Hello,

I want to overclock my Intel Core 2 Duo e4500. I have done so already but I am wondering where I can go up to. Its stock speed is 2200mhz

However in my bios I have changed that to 2529mhz (230x11) as I didn't want to overclock it too much yet.
The voltage its at is 1.552v which Is quite high isnt it? (its set to auto) and the processer runs at about 30-35c.

My motherboard has an max FSB speed of 1600, so as I am very new to overclocking could you help me out here and recommend some settings for me to use please.

The cooling is quite good, it has an akasa ak965 heatsink and 3 fans inside it.

Thanks
 
Anything below 1.3V is safe as far as I know. Is 30C idle??? You could probably push it up to 2.8GHz easily, just try it, watch the RAM, what kind of RAM you have?

I have 2x1GB 667mhz RAM, which is quite slow I think, is there any way I could make the speed higher than 667mhz?

thanks
 
when you overclock the cpu, the ram automatically adjusts itself to match the cpu clockspeeds, however if the ram your using is generic, it could damage the ram. I suggest getting ram with head spreaders on it, and if your mobo supports ddr2 800, get those instead of 667.
 
I hit 3ghz on my E4500.

1.4vcore (totally safe and good temps. 26c idle)
275mhz fsb
Unlinked mode (memory and CPU not linked when overclocking)

I'm going to buy 2x2GB 1066 RAM soon..

What do you mean? My current 667mhz ram is going faster than the 1066mhz.

I overclocked my CPU to 2.8ghz and my FSB is 1020.

Thanks

What motherboard are you using? does it list the FSB as the "QDR"?

If so, set the QDR to 1100mhz, and voltage to 1.4v. I had 4x1GB of memory so sometimes i had issues, but you with 2x2GB will not.

Does your board support unlinked mode?
 
It is unbranded 2x1GB RAM. I am thinking of buying 2x2GB 1066RAM, if I can find some cheap enough.

Does my RAM limit my overclocking much? cheers
 
If you fill all the RAM slots, it will limit your overclocking ability. Please, do yourself a favour and get branded memory. Kingston at minimum. Corsair, OCZ, G.Skill and Mushkin are good, reliable brands.
 
If the memory is on the qualified vendors list (look in your mobo manual or online) then yes it should work.
 
OK, I have overclocked it to 2.75ghz and vcore is 1.325 however when I overclock it to 2.8ghz or above with the vcore as 1.325 it restarts and I get blue screens... My temperatures for 2.75ghz are about 24-27c idle and I left hwmonitor on when playing GTA4 and max temperature was 43c.

As it blue screens when I overclock it to 2.8ghz, does this mean that is my limit, I upped the vcore but I am unsure on that as it just restarted. (I managed to get 2.8ghz before but left the vcore to auto and it was 1.52v, the temps were higher when I set it to that)

Cheers

I'll rephrase that but does anyone know what the VCORE needs to go up by or is it just trial and error?
 
You need higher vcore. at 2.8ghz i needed 1.385v. It is trial and error as each chip is different.
 
you can go higher, but first you need to raise your memory voltage. I'm guessing it defaults at 1.8v (for memory)

What you want to do is take your memory voltage to 2.0v (not your CPU voltage, 2v on a CPU will kill it). keep the CPU voltage at 1.385v when you have done this and see if it is stable.
