OK I've stabilized my CPU and RAM @ the following
____
CPU:

_______
MEMORY:

______
BLEND:

__________
CPU STRESS:


I'm worried about the Last test..which stresses the CPU only..it reaches up to 70 degrees..can any other process in my computer like games stress the processor so much? I would want you to take a look at the details if they look normal to you because I'm much satisfied with these speeds now..and I wish to leave them like that for future..

I have some good news for you: I noticed Core Temp is using the wrong Tj. Max for your CPU. The temps should actually be 20°C lower. The approximate Tj. Max for the G0 stepping of the E6850 is about 80°C [Source]. So, we need to change this in Core Temp (you may also use Real Temp and do the same thing - I actually prefer Real Temp, so I guess I recommend giving it a try to see if you do too). Here's how to change the Tj. Max in Core Temp:

1. Open the Options menu.
2. Choose Settings.
3. Change the "Tjunction Max offset" field from 0 to -20.
4. Click OK.

So, beyond that, all I have to say is that I think you should keep up the good work! Also, be sure to make the overclock stable enough to pass about 12 hours of the Small FFTs test. This will help ensure that you do not run into problems later on due to instability. You can also make the overclock stable enough to pass like 6 hours or so of the Blend test to further increase the stability a little.

And since you tweaked the memory, it's important to run Memtest, and get it to do like 5-10 passes. One pass is when Memtest completes all 8 of its default tests.

More later.

OMG..its more of a wet dream now

i cant believe I'm having 27 idle temperatures..but I have just one question..

• People tell me to keep an eye on the temperatures so it doesn't exceed the THERMAL SPECIFICATION of that specific Processor

http://processorfinder.intel.com/det...px?sSpec=SLA9U

The above details recommend i stay bellow 72 degrees...but i don't understand..that 72 degrees if for the NEW TJ settings? or the OLD TJ settings..?

but still...OMG!!

The good news is that the Thermal Specification is not measured at the core. It's measured at the same physical spot where the thermal compound is first applied by most people: dead center on the top of the CPU. Click on the word Thermal Specification, and then you'll see this:
And since the TDP was mentioned, I'll post that too:
In other words, the Thermal Specification is not really useful to us. At least it isn't to me. I mean, I care about the core temperature, not the IHS temp. And as Real Temp's Documentation (or "Installation & Calibration") page shows, it's much more important to go by the Distance to Tj. Max since the Tj. Max is much more important to worry about. And according to what ChickenInferno found and posted (in the Source I posted earlier), the Tj. Max for the G0 of the E6850 is about 80°C, so it's important to try and avoid getting too close to it, or the CPU might just shut itself off.

But, the main reason to keep temps low is to avoid instability. So many people love to panic and be like "omg the thermal spec says 71°C, and your temps are maxing out at 69 and 70°C!! Are you insane?!" I don't know what it is about Overclock.net. It's an awesome message board, but there's too much incorrect information.

But now I must wonder: if the Tj. Max really is 80°C, then I don't get why the Thermal Spec is 72°C. Maybe that's just the way it is, I dunno. But it seems kinda strange.

Now, it's also important to mention that Intel does not recommend that we use these sensors as veritable thermometers. Unfortunately, the lower the temperatures, the more inaccurate the readings. But as the distance to Tj. Max gets smaller and smaller (like 40°C or less), then the accuracy begins to increase. And of course, the sensors are 100% accurate if it actually reaches the Tj. Max. Therefore, Intel also recommends that we do not use these sensors to report idle temps.

In other words, our methods for measuring temperatures are extremely crude and rudimentary at best. But Intel left us with no choice. However, I heard that the i7s make it less crude and rudimentary (they're finally working on giving us more and more accurate sensors so that maybe one day we can use them as veritable and reliable thermometers).

In other words, don't take the readings you get literally.

Oh yea i just read the whole post and its quite an information..I should be worried more about the load temperatures..the way i imagine is that..when i run that first torture on the processor the temperatures go STRAIGHT up..i mean ironically that shows how the temperatures are WITH IN...

and about that thermal specs...i feel they are just making people burn their processors so they can sell more hahah..

and btw..i have a temperature monitor in my BIOS too..but that as well seem to have a 100 TJ MAX..so i guess that means its the data INSIDE THE Main board..and nothing relevant to the processor..

You're right. The one thing I usually say is "So, the only thing we have to worry about the load temps, unless our idle temps are ridiculously high, like 60°C or something". But I forgot to say it, so I'm really glad that you did.

Anyway, the problem about the Thermal Specification is that not enough people are sharing the correct information about it. I had to have somebody teach me about the thermal specification because I was originally taught that it means "this is the maximum safe temperature". I was even telling others the same thing: I'd be like "oh no! Don't let it go above 74.1°C!" But then I was shown that definition of Thermal Spec from the Intel Processor Spec Finder, and it changed everything. So, the problem is that too many people just don't know what it means. On top of that, too many people panic and say "never ever let the temps exceed 70!" because they just don't know.

And regarding the temperature monitor in the BIOS: it seems like 100°C is what is being used right now since the majority seem to be using 45nm CPUs (like the E8400, and the 45nm Core2 Quads). But it's best to go with like Real Temp or Core Temp and try to calibrate it to the right Tj. Max.

I guess that's it. I thought I had more.

That's more than enough for me man

I think if i ever have a problem i would just come and read these posts one more time..

but really..thank you for sharing such valuable information and helping me so much..tc

Aww...after looking at my temperatures at full load which was 46..i wished to overclock the CPU more..but im not getting more luck this time..

i jumped from 1600 QDR fsb to 1780..in the start when increased the voltage little by little, i couldnt make my computer to start even..so i increased little by little when i managed to cross the ACRONIS MESSAGE (just before the WINDOWS LOGO appear)..but nothing happens beyond that..i mean no matter how much i increase the voltage..the windows wont boot up..

i went up to 1.54 volts in bios..but no luck..my computer will always reset JUST before the Windows logo would appear..

i got back to my old 1600 fsb and old stable voltage...but i wish to know how to overcome this problem

Ok..i finally resolved it by increasing the voltage beyond 1.7 and it finally started to boot into windows..by that time i was having 1.6 in CPU Z..but when i ran the first torture on the CPU..it reset my computer and making me feel that it needs more VOLTAGE..but i just thought to give up because im not sure if 1.6 is right to be in CPU Z...

so here is my very very final...i guess :P





FSB:RAM
420:420
1:1

vCore is 1.5625 in BIOS..and 1.440 ~ 1.456 in CPU Z..
&
i increased my ram voltage from 1.9 to 1.95 to get it from 400 to 420..

Thats it for me i guess..i fear i just cant stabilize 1.6 in CPU-Z..even though my temperatures still wont exceed 64 degrees on that voltage..but dont know people just say U'LL FRY YOUR PROCESSOR IF U GO ABOVE 1.5 :S really?
