25 failed prime within 1 second tried 1.24 vfsb 1.25 vnb failed after 45 seconds

[CryptiK]

Yeah a 2 x 1GB micron D9 based ram kit would be better for overclocking but not so good for longevity. My CellShock PC8000 CL4 GKX kits are nice though. The best 2 x 2GB ram kit available today is the G.Skill 9600 PI kit, they do 650+ MHz.

[radaja]

where can i find those team extreme or cellshocks that you have there

[dawdaw]

Hi everyone, Thanks for all the feedbacks and advices you provide in this thread, really great job guys especially CryptiK . well i'm interested in getting the M2F and i dunno whether i should get it now or wait till it hits the shelves with the P45 Rev A3 in? and is it that reliable or it does suffer from the same P5Q D problems, if i get it now what Bios do u suggest, Thanks again !
