OC'ing my E6600

Right, I'm having problems trying to get my overclock stable with Orthos, I'm currently at 3.2GHz at 1.5 Vcore, (1.6 in the bios, 1.54 Idling.)

It seems perfectly stable in everything else besides Orthos, for instance playing games, running 3DMark06 CPU tests, Super PI etc are all fine.

My temps seem fine, 35c Idle and 57-60c on load so no problems their.

When at 3.2GHz.

3DMark06

Super PI

CPU-Z

Orthos STOPPED

Temps, Idle

Temps, Load

In case its helpful...

I can also lower the Vcore right down to 1.525 In the Bios and again everything's fine expect for Orthos failing so i raised the Vcore 3 more times and now I'm thinking I've missed something or doing something wrong here as i would have thought its plenty of Vcore.

My RAM should be fine as I'm running at 1:1 so atm its currently running slower that its rated speed and running at 2.1 volts, so i dont think thats a problem.

I've also upped the NB voltage by 0.3, yet still failing Orthos.

RAM/Motherboard in Sig, cooler is a ACF7 Pro.

Any idea's or suggestions, thnx in advance.

I'd say not enough VCore. It's under 60 with full load, so it's not even remotely close to throttling. I'd give it some more VCore.

60C is fine for stock speeds and voltage, when overclocked by 800Mhz and with a voltage increase of 0.2v you should ideally keep load temps at 55C MAX as "most" high overclocks will become unstable after this point. Orthos becomes unstable(stops with alarm) at 65C(it was a warm day). Adding more vcore will only add to the heat, Try keeping it cooler and see what happens.

1.5/1.6v

I'd look at something else to get your clock stable. My E6600 is at just under 3.2GHz (my setup doesn't like 400x8 but is fine at 399x8) at 1.33v (cpuz) and with out checking is something like 1.35/1.375 in BIOS.

What batch/week is your chip?

My E6600 needs 1.58 in the bios to stay stable @3.6ghz load 60 idle 45.

Not wishing to belittle your overclock, but 3.2GHz on an E6600 is pretty average. Most will do 3Ghz on stock volts. What we are talking about here is a more extreme overclock and for that, it looks like he needs more volts. The most obvious symptom of a lack of voltage is a sudden crashing and/or restarting.

That's exactly what I'm slightly concerned about, everyone else's chip seems to be doing 3-3.2Ghz on much lower volts than mine, I have however been able to get 3.2GHz stable now by dropping the multiplier to 8, (8*400).

I've also been able to drop the Vcore a few notches since dropping the multiplier as well, now I'm on 1.575 Vcore in the Bios and 1.49 under load, temps being 59c after 3 hours, Orthos stable.

Not wishing to belittle your reading comprehension but the OP is talking about getting his 3.2GHz o/c stable in orthos. Which as you yourself say is a 'pretty average' overclock, not what you go onto say is an 'extreme overclock'.

I'm saying that for a 'pretty average' o/c like 3.2GHz I feel that his CPU volts are too high, as 'most will do 3Ghz on stock volts' and that he should look at other settings to see if that's where the issue is.

And I know 3.2GHz is 'pretty average' but that's all I need/wanted for now, a nice stable overclock that I can use 24/7 with out too many worries. That is part from worrying that maybe I'm not 'extreme' enough.

thanks though.
