5G result???  

I'm still testing my E8500 at 4G, lowering the vcore...currently running Prime95 at 1.275vbios/1.264vdrop...no vdroop on my mobo...quite surprise.
already passed 7hrs when i was leaving to work this morning at around 7am...hopefully no prob.
later on will only see how hi can it go...5G is a no-no on air i guess...

My original theory when I first started out was that 45nm and 65nm sensors were very similar with similar amounts of error. Intel's release of TjMax for 45nm showed me that I completely underestimated the amount of error in the 45nm sensors.

I couldn't imagine that Intel would be using a sensor that could be off by as much as +/- 10C at 50C but that is their official spec for the 45nm sensors used on the Intel Atom CPUs. Based on the data I've seen and user feedback, that amount of error seems to be what the 45nm Desktop E8000 and Q9000 sensors also have. Some sort of calibration is not an option for 45nm.

With the correct TjMax for 65nm, users should have very accurate temperatures from idle to TjMax. The 65nm sensors are far more accurate and rarely if ever suffer from saturation or sticking in the temperature range that most users operate at. The amount of slope error in these sensors is probably one quarter of the amount of error in the 45nm sensors. I think the latest beta of RealTemp is using the correct TjMax for most 65nm processors but it will be good to finally get this information from the manufacturer so all temp programs can finally agree at least to one part of the equation.

There are still a few minor things to do to RealTemp but it works OK so I haven't been too motivated lately. I've been having too much fun playing with my new Reapers! Not too bad for the old P5B.

even on water my e8600 @ 5ghz is idling at 49C and load at 74C... 

copy the post from xtremesystems real temp thread, post by unclewebb, the real temp program writer i think.

its seems tht 45nm proc sensor are more lousy and have more error rate compare to olderr 65nm proc temps... looks like intel using cheaper sensors on the 45nm.

tht's y everyone getting different temp readings, even my friend e8400 on my pc using same cooling also different temps...  not sure about E0 steppings though.

at least u touched the 5G mark...i can only dream i guess
if that is the case, then i dont dare to use IBT anymore. mmm...on 2nd tot, i never used IBT...only OCCT/Prime95/Orthos and yet if uncleweb is correct +10c is bad...wouldnt want to kill my proc yet...not till Nehalem came out and the price is stable for me to grab one

its +/- 10c, means ur temp readings might be higher or lower...

i using my e8400@4ghz@1.325v(bios)@1.35v windows, 1.33v load C0 steppings, running IBT on water reaching 72-76c depends on ambient... prime test is 61-66c depends on ambient as well, both idle at 46-50c depends on ambient as well. I suspect mine getting higher temp readings as my friends e84 more cooler thn mine... checked my own mountings though, yet my q9550 run cooler on the same cooling system     

correct...it's +/- 10c...but we need to look at the worst case scenario...so, if u r running IBT at 76c, how can u really tell the actual core temp is 86c or 66c...if 66c, then great but if 86c...not so great, isnt it. for me, occt/prime/orthos is enuff...IBT is too extreme for me even thou it generate error faster but issit due to the proc instability or due to the heat generated passed it's standard spec...
ur mobo got overvolt meh...no vdrop.
btw, maybe ur q9550 surface has a better contact...slighly concave/convex compared to ur E8400.

dunno... the new DFI bios tends to overvolt... set 1.325 in bios, bios reading 1.34, windows 1.35-1.36, run IBT 1.33v.

but the new 45nm really need fine tuning on GTL references to get lowerr vcore for OC'ed clockspeed... b4 i change to Q9550, i need 1.4v to run 4ghz on my e8400 stable. After go to quad and comeback to e8400, i only need 1.35v(assume mobo overvolt), but still one notch lower.

now funding for another mobo for better OC of my Q9550. cause whenever its over FSB1600, the P35 UT seems struggle with the 45nm quad, getting random instability prroblem, passing IBT + 8 hours prime, and will get random bsod once off pc and on again.

Ermmm...GTL is like abstract thing. Hard to know which one is sweet point.
Have to trial and error many many times.

-pWs-

i second that on the GTL Ref...after finding the sweet spot of my GTL (i meant the mobo one, not my GeniTaL  ), i can run my E8500 at 4Ghz wif 1.256v...the vid is 1.25v; so, quite happy with it.

wow, nice one.
can share me the gtl value?
the gtl u set is for cpu gtl and nb gtl? or just cpu gtl only?

i rahter use speedfan or using my mobo temp display...
using coretemp and realtemp, my temp fly up to 68c...
but if using speedfan or d display, it actually around 49-51c...
an i OCed my proc as my siggy...

mobo display temp is not accurate as it might differs with bios change...

so its not really safe to take that as the reading

if not mistaken, only the CPU: CPU1/3 : 62 and CPU0/2 : 60

how come i dun see the setting u mention? only got cpu gtl ref.. 0.63x, 0.65x etc.. is it this one??
can show the screenshot ar?

sorry, i was using lichetan bios screenie format...his bios using % format i.e. 62 which is 62% = 0.62x...in rampage bios, it would be 0.62x and 0.60x

how come i dun see the setting u mention? only got cpu gtl ref.. 0.63x, 0.65x etc.. is it this one??
can show the screenshot ar?
