Hey

I was hoping for a little help.

My PC has an Intel Core 2 Duo E6300 @ 1.86ghz (original 2006 not the newer version).

I have overclocked it already to 2.73ghz, but would ( for no good reason) like to take it to 3.00ghz.

The multiplier is x7 and the bus speed has been raised to 390Mhz which gives me 2.7ghz. If I go beyond 390mhz with the bus speed then the computer fails to start. I know at this point I probably need to mess with the voltages of the CPU and ram etc

Do you think it is possible to eek out a little more with some memory/voltage tweeks. I have 3GB of ram both DDR2 666mhz speed. I am not sure where to start with the voltage tweeks?

As I write this my CPU is at 50C in a room that is 26 degrees. I do have an after market cooler should I need it.

Thanks

Ryan
 
You are still using your original Intel cooler? You should really install that aftermarket cooler because the heatsinks that come with processors can't really be used for overclocking.

I'd be hard pressed to suggest anything without knowing what kind of RAM and most importantly what board you're using. :p
 
it could be the fsb limit of your motherboard. my old mobo had a limit around there with my e8400. 1ghz is a very nice OC though. :) what are temps under load? also, be sure not to use too much voltage.

Oops sorry!!

Motherboard: Gigabyte G31M-S2L (supposed to be a good overclocker)

RAM:

X1 PNY 2GB DIMM PC2-5300U DDR2-666 (5-5-5-15 3-20-5-3)
X1 Transend JM667QLI 1GB DIMM DDR2 PC2-5300U (5-5-5-15 3-20-5-3)

FSB at the mo is 1560 MHz

Thanks

Idle today in a warm room is 50 degrees and underload using wPrime and SiSoftware no higher than 67 Degrees on a stock cooler. If I put the case fan on its a few degrees cooler.

I have an aftermarket cooler but its about 1cm too tall for my case so should I ever need to use will have to have the side cover off of the case, or just buy a larger case.

Hm. Mismatched RAM modules are never a good thing. Not that it's a bad thing either, but the more capable stick is going to be limited by the less capable one.

In any case, not to discourage this adventure try kicking the multiplier up and dialing the FSB backward. If that doesn't work, whenever you have the time, jot down the OC options for the CPU, NB and RAM and list 'em here, or PM me and I'll help out as best as I can without physically coming to your home and OC'ing the crap out of it myself. :lol:

What case are you using?

Cool, gimme a sec and I'll post up a pic. My case is just a cheap make, Vento!!

PS

forgive my ignorance, whats "NB"?
 
I hope these pics are helpfull? pics taken with c905!

The system memory multiplier is set to "Auto" which is 2.5 times I believe, so I can only take it down to 2.0 which will bring the Memory frequency down.

Here is my set up should you be interested. Sorry about my office mess!!

Alright....

Don't worry about the PCI-E frequency - leave that on Auto, you should only ever mess with that if you're on a benchmarking binge.

The thing about overclocking is in almost every known situation you're going to have to make a compromise with either your RAM or the CPU (depending on which you want to overclock), and seeing as you want a bit more from your CPU you might have to put the CPU and RAM on a divider. DDR2, depending on the manufacturer, can operate at voltages of 1.65v ~ 2.10v+, so do a little research on your RAM and see what voltages they're most comfortable with. I wish you had snapped a picture of all of the available voltages available to both the CPU and RAM, but I'm fairly confident you won't need to overvolt much (if at all), but be prepared to as I'm suggesting that you bump up the multiplier.

Also, check for a parameter called 'PCI Spread Spectrum' or 'Spread Spectrum' and disable it, it'll only interfere with everything. I don't remember where it is, but check Advanced BIOS first.

Cool, I will have a look and snap another pic for you. Thanks

The stock Intel coolers are capable little things, don't look down on 'em. Of course they're not going to be as good as some of the better HSFs out there, but my stock cooler coped with a quad that was clocked at 3.6GHz. That's all I'll say about that. :lol:

Alright, so whenever you start the fun be sure to overvolt to 2.81v, but only when all else fails. As in, the PC won't POST after you've bumped the multiplier up....and be sure to test for stability using Prime95, Linpack, or the Intel Burn tool (I forget it's actual name, but it's more strenuous then the former two, and will really heat those cores up).

Since my 46% overclock The CPU does not really run any hotter than stock, maybe a fraction.

When you say 'overvolt' do you mean up the CPU voltage to 2.81V?

When I first started to mess with overclocking my system, when it crashed on me it would normally reverts back to stock as a fail safe, though once it would not start up at all so I had to whip the battery out of the motherboard to reset it! lol

These are the below voltage settings used from the Tom's H article. of coures my system/components are different and that overclock is higher. Could I still start with similar or slightly lower voltage settings then the below? And whats MCH?

DDR2 Voltage +0.6 V
MCH +0.55 V
FSB +0.3 V
CPU 1.4 V

Also, what would be the first voltage tweek to alow me to go beyond 390MHZ Bus speed or does it not work like that?

The MCH hub is Intel-speak for Northbridge. If you still want to up the FSB without increasing the multiplier, then by all means - have at it. But overvolting the MCH will be necessary as you're asking it to do more work at a faster clock speed.
 
Running an idle speed of 50C... You've got no more room to Overclock. Only like 15C to play with, that's nothing. You're already loading at 67C. Which is too high in my opinion unless you like buying CPUs every year.

Although 3Ghz is a nice number at this rate you'll cook your chip trying to do it, especially on a stock cooler. And gain over 2.73 will be pretty minimal.
