Vantage P15071 in Vista x64
Hi,
I have the system in my signature, and without detailing it, my P965 won't give me 1MHz above 390 FSB, even after NB strap change at 401MHz and above, whatever voltage settings/timings/number of ram modules... I try.
It is, exactly the same limit with my previous Q6600 B3.
I looked on the main topics of P35 and X38 boards, and it seems the Maximus is the way to go.
The >1.5vcore bug with quads is bizarre though. As it presents, it could be a hardware issue. I won't like to spend so much money and sit at 3.6GHz because I can't shoot my G0 with some elctric shocks![]()
So I have some questions if you can help me:
1- I'd like to be sure of that >1.5 vcore issue with quad cores. Does-it mean, no OC above 1.5v?
2- Also, any one tried the graphite mods if they fixed this issue instead of maybe a buggy PLL bios setting?
3- When OC the Q6600 above 3.8/3.9GHz, so very high FSB for a quad, what temperatures are going the NB and SB while using Prime95 Large FFT, or better, OCCT last beta in RAM mode with the stock cooling (passive)
4- I have two HR-09U and one HR-05 IFX for cooling the mosfets and NB. I could add a HR-05 IFX for the SB. Is all the heatsinks soldered with the heatpipes or they can be unmounted separately. As the X38 is known to be hotter than a P35, is the passive cooling on the MB or even a NB watercooling enough to cool the mosfets and NB on a highly overclocked quad? (I mean above 1.5 vcore and 3.6GHz)
Many thanks for all owners of the Maximus giving feedback for future users

Sooo okay. I have something that may help everyone but I don't know if this is old news.
But firstmy RAM failed the tests again with all 4 sticks. I'm just gonna leave it as it is. I should've gotten the G Skill that Gar has
I upped the voltage to 2.3 and there is only 1 failure so far.
Now to the important stuff....
Has anyone heard of the EPU pencil mod for this board?
I was at a comp store today and met the owner who has this board at 4.005 Ghz!
I forget the FSB I saw but it was on a x9 multiplier with vCore at 1.51v and 0602 BIOS.
The temps were VERY cool too. Everything was below 40 deg in ASUS probe (CPU was around low 30s) and under load.
He said he was cooling on air and all this was thanks to a pencil mod for the EPU since the EPU was causing all the overclocking problems with this board.
There is a resistor on the top right of the EPU that he uses a 4B pencil to short the two ends of.
The other thing is that he was using some new RAM that is not available (in Canada) yet. The timings and latency was amazing. Sorry I didn't get more but I haven't slept all night![]()
If I get a chance later, I will try to post a pic of the resistor to pencil out.
OR maybe someone else can post a pic of the EPU and surrounding resistors and I will edit and repost.
OR is all that I am saying just old news???
I didn't see a difference between 0602 & 0701 as far as Everset is concerned:

Question : Why do some overclockers switch into d*ckmode when money is involved
Remark : They call me Pro AsusSaaya yupp, I agree
