I know many of you out there are proficient in teaking your system to maximize it's capabilities. I have thought about overclocking my Intel E6750 processor, but don't want to screw it up. How do you do it?

I overclock my E6750 (at 3.4ghz) and can tell you exactly what to do if you have the same motherboard, RAM and cooler as I do.
They're all interconnected when you overclock.
For e.g. pushing the CPU up will push up the RAM speed too unless you limit the RAM clock.......

I read forums like this to get general hints and tips.

Lots of people on this forum are overclocking their E6750 to 3.6 or more. However, 3.2 can be achieved very easily without messing with any voltages or other potentially risky functions.


Here's the simplest and safest way to 3.2ghz.....
A very simple over clock for ur Spec will be:


Before overclocking
Disable All CPU features like Enhanced Speed Step, C1E(Enhanced Halt State), TM2....Etc


Set Vcore to manual and set it to about 1.25 volts (Standard Vcore for ur CPU)


1. Lower the DRAM frequency to 667MHZ from 800Mhz so it will be FSB:RAM=1:1


Update : Set ur PCIe frequency to Manual and set it to 100MHz just to be sure it wont go high and do Video card Probs


2. Increase the FSB to 400MHz from 333Mhz(your stock speed) dont change the multiplyer leave it at 8 or Auto.
When you do this ur DRAM frequency will increase to 800MHz so itll be running on stock speed, No OC on Ram


3. And u got a overclock of 3.2GHz

There is no reason to overclock an E6750 except for Crysis. However, they are essentially begging to be overclocked.

Eamo has it right, but he neglected a couple of things.

The overclock he described is painless and a risk without thinking of cooling. Everyone wants to overclock, but nobody wants to open the case and pull a couple of things apart or even put in some fans.

The CPU temps may be alright (w/o a voltage increase), but the Northbridge temps will climb fast. Active cooling on the Northbridge (a small fan can be bought easily), a third-party cooler for the CPU (Zalman) or at least get the crappy thermal pad Intel uses off the stock cooler and get some decent thermal paste under there.

Finally, get some 90+mm fans to keep the case cool, but still reasonably quiet. Bigger fans move more air at slower RPMs, so bigger is better. Typically, an ATX case can do 80~90mm fans. Get the pliers out.

Eamo, I know you have a Zalman and am not saying you are a lazy overclocker (I know you know your stuff!), but when spelling it out for a novice, cooling can not be overstated. IT will make or break even a small overclock and without proper cooling, heat can cause parts to have a much decreased lifespan....much decreased.

A very mild overclock can be done with all stock coolers and no extra work, but certainly no more than 10%~20%, IMO (Yes, a wide variation: buying a CPU is a lottery, unless you shop with fabs, S-specs and production serials in hand). After that, one has to really do some work to keep the system stable and alive.

Also, consider power. Overclocking requires more juice for everything. Additionally, be aware of RAM latencies and decreased speeds for stabilities' sake. A modest overclock may ask cheap RAM for a division (ratio clock) or even a decrease in speed, which may actually, in some scenarios, negate the overclocked CPU.

Thanks for the input eamo and Demophobe. I'm thinking it would not be worth the risk at this time, maybe somewhere down the road. At least I have an idea what to do now. Thanks again!

I got my E4300 o/c'd from 1.8-->3.0 on stock cooling! 55 degrees when play high-end games. Apparently, if you have a good cooler (like eamo's monster) you can o/c it to 3.45 quite easily. Best overclocker I've ever seen and a heck of a value. Although 55 is a little high, its not constant...and who cares if your CPU only lasts 3 years instead of 6. If you're an o/c'er you'll be upgrading long before that.

Here's a link:

P.S. I've been o/c'ing forever. It's very hard to hurt your CPU unless you have the cooling installed incorrectly. All modern CPU's will automatically shutdown before blowing up. Don't worry too much, but monitor you temps with Speedfan or the like.

[esetters21]

Alright, I'm ready to take the plunge. If anyone can help me in a step by step fashion using "layman's" terms I would deeply appreciate it.

cooling: stock cpu fan and case fan (no additional cooling)
processor: Intel E6750
m/b: Intel DG31PR
ram: Samsung ddr2 pc26400 x2
power: Solid ATX 400sw

What else do I need to mention? I am honestly clueless here about the whole o/c'n thing even after doing some research. I don't realistically even know where to begin. Sorry for being ignorant here, please help!

OP, did you even check the link I provided? It is specific to the 4300 but general enough to give you some o/c'ing basics. Further, there are hundreds of step by step tutorials for this on the internet. Google it. It would take a lot of time and effort for a helpful poster to go over all of the specifics with you, and it would be a waste of time since it is readily available on the net. That's how I learned.

Try Googling your specific setup: overclock e6750

I did and found a ton of results. Better yet, do some research on overclocking-specific forums such as http://www.overclock.net Do some reading and come back with any specific questions you might have.
