Hi all, im currently running my q9550 at 4.36ghz,

in the bios its set at 1.4000v
in windows idle it sits at 1.3600v
in windows 100% load it moves between 1.312/1.328v with slight vdroop

So which reading should i go by?

Intel states the VID range for this cpu should be no more than 1.3625V, so am i outside of the intel range by the bios, or just under by the idle reading in windows?

Finally, what do you think the MAX volts i should use outside the intel range are?

Cheers
 
I myself allways go by what load vcore is, im sure most others do the same.

So id have to say max load volts of say 1.4 would be the safest max to go to, unless u have very very good cooling.
 
well under prime95 after 4 hours max temps have been 63c under the vcore i posted above. Idle at 40-41c

Intel also says 71.5c max temps, so i have a few more voltage increases i can go to then?

cheers

Are u going by core temps or overall cpu temp, as intels max temp is for the overall cpu temp.

If that 63c is ur overall cpu temp then yup u can push abit further on the vcore, also remember not many things u will do will have heat output like prime, my gaming temps are allways like 10-15c lower then prime, ambient dependant ofcours.
 
I tend to trust cpu-z, both on load and idle. Voltage is supposed to drop when under load, this doesn't mean cpu-z is reading anything incorrectly.

At idle the chip is probably quite cold. It's the combination of high voltage and high temperatures that causes problems, so I aim to keep load voltage within limits I've (basically arbitrarily) chosen. I don't really care what the idle voltage is.
 
yeah i gathered that, my gpu usage is normally higher anyway, and i dont have many apps that run anything constant over 60% usage or something.

how can i find my overall cpu temp, i only see temp for each cores.
 
Ok cheers mate...

well im idling at 34c according to that, which seems more accurate as that is what i get in the bios, so i have more overclocking headroom :)

wil find the max temp with a few prime tests now..

ok im not sure how the readings work here exactly, after 40 mins or so prime, here are the results:

Bios: 1.437v
Idle: 1.408v
100% Load: 1.344v/1.360v

TMPIN0: 38c Max ??
Core0: 60c Max
Core1: 56c Max
Core2: 62c Max
Core3: 61c Max

Readings from HWMonitor.

I dont understand why the TMPIN0 reading is almost half the temp of each core??

I have pretty good air cooling, but surely thats not right!

nope, defo the max at 38c, the min is 36c, i dont want to rely on that too much, seems wrong.

on the other hand, it matches the temps in the bios health monitor section.

edit: TMPIN1 had 58c max though

I would'nt worry to much about the huge difference between the 2, the cores are and will go a lot higher then that, upto 90/100c, where as the overall cpu will only go upto 71.5c (well can go higher but best not too). Thermal throttaling takes into account the main cpu temp, so if u have that enabled in ur bios the comp will either stop the process thats causing all the load, or just shut down.

So basicly you still have a lot more headroom to play with according to those temps, but don't forget its now winter, so anything u do now may not work once the warmer weather comes back.

Keep an eye on both, but keeping the main Cpu temp under 71c is ur main aim.

Very nice temps, my overall cpu reaches like 45/50c normal days, just done a quick test now, but rooms cold due to window being open, so my loads are under 40 aswell.
 
cheers bifday2k, you have been most helpful.

i wont push too hard, im aiming to get stable at 4.35ghz-4.4ghz or so, still tweaking the bios.

im not sure what the difference in TMPIN0,TMPIN1 and TMPIN2 are, i will try and keep each core lower than 75c knowing the overall cpu will never reach that anyway.

now that i think about it, my north bridge does reach near those temps which i will have to sort it, im going to google those values see what they are.

quick google search came up with this:
What these temperatures are depend on what's wired into the associated chipset inputs on the motherboard. It can vary from motherboard to motherboard, so you won't be able to find out using HWMonitor documentation. The best place to ask is a forum that specializes in your particular motherboard.

Just checked everest, my cpu idles at 36c there, so that TMPIN0 must be the cpu sensor as you say, seemed rather low under prime testing though

cheers

ok here we are, a quick blast of prime to show some readings in everest and HWMonitor:

everest might need updating though, the core readings seem off compared to hwmonitor!

no probs, allways glad to be of any form of help, just to bad i don't know the answer to those sensor ones, but im sure someone here or even somewhere on the net there will be some info..

Good luck with your research and further clocking.
