Q6600 - Lapped CPU / Heatsink

never nice clocks no matter how you look at it, i just got my thermalright ultra-120 extreme today and i'm very impressed
 
Well just got up to check the PC and annoyingly it failed after 6 hours so going to up the volts a touch and try again... hopefully a screeny of 3.745 on air for the Q6600 thread later today :)
 
Pneumonic M8 What is your Vid via core temp/ CPUZ when stressing. What is the voltage setting in the Bios for 3.745Ghz out of interest (is the Vdroop bad?)

BIOS Vcore is: 1.5125 (Edit: thought I was at 1.525, but wasnt! but now am :) )
Idle: 1.472 (thats at x6 multiplier have speedstep on)
Loaded: 1.410

VID: 1.2625 (what is this?)

I can raise the vcore a little more temps are ok fully loaded am at: 62/62/56/56 so still some room to play

VID is the stock voltage for a given chip and that the VID can vary from chip-to-chip
VID is = "stock" vcore for stock settings.

Technically the lower the VID, the higher the O/C ability (other factors taken into account ie pending the chips ability, motherboard limitations ect, ect)


Vcore set in Bios 1.525v
At load under prime 1.410v

VDroop= (under load) 0.115v

No its not that bad i have seen worse. All motherboards suffer from VDroop some worse than others

All motherboards in existence will have some form of voltage "droop", as voltage itself will never remain a constant, even if you set it at a precise value. There are too many variables to determine and change the voltage.

Examples:

* Fluctuations In Current
* Fluctuations in Resistance
* Fluctuations in Resistivity
* Fluctuations in Temperature


Voltage "Droops" often occur when the voltage regulation systems of the motherboard and CPU disagree with each other. The CPU in it's own right controls what voltage it wishes for, but the BIOS and the motherboard can change this value as they are the dominant factor in terms of supplying power.

Due to the Voltage Regulation system in ASUS motherboards you will notice that there can sometimes be a substantial "droop".

The "droop" will have a "lesser" effect if the CPU is operating in an idle state. When running at a load state the "droop" will increase as more load is active on power units.

ok thanks for explaining that! well am going to stop for today and set it off at 1.525 tomorrow whilst I am at work... hopefully will come home to a completed test :)
 
Thanks... well got 3.825 stable for a couple of hours earlier evening but cant leave it running over night... then had a fiddle with this 2p thing... so tomorrow evening will fine tune and then leave it running wednesday whilst I am at work so we will see what happens :)
 
I might give this 2p trick a go,I only feel comfortable re-seating my TRU ex with the motherboard out and infront of me, it gets a bit tricky (it`s sharp isn`t it :D). Nice clock on air mate !!
Please keep us posted on the results,

Cheers

I tried last weekend but my board wouldn`t boot at 420 fsb .I think its at its limit.I`ll try again soon.

UPDATE: just tried it , won`t boot at 420 fsb, even tried 1.6v.

I`m more than happy with a stable 3.7 ghz with CS2 & Capture One both loading in around 5 secs ,,, result !
