what's been teh limiting factor on them? has it been motherboards or procs? If it's been the mobo, would watercooling the northbridge be an effective fix?
Mobos definetly for one. New BIOSes have allowed for more fsb increases since they first debuted.The only proc I seen that really hasnt lived up to the hard core expectations is the E6600. But wether its just the proc or a combination of proc and mobo I'm not sure. Its a good chip but alot of people expected it to be the sweet spot in value vs OC. It seems the 6300/6400 have the lead currently in this category. Although that could change with better BIOS and better mobos.
I dont know much about watercooling but it does help I'm assuming. Less heat allows for higher overclocks. Least ways the watercooling has always been able to get higher overclocks than aircooling. Now wether its worth the cost I cant say. I think thats one of those personal decision things and how much money you got. I'll let the experts give a better answer than mine.
speaking of Gigabyte DQ6 as that is the only board I have played with a conroe on , I have to say MB, I cant get past 480 FSB no mater what I do which includes water cooling and extensive modifcations to the north bridge and entire heatpipe assembly for proper cooling.
The cpu acts like it has a lot more in it as I dont have to push the Vcc very high and the memory will do more as I can drop the multi and still hit a wall at 480.
Water might have bought me 5 more MHZ but probally not, it mainly let me feel more comfortable about temps as I tried to push the core only to have MB FSB crap out. It is nice and quiet tho, even overclocked at specs in my sig, the watercooling radiator fans run at very low speed (1000rmp) and temps run 53C full load in a warm house.
as an off the wall idea.... would watercooling the heatpipes be possible? like opening one up and having water run through it. and if possible... feasable/worth it?
