ASUS Maximus II Formula - new P45 king?

[CryptiK]

Of course this is the most annoying bug...

My board is capable of doing up to 0.15 VNB-VTT. Should i consider myself lucky...?
Have u tried higher than 101mhz?

Yes I hate this problem, when I need higher vNB to bench SPI32M, it always locks on reboot, then turns itself of, and reboots and hangs. After a power off reset, BIOS has been cleared. If I set 1.25 Vtt I can use up to 1.40 vNB, but my cpu does not like high Vtt, and makes it unstable needing more vcore and GTL tweaking to be stable, I can run 4GHz stable on 1.10 Vtt. I needed more vNB to be stable, but to raise vNB I had to raise Vtt, which made the CPU unstable. This problem almost ruins the board. and seems to be restricted to the M2F, boards from Gigabyte, DFI etc don't do this. Only Quad users seem unaffected as they run around 1.25 - 1.4 Vtt anyway.

I did once try higher, I can't remember what it was, I think it was 103, and it refused to POST.

New personal best O3 run, after tweeking cpu/nb GTL's.....

Nice score, those cards pack a punch when run in crossfire.

My latest results. The temps you see to the far right for Everest Ultimate are under full load of Prime95. The screen shot was taken under full load so the appropriate voltages, speeds and temps would be shown since I have speed step and enchanced C1 enabled.

Hey mate can you try to lower those VTT and PLL are way too high for an E0...I think your chip can do it with less

Just a though

Finaly, i got 1200=)
But i had to choose 1200 from the list, only thing i did and turned up the memvolt.
But one thing i saw, that was bios did sett up the vcore. The only thing i did was to set 1200 and more memvolt.
Have to find out what the mobo like and dont like.

heres another area where the maxII is falling behind the newer p45 boards. when i got my UD3P i was shocked to find out that at 500fsb 1/1divider it was able to use pl9. now i just saw pangingIII is able to run pl8 1/1 all the way up to 519fsb

Hi everyone,
I replaced mobo P5K-Premium with Maximus II Formula last week and met a weird issue on OC with bios1702&1602. I could set my Q6600 to 400*8 by 0901bios and the system is quite stable. In POST, it shows Q6600@3.2G. Under 1702or1602bios, I use same setting as 0901. But in POST it shows Q6600@3.6G, CPUZ shows 400*9 as well. Maybe this make the system unstable. It could be blue screen, or hang at DET DRAM after reboot. It shows overclock fail after I shut down the power and reboot again.
Is this a bug for new bios or the mobo defected?

[The Water Dog]

you get only multi.9 with bios 1702 and 1602
A big ugly bug.

[radaja]

oh i thought on the maxII we could only go as low as pl10 at 500fsb 1/1. waterdog could you direct me to a post where someone was able to run pl9 at 500fsb 1/1 divider on the MAXII? cause ive searched and cant find it.

Helloo,

Finally weekend .

Can you guys report what kind of temps are you gettin on Power (load)?

In p95 in stress I am hitting 49 on 4ghz with no case so probably around 52 - 55 in closed case.

After 4 reseating of Cooling on mobo I got finally nice NB and SB temps (SB 38C 1.01v and NB 45C 1.31v - no case but also one fan only on CPU).

I tried 2 different types of washers and mixture of them.

Best results I got with same washers for all screws in my case 2mm silicon are doing much better job then 1mm steel.

Putting washers only for NB is not a good idea from my observations and worth mentioning my new MF2 had overheating issue on idle on both MB and SB - they were hitting 54 after few minutes in BIOS.

At least my cpu needs 1.25v Vtt and doesn't looses stability up to 1.41v so i have a wider selection of vNB. Still this bug is unacceptable and ruins the whole picture...

As for the pcie bug, do u know if P5Q Del is affected also?

Hmmm, interesting. Have u run any comparing benchs?

He was refering to the multi not PL level....

Anyway I'm about to sell all of my Asus hardware if they dont smarten up with RMA.

How do you like the Giga board?
can you be so kind as to post a few benches here, if I get piss'd at Asus tonight I'm selling everything and buying new from another manufacturer in the morning.
I was very interested in the UD3P but didnt bother cause of i7

seban

My power is showing at 45c in Probe software.....overclock as below:

[seban]

Thx Bito.

Nice CPU you got there BTW. Really nice vcore.

Those temp are in case? Is it WC setup? If not which cooler do you use?

[radaja]

grnfinger your right.two diferent pages.i love this board,bieng new to overclocking,i dont have much to base it on.ive only owned three motherboards.my first for about two weeks(p5q-d)liked it,but wanted more.second( maxII havent had a good one)hopefully that will change when i get my replacement.third one(UD3P)and maybe i got a good one but everyday my results get better.which makes it real fun. but anyway here are some test.@joebar i couldnt cause my maxII wouldnt allow me to go above 495fsb.

[Grnfinger]

jeebus that looks impressive.

Thanks for the screenies

[JoeBar]

Thanks for the benchs radaja. Nice scores!


Could u pls run a 1:1 bench?

[radaja]

grnfingerand joebar thanks. heres a 1:1 bench.

[JoeBar]

Thanks for the bench m8!

Very nice scores! What pl do u have?

[radaja]

here you go

[GeorgeVasil]

As for the pcie bug, do u know if P5Q Del is affected also?

2 P5Q-Deluxe i tryied had the same problem.

[CryptiK]

Yes same here, my P5Q-Deluxe also had that that issue. The P5Q series exhibits very strange unpredictable behaviour when pushed, I think they are a workstation board at best, you can't really do anything with them. The best P45 from Asus is this M2F, however the bios features and their bios coding for it leaves a lot to be desired, the DFI and Gigabyte P45 boards are way better for Duals, and the UD3P and EP45-Extreme also handle quads very well, and companies other than Asus really seem to be putting a lot of effort into their bioses providing way more options & tweaks, and they all work as they should. I'd like to see Asus lift their game in regard to BIOSes.

I think I will be selling my board and getting either a UD3P, or a DFI X48 board.

[Rocks]

What would you guys say are the safest highest voltages for a 4 ghz OC on the Q9550 for this board.

Max CPU v =?
MaxCPU VTT =?
Max CPU PLL v =?
Max NB v= ?

Thanks

[CryptiK]

Max CPU v = ~1.40v
MaxCPU VTT = ~1.30v
Max CPU PLL v = ~1.57v
Max NB v= 1.4 - 1.5v depending on load temps

**********************************

I have been trying to get this board to do 541 FSB / 650 MHz and it does not want to do it. I think I'd have to use around 1.60 vNB on PL10 and I doubt the cooling could handle it.

[Rocks]

Thanks man, now listen to this. I was using the KET 1307 when you were helping me tweak my . Got everything stable and said well lets see what 1702 is like...big mistake. Couldnt even come close to stability. I also went back to the regular 1307. Prime 95 would error out with 10 seconds everytime. I put the KET 1307 back on and stable again. Go figure man. WTF is going on here?

I can't get 500 FSB to boot into windows for the life of me. I have tried everything. It just won't do it for me.

I think it is impossible for me to get 4ghz stable with such a low CPU VTT. Ill give it a shot a let you know the results...

--Rocks

[The Water Dog]

So KET 1307 is the best bios to oc?
Maybe i should try that one
