It seems that overclocking RAM gives the least performence boost.  Such as doubling the ram speed makes games run 1% faster.  All the big name Ram can run above spec, all be it with added voltage.  I wanted to add that the e2160 cpu can be overclocked from 1.8GHz to 2.8GHz and the e8400 cpu can be overclocked from 3GHz to 3.6GHz without added voltage.  In these situations the cpu temps are nearly identical to stock.

ExtremeFusion, can you notice the overclock on your P4?  Do your programs run faster?

it runs a little faster than before had to go to P4 2.6 OC speed.. i might have messed up with my previous OC..
It fails Prime95 tests

2.6 seem to be stable so far..

Still finding OC tools for OCing my RAM and mid level graphic card..
I like to play with it just before i buy a new rig.. and OC it..

You seem to put a lot of faith in the specs given by a manufacturer, while they really aren't absolute. The Pentium D (two P4s stuck on one PCB) could run at 3.5 - 4 GHz comfortably. Though I should add that if you didn't have a golden sample it'd be using like 200W at 4 GHz, especially with increased voltage. As long as he runs at stock voltage, the increased speed won't add much to the heat output and required amperage.
I put faith in the fact that if intel sells a cpu rated at e.s then that is the speed they will guarantee it to run properly at.
anything beyond that puts it into a state that might work, but fails to meet intels criteria for everyday operation.
I also put faith in the fact that if a cpu will run at a certain speed reliably intel will not rate it at a lower speed, because thatwould cost them money.
as for your example of the p4d, it just shows what I said. you might be able to run a cpu far beyond specs but in your example that would mean more than doubling the thermal load. and that would require some robust cooling to prevent frying the cpu.

and I am jusr cautioning as I would caution someone that told me he was looking to install a large turbo kit on some compact riceburner. yes, it can be done. but it will decrease engine life and heavily stress the rest of the car. it is a tradeoff.

I use Rivatuner to oc my video card You can give that a try, just make sure you DO NOT check the box that says start with windows. That way if your overclock is to much all you have to do is reboot. Also when you OC your video card raise it  +2 and only do the gpu first then do the memory.Make sure you keep a eye on the temperature of the card,It can climb up real fast when you are gaming.

As for the ram leave it alone. You will have more problems then it worth. I OC my X3350 to 3504MHz but my ram is still running 1:1 with the FSB. Click on the CPU-z banner in my sig it will show you my OC. By keeping the ram at 1:1  my ram is actually underclocked it running at 876 instead of 1066. By doing this I was able to tighten the timing from 5-5-5-20 to 4-4-4-10.

How do i check for my GPU's temp?
What program should I use?

@Buntz

You mean I must first OC my GPU core clock afterwards its Memory Clock?

You might want to check out RivaTuner!

Edit: this is the guide that explains it to you.

thanks coknuck

BTW, somehow RivaTuner has greyed out the first option for OCing the Card I can only OC by forceware..
can't get a screenie for now..

I don't use it.I searched and found it though other forums. Did you look at the second link there are 5 pages on how to use it with pictures.

Yeah I did.. gonna try it..

WTF..

My bios doesn't allow me to change Vcore..   tickedoff

Only left to OC is the midlevel graphic card..

Yeah I got an older one Northwood socket 478..

Yes, idle temp for this processor is worst at 40 C.. but I can see that it can handle temp between 50 - 60 C..

Darn it, I can't make it ro run at 2.8 GHz.. now running it at 2.7 GHz..
At 2.8 it fails Prime95 torture test

Darn it, I can't push my 2.4 to 3.2..

BUS:RAM Ratio is locked..

Mine runs on HSF of a Celeron Processor..

Though, those were just the P4s. (Did I mention one ran at 8.2 GHz, using liquid nitrogen?)
Increasing CPU speed results in a linear increase in wattage required. Increasing voltage increases it exponentially.
And I'm afraid your faith in not setting them at higher speeds if they are capable of it... is wrong. In the case of core 2 Duo and Athlons to some extent too, the yields are good enough that too many CPUs end up at the high bin, leaving too few for the cheaper lower bins, which are in fact sold the most. Phenom I'm not too sure about, it's a really really complex CPU, and yields can't be good for it.

If you can put the OCed CPU to good use, then why not?

granted, as yields for the high speeds increase some may end up downgraded... but you have no way of knowing which ones... so you have to go by what the mfr says.
