Hi, need some help as I've not oced before and want to get more out of my system.

My system:

Vista Premium 64
ASUS P5K-premium
Intel Q6600 (2.4 x 4 ghz)
Arctic Cooling Freezer 7 Pro
OCZ 8GB (4x2GB) 1066MHz Reaper HPC Edition
Sapphire ATI Radeon HD 3870 XT "Toxic Edition" 512MB GDDR4
Creative SB X-Fi Platinum Fatal1ty 7.1 Champion Series
550w PSU
Antec P180 Case
Samsung SM-2493HM and SM-226BW

CPUz readings:

Firstly, how do I get my ram up to its max speed (1066) as it is currently reading at just 400.9?

Secondly how do I go about ocing my cpu up to around 3.00 Ghz? I do a lot of rendering in rhino and maya so more speed would be nice.

Thanks in advance.
 
Thanks, will give it a shot. You do have a really similar rig lol!

What speed did you get your ram to run at? From reading this forum I'd have to set the FSB to 533 to get it up to 1066?

Like I said, I'm pretty new to this so some people may tell you otherwise...

These are my settings though.

Ai Overclock Tuner - Manual
CPU Ratio Setting - Auto
FSB Strap to North Bridge - Auto
FSB Frequency - 370
PCIE Frequency - 100
DRAM Frequency - 1007MHz

CPU Voltage - 1.325
DRAM Voltage - 2.10

Everything else is set to auto and I seem to have it stable after several hours of prime95 stressing :)
 
Some settings for you to try:

multipler 9
Strap 333
FSB 400
Pcie 100
Dram 851
Command rate 2n
Ram 4/4/4/12/4/25 everything else auto
Dram SRC auto
Transaction booster level 0
V Core 1.525v
PLL 1.5v
FSB TV 1.30v
NB 1.40v
SB 1.05v
Cpu spread spectrum disabled
Pci-e spread spectrum disabled
Clock over charge auto
Load line calibration enabled
CPU GTL auto
NB GTL auto

If you can get 3.6, do a 8 hour prime and then slowly lower your PLL and vcore.

Finally got round to trying to overclocking now my work is all done and doesn't matter as much if I crap up my pc. I put in these settings, didn't give me the option of 1007 for DRAM though I think I had to select 986 as closest. I ran prime95 to check the settings were working on cpuz and it doesn't look like they are. Cpu core speed only 2220 and cpu voltage at 1.28V not the 1.325 I entered. DRAM freq still only 493.3 too. Any ideas what is going on?

Also what is the need for the PCIE freq at 100? Can I just leave on auto as I don't need to oc my gc or sc?
 
ok i just set everythin back to auto except
ai oc: maunal
CPU ratio: 9
FSB: 300
DRAM freq: 1001


I'm just trying to see if it will oc even just a small amount before pushing up to 3.4ghz. Every time i've changed the settings in bios the computer turns off and on then just does nothing like it sometimes does after a restart. I then have to unplug the psu, wait for all the lights to go off then plug it back in. I then turn the system on and it comes on for a second before restarting again and boots up. Is this normal?

ok the above config i just tried seems to be working fine. finally cpuz registers over 2.4! running at 2.7 no problems yet. dram freq still says only 500MHz though in cpuz... is that a problem?

edit:
hmm after a few mins stress testing it dropped back to 1.8.... wtf going on?

You did turn off speedstep and the other power saving bios features yeah?

Not touched any of the other BIOS settings since I got it so if they are on by default then then will still be on. What problem would they being turned on result in? I'm a novice with BIOS settings really, never touch them normally.
 
I dont know what it will be called in your bios but it is called intel speedstep in my bios. You need to turn it off so your CPU doesn't drop down from your overclock.

With your ram speed, it will say 400mhz in CPU-Z, that equals 800mhz (ddr2 - double data rate). So for your ram to run at its spec then CPU-Z will need to say 533mhz (x 2 = 1066mhz).

I hope that makes sense.

aaahhhh i finally get it lol! thanks for that, makes so much more sense now! Will try disabling the speedstep now

What will a different ratio result in given a proportional change to the FSB? I mean if i have the ratio set to 9 and the FSB at 300, what is the difference compared to a ratio of 6 and FSB 450 as both result in a core speed of 2.7.

ok i'm getting some ridiculous temps on the cpu and mb when i oc so i put back to stock. when oced to just 2.9 the cpu is at 80°C! Seems way too high as i'm using an Arctic Cooling Freezer 7 Pro. Not sure what is going on!
 
Tim applied proper? Concave cpu or hsf? Bad airflow in case i.e loads of wires all over the place etc.

Also make sure you dont put the cpu volts too high 1.4 max i would, should be 1.3 for 3.2ghz i think is doable from what i have read.

Also if you mean multipliers like 9 (the multi) x 300 the fsb, then the less multi then the higher the fsb but its taxing the mb and parts more the lower u go. Generally just notch down one from the highest multi if ur highest isnt stable but next one down is.

must be the cables... i'll check the processor tomorrow for concave but it was fine when installed. will re-apply the tim too and try and sort the mess of cables out (installed new psu today so cables aren't too tidy yet)
 
I've noticed the P5Ks are randomly flaky when it comes to pc2-8500 memory. Remembering too that the memory is unofficially supported hence it's name "overclocking" RAM. That said, I flashed a P5K deluxe last week which got the 8500 RAM working at full speed. I've no such luck with my P5KC which hates it :(
 
yeah i might trying updating bios to latest. I'd read online that the newer versions still had problems though and earlier versions were better for ocing.

edit:
just flashed latest and still doesn't reboot properly. had to unplug psu like before.
