My Vid is in my signature now.
My chip hits 80 degrees on Load @ 3,8GHz @ 1,392V :S
Want to know the funny thing..... my chip is a (look in signature i update it) batch number.
Very few people get that lucky with a L803-L807.
The chips I've had are:
L804, L733, L743, and L737
no thats under prime small fftsQuote:

I just got a quad up to 3.6ghz with 1.4v in the bios.. 1.38v in cpu-z
after 2 hours in prime core temp was showing 66ºC and real temp 61ºC
which one should I believe?
oh and by the way, the core temps were so different one from another that i ended up using a wire to pull up my TRUE a bit and now the temps are even across.
I get the same thing as u do, real temps allway being 5C lower. I trust core temp and everest, its safer. Plus 2 programs vs. one.
Set your TJMax in Everest and CoreTemp to 95 Deg to match RealTemp. See what happens.Quote:

Now I'm a fan of Everest, I use it every day. And coretemp has always been a standby. But to date, the soundest theory and best explanation and documentation come out of the RealTemp corner IMO.
Ok thx, so real temp is wrong to start with?
I wouldn't say that necessarily, it depends on who you ask. If anything, I guess I would be saying that Coretemp was "wrong" to begin with. The numbers for Tj Max are not formally documented, but if you read the setup and Theory and Calibration blurbs for Realtemp supporting using a 95TJMax instead of 100, it does make sense when you consider the validity of the testing done.
If you read on and follow the calibration steps for Realtemp, it's not really wrong until you see that your processor(in this case our Q66's) is significantly more than 6-7deg higher than your ambient with solid air cooling like an TRUE. Then you should make a small -ve offset to have it read accurately at IDLE. This should guarantee that it reads accurately over the entire range of temperature, and not just the higher load ranges.
In my case, running a fairly high end Water setup, my temps were 3-4DegC. higer than ambient at 1.6GHz/1.1v, which seemed reasonable to me. Hence I run no offset.
This all assumes that I am understanding the theory correctly. Maybe webb can step in and verify.
Thanks a lot.
Yesterday was a very hot day here. Today I'm much happier with the temps...
3.6Ghz / 1.38v / 56º Full Load...
I just bought this processor yesterday, big improvement over my old e6420.
You know what i say ...... you should research a lot better instead just staing things you find on the web about batches can and can't do as many ppl don't have the Knowledge and cooling to get 3.6ghz stable ... so automatically they say IT CAN'T do it, guess bad VID or whatever story they come up with.Quote:

Now i am not going to sit here and argue with you about what batches and what VID's do better as like i stated MOST can/will do 3.6ghz under the right conditions, cooling, users paitents to try this or that in Bios and so on.
Here is another recently bought L805 batch number (LINK BELOW) ... whether he is 100% stable in Orthos and Linpack is another question, but look at his Volts 9 x 400 1.38-1.39 which i have done that, but i wanted higher FSB .. So i chose 8 x 450 and to be 100% linpack and Orthos stable (11hrs 5min before i stopped Orthos) i had to use 1.43 in Bios.

I'm perfectly sure all Q6600s can do 3.6GHz, my point is is that there is a larger percentage of them that cannot do it COMFORTABLY... there is a point on every chip where the scaling is so bad that it's not worth it to pursue higher clocks.
I would say anything over 1.5v not very "COMFORTABLE".
There were lots of threads about people buying L80x batches and getting absolute crap chips that needed insane voltage for 3.6GHz up until L808.
There is no 100% again, as there are good chips in generally bad batches and horrible chips in generally good batches.
What I am saying is based off of personal experience and the experiences of others here... And I can assure you that I am VERY patient in BIOS. I test out every variable possible to narrow it down to the chip.
I think that you need to read some more about the experiences of Q6600 users here before citing lack of patience, experience, or adequate cooling as the reason people can't get 3.6GHz. I bet my first chip could do 3.6GHz @ 1.55v... would I be willing to run that even if I had water? No.
If you want examples of bad chips that would refuse to clock, look here:

Me neither.
Just wondering what do you guys think about a "safe" voltage to run at 24/7. My Q600@3.6Ghz temps are 50-50-45-45 at idle and 70-75 at full load. I heard some Q6600 degraded after a period of time so i'm just curious to know if I'm safe with my current voltage @ 1.44V in BIOS.
You're fine. Most say stay under 1.5-1.55v.
The reason I decided TjMax=95C for the Q6600 - G0 was because of what I saw during real world testing. Here's a couple of pictures I took 2 seconds apart.

Every other program has decided to assume TjMax=100C. There is no documentation from Intel to support that number and from what I saw during testing, that number is certainly debatable. This test was on my brand new Quad so I didn't push it as far as I would have liked and trying to get some good pics while juggling a camera, a temp gun and 4 cores without a heatsink wasn't easy.
CoreTemp and Everest using TjMax=105C for 45nm seems to be dead wrong but everyone still assumes that they are getting TjMax right for 65nm. Why?
Intel plans to give full disclosure on their 45nm sensors later this week at the IDF conference so I'm hoping that they also talk about TjMax for the previous 65nm generation to finally get this cleared up. If they have nothing to say about 65nm then next weekend I will pull off my heatsink and do a more thorough test.
Hey everyone,
This is a little off topic for you guys but I need some basic help. So I overclocked my Q6600 to 3GHz (did not adjust the voltage). Booted up into windows no problem. I then ran a couple of benchmarks and did a little gaming to make sure everything was running smoothly (Boy was I enjoying the extra juice:D). Later on in the evening I decided to go out so I left my system running prime95. Upon returning about 4 hours later I turned on my monitor and got no display (case fans and lights were all still on). So i cut the power and booted back up again and did not pass the POST. I switched my jumper and recovered the bios. I am running in stock conditions now.
Any idea what could cause the system to crash during prime95? Should I try upping the voltage to my CPU?:shrug:
Your overclock to 3.6GHz probably wasn't stable... upping the CPU voltage is the way to go if you want 3GHz.
Run Core Temp and check your VID also.
You may also try upping PLL and FSB.
Thanx again Loser. I'll give your suggestion a try, post again later.
The new 1.2000 VID chip arrived today, and so far it's a real Gem.
Temperatures should smarten up when the ambient goes down, it was 30degC. in here tonight. Bleck!
I'll let it run Prime over the next 24Hrs to make sure it's stable, but it's a darn good start.

Awesome, 1.2 VID is best isn't it?
Yea the lowest Vid, it should require even less volts then mine ( @ signature), cheers with such a rare chip
:D I used to trust Everest or CoreTemp against RealTemp about my Q6600's temp'...Quote:

Lowest VID normally provides better OC or less vcore.Quote:

My Q6600 G0, VID 1.2250v->Only needed 1.488v (CpuZ) 8x500...
BTW, With a P45, I only need 1.30~1.31v to run @8x450.
VID helps but Batch is quite important too.
(don't remember the batches... :p: )
