If 1.425V gives you 54C load under Core Temp, you should be able to top off between 1.5-1.525V at around 60C - in the long term you don't want to go over 65C past 1.5V, and ambient temperature fluctuations will affect that figure.
You're testing load with either 2 instances of Prime or 1 dual-core instance of Orthos, right? Stressing just one core is not enough to determine load temperature.
On top of this, the motherboard may be a limiting factor, depending on your specific revision and sample. I've had a P5W turn unstable past 355 FSB, but there are many cases of people reaching 380 on this board - a little cooling on the Northbridge would have helped.
Yeah I'm using core temp and two instances of Prime. I know I have Prime set up correctly.
3.4Ghz @ 1.425V seems very stable. I'm going to leave it at that for now, and in a week or so after the arctic silver breaks in a bit, I'll see if I can squeeze a little more out of it. In my experience temps improve a bit after some break in time. Thanks!
well i have a similar system as your but the temps are not a problem for me i get at 1.5 vcore about 51 load.And 39 idle.That is pretty good.But i cant get even 3.4 with 1.5 vcore stable.I have now 3.02 at 1.425 and it is stable for 17 hours.I have same setting as you just the vcore is diffrent.
No no, my bad. The clock speed is 3.4Ghz @ 1.425. CoreTemp maxes out at 54C in Prime. It would probably go higher but I have my TJ07, with four 120mm exhausts and 2 80mm that blow right onto the tuniq in a desk cabinate. The back of the cabinate is open and the intakes are in the back of the case, so I don't think fresh air getting into the PC is an issue. The ambient temps, however, would certainly be better if the case were out in the open so the top exhausts could blow heat up and out more. It is a beast of a case and looks silly on my desk, and the cabinate cuts down on some of the noise from my raptor, so it will stay for the time being. I'd love to modify this desk with little grills so some air could get out of the cabinate, but I'm not handy enough for that!
my ASUS P5B Deluxe undervolts the cpu and makes the ram timings run at C4 and wont post with manual timings :S , im running my system (see footer note) with everything at default vcore except for ram (2.0v) running solid at 3.2 (400x8, E6600)with stock cooling! cpuz see's the vcore as ~1.296v so.
now with a newer case (thermaltake soprano, side pannel mesh removed for steel grill) i see it wont get passed 58*c!
Ill be getting a TT big typhoon soon so lets see how far this baby goes!
Forgot to mention that I pulled the case (TJ07) out of my desk cabinet, and I think that made a big difference temp wise. The thing is that when prime has been failing, it doesn't seem to be because of temps, because Core temp never gets above 55C. So I could give it 1.5 Vcore but since at load it is already at 55C, I'm affraid that I won't have enough of a safety zone for changes in room temperature. I would like to go higher though.
