hello fellow friends, i`m in need of some help. i can get a stable overclock at 3.0GHz with my q6600, the only thing i did was put the cpu voltage from 2.750v to 3.12v and raise the FSB to 1334 (333.7MHz) and set the memory to 667MHz. i let everything else on AUTO.

my problem is i can`t get anything pass 3.0GHz :( i wanna know from you guys what settings should i put to run stable at 3.4 or 3.6GHz ( i would like to try and reach 3.6Ghz :) ).

my setup is this:

Motherboard - Asus P5N32E-SLI PLUS
Cpu - Intel Core 2 Quad Q6600 | VID 2.750v | Stepping - B | Revision - G0 |
Memory - 2 x 1GB Corsair XMS2 DDR 2 800MHz
CPU Cooler - Zalman ultra Silent
HDD - 2 x 500GB Seagate Barracuda SATA 7200.11

The final idea is , i want to know what settings should i put in my bios to have a stable OC (voltages , memory timmings, etc), my cpu is cool reaching 40-45 degrees IDLE and 55-62 at Full load using Prime 95

any help is really trully appreciated :)

yes there is ... i can post a pic from core temp the VID is 1.2750v and im curently using 1.328v

but besides that ... what should i do to have a stable OC ??

 


There's a huge difference between 1.328 volts and your earlier claim of 2.750 to 3.12 volts. That kind of voltage would likely fry your CPU immediately.

Generally, you'll need to bump up your CPU voltage a little bit at a time until you get it stable.

On my crap 680i LT SLI motherboard, I have to set my BIOS @ 1.4v in order for vDroop to hit 1.35v to run a stable 3.2Ghz. I've got a higher VID chip than you do, so theoretically you should be able to OC at lower voltage than me. Again, theoretically. Also depends on mobo chipset, etc etc

If you're changing voltage settings on something in your BIOS which actually lets you adjust from 2.75 to 3.12V I'd stop doing such. You could seriously damage something.

Your CPU will normally be somewhere from 1.2v to 1.6v (which is HIGH) on most motherboards. Memory is usually 1.8v to 2.1v depending on actual memory chips. I wouldn't screw with much else unless you really, really know what you're doing.

uppps.. lol.. yeah.. sorry for the voltages.. i miss typed :p..

but do i need to change any voltages from NB , SB or Memory?

and what about the timmings??

im sooo exited cuz i got the new aftermarket cooler to start overclocking that i didn't even saw that i miss typed lol...
 


Personally I didn't make any changes to my NB, SB, or Memory. I actually unlinked my memory and left it at the standard 800Mhz. All I changed was my CPU voltage, everything else was on AUTO. Except my memory is EPP so I used the custom settings supplied by Corsair.

Careful as you change voltage for NB, SB and such, you could smoke something if you start playing with stuff.

nahh.. :( i put 1.4v with 9*333 and nothing .. the board restarts and shows the ASUS LOGO and just hangs there i can't even press delete to enter the bios so i restarted the pc and the board automatically reset.

i also tryed 8x400 and i got pass the asus logo, the windows logon screen also.. but after the windows logon screen my monitor just went black :(

what can i do :(:(:( ????

OP - I used to have the same motherboard and could never get my Q6600 stable past 3.0Ghz. My opinion is that the motherboard is terrible for overclocking quads on, as I have managed 4.1Ghz (watercooled) on my Maximus Formula. I tried every voltage trick and bios tweak, yet it would never be prime or superpi stable above 3.0Ghz.

Hey I don't think you need 1.4V to reach above 3.3ghz.
mine is running on 1.368 @3.3 and it's Prime 95 stable
I think there's something wrong with your MB.
I set the NB,SB to normal but I raised my DDR to 2.2 their running @1101 MHZ

MB: GIGABYTE P35 DS3R FBS (1333,oc1600) DDRII(1066,oc1200)
VGA: ATI 4870 512 MB
CPU: Q6600 @3.3 Stepping B
Cooled with ASUS Tritton 79
RAM: 4X 1GB A DATA 1066+
HDD: 500 GB WD 7200RPM

Did you try 7x400? That gives you only 2800, but if that fails you know the mobo isn't good for that high of an FSB.

Anyone else find it odd that he got that far with 8x400, but failed once windows booted? I wonder if his PSU isn't strong enough for is setup. (once windows loads and his GPU starts sucking 12V juice.)

do you think it's a PSU problem??? im gunna try 7 x 400 and see what happens...
ill post the results here in a few min :)

I thought you couldn't run an 8 pin board with only 4 pins?

If you can't run 7x400 (2.8GHz) I'm inclined to believe the others when they say its the motherboard. At this point you have nothing to lose if you want to try flashing the bios, but I doubt it will help. Running proper power to the board might help, but I'm not 100% sure.

There are no P45 chipset motherboards in Mozambique? Try to find a P35 board, not a lot of difference. (other then no PCIe 2 slots...)
