Today i built my first computer! and i was wondering if i could overclock my E2140 and i searched on the forum and found people were having great reslults overclocking with stock cooling. and i read that VERY info packed guide [props to who ever made it] and when i read that part about the ram and FSB i dont know how to tell the speed of my ram ,i have dd26400 crucial. and can someone tell me where to find the max voltage for E2140, it wasnt on the link that was in the guide. and can somone like if theses are right.
200x4[intel] = 800
FsB = 200 Mhz
First i changed the multipliyer? from 4 to say 5? not exactly sure waht the first step is.

Firstly, congrats on your new build! :beer:
Next, 200 x 4 is the FSB. This is NOT the CPU clock speed. 200 x 4 =800FSB. The value of 4 cannot be changed because its the way it is (Intel FSBs are quad pumped).
The CPU speed at stock of your E2140 is 200 x 8 =1600Mhz (or 1.6Ghz). Eight is the multiplier and is a value that can be changed. This value I believe ranges from 6 all the way to 8 for the E2140.
In order to check the speed of your RAM, you should download CPU-Z (http://www.cpuid.com/cpuz.php). It gives you a lot of handy information about your computer including RAM timings, RAM speeds, CPU clock speed, motherboard chipset, steppings, etc..
Your RAM is most likely running at an effective 400 MHz right now (200 x 2).
The first thing you want to do when you are overclocking is to lower the RAM speeds by changing the FSB: DRAM ratio. This setting can be found in the BIOS of most modern motherboards. This allows you to overclock the FSB with the RAM limitations out of the way. So just continue to up the FSB until unstable. Than change the ratio back to 1:1 and fine tune the FSB to suit your RAM limitations. Make sure you watch temperatures using programs like Core Temp or TAT (google them if you don't have them). Only up voltages when you are unstable and do not do it excessively either.
Any further questions feel free to ask. :)

wow this is a great forum, slight diffrence tho. i got 800mhz ram [under cpu only comming up at 400] why? and i have a abit ip35-e. so should i go in 5 mhz increments? or waht my main goal is to get 2.0 GHZ stable

CPU-Z shows 400 mhz memory speed because 400x2 = 800mhz, the speed of your ram.
also, with that cpu, you should be able to easily hit 2.0 what might be a better one to shoot for is probably 2.6-3.0
Id say go for the big one all at once, set your ram timings for 5-5-5-15, the rest aren't super important at the moment, bump the fsb up in intervals of 5 till you reach your wanted speed. If you are only looking to go to 2.0, you shouldnt have to mess with any voltages except memory which should be set to 2.1V
if you want higher, keep bumping up the fsb. If you experience hangs, as said before, bump up the voltage a knotch, but don't go to far, voltage = heat and on stock cooling, it can all add up very fast.
someone correct me if i'm wrong in any of these areas. :thup:

Well on an e6300 on stock cooling build I did last Winter I was actually able to go higher w/ less voltage b/c heat was an issue even at the default voltage.
Make sure you find out what all your voltages are supposed to be and set them manually, so that they aren't automatically ramped up as you OC.

i was looking at my voltages on abit eq and it said the max voltage foor my ddr2 is 2.04 and i cant do 2.1 like you said. and the voltage on my cp is 1.22 and is running at 50c. 2.6? :-) but those ram timmnings all i have in my bios is a ratio and its set at 5:6 which seems weird i thought it had to be 1:1

It doesn't HAVE to be 1:1. It is whatever you set it to, or whatever is automatically selected by the BIOS if you have it set to AUTO.
I don't like those Windows based OCing programs. I like to do it old-school and do everything through the BIOS. I recommend you do the same if it's feasible.

is that 50C load or idle?
If its load, bump to 3.0 and enjoy, youll be getting around the same temps as everyone else, probably roughly 30-35 idle and 58-65 load.
Agreed with Jason4207, do it through your bios, the programs just don't seem that great to me considering ballistix are rated for 2.1V and up your VCore to 1.325 as you can see here, another member reached 3.0 with that processor and stock cooling just fine.

Your max voltage for your RAM should be determined by the company that makes the RAM, if you purchased it off of newegg I know they usually list the latency of ram along with voltage, if you're still uncertain check the manufacture website.

i got "DDR2 2GB PC6400 DUAL OCZ" [http://shop1.outpost.com/%7BC8LEsQMFg97N7QxMvhjajQ**.node3%7D/product/5283407?site=sa:Hard%20Drives%20Memory:Spot4]
# 800MHz DDR2
# EPP 4-4-4-15
# 2GB (2x1024MB) Dual Channel Kit
# Unbuffered
# OCZ Lifetime Warranty
# 2.1 Volts
and you stated a diffrent epp?? is tehre way to change it?
i upped it to 2GHZ through my BIOS and when windows was trying to load it just said some file is corrupted so i put it down to 210 x 8 = 1.68 and it booted just fine, and 45c idle and it went to 80c on load. i used occt to make it go to load. it seems my processer gets hotter than others, i even bought premeium thermal paste like the guy at frys told me to do.

How good is the ventilation in your case? is it really stuffed up or do you have a few fans moving air through it?
80C under load at 2Ghz seems like ALOT to me...
And if your memory is rated for 4-4-4-15, use that.

80* is way too high. What program are you using to monitor temps? CoreTemp is the one you want. I wouldn't trust anything else.
You may need to re-apply the paste. Did you get Artic Silver 5 (AS5)? Make sure you use 90+% alcohol to clean the surface of the Heatsink (HS), and the CPU before applying the paste. Go to AS's website (if you got AS5 anyways) and read on the correct way to apply it. Too much is not good. I always end up putting too much at first, and then after the 2nd or 3rd time get it right.
Also to make sure your HS's pins are lined up right so that all 4 tabs click when you push them through the MoBo.
Also when OCing if you suddenly hit a wall of some kind memtest can help you determine if it's the RAM holding you back. If your RAM passes w/ no errors then it could either be your MoBo or CPU. Drop your multiplier, and if you still hit a wall it's your MoBo. Up voltage going to FSB, NorthBridge, or SouthBridge to overcome this. Up voltage to your CPU to overcome CPU wall (You need to be careful w/ this one since you're on a stock cooler...you may actually want to lower this voltage to keep your CPU from getting too hot). If your Memory is holding you back loosen the timings or increase the voltage to it.
Your EPP is the RAM timings that a small ROM chip on the RAM tells the system to set it to to run at spec. You can change your RAM timings, but the EPP is hard-coded. Once you turn off the AUTO setting for RAM the BIOS won't use the EPP, but will instead use whatever timings you tell it to.

that was load for 1.68GHZ it wont boot up for 2ghz i will try reapplying it.

ok so i reapplied the thermal paste and its running at liek 40c idle acroring to coretemp and when i try and boot past anything 2GHZ it just says i need to reinstall windows, so i clocked it to 1.76 and it boots fine. what shall i do?
