OK, just got my new install up and running and after a quick tinker I have the following -

Q6600 go with 1.250 VID
Asus P5k-e Mobo
2 x 1Gb OCZ Platinum Rev 2 RAM.

CPU cooled with a D Tec Fuzion Rev 1 with quad nozzle, Laing DDC ultra pump and PA120.3 rad.

I have it running at 3.6Ghz 15 hours prime stable with v core set at 1.4v in the bios. I have done the pencil mod which has allowed me to bring the v core down from 1.425v in the bios and zero vdroop now.

What am I after, well, ive been trawling through all the threads I can find to see if I can understand what all the bios entries are but am probably more confused now than when I started. This is my first go with an Intel as ive always been AMD.
Ive had a go at 3.7Ghz using 9 x 411Mhz but had to up the v core 3 notches but still couldnt get past 35 mins of OCCT so could someone please enlighten me as to where to start.
My bios settings are multi and FSB set manually. first 4 ram settings set manually, v core and ram voltage set manually, northbridge at 1.55v from what I can remember and the spread spectrums disabled. Everything else is set to auto.

All help appreciated.
 
I have 4.023 :) see my sig for link to guide (Here: link)

some things you might want to try from top of my head:

* Not sure what your RAM is set at but make sure it has some really lose timmings and disable trasnaction booster
* BIOS version 0602, I cant get any higher than 3.8ish on the newer ones
* Disable everything that you dont need on the motherboard wifi etc...
* I always found at higher FSB that enabling speedstep gave better stability (no idea why)
* Past 4.1ghz defo need to start playing with ref voltages

all I can think of right now, if I can find my notes i'll post some more up in a bit, done a re-install recently but bound to be saved somewhere

Hey snap, apart from the ram i've got the same setup,
that i've just bought,
after along service with AMD
......

stressin mine now.... 2565 mhz
1.2375
multiplier 9
bus spees 285
dram 342
fsb:dram 5:6

just running her in for a few hours then gonna try for 2.8 my self....

I have the same system but running @ 3.2Ghz.
Can you post your settings?

just followed your guide on your sig.... forgot to set the multipler to 8 :D so now i'm running 3600.......

follow this guys guide and u'll be clocking socks off it

I to was very confussed by the BIOS on this board.... but thats coming from AMD for the past 5 years..
 
Ok These Are Mine For 3.2

FSB Strap To North Bridge: 333mhz
FSB Frequency: 400
CPU Multi: 8
PCIE: 101
RAM: Set As Per Manufacture
Transaction Booster: Depends on your RAM 1 is probably a good start, wack it up to more and run some blend test for stability testing
CPU Voltage: 1.22 (This Will Depend On your Q6600)
CPU Ref: Auto (Shouldnt Need Em)
CPU Voltage Dampner: Enabled
CPU PLL: Auto
FSB Termination: 1.3
Northbridge Voltage: 1.4

VP - This is all the settings I have altered in jumper free configuration. If its not listed then ive left it on automatic.

AI overclock - Manual
CPU ratio setting - 9
FSB Frequency - 400
PCIE Frequency - 101
DRAM Freq - DDR2 801Mhz
DRAM Command - 2N
DRAM Timing - Manual
CAS Latency - 5
RAS - CAS - 5
RAS Pre time - 5
RAS Act - 15
CPU Volt 1.4000v
NB Voltage - 1.4v
SB Voltage 1.05v
Load line Calibration - Enabled
CPU Spread spectrum - Disabled
PCIE Spread spectrum - Disabled

Thats it.

That is what I will probably run 24/7 but I will tighten the timings if I dont go any further but am unsure as it would seem the VID is good at 1.250 so would like to try for 3.8Ghz or more hence the reason for the thread.

Ive turned everything off I dont want in the Bios and speedstep is enabled.
I flashed the board to the latest BIOS, cant remember which but its the latest on ASUS website. Transaction booster is on auto I think so I will turn that off and have a go later to see what I can do.

What is the accepted norm for volts to reach say 3.8Ghz as I dont want to over cook it?
 
Of course you could know every BIOS setting inside out and tweak everything just so but at the end of the day you will need a good chip to get an uber overclock.

It's never easy the first time round knowing if you goofed your overclock settings or indeed your chip/mobo/memory has maxed!

The P5K-E is the business though! :)
 
The chip can bench at around 4.2ghz, I ran @ that clock speed 24/7 for a couple of months but tbh you dont need 4ghz to browse the web :) so atm I am at 3.6ghz
 
After some tinkering and trial and error I have now managed 3.72Ghz 1 hour OCCT stable stressing the CPU. Had to up the vcore in bios 3 notches to 1.4375 from 1.400v.

In my experience, if it can pass an hour of OCCT it wil do more than 8 hours prime, but I always test just to be sure.

My idle temps have increased by about 2 degrees across all cores and highest recorded with OCCT was about 58c, an indication of Prime temps aswell.

Whats the max recommended volts for 24/7 on a GO Q6600?

Way more than the 1.4v you are putting through now!

If you only need 1.4v for 3.6Ghz then that is good. I needed 1.4v to hit 3.4Ghz with my VID 1.25 quad.

I have seen people running 1.6v+ volts to get 3.8Ghz and over and in general, unless they have very,very good water or air cooling, that is only used for benchmarks and not 24/7

Just keep upping the FSB slowly and the cpu volt everytime it falls over.

You might have a very good chip which only needs 1.5v to get to 3.8Ghz but each chip is different.

Oh and the 1.55v in my sig is windows reading not bios. From memory mine is set above 1.6v but drops in windows to 1.55v
 
Had it running prime over night. 11 hours stable at 3.72Ghz with vcore in bios set at 1.4375 and in windows shows 1.416v but drops to 1.408v under load.

Temps reached between 48 and 56c. I presume the temp difference occurs depending on wether its stressing CPU or RAM.

Will try for 3.8Ghz tonight and see how many more notches up the vcore requires.

Greebo , is that you 24/7 speed or have you dropped it for daily use?
