Ok there has to be some offical intel documentation that gives a standard TJMAX rating to all cpu's based on model and stepping. There are no "dynamic standards"...



Well they dont have to care if they expect the people who buy their products to be sheep and only run at stock speeds with stock HSF. But then again there are so many factors that determine CPU temp. If I live in florida during the dead of summer and my A/C breaks I'd better know how hot I can run my CPU. So Intel should have a duty to set standards for TJMAX. Everyones ambient temperature wont be an ideal 22C.

I read that sticky and it basically says the same thing as the THG thread. I'm still not understanding why you want to read your temps backwards from TJMAX when you yourself say that the TJMAX # is worthless. Also, maybe you could tell us how coretemp is getting the TJMAX #s?

CoreTemp may not be as accurate as intels "trench" method. But who is going to do that? Coretemp is using the same calculations to get the temp on everyones computer. So although it may be off it is a standard point of reference that everyone uses and is accurate in that sense. I.E. Metallicas u120x is going to get better temps than my ultima 90... Coretemp cant distinguish who's heatsink dissipates more heat so why are his temps better? Because coretemp is accurate in a sense :)

Also we are all keeping a general rule of thumb not to go over 60C load. This is obviously very far from TJMAX on newer cpu's so there shouldnt be a problem if we adhere to those standards.

But im not sure what metallica is talkin about by adjusting his temps based on coretemps assumed TJMAX :eek:

As far as I know the sensors in the die work by reference to the Tjmax. They don't spit out actual temps. So, a program like CoreTemp will produce it's readings based upon the difference between Tjmax and current readings. If Tjmax is reported incorrectly then temps are reported incorrectly.

Edit: not go over 60 is fine for 85* Tjmax chips (25* cushion), but with 100* chips you are really short changing yourself if your looking for a higher OC.
 
Suggestion folks, better start the Intel cpu temp lingo in "how many degrees to max tjunction" instead of the absolute temp reading cause its meaningless, and usually will lead to confusion when discussing it.

Click my sig on "Using the Coretemp the RIGHT way" to straight this issue out.

The native diode reading relative to Tjmax is equally useless unless you know what Tjmax is. Either way, absolute temps or relative, depend on Tjmax to mean much. Best thing is to look at the delta from idle to load for the new heat sink vs the idle to load for the stock. The idle / load delta eliminates the Tjmax question (it's subtracted out of both sides) and eliminates the need to know ambient temperatures. Comparing the stock heat sink to the tested heat sink helps eliminate (or at least highlight) issues that might related to the rig rather than the heat sink.
 
Where oh where does it say that if your TJMAX is off then your tjunction is off? If TJMAX is attained according to stepping then the 85C or 100C in coretemp is not reading that from any sensor on the cpu. Alls that number is is the max temperature you can reach before cpu shutdown.


Everyone with the same CPU as me, TJunction says 100c.
Mine says 85c. It's not normal. The TJunction is suposed to be 100c, so if the TJunction is off 15c, i assume the temps are off by 15c.

CoreTemp says that my Idle temps are 15c. Normal idle temps are around 30 for the OC that i have. So it seems around right.

I don't know 100% if im right. That's why im scared to OC :D

Ok I got ya. I thought for a second there you were trying to tell me your temps were 15/30 haha. Unlikely seeing as your outside ambient temps are probably hotter than that :). So Core temp's website says the TJMAX is read from the "Model Specific Register" (or MSR). I wonder why it reads wrong on yours.

Sheesh lots of controversy, confusion, facts, non facts, bias, and misinformation on getting cpu temps. I still think its safe FOR NOW to just use coretemp + speedfan for comparing temps. TAT doesnt work properly on my CPU and abit guru reports a number that I suspect to be too low of a number to be accurate.

I think coretemp is reading the right temps .. i think its reading the CPU as something else .. or something since it has 85c .. :S

When you use the way Bing was saying, it just tells you how much room you have to go until you hit TJ. So, if your Load is at 50c, and TJ is at 85c, i think it will say 35c (thats the room you have to OC).
 
i don't mean to hijack this thread, but i'm looking at getting an intel C2D and to overclock to 3ghz. Will all of those power-saving settings work with the intel overclocked? I want the best of both worlds so i wanted to make sure it's possible/stable/achievable.

Yes the power saving features will work while OCed.

Your speed will be reduced, but your vCore won't. You have to be running stock for the vCore to drop.
 
Quick Update

I tried to get to 3.6 last night but I couldnt keep it stable. Orthos runs for about 3 minutes before erroring out.

I am currently running stable at 3.4:

8x426
vcore: 1.5
Vdimm: 2.0
MCH: 1.33
ICH: 1.12

Will I need to bump up VTT and ICHIO ???:confused:

I had my vcore at 1.56 and it still wouldnt run stable... Temps were 57C load @ 1.56 vcore. Also I noticed CPU-Z reports a lower vcore under load.
 
Not sure you might have to, i think it all depends on the chip
I have some cheapo budget corsair 667 dimms and I am doing 400x9 on the same mobo all default volts except cpu and ram at 2.0.

According to Newegg on the specs tab, that ram is rated for 2.2v, might wanna start there...
 
yeah but that doesnt mean anything, crucial rates their d9's at 2.2 while the same IC's in other brands dimms are rated for 2.0, probably why crucial ram dies so much

most of the crucial I dealt with did 450's 4-4-4-8 at 2.0-2.1, every dimm is different and these were orthos and memtest proofed.


for stabilities sake and to take the ram out of the equation you might wanna give it more than 2.0 but I highly doubt you need it to get 400mhz stable and error free.

Ok so at 3.4ghz my computer is randomly locking up running orthos. No errors... just a hard lock that requires me to press the restart button.

2.2 vdimm: runs for 5 minutes
2.0 vdimm: runs for 10 minutes
1.9 vdimm: runs for 20 minutes
1.8 vdimm: currently testing

Call it a hunch but I think the Ram is causing my pc to lock up...
 
could be, crucial ram is fussy as hell in some mobos.

try 1:1 ratio it might work out better

It;s currently at 1:1 . Running 850mhz I believe. I had it at 950mhz running @ 3.06 and it ran fine.
 
To get 3.6 stable use this (my settings, maybe it will work for you)

1.48v vcore
2.2v vcore
MHC 1.44v
ICH 1.19v
bump the VTT up 2 notches, that should be good.

RAM: 1:1 / 4-4-4-8/10/12 (all work for me)

Try that and let me know :D

Mad, do you have MSN? Or AIM?

Yes, PM sent. I'll try those settings when I get home. For whatever reason my ram likes to run @ 1.8v.. stock timings. When I set my vdimm to 1.8 orthos ran fine for 3.5 hours @ 3.4ghz. If I set it any higher my PC locks up.
