Hey All,

Well this is my first post in here and hope you guys will be kind to me. I am new to overclocking. I have just built my own pc and im very proud of it but i want to try and over clock but im lost in where to start. I have read the guide on here hundreds of times and understand somethings on it.

But i need help starting the whole Overclocking thing.

My CPU is: Intel E6600
Ram: 2GB Kingston HyperX 6400 DDR2 800mhz
Motherboard: Asus P5N-E SLI
Power: 500w

I get into Bios and i have read on her in the forums that its best to set the FSB and Ram to 1:1 ratio . Does that mean setting the option in Bios to manual for fsb and ram and change to 1:1. What does linking and specific mean do i need to do anything there instead? when i tried the option without over clocking the 1:1 option sets the ram speed the same as fsb @ 1066 is that ok if the ram only runs at stock 800mhz? or am i in a tottally diff ball park..?


I need help to get the settings correct to get a start.

Am i thinking correct that once fsb and ram is set to 1:1 you just raise the FSB 3-5mhz a time and test.

What temps should i be worried about at the moment using core temp its 29c and 33c. have 4 fans in my case plus the stock cooler.

God im lost and want to get my mind straight and get started. but i have read so much and im now tottally confused in how to start.

Hope for some help? Sorry i bet this has been posted alot of times but i cant seem to find the answer.

Steve

Doesn't sound like your lost. So far your temps are fine; if your 100% load temps get past 60c back off a bit. Use Orthos to get your load temps and test for stability.

What cpu cooler are you using?

Im Using the Stock Cooler. So am i correct in setting the settings to 1:1 so the ram goes to 1066 like fsb? then start overclocking? I am a little lost as i want to get started. and need a push in the right direction.

With your ram that's a good place to start. Definetly move slowly; with a stock cooler your OC is limited by temps. Good luck. Keep posting qustions. You will need a better cpu cooler for a high overclock....

If you deliberately underclock the RAM, you can find the CPUs max without the RAM interfearing. Then work up the RAM.
Just one method

Hi.


This is a picture of the Advanced Tab in the 0711 BIOS for the P5B-D motherboard.



The heading that reads "DRAM Frequency" is where I am able to make this change. Since you also have an Asus mobo, yours may be the same or similar.

It is recommended that you take caution when overclocking with the stock cooling. There are instances where people have done very will with the Intel cooler, but aftermarket cooling is recommended.

Your current temperatures are fine... better than fine. Remember that the temperature will be effected by the ambient temp and the VCore that you are using.

As a point of reference: My ambient temp in the afternoon is around 30-35C. I idle at 42-45C, but the Delta (difference between idle and load) is only about 5C... I hate Summer (lol, j/k).

Your temps are fine.

If you go unlinked what would you set the ram too? with my ram kingston hyperX 6400 ddr2? MY FSB at present is 1066mhz so what figure would i put in ram before i start to change fsb?

Thanks for the help so far..This is a great forum.

If I am interpreting your question correctly, I would try to keep the ratio at 1:1.

Your setting would be at 266 (quad-pumped: 4 x 266.5 = 1066)

Your CPU should be 9 x 266 = 2394 MHz

You could always advance the RAM as the stock MHz is 400

Ok cool.. Syrillian

Ok so i get this right this would be settings..
Unlinked ram and fsb
fsb = 1066
Ram manual set too 400mhz ( am i correct in saying that)

Then i just increase the fsb 3-5mhz at a time.

Am i correct in the above ?

For a rated FSB set to 1066, your RAM would be set to 266 (266[.5] x 4 = 1066)

Take a look at the picture that I posted. You will notice that my FSB is set to 440 (3.52GHz clock speed). My rated FSB is 1760 (4 x 440).

This means my RAM is running at a 1:1 ratio of 440 (880 effective).

There are a few methodologies that are followed when determining the highest OC that a system can take. Temperatures and VCore not withstanding (though vital), most people will OC the CPU and the RAM sepeartely to see what each of the elements can take, then tune from there.

Since you RAM is running under spec, you could leave the RAM at auto, and push the CPU (you have a 133MHz window to play with [400 - 266 = 133 +/-).

In the advanced Tab change the CPU Frequency setting at 5MHz increments, and re-boot. When the system fails to Boot, or becomes unstable start to up your VCore. The thresholds for Voltage and temps that I use as a rough guide for the top-end settings on my Allendale are:
  • VCore = 1.40 (after droop)
  • Temp = 55-60C (Load)
I generally do some stability testing every 20MHz or thereabouts (3DMark06, Games, Orthos, TAT, etc...)

So:
  • Leave RAM at Auto.
  • Raise CPU frequency by 5MHz
  • Stability test every @ 20MHz increase
  • Monitor temps (<55-60C) and be aware of the VCore (<1.40).
I would recommend that you download and use Intel's TAT (Thermal Analysis Tool) to monitor your temps
