Also, most chips will crap out and restart or shutoff due to instability from increased temps before ever reaching TJmax.

From all the reading I've done in Intel's data sheets, damage will likely start somewhere around 15C before TJmax is reached, but like everything else it just depends on the chip. You might have chips that start to damage at 20C. Though, this is also where stability becomes another factor. Running a chip unstable for can cause chip damage/degrading.

Just bare in mind, if you stay ~30C away from TJmax you should be OK.
I've been over TjMax... back when I had a CNPS9700NT I hit 103-105c for an hour. The log stated that the CPU was at 100c+ temp for 67 minutes.
TAT sure is a CPU killer
Still using the same CPU now.

There is no set GTL adjustment. Each chip/board have a different relationship. You are going to need to do your own testing. I've copy and pasted this info a lot these past few days. I'm going to be making a GTL tweaking thread for the & series boards
here soon.


Start by at least scimming this thread at EVGA. It's good to read it all though.
http://www.evga.com/forums/tm.asp?m=...&mpage=1&key=&

After you read that thread read this simple summary.

Quote:
OK then. Start with the highest 100% stable settings. With lanes set to "+0" not auto if you can boot that way.

So now that you have it stable and all lanes are set to hopfully "0". Start with lane 0. Increase lane 0 by +10mv. Test it each time you bump it. I personally ran 20 loops of IBT. Keep bumping it +10 until your OC is unstable. Let's say you where able to take lane 0 up to +120mv and it still be stable, any higher and it's unstable. Now you take the middle of 0 and 120, which is 60mv. Select that as your lane 0. Repeat process for each lane. It will take a while maybe even days, but after which you should be able to lower your FSB voltage and increase the chips stablity.


Now, if you have a lane that will not run stable at "+0". Say for example, you have a lane that is stable from +20 to +120, you again will need to select the mean(middle), which would be +70.

Here's an example of mine when I adjusted my quad at 3.2Ghz:

Lane 0 +80 (everything between +0 and +160 passed)
lane 1 +60 (everything between +0 and +120 passed)
lane 2 +55 (everything between +0 and +110 passed)
lane 3 +80 (everything between +0 and +160 passed)

After I did this testing I was able to lower my FSB voltage from 1.4v to 1.3v and then OCing to 3.6Ghz was nothing but adding vcore and NB voltage.

If you play be all the rules TjMax on Q6600 is 90C TcMax is 71C. TJmax should not hit 90C prior to TcMax hitting 71 this is due to calibration at factory ensuring Tjmax is always lower than Tc.

Even at stock voltage if you pull a heat sink you may not have a processor. They have come along way with this (anyone remember the Tom's artcile with the torched AMD?). and under any normal conditions this should not be done (removing the heat sink that is). Now with increased voltages if the thermal protections are enables via BIOS you should not run into this situation, a heat sink alone should bleed enough off to where the temp is not a immediate spike and be able to deal with the emergancy. Now with overclocking most people (myself included) turn off the safety mechanisms within BIOS that watch processor temps and take actions prior to Tc or Tj. So yes if OC'ing and running unprotected and kick the heat sink off the processor there is a chance there is going to be some permanent damage. Lets compare this is to someone finding a $10.00 hooker on the street and having unprotected sex, there is a damn good chance there is going to be some damage. maybe not life threatening but damage none the less. In both cases we know the risk and if we still make the decision to go ahead and do it, if something bad comes out of it we can't say we didn't know.
This is why after OC'in and testing I slow everything back down. The machine stays on 24x7 and gets used pretty often for testing stuff at work, I would be less paranoid with air cooling than water really. Air you still have backup fans in case that blow over sink. Water you get a steam generator inside your computer, no where for heat to go. I run EIST, TM1 and TM2 and C1E etc under normal conditions and have a rule in Nvidia monitor that starts a shutdown in CPU exceed 65C to keep safe. Not sure if anyone realizes this but I was watching my "kill-a-watt" (little box that goes between PC plug and wall socket that shows what you are drawing from socket.) But when I blue screened the machine was still drawing the same amount of power as when running. So in the event of a blue screen it does not all of a sudden stop drawing power but keeps sucking up what it was getting. I am going to measure temps during this kind of situation someday. What does thiis mean? Well nothing more than if you overheat and OS crashes your still adding heat.

Quote regarding BIOS safety measures
The power monitor continuously tracks the die temperature. If the temperature reaches the maximum allowed value, a throttle mechanism is initiated. A multi-level tracking algorithm is implemented. Throttling starts with the more efficient dynamic voltage scaling policy and if not sufficient, the power monitor algorithm continues lowering the frequency. If an extreme cooling malfunction occurs, an Out of Spec notification will be initiated, requesting controlled shutdown. Lastly, the CPU can initiate a thermal shutdown and turn off the system.

