ASUS Maximus II Formula - new P45 king?

[Grnfinger]

Could u pls give us any more info?

I tried for starts running CPU and NB Clock Skew on normal, and needed to set vCore at 1.38 for 4.2GHz, so new chip and all I started tweaking ( 500 FSB still evades me ) I set CPU and NB skews to 100ps and lowerd vcore, it passed. set it to 200ps and lowerd, it passed again. 300ps and lowerd it failed, up'd vCore to 1.325 @ 300ps on both skews it passes linpak and prime.

Now on to NB volts, started with NB GTL set to auto, set ram at 1121MHz with vNB set to 1.39

DRAM Static Read Control: Enabled
Dram Read Training : Enabled
MEM OC Charger : Disabled
Ai Clock Twister : Stronger
Transaction Booster : Manual

Common Performance Level [8]

CPU would pass but once I brought the memory in to play it would fail.
So I upped NB volts to 1.45775 and it would pass anything I tossed at it.
Set NB GTL's to +30 and I could lower vNB to 1.41, anything lower and it fails.
If I run 1:1 PL10 I can drop vNB to 1.30 and pass all day long. I like the improved bandwidth 1121 offers and I'm on water so the extra volts are not an issue.

Will test further this weekend, this time of year my job has me pretty busy so has not been alot of "free" time for me.

Thanks for the advice, will try that this weekend.

Latency is crapola but teh bandwidth is rather decent.

[JoeBar]

Thanks for sharing your findings Grnfinger!

BTW, why do u have mem oc charger set to enabled? Try with it disabled and check your mem scores.

It is actually disabled its a typo from another template I posted.
I will edit the post.

Why wouldn't you have mem oc charger enabled?

[Grnfinger]

Why wouldn't you have mem oc charger enabled?

Because it limits bandwidth

sorry, so the last and better mod bios is the 1901.201 ?

Well, managed to get into windows a 480fsb & @ 46min into prime blend...

[Nevin]

I want to ask is there someone with 8x560 or 8x570 stable, I need to see some settings.

I have a huge problem with this board... When I use 1,7vcore it fine but anything above that will make the system failing. It dies when I get the "overvoltage protection bla bla bla" I can get into bios and there when I monitor the voltage it's 1,9xv (when setting 1,74v). I'm using kets modded bios. Would a new bios help me?

A new bios is definately worth a try, I have 1802 on bios1 and 1901 on bios2
Works great, benching setup for 1 and 24/7 setup for the other.

Try the latest BIOS, and try disabling Loadline Calibration if you have it enabled.

Hi guys, could you tell me some tips&triks to get my 9550 work @ 500 fsb ?

mi result up to now

Any idea to make it stable @Strong or Stronger?

Also,when you flash to 1901 BIOS,RAID ICHx status disappears ?

[CryptiK]

You will need more vNB to get 470 FSB PL8 stable with strong/stronger.

I run 470 x 9 PL8 moderate 24/7 and it takes ~1.34vNB for total stability - HCI memtest really loads up the NB and at 1.30 - 1.32v I get errors before 1000% coverage.

I spent 4 weeks trying to get 490 stable. I can bench at 500, but there is no 24/7 stability. I gave up, and am running it at 471 now. I know I can go higher, but pushing the FSB to the ragged edge doesn't work well on this board. It's flaky and settings that were stable yesterday may not be stable today.

It looks like you're running small-fft. That's good for CPU top speed, but for testing the limits of the FSB I suggest you try large-fft. I think you'll see it fail much sooner and at lower FSB speeds.

[Rocks]

I'm done with this board and it's crappy memory bandwidth/bugs and support. Just bought a Rampage Extreme. In case you are interested they have them here for dirt cheap:

Hope you guys get a good working BIOS. I will be selling my board on ebay within the next few weeks.

So I really haven't done too long of stability testing through p95 but I am at 480fsb
1.43v
2.10dram
1.10sb
1.55sb15
1.69pll
1.55nb
1.40vtt

did some np & cpu delay of 100ps and channel A & B 100ps delay; and a few other tweaks but before I get going on my UD3R board. I am wondering if 110f is too hot for my NB - I have active cooling by a 120x38mm fan blowing over the area but it still gets warmer.

[Grnfinger]

110F = 43C
Thats not bad mine hits that after a few hours of benching and stability is there
Intel white paper states it can take alot more, I have found if you keep it under 50c or 122f your good

[529th]

Cool, thanks

I have also have another question: what is the Ai Clock Twister? And does the UD3R have something comparable to this? Thanks

i'll try large fft

yes it's quite hard to get 500.. probably with nexts bios we could get al least 494x8.5 for 24/7

I wouldn't count on it

I'm no engineer so here is my best attempt to explain it.

Ai Clock Twister will tighten your sub timings increasing performance/bandwidth when set to strong or stronger
Moderate will run sub timing at or around stock
Light will relax them a tad allowing for improved overclocking.

Not sure what Gigabyte calls it or if they have it as an option in the bios.
