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.
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.
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.
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.
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.
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.
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......