Thermal monitor function is not expected to be activated under these normal operation conditions. The thermal monitor mechanism ensures that the CPU will never exceed the CPU-specified parameters and guarantees functionality and reliability at any time.

End Quote

Lastly The graph you mentioned is from the thermal spec I believe, this is used to determine fan speed on the heat sink in relation to power draw and heat generated As temp goes up. Manufacturers use this as a base line for heat dissipation.

I gotta say it is nice to talk to someone that knows their ****.

I love these talks. Really makes you think about how things work. Which has brought me to a theory.

Theory: It's not particularly temps or voltage that degrade/kill a CPU, but excessive power consumption. It's a proven fact that the hotter a component runs the more watts it uses. Just like the graph I was talking about shows how many watts are being used at a certain temperature. q6600 G0 for example, at 71C with stock voltage it uses 130w. So when you increase the voltage the chip will use more watts at a lower temp. This is why we have to run our chips cooler in order to OC them. So 105w is the boards limit. Not so much a particular voltage or temp. Exceeding the 105w limit is what damages a chip.

Keep in mind this is just my theory. I'm try to think of a way to prove or disprove it.

Is their any way we can tell how many amps the CPU is pulling?

watt = amp X volt
amp = watts/volts
volts = watts/amp

lets go with a round number. Lets say the Q6600 is going to be running at the 120watt range at stock voltage (1.32)
120watt = 90 (amp) X 1.32v
lets up that to 1.5v (same amp draw) 135watt.
Heat is the enemy, most room heaters put out 500-750watts, your CPU puts that out to a very confined space. True power is also an enemy IE you hook a 120v circuit to the processor its going to pop regardless, but that is not normal operating scenario. Really if you can keep it cool enough they can be pushed and pushed until it is impossible to cool them anymore. Tom's set a world record a while ago
to do this they modded the regulator to 100Amp (from 90) used a liquid nitrogen pump for northbridge, I believe just used static LN in a special heat sink for CPU, etc etc.
I'll use this analogy from them, the P4 3.2Ghz chip they used was 112 sq millimeters, max heat dissipation is 84 watt's. a household iron is 2,000 watts over 200 sq centimeters or 10 watt's per square. So their 3.2 Ghz put out 8 times as much heat as an iron on a surface to surface level no OC. At TDP on a Q6600 (95watt) that is still 9.5X surface temp of a household iron.

Heat is the problem, if you up the Amps power becomes the issue, but other than that heat is the killer.

In a way yes. Heat causes it to use more power. I can prove this if I can find a way to monitor amps or watts from the CPU. Considering my theory, the CPU should consume roughly the same amount of power with stock voltage and full load as it would with an overclock/overvolt. Roughly 130w(q6600) with its max stable temperature. If I can find a way to measure either amps or volts I can prove or disprove.

When I started this blurb I thought the amps will be constant at 90A to CPU done by voltage regulator on board, I was apparently wrong. That would have made it quite easy to calculate. Instead we are stuck with 130watt max draw (theoretical) and I think I read 100 Amps. I say theoretical because a 90 Amp draw at 1.5v is already at 135watt. Unless the Amps are not running that high. Im gonna talk to a electrician friend of mine about this and see what he thinks on max rail power vs draw etc. The problem I see with nailing down draw to CPU is you have the ATX. and the 4/8pin connectors, plus the 5 and 3.3's all coming in from different spots but can be combined along the way. IE 12v from ATX can mix with 12v from P4 to give combined power. In theory the Q6600 TDP should be 105w or 95w depending on stepping.

Looks like you're on the same plain as me. Where did you get that 90A reading from. I've been searching for a way yo find my procs amp or watts usage but no success. Someone mentioned Everest in another thread, but I've yet to find a reading that tells me amp or watts.

the 90Amp max I got from Tom's hardware and the 5.0Ghz record machine. They had to mod the motherboard VRM to get above the stop point of 90

below blurb from this link: http://www.tomshardware.com/reviews/...ect,731-8.html

According to VRM [voltage regulator module] specifications, the voltage regulator on a modern motherboard is designed for a maximum current of almost 90 amperes. That means that sufficient safety reserves are available for normal operation - even when running the Pentium 4 3.2 EE (based on the Prestonia core in Intel's Xeon) with heat dissipation of 94 watts.

Now max on a modern day power supply (Antec Quadro) you have 4 12v rails each capable of 25Amp, 100Watt max 12v.

Now from Toms I think I found something quite nice. OC test setup with volt and watt listed so for 4259Mhz used 1.474v required 200watt power = 135 Amp, 3601.5Mhz 1.272v required 142 watt = 111 Amp and just for a nice graphable curve 3900.5Mhz 1.416v 158 watt = 111 Amp, actually that screws up the curve doesnt it, same draw, ok so 3300Mhz 1.296v 134 watt = 103 Amp. If I find some more reading will fire them off. As they are pretty specific about the power I beleive this is CPU only.
