New at overclocking but want to learn

post #1 of 14
Thread Starter 
Hey I just recently purchased an Intel E6300 Processor with the Asus P5W-DH Mobo, with expectations to overclock the processor to make up for buying an expensive mobo and memory. I'm using the Corsair TWINX 4-4-4-12 DDR2-800 PC6400. I have a general understanding of the overclocking and how the math works etc. etc. The questions I have were about what how much voltage should everything be set to? As I overclock and raise voltage. What should the MCH be at? What should the CPU be at. How do I loosen timings on the ram successfully and how do I tighten em up? I have Zalman cooling on my mobo, the Zalman CNPS9500. I want to run the processor at 7x400 to get a 1:1 ratio with the memory. Anyways can someone give me some pointers on what I need to consider? Everything as of right now is running very cool. Idle is around 29 celcius and load is 35 if even. My case has quite nice cooling as I am running the Antec Ninehundred, so far so good. Also running an X1900XT 256Video memory which was able to OC to XTX speeds easily. No problems there.

Tips will be greatly appreciated as far as where to start and how to do it. My main problem is knowing what voltage is correct, and also knowing how to work with ram timings as the FSB goes up.

Thanks Kevin.

Welcome to the forums.

C2Ds often run very well on stock voltage, so I wouldn't mess with the vcore (CPU voltage) at all until it becomes unstable. The same goes with the MCH voltage. Since you're hoping to run 1:1 with your RAM, simply enter the stock timings and vdimm (RAM voltage) into the BIOS. Do not let the system do timings by SPD; be sure to enter them manually. While the RAM will be underclocked until you reach 400 MHz, you won't have to worry about juggling RAM settings along with the other settings as you work on your OC. If you do end up running the RAM at something other than 400 MHz, you can then fiddle with tweaking the timings and voltage.

Pretty much just start off slowly. Raise your clock speed in 5 MHz increments (though you can get away with 10 MHz increments early on since they OC so well). After each step, run a quick stability test to make sure the settings are more or less ok (you'll need to do a 24 hour stability test to assure your system in fully stable, but I usually save that until I get closer to my goal or if I'm having significant problems along the way).

When you do inevitably run into instabilities, bump the vcore only one or maybe two notches at a time. If more vcore doesn't seem to help, bump the MCH one notch.

Be sure to use Intel's Thermal Analysis Tool (TAT) to check your temps. Every other program I've tried on my C2D was way off (up to 20°C!). Be sure to keep your load temp under 55°C since you're overclocking.

That should get you going. Just remember to take things slow and easy; while it would be nice to jump to 400 MHz in just a few steps, baby stepping it will give you much better results and will give you a much better feel for your system.

K, sounds good I'll start doing just that. What are the stability tests I should be using? I've run S&M and SUPER PI, I can't figure out how to run PRIME 95 though lol. I think that's one of the stress tests if I'm not mistaken.

Hmmm I just downloaded that Intel Thermal Analysis Test and my idle is now at 45 instead of 29 on the Asus AI Booster that comes with the P5W-DH, odd. Guess you were right tho.

Using the Asus P5W DH is there any way of raising the voltage of the MCH in the bios in smaller increments than the ones that came with it? I believe they are in 1.3 and then 1.4 and then 1.5 or somethin like that. Are there any good programs to download to expand the increments through windows? Thanks for any feedback.

Thanks for all the welcomes feel more welcome than some car forums I've been on in the past haha.

Hrm, when I downloaded it, I got it straight from Intel, but I couldn't find it on their site. You can get it here instead.

I don't believe you'll have much luck fine tuning the MCH voltage beyond the levels given in the BIOS except by possibly doing a hardware mod to the board. Most programs that control the components of the motherboard through Windows are far inferior to the tools available in the BIOS, but even so, I have not heard of a program such as what you're looking for. You should be ok with the 0.1 volt intervals, and unless you are pushing your system under phase or other extreme cooling, you won't likely need more than one or possibly two notches of extra voltage.
