I am starting to think that the CPUID HW monitor is full of shit when it comes to temps. No matter what I do, it always idles at 41*C. At stock, or 4GHZ, it always tells me 41*C.

Click to expand...

that is the chip sensors not working properly.. not software.. mine sits at 49C according to core temp with an artic pro cooler..

at stock speeds and voltage under full load it dosnt move.. it stays at 49C.. as the load and heat goes up with clocking it begins to move above the 49C..

my current bios and abit guru show it sitting at 30C.. the original abit bios showed it sitting at 4C.. he he he

basically they dont read any lower than a certain point.. the chips or at least some of them have cpu sensor problems..

intel dont care as long as they read the high temps and do the throttle down business if things get too hot.. the idle temp only matters to tweakers..

trog

ps.. basically my original abit bios showed my 6750 chip sitting at 20C idle.. the same bios showed the e8400 chip sitting somewhere below 4C.. it could just be that the 45nm chips simply run very very cool.. too cool for the sensors to work at idle heats.. abits answer is the alter the algorithm to read 20C higher which suits me cos my fan control now works.. a 10C jump between idle and load is enough to kick the fans up.. how hot or cool my chip really runs i havnt the faintest f-cking idea.. he he

it could also explain why intel send out such a half sized mickey mouse cooler with the chips..

Well after a few days trying to manage a stable 4Ghz for 24/7 i think i finally did on "safe voltages"

CPU: 4050Mhz (450x9 - Batch: Q810A055)
RAM: 1080Mhz (5-5-5-15)
Vcore: +200mV @ BIOS - 1.39V @ idle - 1.36V @ load
RAM Voltage: 2.22V
NB Voltage: 1.42V
VTT (or FSB Voltage): 1.28V

Performed stability tests:

- Prime95: 4 hours of Small-FFT's (In-Place)
- Prime95: 4 hours of Large-FFT's (In-Place)
- Prime95: 11 hours of Blend testing about 95% memory
- Gaming for 3 hours @ Counter Strike Source + 3DMark 06
- An approach to 24/7 use (i got the chip past wednesday)

I'm adding a shot of the temps after 2:20h of Inplace Large-FFT's (i adjusted the TjMax to 85ºC according to the readings of the socket of my board ... by default it's 95ºC)



Tell me what you think :toast:

ps: Though i'm satisfied to could run 4Ghz @ 24/7 ... i'm having some problems tweaking the BIOS to get 4.3-4.4Ghz for benching due to the Vdroop or maybe other things ... i'll keep trying
