ASUS Maximus II Formula - new P45 king?

[kup]

hell im happy with 2-3 hrs prime blend.thats quite the accomplishment with a quad and the MIIF

I woke up this morning to a locked screen after about 7 hours (according to start time and frozen clock) so have started again for you. My only screenie was just under 2hours in so I'll post that plus any more I have this evening.

Seems like you're doing extrordinarily well Kup. Like others have said, it's not that we don't trust you, but so you can confirm the virtually unbeleivable! The amount of time I've wasted trying to get my board stable at 460+fsb with my old quad, and ~500fsb stable with my current chip is silly, and I'm just speaking for myself! Massive kudos for getting as far as you have, would be great to see higher clocks. Does it still behave if you up the multi?

[kup]

Cheers dude. Sorry for coming in here all headstrong, I didn't realise it was such a high fsb until you guys said. 500 was a breeze and the 510 and 520 were a bit of a struggle which is why I thought lots of people would have done it too.

I usually test with a quick 3run blast on LinX and if it passes that I'll try for at least 6hours Prime x64 Blend or Small for cpu.

Funny enough, with only 4GB installed I experience more instability than with 8GB...lol.

Will be able to try that for myself shortly. Turns out my RMA'd sticks have been sitting in our local sorting office for a week and I've had no 'failed delivery' card... Royal mail are doing themselves no favours at the moment!

What revision is your board? 1.03G?

[kup]

Not sure off the top of my head but I'll have a look when I get home tonight.

[kup]

As promised...



This crashed after five hours but this is during the day so it's warmer. I came home to find my curtain had fallen down (lol) and was caught in the fan on my heatsink...oops!

It behaves @ 500MHz up to 3.5GHz and then I can't go any further because I go past my CPU's limit (bloody thing is 3.825GHz stable with only 1.45v but hits a solid wall right there as documented above ^^^).

[radaja]

those are insanley high volts on the vtt/NB/pll
but nice job

I don't run it like that for 24/7 operation. I'll work on lowering those volts.

Any ideas why I would hit a wall with overclocking, as I commented on above?

[radaja]

not really sure why,but maybe just try getting 7x500@3500 stable with decent voltages.
does 7.5x500@3750 work?

Q6600 here so no half multipliers.

I've flashed Ket's mBios 1901v2 and will retest everything again. I'm sure I had it running past my 'wall' on the 1901 bios before I flashed it but I don't have anything documented in my notebook.

EDIT: And this board is a rev 1.02g.

[radaja]

whats the chipset rev?you can find it in cpuz under the motherboard tab,its either A2 or A3
oh i didnt know that about the Q6600.just stick to 7 then

[kup]

It's an A3 chipset.

[In-Fluence]

They are very high volts. I bet you would be able to get that 520MHz setting stable and lower a load of volts after tuning your NB and CPU GTLs. Very impressive indeed though, well done... I've not tried such high NB volts myself but with it sitting naked against a waterblock and it not hitting more than 40°C with over 1.5v, I'm starting to wonder if a bigger bump would make all the difference...

[kup]

Ok, I'm struggling with the GTL values. What should they add up to? CPU GTL equation should add up to...? And NB GTL equation should up to? I've used the settings presented in the GTL thread for 65nm CPUs (+50,+10,+50,+10) and it lowered both 3.6GHz and 3.8GHz required vCore for LinX x64 stability (3.6GHz @ 1.35v and 3.8GHz @ 1.4375v) but I'm unsure what the NB GTL should add up to, is it supposed to be whatever the vNB is?

[humeyboy]

I too have not got a real answer on NB GTL's but I cannot run Minus only Auto or Positive.

I am at 475FSB on 1.27v NB & VTT and NB seems best at +40.

I can get 485FSB stable with Ket's Bios but the gain in voltage although not too high is not worth 10MHZ IMO.

I want next 500FSB or I simply will stay at 475FSB.

Today I wasted all my time on once again trying to clock this POS to stable 490+FSB and no matter how much voltage or what tweaks its no go for long if it even boots (ain't the same any 2 boots).

If I were you I would be thankful and clock down to 5000FSB and lower voltages (yours are crazy high).

The voltages are nice and low again now, that was only a bench/test run.

I've found a nice guide on GTL settings here - http://www.overclock.net/intel-mothe...ml#post7161320

I'm a bit confused as to which I tweak to what for a 65nm CPU, do I tweak .667 to .635 or .635 to .667 for the CPU GTL?

[humeyboy]

Just found out what I set was correct for my NB.

Treat it the same as the CPU GTL's (weird as the NB is not the same nm as the CPU I have).

[Marcio]

kup, those are ridiculous high volts on pll / vtt / nb.
You are for sure degrading some components. I wouldn't run prime for hours with those volts.

Anyway, look at simps's guide on this thread, he had a 65nm quad too, and he got it 24/7 500FSB stable with reasonable volts.

[kup]

The volts are much lower now. That was just for 520MHz.

[In-Fluence]

I couldn't agree more with Marcio It seems like you're one of the lucky ones who got a good CPU & board combo and it could be that yours will behave the same as Simp's setup did. It's a very thorough guide, worth trying in your case I think

Anyone got a link to his post? I can't use the search feature at work.

Cheers Influence. I've just had a try but my 500MHz voltages are already lower. I'll keep trying for more.

This Q6600 is pissing me off now, it literally stops dead @ somewhere between 3.7GHz and 3.9GHz with any voltage over 1.464v...no crashes, no lockups, just power down.

I have once again Google'd some keywords and found a few sites concerning this Mobo and OC'ing.

You have to take some of the info as BS and other info as a "trial and error thing", but there is also good info out there.

Now what I did not tell you the other day was that although its true I was doing some PC work the real reason I'm on 4GB for now is due to me dropping 1 of my Modules onto a hard floor and now it will not even post.

I have found 2 settings (I have messed with them before but there is too many variables) and now I am 100% stable @ 490FSB, 99% stable @ 495FSB (still tweaking/testing).

When I get 495FSB 100% stable and I try lower some voltages and tweak GTL's more and do a proper long Prime/Orthos and then I will then use these settings to try and get 500FSB stable as I will only need to raise a few of many settings I hope.

I do not see my 8GB being an issue as this Mobo was made for 16GB and I have had the exact same stable or failed settings with 1-4 Modules (2GB-8GB).

[kup]

What were the two settings you found to provide more stability?
