Hi, my system is listed in my sig. This is my first self-built pc, which i did a few months ago, with help from you guys . Now, I am a complete newbie at overclocking. Right now, I am using the stock cooler and settings for my cpu. I would like to get my cpu to about 4.0ghz stable, using only air cooling. I would like to know: 1. How many case fans do i need? I have a case with slots for 2 90mm fans on the back, and one on the side. I currently have only one fan installed. 2. what PSU and wattage are required? 3. Which kind of CPU coolers would you recommend, and what are the criteria for a right CPU cooler, for a e8400 at 4ghz? How will i know if it will fit in my case? 4. Assuming I will get the right parts at newegg, how do I start overclocking, since the multiplier is locked? 5. anything else i need to know? any advice would be heartily appreciated. Thanks!

I have one of the new direct touch heatpipe coolers on my E4400 stock 2.0Ghz overclocked to 3.2Ghz. It is here. I got it at the egg while on sale and paid about 35 for it. It comes with a nice 120mm fan and it's installed so it blows the air to the back of the case. http://www.frostytech.com/articleview.cfm?articleID=2233The Maxtor PATA drive you have which is a 4200RPM drive would be better replaced with one of the new SATA drives with 32Mb cache like this one. http://www.newegg.com/Product/Product.aspx?Item=N82E16822148288The P35 chipset is a great overclocker. The easiest way to overclock is to increase the frontside bus speed FSB. The way your CPU is set up is the FSB times the multiplier equals the speed of your CPU. Your multiplier is locked on the CPU. So you can't just increase the multiplier. But you can lower it. That is what Intel speed step does. Some motherboards do not report the true FSB in the BIOS, like my ASUS P5N-3 SLI. It shows the FSB as if it's already quad pumped. So when figuring the true FSB, you have to divide the figure by 4. My E4400 runs stock with a 10 multiplier at 200. This figure shows in the BIOS as 800 since they apply the quad pumped figure. So divide the 800 it shows in the BIOS by four and you come up with 200 times the 10 multiplier equals 2.0Ghz. To run my CPU at the 3.0Ghz. I just leave the multiplier at 10 and set the FSB as it shows in the BIOS to 1200 and there it is. Divide 1200 by four and it equals 300. 300 times multiplier of 10 equals 3.0GHZ. The hard thing about overclocking is you memory is on the same FSB as your CPU. So if you leave it at the same speed as your overclocked CPU, the system will not boot. So most of the motherboard manufacturers have what are called dividers. So you must set your system RAM to run at a slower speed. It's usually like 5/4 or 5/3 or some other combination. I would just go here and read up on the P35 chipset. http://www.overclock.net/intel-motherboards/254734-gigabyte-ga-p35-ds3l-thread.html

thanks speedbump! now, since my mobo, which is a GA-P35-S3G, supports up to DDR2-1066 speeds, does that mean that if can set my CPU FSB at 1066? The help you provided was very good, but the link doesn't open...?

hmm...how do you lower your multiplier when its officially locked by Intel?

hmm. 3000mhz divided by 9 is 333.33333333 . but officially, the e8400 is rated at 1333mhz FSB. this does not round out...

sorry for being a pest with so many questions.....
so in my instance, when do i decide to lower the multi? is it when i encounter a hole in the mobo only?
how can i calculate the Power requirements? i think that my antec 550w will not survive 4ghz...

I run my CPU, a Core 2 Duo E6850 (3Ghz) at 3.8Ghz with the vcore at 1.36v Maximum vcore for a E6850 is 1.5v Just to give you some idea. Best regards, Kodiak.

4.0Ghz is pretty ambitions. I know e8400s will go there, but you will have to add a LOT of voltage to go from 3.6 to ~3.8, and a LOT more to go from ~3.8 to 4.0+. As someone says above, your components die faster. But probably not inside of 5 years, and most of us won't be using the same parts by that time. For 4.0, Most guys end up with ~1.4v on the e8400, but that is above Intel spec so they must have some very good cooling. What kind of cooler are you using on that CPU? If you haven't decided try either a Zalman or a direct contact heatpipe Sunbeam cooler from Newegg.com. You're talking $40-60. Use arctic silver 5 thermal grease. By the time you are done, I'm guessing you are going to have to increase your CPU, memory, Northbridge, and FSB termination voltage. OC'ing is not dangerous so long as you know your hardware's outer limits. I would recommend you consult someone before you start to make sure you don't sizzle your brand new equipment. Clock speed is fine to experiment with, if you take it slow; voltage, not so much.

Just remember for stability for overclocking, you must disable the built in Intel speedstep in the BIOS. There are two settings that have to be disabled. One is CIE and I'm not sure what the other is. I think one is "Speedstep" and the other "C1E" (not CIE). However, different motherboard manufacturers may use different terminology for these things.

A question from the gallery... Do you guys who overclock run that way full time? Or do you drop to stock speeds except when you need the performance? Are these PC's run all day or only when needed?

thanks for the suggestions. Looking from your comments, I think its best for me (since im a newbie) now to just leave the voltage alone, and play with the FSB around abit. luckily i found this article, just in time:
http://www.tomshardware.com/reviews/overclocking-software,2059.html
a few more questions still linger in my head:
how can I make an informed decision on what cooler is best for my overclocked CPU? I know Phoenix talked about a Zalman or something for a suggestion, and speedbump mentioned a link above. But different clock speeds require different ones. So how, on my own, do I decide a good cooler (not that I don't want to follow your suggestions, its quite opposite, I just want to be able to form educated decisions of my own in the future) for lets say, 3.5ghz? 3.8ghz? etc. ?
What is a direct contact heat pipe? whats thermal grease?

Thermal grease is known as TIM or Thermal Interface Material. It's the white or gray goop that fills in the voids between a heatsink and the heatspreader. Thinner is better when it comes to TIM. Proper TIM application makes the difference between having a cool running proc and a smoking one. Everyone has their favorite TIM though. The best place for heatsink tests are at Frostytech. http://www.frostytech.com/top5heatsinks.cfm
