I don't see 4Ghz being possible with air on the 6300's personally, water could also be tricky. I needed to shove 1.55v up the 6700's ass to make it go at 4.4Ghz. Which by the way, I was told it wouldn't hit, but oh look, it did lol. 4.6Ghz was possible for a few seconds with 1.60v but I need to vmod the board to get more stable, and I doubt I'll be able to run that on my single but who knows with my single, its a beast!
The 6700 is going on Phase tonight if the board plays nice with me but the sodding thing is a POS and is just plain old not wanting to boot atm. I'll fix it though or RMA it.
Well, once i get my DDR2, it's going to be run for about a week using a stock Prescott HSF from one of my other rigs. During that time, I'll be modding my case a bit and redoing my watercooling loop, so it's going under water pretty soon
I have a feeling that rather than cooling, that the Mobo is going to hold me back. people have got 2.8-3 GHz on air prime stable at default vCore with the E6300....but you'll need a MoBo capable of way over 500 MHz FSB (stable) to even reach 3.5 GHz
The E6300's will probably be board limited cos' over lower multi, semi similar situation with the 6600's to an extent.
6700's + have much more usable multi's than the slower chips, makes it easier to get decent clockspeeds before running out of mobo.
Speed wise, from the stepping 5 CPU's 4ghz seems quite possible on air with a reasonable chip. Would imagine it'd be a little easier on water, but air -> water doesnt seem to yield a huge amount on these cpu's. They seem to like being frozen (where have we seen this before - *stares at dothan*)
The stepping 5 chips are certainly the best of the bunch, but you will probably run out of mobo before you hit the limit of the CPU which is a shame
The mods are a must as they are on bad axe also for hard croe clocking
Stepping 5 is a mixtre, whats the full stepping?? Stepping 5 can be B1 or A1, C1 C0 B0 right this min...and yes they are out and about. B0 and B1 are the best, c1 is okay but is not as good
Doesn't really want to go much over 390 MHz (FSB) prime stable. Almost impossible to boot over 410 MHz, but i am way under stock volts (at 1.18 after droop), and the stock intel cooler i'm using is a pos, so cranking the volts wouldn't be wise.
