Hi all, at the moment I've got an E6850 on an Asus P5k running stable at 3.8Ghz (423 x 9, Vcore 1.35v on air. I am a bit reluctant to increase the Vcore any more however I've read posts on various forums about people increasing it up to 1.55v in order to reach 4Ghz +. Is temperature the limiting factor or is it just in the silicon itself? Whilst running CPU intensive programs such as FSX for hours on end, according to Core Temp 0.95, each core has never gone above 30 C. If Core Temp is accurate, that would leave me with a lot of headroom however I was worried about just upping the Vcore to 1.4v or something and then BANG. The PC is built into an Antec 900 case with an Arctic Cooling Freezer 7 Pro.

Overclocking limits for E6850

. Just watch the temperatures.I started to increase the FSB to 445 which equates to 4Ghz and in order for the system be stable enough to run 3DMark 2005 a couple of times and Super Pi, I had to increase the Vcore to 1.44v. The highest temperature recorded for any core was 41 C so I'm hoping that's it and the CPU will last until Penryn. The idle Temps, where it sits most of the time is 18 C on core 1 and 21 C on core 2.

I wouldn't wory about vcore until it goes above 1.5/6
I've got my e6600 at 3.4ghz on an asus p5ne at vcore 1.45 so if you're getting 4ghz out of almost the same voltage, i'd say that's one awesome chip you have there!
(I have same case and cooler btw and in orthos full blend testing I get 60 degrees both cores).
You really need a better test than FSX though to test the stability as something like orthos will really push it and prove whether or not it's fully stable.
btw you need to run it for about 8/9 hours, although some people here let it go on for 24 before saying it's trully stable.

Really dont worry about it, these Core2Duo chips can take a battering. Keep temperatures below 75 under full load and you'll be fine.
Even if the temperature does get too hot, the C2D's will automatically throttle and shut down the pc anyway.
