Vero ... unica pecca non riuscire a tenere i pl bassi e la banda passante.

Con le Rampage tenevo pl6 e avevo bande passanti e meno ns nelle risposte... provato con Everest, ovviamente a parità di settaggi e di hw esclusa la mobo.

Vero pure quello che dici tu

Mafio tu che ci leggi, con la giga che pl tieni? E con la biostar cosa tenevi?

I found a way to do 500FSB 24/7 stable on a quad on this board, I would like to share how I did it, and it may help everybody to reach higher FSB's too, if not 500 for quad.
I don't have a dualcore, so I am writing based on my quad experience.
I also believe, this method is the right way to fine tune your Maximus II Formula. Even if you are not going for 500FSB 24/7 on a quad, if you do the guide, you will find that you will be able to drop a lot of your volts. Just randonly setting values like GTL's, SKEWS, etc, are not the best way to find the sweet spot of your mother board.
At the end of this guide you will have no "auto" settings left on your bios. Everything is covered, and fine tunned.



Guide for full tunning the Maximus II Formula for high FSB / MEM / CLOCK for 24/7 use

How to start?
BIOS 1901
With your bios reseted (everything on auto), enter reasonable 24/7 volts for high FSB / mem clock like the ones below:

1.xxv CPU (you know what they are)
1.30v FSB
1.55v PLL
2.00v DIMM (Respect your ram spec)
1.45v NB (This one should be 1.45v)
1.15v SB1.1 (This one you might leave at the lowest)
1.55v SB1.5 (This one you might leave at the lowest)

Now, find the highest FSB that will boot and enter windows, and run prime blend for some minutes at least.
Keep on 333 strap if possible, and set your ram to the highest possible, adjusting the Vdimm.
Enter the 1st, 2nd and 3th ram information manually, copying all the values that "auto" settings show, replacing only the Row Refresh Recycle Time to 55 DRAM Clocks.
LEAVE IT ON PL10 - MODERATE for now.
Set your multiplier to the one that will result in the closest final CPU clock you aim for 24/7 use.
Remember, this set (fsb, multiplier and ram) must be unstable, but able to run prime for about some minutes at least.

Now the fine tune begins.

PS: The guide is cumulative, so you should keep settings before starting to test others. The guide is already on the order you should fine tune the settings.



1) CPU GTL Reference 0, 1, 2 and 3

You don't need to do any calculations.
There are only 7 possible CPU GTL's combinations that makes sense from 1.20vFSB to 1.44vFSB.
If you are under 1.20vFSB, then you don't need this guide, since you are performing a "junior" overclock.
Anything higher then 1.40vFSB is a NO for 45nm and higher then 1.44vFSB is NO for 65nm. So there is no way you will be out of this range from 1.20vFSB - 1.44vFSB.
The only seven values that are "right" are listed below.
If you are using any CPU GTL value different then this, then, from my calculations and experience, you are doing it wrong, and don't have the optimal values for your setttings, and that is slowing your overclock potencial down.

From 1.20VTT to 1.32VTT
CPU GTL Reference (0): +30mV | +20mV | +10mV
CPU GTL Reference (1): -10mV | -20mV | -30mV
CPU GTL Reference (2): +30mV | +20mV | +10mV
CPU GTL Reference (3): -10mV | -20mV | -30mV

From 1.32VTT to 1.44VTT
CPU GTL Reference (0): +40mV | +30mV | +20mV | +10mV
CPU GTL Reference (1): -05mV | -15mV | -25mv | -35mV
CPU GTL Reference (2): +40mV | +30mV | +20mV | +10mV
CPU GTL Reference (3): -05mV | -15mV | -25mv | -35mV

You should test all the possible CPU GTL's listed above, and keep of course, the most stable one.
To do this, you should try at least 2 or 3 different unstable sets of high FSB's and CPU clocks (including the one you are at now), that are about 5-10mim prime stable only.
By testing all of them, and writing the results down (how long it last before crashing on prime), you will see a patter.
That is why you need to do it with 2 or 3 sets of unstable settings, so you can really understand the patter of the results, and pic the most stable CPU GTL.
Now, you want some sets that are 5mim prime stable only, so you don't need to wait a lot before each test. Also, you need to test sets that are close to your goal FSB / CPU clock.
That is it, now you have your perfect CPU GTL.



2) NB GTL Reference

At this time, you must have your CPU GTL's defined. Keep them.
NB GTL Reference might vary from -80mV to +80mV of even more. The best way to find the optimal one, is testing them all and finding the most stable one.
For this test, you should keep the high FSB (always), and use high DDR2 clock, with PL8 and a STRONG or STRONGER clock twister. Any thing that can put some stress on the NB.
You should prime blend again, at least 2 or 3 sets of unstable settings, and write the results down, as you change your NB GTL.
You will see a patter, and you should keep the most stable one.



