i want to order a q6600 early this week and i plan to overclock it to the max. so what chipset will have the best results? i would rather use ddr2 than ddr3 and sli and crossfire really dont matter to me. so whats the winner?
The best overclocking chipset is the P35 chipset. X38 with DDR 2 support is about the same as P35 in that regard, the DDR3 versions of P35 and X38 don't overclock nearly as well but they are decent overclockers just the same. The 680i and the P965 chipset are fairly evenly matched with some boards besting others on either side. Though I have had better results with P965 than I have with 680i SLI based motherboards.
This is what I've experienced across a multitude of boards using each of these chipsets:
P35 Chipset -530MHZ-550MHz FSB (Typical)
X38 Chipset -500MHz-534MHz FSB (Typical) (Limited experience with this chipset.)
P965 Chipset -450MHz-510MHz FSB (Typical)
i975x Chipset -410MHz-460MHz FSB (Typical)
nForce 680i SLI Chipset -430MHz-500MHz FSB (Typical)
nForce 650i SLI Chipset -425MHz-450MHz FSB (Limited experience with this chipset.)
ATI Xpress 3200 Chipset -470MHz FSB (Limited experience with this chipset.)
I know some people have experienced better overclocks with each of these chipsets than I probably have, but even so I think this is typical as this is the range I've come to expect out of some of these chipsets. X38 is new and seems matched to P35 in terms of overclocking performance and I hear people saying that the BIOSes for X38 are immature right now and we can expect larger gains in the future. I doubt this is the case as P35 has remained relatively unchanged in regard to overclocking as BIOSes have matured for the platform. An improvement has certainly been experienced in some specific boards and board models but the average range of overclocking results I'd wager hasn't changed much if at all. I expect the same of X38. Another noteworthy experience is the comparison between DDR2 and DDR3 chipsets. In the case of P35 and X38 it would seem that the DDR2 versions of the chipsets are much better overclockers than there DDR3 counterparts at least for the time being. If future BIOSes can improve any of the above mentioned chipsets, I think it will be the DDR3 versions that will see the largest gains.
Plz don't fall into the hype created by Nvidia, it was great for dual cores but for quad cores in general the boards aren't stable enough to run high FSB overclocks...also the chipsets run too hot, have loads of issues with 4 dimms and certain brands of ram... if you don't need SLI plz don't opt for an Nvidia chipset ... plus their new upcoming 780i already has issues with the new Intel Penryn which to me is not a good sign... surely not for us 680i users...
