Just downloaded Real Temp in an attempt to monitor my temps a bit more accurately. Currently using Everest and Core Temp my Q6600 cores are running at 11,11,19,19. That's in a room where the temp is 20 degrees. Now I know that's not possible. I'm running a DIY water setup with a lapped chip so at best the idle temp should be getting down near room temp.
According to the advice from the author of the program I should run the CPU at it's lowest setting and add on about 5-6 degrees to room temperature as that is the temp of a typical quad on air cooling. Does anyone know if this applies to water cooling too? How far above room temp should my chip idle on a decent water setup? I suppose at the end of the day a couple of degrees doesn't make a whole lot of differece but it would be nice to be accurate.

And another question. :) Should I be correcting all the cores with the same value (ie keeping the difference) or correcting the hotter cores less (in other words making all the readings about the same)? In theory at idle with speedstep on all the cores should be running about the same with decent cooling. Or should they? :confused:
 
Hmmmm,

What bios version are you running?

Like you say, your idle temps are impossible for the cooling setup you have (I am assuming high standard water?)

As for altering them I would rather find a way of getting them to say the correct temp.

As for differences if you do alter them, I would keep them. 2 cores on mine always run a couple of degrees different to the other two. Some people with really bad non flat cooling block and cpu can see 10 degrees difference (or just badly mounted blocks ;)) so I wouldn't set them all the same.

As for what they should be at idle depends on the following factors.

VID of your q6600 and hence voltage required to run at stock
Quality of your entire watercooling system (pump, block, radiator)
Where your radiator is mounted to withdraw the heat.
How much/how little thermal paste you used.
How unflat your cpu and waterblock is
Room temp

etc, etc

What I am trying the say is that you will get about 100 different answers as to what their cpu is running at idle.

I switched of speedstep so I have no comparison however with speedstep off and my cpu at stock with a VID of 1.25v and hence less that 1.2v needed to run at stock I was getting high 20's in a room temp of about 20.

That's watercooled (not the best because the gpu is in the loop but pretty high end components).

But I have the same cpu and board as you I have found no problem with temps in both Everest and coretemp reading correctly. I am using bios 14 which is recommended as one of the best for overclocking the q6600 (well the best "official" one, from memory bios 16 beta 2 I think is the fastest but you will have to check Abit forums to make sure)
 
I'm running the 14 bios, also tried the 16 bios but both are reporting the same temps.
As for the watercooling setup - Fuzion V2 on lapped chip with MX-2, 1/2 inch tubing, Eheim 1250, 120.2 outside the case with 2 Panaflow fans, no GPU in loop. Room temp is currently 20 degrees.
The temperature thing is a bit of a mystery. I have been looking in the abit forums too but all the tempterature issues there seem to be over-reading rather than under.
 
Hmm nice setup and certainly will run it cool and as close to room temp as you probably can get.

You can probably get away with setting it less than the 5-6 degrees above room temp for the air cooled as yours is much superior.

However, I would rather err on the side of caution and be tempted to set it on the high side, say 25 degrees?

Okay it will probably then always show a couple of degrees more than it should but no bad thing in my books.
 
Yeah - that sounds like a plan. I'll set the cooler cores to about 25-26 and the hotter ones 8 degrees above that. At least I'll have an idea now what the temps are doing and can get on with seeing what this chip can do. :D
 
Well with that cooling setup, heat isn't going to be an issue.

Your limit is just going to be how good of an overclocking quad you have.

My gain for voltage goes exponential around 3.5Ghz. It only needs 1.3v (under load) to be stable at that.

3.8Ghz needs 1.45v under load (1.5v in bios) and still can't get 4Ghz stable with 1.65v in bios (guess I am been too ambitious ;))

However, my temps are still all fine at 3.8Ghz (around 70 under load but bear in mind my loop is not as good as yours and is cooling my extreme overclocked GTS as well)

So I guess you will hopefully end up with a very cool 3.6Ghz system for day to day and who knows what for a benchmark run.
