hi

My rig: q6600 2.4ghz (g0 step)
p5n32-e sli plus (EDIT: 'nForce 650i SLI SPP chipset')
4gb 800mhz ram
8800gts (g92) 512mb
580w hiper psu
Arctic Freezer 7 cooler w/ Antec 900

were first time overclockers and were having a few problems;

set the fsb to 1500 (4x3.75)
set the fsb and ram to linked with 1:1
set the mutlipiyer to x8

then tried each of these power increments
stock - 1.248v
increased and tested:
voltages tried:
1.2937
1.3***
1.45000
1.60000

Not getting anything just black screen from power on.
any ideas/help? thanks
 
hey thanks for the reply, just been trying the stock to 2.7
went as far as 1.75v still no post. the only difference is
my ram is 1:1 also my bios only lets me set the fsb all at once
e.g. u say 300, i do 1200.

Any other ideas? this mobo is just /grrrrrr
 
update:

had the multiplyer on 8 when I tried the 2.7 clock
so it was infact 2.13ghz and it still didnt post with 1.3v
then set the mutliplyer to 9 as you say to and still no post

shall I just give up and install runescape? :S

(using cpuz i can see that my fsb: dram ratio is 2:3 shall i try this timing when oc'n?)

Tis simple.


The board is mostly based on the 650i chipset, and it won't exceed 333mhz/1333mhz FSB with a quad-core. So I've really no idea why you're dropping the CPU multiplier as you'll need it set at the max (x9) to get any sort of an overclock out of that board.
 
You shouldn't really need to touch the CPU voltage as most Q6600's will do ~3ghz on stock volts. Unlink the memory and set it to 800mhz (remembering to set its correct voltage if it's more than 1.8v).

To get close to the 3ghz mark you'll need to pump a fair few volts through the MCH (northbridge) as that's what is holding you back. A small fan over the northbridge would be a good idea if you start pushing high volts through it.

I'm not really familiar with the nVidia BIOS, so there may be a couple of other options you can fine tune. There's a huge ASUS P5N-E thread somewhere in the bowels of the Motherboard forum, and whilst it's not the same as yours, it shares a heck of a lot of features with yours. There should be some good info in it, but nothing that will push you past 3ghz.
 
1.6 is way too high, why did you then go to 1.75???? you're going to kill it if you havnt already!

welcome to the noob dilema... don't wanna ask nab question because you tend you get a lot of replies with minimal questions answered and there's traditionally a high level of sarcasm.
So you decide to try it yourself and make studid mistakes like I'm guessing
I nearly fried my pc lmao :P

il try find that mobo thread :/
 
Did you actually read any of my blog which I posted for you?

Each one has a summary of the changes I made so following these should help you but do it progressively.

for example, to get to 2.7GHz apply the following changes and test:

JumperFree Configuration Settings

AI Overclocking: Manual
FSB Frequency: 300MHz
PCI-E Frequency: 100MHz
DRAM Frequency: 720MHz (5:6 asynchronous)

CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled

CPU Voltage: 1.3v



then for 3GHz as above but with:

JumperFree Configuration Settings

FSB Frequency: 335MHz

DRAM frequency : 804MHz (5: 6 Asynchronous)





went as far as 1.75v still no post.

Proof you are not reading the posts.. I had already said that 1.6v was too high !!

Wow, 1.75v is really high on air, never mind a freezer 7. As previous poster said, you need to read what people are posting.

I personally don't recommend going above 1.55v maximum on air, unless you've lapped your cpu and/or cooler, or just don't care about your cpu's life.
 
Not sure how similar yours is to the 680i but there's This link that is OCing a 680i with a E6600 and gives a load of things you need to disable in BIOS before trying the OC (unsure about the rest of info there, maybe worth a look). things such as:

CPU Thermal control - disabled
C1E Enhanced halt state - disabled
Intel Speedstep - disabled

CPU Spread Spectrum - disabled
HT Spread Spectrum - disabled
PCIe Spread Spectrum SPP - disabled
PCIe Spread Spectrum MCP - disabled
Sata Spread Spectrum - disabled
 
OK, my n00b comments from reading here and there:

set the fsb to 1500 (4x3.75)
set the fsb and ram to linked with 1:1
set the mutlipiyer to x8
As someone stated you'll need to stay at x9. Also you want to up the FSB in increments to be honest, maybe 20 to 40mhz at a time or something to see when it starts to become unstable.
then tried each of these power increments
stock - 1.248v
increased and tested:
voltages tried:
1.2937
1.3***
1.45000
1.60000
The article I linked above says to up the voltages on various stuff before trying to increase the FSB, then once you get a stable running PC, lower the voltages down slowly to as low as you can get and be stable (in order to bring temps down). Pretty new to OC myself so maybe someone else can comment on this way of doing it? The only time I got a no post was when I forget to increase the voltage from AUTO before increasing the clock. Or I had the RAM settings wrong.
Not getting anything just black screen from power on.
any ideas/help? thanks
Are you able to get into BIOS by continually pressing the DEL key after hitting the power button?

You may want to try unlinking the RAM I think? Does your PC post and go into windows at stock speeds?

why do people still post turning off CPU Thermal control, with the voltage the OP put through his chip it would be fried with Thermal control off.

Turning it off makes absolutely no difference to an over clock, but will save it at high temps.
 
Hmmm, thanks, I may turn mine back on then as I wasn't sure what it did, I was following that OC article. So what does thermal control do, stop your machine at a certain temp or something?
