Ok guys, thanks for all your advice. I will give it a go tomorrow evening, im shattered right now but please bare with me on this, i need all the help i can get,@ Corey, i got the older keyboard with ps/2 plug but i left it at work. I will bring it home tomorrow and if the right side alt f12 does'nt work i will give it a go.Thanks all

Good deal. I'll be sure to check in and see how you're coming along.

Ok will do, wont be untill much later on tonight now, working a late one today. Thanks for the tip. By the way like i said before, when i aplyed the changes in the bios it tried to boot with no success, it managed to boot into the previous bios. This wont screw the pc up will it? i mean it will manage to boot into this version wont it as i will be basicly overwriting the previous version?

I would wait until I had a stable boot on the F7 bios before I over-wrote the back-up. Probably not necessary but just in case. Once I was happy F7 was a good update (not corrupt)I would flash the back-up (Alt+F12). It would be a real bummer if you some how had a bad bios flash and flashed the back-up to the same bad bios version. However the second I was able to boot into Windows I would flash the back-up before clocking. That stupid F4 will keep comimg back at you and ruining your OC everytime if you do not dump it.

I personally wouldn't go above 75*C and 1.35v, at least not until Intel comes out with some real data about voltages.

Hi Ivan, why 75c when the Tcase is 72.6c? http://ark.intel.com/Product.aspx?id=52214I personally wouldn't exceed 70c. I am at 61c now @ 1.345v (bios setting, measured in ET6 and CPUZ at 1.332v)

Hi Ivan, why 75c when the Tcase is 72.6c?

Because we're talking about (and measuring) the core temperatures and not the case temperatures. The datasheet talks about the case temperature limit. I think Tcase is about 10-12*C lower than Tcore.

All software is measuring Tcase not Tj. Any reference to Tj by any currently known software measuring application is an extrpolated value based on tcase to Tj Delta values and or assembled by a data base of actually measured data. This was always the contention amongst overclockers as Tj, was never able to be properly or accurately measured. Now Intel makes easy by providing Tcase in speciification.There is no reason in my opinion to use extropolated data in an estimated Tj temperature when Tcase is given.Therefore the maximum safe temperature is tcase 72.6c as stated by intel. This is the temperature stated in all current temperature reading software.

Gary,I'm pretty sure RealTemp and CoreTemp show the 'core data' by reading the "distance to Tjmax" registers.I can't attest to how correct they are, or how are they gathered. I was always under the impression that each core had a temperature diode or some type of DTS built into it (the cost of this would be negligent next to billions of transistors).

I'm with Ivan on this one. It was always Tcase what intel published in their specs:I7 950. Tcase = 67.9ºCI7 2600K. Tcase = 72.6ºCThe reading is from the cores which are supposed to be some 10ºC higher than Tcase as Ivan explained.

Hi Ivan, my understanding is that this software reads from the DTS on the case, they then use a compilation of data to determine Tj. Regardless of how they state Tj, I wouldn't (personally) use Tj as my set point. There really is no need for it since I know Tc. I will try to find some pertinent links to post.

Hey guys, heres the latest on my attempts to o/c. I had a go last night with no joy again , i have saved the f7e bios it seems stable enough. First i tried for 4.8 and the bios was showing a ram error when it was trying to boot. It didnt boot into windows so i tried again leaving the ram alone 4.8 with 1.36 v and it booted into windows so i fired up fsx default plane default airport and got the bsod so i lowered the multiplyer to 46 @1.35v and it seemed ok untill it started freezing upon booting into windows. I dont have a clue what the hell im doing wrong so i reset the defaults in the bios and im back to sqaure 1 with an easytune o/c @4.1. What am i doing wrong man??

From the optimum default bios settings, just set 45 ratio set vcore to 1.35v and set these settings below:Load Line Calibration .................................[ Level 1 CPU Multi Threading....................................[ Disabled CPU Enhanced Halt (C1E) ...............................[ Disabled C3/C6 State Support ...................................[ Disabled CPU Thermal Monitor ...................................[ Disabled CPU EIST Function .....................................[ Disabled Bi-Directional PROCHOT ................................[ Disabled

Thanks Gary, does that mean i should revert back to default in easytune or doesnt that matter?

ChristosWhat error code are you getting when you get BSOD? Also, what are your memory timings, system memory multiplier, and dram voltage?

Alright I am here to eat my words (but with cause; Intel sure did not make it easy; I confused diode and Tc and what RealTemp used as measure which is DTS).Using RealTemp 3.67, I would not exceed "Distance to Tj Max" of 30c This would equate to (using RealTemp) "Temperature c" of 68cReason: to quote Computronix, one of the developers of "Speed Fan" in regards to RealTemp says here about a 3rd of the way down the page http://www.tomshardware.com/forum/250157-29-q6600-tjmax-right#t1785354"Gradient look familiar? Much of unclewebb's and rge's recent testing shows that Throttling typically begins a few degrees below Tjunction Max, and that common Tc / Tj gradient values are about 27 to 28c. Now, let's summarize this information and put it into perspective. (A) We have Intel's IHS lab test temperatures which the end user can't duplicate, but are the temperatures shown for Thermal Specifications in the Processor Spec Finder. (B) We have the Analog Diode CPU temperature which Intel expects us to use. (C We have the DTS Core temperature which Intel does not want us to use. (D) As experienced overclockers, we all know that hot = unstable, so we don't exceed 25c to 30c Distance to Tjunction Max."