3) DDR2 CHA / DDR2 CHB and NB DDR2 Reference Voltages

FOR DDR2 CHA / CHB YOU SHOULD NOT GOT BEYOND -25mV - +25mV
FOR NB DDR2 REFERENCE YOU SHOULD NOT GOT BEYOND -50mV - +50mV

So there are a few values only to be tested.
Do the same test you did on Item2, and now, with these settings, you should improve them.
Let's say you got +20mV as your NB GTL on Item2, because it was the most stable one, and it could make a 10mim in prime before crashing.
Now, you repeat that same test, but with different combinations of DDR2 CHA / DDR2 CHB and NB DDR2 Reference voltages, respecting the limits.
You will keep, of course, the best combination, and if without these settings you were getting 10 mim before crashing, now with the right combination, you will improve the time.

Start testing:
+12.5
+12.5
+25

Then:
+12.5
+12.5
-25

and keep going...



4) CPU / NB SKEWS

At this point, you should have all settings from item 1, 2 and 3 done. This is a cumulative guide, so you should keep every setting before starting to test a new one.
Ok, this is VERY easy to find. SKEWS are very sensitive, so the results will appear right away, either good or bad.
YOU NEED TO TEST THESE AS A PAIR.
From my experience, I can say that only delayed skews are good, but maybe that is not true for your system. So you should try advanced too.
Start with:

CPU SKEW - NB SKEW
normal - delay 100
delay 100 - normal
delay 100 - delay 100
delay 100 - delay 200
delay 200 - delay 100

and so on...
Since this is very sensitive, when you start to prime, some of the settings will crash right away. Others will last only a few seconds...
Only the few good combinations will last long. And it will be very easy to define the most stable one. Keep it.



5) DRAM SKEWS

This are not as much sensitive as the CPU and NB skews, but they are also easy to set.
Just repeat the Item4 test, and try to lower your PL, or raise your mem frequency, or add something that will put more stress to the ram, like a clock twister or something.
For me, only delayed values were good, but you might try advanced too.
Keep changing them, and writing the results down, and you will be able to tell the most stable set.



6) DRAM Static Read Control

Leave it disabled



7) DRAM Read Training

Leave it disabled



8) MEM OC CHARGER

Leave it enabled



9) MEM Timings (1st, 2nd and 3th information)

If you want, this is the time to fine tune it. If you have 2x1GB you can set you Row Refresh Recycle Time to 40 DRAM Clocks. Set it to 50 for 2x2GB, and so one.



10) PULLINS

Keep them disabled, they don't work on bios 1901.



11) CPU Configuration

Disable everything there.



12) Load line calibration

Enabled



13) CPU and PCI-E Spread Spectrum

Disabled



Ok, at this point, you have fine tunned your motherboard. No auto settings anymore.
But it is not stable yet, far from it.
Now, you will find and understand how the voltages affect your overclock.

vCPU - Helps most raw cpu speed
vFSB - Helps at high FSB
vPLL - Helps at high FSB
vDIMM - Helps high ram clocks.
vNB - Helps high fsb and high ram clock
vSB1.1 - Helps with raid or several HDDs / optical
vSB1.5 - Helps at PCI-E frequency (when higher then 100)

Now its up to you, to find the correct volts, to keep the system stable at a high FSB and MEM clock.

You will now, only mess with the following:

- FSB / RAM clock
- Performance Level
- AI Clock Twisters
- And all the voltages (vCPU, VTT, etc)

No need to change GTLs, SKEWS, etc...

That is it.

Con le Rampage tenevo pl6 e avevo bande passanti e meno ns nelle risposte... provato con Everest, ovviamente a parità di settaggi e di hw esclusa la mobo.

puoi postare qualche screen? io ne ho molti su trd e banda passante, così li confrontiamo

@kurtz: sarebbe interessante capire perchè i miei settaggi sono così diversi da quelli di xs qualcuno è salito di bus oltre 600mhz fsb, per fare qualche confronto?

guarda Sims ha aggiornato or ora ... nn lo so Damiano ... probabilmente si tratta di una diversa strategia ... la tua orientata al max possibile la loro alla solidità ...

riposta qua i tuoi che eventualmente glieli linko e sentiamo che dicono ... o scrivi direttamente a loro così sentiamo che dicono ...

[beleno]

più che altro la mia orientata alla cpu, la loro alla mobo, una diversa prospettiva
linkami pure tu visto che sei ben avviato sul loro thread

ehm dove trovo i tuoi results? cmq si concordo, tu sei orientato sulla cpu .. anche se io per esempio con i tuoi gtls nn mi ci ritrovavo ... d'altronde lo avevo anche letto dove dicevano che la MILF gradisce GTL alti ...

sto per ordinare questa mobo che a sentire è fantastica!!! mi consigliate 2X2 gb ddr2 da stare sui 100 euro per overclock??

dipende che oc ci vuoi fare comunque come dice k vanno quasi tutte bene visto che non montano chip micron i banchi da 2 gb comunque dai uno sguardo alle g.skill
