Nick Soapdish February 18, 2008 Share Nick Soapdish February 18, 2008 i'm going to be running some CAD, CFD, and FEA simulations that will take days on my computer. i want to overclock the cpu to see if i can get a few saved hours out of it, and to generally test the system. has anyone here oc'ed a C2D E6750? or for that matter, what's a good oc'ing guide? rig: C2D E6750 Gigabyte GA-P35-DQ6 2Gb OCZ DDR2 800 PC6400 4-4-3-5 GF 8800 GTX stock fan on cpu Quote Link to comment Share on other sites More sharing options...
dragonfly February 18, 2008 Share dragonfly February 18, 2008 I have the e6600... Alls you haves to dos is bump up your fsb so that you have a new clock of 3.0, after you unlink (if it's linked) your ram from 1:1. I'm at ~3.2 with one bump up from stock voltage, whatever that is (been a while). So I set mine to 1420 (that is, 1420/4=355, 355*9=3200mhz) to get 3.2ghz. You might need to bump up your voltage at 3.0, but I highly doubt you need to below 3. Quote Link to comment Share on other sites More sharing options...
boiler February 19, 2008 Share boiler February 19, 2008 when I had my gaming computer with the e6600, I ran it at 3.0 GHz with the stock cooler without any voltage changes. It ran very stable as long as I had it there. I think Cujo has mentioned several times that the Core 2's can hit 3GHz without breaking a sweat and without voltage changes. Your 6750 should be able to easily do the same, although I'm not sure you'll notice a huge difference in speed between what you have now and 3.0 GHz. The stock fan should still be fine since the chips run cool anyway, but you might need to up the voltage a little if you want to go past 3.2 GHz.

Lord Chip Douglas February 19, 2008 Share Lord Chip Douglas February 19, 2008 Why/when do you need to tweek the NB and SB voltages? Quote Link to comment Share on other sites More sharing options...
Nick Soapdish February 20, 2008 Author Share Nick Soapdish February 20, 2008 im thinking of oc'ing it tomorrow evening and ill let you guys know how it performs Quote Link to comment Share on other sites More sharing options...
dwEEziL February 20, 2008 Share dwEEziL February 20, 2008 I have the E6750. I haven't bothered to look into OC'ing it though as I've kind of gotten out of that scene since my Koolance water cooled case finally died. For me, all I would do is slowly bump the FSB up, usually by 5 each time, until the system fails to boot. Then I would drop it back down from 5 and increment it by one until I find it's highest stable setting. I've never tinkered with the voltages though and I don't suggest you do it your first time on a system that you might be upset if you blow the mobo/cpu on it.

Nick Soapdish February 24, 2008 Author Share Nick Soapdish February 24, 2008 i upped the fsb from 333 mhz to 4000 mhz to get from 2.66 ghz on the cpu to 3.2 ghz. ran ntune, thnx allanon, and everything seemed good 3dmark06 ran at 9k at 2.66 ghz and now it runs at 12k oc'd Quote Link to comment Share on other sites More sharing options...
dragonfly February 24, 2008 Share dragonfly February 24, 2008 (edited) 4000 MHz, quite the feat! What is that, 36.0 GHz? Or I guess 32.0 GHz using x8 instead of x9. Edited February 24, 2008 by DarkArchon Quote Link to comment Share on other sites More sharing options...
