***The Official Core i7 Overclocking Thread***

hi all this is my baby temps are 40 idle and 70 after linx 20 passes , for 24/7 i am using oc.3.5 only 1.15v after p6t new bios 0904 everything just flies

You may easy, watercooling will certainly help, CO's tend to need 1.4v ono for 4ghz, DO's on the other hand seem to top out at 1.3v ono (1.2750 here on p6t dlx v2). On my setup, 3.6 ghz came with 1.18v, only had to jump to 1.2500 for 3.8ghz, (21x multi), then 1.2750 for 4.0 ghz (21x193), 4050 mhz, ram at 1.64v, 7-7-7-24 1T. 1547mhz. The great thing with the p6t boards is the bios, previously i ran an s775 p5q deluxe with a q9550, bios layout is almost identical. Definitely a very friendly bios to overclock on. I look forward to seeing how you get on.:)

Thanks setter,

Well I can hope, 4GHZ would be nice but 3.6 is fine by me.

I'll have a play and see what I can get 24/7:cool:
 
As I am complete noob when it comes to overclocking, I'd really appreciate an up-to-date guide to i7 oveclocking please :)

My system:
CPU - Intel Core i7 860 @ 2.80
GPU - XFX HD5850 XXX Edition - GPU clock 775Mhz, Memory clock 1125Mhz
RAM - OCZ Platinum 1333Mhz 8GB ((2 x 2GB) x 2)
PSU - OCZ Mod Xtreme 600W
HDD - 1.5TB
SC - SB X-Fi Xtreme Gamer

Sorry, forgot to add 2 important details.

Motherboard: ASUS P7P55D
CPU Cooler: stock intel cooler (at the moment)

I will buy a new better cooler very soon, won't start overclocking without a proper cooler.

:D 300 quid well spent.

3.6ghz an I will be happy :)

Very nice easy, though get that stock cooler out of the way.:D. Whats your plan for cooling, water/air. Regardless id like to see how you get on.:) ps 300 quid is pretty good, my i7 board, cpu and ram came to about £550.00, the reaper c7 ram was £99.00, a week later it shot upto £150.00, stuck with it as im very fond of the ocz reaper kits, had both pc 6400 and pc8500 reaper ddr2 on s775, ocz is the only ram id reccomend.

That cooler was just in shot.:)

The chip will be going under water. Ok its a C0/C1 chip but I wanted top end at a mid range cost.

I will be happy at 3.6ghz 24/7 but of course will tinker for 4ghz:p

In all honesty this 920 maybe just a transitory chip for when 930 comes mainstream.

But for 100 quid its a lot of chip for the money.For anyone wanting to get into i7 cheap they make good sense.
 
Can somebody check these settings for me as I have my cpu at 4 GHZ at the moment and all seems fine,

AI overclock, manual

cpu ratio 20

Speedstep on

Turbo mode off

BLCK 200

PCIE Freq 100

cpu voltage 1.35

Dram voltage 1.64

Load line calibration enabled

Spread spectrum disabled

Clock skew disabled.

Ram set at 1600 mhz and timing as per spec.
 
Code: 
CPU Clok ratio 19x
QPI Link speed x36
Baseclock 211
Performance Enhance - standard
XMP disabled
System memory multiplyer SPD - 8.0
intel turbo boost - enabled
Cpu cores enabled - all
CPU multithreading - enabled
C1e , C3/c6/c7, thermal, EIST and PROCHOT all disabled
Virtualization - enabled.
Uncore freqency x16
Isochronous supprot - enabled
PCI frequency - 100
CIAZ -disabled
CPU clockdrive 800Mv
PIC Express clock drive 900Mc
CPU cliock skew 100ps
IOH clock skew 0ps

Local-line calibration - disabled
CPU Vcore 1.250V
QPI/VTT coltage 1.295v
IOH Core 1.16V
DRAM Voltage 1.640v

everthing else is as at default / auto

Ram 8-8-8-20-1

thats my settings for 4GHz stable, dont know if there is anything that should be changed though.
 
4ghz needs a lot of vcore although my trusty Apex Kit handles the temps nicely 67c full load

I think the sweet spot is 3.6ghz 24/7 at 1.3ish volts. Needs more tweaking but like I said 3.6ghz is fine for me 24/7 with this chip.
I'm wanting not to get addicted again and really want to avoid the need for a D0 at 4ghz but in real usuage I wouldn't notice the difference. Bargain chip for 100 quid. Can always look at getting a 930 next month but tbh this i7 is staggering.

Note to others. If you want to go i7 and can get a chip for 100 even if its a C0/C1 then you get a blistering fast pc. I worked it out in my other thread.A stock i7 920 2.66ghz is faster than a Q6600@ 3.8ghz.

So a 3.6ghz i7 is uber :D
