1400QFSB (350x9) = 3.15GHz -, 76C max load (4-4-4-12 700DDR) (0202 BIOS)
vCore 1.425v, nB 1.5v, vDimm 2.2v, +100mv used (in BIOS)
Note: 1.4v on core was unstable.
----------------------------------
Previously was stable at:

1334QFSB (334x9) = 3.0GHz -, 67C max load (3-3-3-10 667DDR) (0202 BIOS)
vCore 1.325v, nB 1.5v, vDimm 2.2v, +100mv used (in BIOS)
Note: 1.3v on core was unstable.

Test bench: E4300, Stock Cooler, P5N-E, OCZ 2GB R2 XTC

I'm going to try 3-3-3-10 700DDR next. Any more push on my vcore without a bigger heatsink and I'll be hitting 80C load. It looks like i'll be able to hit 3.3GHz with 1.5+ vcore. :D

I think you need a bigger heatsink - when you do get the new heatsink could you do a test at those exact settings to show the temperature improvement from the stock cooler.

Are you seeing bad Vdroop on the P5N-E?

I will do mate, but i'm still not sure whether I want the Tuniq Tower, Scythe Infinity or Zalman Aero CNPS9700. I've read far too many reviews with each one on top that it's more a question of personal taste. I'll make my mind up eventually.

Vdroop, I haven't measured at all but i'm guessing that's why i'm rebooting from Orthos at lower vcore, rather than failing Orthos.
 
I think I'm probably gonna go ninja for my new heatsink; because it doesn't involve taking the mobo out!

Is that the only one of the top end air coolers that will install without removing the mobo? I've read you can also install the Scythe Infinity without taking the mobo out. The Ninja (Rev.B of course) looks to be a possibility as well now you mention it.
 
Not sure tbh, I might get the infinity if it doesn't require it then :P

PS. nice to see another person from norwich around. Living in mulbarton myself :)

There are loads of Norfs on here. East Anglia seems to be pretty well represented as a whole between the Norfolk, Suffolk and Cambridgeshire types.

It's a great heatsink, but I tried and failed to install it with the motherboard still in the case. I wouldn't say it was impossible.....but it was beyond my skills.

Was just reading a mini-review of the e4300 in the new CPC, they had problems getting theirs to run any faster than 2.8GHz?
Click to expand...

Yeah - but they couldn't overclock using a P5N-E SLi either! The company that publishes CPC was caught reviewing mountain bikes from the manufacturer's literature in another of it's magazines a few years back. Given how often CPC reviews differ from the general reports on here and other decent technical forums, you'd have to suspect that they've got the catalogues out again.

Kaiju, selling the E4300 already? How come?

Want to try a E6400 and see if I can ramp the FSB on it. Then, realised I can't afford the increase in price plus a £30+ heatsink, so backed out a few minutes later. :D

edit: Found a LGA755 adapter bracket mount for the old Thermalright Si-120 sink I had on my old S939 setup. Hooray!

Item is back up on MM.

I just hooked up my E4300 / P5N-E / OCZ 2GB PC2-6400 Rev 2 XTC Series / Freezer 7 Pro today.

What a great combo. Booted up at stock (1.8GHz), went to 1066 FSB (2.4GHz) and now sitting at 1333 FSB (3.0GHz). Everything else left on auto/default. The RAM is synced so at those speeds it ran at 400MHz, 533MHz and 666MHz (5,5,5,15).

Temperatures are great - idle isn't above room temp and under load at 3GHz it's ~40C.

I'm going to give it a few hours of Orthos, 25 mins so far without error. Should I be running two of these or just one?

It's all in an Antec Nine Hundred - it's a pain to work with but the cooling is something else. With all the fans on low it's quieter than my old Sonata and there's a gale of cool air flowing through it.

Nice man, real nice. Next, 350x9... see if you can get it Orthos stable with a lower voltage than me. :D

334x9=3.0GHz, 1.325vcore 3-3-3-10 (667DDR) 2.1vDIMM, 1.5v NB
350x9=3.15GHz, 1.425vcore 3-3-3-10 (700DDR) 2.1vDIMM, 1.5v NB
356x9=3.2GHz, 1.475vcore 4-4-4-12 (712DDR) 2.1vDIMM, 1.5v NB
 
Are you specifiing your voltages? I set Vcore to 1.4 one time and it didn't boot, since then I've just left everything on auto and it seems to be working fine. Will gradually step up a bit further tonight but after already increasing from 1.8GHz to 3.0GHz I doubt I'll really notice another few hundred MHz.

I was able to get 350x9 to work with 1.425vcore and (+100mv) offset. Northbridge should also be manually set to 1.5v.

I'm by no means anywhere near as experienced as a lot of other people on here, I don't want your CPU to die or anything. :o

My first attempt at overclocking anything ever, all thanks to the info you guys provide in these forums :) . I'm sorry it's only an hour test, but this is my new rig and I want to get playing games ;).

Plus I never really game for more than an hour or so so it's seems stable for how I'll be using it :).
