Hello

Well After building my new system I would like to overclock it a little bit. Is gonna have a E6600 and as you know the stock is 2.4Ghz, well I want to have it at 3.0Ghz.

What I plan to do is increase the Front Side Bus up to 334Mhz which will make it 3.0Ghz (334x9=3006Ghz).

What I want to ask is that if this overclock is good enough for a newbie like me. Because I dont know anything about voltages or ram voltages or ram timings. I just want my processor to run at 3.0Ghz and thats it. Dont mess with anything else.

Will that work?????
 
You'll need 667 ddr2 or 800ddr2. Newegg has the 800 in wintec or ocz for about $64 shipped (512 meg sticks). 4 sticks should be enough. You should have no trouble overclocking with any decent 965 or 975 board. Bump up the cpu voltage to about 1.4. Write down your bios settings each time you make a change. You'll have to try some different memory timings and see which ones work best. If you notice your cpu temp rising above 60 celcius, you may have to get a better heatsink.

yes ill be using ddr800. im gonna be overclocking with a 680i.

When exactly should I bump the voltage to 1.4? Why should I try different memory timings? Which ones would you recommend me? my memorys (2x512 corsair) use cas 4-4-4-12.

I heard people going t 3.2ghz with the stock intel, thats what im gonna use (or maybe the zalman cnps9700 depending on my budget) but the intel is the only one i have right now

I recently bought an E6600 and OC'd to 3 GHz with an artic cooling freezer 7 pro. Even with this recommended heatsink/fan my temps under load are 59-60C. My case also has 5 fans for cooling. So I'd be careful using the stock hs/f that you don't fry the chip. You should up the voltage to 1.4 before you raise the fsb, then try lowering it a notch to see if it remains stable. Personally I'd use the 4-4-4-12 timings, and set the RAM divider to 4:5..... loads of people swear by 1:1, but 4:5 works best for me with DDR800. Hope it goes okay.

Are you in 3.3Ghz with the Intel stock fan? if so then thats amazing. what are your temperatures?

Also, While im overclocking of course ill be checkin the temperatures :D but just one question, why should I increase the voltage to 1.4v before overclocking? wouldnt that fry my cpu right away?

BTW I WILL stick with 4-4-4-12 because I dont want to mess with my RAM.

But thats why I asked "what if I overclock by increasing the FSB only?" and I still dont get it answered... :?

Ok this is the truth

I can do it, but I seem it risky for me, even when I understand all that guide I dont want to try it for some reason... :oops:

everything runs off ratio to the fsb, when you raise the fsb it raises just about everything else with it (eg agp, pci, pcie, usb, sata etc), just like the cpu clock speed.

I got it real simple here.

I have an intel 975xbx, E6600, Zalman 9500, 3GB Kingston DDR2 667.

Put that and a ATi FireGL3400, two WDSE16 250 SATA drives, two optical drives, a FD, a Antec NeoHE 500W PS into an Antec P180B with two variable speed case fans and the cpu fan connected to the MB for speed control.

Then I downloaded IDCC from the intel site, reduced the ram to 533, pumped up the FSB by 25% which brought the FSB up to 1333, ram up to 667 and CPU up to 3.0GHZ. Nochange to any voltages, other bus speeds or anything.

Runs a max of 44C.

Did not change anything else, no voltages, no PCI bus, nothing in BIOS. I used CPUZ to identify the memory timings when running my Kingston 667 ram at 533. Set that to 4-4-4-12, then jacked the frequency back up to 667 by raising the FSB to 1333. IDCC is a windows application. No ratio to change on an Intel 975xbx MB.

Actually if you have your FSB@1333 and set your FSB:RAM ratio to 4:5 your RAM will be at 833Mhz. You can't get 800 flat if you move your FSB to 1333. So you have to chose either FSB:RAM 1:1 (666Mhz) or 4:5 (833Mhz). There is also FSB:RAM 1:2 (1000Mhz) is an option if you have the RAM that can run that speed.

Well that doesnt sound bad right? since my RAM runs at DDR800, overclocking it by 33mhz wouldnt make a difference right? no risk of burn it or damage it...?

1.4v is safe enough not to worry about frying your CPU provided you have adequate cooling. I would be surprised if you could get up to your desired frequency without an increase though. The guy who has reached 3.0 GHz with no voltage bump either has an unstable system or has been fortunate and got a good chip. I've got two friends with E6600s and they both needed to increase the voltage to hit 3 Gig stable, as did I.

So this is what i have in mind so far

Once I decide to start overclocking first...

1) increase voltage to 1.4v
2)decrease RAM frequency to 533mhz
4) start increasing FSB together with ram
5) ***Maybe each 200mhz test if it is stable????***
6)get up to 1336mhz and 833mhz

What should be my increments? by 1mhz? 2mhz? 3mhz?

That 33Mhz O/C on your RAM should be fine. It's only running 4-5% O/C. Or you could run RAM at 666MHz and tighen the timing to 4-4-4-12 instead of 833Mhz @ 5-5-5-15

Just run Prime95 and test how stable it is at 833Mhz

Let us know how things go. I am planning my build in 2wks and I will have a similar setup to yours. C2D E6600 (O/C to 2.97Ghz), Aftermarket Cooler, P965 MB, 2GB DDR2 800Mhz

If you can get it to run with 4-4-4-12 great but you might need to reduce the timing if you find the system unstable. I quoted "5-5-5-15" as a common setting for stability.

Just in case you're interested..... when OCing my E6600 to 3.0 GHZ, I have not yet encountered a scenario where it has been of any use...... when video encoding my CPU usage is only 43%, and increasing the clock frequency doesn't improve the time it takes by much.... seems that the L2 cache is more important here. Brings time down from 9m07s to 9m05s. Gaming doesn't touch the CPU either......
