Overclocking E6600 on Gigabyte EP45 UD3LR

[WingZero30]

Hi guys I really need your help as I am new to overclocking CPU.I have Corsair DDR2 800MHz Gaming memory.
I am trying to overclock my E6600 to 3GHz for now which I presume is moderate overclocking from stock 2.4 GHz. So this means I would need to increase the FSB to 333 from 266. OK so yesterday I was looking forward to it when I realised that I am finding the MB intelligent tweaker (M.I.T) confusing.

So far this is what I changed in M.I.T:

-I changed the CPU Clock ratio which I presume is CPU Multiplier to 9X (max).
-Enabled CPU Host Clock Control and stepwise increasing FSB by 10MHz. So currently CPU-Z is showing 276 MHz and DRAM Frequency is 414.0 MHz. The FSB to DRAM is 2:3.
-Set PCI Express Frequency to 100MHz. However I don't see the option of setting PCI frequency.

Rest of the stuff I just left it as it was. So the 'Robust Graphics Booster' is still on Auto and the 'Performance Enhance' is still set to Turbo. I was reading the overclock guide and it says that the memory divider should be set to stock or lower. So I gather that while increasing FSB the DRAM Frequency should be set to constant 400MHz stock value. However I don't know how to keep the RAM to stock value. Also how can I get FSB to DRAM to 1:1 or is there any benefit of doing so?

Finally how much my RAM can be overclocked before it becomes unstable or damaged seeing it has already increased to 414MHz?

Please help guys

There is no need to change PCI frequency and RAM is damaged by raising the voltage, not frequency.
The RAM can be overclocked more by raising the voltage and timings.
Setting the FSBRAM to 1:1 should be achievable by changing the MCH strap setting.

Thanks PanMaster. This is the tricky part. Please do elaborate on MCH strap. Shouldn't I just set MCH on auto and change the system memory multiplier SPD. I have been reading other forums on this issue and have mixed understanding. This is the only thing which is holding me back from overclocking .

Set the strap to auto then and set the other thing to 2B.

Thanks again PanMaster. Actually before reading this post this is exactly what I did only to be confirmed by your post. Now my FSB : DRAM is 1:1. One question though; if I manage to overclock my E6600 to 3.0GHz the FSB will be 333MHz and that means RAM will also be running at 333 MHz. If I want afterwards to get RAM back to 400MHz what will be ratio of FSB : DRAM ? Also will it crash the system if RAm jumps from 333MHz to 400MHz? Thanks again

I found that the auto boost thing was problematic when overclocking my Q6600. Anyway I just set the multi to 9 and FSB to 400, although with my board (EP45 DS3) I had to install a fan on the NB as it was very hot.

Last night I started overclocking and I am using SP 2004 Ortho. At 276MHz FSB I was getting Core Temps of 56-58C after 30mins of small FFT testing. CoreTemp shows TJ max to be 85C. This morning I increased FSB to 286MHz and the core temps reach 60-62C and beyond .I carried on overclocking and now the FSB is currently 306MHz and I reach core temps of 65C .
However when I start SP 2004 Ortho I see that after 2-3 mins the Ortho screen disappears and thereafter Coretemp screen disappears so its like that they freeze for about a minute and then come back on the desktop screen and the temps have increased much further quickly.
When I stop Ortho; if the temps were 65C they quickly go down to about 56-57C and then decrease much slowly. So I want to know if this happens with you guys or is this a glitch. By the way I am using CoreTemp 0.99.6 and idle temperature is 35-36C.
